2100 woes

[ManDooM]

My current proc is a T-bred B 2100+ oced to 166mhz * 13. I only had to bump the voltage from 1.6 to 1.65. I'm using an SLK-900A with 92mm Vantec Tornado. The fan is throttled down to about 1/4 the full speed (2500 rpm) and I'm getting temp of 41C under load. For some reason I can't bump the FSB by a single more mhz at *any* voltage from 1.65 to 1.9 without a freeze up. But it hasn't crashed once in all the time I've had it at this setting - almost a year.

Have I hit the wall? Temp is never a problem and I use the Vantec Ion 400W psu that is steady as a friggin rock. I/O voltage is locked at 33/66 and my memory is DDR400 Corsair XMS. I haven't tried lowering the multi yet and I'm kind of unsure how. Maybe I'll have to finally submit and lower it some?

NF7-S rev2 (latest BIOS)
1GB DDR400 Corsair XMS
WinXP pro

You may have hit the wall for the CPU. I knew of a 2500+ barton that wouldn't budge past 185FSB.

try one of the beta bioses with the L12 mod built in.

i couldn't get above 166 mhz either until i tried a beta bios.

now i'm running 214 at the moment.

You have PC3200 memory; why are you not running 11x200 instead of 13x166?

You'd have the same CPU speed, but a much faster FSB. Your overall performance would be increeased nicely.

FWIW, I have an older XP2100 myself, and it totally maxes out at 2.100GHz. Taht's at 1.850 volts and it runs hot as a mutha.

OTOH, 10x200 for an even 2.00GHz runs smooth as buttah at only 1.750v. Stable as a rock.

I don't think that the CPU itself is the blockage. Most any T-Bred B XP-2100+ (especially the AIUHB cores) will hit 2.4 Ghz without a sweat. The T-Bred A won't do well at all in comparison, some not even hitting 2.1 Ghz.

The 2100+ T-Bred B was/is one of the better OC CPU's available, and with TEC or Phase Change, these chips have hit 2.6 Ghz. Most all these chips hit around 2.45 Ghz on air cooling.

But I thought a T-Bred would have no problems hitting 200FSB? Unless they have em lock just like the new sucky Barton 2500
