iv been running my Barton for a long time now with the below settings. Abit NF7-S V2.0 Mobo, xp2500 mobile @ 200x11/1.525v, 2X512 crucial Pc3200/11.2.2.2.5 idle 41c so i had some spare time and dissided to see i could push it some more. hears the final result, or i should say what I'm happy with xp2500 mobile @ 217x11/1.6v, the problem i have is i can't seem to be able to tighten the ram timming, can only use the aggressive option. any help? xp pro/sp 2 120gb hdd plextor dvd-r mats---a dvd-rom Abit NF7-S V2.0 Mobo, xp2500 mobile @ 200x11/1.575v, 2X512 crucial Pc3200, MSI X800 Pro-TD256 AGP 256M PA9C-42CU cooper hea

Your RAM timings are tight. Try 2-2-2-11 or 2.5-3-3-11 w/1T command rate.

sorry i should i was't able to keep 11.2.2.2.5 after i uped it to 217 fsb. "w/1T command rate" ?? what do you meen ;-) xp pro/sp 2 120gb hdd plextor dvd-r mats---a dvd-rom Abit NF7-S V2.0 Mobo, xp2500 mobile @ 200x11/1.575v, 2X512 crucial Pc3200, MSI X800 Pro-TD256 AGP 256M PA9C-42CU cooper hea

The NF7 is a damn good Socket A motherboard from Abit, I remember back in the days with my Socket A, I was able to overclock a mobile chip quite high. The unlocked multiplier on mine was pretty cool. ;-) P4 Prescott 478 2.8 1024MB GSKILL DDR400 RADEON X800GTO AGP 2x320 SATA SEGATE INTEL D865GLC

This will explain what command rate is: http://forumz.tomshardware.com/hard... I don't know if your board has the option to change it or not. If not, try using CPUZ to find out what the default command rate is & check that the CPU & RAM are running at the same bus speed (1:1 ratio): http://www.cpuid.com/cpuz.php Also, you mentioned the "aggressive" option...you should be using the "expert" setting for both memory & system performance. Make sure to lock the AGP at 66MHz (possibly 67MHz) & if there are any Spread Spectrum settings, disable them. And if you're running an SATA HDD, it will limit the ability to overclock somewhat.

Why don't you try to +0.1v on your dimm voltage to see if you can get 2.5-2-2-11? I think most DDR400 memory can handle all the way upto 2.8-2.9v...

i had a good look around the bios but i could't see a option to change the command rate. cpuz showed bank cycle time and everything below it including command rate, empty boxs, greyed out? so i booted up Everest Ultimate 2007. hears a small sample of the read out.
