That is indeed a reference design card!

Post: RE: 980GTX MSI vs Reference

There's nothing special about superclocked or factory overclocked cards. They just have a bios that comes set at higher clocks, which you can easily do yourself.

Post: RE: 980GTX MSI vs Reference

I never said reference designs cost more -- I said they cost more to manufacture. And the chipset manufacturer dictates the price, therefore the profit margins are very slim. This is why several OEMs...

No, oclHashcat no longer supports SL3, and hasn't for quite some time now.

Post: RE: 1080 TI - new best bang for buck?

R9 Fury X was never the best. GTX 1080 Ti and GTX Titan XP should have clock-for-clock identical performance. But it won't have the best bang for the buck. If we look at MD5 perf per dollar: GTX...

Well... Yes and no ;) You're correct: you should take the total build cost into consideration. There's a reason we do not offer the GTX 1070 in the Brutalis in a clustered configuration, it throws t...

Yeah I didn't realize until later that the price points Nvidia advertised were for OEM cards, not FE. We used FE prices when calculating the new Brutalis price points. However, if you're simply looki...

Look at the block diagram for the board. The board has 4x PLX chips, two per CPU. That means each CPU directly controls two GPUs on two PLX chips. So you need both CPUs. On older models you could get ...

You can also use attack mode 6 (dict + mask) with oclhashcat-plus and use the salts as a dictionary.

It's a really bad idea, all you're doing is wasting disk space. And if you have a 100 GB wordlist, you're doing something very, very wrong.

GPU makes sense -- as I said, you should not be running straight wordlist attacks against fast hashes on GPU. However, there shouldn't be that much of a drop between single hash and multihash on CPU. ...

Rainbow tables don't actually store the hash value, they store hash chains using a reduction function. So you still have to do quite a bit of calculation and false-alarm checking to look up a hash in ...
