Cannot Set Clocks - 2x BFG 7900 GT in SLI

[Master}{]

I have 2 "BFG 7900 GS" cards in SLI and atitool fails to set clocks

the cards specs are as follows:
G71 90nm chips
256mb gddr3 256 bit
Watercooled and ramsinked
both cards are running true 16x pci-e speed on a 590 series motherboard
163.75 NForce Drivers
Samsung SyncMaster 220WM 22in LCD running max Resolution @ 1680x1050x60

System Specs.
ThermalTake Armor Extreme Edition Super Tower
AMD Phenom x4 9600 Black Edition clocked at 2500mhz - no errata patch - Watercooled
Asus M2N32 SLI Deluxe Motherboard
--NVidia NForce 590 Chipset with full 32X SLI
Ultra V 550W Power Supply
4 GB Patriot DDR2 6400(800mhz) 4-4-4-12 lats (2 x 2gb)
4 GB Giga-byte I-RAM Solid State SATA 150 Disk - bootdrive
2 x 160GB Seagate Baracuda SATA2 in RAID 0
2 x BFG Tech GeForce 7900 GS-OC 256MB 256-bit GDDR3 (565/1600) Watercooled
--FW: 163.75
--BIOS: 5.71.22.41.65
--DevID: 10DE - 0292
SONY DVD-RW 18x on UDMA/IDE
Windows XP-32bit SP2
Had XP 64 bit on secondary boot drive but the install had decided to BSOD on boot, have yet to do repair install

ATITOOL - 0.27 - the one in the beta topic as of this post date.

All else seems to display correctly, pipelines, rops, current clocks, etc, but cant change jack shiete

you cant set clocks like this for an SLI configuration... you have to do it the pain in the @ss way: flash each card's BIOS individually... (At least the last time i checked) but it is worth it. Have you tried Ntune or whatever? rivatuner 2.07? there are better proggies for OCing Nvidia cards than ATI tool for SLI set ups.

Nice setup BTW...

W1zzard would know for sure, tho. I may be wrong, just the last i heard, you had to flash each one.

try untinstalling and reinstalling the nvidia drivers.

welcome to TPU.

Rivatuner seems to work fine to set the clock in or out of SLI, as well as ntune,

i decided to try atitool for a change since i hadnt used it in about 3 or so years.
the drivers were just installed 3 weeks ago when i built this rig. i used the elder
163.75 drivers because for one reason or another they seem to provide a slight
advantage to the latest or even the beta drivers as far as performance on my cards.

I just upgraded the MB, CPU, and RAM and brought the SSD, hard drives, and videocards
from my previous dual core setup.

One bad thing about this system is that ALL overclocking
tools flat out wont touch this phenom quad core....

NTune doesnt see that i have a cpu, and the multiplier says 4x in its settings.
Athlon64 tweaker crashes on launch.
Central Brain ID overclocker crashes on launch.
Clockgen says my cpu speed is 500mhz with a fsb of like 12???
ASUS AI Booster works except the multiplier settings.

my only salvation is overclocking in the bios....but screwups mean clearing cmos versus just rebooting. this cpu makes it to 2640 with a FSB of 240, multiplier set to 11 and, and the memory ocs to 960mhz if i drop timings from 4-4-4-12 to 5-5-5-12 @ 2.2V

Any faster i can game and such but any attempt at 3dmark hangs half way through or so....
Temps arent high, but these damn phenoms have 2 cpu voltages, and my board is old enough to not know about the second voltage for the cpus onchip htbus. so far not in any new bios imgs either......

Any help getting ATITOOL to support this is offered....

BTW yes phanbuey, i use nibitor to set my clock settings in the card bios once i verify there stability with some call of duty 4....
