So I just upgraded to 2 Gigs (finally) of CMX1024-3200C2PT (a TwinX kit of 2 x 1024) only to find that it will not overclock very well at ALL. By this, I mean that setting the FSB to 225Mhz (DDR450) will cause my memory to fail memtest on the first of second pass on Test #5. My old RAM (a TwinX kit of the same stuff of 2 x 512), ran at 250Mhz stable. This is what I've tried so far:
1) I reverted my BIOS back from the beta version (1302 or something like that) to 1009 (a stable version). Still had errors on Test #5 in first pass or two.
2) Changed timings from the rated 2.5-3-3-6 and ran at 225Mhz. Same problem.
3) Changed timings to 3-3-3-8 and ran at 225Mhz. Same problem.
4) Kept timings at 3-3-3-8, upped the DDR Voltage to 2.80 V. Has currently run through test #5 6 times with no errors.
However, I am really not happy that I have to run my memory at 3-3-3-8 and only achieve a 25Mhz overclock. This is really hindering my performance since I have an Opty 165 that I have gotten up to 2.7Ghz. Any suggestions on what I should do? I am thinking about dropping the timings back down to its rated timings, keeping the voltage at 2.80V, and setting it to 2T Timing, but I have heard that that will slow things down even more than just increasing the timings.
Any advice? Do 1 gig sticks just not overclock as well in general or what?
Thanks in advance!
