This post is from a friend of mine can anybody help?
Hey All
Im only getting a score of 9727 3DMark05
Was wondering if the Power supply would play part in it?
Heres a run down on the hardware
Antec P180 case so there plenty of cooling
AMD 64 3500 Artic Freezer Pro Cooler
DFI CFX 3200 DR
Sapphire X1900XTX
Connect 3D Crossfire editon X1900
Hiper 580 Modular with FSP Booster X3 VGA Power Supply
2GB Kingston 3200
2x 16MB Cache 74GB Raptors raid 0
NEC DVDRW
Audigy 2 ZS
O/S XP 64 Professional
My Friends System had the same Motherboard with AMD 64 X2 4400 with just 1 X1900XTX and got a score of 11,000.
Is it my CPU holding back the score or does anybody think its the Power supply
Cheers Ally

Hi my friend!
Well, it is kinda strange, that you get lower points than your friend with that crossfire.
And Hiper is as far as I know a good brand. And you have sufficient power to be able to run 2 X X1900XTX. But what is that FPS booster stuff? never heard of it before
A slightly unstable psu, would have an inpact on the performance. But if the Hiper is stable I dont think that is the problem. Why not download "Motherboard Monitor 5" and check the rails stability. Also download "Prime 95" Torture test. And let it run for an hour. But monitor the CPU temp closely. Prime heats up the CPU quite much. If the temp, starts to wander over 60 C shut down Prime. Use Prime wile checking the rails in Motherboard M. 5.

That FPS booster? Can you have it on and off by will? Then try Benchmark with and without the booster and see what results that gets? Sometimes such booster stuff makes things worse instead of the oposite.
Also, maybe you should try a tweaked videocard driver?
Go here and register for free. The Xtreme Warcat 6.5 is a good driver. They have 64 bit version of it. (I have checked now).

But unistall your previous driver in control panel + add / remove programs. And use the driver cleaner from the link below, before you install the new driver.

Read the cleaner instructions carefully.
Use multiple cleaning filters and remove all ATI stuff.
Hope this will be of any help for you.

Hey Goranpaa
its ally here on Spartin's loggin, im going to register just thought i would post here rather than have seperate threads for this topic.
1st of all thank you for the quick responce.
I am a regular user of prime95 in work and happy that the cpu and ram are fine.
I agree that its a good diagnostic tool. 
As for the X3 Booster VGA power supply, The reason for it is that the hiper can't supply enough amps on the 12 volt rails to give the cards there full potential. The hipe can only dish out 18A on one rail and 10A on the other. The FSP VGA PSU can dish out 25A on both rails. Im told that Each card need 22A on each card. I have tried it with the Hiper PSU on its own but get a simular score.

I pushed my CPU up to 2400Mhz and put the 580 chipset on strong and have got up to 10,700 mark but still i see ppl getting much higher scores on crossfire than i am getting and ATI says the 2 cards will Score up to 15,000 marks in 3DMark 05, Maybe im just being a little fussy.
Cheers
Ally

O.k my friend.
Now I understand what that booster is about. Nice stuff!
But what I really meant with Prime. Whas that you should run it together with Motherboard monitor 5.
To see if the Hipers 12V rails are stable under stress?
