Hi all.
I thought i would try some more overclocking on my tbred B xp1700 (1.6v). I had it running at 2.088 stable on a NF7-S (v2.0) but wasnt happy with the fsb (174.) With pc2700 sammy RAM
This morning i put the multiplier to 9.0, and got the fsb up to 194 @ 2.6v (default) and 2.5CAS. This generated the following error:
RAM parity error - checking for segment...
Offending segment:
F800
Press F1 to disable NM1, F2 to reboot
System halted (Ctrl Alt_DEL to restart)....
Having not had this error before i rebooted (NOT pressing F1.) I then put it to 2.7v and 8-3-3-3 on the timings. This booted windows fine, but rebooted in the dragon benchmark in 3dmark2kSE.
I am going to losen the timings when i get home (as they are on aggressive) to 8-4-4-3. Will this help?
This RAM has been at 200fsb, on a kt333 board. Is the dual channel set-up that i am running preventing it from getting to 200fsb?
Thanks very much
Will

Each mobo handles things differently, since PC2700 is only designed to run at 333mhz (2x166) and you want it synced to FSB you can't really complain. The Dual Channel nF2 will be a good 5% faster than your KT333 even when running at the same FSB speed, IMHO stick close to 333FSB and just use the multiplier to get more out of the CPU. RAM timings make very little diff, esp on Dual Channel as that mostly reduces latency on SktA anyway, just set it to what's known to be stable.
Around 2.1ghz is VERY nice and so is nF2 Dual Channel even if 'only' at (or close to) 333FSB. 1.65v is actually normal voltage for TbredB and Barton (AMD set it lower) so setting this may get you a little higher and is not truly overvolting at all, just be sure your cooling is up to the task. 400FSB is nice but overhyped, SktA simply doesn't need it, not worth bothering with if you already have PC2700 and can get good speed from your CPU.
So basically, it is most likely that your RAM is less happy running o/c'ed int he nF2 compared to KT333 but your overall perf is way higher, don't worry!
im using 194 atm, but it rebooted half way through 3dmark2001SE.

'Spread Spectrum' is to do with lessening emissions and interference with other electrical systems ... leave it off as it sucks big time and often prevents stability esp when o/c'ing.
