2x BFG 7800GTX Official SLI Adventures

Okay they finally arrived
Talk about thermal paste on the ram chips!
I've been told by other BFG 7800GTX users this thermal paste on mem chips hampers mem ocs a bit as well.
Installed now with 77.72 WHQL drivers both have .25 bios and seems to have correct 460/1300 clocks
So far BFG 7800GTXs are doing fine although slightly disappointed with mem clocks so far mem can only go to 1380-1390mhz compared to some i've seen do 1450mhz on mem heh. Core does a nice 513mhz (+40mhz geometric) = ~553mhz.
2D speed is pretty low though clocked at 275mhz on the core.
easy cpu clock with BFG 7800GTXs
System
3700+ CABGE 0515 MPM San Diego water cooled
DFI NF4 SLI-D 414-3 beta bios
2x 512MB OCZ PC3200 Gold UTT BH-5
160GB Seagate 7200.7 NCQ SATA
Pioneer DVD Burner
510W PC PowerCooling SLI psu 34/38A 12v single rail
2x BFG 7800GTX with 77.72WHQL drivers
6.53 NF4 chipset drivers
WinXP Pro SP2
Rivatuner 15.6
@ stock 460(500)/1300
@ 487(526)/1386
Temperatures
With 92x38mm Sunon 120cfm fan on rheobus @1/2 speed blowing on back of video cards allows GPU idle temps to drop alot and get a bump in max mem clocks from 1386mhz to 1397mhz.
no fan
GPU idle = 45-46C at startup first time and 50-53C idling in windows for sometime.
GPU load = 76-86C
with 92x38mm Sunon 120cfm fan
GPU idle = 40-41C startup first time and 45-46C idling in windows for sometime
GPU load = 73-83C
here's with the 92x38mm sunon 120cfm fan @1/2 speed
In SLI mode, 3d2k05 and 3d2k05 are cpu limited. You really need a beefy cpu to really take advantage of these cards in SLI
Anyway couldn't resist landing myself officially in 3D2k3 Hall of Fame http://www.futuremark.com/community/halloffame/ (Had to take advantage of the 30+k bug heh)
3dmark2003 = 29,975
http://service.futuremark.com/compare?2k3=4116189
Wonder what it would take to break 13k in 3d2k05 ?
3dmark05 = 13,270
