upgrading video ram

epuchi20 · Oct 14, 2005, 12:53 PM

HI, I have an Acer Aspire 1603 with 512DDR and Mobility 9000 with 64ram. I have read in some topics that I can increase the ram for the videocard if I go to the BIOS in restart and search for something called "UMA". Some people said that I can put it in 128ram (but it's not very logic if my Ati is 64ram?? I dont understand

). So I went to the BIOS and searched for the "UMA" and I cannot find it!! Maybe its related with Shared memory?? Or Dedicated??

Please Can anybody explain me this?? I dont know if my Ati is shared or dedicated.

THANKS A LOT!!

P.S.: I'm using Omegadrivers 2671

UMA stands for unified memory architecture... its how laptops and notebooks work

They share the ram between the system and the video card,

UMA. ALSO known as shared memory, is how you set how much you wish to allow the video chip to use

so can I modify the amount of ram?? can I put It in 128videoram? where I have to go to change it? Because I go to the BIOS after reboot and I dont see any place to change it.

Thanks for replying!

The purpose of that is that I want to put a new 512mb module of DDR (now I have 2*256, and After will be 512+256) to play games better, so if I can change the videoram and put 128mb It would be a better machine

should be in either the advanced settings of performace settings

also i wouldn't advise mixing ram module sizes as it can cause system instability

I have search in BIOS menu and I cannot see the UMA settings, please can you be more exact where can I modify it?

All the laptops can modify this "UMA"?

Otherwise I have another PC, AMD desktop with 512+256DDR and I never had a problem of incompatibility.
Does anyone know if It will be diferent if I have 1GB ram (so putting 512+512 new ones)? I'm talking about running games, not increasing the speed of windows starting.

THX 4 all !!!

My bios is a PHOENYX, I dont know if it matters.

I have read in in another post that may be I can change the UMA settings if I install the ORIGINAL ACER DRIVERS, then I change this and Then reinstall the Omegas ('cause some people say that with the omegas you cannot change it on windows).

No its the bios settings. But remember when you dedicate 128 mb of ram, that means 128 mb less for the rest of your applications, its shared ram, not dedicated.

epuchi20 · Oct 23, 2005, 08:23 PM

ok, but the question is that where can I change the UMA settings?!?! I have a PHOENIX bios and I cannot find the place to change it!! there isn't a place in the bios menu to change it!!!. PLEASE if there's anyone that has a Phoenix Bios please answer only that question. THANKS !!!

If its not in the bios you can't change it. Phoenix bios don't allow you to change very much, there really isn't anything you can do unless you're manufacturer decides to use a different bios which is unlikely. Phoenix sucks, I have them too and hate it.
