I have a Compaq Evo W6000 with a gig of ram. Can I upgrade it to 4gigs or is that two much and I have to settle for two gigs?
i think now adays, you can put up to 8 gigs of ram on a pc if it supports it...usually you can double what the factory supplied you with...2 gigs of ram works for me...now for you, it depends on what you do with the machine...if you are a gamer 2+ gigs, if you just want a fast pc 2 gigs is ok.
your only limited by how much the motherboard can handle...most cases thats four gigs if you don't play games...1 gig is enough...if you do play, you'll need at least two gigs anymore than that is really over kill unless your doing high end graphic design... (you can get away using 2gigs for gaming as long as you have a decent video card to back that up)
you can only go up to 2gigs. but it's rdram, which is way more expensive than regular ddr2. the w6000 is a workstation system. not sure how you got one of those, but they are meant for 3d work.
workstations are mostly used in businesses, because they are expensive to buy, maintain, and upgrade. rdram is hard to find; internet is the best bet. you'll be paying top dollar for a 2gig set. probably around $300+. specs for compaq evo w6000
With the price of RDRAM, you should stick with the 1GB that you currently have. Of course, if you're set on upgrading you can purchase the memory here. http://www.cheapestrdram.com/p102/2GB-(4x512)-PC800-45-RDRAM/product_info.html You can probably find it cheaper somewhere else, but unless you buy it used, it's going to cost quite a bit. By the way, I'm assuming that you have four 256MB chips, if you currently have two 512MB chips, then you would only need to buy 2 more 512MB chips.
go to crucical.com and down the memory program its a small file and it will tell you whats the max you can run
If it's windows xp 1gb is good enough. I use run my windows xp pro with 512mb ram with no problem even when playing games and doing video editing. I would just keep what you have right now, when I upgraded to 1gb, I couldn't tell any difference. If it improved performance it was so small that it's unnoticeable.
