I cant use my Patriot memory in Dual Channel with my MOBO P5N-E SLI.
My system is freezing when I use dual Channel
I checked the issue using memtest86, I tested both mem separated and together (without dual channel) and it passed in all tests, but when I tried to use in Dual Channel mode memtest86 shows too many errors.
Memory Model - Patriot PC2-6400 800MHz 4GB (2x 2GB) 5-5-5-12
In BIOS set the memory voltage to Mfg. specs, 2.0-2.1v. Also set the timings in BIOS. If that doesn't solve the problem increase the voltage to the NB. HTH. Your MB manual has an outline of your BIOS settings.
