Hey, I had one stick of Infineon DDR400 Ram. I recently bought another stick, same brand, same speed, etc to run dual channel with. I've had dual channel working before using my one stick of DD400 and a stick of DDR333 and it worked fine. Now when I try to run dual channel, it works fine at stock speeds but when I try any oc at all, I get a series of long slow beeps during POST. I used to be able to oc up to about 2.3Ghz with my old slower ram, but now with my new ram I can't get any oc at all.
Infineon DDR400Mhz (256x2)
Athlon 2800+ Barton (unlocked)
Any idea why I can't get any OC out of this at all. And why upgrading ram has unabled me to do anyhting past stock speeds?
