Adjusting performance of a G3258 on a Z87-PLUS motherboard using Linux (CENTOS 6)
Adjusting performance of a G3258 on a Z87-PLUS motherboard using Linux (CENTOS 6)
I've been trying to overclock my cpu via motherboard bios and have successfully changed the:
-Target CPU Turbo-Mode Speed: 4500MHz through the use of modifying the "Core Ratio Limit" to 45 and syncing all cores.
-and modified the "Additional Turbo Mode CPU Core Voltage" to 1.300, which I believe is increasing the cpu voltage to 1.3v.
I am following a
guide from reddit
that says this is an alright first overclock that will likely work, so I've decided to take this method instead of gradually increasing from nothing (4.5GHz and 1.3V).
When I log in and run the command "lscpu" it says that the CPU clock speed is 800MHz. This was likely because the cpu is at idle. When I stress it out using stress tools that I have found in
this tutorial
(using the command "stress -c 4") it tells me that the clock speed is 3200MHz which is the default clock speed for the G3258 CPU.
Is this a problem with the way I am measuring/stress testing the cpu? Or am I not overclocking my mobo in the correct way?
Thanks for any advice, I will hopefully be quick to answer most questions!
MBs might seem odd when it comes to saving changes. Verify your preferences were saved at 4.5 MBs. Consider trying a 3.6 GHz OC instead of 4.5 GHz, as this could resolve the issue and confirm the settings are applying properly.
p.s. My g3258 scores 4.0 at 1.2v, 4.1 isn't stable on my chip at that speed. Aim for 4.5 at 1.3V works well, though it's not a guaranteed "easy shot" with no risk.
MBs might have unusual behavior when saving configurations. It’s recommended to try a 3.6 ghz OC instead of 4.5 ghz, as this should resolve the issue and confirm that the MB settings are being applied correctly. I recently switched from 4.5GHz to 3.6GHz and noticed the BIOS saved at 4.5GHz again, but now shows 3.6GHz. The clock speed still displays 3200MHz (3201.000MHz).
