    Thread: speed and length
Post: RE: speed and length

No, it absolutely is not the best card to buy for oclHashcat. You are sorely mistaken. 2x 290X are cheaper, faster, and behave much more civilly. GTX 980 however is the all-around best card to buy. ...

    Thread: speed and length
Post: RE: speed and length

NBZ hasn't been around for ~ 6 months. But IIRC what he ended up doing was upgrading the radiator and adding two larger fans to the GPU. Then he had to set the clock to 1000 Mhz and Powertune to 0% or...

Post: RE: speed and length

Again, it's not just about temperature. It's also about how much power the card is drawing. That's why it's called Powertune. The firmware on the GPU will not allow the card to draw more watts than it...

hybrid attack would be much faster than using the rules engine for that, and it scales better.

you're using your graphics card for password cracking, while also playing a game that makes heavy use of your graphics card, and you're wondering why the speed drops?

Post: RE: Speed drop after playing game (Crysis3)

why are you using --gpu-loops 128? 128 is the default, you do not need to manually specify that. and you will not get full acceleration using the default of 128, you need to use 4096 for full accelera...

Yes, it is normal to see ~50% speed reduction for multi-hash vs single hash.

md5crypt is salted, so each password candidate has to be re-hashed with each unique salt.

Post: RE: Speed on Radeon HD6970

correct, you can essentially cut atom's 6990 speeds in half. it will be a little bit faster due to higher clocks, but that will give you a good estimate. I believe d3ad0ne may also have some 6970 ben...

You must not read the forums very often. 1. Catalyst 14.12 is horribly, horribly broken and is not to be used. You must use exactly Catalyst 14.9. 2. If you are using 14.12 that means you are al...

Post: RE: Speed Problem with R9 295X2

Power supply is irrelevant. The 295X2 requires nearly 550W when using oclHashcat, but it is only a 500W card. So the firmware will throttle the GPUs to keep the power draw under 500W. This is what AMD...

Post: RE: Speed Problem with R9 295X2

Benchmark only runs for a few seconds, not usually enough time for it to throttle. It's also possible that you were not giving your GPUs enough work to do in your first screenshot.

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.

Because the left mask keyspace is too small and therefore you're not giving the GPU enough work to do.
