no no you dont have to get the same make, however i would stick to the same size if i were you. A 256mb ram should cost too much at all. Or you could get 2 X 512mb, that'll give you a juicy amount of ram.
The makes of you ram determine it quality, there are some very good quality makes such as cosair, crucial, kingston etc... These perform faster than there cheaper counter parts. But for a low end user who is not over clocking i thing any make will be fine
One more question, if I bought two new sticks and took the one I have at the moment out, would all my files and stuff be gone along with it? Oh yeah, does what MHz it is matter?
oh, your getting a bit confused as to what ram is. Ram is not were you files are stored. these are stored on your hard drive. You ram is a kind of working short term memory. It is cleared every time you shutdown. In simple terms information is taken from your hard drive and a copy is stored in your ram, which is were it will sit and wait to be passed to the processor. Some data will sit in your ram for as long as your computer is turned on. But it will ALL be wiped the second you restart. So in short there will be no damage to your files what so ever when you change or remove ram
As for MHz, i cant answer directly as this depends of your system. Best thing to do is get some ram that is of the same speed as you current ram. To determine this i recommenc using cpu-z (you will se lot s of people recommend this) it can be found here: http://www.cpuid.org/download/cpu-z-128.zip
load this and flick to the section that says memory, then look at the line that says "frequency" this tells your the MHz of you current ram. You cant really go wrong with using the same speed (Mhz). You could buy faster of course, but without knowing too much more about you computer i wouldn't be able to tell if you would see any benifit
oh just read the rest of you post, the PC---- is a system used to determine the speed of you ram (i recommend reading ram 101 which is posted at the top of the ram forum)
ahh, this is were the marketing language as caught you. You are buying ddr ram, which mean double data rate ram, which means that i can transmit data at both the peak and trough of a cycle, so twice in one cycle, so thereby turning a 200mhz into a 400mhz, confused yet? So a 400mhx will actually run at a 200mhz clock speed. Incidently a ram module that runs at 400mhz can be descrided as DDR400 or PC3200. And will just slot into you machine like a glove. But do follow some instuctions, and be sure to earth your body before touching ANY components
That isn't a motherboard but I can tell you your board can't possibly support DDR2, AMD doesn't support it yet (they supposedly are adding support in 2006)
Uhh....That isn't a motherboard but I can tell you your board can't possibly support DDR2, AMD doesn't support it yet (they supposedly are adding support in 2006)
On page 5 of the manual it says that your board is rated for up to 2GB (meaning 1GB per slot max). The speed depends on whether you have the K7S41 or the K7S41GX
So essentially 184pin DDR SDRAM 1GB sticks is your max
