chubien Posted November 18, 2004 Share Posted November 18, 2004 Hello, I bought a matched pair of TWINX Platinum Series one year ago and have been using them reliably at 190 fsb (1:1) with a barton 2500 cpu (prime95 stable 10 hours). I recently built another similar computer (barton 2500 also) running on generic ram (3-4-4-8) at 217 fsb (1:1). Seing that the new system would overclock much nicer, I decided to use my corsair XMS3202 v1.2 CMX3200C2PT in the better computer to acheive maximum performance. To my surprise the new computer would only acheive 190 fsb (1:1) with the default timings (2.7v, 2.5-3-3-6) on the better corsair RAM. Obviously the 190 fsb limit on the old system, and now on the new system is memory related. I had always assumed that I had reached CPU limit at 190 fsb, I did not want to up the voltage as I was on stock cooling so left it at 190 fsb. I proceeded to running on just one of the memory sticks, using any of the memory slots, using synched (1:1) or SPD (200 Mhz). One of the memory sticks will run just fine, at 1:1 at 200 Mhz, 2.7v, 2.5-3-3-6 and beyond (will actually acheive 208 fsb prime 95 stable). The other memory stick will boot windows at the same settings, but very unstable, will fail prime95 within seconds. And his regardless which memory slot, voltage, SPD or 1:1. Funny enought though it will run prime95 longer before posting errors with tighter timings (2-3-3-6). But it would still only do a best of 3-5 minutes before dying. I ran memtest overnight and it found no errors ... what gives !?
