i have purchased an hd 4870 x2 graphic card, it and all the computer powers off as soon as i go to bios main menu
it is not a heat issue so i'm thinking it's either the power supply or the motherboard
my board workes 100% fine with nvidia 8800 gt but not with the ati; it also takes vert long to go to the bios
my motherboard is an asus p5ne sli
my power supply is an easy cool 700 w
it's voltage are as follows :
+3 3dc = 36a, + 5vdc = 40a, +12v 2dc = 20a
-12vdc 0.aa +5vsb = 3.0a
the graphic card needs 40amp
is my psu enough? or should i change my motherboad with an intel cheapset
1 more thing; my bios with the nvidia card is latest
when i put ati card it goes to original, i couldnt upgrade it because it will shut down before i do anything
i do get motherboard logo on startup all the time with ati
well your powersupply gives 24amps on the 12v! i cant beleive its running your cards
actualy i am only running one card called "hd4870x2) not two seperate cards, and
aparantly it needs 40amps on the 12v rail.
but in your case you should need even more! unless i am wrong
Its running fine actually. I don't have any power issues. I'm running Crysis with max settings and everything is going well. I'm getting a huge boot in speed compared to the previous card.
I just spent the past day pushing it as hard as I could to see if there would be any problems. Still stable and no sign that there is any inefficiencies.
ok i got a 850w 35ams power supply and its no longer switching off, the problem now its V slow, even to go to the bios
it takes 5min and to load OS takes 10 minutes i know it needs bios upgrade but the mobo wont allow me, i think anything
not intel chiped wont work well with ATi
if you have the HD4870x2 2gb Graphic card, what is your model number for the mobo so i can buy same as yours?
cheers...or can you recommend any that your friends are using and not having huge problems with.
