I just bought an ASUS HD5770 and it's installed and working with latest catalyst, but I get some really low ratings on 3dmark06 and low frame rate on Modern Warfare 2 (multiplayer mainly, when playing with everything on top at 1440x900 the game gets really choppy). I'm getting almost the same performance I used to have with my old 8800GT.
I thought I could play MoW2 at maximum settings with that video card, so I guess the rest of my computer has something to do... My motherboard, Ram and processor are quite old, so, can that be the reason? I can't get all my Hd5770 to work with my pc?
My specs are:
Asus Striker Extreme with nForce 680i (Bios revision 1004, from 03/05/2007)
Intel Core 2 Duo E4300 @1.80 GHz
2GB DDR 2 Corsair (2 modules on dual channel)
Asus HD 5770 1GB on PCI-Express x16
600W Nox Urano
I can post some pictures of CPUZ, GPUZ and 3DMark 06 if you need them. I have been thinking about updating the motherboard bios, but I'm not sure if it would really improve anything.
Also, It worries me specially becouse since I installed the new HD5770 the systems takes around a minute to get to the first "bip" and the bios screen. With my old graphic card it only took a few seconds, so I was wondering if there's something wrong with the graphic card.
A "rail" is a "Cord" from the PSU?. I mean, right now I have the following things plugged:
-One cord that goes to the motherboard (the big one )
-One cord that has 2 small ends plugged on the motherboard.
-One cord with 2 fans plugged
-One cord with the DVDRom and the floppy
-One cord with only the video card
Is it ok??
Also, when I OC it a bit a get better results on 3dmark06 (more then 1k points more when OC 15%), but, although 3dmark works fine I get reboots and freeze when playing.
The only things that really worries me now is that the pc takes around 1 minute from turned on to bios post. Meanwhile it tries to read from the dvd several times. This started happened when I changed the Video card. May the video card bios be wrong? I tried unpluging everything but the MB and the video card and still takes around a minute.
