560J Question

[cditty]

Just started messing with my Asus P5AD2E Premium board. Used the CPU lock feature to drop my multi from 18 to 14 on my 560J. I'm running it at 3.73 Mhz with a 266/1064 bus speed, with my ram 1:1 at 533. Do you guys think it's better to run it this way or drop the FSB and go for a higher speed with the 18x multi... I'm pretty sure I can get to 4 with this chip, with the higher multi and lower FSB. It's running 3.73 at 1.3 volts. Any input would be appreciated.

Just benchmark it and see. The higher speed should make more of a difference. Benchmark testing shows that a 1066MHz FSB isn't that big a deal. So I would guess that clock speed should be your goal.

Hey what temps you get? I am considering getting one. Thanks

 

[cditty]

I'm using the Silent775 cooler. Right now, under full load (2 instances of Prime95 running maxing out entire CPU) I get up to around 58C at 1.3 Vcore @ 3.73 Ghz. It never goes above that. Idle is around 38C. I'm very happy with the processor and mobo. I would highly recommend it. Using AS5 for the hs compound.

similar config here.... just built it last night
Zalman 7700cu cooler tho.

1.3875v to the 560j

14x266 for 3.733, 1066 FSB, Crucail Ballistix DDR2-675@711 CAS5 and the memory bandwith is ginormous (I made that last word up) sisoft sandra is reporting 6451 for int and 6449 for float this absolutely smashes what I was getting 800 FSB any ram speed/CAS

P4speed....DDR2-XXX MHz........CAS........... B/W I/F
3.733...........711.........................5..............6451/6449
3.6...............600.........................5.............4858/4855
3.6...............533.........................4..............4838/4839
3.6...............400.........................3................4634/4628

I'm 46C Idle, 65C prime 95 load...... but heck... no thermal throttling so I'm good till summer. Yes, my case is well ventilated.


edit.... after seeing how far he under-volted his 560J I'm giving 1.300 a shot.... got my temps down to 60C prime95 load...endedit

 

[cditty]

It seems to love undervolting. I actually ran Prime with 2 instances for 14 hours at 1.28 vcore. It passed all tests, so I put it up to 1.3 and left it. Great processor.

 

[jfb9301]

does 2x prime95 really show a difference? (not a jibe, I'd like to know)

if I really want to put a load on my rig I usually use 1 prime95 to ensure a major load on the processor, while running ATITools 3D view to max out my video card. This usually shows me higher tempuratures than any video game, while stressing things to the max. If I really wanted to I could play a CD and run the cdrom and the sound card, but I can't see where that would make much difference. My prime95/atitool combo got a max temp for the cpu @ 61C. This thing seems to love 1.3v (I didn't notice lower settings in the P5AD2-E Premium BIOS)

I'm big on overclocking my rig, but I'm not sure I'm going to push the wall on this chip. I'ts as hot as a snakes ass in a wagon rut. My goal is get something that is both performance and stable 24/7/365. Right now its winter and the room is only 69F. Summer is coming and I'm moving to Hawaii this summer, so I'll be happy if I can keep 3.733 out of this rig. While I might go looking for where it tops out I'll probably keep the 3.733 with the humongous bandwidth.

I'll try exact the same things your using 'cause they are all available at Microcenter here.

 

[cditty]

2 primes max out both logical processors when you are using hyperthreading. I did not even search for the max of this chip. I'm pretty sure it would do 4Ghz, but it is 100% stable at 3.73. The temps are good and the voltage is low. So, I'm staying there... for now.

 

[jfb9301]

just finished some dual prime 95 testing at this end. Functionally the same as Prime95+ATITool with the exception that you are not hammering on the video card.

P4 @ 1.3v, Max temp 62C, reguardless of room temp of 62F-69F So I'm thinking case ventilation is way more than sufficient with a 12cm intake and a 12cm exhaust moving 70+CFM (when running @ 7Vdc) through the case. This machine screams

 

[ImLazZzy]

Just finiished upgrading -- 560J with Silent 775 and X850 XT PE. CPU idles at 38C-41C (room temp 72F) while 62C full load. Played a little Doom3 @1600x1200 Ultra with 4x anti-aliasing and got 60 FPS and 58C CPU temp. with eVGA 6600GT, I couldn't see the post on my Apple 23" but the first time I booted up my comp after upgrading this afternoon, the ASUS logo showed up right away! Great!

Oh, my! Did you replace the stock fan on the Silent 775 or not? There is no way to make it spin faster than 2350 rpm on my computer. My 560J started to run very warm after a while. I got low idle temps but very high readings when it's under load. I replaced the Silent 775 with a Zalman cu7700 this morning. but it couldn't cut it either. Temps went up to 70's even when running 3D2003.....ouch! I am pretty sure the ventilation in the case is OK. Man, isn't this tough!

 

[cditty]

I'm running it stock... What specs are you running everything at?

Chris

 

[jfb9301]

Check to see if ASUS's Q-fan control is enabled. If I disable mine it runs the fan @ 100% (and it's louder than I thought it would be). If Q-Fan is enabled it will run the fan at reduced RPMs until a set temp is hit and then spool the fan up. ASUS selected an amazing high Tcore as the default for this setting (something like 60C or 63C so you wont hit max RPS until 70C or more ). I cranked it down to start upping the fan at the lowest setting (53C) and by the time I hit 60C my fan hits 100%. Since @ 100% I max temp at 62C this is perfect . Quiet when I'm idle and cool when I'm loaded up.

Boy! I've done that, but it didn't work. How tight you screwed the HS into the mounting base? How much grease you applied? I used AS5 ....Geez....nothing worked. It must be my case then....BTW, the Zalman has two fan modes but te max fan speed is only 2000, even slower than Silent 775, which is 2500. I wish I could make them go wild like the Intel stock fan ( 5000+ max)

Grease. Follow the AS5 instructions or mine, do not follow Zalman's instructions. This is what I would use for AS5 for any heat sink, mounting to a P4. Put a dab on the heat sink and the processor and then removed all but just a trace with a credit card (you should see a lot of metal with just a hint of AS5 here as only deeper gaps are filled). Then applie a approximately 1/2 of a BB to the heat spreader. Don't smear it around the crushing weight of the heat sink will do that and minimize air bubbles. DO NOT USE the zalman fanmate. ASUS's bios will do the same with Q-fan in PM (pulsewidth modulation, the other method is for the 4 lead intel cooler which we are not using) ) method. Better actually, as ASUS Q-fan will do it automaticly based on Tcore readings. Vice fanmate which operates on the temperature of the fan mate, which isn't even close to the core.

When installing the Zalman 7700. install the mounting bracket to the base per the instructions. Ensure that all 4 mounting screws are tightened firmly (super torque is not necessary). with the mobo laid flat (or the whole tower with the mobo in it, in my case), carefully set the 7700 on the heat spreader and align it with the holes while pressing slightly (this will start spreading the AS5). Screw the mounting "grips" (s-type from the Zalman instructions) until the grips are comletely in contact with the support bracket.

Trust me, you do not want to hear a 120 spool up to 5000.... OMG my 2 sunon's at 3000 were so horrendously loud that I'm running them at 7volts unless I need some kind of emergency ventilation. The 2000 of the zalman should plenty. Unless I'm running 100% load my fan quietly motors at 1300.

case ventilation..... you can look at system temp (I have no idea where ASUS mounted this probe, but it is near the LGA-775 socket somewhere. A friend ran his board with the intel cooler and saw some insane (85C) temps on this one, when he used a zalman he dropped down to 28C. I'm sitting at 28C on mine too. so if you are using the zalman if you go greater than say 35C on the system temp probe, get better ventilation.

Try reducing the juice to that pressy. At cditty's suggestion I dropped Vcore down to 1.3v. That will save you 5C or more.

BTW I am using Speedfan 4.2 to monitor tempuratures and fan speeds in windows. While the fan speed features won't work, it allows me to see (on one display) all temps and fan speeds. Asus probe blows goats in so many different ways. You cannot display a temp in the tray for starters. The AI-booster program is no better, it looks way fancy, but same basic problem. Also AI-booster does not report correctly what Vram is, no matter what I set Vram to it reports 1.8. By the looks of things with a little research, I don't think the P5AD2-e can monitor Vram, it can only set it.

 

[ImLazZzy]

See, my problem is, even when the CPU is 70% loaded, the temp will gradually and surely hit 70C with about 20 mins. The system temp ( I am not exactly sure what it is, but I think you referred to the mobo temp) is pretty much around 38C. I will try to reduce Vcore. I am new to ASUS P5AD2-E, so not sure yet how to do that.I think the settings are in BIOS, are they?

Thanks a bunch for all the pointers! Reducing the Vcore worked. But I am wondering what the consequences are. Will it reduce the CPU speed as well?

 

[jfb9301]

Reducing Vcore will not make the processor run slower. But it will reduce the maximum stable frequency of the chip.

Vcore essentially controls the amount of juice applied to the CPU to keep it stable at what ever speed you run at. The higher the clock the higher the Vcore to keep it stable

Spec for a pressie is 1.4. But a 560J can do 3.7 quite happily at a reduced Vcore.

Reducing Vcore has a ton of benefits (if you can do it)

Longer processor lifetime

Lower Tcore

Lower Tempuratures for the mainboard

Lower temperatures for the power supply

but all these benefits may not help in overclocking. Sometimes it just takes some juice to make it happen.

I usually run Vcore as low as i can at a given clock. anything more can shorten the lifespan of the machine.

 

[ImLazZzy]

Very interesting! So you are saying the proc and the whole system are perfectly stable @1.3 Vcore, right? According to Intel, the Vcore range of 560J is 1.28 - 1.40. But for 550 (3.4), it says the Vcore is 1.4 (fixed). So if you lower Vcore on 550 to, say 1.3, while it still runs at stock speed, could it make it unstable?

 

[jfb9301]

550 @ 1.3.... you never know just like 1.3 on a 560j you'll only know if you try, milage may vary.

I've had processors run at all clock speeds, some had to be overvolted, some can be unervolted.

I had a Celeron II 600 1.5V which loved 1.9v (ouch thats a big jump) and overclocked to 965 on air at that voltage.

I've had P3s that I under volted by 0.1v. Its a matter of tweaking, research and good guessing which way to go, up or down.

Point well taken. Here is my story - I've actually had both 550 and 560J sitting around. I just replaced 560J by 550. Interestingly, the min Vcore for 550 is listed as 1.284 in BIOS while 1.300 is listed for 560J. I didn't go down to the bottom with 550: I set it to 1.300 and so far I think it's pretty stable. What do you know! I learned a lot from this 3-day battle against Precott's heat issue. I still need to give one proc back to the store tho. Well, I got this 550 almost half the price as that 560J costed me. So what do you think?

 

[jfb9301]

the board gives voltage options based on CPUID returns from the chip (or so I think).

Good going on getting the heat issue solved. The pressie is a wonderfull chip, IF you can tame the heat of the devil that comes out of it. A "J" chip should run a couple degrees cooler than one of the same clock non-"J" in theory, at least according to intel.

It's your dough dude. tho I'd give 266x14 (3.73 on 1066 FSB) a shot. if the 550 is stable at that keep it and return the 560J. If the 560J is stable and the 550 isn't, return the 550. Basicly I'd keep the cheapest chip stable 266x14. I know, most people say that 1066 isn't a big deal, but it does make some difference. Especially working digital media like MP3 and DVD.

When I started my upgrade I was planning on $1400, I bought the best I could afford (sometimes more than I could afford), and bought some things twice to get it right. I ditched my 2 week old Themaltake 480 like a dirty stepchild because it drooped on the 1.5, 3.3 and 12 volt rails. Not below ATX specifications mind you, just I'm not going to put 87 octane into a Ferrari. Antec NeoPower 480 now and no droop, zip, zero nadda.

The warden .... errrr um Wife just bought me a set of Logitec Z-5300 speakers (280 Watts RMS of pounding 5.1 surround sound, shakes the building). This is replacing the X-530 set (70 Watts RMS 5.1 surround, only shakes the walls) that I bought 2 weeks ago. Good thing for me she wants to start stereo wars with the upstairs neighbor.

This time around for me is the absolute best I can afford. I don't upgrade all that often.

 

[ImLazZzy]

LOL. Your specs are looking very good to me and now you have a new set of hellraisers..Well, I've been messing aroung with two procs, heat sinks, fans and grease for days now. Thermal wise, I somehow really feel 550 is a little easier to control than 560J. The temps under 100% load were totally acceptable on 550 even I didn't lower Vcore. It's another story for 560J tho. Without reducing Vcore, I didn't even feel safe when playing Doom3. Maybe the 200mhz increase does make a difference. BTW, what are the actual temps you are getting?

Based on my reading, since 5xxJ procs have C1E, they consume less power when idle. But that only grants lower idle temps. High load temps wouldn't be much different considering they are still Prescotts at core. While the J's also have thermal monitoring 2 which can reduce the clock speed when the core temp gets close to the threshold. Non-J's only have thermal monitoring 1 which only adds idle processes to slow/cool down the chip. I am still not sure whether TM2 has a big advantage over TM1 'cause with all the temp monitoring tools, the huss and fuss going on in our mind, we would definitely notice the high temps even before TM1 or TM2 is triggered. You might not care about these minor enhancement but you sure want to set the "C1 control" to "enabled" on your mobo to take advantage of C1E (you probably have done that...well, just a reminder). Anyway, I realize that 560J being not just a little faster than 550 so Im still kinda debating but I will definitely give 266x4 a spin. Thanks again for helping me out. Reducing Vcore is the key!

When I started my project, I was planning on dropping just a grand for everything except the monitor. Right now, I am looking at two if I keep 560J. My girlfriend has already started
whinin' for me being with my computer this weekend...

 

[Killaapp]

I'm loving the 560J - running at 4.1GHz right now with an xp-120.

The highest fsb I could hit was 287.5 with a 14x multi and somewhere around 1.33vcore.

I am now running 227.5 fsb 18x multi and 3.6 - 3.7vcore.

 

[ImLazZzy]

How did you change the number of multipliers? What mobo you are using? I will take a look at your sig. I just OCed my 3.4E to 3.74. Gotta keep going....I have a 560J too. but I've decided to keep the 3.4E since Its like $230 less than the J.

 

[jfb9301]

the Asus P5AD2E-Premium has a feature called CPU-Free Lock (or something like that) that becomes available when you set manual overclocking. It drops the multiple from whatever is stock to 14. Then just ramp the FSB out to 266+ to have a 1066 FSB and your P4 is @ 3.73 with all busses running at stock speeds.

Hm...sounds like a plan! Did you notice that Killaapp actually mentioned he set the number of multi to 18 before he dropped it to 14? I noticed the CPU Lock Free option in BIOS but I haven't tried it yet. I thought you could only drop the number but not increase it. I'll take a look. Thanks for reminding me all the same. but I don't understand why dropping the number of multi and increasing the FSB at the same time would still keep all busses running at stock speeds. The memory frequency has to catch up, right?

EDIT: By the way, I lowered the Vcore to 1.284 and upped the proc speed to 3.61. The system is totally stable. The proc and the mobo really make a good team!

 

[jfb9301]

the Asus P5AD2-E Premium automaticly adjusts the multiples for the busses as you ramp up the FSB selecting the optimum speeds. I belive this can be overridden.

anywho, a 560J is 3.6 or 18 x 200, on a quad pumped FSB, therefore 800 FSB.

A (not for sale) 3.733 is 14x266 with 1066 FSB stock. The only chipset to support this speed is the 925XE (for now)

So I'm running 14x266 for the processor, 266 quad pumped or 1066 FSB (still stock). ram should be 266x2 for 533 but Asus has an extra ram multiple that is 4/3 therefore my ram is at 711 (my crucial ballistix is certified to run cas 5 at this speed). My PCI clock adjusts to 1/8 therefore 33Mhz. Same sort of deal with my PCI-express clock. so basicly the only buss not at stock is the ram, but asus certifies stability at 711, if you use ram (like I did) that they certify for that speed.

what it all boils down to, for intel to release a 1066 FSB they had to add support for more multipiers than the 925X supported. This allowed ASUS to work some magic. The rest of the magic was the CPU-Lockfree which utilizes the bit available on high end prescots that allows the BIOS to under multiply the CPU to manage heat if it is overheating. for a 560 that would result in 200x18 (3600) down to 200x14 (2800) which is a major drop in heat load.

I just checked BIOS and I don't think specifying the number of multipliers is allowed on my P5AD2-E. I can only change the CPU LOCK FREE to either auto/enable/disable. Didn't see anywhere to set the number of multi. It might because I am running 3.4E instead of 560J? So the mobo drop the number automatically for you or it's selectable? I don't know if I set the FSB to 266, how the mobo would response after reboot. BTW, what's the difference between Auto and numbers for jumper free settings?

 

[jfb9301]

enable = 14 no matter what the chip
disable = whatever is stock for the chip, 18 for my 560J

your 560J should make it your 550.... milage may vary its only a 133 Mhz jump for the 560, its a rather nasty 333 Mhz jump for the 550

this will set either one to 3733


1 enable CPU Free
2 reboot
3 enter bios
4 advanced page
5 jumper free mode
6 go down to the freq, should be 200
7 (the important and undocumented step, there is no helpfull menu for this) hit the plus key 66 times (yea, stupid I know)
8 reboot

benchmark and stability test

Guess what? My P4 550 is now running at 3.73 with 1066FSB! I set the mem ratio to 1:1.33 so it runs at 711MHz. Did you set the ratio to 1:1 or 1:1.33? Also, what do you use to test stability?

various.... if it passes all... then it's good.

prime95+prime95+ATI Tool = serious workout for every part of the system
3D Mark 03 (not so much for the number, but it locks my machine if I push to far)
Aquamark (shows visual artifacting right before the lock up)

so far the overclocking gods are denying me 4 Ghz.

the best I've gotten on the 1066 multiple is 3.9 on a 1114 FSB and 557 to the ram
the best 711 ram I've gotten is 3.733.... something is holding me back and I suspect it's the 925XE chipset

on a 800 FSB base I've been able to get 3.9 again, but not 4 and my busses are way way out of wack. So I figgure I'll just go for the mild overclock and keep maximum stability.

from the first page:

similar config here.... just built it last night
Zalman 7700cu cooler tho.

1.3875v to the 560j

14x266 for 3.733, 1066 FSB, Crucial Ballistix DDR2-675@711 CAS5 and the memory bandwith is ginormous (I made that last word up) sisoft sandra is reporting 6451 for int and 6449 for float this absolutely smashes what I was getting 800 FSB any ram speed/CAS

P4speed....DDR2-XXX MHz........CAS........... B/W I/F
3.733...........711.........................5..............6451/6449
3.6...............600.........................5.............4858/4855
3.6...............533.........................4..............4838/4839
3.6...............400.........................3................4634/4628

I'm 46C Idle, 65C prime 95 load...... but heck... no thermal throttling so I'm good till summer. Yes, my case is well ventilated.


edit.... after seeing how far he under-volted his 560J I'm giving 1.300 a shot.... got my temps down to 60C prime95 load...endedit

and my sig...... I'm running 711 ram CAS 5 for unbuffered memory bandwidth of 5300 MB/sec and buffered in the neighborhood of 6450MB/s

Right now the Vcore is set to 1.33. I've tried 3DMark03+WMP+DOOM3 DEMO1 (will try other tests as you kindly mentioned) running at the same time and the CPU load was constantly 100%. Temps were hovering around 55C/56C. Im totally satisfied. Since Im really not too crazy ab't overclocking, I will keep it this way until I set up my A64 SLI gaming machine in the future or maybe the dual core, who knows. I am primarily using this one as my HDPC and for coding plus web design. So far, it's been serving these purposes well. But I have to admit that overclocking is a very intriguing field and the gain is well worthy the pain, not to mention one could learn a lot about this [H]ard stuff and of course, the pleasure to share with others

It came to my mind that you have tried 225x18=4050 or not. 225 doesn't seem to be be a big FSB jump....just a thought. Also, I've heard a lot of ppl saying they got stuck at 3.9 with a 3.4 proc. i thought with 3.6, it would be easier.

18x222 for 4.0 @ 1.30000v returns math errors on Prime95 with random lockups and crashes on benchmarks

18x222 is "benchmark stable at 1.3250v but bluescreens on 2xPrime95+ATITool. I could ramp the voltage up a tad more I suppose.

[edit] 4G nogo up to 1.3750..... tho now math errors @ 65C....

I'm thinking I'm at a wall... I can keep increasing voltage and therby increasing heat but I'm doubtfull of the returns.
