Guys,

Spent the morning OC'ing Memory.
Here's a link to a screenshot of my maximum stable memory OC.

Sorry for the grainy picture, it's a bitmap file and I needed to compress it to get it on imageshack. Incase you can't read it,
This was Corsair Value Select PC3200 CL2.5 RAM
I managed DDR450 which I think is pretty D42n3d good, considering I only ran it @ 2.6 V VDimm and 2.5-3-3-8 1T /smile.gif' border='0' style='vertical-align:middle' alt='smile.gif' /> (Didn't want to crank the voltage as these sticks are going into my wife's machine on Monday when my OC-Z PC3200 Platinum Enhanced Latency Rev 2 memory comes from the egg).

Here are comparison specs:
Total Bandwidth (1024MB) from PC Wizard 05 Stock: 3073 MB/Sec OC:3412
Integer Bandwidth (512MB) SisSandra 05 Stock: 3041 MB/Sec OC:3418
Float Bandwidth (512 MB) SisSandra 05 Stock: 3042 MB/Sec OC:3416
Latency DDR410: 49.59 ns (112cycles) down to 45.13 ns (102cycles)@DDR450
I ran super pi for stability (89 seconds @ stock and DDR450) besides the bandwidth benchmarking, then ran OCCT stability at DDR450.

Other notes: Max Mem Speed was DDR452 (226MHz) but CPU-Z started behaving funny. I then changed timings to 3-4-4-12 2T, but couldn't get it to boot into windows2000. Figured I could go looser on the timings, but once the CMD rate change to 2T with no improvement, I decided the higher speed wouldn't be worth the bandwidth hit. Clearly a boost to 2.7 might have got me to DDR460 or slightly higher, but being as this was binned as Value RAM, I decided it was pretty good at DDR450 (will wait for the OCZ /wink.gif' border='0' style='vertical-align:middle' alt='wink.gif' /> ).

Will OC the CPU tomorrow morning for max CPU and HTT OC, then work the numbers for max OC for this set up and bench it. Hope to post results by Sunday night
By the way, settings were: HTT 225, Multiplier 10X (CPU speed 2.25GHz underclocked) HTT @ 3X.
And to do a thorough set of benches(15 runs), this took approximately 3.5 hours (I started at 0445 hours /blink.gif' border='0' style='vertical-align:middle' alt='blink.gif' /> )
Let me know what you think.
Cheers,
MM
