Gigahorse 3.0 has been released: Release 2.1.4.giga30 Gigahorse 3.0 Node / Farmer · madMAx43v3r/chia-gigahorse · GitHub
New in this release:
Gigahorse 3.0 plot format, C30 to C33
Fixed an issue with remote compute where fail-over to another server did result in a lost lookup once every 100 sec. (ERROR: connect() failed with: Connection refused)

Limitations:
The new C30 to C33 are only supported with the CUDA plotter (cuda_plot_k32_v3, 8G RAM minimum)
Farming C30 to C33 is only supported with Nvidia GPU (starting with 900 series)
K32 only for 3.0 format

Notes:
Need to use cuda_plot_k32_v3 binary for plotting the new format.
Partial difficulty is now even more important for maximum farm size. Minimum recommended partial difficulty is 10k for the new 3.0 format.
Using a too low partial difficulty will increase GPU load by a factor of 2, in the worst case.
Higher -S can help with phase 3 plotting times, like -S 8 if you have enough VRAM.
Use ProofOfSpace farm --diff 800000 to benchmark for solo farming.
chia_recompute_server is backwards compatible to old clients, but needs to be updated for new clients running giga30.
Both Node & Farmer & Harvester need to be updated at the same time to support 3.0 format.
Lower levels of the 3.0 format to replace C16 to C18 will be released later (work in progress).

So, no CHIP-22 at this time ?

Arm race never stops.

What desktop 30xx 40xxs gpu equivalents RTX A5000? Thanks.

Here are some initial Farm size calc’s and Plotting times.

Waiting for C26 - C28 improvements…

What sort of farm size can an RTX A4000 (16GB) do at C31, would it be around 600GB native.

Any idea on how to set difficulty on Space Pool?

10

Does difficulty need to be set now if solo mining.

11

They don’t equate precisely, as the Ax000 series tends to much lower clocks on higher core counts than the RTX 4xxx series (down side of their lower power consumption in general).
Probably the closest equal would be ABOUT a RTX 4070.

For those of us with older cards, the 3060ti is fairly close to the 1080ti.

No, there is no changing difficulty when solo mining, only when using pools.

13

It’s been a while since I’ve been on Space Pool, and I do believe it was very limited range you could adjust on Space Pool. Some of the other pools have unlimited adjustment of difficulty. It’s pool dependent.

Need to try Foxypool…

I got this 2 errors on C30 on Space Pool. need to set difficulty. When removing C30 everything goes back to normal

330 c30 plots and pooling on Foxy without issue, mind you I’d had my difficulty set to 120 for the last 10 hours, just changed it to 1000, and I’ll increase it as I add more plots, so we’ll see what happens.

Hi. How much RAM is needed for plotting without SSD, as before - 256 GB or 128 GB?
And which pool can I farm on now? Spacefarmers.io they write the following:
“Currently, you can’t use this version with our community nodes. We are working hard to get the new nodes ready.”

Only with Fast Farmer.

Will be very close, maybe run a mix of C30 and C31.

Same as before, 256G.

Hi @madMAx43v3r

I am having this message when plotting C31

My Spec’s:

At least 3 attempts, rebooting, but still the same message.

Any recommendation?

Really strange, it fails to allocate normal host memory. Did you use -M 128 ?
