Nice work mate
Have you tried with lower vtt? I found on air and cascade that my chip didn't like high vtt. Even at max clocks on cascade I never went over 1.48v on Gigabyte EX58 Extreme. I am running dual channel though, perhaps the vtt requirement is less.
Might be worth a try in dual channel? Pi times will take a hit, but it might help you eek out those last few mhz for 3d.

By Boojyeah dual channel may need less CPU VTT (QPI/DRAM) volts than triple channel. With my setup the high mem clocks of GT require high CPU VTT volts too otherwise don't get stable memory clocks. But will try again as well as with looser 8-9-8-22 timings to confirm if it's memory or cpu heat/clocks holding it back
By DJGyup 0007 is older than 0001 bios
Took a side by side screenshot of my 12x mem multi DDR3-2184Mhz 7-8-7-20 1T 32M run versus my 10x mem multi higher cpu clocked DDR3-2118Mhz 7-8-7-20 1T 32M run to see what cputweaker reported for my subtimings. See if any subtiming settings are a factor.
DDR3-2184Mhz (12x mem) vs DDR3-2118Mhz (10x mem)
Going to play with subtimings and see
Update: Dropped cpu multiplier to 19x and using 10x memory multiplier, will try to reproduce similar looser subtimings as used in my DDR3-2184Mhz 7-8-7-20 1T run with 12x memory multiplier. I managed to get as far as Super Pi 32M stable @DDR3-2188Mhz 7-8-7-20 1T at 1.84v vdimm
Manually set following subtiming values in bios:
Super Pi 32M passed at:
DDR3-2158Mhz 7-8-7-20 1T at 1.72v
DDR3-2167Mhz 7-8-7-20 1T at 1.78v
DDR3-2177Mhz 7-8-7-20 1T at 1.80v
DDR3-2188Mhz 7-8-7-20 1T at 1.84v

Xeon W3540 HT Disabled
@4702Mhz - 4759Mhz at 1.568v
Was worth the effort in figuring out and applying 12x memory multiplier's subtimings for Corsair Dominator GT with 10x memory multiplier configuration. With manually set subtimings applied to 10x memory multiplier config, was able to get memory memtest86+ test #5 10x loop stable which was enough for me to pass Super Pi 32M @4702Mhz - 22x 214bclk with DDR3-2136Mhz 7-8-7-20 1T at 1.74v. That's a nice improvement over max 32M Pi @4660Mhz with DDR3-2118Mhz 7-8-7-20 1T at 1.84v
Super Pi 1M @4759Mhz
Super Pi 1M & 32M @4702Mhz

Swapped out single 8800GT for 2x HD4870x2 CrossfireX. I flashed back my HD4870x2 cards from Asus HD4870x2 TOP bios to their original ATI reference HD4870x2 bioses (plan to sell these cards soon). Full 6x2GB = 12GB DDR3 configuration with Windows 7 Ultimate 64bit and Catalyst 9.8 Hotfix drivers.
W3540 @4550Mhz at 1.472v
W3540 @4400Mhz at 1.384v
W3540 @4000Mhz at 1.184v

Pretty impressive numbers there considering you are on air, load temps must be getting up there. That's a great W3540 you have. Just going to stick with the 4890's now or you considering going green to replace the x2's?

Thanks Tim, I'm on water cooling not air so helps but stil high 80s C is not uncommon under load hehe. GPUs waiting to see what 5870 series from AMD/ATI bring but GTX 295 are tempting but still costly hehe
My new personal best 3dmark06 score ever = 31,812
3dmark06 = 31,812

Pushing it further with Corsair Dominator GT with 6-7-6-18 timings Pretty tricky getting higher due to fluctuating 3dmark06 cpu scores between runs heh
Finally broke 32k on water cooled cpu and stock air cooled HD4870x2 GPUs!
New personal best for Aquamark3 as well HD4870x2 CF @865/935 = 337,153 !
