Gigabyte z77x up4 th & z77x up5 th Overclock/Settings Guide

Just thought id post my 4.5ghz overclock(f9 bios) screenshot settings for anyone that might be interested,they are a rough guide and nothing fancy,just a good place to startPlease feel free to post yours ect as every little counts

You missed screen shot of advanced voltage page. You have the dram section.

And is that 4c/4t or 4c/8t?

Re: Gigabyte z77x up4 th & z77x up5 th Overclock/Settings Guide

which page am i missing? though i caught them all? and yeah 4 cores 8 threads

M.I.T > Advanced Voltages. Where is shows vcore vtt and imc voltages.

Now its there. I did not see it before.

Looks like a pretty good cpu you have there. Whats core temps look like under load? Whats max it can do with HT disabled?

Re: Gigabyte z77x up4 th & z77x up5 th Overclock/Settings Guide

i havnt tried with multithreading disabled,max temp 5runs on maximum was 72c but it is winter here,right now its on a par with my 2600k temp wise,but that needed 1.36v for the same clocks,this needs 1.188v,actually the 2600k hovered around 75c

My main rig 3770K I use +.015 DVID and High LLC. My other rig 3770K I think +.005 DVID and Medium LLC. Otherwise everything else is Auto except RAM & Vtt settings.

If you want to see how stable it is you probably want to run P95 with the AVX instruction set and >90% memory used. Then if you can pass with no WHEA errors in Event Viewer you're probably OK. I ran mine >12 hours but in reality it takes around 15-18 hours to run all the fft's IIRC.
Of course some could care less.
For quick runs sometimes I just run the first two fft's, which defaults to 448K & 8K I think. The 8K will bring the heat on and either or both will pull WHEA errors if Vcore not high enough.

those are my temps with above settings,i know its not a full on stress test but its a good indicator

Re: Gigabyte z77x up4 th & z77x up5 th Overclock/Settings Guide

wazza what was your ambient when you ran that test above? max Vcore?
Looks like you got a pretty good cpu.

Re: Gigabyte z77x up4 th & z77x up5 th Overclock/Settings Guide

max vcore is 1.188v,ambient is around 25-28c not sure on that though,maybe 30c with the heating on

Damn you like it toasty warm in your house. Drop that room temp to around 20c and see what your temps look like

If your highest core temp was 73 above 25c ambient, I would say you have a really good cpu.
But I think if you run P95 with the AVX instruction set you will have a bunch of WHEA errors. Whether or not that matters to you IDK. But glad you got a good one!
Neither of my 3770K's are all that great, heat wise.

Re: Gigabyte z77x up4 th & z77x up5 th Overclock/Settings Guide

this coolers pretty good too but i had to unscrew the endcaps to fit it in the case,and i can only fit one of the 140mm fans on it due to the mounting,tension bolt sticking up too high,its taller than my d14 cooler,what sort of voltages/llc level for 4.6/4.7ghz? anything else i need to enable/disable,i tried with 4.7ghz but i think i need a big bump in voltages

i havnt had much time to mess on it yet,plus im using a really slow hdd which doesnt help

EDIT managed to get voltage down to 1.176v,

Re: Gigabyte z77x up4 th & z77x up5 th Overclock/Settings Guide

All the OC voltage is going to be dependent on your cpu, like I said the 3770K's are all over the place on vcore. The one on my UP4 is the "hot" cpu so I don't even try to clock it higher than x45. Seems like you have a really really good cpu but once you get above x46 you have to start piling on the voltage. For x47 I would use straight Vcore no DVID unless you can get enough LLC.

Are you still using the beta graphics drivers? I think I already said this but I had to uninstall them, they were wreaking havoc. I haven't tried any of the newer betas. They were super fast in benchmarks when they worked, though.
I've fiddled with Afterburner 2.25 a little, OC with two cards on my machine seems a lot harder than when I had the one 7950. Had to keep bumping the voltage until I ran out of time and stopped messing with it, and this was with just a measly 1000 core clock.
I'll get back to it later, though I'm curious what these two cards will do.
