Agh is it bad that I just want to go buy another 3770k so I have another chance at getting a better chip?

I just got one from almost the exact batch 3770K / 3237B804

Does 4.5GHz @ 1.236v stable and 4.8GHz @ 1.296v stable (both prime blend)

I did not try 4.7Ghz, though.

I can't do 4.8, my Antec can barely hold 1.24 in check.
Definitely seems like a good chip though.

Ditto. 4.7Ghz @ 1.248v is damn good. With my ambient temps I couldn't even get close to 4.7GHz on air.

Is that Prime stable?

Yes I did prime custom blend for 4 hrs and IBT on max with no errors. In the mean time I was able to drop the voltage even further to 1.20v by lowering my LLC to 4 instead of 2 and bumping my turbo voltage to .065. IBT on max so far with no errors, will do prime tomorrow and save some pics.

Interesting, it looks like 4.7Ghz is the sweet spot for this batch. I'm currently testing 4.7GHz @ 1.236v. So far 2hrs Prime stable. If it passes 8hrs I'll try a lower voltage.


Edit: Wow, what difference in voltage from 4.8 to 4.7Ghz!. 10 hrs prime stable @ 1.236v. I haven't even tried lower voltage. I'll try lower tonight after work:


Compared to what it took me for 4.8GHz:

That's a good start but 1hr of Prime isn't much. It would be great to see it do 8+ hrs of Prime custom blend with at least 80% of memory in use at that voltage. It would give me hope. biggrin.gif
