*Official* ATI Radeon HD4850X2 Thread

Do you think that it being backwards makes a difference. I know with my motherboard I have to put the card in the 1st PCI-e slot, b/c it runs at x16 speed, like 8.0 Gb/s, I believe, then the bottom slot only runs at x4, but it looks the same. I know this is beginners stuff, but I just want to help yah. I do not know about your older motherboard.

Hey,

and sry that I'm too lazy to reread all 103 pages.
But is there a way to higher the limit of the Core OC in CCC?
It ends at 700 with this Card while my 4870 goes to 800...
My Card is watercooled - so temps are less of a limit!

Or would you recommend a different Tool to OC and if which?

Use rivatuner, thats probly the best thing for it right now. Someone needs to mod a signature for this thing so we can get higher clocks in ccc.

Side note, I fixed my tri-fire or sound card delima. I put a zalman vf900cu on my 4850. It gives it a little more clearance and lowered the temps roughly 16c degrees.

Ya right now the easiest way to do it is with rivia tuner although your not going to get much higher than 700 mhz because the voltage is restricted on this card so if you want to risk your hardware and get higher clocks you either have to flash the bios and increase the voltage or do a volt mod you might get lucky and be able to do anywhere from 720-730 without volt moding it but if your looking for a higher clock then that you should do a lot more reading on doing a volt mod.

finally i went over board 20k with this hell of a card with just 3.7Ghz.. sweet!!

Thanks for the answer.
So you also say that the X2 Cards wont reach the OC potential of a normal HD4850 because it get's unstable?

I'm not going to Voltmod the Hardware.
Haven't searched about soft-Mod in BIOS yet - cause I think I'm not even do that.
The only good I have is that I put 2 water blocks on that card and can keep it real cool^^

wow what kinda of overclock you got with that rig? you almost got the same score as me with my trifire. thats freakin nice man. Please tell me your cpu clock, mem clock and video cards clocks.

Setup:
CPU: 3712 225x16.5 VCORE: 1.43v MEMS: DDR2-1200 @ 2.35v Team Xtreem
VGA: HD4850x2 700/1130 per core(modded bios)
NB-HT:2640@1.4v HTVOLTAGE:1.38v CPU-HT: 2000Mhz

i raised every voltage settings just to get this stable on Vista and Win7..so far Win7 has a higher score thats why i am leaning to it..

I was able to pull this off with the card set to 700 core clock and 1120 memory clock, It was not artifacting in 3dmark06, but in Crysis and Crysis Wars it will within 10 seconds on this high memory clock, but it is fine in all other games. I can oonly get a stable memory clock for Crysis/Wars of 1040mhz, and 1050 with a 685 Core clock, so the memory shows that it is fine when 3d marking, but bums out quick in Crysis.

@Shroom
See those Zalmans seems to be working out for yah, I was also able to cut my tmeps about 10 degrees with taking the metal fan guard off, moving my card down to the last PCI-e slot, and putting 2 140mm Yate loons on the bottom of my case, about 5 inches from the card, and it seems to be working well for now, heres a pic.
