VS2GB1333D3 + ASRock 880G extreme 3

[limp_limp]

I bought my new system with Athlon X2 220, MB 880G extreme 3 and with 2 ram Corsair VS2GB1333D3.

 

Although the 2 rams are not kit set, I still put them in dual channel mode.

I set most AUTO in BIOS in RAM setting.

 

The system is fine, and I unlock the CPU to Phenom II 920.

After I installed Win7 Professional. The first run is smooth, then I turned it off and went to sleep.

The next morning, the nightmare started, when I turn it on, login to WIN7, after 30 sec to 1 min, BSOD saying memory management and it reboots.

It keeps BSOD -> reboot. I tried a several method, like unplug the ram, lock the CPU back to 220, manually set the ram voltage to 1.6. Then somehow it will work fine. But after I closed for hours, the problem occur again, and I have to try those ways again.

 

And I use single ram only, the system was totally fine. Then I tried single channel with 2 rams, same problem happens.

 

I take both ram and MB to retailer for checking, they are all fine.

 

Is that a compatibility problem or something?

 

Thank you

Mixing of RAM is never guaranteed. It could also be a mobo/BIOS issue. Have you tired updating the BIOS? You could also disable the core that you unlocked and test again.

Yes, I've tried the disble to core and re-test, still failed.

The BIOS is the latest 1.70 version already.

So I can't use 2 ram with the same model, no matter dual or single channel?

Two DIMMs may or may not ever work as they aren't one tested, matched kit. There is no guarantee when mixing RAM.

 

There are a few things you can try. Set the timings to 11-11-11-30, 2T @ 1.65 V. You can also try setting the CPU-NB to 1.26 V.
