My OVERCLOCK doesn't want to play ball!

[Femi.anstey]

Hi all,

 

As of recently my intel i7 6700k was overclocked to 4.6GHz from it's original 4.0GHz and I ran multiple tests on it before confirming it's stability, eg Real Bench, Cine-bench, Prime 95 etc...

At 100% load using a HSF on the CPU it peaked at 79 Dagrees C with a Vcore of 1.38V which is decent in my opinion. So... as I'm sure you're all asking, what's the problem then Femi?

 

After installing an additional 24GB on DDR4 Corsair Vengeance RAM @ 2133MHz to give me a total of 32GB of RAM where all the slots are used. My PC wouldn't post. I manually had to place in Each RAM stick 1 by one and wait ages for something to actually appear on my monitor and finally I managed to install all the RAM Sticks but I'd get the message Overclock fail DESPITE me knowing that my CPU was so stable. So at the moment I'm back to Default settings in the BIOS which is mildly depressing and just don't know how to overclock my PC again after this RAM Decided to fail my overclock. Any advice at all would be appreciated, All i want is my 4.6GHz back so I can render 4k Videos I this lifetime and not the next ,)

 

Motherboard - ASUS Z170 Gaming Edition

RAM - 32GB DDR4 Corsair Vengeance at 2133MHz

CPU - i7 6700k at 4.0GHz

GPU - GTX 980 Ti OC'd to 1500MHz

Power Supply - 750W

 

I pray someone knows or has any idea of why all of a sudden my OC decides to just give up and not post when I try to get it back to its OC previously.

Does it post without CPU overclocking and with RAM XMP profile enabled?

Change everything in the BIOs back to its original out of the box state, reseat all of the RAM sticks, then go in and try to Overclock and make sure you keep the RAM freq around the same of what it's supposed to if overclocking your CPU changes that for any reason.

your oc may have been sable before you put in the extra sticks but since you have put ram sticks in there will be for stress on the memory controller so it might be best to start again with your overclock. most likely will be slightly slower than your old one due to memory controller stress

Previously I could OC and it would boot and I would run stress tests and obviously if the ovltage is too low I'd get a blue screen and have to go in a tweak a few things. But as of now I've reset the bios back to defaults and my pc boots fine but when I even attempt to overclock even but 0.1GHz it'll take ages to post then tell me overclock fail enter bios by pressing F1. And I'm too scared to re-seat the RAM Sticks because my PC wouldn't even post when I first put the RAm in and only worked after I put them in 1 by 1 and ran tests afterwards to see if they're working.

 

I'm keeping the ram freq at 2133MHz and not OC'ing the ram to 2400MHz only trying to get my chip back to 4.6GHz

I think (someone feel free to correct me) that adding more sticks can make an overclock unstable. Try from the beginning again, 4.2 1.2VCore and have that as a base overclock - then go up in frequency or down in voltage if it is stable.

 

You say you are failing even at +0.1GHZ, that seems weird. Try giving it 1.38V and slowly increase frequency from 4.0 to 4.1 and so on - if it still wont budge, I would be guessing the RAM frequency/voltage is the culprit
