General discussion

how to stabilize an OverClocked sytem

Apr 11, 2011 3:29AM PDT

Dear community,

I have recently started overclocking my system. I am using "Prime95" as my stress testing apps, Cpu-z and Cpuid hardware monitor as my monitoring tools. I have managed to clock the system to 3256.6 Mhz(ideally I would like to clock to 3.5-3.6 Ghz) but I can't seem to stabilize it. I have increased the CPU, NB, SB-Volt, decrease the Htlink multiplier and the link self(seen under the CPU-Z screen), and decreased the memory divider.

Here are some of the numbers I have pull out from the Bios, Cpu-Z:
Core volt: 1.409(dare not go higher than this voltage.)
Bus speed: 250.5 Mhz
Multiplier: X13
NB volt: 1.200
SB volt: 1.200
Dram volt: 1.63
HT Link: 2004.1 Mhz (decreased to this final setting)
Decrease memory divider: 1: 2
Core temp: 38o C - 51o C
Error message from Prime95: "Fatal error-rounding was 0.5 expect less than 0.4 hardware failure detected, consult stress.txt file."

I am using "Prime95"to test my system, as test type I am using "small ffts" and "bit of everything". I have also notice that a test fail immediately(within 1 minute) or at the 11 minute mark. Another thing I've notice is worker #4 (in Prime95) is the one that always fail(does that mean it is not getting enough voltage for all four workers?).

If there is anyone out there in the community that may have a suggestion(s) on what I can try to stabilize the system and/ or can explain what the Error Message means(does it give an indication as to what needs to done or where to go and how to fix the problem-that sort of thing), why only worker #4 seem to fail and the test failing at a specific interval in time. please feel free post the suggestion(s) on the forum or contact me at carbonbase_lifeform@hotmail.com.

I sincerely thank all participants in this forum for your help.

What I found

When you OC, you're pushing your system. The best setup will have increased cooling and stable PSU or capable one. The OC level you reach will be very dependent on those factors, cooling and power. Once, a stable level is meant, increased pushing further will only succeed in a fault or reboot. If your cooling is "air", then consider a water based cooling setup to get into other levels.

It's much easier ...

to buy a faster CPU than to overclock one to make it somewhat faster. So I consider overclocking as a hobby more than a necessity. Keep on experimenting.

Sorry, not very helpful, I think.

Yep, I agree

If I need to go get that loaf of bread in 1/2 the time it currently takes, I trade the old Volvo for a Maserati rather than buying a supercharger for it.
