the whole 5k series crossfire together...
from what i have tried and seen done..

good because there are only a few reference cards still alvailible the are all goin to the cost cutting crap with the fan in the middle of the card that you cant tweak the voltage on :S

No, only the same family of GPU's can Crossfire togther. E.g. 58xx with other 58xx cards. The only "exception" to this being the 5970 with the 58xx cards.

e.g. 5770's cant CF with 5830's, but they can CF with 5750's.

yet...you are wrong once again.
you can in fact crossfire them...but will it yield better performance xfiring a 5770 with a 5870...no, it will not. and it's also not easy to do, but can be done.
a 5870/5850/5970..yes, with little to no trouble.

You cant CF them officially, I'm not sure if there is a hacked driver for it or not however. That would be like saying X48 supports SLI if it did.

Thats entirely different, and its a dumb argument to make. ATI doesnt support it, period. Yeah, someone may be able to make a hacked driver for it, but the limitation is likely in the hardware.

Its like saying we can SLI a GTX 280 with a GTX 480 if we try really hard. In all likely hood, its just psychically impossible, and pointless to do.

They said we couldnt go to the moon. Does that mean we can go to Uranus? No.

There are some things in life that just arent possible.

  Not bad for ambient of 78F  1x 470

Nice run! What clocks are you running on the 470.

Success! I finally finished the chiller, and had a few hours to get some testing in last night. Thanks to the "get it colder" crew for all your help and pointers. (Especially Nate man!)  I put vaseline on the frosted areas discovered during testing, and it worked really well. Very little condensation on the dvi and sli connectors. Everything else was bone dry.  I actually didn't need the shop towel hanging out of the back of the gpu.

The chiller tops out at -26C when under load with 1 cpu and 1 gpu. This is the temp of the liquid in the cooler, not at the blocks. Using eleet it reports cpu at -23C, but I don't know what the cores are at...what's the best way to monitor that? Precision reports 1 gpu at -5C and one at 8C (I think that one is stuck, since it never changed).
 
Flow rate seems ALOT slower with the cpu block now in the loop, even at room temps it's just a dribble......well, it works @ -26C, so I guess I can't complain. I'm not sure what I'll find when I get the other 295 prepped and add that to the loop.

I spent most of the 2 hours benching trying to figure out this 980x cpu...only managed 4.8Ghz, which I'm not too happy about considering the temps. Of course more testing, testing, testing. I did manage to get in a few vantage runs (couldn't stop without first doing that, LOL!)

Here's the mess. No more pretty system Ah, who cares, temps are @ -26!  



Last night Hwbot was down, and I thought for sure this was the #1 single 295 winner, so I went on to other things. Dang, I'm still off 87 points. Oh well, more fun for another night.



I haven't run any physx-on runs with the single 295, so as the chiller was "warming-up", I thought I'd run one for grins. I bumped the cpu back down too.  Not too bad for the chiller being turned off 30 minutes before....liquid temps here started out at 17F and ended the run at 22F. It took 30 minutes to bring the liquid from -26C to -5C (22F) by continuously running vantage. I thought that might be the smartest thing to do rather than just turn everything off and go to bed. I ended up turning the computer off 35 minutes after I turned the chiller off. Liquid temps were 29F at that point.  I left it with 2 house fans blowing on it overnight just to be safe. 


Now I just gotta get that other 295 prepped.....and work on this cpu.

CPU was at 4.8Ghz (4788) @ 1.7 vcore.  With the limited time I had last night, I wasn't able to get the vcore down.  Before (on ambient water temps) I was at 4692 @1.74 and anything below that would not work.  At least I'm a little lower in vcore.  But, it's probably borderline @1.7 because I got a fair amount of BSOD 101's.

I'm not sure what cpu temp was during vantage...I never run those programs during the benchmark being that it might lower my score.  What do you run for temps?

Do you guys always run your benches with monitoring programs up? I have always thought that they would decrease the performance slightly...

Thanks for the clarification.

Yea, the same with anti-virus programs.  I don't find any difference.  People get caught up in habits....it worked once for them, so now they swear by it.

No, nothing on the foam tape.  Nothing anywhere.

Cpu score is starting to get insane

so a 470 is quite a bit lower in performance over the 480...WOW!

Yes I would say so, probably has a lot to do with less power available besides of course the lesser specs.
This card has not gone over 63C during vantage runs. Much better than I expected.
May not be a 5870 killer but a very nice card anyway.
Will see what 2 do next week.
Not done pushing this one yet.

what did you get when you ran heaven 2.0 extreme tessellation?
