I think that my pc is running crossfire,but am not sure,so please give me some help.

In GPU-Z i see "Enabled (2gpu's)" ,in CCC tab "crossfireX" also,but in CCC "Graphics Hardware" i see "Primary Adapter" but the second one say's
"Disabled Adapter" ,so who am i to believe.

Is this a normal score for crossfire,see sig.

3DM06,16360
3DM05,22683

Notice any difference with one card installed?

I will try this today,thks

Here are the 3DMark's,

CPU@stock + 1x 3870@stock

3MD03=36061
3DM05=19697
3DM06=12464

CPU@stock + 2x 3870@stock

3DM03=60483
3DM05=22683
3DM06=16376

As you can see the only score that is a big differens between single and CF is 3DM03,the differens in 3DM05/06 @ single/CF is not that big,or is this normal.

that is normal, 3D03 is a very GPU related bench, 3D05 and 3D06 are more overall system related.

what's important though is games; are they quicker?

RocKer · 13th April 2009, 20:14

Ok,so the score's are normal,i will play soms games,if i have time

.

I try'd 3DM01 also,the differens between single and CF is not that big,

Single=56749
CF=58098

But that is also normal i think,is it.

Thks for the info

3D01 is completely CPU related with newer video cards, HD 3870 is considered ultra high end of a benchmark from 2001

3D01: sees as good as no improvement from more VGA power (+2% going to CF)
3D03: is extremely GPU dependent, biggest boost (+67% going to CF)
3D05: more CPU power dependent, VGA still plays a role (+15% going to CF)
3D06: more balanced between CPU & VGA, bigger boost than in 3D05 (+31% going to CF)

try Far Cry 2 build in benchmark or other game to get a real idea of performance increase

Sum of FPS Benchmarks 1920x1200
486.30 402.20 --> 20%

Sum of FPS Benchmarks 1680x1050

Score in FPSGo 513.40 464.90 > 10%

Quote:

Sum of FPS Benchmarks 1280x1024

Score in FPSGo 536.30 539.50 >> -1%

so best to stick to nice high resolution with lots of AA/AF to get the biggest boost

FYI a single ATI Radeon HD 4850 is faster than two HD 3870 VGAs

riska does better, 1268Mhz GPU: http://hwbot.org/result.do?resultId=731802

On h2o that's impressive. These cards can go upto 1400MHz gpu with LN2 and the right voltage mods
