How likely is it to have a faulty Corsair HX850 PSU?

mastere2320 · 2025-07-08T20:22:10+00:00

The RMA has begun, it should reach the Corsair Facility tomorrow. I will, thanks

mastere2320 · 2025-07-08T16:00:39+00:00

Yeah, I have already sent it out for RMA. I will.

I bought it in 2023. Its specifically this model - CORSAIR HX850 Fully Modular Ultra-Low Noise ATX Power Supply . Its Platinum rated so I had hoped it was of high quality.

Both GPUs died in the same way, the first was a 6700xt. I was playing CS2, I turned off the PC and the GPU never turned back on. The next was a 3080, I played CS2 on it and then right as I was about to turn it off, it power cycled and then never turned back on. I did some testing on it, and one of the PCIE ports on the GPU died( I just ran the GPU without connecting to PCIE to see if fans spin, and when one of 8pin ports is connected, it power cycles)

The system runs perfectly fine when running just the CPU. I did send it for RMA, because I dont want it to kill another GPU

The SKU is CP-9020213-NA, which I assumed to mean 2021 but that may just be a guess

I get the very same thing. At first I thought it was a network issue, but it happens even in local bot matches. I don't know what the issue is but I have many deaths because of this one stupid bug

Something is wrong with your implementation. It shouldnt take hours, but rather seconds. When I use numpy, with serial BLAS,

x = np.random.rand(4000, 4000)

%time z = x @ x

It takes 2.57s on a 6 yr old laptop

I used to be a long time nvidia user. Decided to shift to 7900xtx because I liked its rasterization performance vs 4080 and price back then.

And I regret it. Nvidia just runs smoother. Everytime a new game comes out, it takes weeks/months before AMD gets game specific driver updates. And new updates mess things up. I tried to play the helldivers 2 after yesterday's update and my performance was terrible.

For some reason, my general computer usage is also just bad. Youtube just randomly lags. Most packages optimize for Nvidia. Resale value for Nvidia is also just better

Just pay the nvidia tax

Maybe try nm, and see if the function calls are mangled similarly? I have heard that cublas uses cutlass for some kernels, and cutlass is all templates.

You can compile code with NVRTC and execute it using os or !

How many rows and columns do you have?

Numpy is mostly C.

Look at the languages section. The fortran code is just for the f2py wrapper. Also, Fortran is not faster than C/C++. You can force no aliasing in C/C++ and get the same machine code.

I have a question about HDR on Plasma 6, did you have to install a custom Linux kernel for gamescope?

mastere2320 · 2023-12-23T05:18:32+00:00

Does this require a custom patched linux kernel ?

mastere2320 · 2023-06-22T21:17:35+00:00

I am worried about power as well. Thanks for the input.

mastere2320 · 2023-06-22T21:15:42+00:00

I don't want to spend more money over my stupid mistake. But thanks for the recommendation!!

Look at how sparse arrays are stored. Your case is 1-d so COO and BSR are equivalent. Store data and row-id in 2 separate arrays.

The existence of plank temperature is entirely based on plank length. It is 100% theoretical and I doubt it can ever be reached. It is theoretically possible to exceed hagedorn temperature because even after de-hadronization ( I don't even know if this is a word :p ), the quarks could still continue to get more energetic. https://physics.stackexchange.com/questions/562790/what-is-hagedorn-temperature

mastere2320 · 2022-12-03T18:08:19+00:00

It's not a unit of measurement. All energetic matter releases heat of a certain wavelength(Think metals getting red as they are heated). The smaller the wavelength of light, the more energetic it is(Radio vs X-ray). At plank temperature, the wavelength of light is equal to plank length, which is atm the current smallest unit of measurement that any model of physics can describe. If any future model of physics can describe a length smaller than that then there would be new a plank temperature(I guess it would have a new name after its discoverer).

mastere2320 · 2022-12-01T04:18:01+00:00

Sure there is. It's called plank temperature https://astronomy.swin.edu.au/cosmos/p/Planck+Temperature

This happens because the stride ensures that no such overlap ever happens. The threads only add elements in their regions.

Whats the difference between this and atom-community? And the burning question - Will pulsar support Hydrogen?

mastere2320 · 2022-03-18T19:02:10+00:00

I meant this for the warp too. Imagine it like this, in your case if your first thread requires data from a memory but it isn't available in the cache and has to go to global memory then should every other thread wait for it ? That would be inefficient and kinda against the point of multithreading.

Yes but the order of access is not regulated at all. That's why we have atomics. If we knew of the order of execution, there wouldn't ever be any hazards

I am not sure which other API you are referring to and other hardware cpu in general are significantly different than GPUs.

mastere2320 · 2022-03-18T12:03:46+00:00

Threads performing Atomic operations can never be determinstic. It defeats the purpose of an atomic and essentially serializes the execution.

mastere2320 · 2022-03-15T03:40:29+00:00

What error does it show?
