Mixing RAM??

[kmvan0]

Hi,

I am upgrading my computer (desperately need to)and I need some advice. I currently have 256MB (133MHz) RAM (how crap is that!!!!) and I want to stick in another 512. I was looking at a single stick of 512 (400Mhz).

Now, my question is. If I stick them both in, will the 400MHz drop to 133MHz?? If so, would I get better preformance if I just took out the 256meg and used it as a doorstop or what??

Thanks for any replies.


My Specs: P4 2.4 Northwood
256MB RAM
40Gig HDD
FX5200
5.1 Card
DL DVD-RW

It really depends what your motherboard is, Mine downclocked my Ram from PC2700 to 2100

lol downclocked. Scummy as.

the mb might not even support pc3200 maybe maybe not even 2100 since it is 133mhz like you said. if i remember pc133 isnt ddr ram.

 

[ZER0X]

pc133 isnt ddr ram

No it isn't DDR

Ok.

Its a GA-8SIMLH ( http://www.giga-byte.com/MotherBoard/Products/Products_Spec_GA-8SIMLH.htm )

It sez it only supports up to PC2700, so I guess im getting that.

Ok, so if I get 512 of pc2700, will i be better off just sticking that in, or should i take out the old stuff first??

 

[kof2000]

take out the old stuff unless the ram speed matches.

Yer take out the old RAM and replace it with the PC2700

Isn't sdram pc133 a 168 pin module and the ddr is a 184 pin module...I didn't think the slot would be the same for sdram and ddr....


So if thats ur MOBO than u have ddr 266 (remember it's double) pc 2100 on ur MOBO now...


So now u have to decide if u want 512 of pc 2700 or 768 of pc 2100

i say u drop the old stuff.. and go for 512MB PC2700 (256MBx2).. if thats the highest ur MoBo will handle then get the PC2700.. but u should just get a new Motherboard so that you can upgrade a lil better/more!! but if u dont want to buy a new mobo.. then go for the Dual Channel 512MB PC2700..

You might as well get PC3200... its often cheaper
