Trouble with 4790k

post #1 of 16
Thread Starter 
So I got my 4790k and have been playing with it for a few days now and I cannot get this thing to go above 4600ghz. I tried a few different things but it just seems this chip does not like anything above 4600ghz. Im not the best with overclocking but I can follow directions on what I should do/try. Does anything have any suggestions on what I can do? I would like to start over, I just changed everything to default in the bios.

Here's a guide for Asus Z97 motherboards for overclocking 4790K. Similar when overclocking an old Haswell cpus.

Can you list your overclock settings in this order?

CPU multiplier?
CPU voltage (aka vcore)?
CPU cache mutliplier (uncore)?
CPU cache voltage (uncore voltage)?
RAM speed?
RAM voltage?
Eventual Input voltage? (VCCIN)?

Right now I really don't have a set OC in place since everything keeps failing. I just have XMP set and have the multiplier at 46.

So everything is in auto settings? You should set them manually bro.

Turn off XMP and set them manually, it's really hard to get stable when you overclock cpu and memory at the same time.

Here's a template for you to start:

CPU multiplier = 45
CPU voltage (aka vcore) = 1.250V, manual
CPU cache mutliplier (uncore) = 35
CPU cache voltage (uncore voltage) = 1.15V, manual
RAM speed = Stock (1333 MHz)
RAM voltage = 1.5V
Eventual Input voltage? (VCCIN) = 1.900V

Disable C States.

Ok thanks a bunch Ill try that. Should I go 1600 for the ram I think that is stock?

Ok set everything to what you said the ram is at 1333 as well. Do I just keep increases the multiplier and go until it crashes then increase voltage?

If your ram is stock 1866 you should be able to set it directly to that mutli. Then yes, increase cpu mutli until it crashes, increase voltage, repeat until temps/vcore are somewhere you don't want them thumb.gif

Ok thanks. What is too high of a voltage for the 4970k? This is the best ive done so far with this chip, Im at 4700 @1.35v. Ran prime for a while and its stable. It reached 68 C during it which I don't think is too high.
