I realised somehow the BIOS firmware was broken. I went into the EZ mode, and all the text was missing. I reflashed my bios and it was all good. And I saved my OC profile for 46 when it was stable with the vcore at 1.415. I challenged 47, but never succeeded.

I will use it at 46 before I get a good OCable one, probably go for the 3570K as it costs about the same as the i7 RRP. But I needed the OC performance more than anything, more than L3 cache or HT (I turned my HT off anyway).

So this is what happened. At last, I got it stable at 4.6GHz pumping 1.38V. Stressed it for 12 hours or so and seemed fine. The temp stayed below 80C too.

Though I would prefer it to go higher, I tried to take it up one more to 47. Vcore at 1.48V was still unstable, BSOD still gave me code 124 or 101. So I now have it back to 46 at the said vcore; with ram at 2400MHz 9-11-11-31 1.65v stable.

Will wait for my new 3570K to come and hope to get it better, as it is guaranteed to be below 1.13V at 4.5GHz (tested before purchase).

This is insane, how was the testing done? 4.5ghz@1.13v is crazy good.

They physically tested it. Taken it out of the box, they tell you what equipment it was used, how they OC'd it to do the test, and the exact numbers it got. Then of course, you get what you paid for, and not like just buying a random CPU and hope that the silicon will be on your favour. Sometimes you get lucky, but for me, that never happened.

I also got 4.6GHz at only 1.176V on my 3570K but 5GHz already requires ~1.44V to be stable.

Getting another 3570K today maybe so I can test which one is better and then delid the better one.

Still that's pretty decent! I can run 1.5v at 80~85C, so let's hope I can do better at 5GHz with my cooler. Still have 2 tricks up my sleeve, got an extra bank of fans for push pull, and delidding!
