    Thread: RTX A6000 Benchmark OpenCL
Post: RE: RTX A6000 Benchmark OpenCL

I've compared all modes, straight wordlist, derivation rules, etc. At factory clocks A6000 is a bit slower than 3090. With non-aggressive overclocking, so they run stable and stay cool, they give pret...

Thanks Phil, I'll start digging. The algo is RACF KDFAES and I'll provide the code for hashcat once it works on both OpenCL and CUDA ... as to avoid the embarrassing moments ...

Guys, I have a custom hash module that works happily with the OpenCL API, but fails miserably with the CUDA API. Specifically, the CL compilation is ok, but the self-test fails (and indeed, it fails t...

Post: RE: Which 2080ti in a 4U?

We use several Supermicro SYS-4028GR-TRT2, each with 10x 2080 TI (Asus blower version), light overclocking, and they happily work 24/7, decent temperatures and all. Well, to be fully pedantic, we have...

Post: RE: PCI SERR with AMD but not NVIDIA

Quick update: I managed to get a stable system with a lower PowerTune value (-8, works with 6990 and 290X), with some 5-7% performance loss, always keeping an eye on the total power draw reported by t...

Different card tested, same result. Definitely something weird.

yep, could be. but the 6990 has the same performance in both systems ... only it is gen2 and not gen3. i'll go play with the bios settings, hope for some dumb luck :)
