now let me post my single and CF results..
Rig spec:

Q6600 @ 4.01Ghz
Gigabyte P35T DQ6
Kingston HyperX DDR3 1375mhz @ 1426mhz 7-7-7-24
Corsair HX620watt
Sapphire 3870 Single

3870 @ default:
[attachmentid=352590]

3870 OC @ 891/1314:
[attachmentid=352591]
Rig Spec:

Q6600 @ 4.01Ghz
Gigabyte P35T DQ6
Kingston HyperX DDR3 1375mhz @ 1339mhz 7-7-7-23
Corsair HX620watt
Sapphire 3870 Crossfire

3870 CF @ default:
[attachmentid=352592]

3870 CF @ 820/1250:
[attachmentid=352593]

referring to those results i think 3870 CF pawned single 8800 ultra.

Nice result to share.

ya, it just base on 3dmark score, but when in real game nvidia perform better even 2900xt cf score more then 20k, but when turn in game ati loose, just waiting comment @ post from who hv play game on 3870 crossfire, wanna know did it perform better then sli

g0od jobs bro

but still the 3870 CF score kinda lower i believe compared to 2900xt CF which can get 20k score of 3dmark
ps: i thought the 2900xt default memory was 2Ghz aite?

It's because of the motherboard. The P35T-DQ6 does not offer dual 16x PCI-Ex 2.0...Maybe should replace motherboard with X38 or X48, when there's enough resources for that.

Added on December 2, 2007, 11:43 amAnyone up for setting Dual HD3850 512MB CF-X? I surely want to see the results as HD3850 512MB seems to be the card that offers the best bang for the buck at the moment.

good score, bro any comment while playing games? how the fps? if wanna compare to 8800gt sli

i've just tried crysis and when i asked it to set the graphic to optimal setting, it just detect it as medium spec..
so to make it comparable with my previous 8800gt, where i used high settings, i manually adjust all the settings to high, 1920x1200 and no AA.

specs:

Q6600 @ 3.2ghz (400x8)
hyperX ddr3 @ 1333 cl7
p35t dq6
3870cf @ default
xp sp2

Q6600 @ 3.2ghz (400x8)
hyperX ddr3 @ 1333 cl7
p35t dq6
Single 8800gt OC @ 700/1750/1800
xp sp2

using fraps to monitor,

avg fps for 8800gt is 26 while 3870 CF is 41..
lowest fps, i notice 8800gt only drop to 23 while 3870 CF drops to 33 (almost 20% performance drop compare to 8800gt 12% ) ..
highest fps 8800gt 31 and 3870 CF is 46

wow..it doesn't show an impressive result on CF setup, like 8800GT SLI...imatuer of driver?

this is such a silly statement.

one that is an impressive result
second nvidia game without a mature driver for sli??...

anyways this is a overclocking thread dudes..
not a discussion about HD3870 vs 8800gt.
or even the performance
this is what i can tell u about the bios

using the stock bios.. even though u cant go more than 862.. but it was gaming stable 862/2500 easy.

with the new bios that overcomes the pll divider... the mem u can overclock so much and very buggy with CF.

Sapphire 3870 new bios :

1. fixed the 862MHz limit.
2. fixed bugs of the fan speed from always 25%-25% to 35%-50%.

The latest 3dMark06 world record still using HD2900XT.

how's the temp compared to the factory cooler?

rlhc, try this !

my ati 3870 with fitted with TR-03
This is my 4th gfx card that been using this cooler from NV 7900GT - ATI 1950XTX - NV 8800GT - ATI 3870 &.................

TR-03? Is it Thermalright HR-03?

Yup..........Thermalright HR-03

sukhoi core clock madness..........

mine 3870 stock fan speed also very scary on full load, 92oC @ full load...... incredible...but after pushing the fan speed to 60% quite ok it turns out to be, full load at around 60oC only

Thermalright HR-03 and the newer HR-03 Plus is a 3rd party cooling solution...the brand is Thermalright. You can see it first hand at PC-Zone at Lowyat.

Quote frm Topic Title,

Got CFX benchmarking??

my fren had a abit ip35 pro board and tried xfire 3850...he got 8k score for 3dmark06....for single card he already got 7-8k liao...wat is happening? bios problem? i aware his 2nd slot is 4x...but still the result wont be that low

i wonder why the score seems a bit low for crossfire.. neway what is his result with only single 3850?

i wonder why the score seems a bit low for crossfire.. neway what is his result with only single 3850?

my fren single card get around 7.8k....we put the xfire bridge ma...need put 1 or 2? we put 1 only...i also just put at my maximus

Only one bridge is required. I'm just being lame and silly.

did the 3870 comes with the x-fire bridge?
