BIOSTAR Z590GTA Motherboard Review


Overclocking on the Z590 platform is pretty much the same as what we saw on Z490. You will notice, at least with the Core i9-11900K that you are not going to be able to get a whole lot more out of these chips. I decided to do all of my overclocking using the Intel Extreme Tuning Utility. First we run the Intel Speed Optimizer, which is basically like an instant overclocking tool. It puts our all-core frequency at 5.0 GHz.

Running the built-in stress test I could see that the CPU was throttling because of the Current/EDP limit.

We rectify this we need to go into the BIOS. Once in the BIOS head over to the “Tweaker” tab and go into “CPU Power Management”. Once here enable both Power Limit 1 and Power Limit 2. Set their values to 409500. You are also going to want to go down and set the TjMax offset to 10 to not get any thermal throttling errors.

Running the test again at 5.0 GHz it did pass, but temperatures were extremely hot as you can see. I would not recommend this at all for a 24/7 overclock.
