Something is wrong with my cpu

[ShintaiDK]

With IBT

cpu at stock : ~46 gflops
cpu at 4.3 ghz : ~53 gflops

And the cpu is clocking up as high as it should.

Are you sure you use an AVX enabled version of IBT?

Try download and run this:
http://shintai.ambition.cz/linx.zip 64bit only. Its LinX as GUI for Linpack with Linpack 11.

Does normally the cpu hit a vcore of ~1.15 ~1.2 volt at 4.3 ghz ? Because it doesn't (something like 0.968 to 1.0).

Is that the standard IBT test?

Also what are you using to measure the voltage? It wouldn't surprise me if it was capable of a 400MHz increase at just less than 1v.

ShintaiDK : (I'm using IBT2.50) AHHH ! I think i got it ! I used the LinX you gave at the link and i completed one run in 3 m 28 s with 91.0807 gflops. Thanks a lot for you help guys !

Good to hear

Ok, now I'm having problems with the newer test, the 64 bit version runs once but says it can't go any further, That's after it's cooled back down. The 32 bit version won't even run!

Intel's version works fine as does everything else.

 

[ShintaiDK]

32bit version wont run in the LinX. Because the DLL is only for 64bit.
The package is simply for people that want the LinX GUI. But it does seem it behaves...awkward.

You can get the 32bit DLL here and the CMD version.

Now my bios is on offset voltage but when i overclock to 4.5 ghz my cpu, the vcore won't exceed 1.056 v(so the cpu in unstable). I knwo it need more power but it won't draw something like 1.2 v

When you change vcore to offset mode you need to change the offset value also. Did you change it?

 

[Ukaz]

Yeah LLC at extreme and a negative offset of 0.020

 

[Kenmitch]

Your gonna have to play with the offset value to get what you want under load.

Based on your 1.056v under load using a -0.020 offset.

If you want around 1.2v under load try upping the offset to +0.100v and see how it responds. You'll have to play around to get what you want under load.
