Help! Which P4 2.4B chip has better OC'ing potential?

[LiQiCE]

I have two P4 2.4B chips, I need to put one into a system for my parents.

Chip #1:
Runs 100% stable at 2.80Ghz 1.55v idle/actual
Not 100% stable at 2.88Ghz 1.65v idle/actual, boots into WinXP, but will reboot or freeze
Not 100% stable at 3Ghz 1.7v idle/actual, boots into WinXP, but will reboot or freeze

Chip #2:
Runs 100% stable at 2.80Ghz 1.5v idle/actual
Not 100% stable at 2.88Ghz 1.65v idle/actual, boots into WinXP, but Prime95 returns a mathematical error after ~1 hour, otherwise 100% stable
Won't boot into WinXP at 3Ghz, 1.7v idle/actual

I'm trying to figure out if one of the two chips will be stable if I get a bigger/better heatsink/fan, right now I'm using the Intel HSF w/AS3.

They're both the same stepping, SL6EU (b0 core). Both run around the same idle/load temps. I'm just thinking if Chip #1 will boot into XP at 3Ghz it may have more potential, but it isn't really stable at 2.88Ghz while the other processor is semi-stable at 2.88Ghz, it just can't complete Prime95. Right now Chip #2 is in my system, so if it really makes no difference then maybe I will just leave that one in there, and hope I can at least get 2.88Ghz stable with a better HSF.

Either way, with the Retail HSF, it doesn't sound like I'll be able to get anymore than 2.8Ghz ...

Thanks for any help in advance!

Anyone have any ideas? Any help would be appreciated!

I guess it doesnt really matter that much. Most p4 are voltage limited anyway, not heat limited. So a better heatsink will probably not increase your overclocks anymore. Just be happy with running at the helafast speed of 2.8ghz.

Sure beats my pII 400

I'd be happy if I could hit 3Ghz ... I'm so close! But 2.8Ghz is definitely nothing to scoff at.
