Major problem with the 4850!!!

I orderd 2 4850s for myself and my brother. My friend Bob also got one. We just recieved them and are having major problems. First off my videocard hoggs 3gb of ram. I know this cause when I install my old x800 it doesnt. Not only that but my CPU usage goes from 0% for the x800 card to 30% with the 4850. Games arnt even playable. My brother's computer has a gigabyte mobo but still has the memory problem yet his CPU stays at 0% usage. I have an Abit mobo so I know its the cards. The cards are by Asus.


Ive done a fresh reformat with no luck. Im running 64bit vista but my frined Bob is using 32bit vista and still has the same proble.


Why does everybody else on newegg say the card is perfect when im having so many issues?

That makes no sense, the video card would have no effect on your system RAM.

You guys are probably doing something very wrong. What PSU are you using? Did you install the latest drivers? Does your case have decent airflow?

Do you have the 6pin power connector pluged into the power supply?

Are you going to try to run 2X 4850 with a 500watt power supply or just one. That is not clear.

And your Bro, 400watt prob. is not enough for a single 4850

quote:
450 Watt or greater power supply with 75 Watt 6-pin PCI Express power connector recommended.

Yes i do have a 6 pin power connector to my video card. The PSU actually comes with two 6 pin power connectors.

My friend Bob just message me saying its cause of superfetch and that vista is made to use all your ram as a cache but that doesnt explain why when i use a x800gt card my computer only uses 700mg of ram.

Did you remember to install the motherboard chipset drivers with your fresh install of Vista?

Installing the altest GPU drivers are one thing, but the card won't work right at all without the proper/latest chipset drivers.

Did you remove all the old Video Card drivers before installing new drivers? @Control Panel

and use something like, Nasty File Remover ( Google, its a free download)
before installing new drivers

That's weird. I have Windows Vista (with superfetch on to my knowledge) and it chows down only 300-400MB of ram with an Asus 4850. Very odd.

When you install a fresh copy of Vista, it takes a while for the OS to "calm down". Let it do what it needs to do and after a couple of days you should notice the OS behaving a little better.

Keep in mind that your video card does not use computer memory. It has it's own memory. Unless there is a driver bug, it's just a fluke in my opinion.

I installed a 4850 yesterday and I'm running Vista 32bit. I haven't noticed anything strange yet. I did not reinstall Vista. I'm also using the Catalyst 8.6 Hotfix drivers. The card works well.

Im not the sharpest marble on the block but I have learned to remove the Nvidia, Ati drivers from "add and remove programs" ,Reboot and use a tool like Nasty file Remover,( check it out, it still finds files after removal). Then install the new drivers.

Ok, glad to hear problem fixed!

vista... i just threw up a bit in my mouth @.@

It might not be related to the new video card at all. Maybe sense it's a new install of vista it is re indexing everything, which could explain the cpu usage. Try turning indexing off and see if it makes a difference

Okay i verified that the card works in xp 32bit and xp 64bit ( i get 0% cpu usage) and now im really lost.....is this problem software or hardware?

Yes I have tried it with SP1 and still get the CPU usage problem. It is not updating windows and superfetch and indexing are disabled. I have a e8400 thats 3ghz and the gpu makes it use 30% of it but only one of the cores so its actually at 85% but the other core is at 0%.

I have had the 4850 in so long and tried so many troubleshooting steps that when i pluged the old 6600gt (nvidia) or the x800gt(ati) card the processor is still at 30% usage. This is good now im getting somewhere. This means that the problem is its software and it has something to do with vista installing a faulty driver for my unique configuration.

Are games still unplayable? CPU usage itself isn't necessarily bad...

If it is using 30% all the time, have you check to see which process is using the cpu?
***EDIT*** 4min late on response. Glad you fix the problem.

Chipset drivers dont fix the problem. There are no processes that are using the CPU.

I need an alternate driver for ACPI for vista.
