Paranoid Posted March 3, 2004 Posted March 3, 2004 I have gooten my 2800+ to 245MHz FSB, so I would try it out and see what you can do with it. Share this post Link to post Share on other sites More sharing options...

Paranoid Posted March 3, 2004 Posted March 3, 2004 the hyperX pc4000 can get u up to 523Mhz. PC4000 is rated for 500MHz. Share this post Link to post Share on other sites More sharing options...
JackRussell Posted March 3, 2004 Posted March 3, 2004 From what I've read you can run the mem a little bit higher than rated speed... so supposedly 523Mhz (but no higher) would be ok. Is that wrong? Share this post Link to post Share on other sites More sharing options...
ccokeman Posted March 4, 2004 Posted March 4, 2004 My concern is the timings as they are 8-4-4-3 can they be run a little tighter at slower speeds? Share this post Link to post Share on other sites More sharing options...
JackRussell Posted March 4, 2004 Posted March 4, 2004 My concern is the timings as they are 8-4-4-3 can they be run a little tighter at slower speeds? I'm not yet too experienced with messing with timings, but can tell you I previously had them at 8-3-3-3 at fsb's 200 to 230... I think a few freezes may have been caused by that at higher fsb. Now I have 8-4-4-3... I'm still on learning curve with how these timings play with OC. Share this post Link to post Share on other sites More sharing options...
Nuclear Posted March 4, 2004 Posted March 4, 2004 You really can't play with RAM timings too much on PC4000 or higher RAM. It has to run really loose timings to achieve those speeds. PC4000 is good for people who don't wanna vmod their boards (don't blame them), it can run 1:1 really high out the box. I prefer juiced PC3500 over PC4000, but I don't mind vmodding or burning chips. I scored almost 6K with PC4000 1:1 at 250FSB 2.7v with loose timings, but I scored 6317 with PC3500 1:1 at 250FSB 3.2v with tight timings. Like I said though, I don't mind risking my chips for tight timings and high voltages. Share this post Link to post Share on other sites More sharing options...
JackRussell Posted March 4, 2004 Posted March 4, 2004 Cool much appreciated... Wasn't clear yet on why exactly folks end up messing with DDR volts. So all I'll be raising is vcore. I'm Prim95-stable at 230fsb with stock volt right now. My next step to 235 will need at least 1.55 vcore (tried already; it rebooted by itself after XP login at stock 1.52 vcore, but not with 1.55v). Just need to find time for hours of Prime95 before I go 235fsb (want to watch it initially). Share this post Link to post Share on other sites More sharing options...
FanATIc205 Posted March 4, 2004 Posted March 4, 2004 the 4000 will be fine. i found latencys on the nf2 do make a small performance increase but nothing that you could actually percieve in games and apps. Share this post Link to post Share on other sites More sharing options...
ccokeman Posted March 5, 2004 Posted March 5, 2004 It was waaaaayyy slow .I thought it would be fine at 7-3-3-3 but it just took double the time to open and run everything. I dunno what went wrong but it was way wrong. Ill try some pc3500 and see what i get. Share this post Link to post Share on other sites More sharing options...
