Low temps in LinX

post #1 of 12
Thread Starter 
I recently found out that one of my memory modules were faulty. It gave an error in HCI Memtest. The reason I found out that something was wrong in the first place was because of LinX, because it would give me an error on the first run. So after I removed my faulty memory module I naturally tested with LinX again to see if it was stable. The problem was only that my gflops had dropped from around 80 to about 40 and my temps were 20°C lower. And all I did was that I removed one of the three memory modules from my system.

What is the reason for this drop in temps and gflops?

what do you mean it dropped from 80 to 40 gflops? Before you remove the faulty ram, it was 80 gflops in linx? Then after removing it, it went down 40? Or the first result in linx test was 80 then the following minute it was 40? Because if its the latter, it's probably because of the cpu throttling down..

Did you try to put the dimm back in and check if the temps and GFLOPS went back up again?

i don't think ram has anything tt do with CPU Gflops. Maybe increase CPU voltage one notch.
post #7 of 12
Doesn't make sense, even if LinX is using less free memory which makes the test less stressful, the GFlops performance rating should still be the same.

Sounds like an unstable OC. More tinkering around is needed with voltages and frequencies.

Just remember that a few runs on LinX, even on MAX memory does not mean your overclock is stable.

I have had LinX error out on the 47th run using MAX memory before. Obviously at this point you know its fairly stable so a bit of minor tweaking usually sorts it out.

You should only use LinX and other burn test programs as initial tests. The real test is how your PC holds out under general use and during long gaming sessions.

I've tested this overclock with prime and it passed 22 hours with 100% memory usage. (I think my settings in prime were 8k to 1024k with 100% memory) But I will try again and see if I can make linx give me the right results.

I've tried upping the vcore and the gflops gets a little better, but nowhere near what I got with three memory modules. I managed about 72 when I set the vcore to 1.45 in the bios, but that's a lot more voltage than the 1.41 it passed 22 hours of prime with.

I also downloaded the intel linpack library but it didn't make that much of a difference on the result.

And btw, when I ran linx with 1.41 vcore earlier today I think it managed about 56 gflops. I know I said 40 in my original post, but that may have been too low.

Your CPU may need more voltage if the gflops are that low (40's), I get around 55 gflops with my CPU (980x equivalent) which is right around where your getting.
