BUT, even if it's a T-bred B, you're going to have to raise your ram's timings to at least 2-3-3-6. Plus, I would raise the vcore to at least 1.70v, and probably to 1.75v.Originally posted by: shady06
it depends on the stepping. is a tbred A or B?

edit: Since it posted at 1.65v, you probably won't need to raise the vcore higher for 10x200, but it's possible that you may. The reason I would raise the vcore to 1.75v is because quite a few people's T-bred B's run at up to 12x200 on that vcore.

Wigwam, you shouldn't have hardly any rise in your temp, as long as you keep your vcore under 1.70v actual. If it skyrockets, it's because you don't have enough air flow through your case.

Just run it at 1.85V. It won't hurt the processor, it lies within AMD's technical specifications.

the voltage per se might not but it would run damned hot!

V=IR says temps shouldn't increase by more than 12% over 1.65V.

yeah true but that still take me into >60C country....

Technically, if you must know, the better clocking CPUs will be the ones at the center of the wafer, with overclockability falling off the further you are from center. Of course, the location of the CPU cut from the wafer isn't etched into its die anywhere, so you can't really tell where it was from.q]
fair enough. my piece of crap must have been cut from the end of the wafer!
tried running 10x200 [and even 10x198] at 1.75v and no joy: crash city.....
what is frustrating is that i get this speed and above on a lower fsb [12/166] and can run fine 9.5x200 but it doesnt like 10x200 even with lots of juice.
hhhmmmmmmmmm
:disgust:

In my opinion, the way to overclock if you're going for maximum (and you have an unlocked processor you can set the multiplier on), is to adjust the multiplier until you find the highest speed your processor will run stable at. Jot that down. Then set the multiplier low and find the highest FSB and RAM speed you can run at. Jot that down. Divide processor speed by FSB speed and you've got your ideal multiplier. That should give you an excellent starting point.
I ran every Athlon I owned at 1.85V. Never had a problem and I've owned more than a dozen including one heck of a furnace (Dual 2100+ @ 2.26GHz each)

a7n8x deluxe revision 2 [certified to 200mhz fsb]
2100+ t/b B AUIHB
twinmos/winbond bh5 ram
everything is doable on paper - i seem to be missing a trick and cant for the life of me discover what it is

can you run it at 10x200 with one stick of ram or both sticks in single channel? my previous 8rda had trouble running 2x512 sticks in dual channel even though each stick runs well above 200 with memtest. when i ran 1 stick or put them in single channel, 200 was not a problem again. it was sorta wierd...i read somewhere that the memory controller was stressed when running 1 gig in dual channel so it was completely stable. but i don't know how true that theory may have been.

interesting [i think so anyway] answer:
it cant run dual channel with slots 1&3 at 200mhz but can at 166 [loads of memtest errors]
it runs dual channel perfectly happily at 200Mhz 6-2-2-2 in slots 2&3 [no errors in 12 hours memtest] and stable at system speed = 200MHz with 9.5 cpu multi....
admittedly i havent run 1 stick in this way but i dont see why it should make any difference; put it another way, if i have to do that then i wouldnt run the machine on this setting anyway
