Will i see a difference going from SDRAM to DDR?

[TFM]

Right now, here is my system:
P4 533 M/B
Celeron 1.7
1x512 SDRAM
9800 Pro Video
40 GB HD
Windows XP Home

I am involved in a trade right now that will substitute my 512 SDRAM for 512 Mushkin High Perf PC2100 (my m/b will handle 2 sticks of SDRAM or 2 sticks of DDR RAM up to 2GB for each)
My question is this, will i see a difference by upgrading the RAM? If not why not? Is it b/c the Celeron chip will still hold it back? Or is it b/c the DDR 2100 just isn't that much of an upgrade? I'm curious to know, any help would be very much appreciated!

Thanks,
Chris

Bump - no one has any thoughts?

Asuming you keep your system pretty much as it is, apart from a new Mobo and the DDR ram, in most situations, there will be no difference. Howver in more intensive situations, upto a 10-15% performance difference will be noticed. For example game. If i got 100fps with SDR, then i`d likely get 110-115fps with DDR.

you'd see more increase if you had a P4, but you will notice increase in FPS and things like that, rather than actual "feel" of performance.

I didn't notice a HUGE difference, but it was there. Most likely my hard drive being the weak point now.

id rather upgrade that celeron than the memory.

but memory is the cheapest and fastest way to upgrade any computer. .. that's the saying .. don't know if that applies to SDRAM > DDRRAM

Going from SDRAM to DRR is like going from a 1980's Honda to a late model Honda Accord. It's alot faster!

 

[imported_Phil]

He's not asking how fast it is, more on how much of an impact on system performance will be.

 

[cockeyed]

First, trade the SDRAM for DDR, then, when you can, replace the Celeron with a 533mhz P4 2.4ghz or greater; the new memory would give the P4 the memory bandwidth it needs. To change one without the other seems pointless to me. The 9800 pro is really being held back from showing its true potential in your current system. You need to un-choke your system!

If you plan to stay with the Celeron, DDR would be of little benefit.

Seriously, that 9800Pro might as well be a GeForce3 in your system. The Celery and SDRAM are killing it. I wouldn't be surprised if you saw nearly a 75% increase in gaming performance just putting in a cheap 2.4 P4 and that DDR.

SDR ram aint as "slow" as you lot are making out.
At best its 15% slower than DDR. At the very most.

A friend of mine has a Celeron 2.2 or 2.4 (I can't remember) with SDRAM. He said he overclocked it to 2.8 and used a divider to get the higher FSB. He said it was SLOWER than it was @ stock due to the reduced memory bandwidth. Since the celeron has such a crippled cache, it has to go to memory more often than a P4 does for data. This means a celeron w/sdram will see an even bigger performance hit than a P4.

 

[Ionizer86]

Yes, the DDR would help a good amount, but even more so if you used a P4. The i845 SDRam platform was just really bad. It choked up every chip to about the speed of a P3 1.0-->1.2.

Wow - thanks for the info guys. Kinda what i was expecting ... with some things i didn't realize. Just so you know, it is in the master plan to eventually have this system ...
P4 2.8 533 fsb
1GB DDR RAM
9800 Pro video
40GB HD
Windows XP

I just can't do it all at once, so the wife let me do one upgrade for X-mas so of course i chose the 9800 and got it out of the way. That's why i have the celeron for the time being. I just wanted to know if i would see a difference, or if it would take upgrading the CPU as well to see a difference using the DDR over the SDRAM.

And any suggestions anyone has, please let me know - thanks.

What I would like to know is why on earth do you have a 9800 pro in such a crappy system!?!? If I were you, new RAM, new Proccessor, New Mobo, and new HD and you have a much better system

 

[BFG10K]

You'll see a decent difference but you'll still be severely bottlenecked by your Celeron.

Get rid of that single-channel motherboard (probably SiS-based or ALi-based) and get a good dual-channel-DDR board, something with the i865PE or i875P chipset or the new SiS 655TX chipset. Anything less than dual-channel PC2700 is going to be doing your P4 a disservice.
