Crimson 0 Posted January 25, 2004 Share Posted January 25, 2004 (edited) Quick question regarding RAM. Which of these offers better performance: 3x 256MB DDR PC2100 RAM (768MB) 2x 256MB DDR PC2700 RAM (512MB) Thanks for the help.

snakebite1967 0 Posted January 25, 2004 Share Posted January 25, 2004 pc 2700 or higher buy what your mobo will support Quote Link to post Share on other sites
WhiteKnight77 1 Posted January 25, 2004 Share Posted January 25, 2004 Well if you have a motherboard that supports dual channel RAM, go with the 2 sticks of PC2700. Quote Link to post Share on other sites
Crimson 0 Posted January 25, 2004 Author Share Posted January 25, 2004 @WK (Or who ever see's this first.) What does duel channel RAM offer/do that's so great to neglect an extra 256MB of RAM? Quote Link to post Share on other sites
Dark Ranger 0 Posted January 26, 2004 Share Posted January 26, 2004 It really depends on your CPU/FSB though. It's nonsense to put in DDR-400 in a machine with 266FSB (133 actual) support. You're just wasting your money. As far as Dual-Channel capabilities, it basically doubles the effective read/write performance and bandwidth of Single-Channel ram. IMO, you'd want to obtain a perfect 1:1 ratio. For instance: - AMD or Pentium CPU running at 133FSB would pair with DDR-266. - AMD or Pentium CPU running at 166FSB would pair with DDR-333. - AMD or Pentium CPU running at 200FBS would pair with DDR-400. Hope that helps ya. Quote Link to post Share on other sites
Crimson 0 Posted January 26, 2004 Author Share Posted January 26, 2004 I have an AMD Athlon 2500+ w/ 333 Mhz FSB. (So really a 166 I think.) Do you suggest a couple of sticks of PC3200 then? Quote Link to post Share on other sites
Dark Ranger 0 Posted January 26, 2004 Share Posted January 26, 2004 You've got an nForce2 right? Does that model also support the newer 200FSB CPUs? If you plan to upgrade your processor to a Barton/200MHz FSB, you'd be best to go ahead and get the PC3200/DDR-400. If you don't plan on upgrading, stick with 2 modules of PC2700/DDR-333. Perhaps 2x256. Quote Link to post Share on other sites
Crimson 0 Posted January 26, 2004 Author Share Posted January 26, 2004 I've got the ASUS A7N8X. (Love it.) Only supports 333Mhz AFAIK. I plan on keeping the CPU for another half year or so. Quote Link to post Share on other sites
Dark Ranger 0 Posted January 26, 2004 Share Posted January 26, 2004 Yeah, that PC3200 won't really be worth the money for your setup. My advice: Buy yourself the PC2700, keep your CPU for the life of your computer. Next upgrade - 64-Bit platform. That'll cost you a new motherboard, CPU, and Ram. Oh joy.

Crimson 0 Posted January 26, 2004 Author Share Posted January 26, 2004 Thanks for the help fellas. @DR - That was the big picture: the AMD 64. Can't wait to get my hands on that thing. So far everyone seems to love it. Quote Link to post Share on other sites
snakebite1967 0 Posted January 26, 2004 Share Posted January 26, 2004 i run pc 2700 in dual channel mode all it real does is allows the memory to run at 128 bit instead of 64 bit, IE it can answer while its doing other tasks where as in 64 bit mode it will make slower dedicions sposedly. and yes id run less ram if it was a faster ram Quote Link to post Share on other sites
WhiteKnight77 1 Posted January 27, 2004 Share Posted January 27, 2004 The A7N8X can be flashed even if it is an older revision to accept faster FSB CPUs. I have PC3200 in mine for now and will upgrade next year to a 3200+ with a 400mHz FSB. Quote Link to post Share on other sites
Crimson 0 Posted January 27, 2004 Author Share Posted January 27, 2004 The A7N8X can be flashed even if it is an older revision to accept faster FSB CPUs. WK, do you have any links/articles with any info on that? I was thinking of OC'ing my 2500+. Seems that it's one of the best CPU's to OC at the moment. Quote Link to post Share on other sites
WhiteKnight77 1 Posted January 27, 2004 Share Posted January 27, 2004 Go to the CPU Support page at ASUS to see what CPUS are supported on which motherboard and which BIOS revisons are needed for such support. Quote Link to post Share on other sites
