Dual channel = Less stable than Single??

[Siphilon]

Hi I've got a quick dual channel question. I've had this 2.0A B0 stepping processor @ 2.7 (seems about standard for that stepping) with some GEIL PC-3500 Ultra Platinum memory.

I just picked up (2) Kingston HX PC-3500 chips with hopes to get a little bit more performance out of this setup. But when using them I can't get the processor even close to 2.7....only about 2.4 now.

Could anyone enlighten me as to what I might do to recoup that extra speed? Granted, the system still performs a lot better with the dual channel memory, I'd kind of like to know whats going on with the processor.

Here's the spec rundown:

2A GHZ B0 stepping
Albatron 865PE Pro II
TTGI 550 Watt PSU
GEIL UP PC-3500 & or Kingston HX PC-3500


I've tried giving the cpu & or the memory a little more voltage but that has not helped. Is it maybe because the CPU is working harder with the dual channel setup?

Thanks in advance..

im not a memory expert by any means. however, it is a given that in dual channel more components have to interact -memory controller, interleaving etc. so i would expect a small hit in performance. but your drop off is really significant. maybe a bad or underperforming stick? try testing each one seperately in comparison with the geil...
