memory dimm socket configuration problem, please help!

i have a overclocked p!!! on a soyo 6ba+100. soyo reccomends to use the dimm slots closet to the cpu first. well, i cant do this as the pep66 blocks the first 2 slots. my system has been running rock stable (havent shut it off for 2 monthes) with 1 256mb stick in the slot furthest from the cpu. so i decided to stick a second 256mb stick in the second from the furthest slot, the only one available. everything still works great. accept any 3d app that addresses agp memory. these apps (quake3,final reality,3dmark,etc.) when put into loop mode will run through about 25-30 loops then exit back to the desktop. no error message and system is not unstable after this. if i take out one stick of memory it works fine. it also has this problem when the system is not o/c'd. so all i can think of is to cut fins off the alpha, i wont do that.
memory timing and settings make no difference with this problem.
it looks like the bottom line is the mobo does not fully "jive" with the memory configured in these slots. which is no surprise, since it says not to configure the memory this way in the manual. also, the dimm tests ok on a dimm tester.
well, if any1 could think of a way i could get my extra stick of memory working in this system it would be greatly appreciated.

thank you,
sendatooli.

I'm sure you've tried Dimm "A" in Dimm slot 2 and 3, and Dimm "B" in Dimm slot 3 and 2, yadda. I tried 448 Mb of Sdram recently. I could see no difference between it and 256 Mb under Win98SE. If you're running Win9x, I doubt that you can tell the difference. Certain progs still ate up all my Ram, so I think more than 256 Mb may simply be conspicuous consumption. If you're running Solaris 8 for x86 architecture or Win2K, the extra Sdram will definitely be used.

Don't feel too bad, you now have enough Sdram to create an "empire" of two boxes!
