Avoid 6600 - Batch 7638A742

[fhpchris]

you got a couple of decent clocking chips, don't delude yourself that you have special o/c talents.

btw my 27B E6600 does 3.75 orthos stable with 1.4v (droop to 1.34 on evga 680i)...better than the avg Xeon result i've seen posted here.

I think I have had what now?

L624A E66
S6 E67 ES
L628A E66
L629A Xeon
L631A X68
L628B Xeon
L628B Xeon #2



The worst one was the 24A, and it primed 3650 or so, followed by the 28A, and each xeon has done 3.9ghz prime and the X6800 only did 3.8 prime, but it ran 3d over 4100...

I guess all my chips are not half bad... for all Retail CPUS (E67 ES and X6800 were untested used.)

clocking intels is a piece of cake, the chip can either do it or it can't.

This just isnt true, once you have a board that can do good fsb(~450+ on 9x) and give stable voltages, you run into the problem of cooling (small temperature changes help alot..L629A Xeon got 80+ mhz prime from temps) along with a nice mount, and then finally you have to deal with your system memmory and dividers...

That isn't easy.

Some chips like my X6800 do hit that hard wall, they prime 3810 or so, but 3830 just is a clear NO GO even with more voltage and better cooling by a huge ammount, but others like my L629A Xeon will just keep going and going...
