Is there a good i7 3770K batch number? - Page 41

post #401 of 407
There is a guy on hardforum selling a 'silver 3770k" that is delidded and can hit 5ghz 1.4v, so sounds probably stable at 4.8ghz under 1.34v.
If I didn't already have my delidded 3770k (4.8ghz delidded CLP Prime 27.7 AVX stable less than 1.3v) I'd be over that for a lower price.

Prime 27.7 AVX tests on the verge of stability, if you don't believe me fire up BF3 and see what happens within 3 - 4 hrs or so. You will need about +0.03v more vcore to be completely stable

Yes, Costa Rica.

I've got a Costa Rica 3770k (don't remember batch number) that's been at 4.7GHz 1.3vCore and SpeedStep and LLC and all that power saving mumbo jumbo since launch. I've done 12 hours of Prime95, Intel Burn Test, countless encodes with Handbrake, Adobe Media Encoder, endless hours of games, etc. etc. etc. and it's been stable as can be.

PS
It'll do 5GHz under 1.4v.

PPS
I haven't delidded.

4.7 at 1.3, and 5.0 at < 1.4 ?

You must have an ASRock extreme series board. Get a DMM and talk to us about voltage.

I will just leave this here:

P.S. My chip does 5.0 under 1.35 on an ASrock extreme series.

This problem was noted a really long time ago. Am still surprised no fix for it has been released to date. That's just a strike off on all Asrock boards for me.

Bit late to the party..

This is the best image I have for now. Might even go lower but will need to rebuild before I can test.

Batch # 3218C109

Costa Rica batch 18, 29 and 30 are 'golden' ones if this hasn't already been posted.
