My motherboard is IntelD845PESV. i use 512 mb DDR 1 RAm & 64 mb Nvidia Geforce 2 Mx/Mx 400 AGP card. Now, i want to upgrate the AGP and RAM . In the intel site maximum RAM supported by this motherboard is 2 mb DDR 1. but no clear indication about the highest AGP card. Please tell me what is the best geforce card compatible to this motherboard.

Hello
I dont think there are any agp to pci ex riser cards.As pci e x16 is part of the motherboard circutry.

There are pci to agp riser cards.If your going to be playing some of the latest games.Most games in the past 3 yrs require a pci x16 vid card.

I suggest geting another motherboard,chipset,and memory.Along with a Pci e x 16 card min 512mb.

nvidia 9600gt agp version 512kb vram.

if you get a card with 1gig of ram on it, you would have to have at least thqat much, 1gig, installed into your system ram as well.

You did not list the card specs (AMD/Nvidia model) for reference. If you don't have a card currently get the best AGP 8x card you can find. Keep in mind that that with that CPU a higher end card will probably bottleneck so don't go crazy. Some web consensus is a geforce 5500. Possibly a Radeon 7000 series for higher frames.

My friend you can add RAM on your VGA by purchasing another Higher Video card  RAM. you can buy 512mb (265 - 512 bit) VGA Card to increase your VGA RAM. 

ya.you can use a Geforce Nvidia card to your system

hi..if u want to run as good that VGA u need to set in the Bios as init fist display as AGP then find what AGP size appear on bios..if this all OK try to booting the system..thanks and Good Luck..^_^

this will make most 3d stuff work better

The motherboard you mentioned supports DDR1 RAM.

For windows xp and general application 512 MB is enough.
But if you use memory intensive applications like image/video editing then you can opt for 1-2 GB RAM.

This motherboard only support DDR type of RAM up to 4GIG , 400 MHz • 333 MHz this are the support speed of DDR RAM, so you can go ahead upgrade up to 4 GIG of RAM and that will make your computer very fast...

This motherboard has an 8x AGP slot. So any 8X AGP graphic cards will suit this mobo. As your local reseller for any 8x AGP based graphic cards from ATI or Nvidia.
