Will stable OC system under Windows work on Linux?

[sbakic]

Hi there,

 

There is my blog about my first overclocking. So there is no doubt this is stable system.

 

Question is whether this system will be stable on linux, or should I test everything again and do the all process again on linux? I am planing to use Ubuntu 17.04 and +.

Yes if it is stable under Windows you shouldn't worry about Linux not being stable.

Yes, I have occasional freezes in linux, but that could be down to something else... they are very rare, but do happen. For the most part an OC'ed CPU shouldn't give you any trouble in linux from my experience, whether you're actually benefiting from that OC is another matter, depends on what you are doing with it. Not an expert on linux I might add, so it's from my limited experience.

Thanks for the answers.

 

I am thinking like, overclocking PC is on transistor level, which means custom CPU and RAM need certain voltage to operate at full load, and in this case OS is irrelevant. OS just said to CPU: "Hey I need you to run at full load", and then motherboard said: "Ok I have settings in bios by which I can give certain voltage to CPU" and that's it. If voltage is too low motherboard will say: "CPU doesn't have enough power(voltage) to do the job, lets shut it down".

But if difference between OCed systems will different between OS (Windows or Linux). For example,wWe OCed in one of the OS and we tested CPU and we saw 80% usage of CPU and we said "It is ok". But under other OS CPU usaged is 100% and it crashed because CPU didn't have enough voltage, because we previously thought it was stable.

What do you think about this? If first assumption is correct than aswer to my question would be "Yes", if it isn't I should do further testing.

Guys do you have any previous experience on this or these are yo  assumptions or you read/heard it somewhere?

I ran my 4790K at 4.5GHz even up to 4.6GHz.

It was stable in Windows 10/8.1 and Xubuntu.

While what you say makes me think you talk about the kernel, but I'm pretty sure it'll be fine for Linux (any distro for that matter)

I'm telling you this from experience and actually wondering about it myself and trying it out.

For me it was stable and smooth as butter, your knowledge might vary.

Agree, I've actually had many systems running OC in linux distros and windows fine, my i7 6700K was running 4.7Ghz, my ryzen 1700 one is running 3.75, but that's only because my cooling isn't good enough to go further. had an i5 4670K running 4.5, an AMD phenom II 1055T running OCed too, not by much I might add as it was Bclk OC and the board was shit, lol... there should be no discernable difference between running on linux/windows, I just meant that they handle it differently is all... you can run really old systems on newer linux builds and they will still be pretty great performance wise, not so with windows.... again just my experience of them.

@Sfekke @Strike105X @paddy-stone Guys I am new to linux  and so OCing under linux. I am using Ubuntu for a week and I am trying to test system stability under linux with mprime95. In first two tries it failed after 1.5h, after that 2h. I tried to install lm-sensors, but i couldn't i go weird results (I got CPU temp but wrong Vcore). Do you have any advice what to do? What tools you use when you are overclocking CPU and RAM under linux?

 

Do I need to install some additional drivers or something, before test?

 

P.S. I updated UEFI to 1701 version, tested everything under Windows10 with exception for prime95 stress-test. What went wrong there is I tried to run stress-test for the first time and it failed after an hour, after that I run it again and it run for like 3-4h before I stopped it (so no error). So only that first time it failed don't know why. After that I installed Ubuntu. I am talking about this because on BIOS 1501, 1601 prime95 (under Windows) didn't fail first time when i run that stress-test. On BIOS 1601 stress-test run fo 22h after fail, it run same operations for 3 times, so it needs like 7-8hours to run full stress-test for prime95. And all voltage (Vcore, Vdrop) was the same at every UEFI version (under Windows because I could see exact vlotages). Shouldn't I let all 8 hours on 1701 under Windows, maybe it isn't stable under Windows10 because I tested only 3-4h and now I am failing on Ubuntu because of that?
