Memory replacement question

[Sam DeathWalker]

Should go with 6 X 2G moduals.

You can get the slower/cheaper ones (but they should all be the same); ram is never the bottleneck in multiboxing.

PC-8500 is 1066 ram.

Just get the slower ram the PC-8500 or 1066 ram you don't need the 1333 ram, and if you mix you will just run at the slower ram anyways.

Best check if 4 rams are ok for your board, just a long shot. Seems 6 is better with i7 iirc.

If you have 4 I would order 3 more like what you have (same part number), and have a spare so you can swap out untill you find the bad one.
