Hey 8 Pack, good 4770k chip, let's do this!!!

Hey 8 Pack, already asked on the OC section but I thought I should get some advice from a legend

Here are my Day 1 results.

I started straight with 46 multi and 1.2 Vcore. Booted fine in Windows but I got BSOD after running AIDA64 for a few minutes, so I worked my way up to 1.26 Vcore and it was stable in AIDA64 (run a test for an hour). Temps almost never got above 70 degrees, but they spiked at some point to 81-85 across all cores. This probably happened only once or so.

Here are the only settings I changed:

multi 46
Vcore 1.26
Uncore multi 46
Uncore Voltage Auto
CPU VRIN override Extreme
BLCK Auto
Turbo Auto
C1E, C3, C6/C7 EIST all Auto
RAM XMP

Spoiler

I will do more testing today, after some reading I am mostly worried about Uncore voltage which is set to Auto and the 1:1 ratio, so I might start by changing Vring and possibly Uncore too. Maybe even manually set Vrin. What do you think?

Based on my Day 1 results, do you think I have a chip with potential? Where should I start today now that I have a general idea of what I am doing?

Thanks!

Thanks for your input!

I will try these settings tomorrow and report back! I will probably start with tweaking multi/vcore/vccin only and work on uncore as soon as I get a stable OC.

Overclock day 2 results:

I started fresh today. Here are all the settings I changed:

Multi 46
Vcore 1.245
Uncore multi 43
Uncore Vring 1.2
CPU VRIN Override LLC Extreme
CPU VRIN Override Voltage 1.85
Memory XMP
C1E, C3, C6/C7 Disabled
EIST Enabled

Run AIDA64 with the above settings but 1.24 Vcore, crashed after 80 minutes.
Run AIDA64 with the above exact settings, crashed after 4 hours 10 minutes

I thought it was going to be stable after a decent amount of hours but it wasn't. Maybe if I add 0.005v to Vcore (for a total of 1.25v) then it should be ok. Or do I have to tweak other settings/voltages?

I feel like I am pretty close to stabilizing it, just need like another day of testing.

EDIT:Sorry, forgot to mention temps, probably because they are fine lol.

I never saw them go above 74, they were averaging high 60's/low 70's, max temps were 81-83 across all cores.

Awesome, thanks!

I am just going to leave it with these settings for a couple of days, see how it performs.

At some point I would like to give it another go, set a max value of 1.35 Vcore and see how far it goes.

I have a couple questions, my temps/voltages are safe, right? And, if I get a crash, which voltage and/or setting should be the first to change?

Thanks!

After a week of hardcore tuning I think I have a stable OC now.

With my previous settings AIDA was stable for 4 hours. I run x264 and crashed in 10 seconds, so I had to start from scratch. Here's the method I used:

I started with x46, 1.2Vcore, 1.8Vrin, 35 Uncore, 1.15Vring. When x264 failed, I added 0.005Vcore and test again. If that failed too, I would add 0.001Vrin, starting from 1.8v all the way up to 2v. If that failed, add another 0.005Vcore and repeat the process.

I found my sweet spot at 1.29Vcore and 1.9Vrin. Passed x264 and then run XTU for 9 hours.

Today I did a similar process with Uncore and ended up with 43 Uncore and 1.16Vring. With these settings I run XTU for 9 hours again, no problems.

Hundreds of BSOD's and 2 formats but I think I have a stable OC now

Dunno really, apparently AIDA64 was not enough so I thought I'd give another program a try. Is it that bad? x264 is great for quick testing while tuning though, don't you agree?

Tested BF3 today as well for a couple of hours, no BSOD's and more than double the framerate from my previous [email protected]! . Hopefully that's enough to say that my OC is stable?

And something last, what do you think of my settings? Are they reasonable? Also enabled C states/EIST and power options in Windows so Vcore and multi drop while idling which is quite nice
