I don't understand this, I recently purchased a 512 meg ram module of corsair 4400ram to add my current 2x256megs of corsair 3200 ram. Now here's the deal. I was able to get 100% stable in memtest with fsb 203mhz at timings of 11,3,2,2.0 with my two 256 sticks of corsair 3200 ram, but this new stick of corsair 4000 512meg ram can't handle timings that tight at the particular fsb. Any explanation for that? The 4000 ram module is
CMX512-4000PT XMS4000 512MB 3-4-4-8 184 DIMM Platinum
Since the module listed above are tested to run at 250mhz fsb, why wouldn't I be able to bring the latency way down at 203mhz fsb,
I can't simply increase fsb as my other 2 sticks of corsair 3200 256 ram sticks will fail in memtest and also my cpu doesn't like certain multipliers meaning like 10 meaning if I went to 220mhz fsb I would have to set my multiplier to 9.5 yieliding me 2090Mhz whereas my cpu can handle normally 2.3Ghz max stable. My cpu likes clock multplier 11 but 11x220=2.420Ghz, which will my computer will post and pass memtest prime95 will crash in seconds. Right now my computer is running at 205mhz fsb X 11 = 2.264Mhz, and ram timings are 3,3,3,11. Like I said when I had just the two sticks of 3200 I was able to go at 203mhz fsb with timings of 2,2,3,11. Any ideas fellas? What do you advise?
Also another question, I've really been gauging memory performance by the transfer rate of ram reported in memtest. Memory timings really change this number to the point where I could easily have memory running at 220mhz with laxer timings performing worse than tighter timings at 203mhz. Is this a valid way to look at it?
