Currently I'm trying to get 4x 2gb in my Asus P5k. Quite a hassle, cause they are not the same sticks.

Currently I got
- 3x Ballistic Firestix with 4-4-4-12 timings (PC6400) @ 2.0V
- 2x OCZ Platinum with 5-4-4-15 timings (PC6400) @ 2.1V

Currently I got the system running with 3x Ballistic FIrestix and 1x OCZ, but I'm wondering if that actually makes it slower because it's Dual Channel. For some reason I keep getting errors when I'm running the 2nd OCZ.

Btw, here are the Bios settings:
FSB at 425Mhz
Dram Volt at 2.1
Timings 5-4-4-15
NB Volt 1.55

It would probably be best to put the same sticks into the pair of dual channel slots. Don't rely on crashes as an indication of stability -- run the free version of memtest86 from HERE and insure that the particular configuration will run stable for a couple of test passes. Any errors are a problem.

Yup, different sticks often don't play well together.

I would keep it in the configuration that you have found stable. Running in dual (or quad) channel is really not much of an increase in performance, only something that you would notice in benchmarks not in actual use in most circumstances. It is certainly not worth buying a new matching set for an older rig.

Yeah, not worth buying new sticks, that's true. It's just out of hobby and to learn to overclock.

Anyway, 5 minutes after my first post it crashed, didn't handle the 8gb stable I guess. Would like to get the 8gb working though. So, you haven't really answered it yet, or I haven't understood it, but putting OCZ and Ballistic into a Dual Channel (mixed) does that severely slow it down? Or as long as they all run at the same speed/timing it's fine?
