Intel Core i7-3820 & Intel DX9T0 Extreme Series overclocking issues.

post #1 of 5
Thread Starter 
Hi, this my first attempt at overclocking and I have read the guide for the Sandy Bridge-E architecture and various i7-3820 guides.

I seem to be unable to achieve a stable overclock with Prime95 making my system blue-screen when I manage to boot. My goal is to achieve a stable 24/7 overclock at 4.6GHz if possible without exceeding 1.35v so my chip doesn't degrade.

The first way I approached this was by using a low Multiplier around x36 and using a higher Bus Speed. The reason for this was that I was reading how a higher Bus Speed will result in better performance as the CPU's I/O is higher, the Issue here was that for some reason the changes that showed in the BIOS did not take effect once fully booted, CPU-Z would only show the default voltage and Bus Speed with a the correct multiplier of x36, which brought my Core Speed down to 3.6GHz.

The second method I tried was keeping the Bus Speed at 100MHz and setting the multiplier to x46, but wait - the BIOS will only let me set the multiplier to a max of x44, which brings me to 4.4GHz, not exactly my goal.

Then I tried reaching 4.6GHz by setting the multiplier to x44 and the Bus Speed to some 100+ish to reach 4.6GHz, only to not boot.
(I tried all above OC's with a 1.35v)

So any ideas what I could do, any help would be appreciated? I will list my BIOS settings/possibilities:

Host Clock Frequency (MHz)
Host Clock Multiplier <1.00, 1.25, 1.61>

Processor Voltage Override (V)
Processor Voltage Droop Control

Intel Turbo Boost Technology
TDC Current Limit Override (AMPS)
Burst Mode Power Limit (Watts)
Sustained Mode TIme (Seconds)
Sustained Mode Power Limit (Watts)
Voltage Offset (mV)
Runtime Turbo Ratio

4-Core Turbo Ratio
3-Core Turbo Ratio
2-Core Turbo Ratio
1-Core Turbo Ratio

Maximum Non-Turbo Ratio

What is the highest stable overclock you have reached so far with each method?

Nothing really, accept the first time I used the BIOS's automatic overclock helper which had me at 4.2GHz.

Haven't you tried finding your highest stable overclock? You may have a bad chip, some are like that. All CPU overclocking limits are CPU specific.

Well I don't know how to reach a stable clock. Either the settings wont take effect once booted into the OS or it won't boot at all.
That's why I'm here, hoping someone would throw some numbers at me.
