i7 930 4.0ghz Milestone

post #1 of 23
Thread Starter 
after 2 days of hard tunning i have reach 4ghz on my i7 930 with the folowing settings:
Cpu V core-1.29375 my cpu-z report-1.330
VTT-1.36250
Cpu Dif Amplitude-900MV
IOH V-1.2
ICH V-1.2
Cpu clock skew-100ps
Ioh clock skew-100ps
PLL-1.8
LLC(load line calibration)-enable
Dram bus voltage-1.6
DDR timings-7.8.7.20

these settings have been tested with linX 1h-stable and Prime 95 Large FTT's

The problem is that if i lower the Vcore or VTT i get BSOD 101 or 124.........i just want to lower my Vcore but i can't some advices........

Do a CPU-Z Verification for us so we can have a look biggrin.gif

CPU-z validation?

With that much Vcore I assume you have HT enabled.

congratzz, because it took me awhile to go from 3.8 to 4.0

Not that i tried many BIOS settings but I was happy with 3,8 and after using only 3 settings I was satisfied with the outcome.

I ended up with 4cores 4threads, offset Vcore, 191bclck with 21 multiplier ...

My temps are a tad bit below 70*C and happy with it. Your should be definately lower since you have better cooler.

yes my ht is on....i want less heat but as i said if i lower my Vcore or my VTT i get BSOD........there is no solution ???my chip is not that good.....???

Hyperthreading is holding you back from lowering the voltages so you should be just fine but temps are a bit of concern - reaching 80*C after only hour of prime.

I recommend using 21 multiplier and 191 BClck in Bios cos it somehow offers greater stability.

I think you should be fine with the settings as it is unless you are willing to ditch HT but I assume this is useful for your purposes.

yep i don't want to ditch my HT so...if i put my multi at 21 and BClck at 191 i can lower my CPu v core???my max temp was 78C..is a bad temp?

78*C is not a bad temp but to be on a safe side I don´t recommend seeing it past 80*C at any given moment to avoid degrading your CPU in longer terms and I am afraid you may see higher temps with Prime 95 blend for 18-24 hours if you TRULY want to test stability of your components.

I don´t know if you run your PC under full load for 24/7 (heavy encoding, programming, folding perhaps?)

If your cores don´t run actively (let´s say 70-80% usage over longer periods of time) then you should be just fine skipping along with temps such as 50-60*C

Changing the baseclock and multiplier will not guarantee a possibility of lower Vcore, but it doesn´t do harm to try. Should give better stability with current settings as is.

Then you won´t benefit much (if at all) from hyperthreading enabled and I suggest you disable it to see much lover voltages in general and lower temps in turn since your GPU is a bottleneck (a minor but still) in your system anyway in your sig rig.
