C1E should be set to Enabled just to be sure that it's always working.

LLC should be set to a value that minimizes vDroop the most without getting any vRise (no spikes).
EDIT #2: !?!?!?!, all that time I spent playing in the BIOS and when checking the number of threads the stress test was using in the preferences section I noticed it said 1! That should of course be 4, everything back to normal and working. C3 and C6 states are disabled, C1E is enabled, Package C State Support is set to C2, spread spectrum is disabled to give me 100.0MHz without changing the bus manually to compensate.

ORIGINAL: Well after some playing around with C states this morning and taking some advice from another source about spread spectrum being disabled, I thought I'd quickly try it, eurgh something just made my gflops go rubbish (16~ compared to 60+~). I'll try disabling Package C State Support again and see what the results are, failing that I'll re-enable it again and also enable spread spectrum and see the results then.

Additionally disabling spread spectrum gives me a nice 100.0MHz number on the bus without having to set 100.2MHz now. One can only learn the different effects from trial and error I guess.

EDIT: Changing those made no difference, still 16 gflops. The only differences remaining are the C3 and C6 states being disabled and the loadline and vcore settings being different, none of which (except C states) I can see effecting the gflops performance this badly. I'll revert back to my previous overclocking profile to be certain that still produces the gflops I remembered seeing. The power usage has also dropped by around half when the processor is under load (about 50W now) and as such the temperatures are much lower too, very wrong.

Ixel,

What is GFLOPS? Is that the Intel Burn Test?

I suppose so, gflops are gigaflops (floating point operations per second), I used LinX to get that result though, that uses the Linpack stuff which IBT should too, so yeah. I'm trying to get a 4.7GHz clock on 1.34-1.36v vcore currently, will update if I manage to get a stable clock under 1.40v maximum. Currently testing on a fluctuation vcore of 1.33v-1.35v.

I've found adjusting the additional turbo voltage (mV) setting in the BIOS is helping improve stability rather than vcore offset like I was previously. Adjusting the ATV (mV) also increases the idle voltage accordingly, so it's not too low at times when idle and BSOD or freeze may occur. Will update more on that soon, previously I left it at auto or +0.004v. Also I am able to adjust the voltage with slightly finer precision as it's increment options are 0.004 apart.

I sure wish we had the same MOBO, either way I will look into the settings and I am going to find LinX program, if you have a link - post it please.

I wil lgo look through the BIOS to check these voltages and the ATV

I see. This should be the link to getting LinX without AVX support (LinX using AVX is bad for stability testing from my experience, just a great heater lol), http://www.xtremesystems.org/forums/...pack-interface.

After further testing I've found ATV doesn't increase the idle voltage by much more than .008v, so mine for example is 1.008v. However it has been a better result for me than using offset voltage adjustments, I've now set offset voltage to +0.005v and altered the additional turbo voltage only, as some increments are +0.003v and some are +0.004v which means finer precision on a nice and close voltage.

My preferences were 5 runs at 1024M.

It runs solid like a rock so far I'd say?

I started off at 25 degrees ---- the temps went up as you can see in the HWMonitor.


I really want to try and get to the next level x46

What should my next move be? What do you think?

That's a low vcore on that screenshot, way less than mine, mind you I'm trying 4.7GHz lol, either that or I have not got a brilliant CPU . LinX isn't the best for stability testing however, many go by Prime95, however I prefer a mix of OCCT for the first 30 minutes on medium dataset, and if that passes, another 30-60 minutes of Prime95 for a quick stability test, of course, time isn't really a definite factor in how to determine if your configuration is stable. I'm not sure what your next move should be, but as I say, I'm still trying 4.7GHz until I'm either at a point of uncomfortable voltages (1.40v VCORE is my limit) or temperatures (80C maximum core temperature under stress).
