help with 2x4890 and 3dmark
 

Basically I am just wondering why my scores are so terrible. I'm a total NOOB to 3d benching and I'm runnning 3dmark05 with a 1090T @ 4.25GHz and 2x4890 @ 1000/1100....I'm getting 30000 points with 1 card and 31000 with 2 cards which seems really low. I know both cards are working simultaneously at least according to afterburner. One thing I have always noticed and thought was really stupid is that when in crossfire neither card works nearly up to it's full potential. They stay under ~35-40% load.

I'm wondering if something seems rotten or can I actually expect to gain several thousand points by increasing the CPU 2000MHz? I've never 3d benched at all really and I am trying to get things figured out before I start pouring LN2. I've seen some pretty good results with say a 965BE(quad) @ 6.2GHz so I'm figuring my 1090T(heka) @ 6GHz should be either very close to the same or maybe a bit better in the multi-threaded ones.

Thanks for taking the time to read.

05 is very CPU limited. What drivers are you using?

cat 10.12.......... by cpu limited you mean cpu dependent and cpu speed will make a huge difference?

on amd idk nothing but doesnt seem the best in 3d unless clocked up there but im going to cf 4870&4850 see what i get :)

Cool.....let me know.

well ran it the e8500 not the best for 06 :P

but ran 4850 900/1150 got 14k 4870 800/1050 got 15k in CF 20k

but load on both where in the 90+%

Check gpuz to see if the pcie is dropping lanes on the second or first card.

EDIT: thanks for taking the time to test that DOM:thumbsup:
Always, forever, in every computer and no matter what 2 x 4890 I'm using when I run CFX both cards only run ~ 40% tops except an occasional spike. Usually each card is at a fairly steady 30%....which never made any sense to me. Each card alone runs ~90% or whatever it needs. I verified that the core clocks are coming up from 240 to 1000 when 3d starts.

Dropping to like 4x or something you mean? Pretty sure it's not and it is a newer board(CHIV).

Please help me I'm stumped
 

I just ran 3dmark 03 a couple times and I get 42000 less points than this guy with a very similar setup. How can this be?

I had my system in diag mode with afterburner going to verify that both cards are staying clocked up and they are.

I'm stumped and I have to get it figured out before I start pouring the last 20 liters I have, hopefully before it all evaporates.

Look at these 2 screenshots........:Dizzy: I should theoretically definitely be able to beat 109000 points. What's the deal?

EDIT: btw my cards were @ 998/1097...could it be that a 965BE is just flat out 40000 points better than a 1090T in 03...I better go eat lunch and try the 965BE although I'm sure that's not the problem.

It sounds and looks like Crossfire isnt working for you. Must be something wrong with either your drivers or your OS. What kind of score do you get when Crossfire is disabled? I doubt very much its cpu. 03 really isnt all that dependent on cpu. What are your CCC settings? everything set to performance mode and enabled triple buffering?
