The Dell 6800GTO is essentially a 6800Ultra that ultimately failed the final run of QA tests apparently, and you will notice several layers of stickers confirming this on the card. Remnants of it's Ultra origins include the double width bracket and PCB. They bundle it with the stock GT cooler however, with very conservative fan speed values.
It is however a 12 Pipe / 5 Vertex Shader unit, which runs at 350/900 (GDDR3 - 2.0ns)
Many people have sucessfully unlocked these puppies to full 16x1x6 making them at least as fast as GT's if not Ultra's.
My personal 6800GTO is running at an Ultra crushing 430/1230 (16x1x6) and enjoys the tighter memory timings of a GT board. Not a bad deal for $330.00

Are you using one of your cooling heatsink/fan combos to achieve that? I am trying to decide what to slap on my GTO. Currently unlocked and overclocked to 402/1101 on stock cooling (no problems/artifacts that I can see). Typically idles at 57C with loads in the 80s (maxes in the low 90s with HL2, etc.), in my Dimension 8400 case (ie., not that great for cooling!). I have been considering the NV5 rev 2 and the Zalman VF-700 Cu, but will also consider your offerings. I had been leaning to the NV5 just because it vents some of the hot air out of the case. Since the 8400 does not have that great of air flow, I am concerned about dumping the air into the case (like with the Zalman and your alternatives(?)). What kind of temps do you have on your GTO? Have your case temps risen with the new cooling for the GTO?
THanks.

The Dell 6800GTO is NV40 card however, not a NV41 fortunately.
My test mule is a Dell 8400 as well, as it's a stable platform that I can get consistant temperatures with which is important when comparing designs. It also sets a very low baseline for cooling which nearly all of my clients can easily exceed, so none of my temperature ratings are ever inflated.
With the stock cooling, I was not able to unlock any of the pipes under any circumstances. With the eVGA copper GT heatsink, Arctic Silver 5 on the GPU and Arctic Ceramique on the RAM I was able to unlock the pipes, though anything past 400 on the GPU would cause artifacts.
With the IceStorm NV6800C5 I can hit 430 core/1230 memory with stock voltage. Idle temperatures in the 8400 are 36C and load temperatures are between 55-60C depending on the day.
(With stock cooling idle was 70C and load was 95C)
For the Dell the NV6800C3 might be your best bet, though if you want balls out performance the C5 is the way to go, though you will lose 2 of your 3 PCI slots. By simply adding a blower as outlined in this thread you can silently drop temps even more!

Why did you change the subject to a 6800GTO? Seongmin asked if the "6800 PCI E" in a Dell was any different from 6800 PCI-E from other manufacturers. It's not. Dell sells regular 6800s in addition to 6800GTOs.consumer9000 said:

Oops, misread the context. (Too used to associating Dell with the 6800GTO) You are indeed right that the standard 6800 is a crappy NV41.

Thanks for the info! This is just what I was looking for. And the link is a great idea. I currently have a sunon 80 mm case fan (pulled from an old comp) rigged below where yours is placed (amazing what some yarn and packaging peanuts will do!). It helps cool, but it is loud.
I'll take a look at the NV6800C3.
Thanks.

One other question regarding your Sunun blower mod. That blower is rated at 6.7 Watts whereas the Fan Mate sets a max at 6 Watts. Any issues with using that blower with the Fan Mate? I am assuming since you are running the blower at less than full speed it is not an issue? I guess the worst that can happen is that the Fan Mate would fry.
