Yeah, so yesterday I got my other 2x1GB sticks of OCZ Plat Rev2 6400 memory for a total of 4GB. I'm planning on going Vista x64 this weekend.

Anyway, I installed the additional 2GBs in my box and completely lose stability. I ended up having to drop my total OC from 3.4GHz to 3.2GHz on my E6600. I'm kinda pissed. I spent 3 hours trying EVERYTHING. RAM timings, voltages, MCH, etc. I'm not fully certain I'm totally 100% stable @ 3.2GHz - I only let Orthos run for an hour.

Damn. There's no way I'm forkin' the $$$ for 2x2GB DIMMs either, so I guess I'm stuck with this. I'm on 1503. A newer BIOS wouldn't allow anymore stability, would it?
