Love your socket 754?

Well, with DDR2 now taking over I've heard that DDR is on its way out and prices may just keep on climbing. Its a roll of the dice to see if prices will drop as it seems to be getting in shorter supply. I hope it drops but I'm not optimistic.

Yes, you are right about this... Since DDR2 demande is climbing thanks to AM2 and Conroe, manufacturers is shifting their resources toward DDR2 so what we will see is DDR2 prices dropping and DDR climbing. Supplies will dwindle daily and i'm sure it will be a irreversible process.

The best bet for a good priced DDR stuff is to get it secondhand, like FS/FT area here or feeBay.

Personnally, i bought mine when it's priced at 146$ for 2 Gb and right now, it's not less than 200$ new so this is a real trend sadly.
 
I have a claw hammer 3400 mobile on a DFI nforce 3 250gb. I came back to this after getting my new rig and decided to play with it again I had a prime stable setup at 250 FSB with a 9.5x multi at 1.55 vcore I believe. Now im playing with it again upped the volt to 1.7 and going to give it a shot to see what I can get. Im tempted to go a watercooling system for it to see what I can do.
 
I have been playing around with the socket 754 so far im running at 265 x 9... What is the max temp under load the socket 754s should be running at? I ran prime 95 earlier and my cheap at 1.7 vcore it went upto 75 C under full load. That sounds way to hot but was wondering what the rest of you guys got.

The majority would say that 60-65C would be the max. You will need to get a better cooling solution if you want to stay at 1.7v ;)
 
Im going to pull the gun and get another corsair nautilus 500 for this baby :). Any recommendations for replacement motherboard heatsinks for the sb etc? Im able to boot into windows with a 270 FSB with ram at 3-3-3-8 however it isnt stable yet I have to fine tune later today and see where I can get. I got some pretty good ram mushkin black line level 2 rated at 2-2-2-? at 400mhz. Im going to loosen my memory timings and try for 300 FSB and work my way down from there, got a corsair watercooling unit on the way ;) . Going to run the Vcore at 1.8 once I get my watercooling in. Hopefully I can get 300FSB x multi of 9-10 once everything is said and done.
 
Went 939 on a whim. Mostly to move to a PCI-E platform.

I have a 3700+ ClawHammer and a DFI LANPARTY UT nF3 250Gb FS if you guys are interested.
 
Good news on my RAM situation. I talked to a co-worker today and he's got a 2GB set of XMS laying around unused. I'm picking that up for $140 bucks plus a SLI bridge. Once I get that I'll put it in the machine in my rig and move one of the 1GB sets to the 754 rig. :)

how do u like the new 939 rig ? What setup did you get ?

here's what I posted in the 939 thread:

Went from 754 to 939 for no good reason. Went from a 754 3700+ ClawHammer to a 939 3200+ Venice. Some would call it a downgrade.

To be honest, Windows boots up a lot faster and so do my programs. Could be thanks to a relatively clean install though.

I got in on that Microcenter deal a whlile back and picked up the Asus A8N-SLI Deluxe for less than $50. I was in the process of trying to sell it when I saw a post in the FS/FT forum of someone that wanted to trade a DFI Ultra-D so I helped him out and traded.

I was going to sell the Ultra-D but wanted to test the motherboard first just in case (don't need any dead mobos on my mind). I needed a 939 CPU and a PCI-E video card to do so.

Picked up a a brand new Venice for $65 shipped. Found a Gigabyte 6600GT PCI-E (passive) for $85 shipped. Decided I would just keep this stuff.

The 754 system was watercooled so I had to take that all apart and it's already sold. Running the X2 heatpipe cooler for now and it seems to be working great. Very happy with how quiet the system is. Will likely upgrade to a Thermaltake SI-120 or a Ninja.
 
What motherboard are you guys using to unlock the multiplier? My Biostar board doesn't support it. I just bought another gig of Mushkin value to bump myself up to 1.5GB.

This board sucks because the only memory settings are 133/166/200MHz, there's no incremental dividers like ASUS boards and such.

So far I've got 12x209 (HTT 836/1672) for 2507MHz on stock voltage (1.4v, this is a 3400+ Venice 512K L2) This RAM is also running at stock voltage at CAS 2.5, not speedy RAM but it's good. I dunno how the 1GB will preform, as it's rated at CAS 3 but I wanted to keep Mushkin RAM on both modules.

I feel this CPU has a lot more headroom (possible 2700) and if I can find a decent board for $50 I'd probably jump on it.
 
kent: I'm having good results with a Gigabyte K8NS-Pro. The regular K8NS boards have a few less features but are otherwise exactly the same and are usually pretty cheap.

The only downside is my board only gives its best with one memory module installed. I'm very happy with my 1GB of OCZ Platinum but this board doesn't overclock even half as well with two sticks of memory in it.

It does allow you to adjust multipliers downward and has a good selection of memory adjustments and can run as high as about 325 to 330 MHz HTT. It's a good full size ATX / AGP board for the price.

ClockGen for the nForce3 is the best utility for overclocking and seems to allow multiplier adjustments even if your board doesn't support them. You can also run it during Windows boot up in a .bat file to apply your settings. Quite handy.

nullzero: You shouldn't be allowed to post links to water cooling kits. ;)
Now I want one!
The girlfriend won't be happy when my PC springs a leak in the living room.
 
Im using a DFI nf3 250gb... so far im booting in windows with a FSB at 350 :) will post a pic a little later still tweaking it :).

You are quite right about the 3400+. Mine is doing 250x11 @ 1.64v and running fairly cool while doing so. Unclewebb has a good board and so do I. Mine is an Abit NV8. Good cpu voltage increments (except nothing above 1.7v that's usable), good ram voltage adjustments (3.2v max) and great memory divider options (standard stuff + DDR433, 466 and 500 options). I personally stay away from Asus once I found out their vcore max is 1.55v which is pretty useless for a Venice core cpu since they seem to thrive in the 1.6-1.7v range.
 
My 3400+ venice is running at 2.65GHz now. I can't seem to reach 250x11 like you guys. My motherboard (here) is limiting me to 250MHz FSB and only +5.1% (weird way of doing it) on the vcore. That gives me < 1.6 volts on the CPU.
I can hit 2.65 and sometimes 2.75 but it might not be 100% stable there. Temps might be a factor so I was thinking about unliding it. Would that help at all or is the voltage what is holding me back?
Thanks!

We need to know what is the temps under 100% load before we can tell why...
 
From my experience with the skt 754 Venices (3000+, 3200+, 3400+) its the voltage that will hold you back more than anything. To get into the 2.7 range you need 1.6-1.65v. Temps don't seem to be a problem with these things unless you just have a really crappy hsf.

There's no advantage to unliding the processor and you will need a special heat sink to make up for the difference in height.

It sounds like your lack of voltage is holding you back. At less than 1.60 volts, even the OEM hsf is capable of keeping your processor cool enough.

Use CoreTemp and post what your chip is running at when running Prime.
http://www.thecoolest.zerobrains.com/forums/viewtopic.php?t=137

How much voltage is your CPU actually getting? Default is 1.40 volts so +5.1% is only 1.47 volts. You need at least 1.65 volts to get the most out of these single core s754 Venice chips. A little more than that doesn't hurt either! :)
 
Someone wish me good luck...

I will do the pinmod tonight for sure with the method of nigerian_businessman of stuffing a wire in the 2 holes then seating the cpu.
 
Did the pin-mod and it didn't blow up :D

I have a good and bad news :

-The good... The pin-mod worked fine but I was lucky to have a flash of doubt when I was about to put the cpu back. My flash turned up in that the pinup diagram was from the cpu back itself so if i place it on the motherboard, the orientation isn't really the same. In my case, i must turn the diagram clockwise one quarter and mirror it at the same time. With the bios option of cpu voltage set at off, it display 1.55 as VID (seems Epox pad with 0.05v extra despite the initial 1.4v to 1.5v from the mod).


and..


-The bad... It seems that Epox 8npa SLI bios is capped at 1.6v so no matter if i put +0.15v over VID, it still display 1.6v :( I will still try to prime95 and see if the cap is just cosmetic and that the real juice is indeed flowing. Id it fail at the same point as before, i will consider the pin-mod as not possible with this particular board without a bios mod to uncap it.

I would love to hear from others about the pin-mod and share their own results to confirm or deny my observations :)

Hmm, there must be a way around it.

There is a second pin mod you can do that will add another 0.05v on top of the first mod (that would put these EPoX boards at 1.6v stock)...maybe that will "break" the cap?
 
Got my corsair nautilus hooked up to my socket 754. So far so good :) im doing 1.92v for the cpu and running 38c IDLE. Still testing so will update on the load temp. Atm im running at 310FSB x 8.5. Memory at 258mhz 3-3-3-8 memtest is passing will do some windows benching after I try to see where my wall is on this clawhammer 3400 mobile.

Balls of steel my friend. Balls of re-enforced, stainless steel. Let us know how long it makes it before it asplodes. ;)

 
Hehe yeah I may turn it down a notch to 1.8v im just going to see where my limit is. Memtest just passed at 258mhz on the ram with 3-3-3-8 timmings. Now time to bump the bus up :).
 
I wouldn't be doing more than 1.65v daily on 90nm myself, 1.7v with good water, and even those are higher numbers than I'd be comfortable with (1.6v daily, 1.65v with water is more realistic). What kind of load temps are you gettin? Hell, I run water cooling on my lidless 165 and I use stock vcore because it scales pretty crappy after 2.8GHz. I think I have a dumper core that just doesn't wanna play nice.

Drop that down to at least 1.7v, jebus. :eek:

 
Ok its getting toasty hehe just started to stress it a little and the cpu is in the 50c range. Im going to crank down the voltage that 38C idle was from a fresh boot into the bios with no stressing hehe.
 
Running cpu at 1.75v now :p, good to know I can boot in windows with 1.92v though hehe. Memtest again ram at 275mhz 3-3-3-8 so far its passing.

Enough testing for tonight im hitting a wall on my OC around 2.6ghz :(

Running 325 x 8.0 right now its running good at that OC.
 
I accidently booted into Windows once with like, 1.82v on this processor I think? Something around there. I wondered why it hung for a few seconds before it posted. :rolleyes: Needless to say, I rebooted that bastard as fast as I could to correct that error. She's still ticking and diddn't lose any clockspeed or anything. I thank direct die watercooling, but if you load into Windows at 1.92v, meh, I suppose I wasn't as close to asploding as I thought. But yes, 1.92v....Jesus man, waaaaay too much. Maybe for benchmark runs on phasechange, but not for everyday lol.

You might not get much more than 2600 MHz out of a clawhammer reliably.

There's no performane advantage to using a sky high FSB / HTT so you might want to try lowering that and then use a bigger multiplier to see if that helps with stability.

I was playing with my Gigabyte K8NS today using a lower multiplier. I could get the HTT up to about 330 MHz using ClockGen but 1 or 2 MHz more than that and it would lock up solid.

Good board but the DFI is definitely the HTT MHz king. I've heard of other users hitting 350x8 = 2800 MHz with their Sempron64 2800 chips on the DFI nForce3 board.

Agreed. Hours of playing around and I found it very hard to get it stable in the 2.7ghz zone, and that only at 1.65v (my board runs a little voltage high, so it's probably a bit more than that - sometimes it read almost 1.7v). I topped out at 1.682ghz @ 1.55 (what I run now) and ~1.6ghz @ 1.5v.

Agreed, my Gigabyte K8NE flakes out at any HTT over 330*1x (sometimes I can stabilize it at 1.5x HTT). Very finicky.

very low speeds ? :p

In my case, prime95 failed at the same place as before so it's definitely capped so i will try to find some modded bios or someone with the ability to mod it so i can run over the cap :mad:

Come on now, we can't be too sad that we can "only" overclock our HTT by 65%. :D

I had an Asus board and they capped the HTT at 250 MHz. Now that was sad.

With the majority of processors with multipliers from 9X to 12X, an HTT of 330 MHz will not hold you back from getting the most out of your CPU. With an 8X multi like on my old Sempron64 2600 it would have been nice if I could have pushed it a little harder but most people are quite happy when their 1600 MHz processor becomes a 2600 MHz ( 325X8 ) processor with just a simple tweak or two.
 
My ram is 400MHZ ram. So when I run my FSB anything less than 250MHz I am running it less than spec and this bothers me. I currently have it at like 220 or something, but would I be better off lowering the HT multi and raising the Ram to a full 400MHz or does this not have much affect on these systems. I am comming from a Barton that loved memory bandwidth.
 
Is this a pretty decent overclock??

The whole reason I pushed it as far as I did was I installed a 1GB stick today along with my old 512MB stick (1GB replaced another 512MB) and my Biostar NF325-A7 started to force memory speed to DDR333 even though both sticks installed were DDR400.

Anyways, I was in a quest to make my memory run in spec so using ClockGen I:

(BTW: This is a Venice 3400+ 512K)

- HTT: 3x250
- Voltage: 1.5v (Not even sure how much is required, I'll back it down once I know it's stable here, 1.40 was stable with 2507MHz)
- CPU Multiplier 10.5

It comes out to 2.63GHz with my DDR running at DDR404 3-3-3-8 2T


Seems very stable so far, idles at 34c and load doesn't crack 50c. I've ran Sandra burn-in for 30 minutes, played FEAR for an hour and ran a little Orthos. I'm about to leave for about an hour so I'm going to rerun Orthos while I leave.


Overall, is this pretty decent? Do you think more could be achieved? (This RAM is known to run at least at 209MHz)
