XMS2 doesnt work with 4 sticks, settings help pls

Hi guys,
I just installed a new MB and transferring my existing 4 sticks of XMS2 2GB sticks. Vista 64 SP2 is stable with 2 or 3 sticks but the 4th stick just doesnt want to cooperate. Vista crashes, no display on post, all sorts of no fun things happen. Any suggestions for timings or voltage to get this working?

CMS2x2048-6400C5
5-5-5-18 2T
1.9V ver 3.2

Ive tried to fool around a bit on timing but I do not know enough about it to really get anywhere. MB is a XFX MB-N780-ISH9. BTW no overclocking on anything, just trying to get it stable now.

Thanks!

This has been posted many times about running 4 modules and I would test one module in all four slots to make sure one of the slots is not failing.

With 4 modules I would suggest setting the memory frequency at DDR667 and set the memory Voltage to 2.1 Volts and set the NB/MCH/SPP Voltage to +.2 Volts as well and test the system with www.memtest.org. In addition, with some MB's (Mostly ASUS) you have to disable legacy USB in the bios when running any memory test.

actually one of the sticks failed memtest and i am sending it back for RMA. That happens to be the 4th stick I was trying.

You will have to get them replaced as a set if you purchased them as a set.

yes I am aware of that. I have the other stick tho it may of gotten shuffled with the other 3 sticks. I will be sending back 2 sticks.

You can look at the modules lot code to match them up.
