My system is overheating. If I set the thread count to 0, does this mean it is not using any CPU and only using the GPU?

If you'll set "Number of threads" to 1 (it's minimum value) then our software will not use CPU threads at all, only GPU ones. However, at least one CPU thread will be running for each GPU. It won't do...

I bought AccentWPR. How can I use GPU password recovery and do I need it?

GPU is not supported in AccentWPR. It is supported in AccentOPR. But it's very important! GPU password re

Can I use password searching on GPU if I work on a virtual machine?

No, unfortunately, it's impossible. When using virtual machines the system does not provide an opportunity to work with GPU through video card original drivers. I.e. the programs cannot connect to GPU...

How faster one can crack RAR passwords on AMD HD 7990 than on HD 6990?

We haven't done any tests with 7990 specifically, however AMD GCN architecture (which 7990 based on) is even better than previous AMD architectures for RAR password recovery. Single 7970 shows speed...

I can't make my video card to search for the password set for my Zip archive. What is the reason?

GPU support for attacking ZIP passwords with classic encryption is restricted. It is available just for a brute force attack if you don't use masks. GPU is also not supported for a dictionary b...

I assembly a high-performance system for GPU password recovery based on AMD video cards. What shall I focuse my attention on?

Yes, AMD is better for password recovery. But there are two moments: Load on GPU reaches 99% when our software runs. It means that the video card significantly heats up and a high-quality power sup...

I assemble a system for GPU password recovery. What video card is better - AMD or NVIDIA?

Generally, NVIDIA is behind AMD as it concerns performance for GPU password recovery tasks.

Is it possible to find out if GPU password recovery will run on my system?

You can find out at what speed our GPU password recovery software will run on your system yourself. Just install a demo version of the program and try it using a test file. Here are the current versi...

I see no difference between the speed of zip passwords recovery on GPU and without it. What's the problem?

If ZIP archives with classical encryption (96-bit keys) are attacked, GPU is used to accelerate the process during a brute-force attack and provided that a NVIDIA video card is installed. You ...

ERROR 303

Q: When I use GPU to recover the password, error 303 appears. What this error means and how can I eliminate it? A: The error appears i

Do your programs work applying NVIDIA CUDA video cards?

Of course! The GPU kernel of our software works applying both GPU computing technologies: NVIDIA CUDA and ATI Stream. There is one condition: the GPU kernels connects only on licenses higher t...

How many GPUs does Accent Password Recovery/Passcovery Suite supports?

For GPGPU you don't need to link GPUs together, actually it can even brings another compatibility problems. The main limiting factors here are - number of PCI-E slots, size of videocards and drivers....

What is the minimum configuration of computers for best performance?

As for minimum configuration -- it's recommended to have one CPU core per each GPU core though fast enough CPU usually can handle several GPU threads. It's always better to have, for example, 2.4Ghz ...

GPU error code 3xx

The bug is related to the operation instability of your GPU. Our software uses 100% of video card capabilities. It requires good cooling and sufficient capacity of the electric power unit. In your si...

Is hardware connections (i.e. CrossFire bridges) between GPUs for software operation required?

No, you don't need hardware connections (i.e. CrossFire bridges) between GPUs for GPGPU application. Starting from ~11.9 drivers AMD finally removed monitor-attached-to-each-card requirement, so now i...

How can I be sure that your software will actually use my GPU?

Trial version uses GPU if it's possible, so if it doesn't -- your GPU is not supported. Basically you're need NVIDIA G80+ (8600GT and above) or ATI RV710+ (4550 and above) video card to get GPU acc...

Zip Password Recovery speed on the new GTX770-series GPU is lower than that on the old GTX570 series. Why?!

The reason is the new NVIDIA video card architecture. Despite the high nominal number of CUDA cores in the GTX770 chip, it uses fewer cores than the GTX

Is simultaneous work of Passcovery programs on AMD and NVIDIA video cards possible? Will there be any problems caused by differences in OpenCL?

Yes, it’s possible. No, there will be none. Simultaneous work on NVIDIA and AMD GPU’s All current versions of Passcovery products with GPU s

Graphics Card Selection for GPU Password Recovery

GPU password recovery is always a significant increase in the speed of an exhaustive search. Which graphics card do you choose for this purpose? What do you need to pay attention to? What feature...

Is password breaking accelerated on the GPU with an increase in videocard memory?

No, it will not be accelerated. The amount of videocard memory does not affect in any manner the speed of password breaking of passwords. For password recovery on the GPU, the videocard memory (as ...
