yup not completeing canyon flight is a definite sign one of your cards is dieing.....mine also wouldnt finish canyon for a few days, try after try I had to keep lowering clocks till it finally died .....my rma comes tomorrow.

Good luck!
I'm having su much trubble with 2900 CF on subzero that I might go crazy before I get a complete run in 06 with everything under ln2. The first 30 mins on the first try everytihng worke great and I had 1050MHz working. I am sure now that one of the cards is damaged, that is the reason to why it wont overlcok anymore. I will go out and buy a new one tomorrow.
This is a few days old screen showing the potential of 2900XT CF in 06:

Nice this SM 3 score.. Share more when you can.... GT1 is allways benefits to Nvidia cards ( it was same with the 7900)...
This should give a pretty good idea on what to expect (NOTE: it is by no means a fully optimized score, no PCIe clocking, no OS tweaking etc):
watercooled 2900XT CF w/ 2 CPU cores vs. LN2 cooled 8800GTX SLI (older drivers) w/ 4 CPU cores (and slight CPU clock advantage for the nV rig also - 4876 vs 4804MHz):

Means that 4 cores running at 4.8GHz (CPU Score of 7000+) with watercooled 2900XT CF gives you 24k already :D
The 2900 XT benching will continue at DreamHack on Saturday, a new 2900 XT, a motherboard I'm not going to reveal just yet and many, many liters of nitrogen :D

1200l :D
haha that should give you enough time to really tweak the settings. The results will be amazing for sure.
First decent complete run of 3dmark 06. I was so excited that I took the screenshot wrong :)

Omg isn't that a WR :shocked: :slobber:
Hoho!! NICE! :up:
Still some MHz from max on the CPU I guess... How about the GFX, possible to get it higher?
No Vince still has the WR :) I think these 2900 will give him and Ultra SLI a honest fight though :D
This is just the begining. System perf. is terrible with this low FSB on 975X. If Blitz with DDR3 works well I think this can be a very deadly combo.
I have 12 liters of ln2 left and I will go for 25k++ with 4950MHz with the same GPU power tomorrow. There is alot left in the 2900's, A LOT. 1050MHz is with -55C and 1.35V.

*biting nails* I can't wait until we get these babies really going :D

You make it sound easy :) I must say this have been the most challenging benching I have ever done. P5W DH and Kentsfield with handicapped overclocking of 2900XT Crossfire is a very very bad combo. Combine that with three pots to run with ln2 (I have two cascades thatdoesnt work). Cross your fingers Blitz Extreme will work like a charm and new 2900XT to replace the bad one that barly works will fix that problem.
12 liters of ln2 brought me a score of 24880 today with 4900MHz Kentsfield. I saved screens and saves to my USB-stick as usuall but for some reason the files didnt "stick". The screen below is the only one I saved to the HDD by mistake.

Too bad about the non-sticking file, but now you have to do it all again and you might as well do it properly, wich means +25k. :D But I guess that will have to wait a few days...
I did not thought the X2900 would do so well in 06 actually. Great result!! :toast:
Yes crotale and I will be benching on Dreamhack with ASUS in a few days. I think we will have penty fun there as usuall even if it turns out to be a disaster result-wise.
Neither did I, thats why I have been giving it this much time and effort to prove to myself and others that 2900XT Crossfire are truly powerfull even though its flawed in the ability to overclock.
