I've just had 2x2GB Corsair memory delivered (from Scan). I can happily install and run Vista 64bit with 2GB but not with 4GB.
I've ran memtest seperately on each memory module.
One works perfectly fine and passed.
The other currently has 434000 errors and climbing.
I'm running on a Gigabyte EP45-UD3R motherboard, Intel Q6600 (stock speed) with the latest bios and default values (I've also tried with matching the 4-4-4-12 2.10V setting)
Any ideas if this is a misconfiguration problem (which I'm beginning to think unlikely) or have a just got a duff memory module.
Thanks
Chris
