Mining Both SHA-256 & Scrypt on a single GPU

[Crypto Elysium]

Hi, very first post.

I understand that SHA-256 uses the core clock of a card and Scrypt uses the cards memory.

So I was wondering if it's possible to mine both scrypt and SHA-256 algorithms on a single graphics card at the same time without worrying about frying the hardware.

Appreciate any feedback.

Cheers.

No, No, No, No, No. Mining in general is hot. turn your memory up mining BTC and watch your hashrate drop and heat rise.

Okay.
Thanks for the feedback.

I'll stick to scrypt.

That is incorrect.  Both use the "compute" portion of GPU it just happens that Scrypt has higher memory requirements.  Just the memory of a GPU will compute exactly nothing.  You can't mine both at the same time on the same hardware.  Scrypt doesn't even use the GPU "main memory" it uses about 128KB (that right less than 1MB) of cache found on the GPU chip itself.

Thank you.

That's cleared up a lot of confusion.

The only information I could find on the subject was this, from someone who asked a similar question.


"Rationale: Hashrate of scrypt mining is limited by memory bandwidth. That means that some of the processor cycles are wasted because the processors are waiting data from RAM. These wasted processor cycles could be used insted for sha256 mining which needs much less bandwidth."
