i just wonder 2x 3870 CF or 3870x2 is better?
*
this is the best latest review that i could found...thx to sniper actually....focus on this 2 card; ASUS EAH3870 X2-1GB n AMD 3870 Crossfire......in 3dmark u can see the x2 slightly better than the xfire...but in game performance show the different although the conclusion recommended x2...the xfire do much better actually in HD....

The review link

most of d review doesn't compared clock to clock, so they mite be bias. do note that there are diff in core clock & mem speed for both, some more 3870cf is of dd4, d x2 uses ddr3 only. unless there are users with both 3870 x2 and 2 x 3870 do comparison clock to clock w/ same bandwidth as well (cf @ 8x), else it's kinda hard to judge which is faster.  sweat.gif
*
ya..agree with u...most of the review comparing them with different clock...if same clock...i do have a sense of xfire can do more better...dont know la

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??

How to test how high can it go? Need to add PCI-E voltage or anything?
*
only by increasing core n memory of the card...other is default n no voltage mod...should pass 3dmark bench....mine can do 890/2600 but it will read 877/2592 only...score 11600+ proc limit...not so good...since irenic can do 891/2628...

Currently I am using a single slot Sapphire HD3870, and i notice that my fan speed doesn't go down even when on idle.

Is this a normal behavior with this card? Do I have flash with the infamous fan fix bios? My current BIOS is 010.078.

on GPU-Z...thick the box..."continue refreshing this screen bla bla bla"...try to see go different or not...or monitor it using rivatuner...if same...
then try run atitool with 3d View...as the core temperature going up...see the fan going faster or not...vice-versa...close the 3D View...the core temperature going down...the fan speed decrease or not...(refer to Post #789)
