Hello, I have a laptop with Radeon 7500. I've had the laptop a couple of years and it has has decent enough spec. I'm a graphic designer and suddenly yesterday i noticed my laptop LCD screen is displaying gif and Jpeg images as if there are bits missing out of them. I've tried all my different graphic software and they display the same. However all my icons on the desktop for example are still perfect. As far as i know i have changed nothing with the laptop. Anyone know what this may be? Dean M

I currently have 256 DDR 133mhz of memory. I would like to double that by buying another 256. But i can only find 256 DDR 256mhz. Does anybody know if this will work with my 133mhz existing memory? I can't seem to find out from anybody if you can mix the MHZ about? Thanks in advance, Dean

Okay that was a dumb question i guess up there on my last post! Of course they will work to together i guess, i mean they're identical apart from one is 'DDR-SDRAM' and the other is 'DDR-RAM'. What is the difference anyway? Dean

Found out with the CPU-Z Freeware utility that i have 'DDR-SDRAM' Can someone please let me know if 'SODIMM DDR-RAM' will work along with the 'DDR-SDRAM'??????????????????? Dean

Christianb: I did have a look at crucial thanks. And it has helped me a lot to understand a couple of things. I would ditch my 256 and just get 512, but the 512 is more than double in price than the 256!!! That is so weied isn't it? Just like you mentioned though that it sometimes is like that. I guess i could just buy 2x256 though. jdemitro: My memory module definitly says on it '256 DDR 133mhz'. So i don't know whats going on there. And like you said > You've never heard of DDR being 133mhz, so i guess thats why everyone is possibly confused in shops when i show them it! Thanks for all you help everyone! Dean

The following link is the existing memory that i have now, accept mine is 133mhz http://partsurfer.hp.com/cgi-bin/spi/showphoto?partnumber=285272-001 And this next link is what i wanted to upgrade to. http://inet.se/produkter_info.asp?p=5302510 Do you think they will be compatible what any hassles?

Sampson: So what you mean is instead of buying an extra 256megs, buy 512 megs and ditch my existing 256megs? And i suppose, just out of interested, would it hurt to then try the 512 with my existing 256? If it doesn't work then i've got nothing to lose have i, i'll just then remove the 256 and continue with my new 512. Oh yeah, does something happen on screen when i boot up after theres extra memory been installed? And if i try mixing them like i mentioned just now, they won't blow my laptop up will they if it doesn't like the two different MHZ???!!! Thanks a million, Dean

Oh, well i don't mind that. As long as they both work together, its still going to be a hell of a lot faster then i have now. Don't want to hold you to anything, but do you reckon then as long as the memory chip is compatible, it will run along with my different MHZ? Thanks for your help, Dean
