Problem with ECS Mobo & 4GB Memory

[RRRuss]

I currently have an ECS 965A in my system, covering an Asus P5B-D, whilst it is being RMA'd.

I was happily using 4GB of Giel memory in my Asus, but my ECS is having none of it.

It runs perfectly fine on 2GB, but as soon as I increase this to 3 or 4GB, I encounter repeated BSOD's.

Any ideas please? Hopefully I should only have this a few more weeks, but it's driving me mad...

Thanks.

Back off on the timings / up the RAM and northbridge voltages and updating BIOS are your main options
