1) What kind of work are you doing: Programming, graphics design, video editing, or something else that requires memory and processing power?
2) Is that Vista 64-bit or 32-bit? I'd suggest considering 64 bit before trying to go down the more memory route as 4 GB is the limit of 32 bit without resorting to tricks.
3) My guess would be that the Dell likely doesn't handle more than 4 GB of RAM though unless you are sure that the RAM is the memory issue and not something else, e.g. buggy software, video memory issues, then it may be that you'll fix the wrong thing.
I have a new system from dell. Thing runs great....however I use it for work and it's constantly being pushed to the limit. I'm getting some memory erros once and awhile and of course it happens while i'm working on company time and it needs to be fixed.
Dell Inspiron 530
Vista Home Premium
Quad 2.4 processor
4gb 677mhz memory(only 3.25 shows)
250gb primary drive
500gb secondary drive
256mb ati 2600 xt graphics card
I think I need more memory....probably more along the lines of 6-8gb. Does anyone know if this Inspiron 530 can even handle anymore than 4gb? If so ... which Vista product must I get to allow more than 3.25gb of memory use? Vista Ultimate?
