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

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!
 
As i have said before, your uncore voltage at auto will set it at 1.4+v way to high. thats why you are able to get 1/1 4.6ghz ratio. your going to end up burning that chips life away at those voltages.

-------------------------------------

try for 4.6ghz with 4.3ghz uncore
set vring @1.260v
vrin @1.860v
vcore @1.260v
digital ao and io and systemagent voltage @0.150v

and just enjoy and use your system as you would normally if you must stress test
run memtest 2 full loops then run test 6 by its self for 5 loops and make sure you run the tests in multithreading mode
and in windows run aida32 with 1gb per thread for 30 minutes.... if fine then just use your computer as you would normally do. untill something happens as 8pack would suggest.
 
Chips are not as sensitive to high uncore as they are high Vcore voltages. That been said 1.3v Uncore should be enough for 46 Ratio or around that. I would also set VCCIN to 1.85v.

Otherwise your doing fine. Chip looks ok for sure not a gem but ok.
 
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!
 
Max volts 1.325v no point in going further on ambient. The chip will tell you when to back off. Temps who cares!!! below TJmax so fine. I hear this harped on about far too much. Just dont hammer it with Prime, IBT and all that junk.

Depends on the error or problem as to which combination of voltages to change.
 
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 :D

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]! :D. 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 :)
