It's taken me ages to get them to work, i've tried 4 different driver sets, uninstalled sound drivers reinstalled them, pulled my hair out then finally turned off afterburner and now after a month of searching forums and tinkering they finally work!!!!

I've got BC2 absolutely maxed HBAO on, AAx8 AFx16 at 1680x1050 and it runs like a dream - better than i'd hoped for!!

YES!!!!!!

No need for me to upgrade until the ATI 28nm chips come out!!!

Result!!!
 
Hmmmm

Nice one. I too have a 4890, have been thinking about buying another one but haven't felt it was necessary. I play at 1920 x 1080 and nothing makes the 4890 struggle so I thought I might wait a little longer.

You're right though, I've been looking through the benchmarks and crossfire 4890s is like always near top of the list. Glad I got chose that and didn't wait and end up getting a 5770 or something - 4890 rips that to shreds imo...

GJ mate- got any FRAPS for us?
 
i'll do some tomorrow when the gf is off selling stuff at the flee market.

I'm playing with v-sync on - as i don't really like tearing - and i don't seem to be dropping any frames do i reckon i must be averaging over 60. Slows down a bit with explosions, but it's great being able to play with such good IQ.

I only really play BC2 and a bit of L4D2 (which it will eat alive - no pun intended) so i'll do both of those
 
Well depending on the rest of ur system, you should get about

70fps with: 1920x1200, 4AA, 8AF, High Quality, DX10 in BC2

and 153fps with: 1920x1200, 4AA, 8AF, High Quality, DX10 in L4D2

I'm gonna bookmark this thread so I can pester you RE: the settings. Didn#t realise it was so complicated, is it just the 4890 that is awkward?
 
Snap !

I did the same a month or so ago. Unlike you I had no problems setting up the new card. I uninstalled the driver, installed the new card with two connectors and reinstalled the 10.4 driver. Hey presto it worked perfectly first time :)

For the money I don't think you can beat 2 4890's right now. Excellent value and you don't have to bother with those expensive 5 series cards.

The 4890's handle everything out there.

Congrats on getting it to work. I'd be seriously unimpressed though if it didn't run like a dream at that res with basically the firepower of a 5870.
They should last for a long time at that res. :)

It should be with 1600sp's. X2 cards or crossfire/sli usually allows you to skip at least 1-2 generations before they start to get slow. ie. 4870x2 trades blows with 5870. The current 5970 will probably do the same to the next lineup we get.

And arn't the 5770 and 4890 both 800sp parts? the only real difference being the 128 vs 256 bit mem interface. Not really going to 'rip it to shreds' then.

At 1920 x 1200 the 4890 is usually 15-20% faster. 'Rip to shreds' might be an exaggeration, but 20% is still quite a lot.
 
i had a lag problem in BC2 which got mixed up in the whole setting of it up...

I was playing on the beer drinkers server last night and was suddenly getting no lag - i realised i had afterburner off so stuck in the other card and it worked perfectly. I was pretty over-excited when the option for 8xaa came up.

I bought the 2nd card just for this so super pleased it's now working.

I'm on the 10.7s and 26th July profiles.

GZA - i'm running a i5 750 at 4Ghz 4gb of ddr3 at 1600mhz
 
What do you need to know scougar?

Putting in the 2nd 4890 was literally that easy. i put in it then connected the bridge and turned on the computer.

I set clocks to 900/1000 in afterburner, then turned afterburner off.

Clocks still show in CCC but i don't get the in game lag i was getting in BC2 with it on.

I really think all the laggyness i was getting was due to afterburner and on reflection it was afterburner that was the cause of all the problems i was was having with BC2 and not crossfire.
 
Yeah, that's what I was asking basically, as you said you spent a long time sorting it out, then to find it was actually something simple.

I thought you would have tried it in crossfire without afterburner initially though? (which is the bit that confused me if it was that simple).

Thanks for posting Appreciate it :-)
 
i guess i was just eager to get it to work...and i'm sure i did try it without afterburner - though i did have to alter the clocks - one card was a vapor-x so i had to downclock the memory slightly - so maybe that was the one thing i didn't try after all.

Having said that i'll go home tonight and put afterburner on and try to re-create the problem...

there's always a chance dice fixed something in the recent server patches for BC2 (a slim one i know!!)

Congrats! This is exactly what I would do but sadly one of the PCIe slots on my board refuses to run at anything other than a link width of x1! Both slots are x16 (allegedly). Nobody seems to have a fix for it either, I tried everything I could think of, read about, rumours, hearsay :rolleyes:

Any new suggestions would be rgeatly appreciated though but I think the PCIe slot is just wonky, Gigagbyte support was totally useless, after trying all suggestions and BIOS tweaks etc. etc. Gigabyte said... 'update VGA drivers'. Oh dear, back to ASUS next time I guess. Damn shame, I'd really wanted to give Crossfire a shot.
 
i don't have the computer on for that long to worry about the juice to be honest, i do most of my web browsing on the laptop.

PC is for gaming/encoding
 
As a side but related note, is it possible to confirm, if one is running bfbc2 in dx11 mode?

Becuase I recently upgraded to a 5870, and changing the graphics settings from medium to max settings, I cant really see much difference.

Iv also gone from DX10-DX11, with little to no visual improvement at all.

The only noticeable difference I can see, is that things like rocks are pre rendered at high, rather than rendered as you walk past them at medium..
 
opeth i'm sure those differences are there. maybe you should stop playing for a few days and look again with fresh eyes, or play something else then come back.

Nice card btw - i nearly bought a 5870 and was looking seriously at buying raven's on MM before i got my 2nd 4890 working.

As someone on one of your other threads said - just play some games and enjoy it!!
