The GX2 is hard to ignore...

[TouGe]

Hi TouGe, your sig says bios mod for your 9800GX2. What exactly did you do? Last I heard there was no way to flash a bios to TWO/BOTH parts of the card, but only one. With the card containing two PCB's they both need a bios flash and NVflash as far as I know was unable to do this.

Already answered and very easy to do.

If you have found a way, or know something I do not, please do share! As well, did you lock in your desired clocks AND mod the fan speed by any chance? I loved this about my Ultra card. Have clocks exactly how I want them and fan speed at 100% at all times. I never need software installed anymore. My card just runs as I like right from the get go. This is what I would like to see happen with the GX2. As soon as they get dual display support while running SLI I will be grabbing this card and hope to tune the bios exactly to my liking.

As of NiBitor v4.0 the area where you would change fan speed is grayed out, so I don't see how we could change fan speeds right now.


Maybe with the next version of NiBitor we will be able to change this setting. Just use RivaTuner for now.

BTW, your new clocks in sig, is that your absolute max to sustain 100% stability and a clean image? What are your load temps in a worse case scenario with those clocks. Do you have a before and after temp for idle/load before you applied MX2?

As for my clocks, 702/1782/1080, these were the most stable for me. I could have set them at 720/1836/1062 but I would get infrequent glitches in 3DMark06 and errors in ATi Tool. When I am able to bump the voltages @ the BIOS level I'll probably revisit my current clocks but as they sit now I am able to score over 20,000 in 3Dmark06, so I am happy.
My Idle temps right now are 54/49 w/ fan @ 75%. When running ATi Tool I believe they were ~61/58. For some reason one card isdles hotter than the other. I noticed this when I first installed the card as well. I might try to re-apply MX-2 again next week to see if this changes anything.
My before temps were in the mid to upper 50's on both cards @ idle, so I gained 3-4 degrees w/ an additional 100MHz on the core clock.

I have the Thermaltake Toughpower 1000W Cable Management PSU.

Out of the wires that remain attached all the time, are 2 Black 8 pin connectors.
One Black 8 pin connector goes to my mobo wich is working fine.
My second black 8 pin connector is just hanging in space right now. (and can't be removed)

The extra wires that I can plug into the PSU have 6 and 8 pin connectors, but both are colored RED.

I know I will need to plug in 1 RED 6 pin plug in to power my GX2.

My question is, can I use my 2nd permanent Black 8 pin connector that is hanging in space to power my GX2, or do I need to plug a RED 8 pin connector in the PSU to power the GX2?

Could I still have a wrong 8 pin connector available to plug in, if my mobo already has one in it?

** UPDATE **
My PSU does have two 8 pin CPU connectors that are both Black!!
I need to continue to let that one hang in space...
Actually, I guess I can finally hide it now...
All this time I thought it was going to be needed for my future GPU...
It was made for running another mobo the entire time!

I will stick to the RED removable wires marked:

(1) 6 pin to 6 pin with 'To VGA Card Rail: +12V4' on one end, and 'To PSU Location V4' on the other.
(1) 8 pin to 8 pin with 'To VGA Card Rail: +12V4' on one end, and 'To PSU Location V4' on the other.

My V4 12 volt rail is rated at 36 amps max, with nothing currently plugged into it...
Word is on the net, that a GX2 requires a +12 volt rail rated at 28 amps minimum to work properly.
I should be golden.

Time to load this puppy down some! Common UPS Ground... Roll baby roll...
I wan't to feed this new monster card some juce!!
Then let er run like the wind!
