still running orthos, E8400 at 4.1GHz with 1.3vcore in BIOS

b-star · 3 Jan 2009 at 16:30

i reduced from 4.2ghz to 4ghz on air, seems like everything is stable untill i start to play high end games: crysis, Cod4, dead space, prince of persia, etc...games or crash, loading more than 20min, etc ...so system i guess not stable

ehis is my bios:

any suggestions to improve performance and get stable system?

i tried different voltages, GTL, etc. but it doesn't help

i would like to get 4ghz stable...or 3.8ghz in case...

Thanks GURUsun, i will try ...

nope, system is not booting gurusun

How is your over clocking going b-star?

Descent · 4 Jan 2009 at 10:11

As soon as I get my new PSU tommorow, I'm going to see what I can do with the core contact freezer.

well, i went to 4.2ghz on air... the temperature was a bit high, so i dropped to 3.8ghz for now, till i get a new CPU cooler!

3.8ghz is stable even when everything on AUTO, till i play crysis, prince of persia...

started to play with bios, stable, even crysis runs great on maximum, but prince of persia lagging a bit, so something still not perfetimo

i use gurusans BIOS SETTING which he posted, but fsb 400 (for 3.8ghz)

will drop voltages today...will see after

gurusan · 4 Jan 2009 at 13:00

What is your exact memory brand and model?

b-star · 4 Jan 2009 at 13:11

RAM:

OCZ (4x1GB) PC2-6400C4 Dual Channel Platinum Revision 2 XTC Series DDR2 (OCZ2P800R22GK)

rapid64k · 4 Jan 2009 at 20:35

Ran the OCCT test for one hour stable. Icant seem to get the image bigger!

b-star · 4 Jan 2009 at 21:06

so you have the same CO E8500 and 3.8ghz?

can you post your BIOS?

thanks

what would you recommend to change?

rapid64k · 4 Jan 2009 at 22:18

What type of ram do you? would be good to see what they run at? Also try increaseing NB FSB to around 1.45.
CPU PLL I think its a wee bit too high either set it to auto or bring it slightly above the cpu voltage.

Memory:
OCZ (4x1GB) PC2-6400C4 Dual Channel Platinum Revision 2 XTC Series DDR2 (OCZ2P800R22GK)

you mean NB VOLTAGE TO 1.45?

which Cpu volt you have?

did you try to push till 4ghz?

Sorry, I know you are just trying to help... but he has a P5Q mobo which is based on an entirely different chipset, most of the settings from your board aren't relevant. For example 1.45V is waaay to high....1.3V gives me almost 533fsb.

b-star, the mobo settings I've recommended should get you to 4ghz. I think that the memory settings are holding you back since you say you cannot boot....try my recommended settings with memory voltage at 2.1V, and all memory timings on auto

rapid64k · 4 Jan 2009 at 23:21

oh well.
