I have a P4 machine that is about 2 years old. ABIT IS7 Motherboard and from it's creation has run 2x512 OCZ PC3500 RAM (P4 OCd to 433) in Dual Channel.
Recently I purchased another match pair of PC3500 OCZ RAM to add on to my system. I added the new pair to slots 2 and 4. System booted, got into windows and promptly started tossing errors before BSOD.
I remove the new RAM, boot and all is well. So I start testing. I can boot with the new RAM by itself completely fine (tested all four slots with both new sticks). I can run pretty much anything on my machine for long periods with absolutely no errors. I can even run both sticks at the same time as long as they don't activate dual channel. Example installing them in slots 1 and 2. I can also run my previous RAM in dual channel in slots 2 and 4 with no issues.
The second Dual Channel is activated for these 2 sticks, regardless of position (1 and 3 or 2 and 4) all hell breaks loose on my system. Is this something specifically with the RAM? I've run my current match pair for years without so much as a glitch but the new RAM seems to run fine when not in dual channel. Any ideas out there?
My Motherboard is on the latest BIOS revision and to be safe I let the BIOS determine the timings instead of setting them myself.
