If I bought a stick of 512mb RAM DDR 400, would that work along side 2x 256Mb pc2100 RAM?
thanks

no it wont, they have to be all the same speed.
Yes it will, but they will all run at the speed of the slowest ie DDR266.
If you want to use them together then get a 512MB stick of PC2100 and save yourself some cash.
If you want the 400DDR performance then you have to remove the PC2100.
Be sure your board supports the speed you buy.
I'd recommend getting the fastest RAM your mobo can run to (or the fastest you can afford if you plan to upgrade the mobo). That way if you want to run the RAM faster at a later date you can buy another stick of the same and swap it with the slower original one.
so itll be alright if i bought the stick of 512mb ddr400 ram, and ran it along side the 2x 512mb ram, but itll run at the slow speed of pc2100????
if thats the case, ill buy the ddr400 ram, and just run it and that way, like smurfette sed, ill take out the old shitty pc2100 ram sticks once i upgrade :)
thanks for all your replys guyz :D
You'd need two sticks of DDR400 though wouldn't you?Quote:

yer when i upgrade to 2 sticks of 512 ddr400 ram.
but for now im asking if itll be alright if i just stuck 1 stik of 512ddr 400 ram along side of pc2100 ram.

Remember to get the other ram from the same company, same specs, to get as close a match as you can.
I take it your going to be running things in dual channel?

sorry, i dont know what this means. could you explain it to me plz :PQuote:

do i have to get the same memory from the same company, same specs etc, for it to work? can i not have a totally different RAM stick in there?
Your Asus A7N8X-E Deluxe board supports Dual Channel Memory Architecture.
http://usa.asus.com/prog/spec.asp?m=A7N8X-...Deluxe&langs=09
Check in the users manual for more information on how to use it.
Basicly you need 2 sticks of ram to use it. One stick in each channel.
The purpose is to improve bandwidth to the RAM and thus improve performance.
Yep, VB hit the nail on the head there.Quote:

And also, for things like dual channel, and usually any second or 3rd stick of ram should be as close as a match to your first stick.
Thats also why they sell 'matched stick' sets on places like newegg, for more money than buying two stick individually. Usually because they have been tested, or specfically picked out to go with their counterpart.
thanks john and VB, u tort me a thing or 2 today
:)
No problem, dray_02. :)
What have you decided to do?
That means its' better to have two sticks of 256 MB than on with 512 MB, right ?
P.S.
I have 256 MB RDRAM (2x 128MB), PC800, on my ASUS P4T (i850 chipset).
1 of 2 sticks (they are same):
Memory Module Properties
Module Name Samsung MR16R 1624AF0-CK8
Serial Number 3A8FD604h
Module Size 128 MB (4 devices, 32 banks)
Module Type RIMM Module
Memory Type RDRAM
Memory Speed PC800 (400 MHz)
Module Width 16 bit
Module Voltage 2.5 V
Memory Module Features
HeatSpreader Present
Thermal Sensor Not Present
Memory Module Manufacturer
Company Name Samsung
If I want to upgrade my RAM (from 256 MB to 512 MB), do I have to buy the same two sticks (or one stick) of PC800 RDRAM that I already have,or can I combine my current RDRAM with an additional stick (or two sticka) of 256 DDRAM ?
P.P.S
My mobo supports up to 2GB of RDRAM
B)
RDRAM has to be used in pairs. Always. No choice.
With some DDR mobos, it is more efficient to use them in pairs, but is not necessary for successful operation. This is because some chipsets handle dual channel ram with a true dual channel controller, which means you can use a single stick. Others use two single channel controllers which means you need a stick of memory for each controller. If you only have one stick then only one controller is used.
