We have Z820 worksation which have 192GB RAM and RTX2080 TI GPU on it. When I wrote below code

X values which is small (X<4000) it works. But big values PC restart itself after run the code . I set up latest nvida cuda drivers .

Would you give me advices??

        X=4000;
        tempCPU= single(rand(X,X))
        tempGPU= gpuArray(tempCPU)
        time=gputimeit(@()(tempGPU*tempGPU))

Just to clarify, for large values for X, MATLAB runs the code and then your machine reboots (i.e. restarts)? What values of X are you seeing this happen?

for example larger X values than 4000 pc restart itself

Almost always the only way the GPU can cause your PC to restart is a power supply issue. You should check that your PC's power supply is sufficient to supply the maximum power required by your GPU.
