supply problems maybe in Asrock H67

[fbrbartoli]

Hi, My situation is this:
Asrock H67
i5 2500k
ddr3 2x2gb kingston
gtx 275

Continously driver crash with my xfx gtx 275. I change the vga with an evga gtx 275 but the problem remains. So I change the psu (lian li 650w) with a Nexus 650w. The Evga gpu doesn't start (the screen reamains black). So I reinstall the old gpu and the screen start but the problems of crash remains also with new psu. I check the memory with memtest. No errors.
For me is a problem of supply in motherboard. Is possible? I've checked all psu cable and they are connected properly. How can I fix it?
Thanks.

Hi, I solved it! The voltage ram was auto setting to 1.65v instead of 1.50v (1333 to be specific at 1.5v). the problem disappeared when I set it to 1.5v (the maximum voltage specification for ram with sandybridge).
Incredible ...
