Request for Next Steps: 4770k OC

post #1 of 6
Thread Starter 
Hello Everyone!

I originally posted this on Tom's Hardware but I have also been reading and following posts here and figured I would ask the community for some guidance here as well! My purpose here is to take my CPU as far as I can. I am currently at a stable 4.5ghz @ 1.37v with max load temps around 94c as spikes but a lower average on each core when running AIDA64. The CPU itself is registering about 65c. Idle was actually only 29-32c but today it seems to have jumped almost 6c to 36c, this may be due to the fact that I moved my GPU closer to the CPU.

First things first, here is my component list as it pertains to this OC:

Intel Core i7 4770k (of course)
Asus Maximus VI Hero
16gb (2x8gb) G.SKILL TridentX 2400mhz
Corsair HX750 Power Supply
Noctua NH-D14 CPU Heatsink
Arctic MX-4 Thermal Paste

The BIOS are set to default aside from the changes below:

AI Overclock Tuner: XMP, Profile #1 (all options, IE CPU Strap and BCLK Freq, default as auto/100mhz)
CPU Core Ratio: Sync all cores, 45
CPU Cache Ratio Min/Max: 35
DRAM Frequency: 1600mhz
CPU Power Management: Speedstep Disabled
Core Voltage(Manual): 1.37v (cache is unchanged/auto at 1.078v)
System Agent Voltage(w/ 0.35v Offset): 1.224v
DRAM Voltage: 1.65v
Internal Graphics: Disabled

Everything else is at their stock, or auto, values. I had my CPU stable at 4.5ghz with only 1.35v and the ram at 2400 but it wasn't as stable as I thought so I brought my ram down to 1600 and the volts up just a tad more. I am still trying to see just how far I can get my CPU but I am truly not sure where to make the tweaks or how far I can tweak certain voltages. I tried lowering my RAM to as little as 800mhz with no luck of getting past 4.5ghz and my first venture into messing with the Strap/BCLK was horribly unsuccessful. Either way, I am here and I could really use some guidance!

If anyone could provide me with more information on how to proceed from here, it would be greatly appreciated. Helpful items would include: how far I can safely OC my core/cache/system agent voltages, how to be able to lower my core voltage, which other voltages I should still change, and how to really make the Strap/BCLK work for me.

Thanks in advance and sorry for the wall of text! Below is a link to my bios pics if they would help:

If you are at 94C then that is to hot for everyday use. Stress testing with programs like OCCT Linpack AVX 64 Bits your max core temps should not spike over 92.

Before you can go any OC higher than 4.5GHz you will need to delid your 4770K

Understood, it is hot but it is only spiked during AIDA64. Normal operation/full gaming load it's only around 65-70c with those volts. I had a lot of discussion on Tom's Hardware that resulted in more tweaking and the unfortunate realization that my core just isn't going to get above 4.5 no matter what I do. thumbsdownsmileyanim.gif

Oh well, such is the luck of the draw. Considering 1.37v is even a bit too high for a stable 4.5 I decided to drop down to 4.4 and get it as cool as I can, maybe OC my ram to make me feel better thumb.gif

A lot of people fail to realize the uncore should be separately clocked from the cpu.

Lower your cache-speed to 37x or something, dont link your cache-voltage to your cpu core voltage/frequency.

It's not, my cache has always been manually set to 35x. The cache voltage was never changed though, I think that was set to auto.

Well thats fine. Some performance gain in upping that to 4.1ish tho smile.gif if youre into that stuff.

I need like 1.25-1.28 to run 4,5ghz but I cant even get 4.6 stable at 1.34 : /


EDIT: Priming 4,55ghz at 1.3 as we speak tongue.gif
