IMC Problem?

post #1 of 13
Thread Starter 
To the point

Ok here is my spec :

- AMD Athlon II x2 260
- j&w Minix 890GX
- COrrsair SODIM DDR3 CMSO8GX3M2A1333C9 (2x4GB)
- Psu Xigmatek NRP PC 402
- Nvidia GT 220

I've problem running dual channel DDR3 on my AMD. First time it's completely fine, until someday the monitor goes blank, always bsod, hang in bios and now just can running one stick of memory.

I have test the two memories using memtest86 with no errors.

I've already rma the mobo, doesnt help. Trying another memory brand(used V-Gen before) with no luck.

Does my cpu has very weak IMC or the mobo has bad slot? I have stuck with one memory right now.

Any suggestion would be appreciated.

unknown board to me but trying bumping the CPU-NB voltage up a notch or 2....if you can.
This will increase stability.

Well, my mobo is mini ITX form factor. I want to build HTPC at the first. But stuck with memory problem. I've tried to bump CPU-NB voltage to 1.25 from the default 1.175. It worked for sometime, but back to the unstable state again. Does the IMC fail ? Some forum stated that the IMC could fail and just allow me to run single channel mode.

Is it really IMC problem so that i have to rma it. It may still has the problem coz the weak athlon II IMC. Should i replace the cpu with Phenom II?

Sorry for the bad english, and thanks for the reply anyway.

up th ram voltage to around 1.6-1.65

I don't overclock my rig coz i want it keep cool and save power consumption.

I've tried many ways to get it stable. Including increase the memory voltage to 1.65. Upping CPU-NB voltage and Memory voltage do increase the stability. But it was just temporary in my case. It only hold up to couple days before it back to unstable state again. And if this happened, the bios failed to post with blank screen, sometimes hang in in bios and no way to get a ride into windows.

It seems play well if i only placed one memory slot.

Any another opinion ? What should i do next.

Sempron and athlon II x2 imc works @1066, that can be the issue here. As someone already told you, try increasing cpunb voltage in your bios setup. You can also try lowering the ram to 1066 and see what happens.

I didn't touch the cpu vcore coz i thought that it was enough to feed my cpu.
It was 1.4v vcore. Upping the CPU-NB voltage up to 1.25, couldnt push further due to random restart after this. I also downclocking the memory to 533 with no luck.

This is the first time having this issue. Anyone has simmilar problem running 8GB DDR3 on Athlon II X2.

Is it possible my imc has failed according to this thread :



Thanls

The worst thing increased RAM speed may bring is temporary instability that can be solved with a CMOS reset and trying again with different timings and/or voltage. Many Athlon II/Phenom II IMCs handle the increased RAM speed with zero issue. Don't trust this article.

@OP: RAM slot on mobo could just about be dead.. test both slots? Try CPU-NB voltage too. DRAM voltage should not be increased past 1.5V on 1333 CL9 memory unless you experience DRAM voltage droop.

Hey guys, i've tried the second slot. And it looks like the problem was there. The issue raised while i was plug the stick on the second slots. But i'm still not sure if the problem is really the second slot. Coz this is my second board. I've already rma it but the issue persist.

Is it possible another part of IMC failed or it is really the slot has defect? I dont really know how the IMC works.

Thanks u so much.....
