The next test was the RAM compatibility test. I was using a 64 MB Corsair PC100 w/parity module which uses Samsung SDRAM chips (KM48S8030BT = 2Mx8x4, 4k refresh, mapping 14/11) and a 64 MB Toshiba PC100 module (TC59S6408FTL-80H = 4Mx4x4, 4k refresh, mapping 12/9). I also used two 32 MB Samsung PC66 SDRAM modules (module : SEC KMM366S403BTN-G0, chips : SEC KM48S2020BT-G10 = 2Mx8x2). It’s my experience that modules with 2Mx8 chips are running better than with 4Mx4 architecture. Corsair has always used 2Mx8.
