ya right there

This didn't make any difference as far as I can tell.

Didn't help.

See below.

Thanks.

Yes. 174, 175, 180, 190 and others that I've forgotten.

I flashed to the 1/23 pre-beta bios. I then kinda through in the towel. I've swapped memory. I'm now using my dual channel Corsair DDR3-2133 so I'm going to start over with this memory.

I was doing something close to this but it's nice to be reminded.

Here's the DRAM timing listed in the BIOS. Which of the subtimings to you set?

75 i get when vdimm and cpu vtt ain't enough for clocks set, 88 yeah means switch of psu and then hold home key while hitting power to revert to default bclk

loosen everything up and work back to tighter timings as you test

so

REF to ACT Delay (tRFC): 88 and higher

Write to PRE Delay (tWR): AUTO | Yes
Rank Write to Read (tWTR): try values between 20 to 28
ACT to ACT Delay (tRRD): 6 or higher
Row Cycle Time (tRC): AUTO | 31
Read CAS# Precharge (tRTP): 6 or higher
Four ACT WIN Time (tFAW): 31

More results from me

Max 6x1GB 8-8-8-24 1T Clocks
Changing to 10x memory multiplier, tried to find max 6x1GB 8-8-8-24 1T clocks and ended up with DDR3-2000Mhz 8-8-8-24 1T at 2.04v bios (2.045v real) only for tried 1M Super Pi as 32M Pi test failed. I dropped bclk and mem clocks to DDR3-1960Mhz 8-8-8-24 1T at same vdimm but Super Pi 32M failed at 22nd iteration. Similar trend occured at DDR3-1940mhz as well.

I recall it's probably the Cellshock PC3-14400 Micron D9GTR holding the 6x1GB modules back as it needed more vdimm for do such clocks even on P35/X48 DDR3 boards closer to 2.1+ volts for around DDR3-1920 8-8-8-x. Decided to stop there as unnecessary stress to i7 IMC ain't needed when I shall have some nice DDR3-2000 CAS7 rated triple channel memory due my way this coming week
