help overclocking 4770k on a asrock extreme9/ac mobo please

post #1 of 7
Thread Starter 
hi guys and gals,

i just got a new asrock extreme9/ac motherboard and a 4770k cpu, and was wanting to pump it to about 4.6 ghz and with my older g1 sniper 3 i was able to push 4.7 on a 3570k with ease, and managed to do this by watching a nice little youtube video that was specifically for that mobo, however i cant seem to find a guide for this board i know there are as rock guides to oc'ing however they seem to be very different layout bios and much different config settings, i dunno if this is just the z87 boards or that haswell is much more complicated to oc , but i am in need of a "overclocking 4770k on asrock ext9/ac" for dummies guide and when i mean dummies i mean dummies lol

anyone with some advice or help to offer would be greatly and kindly appreciated,

also noted the bios i have has a night sky background with little starts that light up in the background, but the guides iv seen have bios with background that are simple blue to light blue :S also the layout is much different so certain words are different new words are now shown like "adaptive" and "c-states" which the gigabyte z77 didnt use :S

please help me

Cursed.

From sins haswell guide seems like up to 4.5ghz you can leave uncore overclocking alone and just concentrate of cpu vcore and cpu multiplier. This is what I would do personally, get a good stable 4.5ghz overclock and see what voltage you need for that.

After this your gonna need to alter the uncore frequency and you can increase vring voltage to help stabilize that uncore frequency.

hey $ilent

thanks for response i thought i had already replied but apparently not,
sorry

i tried your advice but it seems a little more complicated as upping cpu freq and cpu voltage, i tried all type of different combinations of cpu freq and voltage but most times it doesn't even boot properly i have to manually reset board, there are mentions of "adaptive mode" with voltage and also many other things with the new z87 or haswell platforms, i remember ivy bridge being much much more simple and straight forwards as you mentioned and I was able to get a stable 4.8ghz @ 1.295V on the G1 sniper 3 board :S but this new board and cpu seems to me very very complicated and messy :S

please any more advice or direction towards guides? i did check out sins guide but again much different on a ASROCK board frown.gif

What I would do is go for something simple, like 4.4ghz, then start upping the vcore until you can boot properly. Is there a cpu pll overvoltage on haswell? I remember that is necessary on ivy sometimes if your struggling to boot. I would try keep that uncore clock low for now or leave it at stock, and have you touched VIN voltage?

From sins guide:

Too high of a VIN can result in added heat (and death@ close to 3v on air) while setting VIN too low can cause instability and VCore droop if the VIN is 0.1-0.2v away from the VCore. Intel recommends keeping VIN Override at least 0.4v above the VCore.

Sorry if you already know this, im just having to guess solutions here since I never dabbled with haswell overclocking. Frankly im glad I didnt, I struggled back in the days of the i7 920 aswell since that featured uncore clocking.

@ $ilent, thanks for keeping up to the thread btw smile.gif much appreciative smile.gif

well funnily enough out of all the oc threads iv been looking through i found this small page which wow has the only solution to pretty much just getting a base point this is the info i found including link

http://www.tomshardware.com/forum/id-1722630/intel-god-quick-dirty-guide-4ghz-haswell.html

thanks to the poster of this too

i managed to get a stable IBT 110 cycle standard test on these settings so i upped the vcore to 1.365v and set my core clock to 46x multiplier smile.gif and is stable so not only does this info get a stable 4.4ghz but also tweaked i got 4.6 smile.gif how ever now my concern is:

1. "CPU Cache Voltage" or Ring Bus Voltage , What does higher of this do and lower of this do?
2. "VRIN" or "CPU Input Voltage" (Fixed), What does higher of this do and lower of this do ?

Google doesn't give me simple term explanations

any advice ? please

thank you

Not sure what those voltages specifically do cursed, I would post in sin0822s haswell guide. It looks like hes put up some explanation as to what they do, but not being a haswell owner I admit I havent read that guide through fully smile.gif

yea true ye im the same here new to haswell too $ilent and not too familiar on the oc methodology on haswell as oppose to ivy bridge lol, anyhow thanks for the help if and when i come to a more better understanding ill reply with what i find smile.gif
