Im trying to get my hands on some good RAM.. because i have my AMD Athlon XP 1900 shipping soon...

why does some of the ram says.. 2100 DDR RAM ECU
And alot of the others say no ECU ?

what is ECU?.. whats the difference with one with no ECU?

and what brand of RAM would you recommend... please let me know.. just need some advise, for you Athlon XP'ers out there.

thanks...:)

If you don't have ads blocked, you will see a Crucial banner at the top. Support our site and use it. :) Not only can you buy ram but you can read up on different types.

instead of ECU, i think you mean ECC. ECC memory has a parity for error checking. you really don't need ECC nemory unless you are running a server or something. 95% of computers out there have non-ECC memory.

nah
i got ecc ram in my comp
dun ask y
came wid it :p
bought 2 more sticks of 128 both ecc
i think price was the same for ecc and non-ecc
you may want to stick with non-ecc tho
because its a little faster at doin the actual work...not having to check everythin n all
n u probably dont need ecc anyways

you're quite welcome, kucoloco. }:>

and desimatrix007 is right... ecc is effectively 11% slower because it uses 9 bits per byte instead of 8 like non-ecc memory. the extra bit is for error-checking and won't come in handy unless you have multiple gigs of memory or are running a high-end server all the time.

Well aren't the 9 bits parallell as the 8 bits normally are? Why should they be serial? If they are parallell there is no differnce in speed. Where did you find this info?

here's my loose explanation... bear with me...

the memory interface only has so much throughput. for instance, 266mhz memory runs at 266,000,000 cycles per second. so if it's in ecc mode and using 9 bits per byte, less amount of bytes would be exchanged than if they were only 8 bits (non-ecc). they are not parrallel, in that the extra bit is sent somewhere on the side. it's more like these bits are doing a congo line to and from the northbridge.

i can't find a site to explain this. someone posted one a while back but i can't find that thread.

well, he never did specify his mobo model number or anything. and if a mobo supports 333mhz drr (pc2700), then it will support 266mhz (pc2100) also. not sure about anything lower.

Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
