1 Ekeys/s (1021708069969158067 keys/s)

128gb + 16 AMD Ryzen 7 5800X

I think I was getting about 450/620Pkeys/s on Ryzen 5950X/32GB with k=1440/2048 on #120
Would like to have 128GB on my system but that's impossible due some reasons

I use a mini-itx board so only two dimm slots available. Plus I just want to use b-die sticks which is a total limit. Seems there were G.Skill 2x32GB b-die kits in production but it's almost impossible to find or the price is oof

Until any other option becomes visible, it may be necessary for me to resort to such foolishness.

who is fast in programming, try to make such an analysis.

for example rmd160 puzzle 66 like this

for every 1048576 step of puzzle 66, will fall around ~36000 "1" 73, "0" 87 and if we add fishing on the first 20 bits (for example)
001000001101010001011010011010100111011000100101001101010111000000001100111010011110000010110010000 1011011100011000110011001010000110011010111011011100010100101

then, based on the probability of dropping 20 bits, you need 1048576 outcomes

1048576/36000 29

1048576 × 30 31457280
1048576 × 29 30408704  there will be only 1 00100000110101000101 "1" 73, "0" 87
1048576 × 28 29360128

what is a full turn for example by 3

001
100
010

there may be such

100
100
001

etc

but in theory, when hashing, the data is simply shuffled, that is, rotated

this means that 20 bits (1048576  steps) in the first 00100000110101000101 will simply move to another place in the second (1048576  steps), third (1048576  steps), etc.

1048576×1048576 = 1099511627776 1 twist

2^65/1048576 = 35184372088832

35184372088832/1099511627776 32 twists for all puzzle 66


1048576×32 = 33554432 (there will be only 1 00100000110101000101 "1" 73, "0" 87)

2^65/33554432 = 1099511627776

all puzzle be

33554432 steps by 1099511627776 len or

1099511627776 steps by 33554432 len  

during the analysis, 1-3 drops out on such steps

we can rotate this space as we like, even take a square

6074001000
6074001000

imagine that we fill with zeros those addresses that do not suit us according to the sorting criterion and mark 1 those that do

we will get a similar picture

000001000001000100000000000000000001000000100000000000000001
001000000000000010000000000110000000000000000100000000100000
etc...

if we take another piece of 20 bits from the address, it will behave similarly

11011011100010100101

so these pieces will jump around the whole puzzle according to the random distribution and in total, as I wrote above, there will be 32 full turns

the idea is to take and randomly generate all possible collisions

select statistics from the puzzle space and try to jump by sorting the template

In my humble understanding, he -as many others- thinks that there is a pattern and he tries to predict it. But it's as simple as the puzzle creator said: THERE IS NO PATTERN. The puzzle creator would not be so foolish to use a predictable pattern, would you in his position?
