Wow

Cant believe you guys are getting your memory stable at X-X-4-X!

OCCT fails on my at anything i throw at it with tRP at 4 for some reason. It has to be 7. It appears i can turn off auto in memset and tighten All Precharge to Activate and All Precharge to Refresh delay manually though.

Dinos' is ofcouse 100% right about F3. It IS the best BIOS for dualcore setups. Memoryperformance is throught he roof compared to all the others.

At 4-4-7-7 460fsb 1:1 (920mhz) i get like 9450 - 8950 - 9250 53.2ms in Everest with the E6750 and Crucial Ballistix 1066 5-5-5-15 memory

As im writing this, OCCT has run for 6 hours at those settings.

F3 droops horribly though, but not under load. 1.53750 in BIOS = 1.5000 in OS idle, and 1.49 (and stays there) under load.

Also notice the 3.3V and 12V rails flucuate quite a bit more with F3 than F7 with LLC on.

Anyway. To anyone who has'nt done so yet. In memset, set tRFC to 20 or 22 and tREF to 16383T. Those should be stable for pretty much any setup, and give you quite a nice little boost in bandwith and latency.

Finally, i was pretty sure Performance Enhance = Turbo only meant TRD -4. If i set it to Normal in BIOS and set TRD down from 12 to 8 manually with memset i get poorer performance than with Turbo on. Not sure why this is,- maybe it actually does change something else, i dunno.

PS
Regarding TRD Phase adjust. Afaict, its used to fine tune the difference between two levels of TRD. Say you can run 8 but not 7, apparently you can set it to 8 and use Phase adjust to get "closer" to 7. Im not completely sure what the math is on it though, or if thats what it actually does, but it does seem to have an impact on performance (once you get a setting thats bootable). Any input on this setting would be appreciated.
