Onboard Video

Does anyone know how to increase the memory on an intel 82845g
chipset? I looked in the bios and it only gave me a choice of 1mb or
8mb. When I looked at intel's site it said this chipset uses "dvmt" or
something like that. Any helpful suggestion would be appreciated.

get a new video card?

"On board video"

Sorry mate, but on board video went dead after the days of Quake. Sounds like you need a good video card! :smile:

Oh God. I sense another NVidia v ATI thread coming on.

i'm yawning in anticipation already :razz:

onboard video sucks, i got fobbed off with it once on a motherboard on a prebuild. needless to say i arranged alternatives ASAP.

Option one, if you do have an agp slot, then get an agp graphics card.

Option two, if you don't have an agp slot, then get a new mobo and graphics card, agp graphics cards are way faster than pci, and offer better upgradability.

Leave it there, no suggestions for video cards.. But a basic rule of thumb, onboard anything will blow bad for games.

Edit:/ Just noticed you said tweak, you cant tweak out what you got as far as onboard video, but there is this: http://www.tweaktown.com/document.php?dType=review&dId=324 use this to tweak out windows XP to make you computer run even better than it did before.... and it works, no BS.

Thats true enough to a certain extent but not all onboard graphics are crap - one of my PC's is a XP2500 @1833 mhz with onboard Gforce 4MX graphics @300mhz, this will break 10k in Aquamark3, in UT03 benchmark @800x600 it hits 83fps in the Flyby and 55fps in Botmatch. Its ran almost every game ok @800x600, its ironic that i've had more problems running games on a 9800pro :sad:

From the Intel info - dvmt is a graphics driver that dynamically allocates video memory, it'll allocate up to 64mb of system memory for graphics if theres enough system ram to do this. The 8mb is static and used for legacy stuff, it may be a bad thing to max it out as XP can't use this ram for video.

Its been a while since i tweaked a PC with Extreme graphics so some of this next info may be incorrect or not help much.

Under Display Properties there'll prolly be an option to set the amount of Direct3d texture memory, try setting it to 32mb and work up from there. Set any texture/image quality setting to low.

Some games may not work with texture quality set to high, set them to low and use a lower resolution.

Under System Settings there may be a driver setting which configures the amount of ram to allocate to the video, if you're unsure of what you're doing then don't mess with this.

The video uses system ram so tweaking the BIOS memory timings, CAS latency etc. should improve the graphics performance.

These things are usually trial and error until you hit the systems sweet spot, best of luck tweaking it :smile:
