GA102-250 is ES only. It's not because there is more than one core ever that's it's retail core. The need for patched driver is the biggest clue here. Just have a look at all ES Intel CPU sold the past few years in Asia, they all are still ES despite hundreds/thousands of SKU sold.

This sample is definitively an ES sample, it have a GA102-250 core (10DE 2205 device ID) which is a known ES core, it's not something local shop are making. If it was hand made it would have been using a GA102-225 core (10DE 2208 device ID)/regular 3080 Ti core with a bios that disable a channel (not hard to find) and no driver limitation (cause it's a retail core). You're right when subbing the card in the 3080Ti 320bit category cause it correspond to this exact card. Though be careful with the card/any serial number, I heard that Nvidia doesn't like you to own this ES card.

Thanks all

Nice one with Asus P45, how high would it clock C2Q FSB ambient ?

Nice one, hopefully this chip will see LN2 some day 1.59 or 1.77 are fine, 2.00 and up are known to be troublesome for legacy HW.

I might try some day then, mostly for fun. In case it fails to post, how are you flashing back the eeprom ? any special external programmer ?

I didn't tried dual channel cause I was aiming DDR3 2000

Would it work on P4P800-E rev 1.02 ? it's slightly different from the non E variant

FYI I tried with my DDR3 2100+ 6-7-6 capable REX (using Elpida Hyper) 2Gbit Micron M-die (4GB/stick, 2200+ 7-7-7 capable) but I wasn't able to clock any higher than 1850 in single channel configuration. I guess it just hate high density IC.

Thanks !

6.4G on all core is mental, this CPU can't do it. I had to finish the session early cause of some water, I believe I could have pushed the mem at 1400 and the CPU one multiplier up, maybe tried 3 core instead of 2. Hopefully I can push tRCD 9 next time.
