[FS][EU] Z87/Z97 OCF only compatible 4770k


Recommended Posts

Hi all!


Testing waters with a couple hw I have absolutely no use for. First up:

1x 4770k L310B491, eBay Germany scam I "luckily" bought myself, came doa (stuck at 78 post code in several different boards), had to fight for months before getting some of my money back. Almost half a year later accidentally found out it lives on Z97 OCF with a special bios that boots 1c2t even after battery removal, or cmos clr/set defults (I supply the bios file to the possible new owner).

After some testing 3c6t works fine, pci-e working fine, IMC is crazy outstanding (at least to me, best I've had), does PSC 2736MHz waza tight with sub stock VCCSA, 2780-2800C8 R15 at stockish SA with some tinkering and good mems.


2666C8 tight, SA 50mV undervolted (0.790V HWiNFO) in Z97 OCF and also indication of a good IMC is that my mems do spi at lower volts than with most of my cpus, so instead of my usual 1.84V they pass 1.83V 2666.


Could be a good daily cpu at 4.5GHz 3c6t, or a low clock challenge 2c2t spi machine on phase, maybe a ram tester for anybody wanting something good for that only. CPU has been delidded by eBay scammero and glued back (ugly job) with LM, I didn't re-delid it, no idea what's under the IHS, Conducto or CLU.

FYI performance like this is almost always on par or a bit better than clock to clock with an i5-4670/90k in multithreaded applications like R15 or Geek3, etc.





110 euros+shipping EU only. paypal and buyer covers fees. ofc no warranty or returns apart from DOA which is unlikely, but still.

Other parts will come up as I progress in testing them for selling.


Edit: as Jason stated, there is a Z87 OCF bios too for these kinds of chips, I can provide that one too. Now the cpu works in twice as much of boards. :D

Code 78, seen that before.

Just want to point out that there is a bios for the Z87 OCF (L1.83A) as well as the Z97 OCF (1.12H) made for 1c2t dead core booting. I thought there was one for the Z87 MOCF as well but I'm not finding it rn so maybe not. Also been told that Asus had one for the Impact? if I remember correctly.
