Drop of Gflops(even at stock speeds!) in 2500k under linx/ibt - Page 2

post #11 of 17
Thread Starter 
Actually I have tried to set short/long power limit to 255 and core current limit to 300. But this doesn't help the situation either.
Also, I haven't overclock the ram despite the high voltage. I have tried lowering the ram voltage to 1.53v and 1.485v but none of them helped the situation.

Also, I have run the memtest+86 for 2 times and there is no error(i.e. 2 passes)

Will try prime95 tonight.

So when I run this on my 2500k I've never gotten above 59. People say that it doesn't matter but that seems VERY low compared to others. I've went up to 4.6GHz and I still sit at about 57ish. Could this be because I have cheap-ish ram?

Yeah there's something wrong there.... I wonder what it could be...
The GFlops fluctuating way too much.
Have you tried it with lots of vcore? like 2 or 3 notches above what you have? (or just put it "Auto" to see what it gives you..since Auto voltage will give you enough to run it.)
Worth a try. Since for my testing, LinX uses one or two notch above vcore than normal Prime run vcore. But that was especially at higher clock (4.8Ghz or up), though.

You don't have IBT, LinX with AVX instruction sets.
You have to add it on.
You can google it to d/l.
Also Win7 SP1 is required for AVX.
Just to note, it'll give you 10c more than any other stress tests.
So if it reaches 80c in Prime, then running AVX will give you 90c or so.

Have you installed windows 7 service pack 1? You need sp1 to support the avx instruction. After that, your gflops will rise.

Yea, I tried 1.25v and 1.3v to run 3.4Ghz but the problem persists. I wonder how should I test whether MB or CPU makes the problem.

You should fill out your system specs so we know which RAM you are using, etc.
Also try asking the same question at xtremesystems ==> Official AsRock P67 Extreme4 thread.
Ask Ket. He knows the best about this board and probably give you some better trouble shooting you can try.
Only thing is you need $1 to join the site to post.
