2500+ OC

[Bosse]

Been quite some time since i last tried to oc my 2500+, i ran it at 11x200 and it handled prime95 hour after hour but when i played games i got some form of bluescreen after +30min even @ 9x200 i tryed raise vcore some but still same problem, now im thinking of trying again, anyone know what the he11 i should do to make it work at 11x200 ???

What revision is your mobo? It could be that it can't handle the higher bus speed perhaps? Or maybe your RAM needs looser timings, although I have that stuff and it's running happily with extremely tight timings on my rig.

So, what are your RAM timings, and what Vcore have you tried it at so far?

Try 190x11.5 or something, just to see if it's the bus speed or the actual CPU speed that's the problem.

its rev 2, i dont remember what vcore i tried but i think i tried what was max recommended, what timings should i use ?

What's Vcore at?

Just try nice relaxed timings. something like 3-4-4-7 maybe.

As far as Vcore goes, if your barton needs more than 1.8V To get 2200Mhz then you've got a bit of a lemon :frown:

I would say that with <i>good</i> air cooling, Vcore could go as high as 1.85V fairly safely, but that's going to be a bit on the warm side for sure.

1.85's a little high, especially on Asus mobo which overvolts that to about 1.93

Your ram oughtta handle FSB 200 w/o breaking a sweat. Gee, it's 3200LL prolly using cas2.0

Set it to spd "optimal" or whatever your mobo calls the stable setting and run memtest86 to make sure it's OK.

I'm thinking it's your cpu (some just don't like FSB 200, mine doesn't) or some BIOS may need tweaking to attain stability.

Here's a forum for ur specific mobo, see if there's any BIOS tweaks etc. you should be doing <A HREF="http://www.nforcershq.com/forum/viewforum.php?f=13" target="_new">http://www.nforcershq.com/forum/viewforum.php?f=13</A>

Good Luck with it.

hmm i think i will try 11*200 at orginal vcore 1.65v and relax the timings a little to begin with.

[scottchen]

It won't work, your ram's not the problem, it's your Vcore. You'll need at least 1.75, 1.8 is probably required for stability.

now i run 11*200 with 1.65v and 2-2-3-5 now i have to try play games and see if (or when :C) i get bluescreen. its a same if i cant get it to work its so darn fast @ 3200+

1 wierd thing is : it doesnt boot with 3-4-4-7

Do some kind of stress testing, prime95, super pi. And see if your CPU fails.

i have ran prime95 4 a day before np only things that [-peep-] up is games

Now after 30 mins of warcraft:


Fatal error

[scottchen]

if your PC survives P95, then the CPU/mobo/ram's fine, so video card. Check see if it's overheating.

Do you run WC3 in solo or over the internet?

I know that WC3 is more prone to crash with overclocking, this was the only game that crashed on my system, but with the latest patch of the games it never crashed again.

I have WC3 : TFT and I play on battle.net, so I have the latest version of the game.

hmm why should videocard overheat ? u dont think vcore is the problem any longer?

[scottchen]

You said it's stable in Prime95, that's one of the most torturous tests out there, so it's either the vid card or software problem.

[StarScre4m]

Use a temp monitor and check the vid card and the cpu temps under load.

 

[Bosse]

hmm i raised to 1.75 anyway and so far so good. only problem now is everytime i restart comp and look at startmenu it says almost all my progs has just been installed ??? thats wierd !!! well i try play some more and let u know later if it keep stable.

BTW Scottchen maybe war3 is better test prog than prime ^^

WC3's one of the most non-stressful games.

[Crashman]

Not so unexplainable. He might need to raise vDIMM. PC3200LL doesn't always operate stabley at the rated settings, stock voltage, dual channel mode.

[Crashman]

I don't know what your board supports, but 2.7v should do the trick.

Download Motherboard Monitor 5 and check the vdimm, or voltage to your ram. <A HREF="http://mbm.livewiredev.com/" target="_new">http://mbm.livewiredev.com/</A>

While the Nf7-S overvolts ram, and undervolts cpu. I think I remember reading your mobo undervolts ram. MBM5 will tell. If it does undervolt ram, just increase it to stock or a little more (till it can pass memtest86 mentioned below).

Also, if your pc can Prime95 torture test, you cpu ain't the problem. (No need to increase voltage) Rather d/l and run memtes86 to check the stability of your ram. Get it here <A HREF="http://www.memtest86.com/#commands" target="_new">http://www.memtest86.com/#commands</A>

EDIT: Stock/or recommeded vdimm is 2.6, but the ram can, and in some cases likes more. Although that's mostly for OCing. The NF7 series likes tmings of 2-2-2-11 best for some unknown reason. The 3200LL I have can run as tight as 2-2-2-5, but this mobo likes "11" better. Go to nForcersHQ and check what everybody with your mobo is having the best luck with as far as timings go <A HREF="http://www.nforcershq.com/forum/viewforum.php?f=13" target="_new">http://www.nforcershq.com/forum/viewforum.php?f=13</A>

WAIT! I just noticed your vid card is a G3 Ti200. How old is that? Have you clean out the fan lately? Overheating maybe? If you can pass Prime95 and memtest86, and your freezing etc on games. Look to the vid card
