Help stabilize DDR600!

A little background in the AMD CPUs section: http://www.ocforums.com/showthread.php?t=405703

Here's where I'm at:
290x9, 1.46v, 1:1 primed for 15 hours before I stopped it to tweak some more. I have reached DDR600 by loosening some timings, it will do a 1M SuperPi, bt not 32M. I lowered CPU multi to 8 so I can tweak just the memory.

HT/FSB: 300
HT multi: 2.5x
CPU multi: 8x (2400mhz)
CPU volt: (1.325 + 123%) 1.46 (read from MBM5 / ITE SmartGuardian)
Vdd: 2.9v
LDT Volt: 1.5
Chipset: 1.8

DRAM Timings:
1T
Tcl: 2.5
Trcd: 4
Tras: 6
Trp: 3
Trc: 9
Trfc: 14
Trrd: 2
Twr: 2
Twrt: 2
Trwt: 2
Tref: 3072
Twcl: 1

Banke int: Enable
Skew control: 255 +
Drive Strength: 7
Data strength: 1
Max. Async: 8ns
Read Preamble: 5ns
Idle Cycle: 256
Dyn. Counter: Enable
R/W BYpass: 16x
Bypass Max: 7x
32Bit Gran.: Disable

Setting data strength from 2 to 1 helped me go from 290 to 300.
I tried setting Trp from 3 to 4 and Tras from 6 to 10, but gained no stability.

What else should I try? Anything I could do to get Trcd 3 back? Once I get the memory stable, I'll see what my Venice has left in it.

Try these settings that I optimized:

Tcl: 2.5
Trcd: 4
Tras: 7
Trp: 3
Trc: 11
Trfc: 20
Trrd: 3
Twr: 3
Twrt: 2
Trwt: 3
Tref: 3120
Twcl: 1

Banke int: Enable
Skew control: 255 +
Drive Strength: 7
Data strength: 3
Max. Async: 8ns
Read Preamble: 5ns
Idle Cycle: 256
Dyn. Counter: Enable
R/W BYpass: 16x
Bypass Max: 7x
32Bit Gran.: Disable

Be sure to let us know if it works and post your final stable results in the SuperNades DRAM Database.

I just recently stabilized my RAM at 310mhz with similar settings. The settings that made the difference for me was setting R/W Bypass to 8x and Bypass Max to 4x. Also try Decrease Skew by 128. You might want to try running it at 2.7V. It's been my experience, and I've also heard it elsewhere, that anything above 2.7V decreases stability. I've run mine up to 3.1V and 2.7V still gives the best results. Far from a definite thing, but something to consider nonetheless.
