OCZ VX PC4000 issues

Recommended Posts

I'm a bit of a n00b, so go easy on me.

My VX memory won't run @ 2-2-2-8 timings @ 3.27v. It fails memtest every loop. I relaxed the timings to 3-3-3-8 and it passes memtest fine. This memory is rated for 2-2-2-8 @ ddr500 w/3.2v. So, what could my problem be?

 

Bank interleave - disabled

LTD Voltage - 1.4

Chipset - 1.8

Change over to 5V and then run at 3.3V. I'm currently running at 11 X 250 2-2-2-6 with VX RAM

Kronos, what do you have your VID set at. I have the exact same setup as yours but I can't get past 240 stable and at 250 windows wont boot. I know its not the memory because it passes memtest+ at 250.

The memory will need 3.3v-3.5v to do rated speeds.

 

You will also need to have your timings set up properly. If you need help you can PM me or email me. We can also do it right here. :)

These look like excellent settings to try.

 

If you still get memtest errors, I suggest testing each stick in slot 2 by itself. Report your findings here or PM me again.

 

Thanks
