what is the performance increase in going from pc2700 to pc3500 with the FSB at 433

[GreatDaleness]

Ok got my locked barton 2500+ last week. Running at 433mhz fsb no problems. What kind of performance increase would I see by replacing my pc2700 memory with pc3500 so that I could run the memory at 100% fsb rather than 75%? Secondly, what would the performance increase be between cas 2-3-3 PC3500 and cas 2-2-2 PC3500 (Mushkin level 2 pc3500)?

to sum is up
Right now ---- FSB 216 memory 162 cas 2.5
$120 -------- FSB 216 memory 216 cas 2-3-3 How much faster?
$160------------ FSB 216 memory 216 cas 2-2-2 Worth the extra $40?

I don't know bro.....

But I just put in another 512mb ram in my PC and the difference wasn't very noticable.....computer is a little quicker but nothing special over what it was at 512.....

Im running PC3200

Dale, you're going to get roughly a 25% performance boost, just by running your processor and RAM at the same speed. Plus, you're gonna get around 10-15% more by using CAS 2 ram, instead of CAS 2.5 ram. Don't spend the extra money on the 2-2-2 though. Put the money toward something else. Oh, and make sure you set your ram to run 2-3-3-7 in the bios. You will actually get better performance from that than you will with 2-3-3-5. I can't tell you why, but that has been my experience...

I am sorry but I have to disagree.

I went from running my barton at 200 mhz, with pc2100 ddr at 133 mhz (400fsb, 266 RAM)

Everyone here told me I would see a 25% performance increase so I went to PC3200.


Guess what? I only saw an increase like that in RAM benchmarks. in real world performance and other benchmarks I saw no difference

It certaintly didnt FEEL any different. As far as cas2 vs cas3 you will not feel any real world difference there, you are basically just buying a better synthetic ram score in sandra, which is a wast in my opinion. You will not notice the difference.

false. 0-10% depending on application.

CAS 2.5 my machine took 6 hours to do a SETI work unit

CAS 2.0 my machines takes 4.5 hours to do a SETI work unit.

While it was pretty dramatic for SETI, there isn't much noticeable difference running other everyday tasks and apps.

Hmmm thats an interesting difference. However, I dont really care how long seti units take lol
but thanks for the input!

One could say... "I don't really care if you felt any difference, but thanks for the input"

His expereince and opinion is just as welcome as your's.

I suppose, one could say that, if thats what they meant. However that is not what I meant, so that's not what I said.
I said what I said, because what I said is what I meant.

And that is, Seti isnt a concern for me, however I appreciate his input, which was in fact an indication of my value for his input and opinion.

You need to relax.

Well, your experience may be different (read the small print!), but I actually saw a dramatic difference when I swapped out the PC2100 (2.5-3-3-6) that I had to use at first with the PC3700 (2-2-2-5) that I have now. Of course it's only going to matter with the programs that use and need fast ram. I actually didn't notice any difference at all while I was using MS Word2000! Oh, and running your ram out of sync with your processor is by far the worst way to do it, unless you have a P4. With Intel, you can run a 2.4B or C at 3.5Ghz with PC1600 ram!

I didnt notice much of a difference running in sync. However, I am trying to find some decent RAM right now and offload the slow corsair stuff I have now. I mean, it isnt THAT bad. I think im running it at 2.5-2-2-7 which is decent for ram rated at 3-4-4-8

However I would like to get some Hyper X or XMS

I am leaning towards MUSHKIN level 2 PC 3500. I doubt I'll ge much more than 216 FSB out of my NF2. I'll do a 3dmark2001 and 2003 and post the results when I get the memory. I'll post SETI as well. The MUSHKIN level 1 does cas 2-3-3 and level 2 does 2-2-2 for $40 more. I don't plan on upgrading anything other than memory till March, so the extra $40 wouldn't go anywhere else anyway. THank you all for the input!
