I was thinking about your post about the suspected degradation. When is the last time you reinstalled windows ? it is possible your install has became somewhat corrupt due to bsod ing many many times. rolleyes.gif Maybe not likely but possible. I would rule it out at any rate though.

I think i responded to that to agree, I had noticed before a few people were just listing the 3 numbers which aren't useful as batch info, but hadn't looked at the op in a long time & didn't realize that was how they were going into the spreadsheet.
Wish I had seen that sooner, much too late now to fix it with so many posts in here though.

I'm at a bit of a loss with my 4770k.

It can easily hit 4.5 GHz stable (overnight Prime95 blend and LinX) at 1.28v vcore with 2x4 GB 2133 MHz @ 9-11-11-28 on 1.5v without breaking 75C (custom loop).

Reaching 4.7 GHz has, however, proved challenging. I upped my vcore to 1.35v and would get 9C BSODs after an hour of Prime95. Thinking my IMC was the culprit, I backed my memory off of XMP and lowered it to 1600 MHz. Still nothing! So, I dropped my cache from 42 to 35, fixed VRING at 1.2v. raised memory to 1.65v, boosted VCCIO and VCCSA +0.15v, bumped VCCIN to 2.0v (initial and eventual), disabled spread spectrum, and set LLC to level eight. No change - still "earned" a 9C after two hours of Prime95. Frustrated, I reset my BIOS, re-enabled XMP, fixed vcore to 1.375v and left everything else stock. Was able to successfully stress test overnight @ 4.7 GHz.

Am I missing something, or is it really possible for a 200 MHz bump to require a 7.5% increase in vcore? I'm not even at a temperature wall, I just don't want to run my CPU higher than 1.35v. I suppose I should be thankful that my 4770k can reach 4.5 GHz, but considering it has an idle voltage of 0.016v, I was hoping for so much more...

to my knowledge it is pretty standard to need a huge boost in voltage to get over the 4.5 hump on most if not all chips.

It's possible. I've bsoded many, many times not just from trying to jump over the voltage wall, but also from doing many tests for this thread. But that doesn't fully explain why I would pass 10 pass of x264 but struggle to pass half a pass now. A lot of Bsods I've had were before I settled on my x46 OC. If extra bsods caused it then it must have occured after I got x46 OC which is within two months. Still possible though. In that time I was trying to figure out the meaning of the bsod codes and I delibrately forced a good 20, 30, 40 Bsods in attempts to figure out what is what.

Already mentioned while back but I'll restate... That new batch numbers added will be four digits. And I will be making followup PMs to people in the chart asking them if their OC took a turn for the worse and if they can provide a better batch number value.

It's likely that most of those changes you made didn't do anything.

I would have gone 45-46-47 on core instead of jumping 200mhz with a big voltage gap (and also had cache down @33/1.15 the whole time) but RAM volts, io, sa probably didn't do anything, VRIN you should be adjusting anyway with vcore as needed, llc would have been already on (from earlier ocing)

0.1v for 200mhz at this point is pretty standard. Your chip looks quite normal to me, and quite close to mine (though mine is a bit better on vcore)

Also, if you're setting 1.375v in bios, your chip is targeting ~1.395v load. If you want to stay at 1.35v, you'd have to set ~1.33v or less, which means 4.6ghz

All of them idle that low btw, it's irrelevant for overclocking reasons biggrin.gif

The only voltage that people pay some attention to is vcore/vid with turbo boost disabled while under load at stock settings (usually a non-avx load for comparisons sake) as that can be a little indicative of chip quality (but not necessarily)

If extra bsods caused it then it must have occured after I got x46 OC which is within two months. Still possible though. In that time I was trying to figure out the meaning of the bsod codes and I delibrately forced a good 20, 30, 40 Bsods in attempts to figure out what is what.



Already mentioned while back but I'll restate... That new batch numbers added will be four digits. And I will be making followup PMs to people in the chart asking them if their OC took a turn for the worse and if they can provide a better batch number value.
you should put whole batch#
