*Official* ATI Radeon HD4850X2 Thread

[rico2001]

3.5G is perfect and I wouldn't try for 4G. The thing is at 2.66G, even an i7, would be lacking a little. 3.2-3.8G dual core or quad core seems to be the sweet spot for pushing a X2 or tri-fire.

I didn't know this was such a popular card. I was thinking about getting it for the quad DVI-D. How are the drivers?

Hi Rico,

I found your thread by searching google. (actually im new to overclock.net)
Sorry for my bad english.
I currently have very old set up.

Core 2 Duo E6700 Oced to 3.2ghz
mobo: abit ip35-pro
PSU antec 650watts
4850 x2 2gb

When I first got my 4850 x2 2gb, I wasn't sure I wanted to keep it because it was way too loud for me.
I was wonder if zalman vf900 video card fan will make my card silient and cool?

I know my cpu might bottleneck my 4850 x2, but I am saving my money to buy good mobo and cpu. Any suggestion on cpu and mobo for 4850 x2?

I might plan to add another 4850 for tri CF in the future.

Your suggestion will be appreciated! Thank you.

Well I never though the 4850 X2 was too popular. Although this thread is huge, not many people have this card. Most went for the 4870 X2 and now a days the very popular 4890. I always thought this cards was cool b/c it is 85-90% the performance of a 4870 X2 and cost half as much. The four dvi's are cool as well. This cards runs a good 20C cooler than its big brother the 4870 X2 but can be on the loud side. The drivers are rock solid, all issues were worked out 5 months ago.

Hi krazyatom, welcome to OCN and the 4850 X2 owners thread. And btw, this is not my thread, it all 4850 X2 owner thread. I just try to look after it and give advice when I can. Shame you find the card too loud, some people do. I don't have the zalman VF900 cooler on my card so this is an area where I can't offer any advice. I believe they are quieter than the stock coolers but honestly could not tell you. You can ask OCN members and 4850 X2 owners, legend999 and SigSauer. They both have has that model zalman on their 4850 X2 cards. You can also look through the 175+ pages on this thread, I'm sure their temps and sound level desciptions are in here somewhere.

edit: any of the E8xxx or Q9xxx cpu would do great for the 4850 X2 or any other card you may be thinking of.

[MrMan]

do they make aftermarket coolers for these cards? are they quiter than the stock? i dont really care about temps.

[SigSauer]

Not specificly for this card but Zalman VF700/900's will fit and there the XSPC Razor 4850X2 watercooling block aswell. The zalmans are somewhat quieter but the new bios update from sapphire makes the card pretty quiet.

Drivers are the default ATi ones.
To use the 4 DVIs you might have to disable Crossfire.
Resulting that the 3D performance is at the level of a single HD4850.

I recently sold my 3 HD4850X2's and not been in the list ;o)

OC potential just sucks.
The Voltage drops to strong when both GPUs are under load.
Sapphire did save to much in the board design...

Disable crossfire to use more than 2 displays?! That kills the deal for me
