Which abit slocket revision is unstable for overclocking?

[gmlasam]

I have three slockets. Two that are revison 1.0 with the plastic handle, and one that is revision 1.1 with a metal handle. I will be installing a celeron 600 to hopfully overclock at least 900, but I'm not sure which slocket with what revsion I should use.

Any input?
