Radeon HD 3850 CrossFire & 3DMark06

Hi everyone,

Me and Kinc played a little bit with Phenom 9700 system in Poland, Warsow. System was based on Gigabyte 790FX motherboard and there were two Radeon HD 3850 graphics cards installed in CrossFire mode. Corsair's DDR2 memories worked at CAS 5 setting and OS was Vista 32-bit. System was definitely not tweaked at all or optimized for decent 3DMark runs:

Phenom 9700 @ 2912 MHz (1,45 V) and Radeon HD 3850 CF @ 750/999 MHz.

More results maybe next week from my own lab.

PS. Here are couple other of pics from the event:

Good advices for overclockers from Richard Huddy.

nice results!

sampsa long time no see

great scoore

not bad for an gaming system i guess.....

R680:
3870 X2 in CF working properly is good news for people on X38
platforms.....:)

where can i get those funny "dating tips for geeks" slides ?

Sampsa how you liked Warsaw? Any night trips?? :p:

On a serious side any hint on QuadCF score?? :)

Its probably the new WR :rolleyes:

Wow Phenom clocked at almost 3GHZ on air. Thats very good for AMD on there 65nm process.

Nice score on new HD gfx :) Overclocking in CF mode still with problem's ?

Four cores at 2.9GHz and 1.45V with this Akasa cooler - not heat :rolleyes:

And ... what about Poland ? When We see some oc competition with World Legends in Poland :D

Hahaha... :rofl: :ROTF: Those two slides are funny, results ain't too shabby either :yepp:

Overclocking now works like a charm in CF. Hopefully ATITool and Rivatuner will add support soon because Catalyst Overdrive is not my favorite oc tool. You can also plug in Radeon HD 3850 and Radeon HD 3870 in CrossFire X and even overclock them separately. Also Overdrive for 790FX chipset seems to be quite neat tool with voltage, frequency, multiplier and memory setting adjustments.

Yeah, slides are cool. :)

Thanks Sampsa, it's good to know ATI finally supports CF overclocking. Man it's been awhile since I've seen an all ATI rig in the Team forum...now ATI, let's see working tri-fire.

nice.. so even 2900XT CF oc'ing is supported ?? or just for 38xx series CF ?

what board supports QUADfire?

Bit lower than legit reviews got with a 3ghz yorkfield and stock 3850 CF :( Any chance of running again some day with a 3ghz phenom?

hah gotta love richard huddy :D
i only found out i lived in the same tiny town in the uk as him for a year after i moved away :doh:

thanks for sharing sampsa!

All boards featuring 4 PCIe x16 slots and based on AMD 790FX chipset.

Considering the fact Cod4 only supports dual card option would you even notice the increase with quad vs crossfire ingame? Curious question..

"Value Segment" had me lol'ing

Hello Sampsa just wondering like eva2000 is wondering is the 2900xt in CF oc'ing supported also? or just the 3800 series in CF?

I ran it in Warzaw with a 2.4GHz phenom and the result in 3dmark 06 @ 25x16 4xAA/16xAF was pretty impressive @ ~14k. It was the same as defualt settings actually wich proves scaling works.

That is impressive.

How are you finding Phenom? Much leeway in clocking?
