How to tell if a 920/930 has OC potential?

post #1 of 5
Thread Starter 
Is there a quick and dirty way to tell if a chip has good OC potential. I'm thinking about just buying a few chips and sorting them by whatever parameter that is and tweaking the best candidates. Is there a way to tell right away?

Umh...not really, best you can do is matching the batch number with other users but even that still doesn't guarantee it's gonna be a good clocker since each chip is different. If you get lucky you can get a cherry-picked CPU but if not then, well you know

I imagine it'd be from their batch numbers. There's a thread here somewhere with all the batch numbers in there and how far they can OC.

Edit: it's right underneath this thread. lol That should give you a start as to which batch has better potential for OC'ing.

attempt a rush overclock. Or 'diry' overclock. Where you take the settings from a decent chip and try them against your new ones. Thats the only quick way to determine general overclock potential. As every chip is going to be different.

The batch number is on the box top, along with the S-spec.. You want a d0 for overclocking the 920. SLBEJ is d0. The batch numbers read like this:

1st letter or digit = plant code
0 = San Jose, Costa Rica
1 = Cavite, Philippines
3 = .............., Costa Rica
6 = Chandler, Arizona
7 = .........., Philippines
8 = Leixlip, Ireland
9 = Penang, Malaysia
L = ............, Malaysia
Q = ..........., Malaysia
R = Manila, Philippines
Y = Leixlip, Ireland

2nd digit = Year of production

3rd & 4th digits = week

5th - 8th digits= lot number

10th - 13th digits = serialization code
