Athlon XP 1700+ T-bred A -- FSB speeds?

I currently have mine at 1.7 ghz-12.5x136. I've heard that people have gotten the FSB up to 166, but I run unstable at 138-140 (not terrible, but it occasionally froze while I was accessing the BIOS). What could the problem be? I have Asus A7V333, with 512 MB 2700 DDR RAM. Maybe turning down the speed of the RAM and turning up the FSB? Any ideas?

EDIT: My temperatures are not high either, around 50C with Q Fan (speed based on temp) on (average RPM 3200 with this on), but like 40 with this off (about 4800 RPM).
 
well, I have the a7n8x and the same processor.

What I did was immediately jumped up to 166 but lowered the multiplier all the way and left it that way for a few days...then i upped to multiplier by .5x each time and let run p95 straight for two days.

then i couldn't hit 10.x so I upped the vcore to 1.6 and that is where I am currently at.

try that

also, what kind of ram do you have?
 
I just got the Epox 8rda+ and have the same cpu (AIUGA core).
I'm running at 9x185 right now with 2 sticks 256mb Crucial pc2100. vcore at 1.625. definitely lower the multiplier and up the fsb beyond 166 when you're ready....

What is the lessest multiplier that you can use on the Epox 8rda+?
it be nice if you could run at 200FSB 😀
 
Least multiplier is 4 (if I remember right) and yes, it would be nice to hit 200. I probably could by going to 8 or 8.5 but 9 is at it's limits now. at 8 I'd be running 1600mhz and then adjust the mem back down to around 140-145 (it's at 148 now but I'd like to keep it a little lower, it's only pc2100 after all).

yeah but you have to remenber that you running you mem in a dual set up
AMD XP used a PC2100 mem speed at stock
Dual PC2100 runs at PC4100 mem speed at stock two times as much as the stock CPU can use
I would go for the higher FSB to get more mem speed
 
right but the ram is near it's limits at 148. and even if I set the mem back to 133 it still rates out at pc2100 (or kt266A) levels in sandra's mem bandwidth benchmark. by allowing the mem to at least have 140 - 145 the mem scores are equal to pc2700 or pc3200@cas2 levels. there's only so much you can pump into these before you reach a saturation point and I'm nearing it. I'll try 200x8 and see what's what but not till this set up has some time to burn in.
 
I have it at 145x12 now, and it seems to be stable, but my BIOS locks up when I access it. Should I go back, or is there something I can do to fix this? I'm running Prime95 at the moment, no problems yet (up near test number 500, the second group), and I will probably test it more. Anybody have any ideas?

Edit-and this is only with higher FSB settings. With 136x12.5 I have no problems. at 150 Windows XP freezes right as the loading screen comes up. Motherboard, maybe? But I thought the A7V333 was fairly good.

Edit2-I just found that I CAN access the BIOS screen. I will try one more time, if it's stable, I'm ok, I just don't want to take any chances.
 
A7N8X here, running XP1700+ (Tbred-A) at 9x203MHz
It's faster than 11.5x166MHz!!??
At least 3DMark'01 and UT2003 confirmed it.
