Hello guys,
I m having problems with my crossfire system. I have a dual Radeon HD 4850 in crossfire.
I keep getting a very poor performance between 15-22 fps in any game. It scored only 9k on 3DMark06 performed 17-42 on the video card tests and 1-2 fps on the processor test.
I called AMD, MSI, Visiontek talked to their technicians, what happens is that each one of them gave me a distinct solution.
The first guy on Visiontek told me that I need 2 HIS bridge connectors instead of only one that I have on atm. A guy from MSI, he said it should be my processor is a bottle-necking to my card performance. The ATI - AMD dude told me that the processor has nothing to do with it, he blames my PSU. What you guys think is the problem below is my system info:
Motherboard MSI 790XT-G45 CrossfireX Ready
Currently Installed Memory: 4GB
Dual Channel Support: Yes
CPU: AMD Phenom(tm) 8400 Triple-Core Processor Model 2, Stepping 2
CPU Speed: 2100 MHz
PSU 450 Watts
2 HD Radeon 4850 512
The AMD tech guy told me to buy any corsair 680w-700w minimum he said the 450 is not enough to power even one 4850.
I do believe that my power supply is really weak to my system but will it affect my video-cards performance. I read on some forums that the power supply will died soon but has nothing to do with performance.
On AMD website the recommended wattage for a 4850 crossfire is 550w only.
*** "PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard
450 Watt or greater power supply with 75 Watt 6-pin PCI Express® power connector recommended (550 Watt and two 6-pin connectors for ATI CrossFireX™ technology in dual mode) "
So, what you guys think about it, what should I get first a new PSU or a processor? Both?
Thank You for replying this post.
