5930k - 5ghz overclock problem

[the pokemon kid]

Hi Guys,

I need a bit of advice on overclocking my 5930k. I really want to get a 5ghz overclock on the processor but I just cannot get the boot up stable.

My system is currently at 4.5ghz on 1.17v on adaptive voltage.
My motherboard is the Asus Sabertooth x99 and I have 32gb of Kingston G.Skill RAM (Not overclocked yet).

The problem I am having is that the processor will not always boot up into windows at 5ghz at 1.2-1.3v. It usually fails are the balls of windows 7 are coming togethor. However, if I dont get a blue screen and the PC boots into windows then it is 24 hours stable within AIDA64.

Is there anything I can change within the BIOS to help with boot up stability?

I may be thinking of something different but is there a option for a seperate boot up voltage?

I think I remember there being something like that on the X79 platform.

Any idea what the option is? I will give it a try as the temps when I do boot in are pretty decent still...

TBH I would suggest you go with a fixed voltage instead, more stable Have you tried fiddling with the other voltages? Also Can I ask what you intend to use the 5Ghz OC for? If its just for a show or benchmark then OK, however if its for daily use, I would recommend you stick with the 4.5 you already have.

Also some just wont go to 5.0. Make that most, at least not with decent volts, even then..

This above !!!

Haswell-E does not overclock that well on water and I don't think I have seen one go to 5.0ghz yet unless it was using LN2.

The highest clockspeed I have seen on a watercooled Haswell-E CPU is one that belongs to an AMD rep (lol) I know whose 5960X can hit 4.95ghz. The odds of getting one that fast though is about 1 in 200.

I guess my next upgrade should be to order 200 about 5960X CPUs

The 5ghz overclock is a fixed overclock, I wouldn't be attempting it on adaptive voltage. The 4.5ghz overclock was found using fixed voltages at 1.16v and then cranked up a little notch and changed to adaptive voltage (1.17v).

The 5ghz is to just benching the chip. I wouldnt have it 24/7. I think I would be pushing things a little much!

I am just surprised that an extra 0.13v wont allow me to get the addition 500mhz on the processor...

I think you need to do some reading on overclocking Haswell-E as some of the figures you are quoting are very strange.

It is pointless trying to give you figures to use as no two CPUs are the same.

Once you have read a good guide on Haswell-E overclocking you will understand why some of your quoted figures are strange.

 

[Thelosouvlakia]

Try going into windows on stock settings opening msconfig and selecting the diagnostiscs boot that doesn't load anything except the very basics. Then restart, go to bios load the OC profile and boot!

I followed Linus's Haswell-E overclocking guide he posted up. I started at fixed 4.5ghz @ 1.3v and worked my way all the way down to fixed 4.5ghz @ 1.16v where it became unstable at about the 12 hour mark. I then changed to adaptive voltage and put the maximum to be 1.18v where it had been 24 hours stable. I think that the line between stable and unstable must be around 1.165v.

The values in the BIOS as as follows

CPU Core ratio: Sync all cores
Multiplier: 45
DRAM Frequency: 2400mhz
CPU Core Voltage: Adaptive Mode
CPU Core Voltage Offset: 0.001
Additional turbo mode CPU Core Voltage: 1.18v
Total Adaptive CPU core voltage: 1.181v

Everything else is set to auto currently.

You should have stayed @1.3v fixed and pushed the clockspeed up to see how high you could get.

You mentioned you wanted to overclock for benching earlier, if this is the case only use fixed CPU voltage as it is more reliable and you can use lower values.

The other thing to remember about benching is it does not have to be stable for 12 hours, 12 minutes will normally be enough.

That is exactly what I am doing, I haven't yet said that I am using adaptive voltage to overclock to 5ghz.

I have got a 24 hours stable, 4.5ghz overclock @ 1.17v on fixed and 1.18v on adaptive. This is what I use for 24/7 use and have dialled it in instead of just leaving it at 1.2-1.3v where it would be easily stable.

The main thing I am perplexed by is that I am doing 1.3v and just cannot get 5ghz. I am just surprised is all because the processors 4.5ghz are pretty low voltages! I will try and build my way up to it, however the issue I was having was the boot up part was the unstable part. It was getting 24 hours stable when I could get into windows and run AIDA64 at 5ghz @ 1.3v.

The main issue has been that I was only able to boot in a few times and haven't been able to since.

If you are really only going to use a high CPU clockspeed for benching it is a bit of a waste trying to get it stable 24/7 as all you are doing is thrashing the CPU into the ground.

For normal use I only run my CPUs @4.0ghz and that is plenty for things like gaming.

It is only worth getting a PC stable 24/7 for the speed you are going to use 24/7.

Another problem with some of the software that people use to get stable 24/7 is it does not always work. When you use a PC for gaming it can often be more demanding as the GPUs and other components are producing heat that is not present with things like prime95.

I ran it at 5ghz and for 24 hours to prove that the CPU was capable of doing it and that there is an issue with the boot up voltages. However, if I ever want to run it at 5ghz again I need a work around for this bootup issue.

4.5ghz is a spot where I am happy to run 24/7. Especially with how little voltage is needed to achieve it and all the temps being bellow 70C on each core. This is also the reason I am using adaptive voltage as the processor currently (Pretty much idle) is using 0.779v to get 1.2ghz.

To make sure everything is 100% on an overclock, I run AIDA64, all the tests of passmark and then Valley or Heaven Benchmarks. A test which I have ran a few times is rendering out a video via Premiere Pro. I have got a friends music video which I used as a test when I was checking the stats between stock clock and overclocked performances for output rendering.

Heaven and Valley hardly touch the CPU at all. If you want to torture it run Asus Realbench.

I run them more to check to see if there is any impact on the GPU performance. If the overclock effects the valley/ heaven scores negatively then it fails the test in my eyes.

Remember that your chip will have a limit, no amount of voltage will take it further without doing damage. Secondly, if you find that limit, it will unlikely last. As you stress the CPU, it will effectively start to degrade the internals. Just because it hit one speed a few times, does not mean it will still hit that speed next time you reach for it. You have to also accept that there will be a major spike in voltage needed when you go past the "sweet spot". My 4670K will do 4.5 @ 1.195v, 4.6 requires 1.29v. Just pointless reducing the life of the chip for such little performance gain.
