Try editing the runme_xeon64.bat file to this (or make a new batch file):
Code:
@echo off
SETLOCAL

rem Setting up affinity for better threading performance
set KMP_AFFINITY=nowarnings,compact,granularity=fine
rem Setting path to OpenMP library
set PATH=..\..\..\redist\intel64\compiler;%PATH%

echo Running linpack_xeon64.exe. Output can be found in win_xeon64.txt.
start /b /affinity 55 linpack_xeon64.exe lininput_xeon64 > win_xeon64.txt

echo.
echo When this window closes the calculation is done.

ENDLOCAL


That sets the affinity for 4 cores (basically turning off hyperthreading) and lets it run one thread per core like Intel recommends. 4 core/4 thread should give you something above 200 GFlops and makes it run hotter than the normal batch file (which screws up with hyperthreading on). It'll run for 15 minutes or so, then the command window will close and you can check the results in the results file it makes in the folder.

End of tests


yea as I understand the issue with AVX/AVX2 adding voltage is only with adaptive voltage like with asus boards. Gigabyte i dont think has adaptive and you just use manual voltage. As I understand, using manual voltage on gigabyte is exactly identical to using offset in the past, and I'm using manual voltage.

Thanks for the info, I made it to test 35000 before I stopped it since I didn't know if it'd continue or stop eventually and i had to go to bed. I can't imagine it's better for stability testing to run without hyperthreading, i mean that really increases the load on the system, no? Anyways, making it to the 2nd to last run just fine, but I had a HW Error in P95 in 4 minutes, so unless turning off hyperthreading is better for total system stability testing, I'm going to stick with 24 hours of prime95.

I tend to get HW errors in p95 (ie worker stops, FATAL ERROR hardware error rounding was less than ...) due to unstable RAM timings, and right now I'm working on tweaking my final tertiary timings. Tertiaries are such a pain to get stable, but they tend to give the biggest performance boost besides like cas and mhz. I gained over 400 copy tightening just a couple tertiaries. Of course maybe that isn't stable, so we'll see.

How stable is it? Depending on how stable it is, that could either be so what to holy crap. I would imagine most chips can validate 5.1@1.45

I guess soe have to copy and paste the dll to that folder where the bat is located. The dll on the other hand is few directories back, search it.

Do you guess? I located where it was, and I can run the bat just fine. But I can do this if it's necessary, just when you say 'i guess' doesn't strike confidence in me ;/

CPU-z 1.64 and hwinfo report 1v being increased to ~1.08, but it gets hotter than 1.2-1.25v, no idea how that's possible

I would like to know too !!

Did You try raising Vrin lets say 1.9 and Vring 1.2 together with LLC extreme ?

I have a bad I5 4670K and when I go 4,4 GHZ it wants 1,9 V Vrin, 1,2 Vring and 1,34v Vcore. good but not 100% sure
4,3 GHZ 1,85 1,15 1,25 all stable Battlefield cinebench Handbrake etc.

Question :
If I set In Bios 1,34v then I get with Prime 1,365v would that be Vdroob ?
Or is The Sytem / Prime giving more Vcore ?

1.34vcore sounds a lot for 4.4Ghz but I suspect my CPU also needs the same just for 4.4 , what temps are you getting with those kinds of vcore? I am hitting instant throttle with just 1.300.

Also, turning off Virtualization, my BCLK went from 93-94 to 99, and turning off C states BCLK is solid 100Mhz now biggrin.gif Fingers crossed tonite to complete 8h OCCT and then start to lower voltages.

About your question, with LLC at extreme you should have a really low vdroop, what you see with your Vcore raising with Prime is a feature of the cpu that no matter if you set your Vcore manual, when you run torture tests like Prime or OCCT it raises the Vcore a little bit.

I would be interested to know which C-State can affect stability too, never though they could unless its low load stability.

Thread Starter 
c3 would drop vcore. C6/C7 is almost useless in terms of power savings, EIST will allow drop to 800mhz, C1E is like EIST.

also no gigabyte is adaptive, not manual override, but you can use adaptive like offset if you enable C3 state it will drop the VCore, but on newer CPUz versions(cpuz1.64.0 should be okay, but 1.65 will show VID not VCOre). Every CPU is different but it adds as much voltage as it needs when AVX is used, I mean what program you use in real life that uses AVX other than these stability test?

If your temp is going high then take a digital multimeter and read the vcore from the read points.VIN on auto will also might go up and increase temps.

Intel integrated two clock generators into the CPU, two different clock generator types, one is SBPLL and the other is LCPLL, that is just what they code them in the code, I am really not sure what the difference is other than, LCPLL is most steady, like less up and down margin of error, so like if you set 100.00 BCLK is allowed to sway up and down like 0.5% or less, LCPLL will allow less sway. SBPLL however will allow higher margin. So at default I think the board sets LCPLL and low filter, but I am not sure, it really doesn't matter much, I wouldn't mess with it, they know what they are doing with auto.

Filter level is how much the signal is filtered, if you are at high BCLK then you need a higher level of filtering b/c of the increase in jitter, but at lower BCLK the jitter is less and thus you don't need an overcompensating filter level. Same thing, BIOS guys auto rules work well.

With the latest FINAL BIOSes released in the past week or two, you guys shoudl be able to do pretty high BCLK even without the OC board, but only with 1.00x an 1.25x dividers, they will add in support for high BCLK and 1.67x divider very soon.

On the UD3H I can o 118.7 x 1.00x divider with BIOS F6 while BIOS F4 I couldn't. However this entails pretty long BCLK training, so you will see the board go from 15-95 over and over, maybe 7 -10 times and then it will finally boot. If you use high BCLK like this it will do this every time you change the BCLK, this is DMI/BCLK training. High BCLk like that tho is only useful for memory OC over 4ghz(4ghz memory I mean). Also that training procedure will get better over time, like on the OC board it only reboots once or twice and can do almost 200mhz on air now, that is how the UD3H and othe boards will be soon(all this with those PLL selections and levels on auto). A tip for BCLK OC: Lower your PCH IO from 1.5v to 1.2v wink.gif

HEAT HELP!!!

Okay using the Z87N Wifi ITX board. No expecting a huge overclock but figured I could get 4.2 to 4.3 GHz. I am using a Prodigy case with a Water 2.0 Extreme using dual Noctua 120 PWM fans in push for intake from the top. I have a 230mm fan for front intake a 140 rear exhaust. Idle temps according to Easytune are around 35C. I am able to get to 4.3 with just raising the multiplier and no other tweaking, system is stable but HOT, hitting around 80C.

This temp is achieved using AIDA64. Is this a normal temp or am I running high?
post #799 of 3244
If all you did was change multiplier and not the voltages, then your vcore will be pretty darn high if left on Auto on a 4.3 OC. Just find a stable Manual value for the vcore (for me personally I need 1.25V for 4.3, but I have a bad chip) and you should see temps go down

The wood is actually very smooth, like a desk, so it shouldnt be a problem? Mabey you know what else i could put under the mobo?


If you use motherboard spacers, your motherboard will not have any components lying on the wood.
