new 3870 Crossfire Setup; Not much faster?

[keninishna]

Is it possible both slots aren't running at 16x? try to update the bios. Reinstall 3dmark and use drivercleaner and reinstall drivers.

Asus M2R32-MVP Mobo 16x/16x

It's in the sig

Edit: Tsk Tsk keninishna, you asked what mobo, then edited your post.

Definitely take the recommendation to fix your driver isssues. Also, check to make sure that your bridge setup is correct. It is very obvious that your CPU is not bottlenecking your score to what would be substandard for most people when just running one 3870. So, let us know what hapenned with that...

8485 non-crossfired, 4x AA, Anisotropic Filtering.

bench it with AA off and AF off in your ati control panel...also turn texture quality to high performance as well in ati control panel...and in 3dmark06 set everything to default 1280x1024 settings...if you are running all these tests with AA on and AF on thats why your scores are lower...for high scores we turn everything to peformance...

single 3870, all settings on performance in ATI (was on the previous run as well), default 3dm06 settings

9919

So 500 more pts for another card in crossfire

Just to show something, can you redo the rest at 0.1 ghz less? This will rpove its not the CPU. Also... you've reinstalled the OS, right?

 

[Boosted98gsx]

This is on a non-refreshed OS. I have already uninstalled the display drivers and CCC. But if I get the same score after ccleaner and reinstalling, then I will declock the CPU and run another test.

 

[Boosted98gsx]

Alright, after driver refresh and Cclean, 10635 This is with crossfire "enabled" all performance settings, and all default 3dmark06 settings.

And finally, system with stock CPU clock, Crossfire, and all ati settings on performance with default 3dmark06 settings.

1 k is a severe difference for only 200 mhz... this could be the limiting factor. I'd welcome a second opinion though.

 

[Boosted98gsx]

.25 ghz across 4 cores..... About 1 ghz total in overclock



2.2 to 2.45

This shows a system with a 3850 getting slightly less than you. Looks like crossfire either isn't on, or your CPU is extremely limiting. Look at the difference in speed too. Nothing as severe as 1k...

at this point I'd have to recommend reinstalling Windows. This will elininate drivers/OS from the list of possible problems.

I think its your cpu, oc that thing higher.

 

[jokers_greg]

Think I should OC the Phenom 9500 some more then?

I don't know whats wrong tbh, but its not your cpu. Sure the Phenom isn't great but it would not bottleneck your cards that much. You should get at the least 16k in 3dM06

I don't know whats wrong tbh, but its not your cpu. Sure the Phenom isn't great but it would not bottleneck your cards that much. You should get at the least 15k in 3dM06

But look at that massive difference with only 200 mhz. Thats something that isn't reflected in the reviews.

I am switching over to 64bit vista ultimate

I am switching over to 64bit vista ultimate

Let us know if it works better!

 

[jhanby]

Just to add my opinion here as well, My rig gets about 10k in '06 with a dual core and a overclocked 3850. Defiantly a driver problem

 

[Boosted98gsx]

Okay, just upgraded to Vista Ultimate 64 bit and here are the results on a BRAND NEW benchmark
