I have an AMD Athlon XP 2600+ and in the bios it says that its running at 166 fsb, i was wondering whats the normal speed of the Athlon XP 2600+ so i can speed it up, thx in advance...

There are several versions of the 2600+ & they all run at different speeds. Two of them run at 166MHz (333FSB): Tbred core 2600+ @ 12.5 x 166MHx (2083MHz) Barton core 2600+ @ 11.5 x 166MHz (1917MHz) The multiplier is most likely locked, so all you can do is raise the FSB. You should be running at least PC2700 RAM...PC3200 would be better. What board do you have? Asus A7N8X-X 1800+ @ 8 x 210MHz 768MB PC3200 Asus A9550 128MB/128-bit WinME/WinXP Pro

I run the same thing, and changed the FSB to 185 Mhz. Here is another nice article for it: http://www.techtastic.ca/reviews3/barton-2600.html Supposedly, you can even change the multiplier with some pencil markings, but I haven't tried yet. FSB 186 is the last speed before it (the board) changes other RAM settings, afterwards the box did not boot anymore. No screen, I assume the AGP speed gets to high then. 186 was fine initially, but getting instable at times (machine crashed and restarted automatically). 185 seems to run very fien and stable, nothing else changed. Performance with Fresh Diagnose or Sandra indicates near 3100+ performance. The board options in regards to cpu voltage etc. are very limited, and stability is main concern. I might try the pencil stuff in the future, board and RAM support up to 200 FSB, so only the CPU is the limit...

Thanks, ill try to speed it up, by the way i have a ABIT NF7-S2 board. any other suggestions?

Hm, I have a lot of (3-4) crashes today, not sure if it is the new XP security patches, new Firefox, or the overclocking. Set the FSB back to 166. Also realized I actually can block the AGP speed to 66 fixed in the BIOS, probably should do that next time when turning higher speed. Maybe next week...

I think this may explain why my system keeps crashing. I have an Athlon XP 2600+ Barton Core on an Asus A7600-X MB and 256MB of PC2100 RAM. Could this be my problem? How embarrassing.

I have Athlon XP 2600+ Barton core on Asus A7N8X-X motherboard with Asus Geforce FX5200 128 MB. My old RAM 2*128 MB. Whn i used tht the sys on POST showed 1333 Mhz memory frequency. My new RAM 512 400 Mhz Fsb now. Now the sys on POST shows 166Mhz..... I guess 2600+ supports only 166....even tho ther is an option in bios to load it up to 200mhz. But the sys doesnt boot at all fter tht ! Neways I wasted money on 512 400fsb !!! Old is gold ! The thing is sys on POST shows memory frequency and not the FSB mate !
