my P4 2.4c giving up early?

[MrMiyagi]

I'm a newb overclocker, and have read some of the basic guides. What I understand is I should be able to bump the FSB a decent amount before I gotta start messing with timings and voltages.

Running:
Abit IC7
P4 2.4c
Corsair PC3200 XMS 2x512
Fotron 450w

Just started messing with it today and I can only get the FSB to like 220 (a clock of 2.64 Ghz). This is when windows boots, but quickly restarts. What's the deal? I thought these old 2.4c's did a decent job OC'ing...certainly better than a stinking 200 Mhz OC.

You guys think something somewhere is bad on my system?

I believe the Abit IS7 MOBO is the master overclocker. Not sure about the IC7. Did you try a divider first? Also, does the MOBO support PCI/AGP lock? If not, you need to set that.

Check your bios. The IC7 was considered the best at one time. My 2.4C does 3.3 quite easily (well over 2 years now).

Your mem is crapping out - you need to adjust memory to 5:6 or even lower.

I agree with Zebo, it's more likely your ram, you need to eliminate the ram as the limiter by setting it to a lower divider and you may need to increase the vcore as well, but I wouldn't go higher than 1.6v with a northwood.

I see, from reading some OC's of the same proc I just assumed I could bump it up quite a bit without changing the divider..that's why I thought something was wrong.

My options are 1:1, 5:4, and 3:2. got it at 5:4 right now and doing 2.8+ ghz.

When does the divider setting actually make it not worth the OC? (or maybe it never does, not sure)

Thanks
