I just recently exchanged the 1GB Xtreem DDR600 TCCD memory for
2GB Xtreem DDR500 UCCC memory. But when I atempted to overclock
the memory the max was 257Mhz (on a 166 divider). When set to 263Mhz
(HTT322) Super Pi 1M errorrs immediately
I was under the impression that Xtreem memory is premium stuff and yields
quite nice overclocks (I was hoping to achieve round 275Mhz), since one of
my friends managed to OC his generic PQI ram with UCCC chips to ~270Mhz.
Am I using too tight timings...voltage is 2.6v (more voltage doesn't help)?
Also when testing with Memtest (Bios/DOS version) at 263Mhz 1 pass of test
#5 gives 4 errors, but when swithching the sticks it produces like 500 errors??
Maybe a different board would do the trick..I have another Ultra-D board (rev. AD0),
the one in use is AA0 (made in China) with the latest official BIOS.
Update: Well, I just got news that Prime blend test failed after 2hours. The memory
was running at 254.5Mhz (HTT311/divider 166) and relaxed timings (I loaded the
optimized defaults and set 3-4-3-8 manually, all other settings are on auto).
Can cpu voltage set to low affect this...the voltage is 1.4125v (1.25vx113%)?
