1024 Ram Vs. 768

[DaZednConFuZeD]

Hey guys, I have a P4 1.8 OC'ed to 2.35 on 1.60V, a Asus p4p800 Mobo, Radeon 9800 Pro 128, 1 stick of 512 Spectek PC2700,1 stick Spectek 256 PC2700, and some kinda Nanya(crap) PC2700 256.

when i looked at the latencies it was 2.5-4-4-8 @ a 3:4 divider as my CPU is running at 130MHz.
I know that with the two sticks of Spectek can run at 2.5-3-3-6 or 2.5-3-3-7. I was wondering if it would pay off if I decided to remove that Nanya stick of ram to get my latency a little lower, and was wondering what kind of effects that would have on my system running 768mb or ram as opposed to the 1024? Thanks so much in advance :beer:

Go with the 1024. The speed difference will be negligible for timings, but it will be quite pronounced if you run out of ram.

go with the 1024, more ram is always better!

Cool thanks guys.

I tried taking it out just for fun anyhow, and found that I was able to OC the CPU further to about 2.45, but then game stability and benchmarking on 3dmark01 was noticeably lower. So i guess my conclusion is that similar or better ram allows for better OCs, but on games, you're going to suffer eh?

Thanks again!

yeah, unless having more RAM *severely* cripples your OC, 1 GB > 768 >> 512 in games.

 

[Bassyhead]

more is better

dude, running the 2x256 and the the 1x512 is dual channel. that will boost ur performance ALOT.

I thought that in order to run dual channel, you would have to have 2x256 of the same sort and speed ram? Also, don't you have to have all ram chips of the same size? Like, I couldn't run 512 in single and 2x256 in dual right? just me 2 cents :beer:

For dual-channel mode on an Intel-brand dual-channel chipset like i865PE, i865G or i875P, you need either a matched pair of modules, or two matched pairs of modules. You could have a pair of 256's and a pair of 512's, or four 256's, or two 128's and two 512's, etc. As long as the modules within each pair match eachother in their logical addressing scheme, you're ok. Mixing single-bank and double-bank modules would be one sure-fire way to disable dual-channel mode, however.

When in doubt, buy some new matching modules and sell off the old ones, that's what I say

 

[DaZednConFuZeD]

My thoughts exactly MechBgon, thanks for clarifying that. I'm going to upgrade my processor soon to a P4 2.4C 800 FSB and overclock the SOB so i believe i'm going to sell my current ram and invest in some either OCZ PC3500 2x256 Dual Channels EL or Mushkin Lvl 2 2x256 PC3500's (if i can find em) doh. But yeah i think that should work ok... hehe we'll see , thanks again all!

hmm, i got some of that nanya rubbish in my spare rig. the memory chips itself are made by Elixir which personally dislike, but hey, that's what you get for generic stuff. you should be able to run 2.5,3,3,6 on that nanya stuff especially if it's PC2700. i got a 512 stick of PC3200 by nanya and it works fine @ 2.5,3,3,6
