shoul cut donw a frame or 2 at most at minimal, but at average still will be quite ok not noticeble..... the bottleneck mainly on the data transfer between cards only.

thx i just found out that my 1st pcie slot with x16 mode and 2nd pcie slot with x4 or x1 mode

Arrghh, hands itchy wanna try 3870x2. Anybody here use it?

i also love to try x2.. but i've a 9600gt or possibly 9800gx2 coming up.. hopefully..

well i try x2 3870 u try 9800gx2. and we compare

if i run cf with my mobo with 2nd pcie slot 4x speed isit better dun cf or wad

recommended to run at least 8x 8x.
mine is not bad. i dont see any real difference wiith my old mobo 16x 16x (790fx).

err guys..got some prob...about the fan

on auto setting(monitor by GPU-z)...when the temp reach 80'....the fan should run at 70% of it speed rite....the prob is only the GPU-z said so...the fan at the gfx still running at lower speed...how to fix this...

i have to set manual 70%...cannot set auto...if not the temp will reach 90' on load...coz the fan still running at lower speed no matter what's the temp...not following the rate it suppose to be...

auto > idle 57-58 load 87-90 (CPU-z show the fan running at 85% but actually not...no noise at the fan n silent)
fix 70% > idle 43-45 load 63-65 (i can hear the noise of the fan running at high speed)

the card already flash by fix bios (10.071)...still same...is there any latest update bios??? I found 10.077..anyone test it??

Those who wan CF 3850 or 3870,i suggest wait.
Wait for HD 4xxx series coming in June.
Btw,this card i still cannot afford.
Lets see how much will the 4xxx series cost

i am oso using p5k deluxe .. now facing some probs with it .. not coz of gfx card laa .. hehehe

3870x2 will cover 4 of your 6 SATA slots on the mobo ..
3870 (dual slot) will oso cover 4 of your SATA slots ..

i have to say the current 3870 drivers are not entirely stable just yet .. i had to downclock my OC version (ASUS TOP) to play some games ..
dunno if it is just ASUS TOP version or other manufacturer OC version 3870 oso facing same probs ..

as for 3870X2 .. i have to say it is just WONDERFUL .. altho drivers for it farked up .. it still did its stuff wonderfully well
just wait abit more for the drivers to be nice and stable .. then can consider liauu .. hehehehe

i hv no problem using latest driver for my OC version card..

hmm ... mine screwed up ... so i sold off the card liau now .. hahahahaaa
wait another couple more months maybe go jump onto the X2 wagon ..

hehe finally manage to test this new card from AMD.. hopefully can have its nvidia counterpart soon..

AMD Radeon 3870X2 from Sapphire




the bundle.. nothing special


quite long, around 8800gtx length.. but still not as heavy as 9800gx2






8pin pci-e + 6pin pci-e. the 8 pin pci-e is just to enable overdrive and to allow CrossfireX

back view..


ddr3 only


standard backport.. no direct HDMI port like 9800gx2..

test & oc

CrossfireX test..

Sapphire 3870X2 @ default
Sapphire 3870 @ default (thx to flatfinger)

Gigabyte P35T DQ6

the result is quite poor might bcoz of my p35 board that does not has dual pci-e x16 lanes and also pure pci-e 2.0.. and also bcoz of immature driver..

we've tested by oc the 3870x2 to 875 / 950 (from 825/900) and the increase is only 22 marks..
