GPU overclock problem (Asus video cards)

[Lester23]

Hello recently I bought a RX 460 4GB Asus ROG STRIX OC, and I downloaded the GPU TWEAK II from Asus.

As you know, there are 3 profiles : OC, Gaming and Silent mode. I run on Gaming mode most of the times. But when I use to play some demanding games, my PC crashes*. I believe it's from OC, any idea how much I should lower the GPU Clock ?

I have 1236 Mhz, I want to lower a bit because my PC crashes for a reason

*- In middle of gaming, the game freezes and my pc restarts (I use win 10 64 bit) all drivers up to date, good temps.

it's possible your clock speeds are fine and it's your PSU causing the issue. what model PSU do you run?

matx 450w model, doesn't have a proper name/mark (Says only Made in China)

A no name PSU made in china? Makes me think even more you have a low budget PSU which can have trouble maintaining the proper voltages and amps your components need to get causing instability, crashes and even component failure. If it were me I would replace that PSU immediately. Your PSU is the last thing you want to cut corners on as it can fry your whole rig. I encourage you to get a tier 1 PSU good for 5 years approx. or get a tier 2 if you don't mind replacing it every 3 years.
