    Thread: Speed Problem with R9 295X2
Post: RE: Speed Problem with R9 295X2

No. Again, power supply is irrelevant. The card will do everything it can to keep power consumption under 500W, and that means throttling the GPUs.

    Thread: Launching an attack NTLM
Post: RE: Launching an attack NTLM

Syntax is wrong. The proper way to format the above command would be: Code: -- oclHashcat64 -m 1000 -a 3 -i -o C:\output.txt Localhashes.txt ?a?a?a?a?a -- Note that I have omitted "max=10" b...

The flag is actually --increment-max but it doesn't really have much use in the real world. In most all scenarios the maximum will simply be the length of your mask. If you wanted to brute force ?a...

Post: RE: Require a little help here.

Yes, that's a reference design card. But not because it says "nvidia" on the board, I believe most if not all say that.

Yeah, power and heat are definitely a challenge with the 6990. It's a 425W card with a TDP of 375W. You may have to do a little underclocking to make it happy, or start seeking exotic cooling solution...

It's an okay price. They're selling around $130 on eBay right now. I personally think they're far more hassle than they're worth. We ended up with 24 of them, then promptly sold them all and replac...

Power is always an issue. The more power a card draws, the harder it is to cool. 5970 is the same length as the 6990. They are both dual-GPU cards.

There's no real market for used GPUs now that GPU mining is dead, so used GPU prices are incredibly reasonable right now. Have a look at what's on the market, I think you'll be surprised. 7970s are se...

Completely disagree. As stated above, we had 24x 6990 and we couldn't get rid of them fast enough. The only card I've loathed more than the 6990 is the 295X2. The 280X is just a re-branded 7970 tha...

I think you mean Hashcat's fingerprint attack (https://hashcat.net/wiki/doku.php?id=fingerprint_attack). And no, PRINCE is not a fingerprint attack.

:0.1, not 0.1 But if you have 290X you should consider od6config instead of amdconfig.

because --output-file is not a valid option. read --help, read the wiki. also you're using an old version of hashcat.

Sorry, this is not possible. Also your math is wrong, the keyspace would be 95^35. Not that it really matters.

You would be able to reduce the keyspace with a targeted mask attack, but I don't think it will matter much.
