L632BXXX, can't remember well, not in hand by now.

How many E6300 did you try?

Can't remember, but <40 pcs for sure.

Your luck is absurd. I tried about 3000 (of E6300, E6400, E6750) and found only three that would barely do 600 on air. Nowhere near 615.

That's a crazy achievement!

Well, I tried 500 pcs E2140 and found only one can do 580 LN2, but Mr. Hackeronzo only bin 42 pcs. Luck you know, just like lottery.

Nice, my best E6300 also has this Batch number. (L632B003)

Eisbaer798`s CPU Frequency score: 4493.69 mhz with a Core 2 Duo E6300 (hwbot.org)

Then i probably only have to test the CPU again with one activate core ?

This is still very lucky  I tried 1500-2000 pcs E2140, E2160, E2180 and my best chip did 565 LN2.

We all know that FSB wall is really a bi*ch, I tesed ~1000 pcs E5200 and still no go for 500 FSB

For E5x00/E7x00 you need PLL under the default 1.5V, which only Gigabyte P45 and PLL-modded boards can set.
Without PLL mod, the current #1 E5200 stops at 390 air, 480 LN2.

Also, you can immediately discard Wolfdale-3M derived ones (96-98%) and focus on Wolfdale-6M ones. You can distinguish these physically.
I've tried around 100+ of the latter, which would yield same results as 2000-4000 random ones.

Quite noob about it. Does it mean that e7xxx are based on wolfdale-3M silicon most of the time but 2-4% of these cpus may be based on wolfdale-6M? How then one can distinguish these?

I recon capacitor configuration on the back should be an easy way to tell them apart, wolfdale 6M is quite distinct.

Northwood style

I've only seen Wolfdale-6M chips on E5200 and E7200 and heard about Celeron E3200/E3300. Not sure if other models ever even existed.

I had E3200 with 6M core, but was dead

I've tried around 50 of the latter, which would yield same results as 1000++ random ones.

For me, PLL<1.5V made worse CBB first, and worse CB sometimes.

Generally speaking, E5200 from Wolfdale-6M work better than Wolfdale-3M indeed.

I got only one E3200 from Wolfdale-6M, but no OC surprise. And I have several E3300  from Wolfdale-6M, no OC surprise too.
