As far as the RAM goes you might raise the tRFC a couple ticks from the auto setting to help stabilize the RAM, but may well be the GPU Driver (especially since things seem to crop up when gaming/video), might want to make sure you have the latest driver or latest beta, and possiblty even drop back a version to see if that helps.

At first I thought it was driver issues so I downloaded the latest ATI drivers (the problem persists) but the thing is that when the computer locks up there is no Bluescreen and Windows other than knowing that the computer wasn't shutdown properly doesn't have any recollection of any driver error and to my knowledge that points to hardware issues.

So then I moved to the PSU because I noticed that under load the +12v was dropping to 11v or lower when measured with a DMM so I sent it back to PC Power and they replaced it and now the +12 is at a steady 11.9v and the lock ups continue.

Now I'm at the RAM so I'll try your suggestion

I increased the tRFC to 90 and tried to play a session of Bacompany 2 and it locked up after 15mins of play. Again no bluescreen and windows thinks the PC was just shutdown improperly. Also I forgot to mention on the OP that temps are all normal.

Now after setting the tRFC to 90 the system is locking up randomly even if I set it back to auto. I even tried 100 and still no luck.

I really need help with this, now the PC is locking up and not only in games but also while just browsing or when idle.

Any Gskill tech on able to help me resolve this pls?

[xample22]

Can someone at least tell me some settings that should be stable for my PC?

[GSKILL TECH]

Sorry for the delay. Please PM me directly if I do not respond within a couple days.

Set QPI/DRAM Core Voltage: 1.40V

Let me know how that goes.

Thank you
