4 card cracking Rigg - JaneTheCracker - 06-01-2018
Hello Fellow Crackers
I am planning on building a new hashcat rig with a budget of 3000 euros.
I made the following graph based on the actual prices:
ntlm MH/s Price price/ntlm amount total ntlm Total gpu cost
1080ti 52715.6 800 0.015175773 2 105431.2 1600
1080 41354.8 580 0.014024974 4 165419.2 2320
1070ti 39107.7 495 0.012657354 4 156430.8 1980
1070 29890.8 470 0.015723902 4 119563.2 1880
I currently have the following rig:
- i7 3770
- 32gb 1333mhz ram
- P8Z77-M PRO (mATX)
- 2x gtx 760 fe
- 1600 watt psu
i5 8400 183,-
Corsair vengeance 32GB 1600mhz 311,-
Asus ROG Maximus X Apex 311,-
4x 1070ti 1980,-
for a total of 2781,-
I still have a couple of questions:
- Does the CPU matter for hashcat?
- Does the amount of ram matter for hashcat?
- Does the speed of the ram matter for hashcat?

Why are you upgrading CPU+MB?

I am upgrading the cpu and mobo because the current one only has 2 pcie slots. and the 4 cards are faster then the 2. I am building in a large tower so idealy I wouldn't want to use rizers.
One more question, does the speed of the ssd where the wordlists are stored matter?
RE: 4 card cracking Rigg - undeath - 06-01-2018
Drive speed only matters in so far as that it influences start time. Once hashcat is running it doesn't (unless you run a straight wordlist attack on a fast hash, but that's inefficient anyway).

IMO, hardware beef correlates with interest/focus on password cracking.
If you just want to improve general cracking throughput, you'll be fine following everything that undeath says. Most of the non-GPU-speed factors don't matter. The RAM=VRAM thing is good.
But as you start getting more focused on cracking, you'ill want more CPU (for processing wordlists, or using tools that generate password candidates and pipe them into hashcat; one core per GPU also good there), more RAM (for faster sorting/sifting of large wordlists/cracks/output/inputs; the RAM=VRAM thing is probably a fine match there anyway) and more and faster disk (same reason as RAM; useful to have both medium-sized SSD for processing data, and a large HDD for storage of large data).
Also, I was telling people PCI-E x4 is the minimum, but I was told recently by evilmog that eventually, you hit some bottlenecks that make x8 the sweet spot. But you have to go quite a ways down the cracking rabbit hole before you get there, I think.
If you think you might get into it more, you can at least make sure that you have an upgrade path -- getting a board that's capable of a faster CPU, more RAM, etc. That way, you can save money on the other stuff until you get the point that you want more - and then you'll know better what else you need.

Do you mean that if you have 4 cards of 8GB RAM each, one must have 32GB RAM (on MB) ?
RE: 4 card cracking Rigg - undeath - 06-03-2018
That's correct.
RE: 4 card cracking Rigg - royce - 06-03-2018
(Well, it's not *strictly* a 100% requirement for some attacks - but definitely required for others). You should try to get as close to that as possible, though.
