|
 |
Hey guys,
Just got myself 3d club's 4870 and can't make it work. I can see the POST screen, but if I try entering the bios or just continue to windows, the screen stays black. I connected the card just fine, with both 6pin power connectors. I have a 530w TAGAN PSU with 30 combined ampers on 12+. I was confident it would be enough.
I returned my old 7900gs and everything worked like a charm. Tried 4870 again and same problem. Also, 3 red lights at the back of the card flash on boot but do turn off so I suppose it's okay. What I don't understand is why it shows the POST screen but fails BIOS? It's text all the same, if it has power for one should have enough for the other.
I don't have another computer to try the card on...so I need advice as to what might be the problem. Maybe the card is faulty?
Rest of my specs:
C2D 6300
2 gig ram
Asus p5b mobo
1 hdd
Thanks in advance.

530w should be ok...I have a 4870x2 and the spec says min 650w, although I have a 850w PSU. Cant really think of anything else it could be at the mo. As you can see the post screen, its not something simple as the cable not being plugged in properly or somet.
But hang on, you say it wont start BIOS?...You mean no matter what you do it goes right in to loading Windows?.
If you don't have a lot of stuff that you need, a reinstall of XP/VISTA might do the trick (thinking extreme here) Although it might be something completely different. But why would a new gracard create such an error?.

3 red lights = not enough Power iirc.
I also think fisk should be unbanned.

anyway you could borrow someones +650watt psu ? its not so much the wattage but quality of the parts giving a stable voltage when your hardware pulls alot of wattage

A big wtf happened.
I exchanged the card for the same one just brand new thinking it might be faulty.
First thing I plug it in everything works and I'm happy. Then, bam, same crap again.
So I keep connecting and disconnecting things until suddenly it works again. Then stops again.
I really tried to single out a certain component that was to blame, from case fans to dvd, hdd, sound card...no luck. Looks random. In the end, I took the audigy 2 out and it is working since then.
I have no idea what is the problem.
Oh, and I am disappointed with 3d mark 06 score. With my 6300 and 4870 I get ~8800. Big wtf here. I hope that later when I'll reinstall the OS it might improve.

Well, I did uninstall the Nvidia drivers and then used Driver cleaner in safe mode. God knows if something is still there. CCC isn't working though.

You should have cleaned old drivers with uninstaller pro, it moves all your files in registry... And if I'm not mistaken you need to have all of the NetFrameworks installed in order to have a working CCC...

if your windows is a few months old , it doesnt hurt to reinstall , with all the updates and new drivers.
That way you can excluse any software related issues
