awww im so sorry but i cant tell you more right now for the reason i dont have the card at the moment... ill tell you all about it when ill get it.

 

[Tatty_Two]

oh no this isnt a regular HD5850, it does 930MHZ on stock voltage. ill review this GPU later this week or next week.
ok it is a regular HD5850, ull see soon what im talking about

Mine does 940Mhz genuinly on stock, that was my point, that is not always an indication of final speed/volts sometimes the jump from 940 > 1000mhz can still need a high jump in volts just for that 60mhz..... not suggesting your "special" chip won't do more.

Same here. Stock volts will get me to 940mhz, 1.21v is needed for 1ghz. Oh, and I vomit in the general direction of your avatar.

5870's Problems. I have two 5870 XfX one is the xxx edition that that was made when the 5870 came out overclocked and the other is the new one that is short and has base clock I'm running them in Crossfire (i have set both speeds under-clocked identical). In Battlefield BC2 i get flickering and a black screen that shows everything but the picture ( i can see the sights, words, but no picture) and sometimes the game just shuts down completely. I have all the latest drivers for board, and catalyst. But nothing seems to work even tried older drives. Any thoughts on this would be great thanks fellas.

 

[crazyeyesreaper]

roll back to cat 10.4a if u can find them or manually edit the games ini file to run dx 10 mode

Make sure DirectX is up to date and make sure you have all of the necessary Microsoft Visual C++'s. If that fails, reinstall the game. Catalyst 10.7 works fine for me with BFBC2.

 

[Jflynn0]

Will try that i have reinstalled window and the game but did not fix problem i will go thought and manually intall direct x and C++ to see if that works. The game works fine with one card just with two is when the problem starts

Make sure you are using both CrossFire bridges as well. In CCC it does say that CrossFire is working and all that?

 

[Jflynn0]

yeah does say that crossfire is enable. Im only using one bridge right now will try two see if that works. The direct x install didnt work. will try the c++ also

 

[cadaveca]

Yeah, no issues here with 5870 Crossfire and 10.7, with BadCo.2. I do have some overheating issues at times, due to a dying fan, and the odd CTD, but the CTD is pretty much server-specific.

With one bridge, occasionally the screen will go all black, but I can still see HUD interface...it's pretty funny.

I've even gone back to 875/1300 bios, and only have issues with multi-screen.

The key thing for me is heat...it almost unbelieveable to me that the stock fan profile allows the cards to overheat, but it does. The cards will be in full throttle before the fan even gets to 65%.

 

[Jflynn0]

yeah the black screen with hud is what is happening about once a game. Cards reach about 74-77 under load. The older cards with the fan on the end are quiet the one with the fan in the middle is ridiculously loud at 55%. I am using dual monitors maybe that is the problem. But cards are not overheating to a point of shut down can i have clocked back to 800/1100 so see if that solves problem but it didnt

the special thing is that this HD5850 costs like any simple HD5850.

Get that second bridge back on, and if you have STEAM version, have it scan the game files...

My cards hit 93c and 95c respectively. Fan @ 100% gives a mere 9c drop on both cards. And hurts my ears.

Put a 98CFM fan blowing on them, their fan noise covers that huge 38mm fan's noise, even, and then things are OK depending on ambient.

Damn dude, those temps are crazy bad. Did XFX ever get back in contact with you?

 

[cadaveca]

Yeah, basically said what I figured they would. I gotta update that thread. I got an email from them late friday, but was ahving issues with email last week due to ISP problems....

Once ambient is above 26c or so, I'm screwed. I just can't get the heat out of my house fast enough, and I'm not about to buy an airconditioner just for the pc(I just can't do it, health reasons). I've even ducted the hot air form the pc directly out of the house, but radiant heat when the cards are 90c+ is just too much to deal with. It's acutally stupid, because although my cpu is quite hot too...it works just fine, but it's fan screams @ like 6500RPM. The vga cards just crap out.

But I found that I was gettting artifacting on 900/1250 XFX bios, so I swapped back to 875/1300, and the cards work OK...gotta keep temps under 80c though.

 

[brandonwh64]

damn cadaveca! that sucks about your cards. i have a visiontek (which is spotty on warrantys) and this 5850 never gets over 68 deg full load with kombuster with fan on 50%

 

[dj-electric]

how do you ppl let yourself use Kumbuster and Furmark just like that?
i mean.. those softwares have already killed some GPUs

 

[cadaveca]

I've only run the furmark bench a couple of times. I know that those tools don't really test vga ram, so they are useless to me, personally. Howver, some ofthe 3DMark tests generate the same sort of load characteristics, so the cards shoudl be able to handle it, I think.

 

[brandonwh64]

doesnt hurt any of the GPUs i have used.

Ive used it for hours on many, many cards OC or not and they still run like they did when they were purchased

 

[cadaveca]

brandon, it also depends on what driver you use. there is a profile within driver that lowers the actual work done by the gpu when using those tools. I bet a simple rename might get you another 20-30c on load...


But with thta in mind, running it should be perfectly safe, as long as you don't screw with things.

 

[Jflynn0]

thanks fellas looks like the Second Bridge connection work just play a few game of Battlefield BC2 and had no black screens at all or crashing. I thought the second bridge was not needed in crossfire set up what is up with that.

 

[erocker]

Those who say only one bridge is needed are wrong. At least for 4890's, 5850's and 5870's I found they are needed. I have read on AMD's site to use both bridges as well.

 

[cadaveca]

I've been saying the same for ages...but...oh well. I specifically tested single vs dual with each set of cards, so when you(Jflynn0) described behavior...well...

 

[brandonwh64]

It has same temps from 10.1 to 10.7 so i dunno? unless there is a beta bios that raises temps which i dont really wanna use LOL

 

[Jflynn0]

this is my first crossfire set up so new to this multi card thing. If they were not going to work was going to sell and get a 5970. I'm still thinking about getting one anyways and selling the two cards since i found a 5970 for a good price
