yeah running the FE bios and it did an 8.5hours OCCT test without errors last night, and have been using it the past 2 days so i am happy its pretty stable. will have a play with the ram settings when i get chance.
4GHz i7 920 D0, but only on 19x

Code:
CPU Clok ratio 19x
QPI Link speed x36 (7.2GHz)
Baseclock 211
Performance Enhance - standard
XMP disabled
System memory multiplyer SPD - 6.0
intel turbo boost - disabled
Cpu cores enabled - all
CPU multithreading - enabled
C1e , C3/c6/c7, thermal, EIST and PROCHOT all disabled
Virtualization - enabled.
Uncore freqency x13
Isochronous supprot - enabled
PCI frequency - 100
CIAZ -disabled
CPU clockdrive 800Mv
PIC Express clock drive 900Mc
CPU cliock skew 100ps
IOH clock skew 0ps
Local-line calibration - disabled
CPU Vcore 1.250V
QPI/VTT coltage 1.295v
IOH Core 1.16V
DRAM Voltage 1.640v
everthing else is as at default / autois there anything i can easily tweak to get better performance as this is the best way i have got 4GHz stable. is running at 19x slowing the total oc down?
anyone?
is there a way on this mobo to have the fans on full speed perminantly?
are my skew and clock drive settings ok, or can i improve them? (is lower better?)
also, do i need to change the qpi link speed if i change to x21 multiplier?

everthing else is as at default / autoright managed to get the ram up a bit, its also now set to 9-9-9-24-2 is this ok or is it worth seeing if i can lower them a little bit?
is this an ok score for the settings i have chosen?
is this an ok score for the settings i have chosen?
Seem OK My system 4.0Ghz passMark Rating is 2777.6 (19x212)
If I up my system to 4.2ghz passMark Rating is 3080.0 (21x200)
My score is higher in the memory and disk tests in the other tests my score is similar to yours

you got better (more) ram than me, and the ssd will help so overall cant be too bad i guess. just wish i new more about ram timings, qpi, clockdrives and stuff to see if i can get more out of it. i have a stable 4GHz so now just need help in tweaking the settings that i may of got wrong to get the most i can out of what i have.
yeah, not sure whats best to change it to.
changed them to 8-8-8-20-1 as thats what the bios suggested they should be. does that seem about as low as i can go?
Those settings look just fine with the memory running at 1600Mhz +.

ok kool, well so far everything seems stable with these settings, so will see how it goes.
are there any other settings i could do with tweaking? cant seem to get it stable if i lower the vcore to 1.281v, havent tried 1.28* or 1.29v yet though.
What vcore are you using now?
From the settings I have seen on the last page all are very similar to mine.
I have to use a system memory multiplier of 6.0 as I using 12GB, but I can get some of the performance back by using 6,6,614,1T timings.
What programs are you using to check stability?
What are your temperature like with full load?

back up to 1.300v vcore.
use memtest86+ to make sure the ram is ok and OCCT for the cpu.
full load is 76-78deg

yeah i am reasonably happy with it, would prefer to get the temps down a degree or 2 but cant complain. have only done an 8.5hours OCCT run on it, and out of that 8 hours probably ony 50-60% of it it was on the highest temp, most of the time it was 71-73deg.
the thing im worried about is the clock drive settings and QPI stuff, not sure if i can tighten them up to get better use out of the 4GHz clock.

You have your QPI Clock Ration [x36] which is the lowest it will go.
Your Uncore Clock Ratio is set to [x16] which is OK
The rule is that uncore should be 2x the memory setting, some people add 1 and go with 17
From what I have read that the QPI It's how the CPU and the x58 chipset communicate (It has multipliers of 18x, 22x, and 24x). The 920 should be left at 18x (x36 on Gigabyte boards) creating a 9:8 ratio between the uncore and the memory multiplier assuming you use the 8x ratio, which some claim offers the greatest stability.
As for clock drive settings, you can try lower settings.
I am using
CPU Clock Drive [ 700mV]
PCI Express Clock Drive [700mV]
CPU Clock Skew [ 0ps]
IOH Clock Skew [ 0ps]
But not all chips and motherboards are made the same. My setting may not work for you.
Most important be methodical in testing settings since you want to know whether something helped or hurt by itself before you combine.
You have your chip to 4.0Ghz now, do not worry about the clock drive settings and QPI stuff.
Start to have some fun and confirm that the system is fully stable by playing some games

been using it on 4GHz for a few days now without issues, just the ram i have altered today. doing some benchmarks now to see how it compairs.
