worth replacing DDR266 with DDR400?

I have 768mb of Crucial PC2100 running with an Athlon XP 2400+, which is mildly overclocked to roughly 133x16. I previously tried overclocking via FSB but hit lockups and BSOD on 1 extra FSB, I'm kind of hoping the RAM was the issue.

I was wondering if getting two sticks of 512mb Crucial PC3200 and dumping the stuff I have now would be worthwhile? The increase in quantity would be negligible, lets ignore that, I'm just interested in how much better 200x11 or 166x13 (or whatever i might get with the new setup) might be over 133x16.

Mobo is NF7-s and heatsink is thermalright SK7 + panaflo L1A. I would be wanting this ram to be getting carried over to an AMD64 mobo/cpu upgrade in maybe 6 months, I'd probably be buying whatever cpu is about the price the 3200+ or 3400+ is at now.


I'm looking at gaming performance only. Is the spend worthwhile?
 
What videocard do you have?

What would be the bottom line upgrade cost for you to acquire this new ram (you planning on selling the old ram, if so for how much?)

 
I'm not sure upgrading just the RAM to DDR400 would help much, while using your current CPU.
If you plan on upgrading the CPU later to a 64 or something similar, then it's definitely worthwile.

if I had that system, I would be using the PC2100, as buying faster RAM just to run at 200 instead of 133 IMO doesn't make that much of a difference. Mind you, memory is cheap, but I don't think your system would be screaming fast compared to what it is now anyways. AMD CPU's like to run 1:1 FSB:memory, running Asynchronous can actually decrease performance.

Might want to search for some benchmarks to be sure.
Your call.
 
vid card is a mildly overclocked 9800pro

Since all I would be doing is buying the new ram, it'd be £100 ($200, but the current dollar value makes this look a fair bit more than it is). I doubt I could sell the PC2100 really, other than what i'd be doing anyway when I do the big upgrade, which is sell it with the cpu and mobo when putting together a basic PC for someone.

CraigRT I'd be planning on running ram & cpu in sync, i'm not sure how well these 2400+'s are coping (or performing) with trading multiplier for FSB and running at the same total mhz. My thinking was that if games would perform noticably better, particular in reducing those FPS dips on cpu-bound games like ET or HL2, then it is liable to be worth doing since I'd just be buying the same ram in 6-12 months anyway when I do the big upgrade. that is, assuming the Ath64's would still be using a 200mhz FSB and that ram prices wouldnt drop so that PC4000 became as reasonable as the crucial PC3200 is now, as that'd give me a bit of OC headroom on the new setup.

thanks for info tho, I'm thinking against going for it now.
