taking full benefit of 5850 crossfire - what is radeon pro

post #1 of 12
Thread Starter 
hello.
I have 2 sapphire 5850 cards on a p45 system in my sig, and my cpu is at 4.2ghz but as you guess cards are suffering. I play BC2 alot and my reason of crossfire was mostly for that game. but fps didnt changed. I was just able to crank up edge detect anti alias and other stuff, but still 40fps.. I never been able to see what crossfire is actually.. some people say this driver, that program. i didnt even had those issues bcuz of my aged cpu.

I read a program called "radeon pro". what is that? and how it works? what should I know-do for a better crossfire performance? which is better 5xxx driver?? which driver should I use**??. what are the must have little programmes-utilities for cfx setup??

monday i will be getting a new p67 mobo with 4gb ram and 2500k cpu. will a stock sandy bridge 2500k be enough to fully utilize GPU's? if I have to overclock the cpu, how much is needed? asking this cuz i wont be getting a new cooler. I will be using my sunbeam heatsink with a new adapter: cheap solution.

My resolution is 1080p. single monitor.

since I upgrade from a very old and bottlenecking dual core cpu i just want to put those 5850's on fire
thx

A stock 2500 shouldn't bottleneck you.

I, too, just learned about Radeon Pro, so I can't help much there.


All you need to do is install the latest drivers from AMD and the latest CAP. You can find that here.

Hope you get it working.

Radeon Pro are just some custom profiles for specific games which are meant to improve the game visuals/fps in one way or another. You can read what each profile does on the AMD website.

I don't know what you mean with your last post. A stock 2500k and two stock 5850's will max out 100% of the games currently on the market, badly optimized games not included.

A low end dual core like the Core 2 series severely bottlenecks Bad Company 2. 2500 won't bottleneck at stock. get that.

@ Inter Stella:

HECK! One 5850 will run Bad Company 2 at around 60-100 FPS. Your CPU is the problem. It is bottlenecking it like there's no tomorrow.

I remember that I used my HD 5850 on a Phenom 940 Quad Core.. (NOTE not Phenom II) and I only got like 40 - 60 FPS. Then I used it on a Phenom II 1055t and it ran at like 60-110 frames.

@age_ruler1
all I wanted to know was if I need to overclock the cpu to 4.5, it will be impossible with my current fan. If cpu gonna bottleneck those cards on crossfire, then I should grab a new cooler.. I justed wanted to ask it and get an answer. cuz im really not planning to overclock..and already buy an adapter for my old sunbeam cooler.

@Sonolegolas
thanks for answer
lots of sb rigs building for overclock to 5gigahertz. Only thing I want is smooth >60fps. thats all. I believe I suffered enough on my e5200 old-crap cpu my question was how much FPS gain this system will get when you overclock 3.3stock sb to lets say 4.7ghz? you say single 5850 is capable of at least 60fps. well let me tell you: last time I played with my e5200 @ 4.1ghz, 5850's at crossfire, I get 40-50fps in 32player match.

should I expect THAT kind of performance from 2500k, if what you guys telling me is true I AM HAPPY ITS GREAT!!!
i will build it on monday.. motherboard probably still tripping in ups truck cuz its weekend..lets hope things will be smootth and nice.

I will post my results for people like me too see and compare too.

A 2500k at stock speeds is absolutely beyond me. Why? Just WHY?!

Spend $40 and get an H50 at least at your local best buy. ^_^

You not only have a cpu bottleneck, but a mobo bottleneck as well.

You'll see a 100% improvement moving to a sb system, you will double everything, min/max/avg fps.
