I'll see what happens when I voltmod the thing... maybe those 4 pipes just need some extra juice =) Also, I think with a good voltmod I should be able to overclock mem to at least 900mhz and the GPU to 450 or more... I just need to get my backup card and cooling before that!

Flash Bios

I have the same card and also played a bit with pipes and vertex and had the same experience getting to 12/5 only. But I read on one of the formus that eVGA's 6800LE may be converted into 6800 Ultra by flashing bios. There was a version 1.4 of the Ultra bios pointed but newer ones may be available by now (have not checked yet).
Also a question here - has anybody tried to flash bios on the LE and with what results?

does eVGA's 6800LE share the same PCB as the 6800 Ultra? In particular the extra molex connector needed to power the beast.

By the way, this thread has been incredibly helpful as I just got my 6800 NU today. Unfortunately, remaining 4pipes are apparently damaged as i get artifacts running 3DMark05. However I did manage to enable the remaining vp and overclocked it to 383/813. So.. guess i'll try a bios voltmod next..

Guys, wats the stock core voltage for a 6800 NU? I'm using OmniExtremeEditfx to have a look at my original bios. It reports that my core voltage is 1.1V in 2d and 1.4V in 3D. Which one should i increase?

Well it took a log time, but I ordered my 6800 last wednesday and it should be here tomorrow, the 27th of June. :D

Well I got it today, and ive unlocked it fully. There is a tiny amount of corruption, and only on one map in half life 2 garrysmod, no other games so im not worried about it.
9655 in 3dmark03 with 16 pipes and 6 vertex shaders, stock speeds. Its so fast right now im not gonna worry about overclocking until I can afford an Nvidia Silencer 5.

I got the core to 400 MHz, but whenever I ran a 3d application something in my computer was buzzing :eek:
Its more than fast enough at stock, im playing far at ultra-high detail with 4 aa.

maybe the PSU? You're pulling a lot of juice with the vcore at 1.8v and then ocing the GPU ... do you have a multimeter to check the 12v rail under load?

Im at 2.4 GHz 1.7 vcore right now, its summer so its getting warm. I couldnt tell where it was coming from, ill see if I can get a multi-meter.

Does the 6800 really consume much more power at higher clockspeeds? Could be why the 6800 Ultra has 2 molex connections :confused:

Hi, I have problem about the chaintech 6800 LE. First off, after i install the card the system keep restarting itself after 30 min or so. So after use the RivarTuner to unlock the pipeline and found a few articfact i decide to close it, but then i reinstall the driver from the CD, but the next thing i know, the computer restart itself and a blue screen come up for a few second then the computer restart again. The computer won't even let me into the system. I want to ask how to fix this. THanks alot
