I suppose that you are talking about memory or aka (RAM).if you have two 512mb sticks of RAM you have one gigabyte of RAM. The more RAM you have the faster your computer will be. So the awnser is RAM or A Gigabyte.
Yes,i have 512mb ram and Ati with 128 mb
Mine came with two banks of PC-133/512MB cards.
I think it is time to buy a new PC with higher RAM.
yes but the game speed will be very slow
1 x 1Gig 2 x 512Mb all PC 3200.
It take half hour to inst
512MB is the suggested minimum amount, and 1GB is the recommended optimal amount.
How old of an PC is it?Likely if it was made in 2001 - 1998 it's max ram ammount is 512 mb. Try taking the 128 out and leaving the 512 stick in there, Make sure that ram is compatible with that PC Likely PC133 in you're case, Good Luck.
The motherboard chipset or memory controller probably doesn't support it.
It may be two slots of 512 installed
512MB equals .5GB or 1/2GB.
No - 512mb is twice as much as 256mb !
