PC1600 CAS2 vs. PC133 CAS2, is either of these faster?

You can get Micron 256MB PC1600 DDR modules rated at CAS2, for only $136 on Pricewatch. It's close to the cost of equivalent PC133 SDR modules (also CAS2).

Is there any disadvantage to the DDR over SDR? How is the comparative performance? (I'm particularly interested in compilation speed and FPU for multimedia.) Thanks for any info.
 
What cpu do you plan on getting? AMD or Intel? Well anywho right now the the DDR ram is not much faster at all then PC133 ram as i'm sure you already know this. They are usually withing 2-3 percent, and i've even seen the SDRam being faster. I'd assume this might be one of the cases because the ram you said only uses 100FSB correct? And the 2100 uses 100 FSB i believe. So i'd use the 133 ram because everything will be running faster.
 
CPU: Tbird 1.1GHz retail.
Motherboard: replaceable! 😉

Informant X, did you mean to say the following is true:
PC1600 = 200MHz = 2x100MHz = forced 200MHz FSB
PC2100 = 266MHz = 2x133MHz = forced 266MHz FSB when using the AMD761 chipset??? Or does it support asyncronous memory speeds?
 
Yeah that's what i meant. Definitly get the PC133 CAS 2 ram. The bus will be going faster which is good. PC1600 is only 100 FSB. You will definitly seem the same performance with the PC133 ram, and in some cases it might be faster.
 
Yeah Leo V my bad...I meant PC2100 uses 133, not 100.

Also, kinda OT, but didn't you make a EMBM emulator back in the day for the Geforce? Whatever happened to it?
 
Well, I put together some stuff and then moved on. What's really bothersome is that later, I sent NVIDIA a demo I created, which allowed completely "free" 2X jittered (3dfx style) FSAA. They really liked it and a guy I know actually implemented a test driver w/it. But they never put it into "final" drivers, possibly for political reasons...I dunno. They actually had asked me to keep it under wraps. I'm guessing they canned it to prevent trouble for the NV20 (which is supposed to be the FSAA king.) 🙁

I've since moved on to experimenting with other stuff like sound 🙂
 
Back on topic: seems like I'm fine right now, then. I'm currently using dual 256MB Kingmax sticks, which work at 133FSB / cas222. Can't wait for the Asus A7V133 to get here via UPS Goat Haul (aka UPS Ground).
