AGP compatibility?

by CaptainArcher / July 11, 2005 3:33 PM PDT

Still newly registered with CNET, but have been reading reviews on the site for almost 8 years. My question is simple. I have an HP system thats about 3 years old. It originally came with a 16MB agp graphics card, that i soon after upgraded to a 64MB card with s video output. I am now thinking of upgrading one more, to a 256MB card with dvi output. I want to know if the agp 8x card will work on a machine this old? is my agp slot not fast enough (its likely 2x, the first type of agp). not too sure on this one.... or should i just save my money and put it towards building my own system from the groud up? Thanks in advance

Even if it does work, which is unlikely. Your PSU won't be able to handle.

however it depends on several factors. Please give the model number and other info so maybe we can check your PC out..re the the notice in red about providing info on your PC when you posted.

My best of the three computers I have is 3 years old, still upgradable, and will play any game out there, except I may need to upgrade to a GeForce 6600GT AGP video card to play Battlefield 2.

hp pavillion 7865

with an amd athlon 1.2 ghz processor and upgraded to 512MB of pc133 sdram. i have recently replaced the power supply with a 350 watt, so that would not be an issue with a new graphics card. the only real question i have here is if there is any reason an agp 8x card would not work on an older agp slot. im not sure where to find info on exactly which motherboard and chipset i have as i explained in a different post, i cant access any bios info at startup

Checking HP's site on your 7865 did not reveal what AGP x speed of your motherboard. You need to find out if your motherboard is 2x or 1x. If so you cannot put a 8x card in because of the voltage differences. You can put a 4x card in a 2x or 1x. I have a 4x card in one of my 1x computers. If you have a 4x slot, to be safe... make sure the new card indicates 8x & 4x, even tho generally the 8x cards do have the correct voltage for 4x & 8x.
Sorry I can't be of further help.

Try running Belarc Advisor, that should tell you what motherboard and chipset you have.

(NT) (NT) Does an AGP 8x card work on a 4x Motherboard

Yes, a

4x motherboard supports 1.5v. The 8x video cards are .8v but almost all are designed to also support 1.5v and can be used in 4x motherboards (OEM's of 8x Cards didn't want to lose out on selling to millions of 4x computer owners). An 8x video card will not work in a 2x or 1x motherboard. I would like to be safe with some of these fly-by-night 8x Cards by being able to read on the box/or discription...8x/4x.

Keep in mind that an 8x Video Card in a 4x Motherboard will perform at the 4x speed. Really, an ordinarry person would not be able to tell the difference in performance between the 4x & 8x card.

Im reasonably certain that I have either a 1x or 2x agp slot, because agp was very very new at the time this pc was purchased. at any rate, Ive decided to stop sinking money into this machine and build a new one or possibly buy a media center as i have seen some great deals advertised lately. maybe i should just do both....

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
