Ah so this is the issue I am having...
At idle it stays at 4.1ghz
under max load (intel burn test, prime95, I believe gaming as well) the cpu speed goes from 4.1ghz to 2.2ghz.
This would be a definite reason as to why I am seeing low benches. goign to bring it back aroudn to stock since I am running the vcore very high.
I basically was following the i7-930 guide
http://www.overclock.net/t/538439/guide-to-overclocking-the-core-i7-920-or-930-to-4-0ghz/0_70Method #1: Optimizing for max performance per watt. (Click to show)
This method takes by far the most amount of time but for many its worth it in terms of its power efficiency.
Begin by going into the bios and changing your voltage to your vid and setting qpi/uncore (vtt) to 1.25 (I have raised this due to concerns about droop at 1.2) and vdimm to 1.65 (Most boards can't do this 1.66 is safe, ignore your spaz bios warnings; you are not going to explode anything, although if you do, it's not my fault. Set it to 1.64 if it helps you sleep easier. I recommend at this point to be working with either the 21x multiplier if possible in order to keep your ram as much out of the equation as possible. 20X has known problems and 19x will land you with high ram speeds quicker which will require raises in the qpi/uncore voltage sooner.
Open up real temp and run prime 95 with 8 threads and check stability for an hour at least (The more the better. I recommend overnight just to make sure all is good). Record your settings on a piece of paper or email them to yourself. Make sure to have realtemp open in order to watch your temperatures. Temperatures should not exceed 80-85 during prime. During normal use for extended periods, they should never see these kinds of temperatures. I like to keep mine below 70 for normal usage.
After its stable go into the bios and increase the bclk by 10 and repeat the process. Find the max bclk for your stock vid (or any voltage, if you'd like by lowering by smaller amounts when you find an unstable clock. This will help you know what you can run at any given voltage.
See below for known prime 95 errors and how they relate to your settings (also some settings to try for stability). Once you get to the clocks you want, I recommend running prime for at least 16-24 hours. I have in fact had errors in the 14th hour so it's good to know that you're truly stable.
See also below for optimizing your ram settings.
Will Lower the VDimms and see if it makes a difference
EDIT: Lower lowered my Vcore from my 1.65 test to 1.35 and QPI/VTT to 1.315
Loading intel burn test and right now it reads:
Core @ 4.1ghz multi @ 23 temps are between 59-60C
So it seems that even though EIST and C3 is shut off that it still thermal throttles the CPU at the high rates. It will boot into windows fine so how are we to find the max clock?Kana
I have the multi set to 23 do you want me to move the BLCK to 187 for a 4.3ghz setup and start there?EDIT2:
Loaded with your settings Kana
However my QPI Link Speed is only 6.73GHz not the 7.2 you wanted
Then Uncore is set to x18 which ggives an Uncore Clock Ratio of 3666MHZ
Running Intel Burn test and Prime 95 together and Temps are ranging between 68-70C on Maximum Load.Edit
got error 003b and prime 95 shut off 2x going to raise VcoreEdited by dpoverlord - 3/4/14 at 6:45pm
