Core i7 Overclocking by Batch #

[CryptiK]

Thank you very much.

What type of cooling was used with those overclocks?

The 3845B259 was on water, the two 3849B040's were on air.

I just added mine to the database:

I7 920 D0
Batch: 3939B977



To get to 21x198 (4.14GHz) HT ON it needs 1.3375 in BIOS (1.3289 load, 1.3406 idle). Can't even think of 4.2GHz with this chip (without a full WC setup).

Time for a trip to microcenter for an exchange. Maybe I'll get luckier next time.

If you can find one, the 3938B020 and 3938B024 batches seem to be the best new batches I've seen results of. There's a couple in my spreadsheet (linked above) have a look.
