OC E6750 problem

[Abraksas]

Hi to all I am new here, and I really like this forum.

I have stock cooler on my E6750 and I overclocked it to 3.2 GHz FSB 400 MHz , my Vcore is set to 1.32 but it shows 1.3 on my Asus P5K-E system is running very cool Core Temp is showing Core#0 >44 Core#1 >45 when I run Orthos. Oh yes my memory = 2 x 1GB Kingston 800Mhz and FSB:RAM is 1:1 PCIe frequency is 100 MHz

Problem: after 20 min of using Orthos he pop error "FATAL ERROR: Rounding was 0.4965820313, expected less than 0.4" so it indicate that the OC failed but my system is still running stable after 2 hours of Colin DIRT torture :)

maybe my power supply is 2 weak ( Spire 315W ) I would like to hear some suggestions if there are any :) thanks in advance

Bump up the Vcore a notch, and retest.

I will try to increase Vcore voltage some more but how high I can go I know there are limits :)

depends on your cpu and motherboard fsb and also what your mem can handle ... for me i know mb fsb wall is at around 515-520, cpu does 490x8 with mem 1:1 so its at 980mhz (mem isn't stable after that).... also cooling comes in to play aswell (got the system a bit more stable with nb fan) .... most ppl agree that the new core temp reads correctly with these chips at tjunction 100.

I don't know how much you vdroop on your board but you should be able to increase your voltage to 1.35Vcore (actual) considering you are on stock air ... alot of ppl avg around >3.5ghz with good air cooler and a bit over >4.0ghz with H20 with these chips (ofcourse depending how lucky you are with the chip).

With me 1.35Vcore actual got me around 3.5ghz orthos small + blend 24hrs stable

tnx jae, new cooler and new PSU is coming so I will post so I will post results. I can't go over 1.30 even if I set up 1.35 so with new PSU .... I hope ... :)

Stable with 1.35 so far 2 hours of orthos small + blend test but this stock cooler is VERY LOUD so I am waiting for my new Spire Fourier III
