Trying to get passed 4.5 GHz

post #1 of 5
Thread Starter 
Hey forum

Alright so after having my OC at 4.5 GHz for some time now I would like to go higher but can't get it stable.

So what I have done so far is:

Disable:

Limit CPUID Maximum
Power Technology
C1E Support
OverSpeed Protection
Spread Spectrum
HT (Lower temps and voltage)

Enable:

Internal PLL Overvoltage
Execute Disable Bit
Intel Virtualization Tech
Low Vdroop

Latest Bios update.

I was aiming at 4.7 GHz and was "stable" for 5-6 hours and then it BSOD. So I just bumped up the voltage twice and after just browsing the web I got a BSOD after 10 min. So I thought it might be my RAM but everything else is at Auto so it "should" not BSOD but I might be wrong.

Voltage used at 4.7 GHz was 1.392V at load and 1.35V at idle.

And tip on what I should do?

Many Regards

Most of the time is it's RAM related you won't see any BSOD. Your system would just hang up.

Did you use any stress program in order to check for stability ?

here what I recommend :

1. Get Memtest+ and test your ram for at the least 3 passes
2. Download Prime95, LinX or Intel Burn Test
3. Set your BIOS to match your 4,5Ghz
4. Make 20 runs LinX and confirm you are stable
5. Set your BIOS to 4.7Ghz
6. Make 20 runs of LinX to check for stability
7. If fail, bump Vcore a notch and retry
8. Do so until you hit stability or heat issue
9. Run an overnight blend test on Prime95
10. If fail, run Prime 95 small FFT (this would stress "only" the CPU so you would know that your Vcore is enough) overnight
11. if fail, bump Vcore and do so until stability or heat issue
12. Run Prime 95 blend test overnight

I ran Prime95 for some time with no errors.

I havent tested memtest yet but I will, I knew I forgot something

It matches the current settings. All I did was turn off HT, enable Vdroop and bump up the voltage all the other settings are Auto.

I will try running Linx

Thanks for the info

Set VRM freq to 350,
PHase control to Extreme (not sure what this is in MSI boards)
LLC to Ultra high
Enable everything u disabled except Spread spectrum

Set vcore in BIOS to 1.31v an Turbo multiplier to 47 an now see.

I don't have any options for Phase Control or LLC.

I have Vdroop on tho.

I need atleast 1.338V for 4.5 GHz and about 1.4V for 4.6 GHz so I can't see why 1.31V would work then.
