Here are some performance posted in discord - credit to tclarke.                                                               =================
CPU:ryzen threadripper 1950X @ 3.4 Ghz
Threads:32  
OS: Ubuntu
Memory: Quad DDR4 3200
Option: sseboost 1
Hashrate:5378 h/s

The 16 real cores threadripper is a 1000$ CPU + the cost of the rest of the PC.  You would have to be out of your mind to buy it just for mining.
It's complete AMD garbage.  I have a Ryzen 7 2700x and it's complete garbage compared to any old Intel I have.  It will not post at advertised ram speeds of 3200.  I have 3200 DDR4.  AMD will only post at 2866 unless I pay for special AMD RAM.

Xeon E5 v3 ES cost me 400$ few years ago and it does:

3400 H/s.  Memory Dual/Quad/Single (DDR4 2133) - no difference.  sseboost 1 slows it down.

AMD CPUs are extremely dependent on the RAM type and speed.  DDR4 is not meant to run at 3200.  That's OC speeds which will boil it.

Socket WTF that's the biggest CPU I have seen in my life (4 glued together dies on one CPU).  The threadripper requires special cooling.  Big ass plate.  Needs water at that TDP to run it 24/7 at 100% load.

There are believers of PascalCoin, who will support the coin in any way they can. : )

I never said I'm not a believer.

Maybe I am a hypocrite and have 100 AMD Epyc 7601.  It's only a 5000$ CPU 

Why settle for 16 real cores when you can have 32?  More is usually always better.

What coins is this miner for? Just Pascal?

[redmonski]

Yes, the rhminer is just for the RandomHash algo used by PascalCoin.

No other coin is using the RandomHash algo - it was invented by one of the devs. It’s a cpu friendly algo, a mid range intel cpu can beat a gtx 1080ti.

You can give it a shot and mine here - pool.pascalpool.org

RandomHash was design to be much slower on GPU.
There is alot of rooms for optimizations toh, but it will never beat a cpu in term of $/hash.

That GPU HR is likely from me.

It's a 1080ti (there is no 1080 with 11GB of GDDR5) with ~ 400 threads.  Max Hr was 300 not 400 but a cheap CPU principle is true.

My i3-4030U CPU @ 1.90GHz does:

Kali/Ubuntu.  Almost the same.  I use the first one.

That sounds about right.  It's a high frequency 6 core CPU.  My mini PC has a low frequency dual core.

I use this command to watch how bad the CPU throttles or if it's speed stepping properly.

It will jump around a lot.  It's normal.

Code:

root@mac-mini:~# watch -n .1 "lscpu | grep MHz"

To monitor the temps

Code:

root@mac-mini:~# watch -n .1 sensors

For those who want to know RandomHash, below is taken from the website - pascalcoin.org.

RandomHash - GPU & ASIC Resistant Hash Algorithm

PascalCoin adopts a low-memory, GPU- and ASIC-resistant hash algorithm called Random Hash - the first of its kind - that fully preserves mining decentralization. Random Hash is an innovative, "high-level cryptographic hash" algorithm that combines other well-known hash primitives in a highly serial manner. In addition to RandomHash’s serial nature, it is branch-heavy and recursive which makes PascalCoin optimal for CPU-only mining. RandomHash is designed to ensure PascalCoin remains a globally decentralized network that runs well on low-end hardware.

Technical specifications for Random Hash can be found in the whitepaper.

I'm surprised that the PascalCoin still exist, where's ann thread for PascalCoin, and which exchanges are supported PascalCoin nowadays?

Here's the Ann thread - https://bitcointalk.org/index.php?topic=1583719.0
But you may want to check the discord, that is more updated with the current developments.
And RandomHash is the new algo, to move away from the dual mining ecosystem and make it more cpu friendly coin (hardfork was last November).

Besides Polo, there are also a number of exchanges that are now supporting PascalCoin, https://www.pascalcoin.org/ to check the list of exchanges.

And just recently - open source mining pools (we have now 2 in operation).

The project is progressing quite good my friend! Be sure also to check out the PascalCoin Improvement Proposals (PIPs) to see what's coming more in PascalCoin.

I am surprised too.  I'm glad I sold all mine.

Wait, if you know that it still exists, the ANN thread was where most people would find out about it.

Being funny is not tolerated in this forum. 

This is about rhminer and RandomHash.

You can read the specifications here https://github.com/PascalCoin/PascalCoin/blob/master/PIP/PIP-0009.md
and implement a super fast FPGA ASIC miner to make profits.

HF happened around 5pm EST on November 14, 2018.  I have it on a sticky note.
I soloed 4 blocks an old CPU.

Agree with you PascalCoin is promising project. I'll give it a try and mining PascalCoin and see its profit. thanks to you clear information you provide.

I'd like to ask why you are so glad to sold out all your PascalCoin?
as I know that the PascalCoin is ASIC -resistant hash algorithm.

I probably didn't.

It is ASIC resistant for now.  Does not stop someone clever to figure out another way.

There is a long list of coins that were announced as ASIC + other resistance.  There are ASICs out there for all of them.  Including PascalCoin (before the HF).

It's not GPU resistant.  At least once a developer wrote his own miner that was extremely fast (I forgot which crypto coin) and made a nice profit.

That's why these algorithms are public information.

Hi,

I'm new to all this but have got a a couple of old servers mining plus my desktop.  My problem is that rhminer is not finding my GPU.  I've checked it's supported and it is (GTX 770).

When I ran the rhminer -list command all I got was CPU information and when trying to run using the GPU I get a message something like -gpu is an invalid command.

Does the card require a specific driver version?  Any help would be much appreciated.
