Problems with 6700k overclock.

[Chrispottsov1987]

Put simply, got a nice boost at 4.6ghz Wont push any further til I get my h2o working, Need a new mounting bracket, Misplaced my old one.

 

SImple problem is this, When I run any benchmark, the cpu always throttles back to 4ghz. Now through temp, as they are always sub 60c 

Now correct me if im wrong, but an overclocked cpu should mean adjusting the minimum speed of the cpu, not the max.

 

After all I can put a clock speed of 20ghz but if its always dropping back to default during any workload then its not an overclock. Just some troll button asking "What do you want CPUz to tell you?".

 

Need some help with this, I dont want a 6ghz max speed, but I do want a 4.5ghz\ish min speed. Also voltage is 1.36 anything higher my mobo starts to argue about overvolting. Though it seems to be a fair avg, that this chip can handle upto 1.4volt without any issues. Any advice would be good. 

 

Best give some specs.

OC set to per core or all sync'd?

[Chrispottsov1987]

Set to all, dont see the point in only doing per core.

[Big-G]

Per core allows for setting higher OC for single core usage than all-cores where the whole holds back the possibility of a single core to be utilized even higher

 

Did you up the core voltage?

[Chrispottsov1987]

upto 1.36 was at 1.23ish before, was waiting for some instability to show before I messed with it further. But cpu is dropping down the multiplier when ever I run a benchmark, so im not testing an overclock, Might try to set per core, and do each to 4.6ghz see if that offers any better results, But first I got to get the cpu to do what im telling it. 

 

What good is an overclock if the cpu decides to ignore it, and do its own thing.

[Big-G]

Per core works on a descending speed config:

1 core @ 4.7

2 cores @ 4.6

3/4 cores @ 4.4

 

Not sure then, might need to set everything to stock and troubleshoot by introducing only one change at a time.

Could you possibly take a picture of your BIOS and show us what you changed?

 

If you plug in a USB flash drive, and hit F12 in your BIOS, it should prompt you to save the screenshot in the USB drive.

If you could take a few pictures of the BIOS, I can tell you what needs to be changed.

[Chrispottsov1987]

Yeah, might take some more testing. Just new to intel chips, was wondering if this was a common thing with this chip. Missed a setting in bios or something, windows powers option is to always run for performance, max cpu speed, c state and rest disabled. 

 

Hoping someone on here has tried to do with same cpu. Linus has a Overclock vid up, sadly he speeds through the testing phase, so I was not able to check if his rig was down-clocking during tests. 

 

Will try to get a screen shot of bios for you, got to reset, be back online in 10-20 mins max.

[Chrispottsov1987]

Could not take screen shot from bios so had to use phone, sorry for poor quality but im on a prokector screen.

 

Multiplier set to 46, Core speed 100mhz

Voltage 1.36

Cores set to individual,

xmp profile running.

 

For some reason cpu reads 4.2 during  bios.

 

First pics, show before and during Aida test. 4.6ghz before running test, 4.0 - 4.1 during from taskmanager, Using cpuz the core speed was all over the place, Wildly swinging from 4.6 to 3.7ghz. Temps are only just hitting 60c, Slightly higher than last test, no doubt due to fact I have heating on.

Interesting development, When I run CPU stress in Aida64 thing is rock steady at 4.6ghz, However with FPU the cores are stuck at 3.8ghz. Was running both at same time. Looks like that was the goof, Not used to Aida, norm use prime95 but the 6700k is a pain to get readings from, Prime, and openhardwaremonitor will not show voltage or temps. So ran Aida on linus reccomendation, from overclock vid. Dont think Im meant to run both at once. 

 

So this looks stable now, Though anything using FPU is killing it, 

 

Think im going to run this on a much longer benchmark now make sure this is truly stable. Sorry for posting this topic, Seems it was an error on my part. 

 

Thanks for the help.

 

Feel free to comment if you still have any suggestions, but given the large number of threads already on this chip, it seems silly to open another just for OC's, since the original reason for this topic is now mute. Might be better to let the post die off, before I get the inevitable "Use Search" reply for OC's on this cpu.
