CPU o/c fine , games crash like crazy

Bald-Eagle22 · 23 Jun 2007 at 20:15

Guys

I can o/c upto 3.1 quite easily but anytime I play a game I crash like mad .

I have taken the O/C down a lot now and I play BF2 for 10 mins and crash to desktop .

Help ??

You running bf in vista or xp?

Only other thing I can think of is that the HSF isn't seated properly so your cpu is overheating when under load, such as in games. Have you run Orthos and Speedfan to check the temps?

Edit: just noticed screenshot :rolleyes:

mine was the same, 3.2 and only crashed in BF2142, its a non completely stable OC, try clock and see if it crashes.

Use Orthos for stress testing. Prime only stresses 1 core I believe.

Would depend on the version, the newest releases support multi-core when only running one instance.

How long should i run Orthos for ?

paradigm · 23 Jun 2007 at 22:21

Minimum of 5 hours, most swear by 8+ hours for guarenteed stability.

Have you tryed loading both cpu cores with TAT ????

Plus: Why you only running your memory at 300mhz :confused:

Try putting a little bit more voltage on your RAM, if it allows for it

Bald-Eagle22 · 24 Jun 2007 at 00:23

Ok a few more screenies for you all here as I am absolultley stumped on this .

E6600 Conroe (D TEK WATERCOOLED)
4x1GB of OCZ Plat rev 2 PC2-6400C4 Dual Channel Platinum Revision 2 XTC Series DDR2
EVGA 680i P28 BIOS
WINDOWS XP
BFG 8800GTX (DANGER DEN WATERCOOLED)
LAING D5 PUMP
DANGERDEN BLACK ICE2 EXTREME 120.2 RAD
4X120MM SILENT EAGLES
2X80MM SILENT EAGLES

I have left it at a very mild O/C for the time being , my Bios is the latest for my EVGA 680I board .

Everything runs fine except i keep crAshing in BF2 at the end of a round or during a map load .

Sorry should have told you I am a complete NOOB , Vmch can you explain a litttle more please ?

Lydzor · 24 Jun 2007 at 01:49

I believe vmch is the voltage of the northbridge.

furnace · 24 Jun 2007 at 11:31

Your memory's running at 1.85 volts - if this is your memory;

http://www.ocztechnology.com/products/memory/ocz_ddr2_pc2_6400_platinum_revision_2

It's supposed to run with 1.9 - 2.1 Volts (so say 2.0 volts).

It might not be the problem (it was the problem on my mates pc in the same situation though) but at least you'll know you have your RAM on the right voltage so you can take that out of the equation

Also you wanna get your FSB:Memory ratio off 'sync mode', which I gather is a 1:1 ratio, and onto something like 'x1.33 multiplier', which would be 3:4 ratio. So your FSB at 300Mhz would then run your ram at ~400Mhz (which is what PC2-6400 ram is supposed to run at).

yeah do the memory one first

, but the Vmch i would say will be another problem as it was mine too. After i upped it games ran really smoothly for hours.

Any ideas what a good Northbridge voltage would be ?

shimy182 · 24 Jun 2007 at 12:59

oh geez i forgot what mines at, something like 1.4v onwards? can someone else confirm this?

furnace · 24 Jun 2007 at 13:09

I'd just stick another 0.1v or 0.2v on, and see if it makes any difference
