OC-ing an old XP1600+

[AnotherGuy]

Hello everyone.. I have this old system with a non brand Mobo (AZZA) 133/166 FSB an XP 1600+ and 512mb of non brand pci133 RAM. Recently i bought a Radeon 9600XT .. so i decided to OC my cpu a little.
I changed voltage from 133 default to 140, maximum was 166, and everything seemed to be fine for a couple days. Then all of a sudden while i was playin a game (AAO) a black blank screen comes out of the game... and computer not responding. This had never happened to me before... for a sec i thought i fried the Mobo or the vid card or smth... so i restarted it changed the voltage back to 133 and now havent had the guts to try OC it again..
Anyone has any idea what could have caused that blank screen ?
Or, anyone knows what damage can be done when overclocking cpu voltage?

Coz actually i just bought this vid card and its only running in 4x coz of the mobo... and i might be looking for a system upgrade... and i dont want to fry the only good piece that i have.
thanks

It is a palomino. Dont bother overclocking it. The max a pally could get to wont show you much of a difference.

your motherboard wont allow you to overclock stabily either. dont forget that its not a barton core. 2.4GHz on that thing, if you could possibly get it there, would only equal to a barton 2800+.

the Palominos ceiling is about 1.8ghz, 1.9something i think is the all time high.

The crash could have been caused by the new video card too, if you installed it at the same time. But regardless, I think that a CPU of that vintage isn't really worth trying to overclock much. I have an older TBred-A XP1800, that will only really do XP2000 speeds stably, and your CPU is older than that.

Btw, you refer to 133, 140, and 166 as "voltage", when I think that you mean FSB speeds. If you don't properly know the difference between FSB speed and voltages, among other things, then you really shouldn't even be messing around with overclocking, until you read up on the subject a little more. Otherwise, I fear that you could fry something, and I think that you would regret that more.

I suggest running the system at stock speeds for a while, and see if the screen-blackout thing happens again; I pesonally suspect the card more than anything, but perhaps that's because I'm running a Radeon 9200 in this system, and have had strange issues ever since I installed it.

A 1600+ runs 1400MHz by default, if it is a good stepping (AGOIA) it could reach 1800MHz which would be a very significant boost in performance.

I don't have a 9600, but I have owned several 9500 and 9700's and they usually won't tolerate a high agp bus. When you overclock with the fsb on an older motherboard, you are also overclocking the pci and agp buses. If your board has a 1/5 pci divider it should kick in at 166MHz, but this will only work if your cpu is willing to go that fast. If you have any options for changing the multiplier you can try that. Leave the fsb at 133MHz, although if you have to connect all the L1 bridges on a Palamino it isn't the easiest...

Good point, if it is a TBred-A like mine, and not a Palimino, then he could get some OC out of it, but likewise, I don't recommend non-standard FSB speeds that OC the PCI/AGP bus as well.

Heck, I wish my XP1800 would reach 1.8Ghz, but I think that's a bit of wishful thinking for these older chips.

impossible =\
