1 gig of ddr ram seemingly a slowdown...


Recommended Posts

I started out with 364 MB of SDRAM, and I decided to go ahead and make the switch to DDR (My system supports both). I went all out and bought 2 - 512 MB DDR 2100 modules, only to find that my system seems to have slowed down. I haven't ran any benchmarks and this could be speculation, but if nothing else I'm not thrilled by an increase in performance. Any ideas? Suggestions? Thoughts on this matter?

perhaps you had cas2 ram and bought cas2.5

Turns out that whenever I first installed the modules and watched as BIOS started, it detected the entire 1 gig of DDR. Now it says that I have 768 MB of ram (as if I have 1 - 256 MB module and 1 - 512 MB module). I'm not sure what's up with this damn thing.

Sounds like faulty ram. Have you tried swapping their positions? It might properly recognize them that way, but even with 768, it should be a lot faster than your old set-up.

swapped umm and i get the 1 gig now. not sure why it really matters as they are identical chips, but oh well. it probably is faster, it's just not the boost i would have expected for 180 bucks you know?

doesn't the ram also need a few days to get into groove with the system, i know when i put a second stick of 256 in this it was a bit slower then after a few days it got faster , same when i upgraded the ram with my sisters computer

that would mean that the ram physically changes to meet the system...not likely

if you have 3 slots for ram try sticking them in 1 and 3 since they draw power from different sources.

i was having a lot of weird memory related crashes and i found that doing this solved them all.

hmmm,

i was always the guy that falls asleep at the back of the lecture theatre whenever certain hardare points came up, but im pretty sure i remember there being a discussion on the implications of too much ram.

feel free to correct me ;)

ram acts as the go between for the cpu and hdd. basically it fills up with data from the hdd and allows the cpu to have much quicker access. but what if you've got so much ram that it takes extra time to fill it up with data...then that would have a negative affect on the system and cause it to slowdown a bit.

this is all speculation, ram and cpu structuer was never my forte, so any1 can feel free to step in and slap my hands if im wrong.

btw,

you havent told us much bout ur system?

what os u using? and what tasks do u use ur system for?

(Could it be 98 or ME that ur usin:alien: )

thats all i can think of, not sure if it;ll help :D

oh and i had the same prob with a stick of ram not always being detected. definately sounds like youve got dodgy ram! might wanna have that replaced sharpish.

good luck matey
