    Thread: Bare Metal stability vs PCIe passthrough
Post: RE: Bare Metal stability vs PCIe passthrough

That's a good point. I haven't personally seen the instabilities at all, so I'm challenging the suggestion that everyone who uses hashcat see instabilities and is just used to it.

Post: Bare Metal stability vs PCIe passthrough

Help settle a discussion for me.  On our server, we've tested out setting up a VM with QEMU/KVM and using Virt Manager to pass GPUs to it. So hashcat is running in the VM and the bare metal OS doesn't...

Perfect. Thanks Royce!   And love that response to Paul Moore. He's trolled some of our blog posts in the past & it's always nice to see him shut down. ;-)

  Question Thread: 8 GPUs vs two 4 GPUs with hashtopolis
Post: 8 GPUs vs two 4 GPUs with hashtopolis

Years ago I built a system with 4 GTX 980s that's been great. Looking to upgrade a bit and it looks like we can build an 8 GPU box for roughly twice the cost as a 4 GPU system. Is hashtopolis stable e...

  Question Thread: UPS/surge protector
Post: UPS/surge protector

I'm curious if anyone uses a surge protector or battery backup for larger cracking servers. Our system has four 980s and it's fine when not cracking, but as soon as we spin up the GPUs it pulls too mu...

Post: RE: Fan Control

The vast majority of the sound is coming from the chassis fans though. If I go in the bios & turn the fans down manually, it's reasonable. I'd like to drop those down so they only spin up to full thr...

Post: Fan Control

I've got an ASRock Z170 OC Formula board that works alright with 4 GTX 980s. I've beefed up several of the chassis fans that handle the cooling ok, but now they're quite loud.  I'd like to be able to ...

Thanks for the advice. I've never had a system that could run hashcat well enough to offset the speed of tables for some hash types. So here's my updated build for future reference: Case: CHENB...

I've read just about every build suggestion on here & have several pages of notes, but this is my first build so I'm still a bit anxious about it. I'm hoping someone with experience can look over what...
