:D it was critical for me to get new RAM too...so i got some crucial advice and have the same pc-4000 i think you got. I got the pair of 1GB chips, did you also? If you take a look at my signature you'll see i was able to get the crucial chips running @ 230mhz stable with some mildly loosened timings.

Can you let me know the voltage you have on you CPU and what HSF your using. I have the same RAM and I was able to get my 3000+ Venice to Post and do fine @ 250x9 with the rated 3-4-4-8-1t timings, FSB was also 250 and HT was on 600. And I did this @ the stock 1.4 volts. I even ran benches for a few days with no problems, but then I started to get BSODs. So I bumped the voltage to 1.45 volts and still no go. I'm just not really sure how much I should bump this processor right now with the stock HSF. I have an XP-90 which I just haven't installed yet since I already assembled everything before I ordered it. Thanks.

My specs are in my signature; i am using an XP-120 and my current CPUGUARD reading on CPU voltage is 1.57. I think it's set to 1.55 in the bios....
I could get my chip to about 2.6ghz (260x10) with very little voltage boost but the last 170mhz took .1v to get me there. I wanted 2750+ though ;)

My RAM might go higher than 230 @ 1t on this board stable, but i my only options @ this clock speed is 186 mhz, 230mhz or 277mhz. 186 was what i used my old corsair at. 230 is what this new ram does @ 2.5-3-3-7-1t...and my machine won't boot @ 270 on this ram even 2 3-4-4-8-2t.

I don't think it's your CPU's fault, 9x250 is only 2250mhz... drop your RAM divider and see if the bluescreens go away. At the same time, up your HTT to 265 or so. I bet it'll be fine.

FYI, all of my other voltages except memory are at the highest setting (NB voltage, LDT voltage) with the overdrive option ON. My northbridge is very. Very. VERY fucking hot.
I don't care :p
 
Yea I finally got it to OC I took my wifes Ram from her system and put it in mine LOL I thought she had 1 Meg but I must have only put 2x256 in hers But damn atleast it will oc now its PMI 3700. I only have it up too 2300 Mhz but I now know its NOT ME GOING CRAZY LOL I can't wait for my new ram to get here now and see how far i can get it up too. This Corsair SUCKS it wont go over 198 fsb it worked ok in my Mobil athlon as i have the clock set at 14 in it with a fsb 198 and I can run it at 2376 Mhz. I dont know whats up with it but no matter how I set it it wont run OCed in this system.Maybe Monday my new Ram will be here :D :D :D I'll post what I get it up too when I put it in here. My Aquamark 3d Scores jumped too im at 73,968 now from 68,372 so its getting better and I have not OCed the Vid card yet.
 
Has anyone gotten memory to run higher than 250 on this board?
best I can do is 145 1:1 or so with 2.5-3-3-6 1t. Thinking machine might run faster if I run it at
5:4 divider and put the cpu at 2.65ghz which puts my memory at like 216 or something. Any suggestions?

FWIW, in all the gaming benchmarks i've run, i've gotten no difference in framerates from my old setup @ 186mhz @ 2-2-2-5-1t compared to my new one @ 229mhz @ 2.5-3-3-7-1t. Sure, sisoft sandra says i'm getting an extra gb/sec of bandwidth..but that's not the bottleneck in any of the games i play. Maybe it would increase my quake3 framerates some. Quake3 is almost entirely memory bandwidth based. Unfortunately i already get 300fps in quake3, so i don't really care if it happens to run any faster, LOL... I would absolutely up the clockspeed of the cpu and just divide the ram again. CPU speed is gonna help more -- especially in a game like cs:source for example which uses alot of cycles on it's physics.
 
does anyone have problems with the resolution in boot up screen and bios screen? also what are the best settings for fan control? i've got a zalman 7700cu.

no problems with the resolution here
i'd turn cool + quiet off if you intend to o/c at all
 
ok, heres the deal..i got my res problem fixed but i have another question...i held TAB and it showd my memory to be running in 2T, is this not running in dual channel? how do you get it to run in 1T?

1t and 2t has nothing to do with single or dual channel. It's a timing option in the DRAM timings screen

hehe. ok so whats better 1T or 2T. I want the best! yeah i know...i have no shame. this is what happens when a console gamer tries to build a computer.
 
1t is faster than 2t, but is more stressful on your board, ram and in the case of an athlon64, CPU. Please read the athlon 64 O/Cing guide i mentioned in my previous post; it explains all of this in detail. I'm just re-typing what has already been written elsewhere.

The post is at:

http://www.hardforum.com/showthread.php?t=888001

The specific line is under "RAM SETTINGS"
Command Per Clock (CPC): also known as command rate, or CMD. Enabled = 1T = faster at a given speed. Disabled = 2T = slower at a given speed. there are some cases where you'll have to switch it to 2T for compatibility reasons though.
 
headless how are you uping the clock speed and dividing it, I have the same cpu as you and I want to up it more but I dont know too much about this MB, but im learning :D hwta are your settings in BIO's set at ?
 
Please go read the O/Cing guide. I'm not going to re-type everything that's already been written. The option in this particular bios is labelled "RAM SPEED AFTER REBOOT" i think, and shows you what the speed would be at your current FSB (htt) speed. It changes as you up your HTT, you can select it and adjust it in multiplied increments. At 275 fsb for example (as i mentioned in a previous post) you have the option of 275 (1:1), 230 (5:4?) or 186 (3:2? dunno for sure). There are other lower ones available but there's no point in running ram that slow.
 
Thanks I went over and read some things I will try out when my new ram gets here. At 2300 Mhz my temps are real good Idle 36c and after playing CODUO for 1and half hours, it was load 40 so it seems to be staying cool, this chip seems to run cool.
 
These venice chips really do run very cool. I was surprised when i got my first .90nm chip; it was winter here and i was idling at 29c, load @ 36c. Was a big change from my old .13nm a64..
 
haha, yeah, i thought those were pretty damn funny...s'like SHIIIIIIIT !!!!! ROUND HERE I ROLL ON 25'S AND I WANT SOME GOLD RIBBONS DAWG
 
Is there any way to determine what your HTT is at? I've set my HTT in the BIOS to 1000, but when I open up CPU-Z it tells me my HTT is at 200.9. I just want to make sure that my HTT is running at 1000.

Thanks
 
This is a bit of a confusing one because of the terminology being so easily mixed up -- there are two HT's involved -- HTT for your CPU is like the old FSB. It's default is 200; you need to raise that to O/C your CPU usually because the multiplier is locked. That in turn causes the HT link speed to be overclocked. HT-Link speed is 1000mhz (x2) at default, but in order to o/c you need to lower it to 800 (so when you raise the 200 HTT you don't go over 1000mhz ht link speed, just over 800.). Lowering your HTlink speed from 1000 to 800, 600, or even 400 makes absolutely no difference in performance.

That reminds me of another question I had. What is LDT voltage exactly?? That confused me so I left it alone. And also, how hot is VERY VERY hot?

Thanks for your help BTW
 
Once again, please please please PLEASE read the overclocking guide i've linked to above. It explains this stuff. I'm not trying to be a dick, i just know that i can't explain it any better than it already has been and my wrists hurt. Have pity on me, carpal tunnel sucks :D

Directly from the guide:

"LDT Voltage Control: Determines how much voltage the HT link will receive. You normally won't need to change this value, and some boards don't even have the option. More for debugging/testing purposes than anything"

Very very hot is too hot to touch. :) I'll get my IR thermo out tonight and get a reading off of the heatsink. It hurts to touch it which i think doesnt happen until at least 65c...
I'm sure that wimpy little worthless fan will die a rather quick death. The amusing thing then will be trying to find a replacement that still fits under my 7800gt. LOL
 
Ok im trying to setup a Raid 0 on this MB, I dont see shit about it in the Manual they give you, Jetway has a NVidia program that comes with there MB is there a Place to find the software or good Manual for setting this up ? I need info LOL this is my first 0 Raid setup. Thanks................. :D

Try different Tref settings to see if it some gives you a little more OC headroom.

Went through the last 12 pages of this thread and haven't seen a lot results from the flash to the Jetway bios. Just a waste of time? Or does the extra bios settings (memory timings?) get this mobo up to speed with its twin brother Jetway?
 
I havent been oc'ing like much of you but I just wanted to comment that this is great motherboard atleast at stock. Very stable and was shocked the onboard sound is so good to the point I may not replace my Audigy 2 if I can figure out how to get the 5.1 positioned right. Also the layout is the best I have ever seen and a PCI-E lane dedicated to one card a dream. For being free its awesome. Dont think I will sell it to get that Asus again. :cool:

I had to change my OCZ PC3200 Plat. Rev 2 1.1 (TCC5) for some GEIL PC4200 (3-4-4-8). I'm now running at 280 FSB 1:1 2T (3.05v). The board can go high with stability, but its picky about RAM. My 3700+ does not want to go higher than 2640Mhz at any voltage. :(
 
Dang. Just saw some some bios shots from the Rebel's Haven site. Bios looks exactly the same. No extra memory settings. They have a screenie showing 314 1:1 though. I had to drop the 166 divider on my EVGA to get the HTT over 300. No 1:1 for me unless I kick my TCCD out. Hmmm ... I have some old ADATA Hynis that ran 270 in my Intel rig ... I wonder ... :confused:
 
Well I found what I was doing wrong on setting up the Raid 0 lol I forgot 1 driver now that was simple it had me going crazy trying to find out what I had done wrong :D New Ram comes Monday and I will be a happy Camper.
 
I'm thinking that the Anand review of the Jetway mobo must have been using a divider when they went over 300HTT with their 2x512 TCCD. Polygon at Rebel's Haven reports that only 2x512mb sticks and higher have the +250HTT 1:1 problem. He posted a shot of 2x256 over 300HTT 1:1. Can anyone else do the same?

Ran off another SuperPi 32M at 314HTT with the 166 divider. Higher bandwidth didn't seem to knock much time off compared to the 133 divider run with tighter timings.

314x7166div5ar.jpg
 
Thought I should try out my Patriot 2x1gig set to see if the 250HTT problem got worse as memory size increased. It doesn't seem to be a problem. My 2gig set actually beat my TCCD 2x512mb set in SuperPi. Might have been the trfc adjustment I made. Previously I had just left it at its default setting.

I'm having problems changing my cpu multiplier. I was following the oc guide and on the first step it tells me to find my max HTT. I dropped my cpu multi to 5x but cpu-z and clockgen is telling me that the multi is still at 12x. MyGuard tells me that the multi is correct; but I can't get my HTT past 210 before one of my cores fail.
My specs:
x2 4800
2 x raptors 74 gb
1 x maxtor 300 gb

evga 6200tc
seasonic s12-600
 
I just posted this at the EVGA motherboard forum:

http://www.evga.com/community/messageboard/topic.asp?TOPIC_ID=7817&whichpage=2

"I was just able to try out a pair of GEIL PC4200 2x512mb RAM (Part #: GL1G4200DC RTL) at 1T also no go. This RAM was borrowed from an Intel 865 P4 Northwood machine doing 2.5-4-3-7 1T @ 265FSB, 2.75v. Hope this helps!

UPDATE! Although 1T is a no go I have been able to boot the board at 280FSB 1:1 with no issues (3-4-4-8 2T 3.05v), unlike the TCC5 OCZ PC3200 Plat. Rev. 2.

UPDATE (Part Deux): I'm typing this running at 330FSB! GEIL PC4200 @ 5:4 Mem Divider (264mhz, 3-4-4-8 2T 2.85v.) 600 HT. My 3700+ San Diego is at 8x330 at 1.525v. All I can say is WOW! :cool: "

It must be this Corsair ram, I have tryed 30 different ways too set it but it just does not seem to like it, I dont have it Overclocked and it just does not respond right, My 2500 Mobil Athlon was 10 times faster and never jittery like this with the same ram in it. I will know tonight when the new ram gets here. I hope it runs better then or something is really screwed up in this MB or settings.Anybbody else have a Problem with it be laggy ?
 
My new Ram came WOW what a Difference :D This system now runs good I booted to 250 fsb no problems right now time to test it a bit. I have a AMD 64 3200+ and now it finally runs good, man it was driving me crazy having new MB vid card run and running like hell. Headless what Volts are you running on your CPU Now ? and How high can I go ?

1.55v is what i'm running, and i wouldn't advise you go any higher..
 
Im Running 1.45 now and it seems fine at that, temps not too bad on air, im running my FSB 250 stable :D I ordered 1 gig of ram I thought I was getting 2x512's but I must have ordered and got a 1 gig stick, so I when ahead and grabed 1 more today so thats it for a month or so on this system lol . thanks for the info I dont want too push the volts to much and I think im not going to go any higher on volts.
 
Ok

I have this motherobard.

and I have an Enermax Model EG651P-VE (atx 12v, ver 1.2!) 550W/650Watt Peak PSU

It does 36Amps on the 12v, so it's got PLENTY of power

It has a 20 Pin (10x2), 4 pin (2x2), and 6 Pin (6x1) card-edge [like you would remember from AT style motherboards... "Aux" connector [Was intended for Xeon processor based systems]


According to the motherboards USER MANUAL (Yes, I RTFM'ed)


It says..

the manual said:
If you intend to use a PSU with 20-pin and 4-pin power plugs, make sure that the 20-pin power plug can provide at least 15A on +12V and the power supply
unit has a minimum power rating of 350W. The system may become unstable
or may not boot up if the power is inadequate.
Click to expand...

Now, what I want to know is this.

The motherboard has a 24 pin (12x2) power header on it, + and near the cpu it has a 4 pin (2x2) power header on it..
The psu has a 20 + a 4.

Do I put the 4 next to the 20 on the motherboard, or next to the CPU, and leave the "extra 4 pins" empty? - I mean, the PSU has 36A on 12v.. which is much more than the board calls for.. but I wonder if there is a "20pin -> 24 pin" adaptation or something that I need to be doing.

I really don't want to go and have to buy another $200 PSU, quite yet...

I mean, I see

This product
But it doesn't look like it's "Creating" extra wires from somewhere..
By, for example, my plugging in a molex header or something (which I wouldn't do anyhow)


This is my PSU


I mean, how many people with this motherboard have 24 pin, EPS12V powersupplies?

Can I convert the 6 pin Xeon into the extra 4 pin that it wants?
 
I just pulled the plastic bracket off a old P4 478 socket board i had and in stalled in in the P4 holes on thie motherboard, and in stalled my SP-120 no problem.

so all you need a a P4 bracket and you are good to go.
 
Malogato: Plug the 20pin PSU plug into the 24pin plug on the motherboard, leaving the additional 4 pins bare. Then plug your 4pin 12vATX into the plug on the board that is made for that particular plug (it's next to the CPU at the 'top' of the board.

FYI guys, I've been playing around with my setup tonight and think i've tweaked it to happyness @ 306FSB, 9x multiplier (2758mhz). This is the same speed (2750) i was running the CPU at before, but before i was @ 275x10. Now at 306x9 my RAM is running @ 250mhz 3-4-4-8-1T instead of it's previous setup @ 230mhz 2.5-4-4-8. I might be able to run it @ 2.5-4-4-8 @ this 250mhz with a bit of a voltage boost. Anyone have experience that says one way or the other for this pc4000 Crucial ballistix? I'm running some prime and OCCT now and if it survives the night ima update my sig and start this as my permanent config. Think i'll test it in some CS:Source too :D
