ok!! best set up for 4090 and 5090??

Thanks for the tip!

ok

I used BitCrack with the same base command but manually tuned the -t, -b, and -p values for each GPU. I gradually increased these parameters until the GPU either crashed or was about to crash, then backed off slightly to get the maximum stable performance.

Someone in the group chat managed to push their RTX GPU to about 5356.87 MKey/s, which is higher than what I got. They were likely using a different GitHub project like KeyHunt-Cuda, which can sometimes achieve better raw speed. However, in my tests, I noticed that KeyHunt-Cuda occasionally skips some keys, especially with test/fake keys, which could lead to missing targets.

BitCrack, on the other hand, is very thorough and doesn't skip keys, so I prefer it for reliability, even if the speed is slightly lower

bro i try  -b -p -t  but

true i few GeForce RTX 5090  will do the job for much less, the h200 is for Ai task using 4 RTX 5090  i can achieve  1_382_400_000_000_000  x day

for now i try few gpu

NVIDIA RTX A5000  1338.56 MKey/s

GeForce RTX 5090  3956.87 MKey/s  top

GeForce RTX 4080 SUPER 1725.58 MKey/s

GeForce GTX 1070 119.88 MKey/s

H200 NVL 1988.08 MKey/s   


any way to cut the key or skip consecutive number and letter smart way?

is possible thanks, but im worry maybe will jump the key since i notice few GitHub project where sometime miss the key so is better to stick with RTX 5090 or RTX 4090 or even few  4080 should do it my target is to scan chunk_size = 900_999_999_999_999 daily, and maybe hit the damn key

bro im not sure why

wtf i try the nvidia h200 and is just doing 2.8–3.0 billion keys/sec i was expecting more how can i gpu of  $31,000 to $32,000 do such low or im doing something wrong??

guys best app to use i try BitCrack but the result are not good, and some others app miss the key exemple KeyHunt-Cuda is good but he keep missing the key

BitCrack result

no true bro 21 days with 50 GPUs running at 2,896.62 MKey/s each

TRUE BUT DEPEND ON HOW MAN GPU
 The total number of keys
From:  0x4000000000000000 =  4,611,686,018,427,387,904

-----------------------------------------------------
Diff:  0x1000000000000000 =  1,152,921,504,606,846,976 keys  if im not wrong 5.55 hours using 20 gpu   please correct me??

Thank you bro i will try
