Overclocked my i7 3770K with underclocking memory

Hi All

Just started overclocking a few weeks now, and been busy with it all day long,
Now i found allot of information lately, I'm still wondering if it is okay if i under clock my memory to 800 MHz? on xmp 100:133 and add 102.4 to my cpu FSB to reach 4300.7 MHz stable
If i do it like this i have much better CPU temps and i can reach 4300.7 MHz easily with my h80i cooler and it run's very fine
Will this make it slower then on normal 1333 ? ( will this make any sense? )

Please look at the picture's below
I make all settings in the bios, not in turbo V evo like show on the picture's
Real temp is running and package core went to 90c for a few seconds, this is on custom stress testing with more then 90% ram used in the latest version of prime97 25.8

Because my cpu get hotter if i dont, is there any other solution i can use to have my cpu less hotter without underclocking my mem?

 

Not overclock your CPU? :teehee:

 

You could always lower voltages and the overclock.

Lower voltages wont let me run stable prime95

Then lower the overclock, not every chip can overclock well.

4.0GHz or 4.3GHZ won't have any real time performance in gaming, nor regular use of the computer.

It is more swag, if anything.

 

What i do suspect though is that you need to re-seat the cpu cooler and re-apply the thermal paste, maybe you used too much and it is hindering you in temps.

Intel's TIM on Ivy Bridge, Haswell, and Devil's Canyon CPU's are pretty poor, although Devil's Canyon TIM is slightly better. They used to be soldered, so the heat transfer to the IHS was much better. Your temperatures aren't going to get better without delidding and putting better TIM on there with higher voltages.

Thanks for your reply

 

Already did this before starting overclocking,

will check if did not put to much between cpu and cooler

Oh, very great im happy

i did the IHS removal before, i forget to properly remove the black glue, reopened my CPU, put again new MX-4 thermal on it,
Also placed my h80i a little bit higher on the cpu, also placed there a new solid drop of MX-4 thermal between cpu and cooler, and now my temps stay under 80c all the time for each core, wihtout underclocking my memory :) on 4.3 ghz

Nice work! What cooler are you using, btw?
