how high is too high on 2800+

[NavJitsU4]

Hi,

My CPU is a barton 2800+, unfortunately i got one of the locked ones, which means the multiplier is stuck @ x12.5 and the stock fsb is 166(332).

I have PC3200 Ram and I can get stable performance @ 195(390)FSB, my question is: is it safe for me to leave it at this speed? I have sufficient cooling; the highest temp is 55-57C. Considering all of these factors can i leave it at this setting and not worry about hardware failure?

-Any help/suggestions is well appreciated.

55-57C under load isn't that high for your overclock...what kind of voltage are you feeding that thing?

I haven't fooled around with the vcore yet; it's at stock 1.650.

Wow, that's pretty impressive to get 190 FSB out of a locked 2800+ at the default voltage. Several of my friends have the same chip, and they can't seem to get much higher than 180-ish FSB, regardless of the voltage.

Nice OC for air cooling! I'd run some stress testers like Sisoft's sandra, memtest and prime95 before calling it stable. If its stable after hours/days of running these tests, you should be fine at this speed unless you wish to go further. Due to your heat, I'd say 200 max

At 195fsb your running your pci bus at 39 thats higher than I like to run mine. I have a Sempron 2200 on a mobo that only goes up to 199fsb and it will overclock right up to 197 but I keep it at 180(36pci bus speed). If you can bump it to 200fsb(try a little more cpu voltage) it will kick in the 1/6th divider and bring your pci back into spec(33)

hmm...i must have an overclocking monster because i run my sempron 2400+ at 200 fsb with the stock hsf.

Umm, the sempron 2400+ is a wee bit different from the barton 2800+

sempron 2400+ is 10x166 = 1666 MHz and 200 FSB = 2000 MHz That's pretty much a 1700+ T-bred which was pretty much a gimme at 2000 MHz
barton 2800+ is 12.5x166 = 2083 MHz and the top end AXP is 2200MHz. 200 FSB would be 2500 MHz.

2500 MHz is not typical for any barton, especially not desktop bartons.

I'd be surprised if MANY semPR0N 2400+ processors do NOT make 200 FSB. The barton 2800+ is a completely different animal though.

195 Mhz FSB, sounds like a very good overclock. I can't push the FSB beyond 171 with my 2800+ Barton, although I have a very cheap motherboard.
