I'll probablly run at these speeds. My memory is right around 900mhz. This score is with a 512mb 3850. I think I have the CPU voltage a bit on the high side too..

Yeah, 3dmark stable anyways. I ran Orthos small fft's for only about an hour stable. It never crashed or hiccuped on me. The Xigmatek cooler is pretty darn awesome at keeping my cpu cool. I have no way of monitoring cores for some reason, but the CPU temp has never gone above 41c under constant load. Hey, do you know of any way to decipher the serial number to find the date of manufacture on these chips? AMD puts no info about the chip actually inside the box on the carton anywhere.

CoreTemp, isn't showing your core temps?

I have broken core thermal sensors on my chip. AMD Overdrive can't even display my core temps. It's fine with me though, with AMD all I care about is CPU socket temp. Since this chip is very nice on the voltage and speeds, I'm not going to complain about not reading the core temps. I'm getting rid of it the second I get a Phenom anyways. So far, without benching or stability testing, I'm pretty sure the highest I've gotten is just above 3.5ghz and in the high 1.4v's.

*Oh and I found out the date of manufacture was the first week of March 2008.

Hi guys

Back when, Catalyst 8.3 was released I had a chance to play 3 way CF w/ 3x3870 & 2 boards, MSI K9A2 Plat. v1.0 and ASUS M3A32 Deluxe plus Phenom 9500, in Vista x64, I was able to have 3 GPU CF in CCC enable, but 3DMarks06 score was worst than just one 3870, tried different vga bios, setups, even connecting 2 CF bridges on the 3 GFXs by crossing the bridge from 2nd card(1st slot) to the 1st(2nd slot), never worked...
Some one said it's driver related, now we have Cats. 8.4, but I don't have the board's (replaced for the DFI LP UT 790FX) and one of the cards, so can't try anymore.:(
Sincerely I hope that you can make it work.

Be well...

Overdrive doesn't see my temps either :confused: Never had

Some results...

Ok, so here we go. For all of the tests the processor and RAM were all clocked identically. To start off, a run with a single HD3850 512mb card:


Next, I went on to run two HD3870's OC'd in crossfire:


The final step I took for tonight was putting all three together. Notice the way I have the crossfire bridges connected. This is the only way to get CCC to read all three cards at once.:


Obviously, I'm very limited by my processor. I will do a couple more tests and add them soon (Single HD3870 & HD3870 + HD3850), but I look forward to getting a 9850 Phenom soon to see how the results fare then.

nice...the phenom will help the bottlenecking lots...my score went from 10800 to 11382 with my 9850BE...and its running at stock speeds (cpu) but 2 and 3 cards should be scoring lot higher than that...if my single 3870 can do 11k

I'm pretty sure with my 3870 run I got just under 11k so it's all seems about right. I'm just suprised that CCC actually saw all 3 gpu's and ran it effectively. Now if I could only test it out with my Q6600 then we could really see what's up, but it will be a couple weeks for the Phenom yet...

as impressed as i am looking at the rig, the fact i can break that with a single 8800GT makes me wonder just how much CPU power you need to run crossfire...

so the 2 cards in crossfire = 3 cards in crossfire-x :D

please try to run 3dmark vantage

also you put 6 fans on one radiator, that is idea will be more sound from fans that will cooling.

a fan don't need a turbulent air flow on him, because that incoming air flow will hit the fan helix and that will case noise and vibration, also will influence the speed of the fun.
two fun mounted like in you system will not have a double airflow

the first fan will have from were to get the air.. but after the air run in the radiator to the second fan will have a decrease speed and will be hotter that initial temperature. the second fan dont have same open like the first because have mounted in front an radiator.

in case of you I don't see necessary to use 6 fans on one radiator, even at low speed

you use more power to run the fans that you will do with 3 fans on one radiator

:)

but... you don't want to save the planet :D
