C1 to C9 are the original GH plots, C11 and upwards are the newer updated compressed plots. The new farmer is also more efficient and can farm more of the C1 to C9 plots than the first version could.
3080Ti is not listed in that chart, its shows a 3060Ti.
A 3080Ti is roughly 70% more powerful than a 3060Ti, so should be able to farm about 1.7 times as much.
Yes, thanks. I meant 3060 Ti.
On the C9 vs C16, do you mean C16 is a new and improved format and so it makes sense to go with C16 to take advantage of the improvements?
C10 to C20 are the new improved plot format, and can only be farmed with a GPU.
Are the C compression numbers all āstandardā format plots ? I continuously see lost of mention of C0-C7, C8-10, and now C11-C20. Itās confusing, as it seems some C levels are Chia Bladebit levels (as well as othersāā¦), whereas it now seems that C11-C20 are MadMax only stylee plots.
There is obviously something different to each of the compressed plot vendorsā formats, but it would be helpful if there is a table somewhere that shows what compression levels available from whoās software/technology.
Most people just seem to refer to everything as āCxā with no regard to whoās plot tech they belong to. Perhaps because they already know. Some of us donāt. 
I understand some confusion and thatās likely to never really go away.
But I would imagine most people in this topic are talking about Gigahorse plots, unless otherwise mentioned.
Gigahorse has C1-C9 (old format) and C11-C20 in the optimized new format.
Bladebit has C1-C7
NoSSD has C1-C5 (old format) and C10-C15 in the new optimized format.
The real issue is that itās a lot of data to compare. Compression levels do not match in terms of filesize, but also not in terms of required compute (as in how much can GPU X farm). Then there are also difference in toolsets and how they operate / what they require. Hard to make any sensible full comparison list.
Best is just start from your hardware/farm size and compare at some specific levels only
One thing that is always the same though: a K32 plots is a K32 plot. This is regardless of compression, it holds a certain number of proofs and therefor has a certain value on the blockchain.
Thanks, and yes, you have summarized what I have found confusing since first looking at compression a few months ago. I have yet to plot a single compressed plot.
I also found a similar table over on xch.farm website. Perhaps, using your examples above, they should have referred to their plots as:
Gigahorse: GC1-GC9 and GC11-GC20 (or āMā for MadMax, MC1-MC9 sounds betterā¦)
Bladebit: BC1-BC7
NoSSD: NC1-NC5 and NC10-NC15
Too late now I guess, unless everyone gets onboard. Maybe itās not even necessary to some, but confusing for a newb to compression.
Yes, the āCā levels of the different technologies that are currently on the market is not optimal!
especially since Cx is not equal to Cx of the different technologies.
a clear differentiation would really offer added value for everyone, for example as you suggested.
to achieve this it doesnāt even need the developers itās enough if just everyone uses it this way on discord and in the forums.
then it goes into automatic use and even the developers will probably use it that way later.
Yes. Iāll start.
I like the idea of sticking with official technology and my initial thought was to re-plot BC7ās.
The ease, speed, resource and high compression of NoSSDās farmer and plots (probably NC15ās) is a draw, but nagging concerns about what the software is doing in the background persist for me. Has anyone spent more time since the initial scepticsm with a packet analyser, disk I/O analyser etc ? Even if there is nothing untoward going on in the code, a concern over some kind of future hack/attack/rugpull is still there for me.
So that leaves MC20ās. Does anyone know of a GigaHorse getting started guide ? Github page seems to assume youāve been using it since inception, rather than coming from a complete OG plot background.
Normally I would just dive in a spend some time with it to get going but itās time I am lacking at present.
No,no, its GC20 
OG, NFT, BC1-7 and GC1 to GC20 are all supported by the very latest GH farmer.
Short on time, so Iāll keep it basic.The first thing you is create a few plots say GC17 to GC20.
Then use the Proof of Space to see how much your system can farm - make sure the plot is on an SSD and your not using the GPU for anything else.
Then when ready to start replotting, download the GH farmer, make sure any other Chia processes are closed, if you use the GUI that must be closed, then run the GH Farmer, once that is running you can reopen the GUI, closing that will close GH Farmer. If you donāt use the GUI then its just normal CLI but using GH Farmer.
I only very briefly used GH Farmer before going BC7, currently using Foxy-GH-Farmer and Foxy-Farmer but once Iām done replotting I will switch to GH Farmer and GUI.
Chia GUI version and GH Farmer version must match.
Hello everyone, I started to replot to C19, have over 100 plots already, but Spacefarmers io doesnāt see my new little farm. Has anyone same problem? On CLI plots are visible, farm is syncronized.
I had a similar issue and the problem for me was I had changed the plot refresh time to 1 day and so my farm was not seeing the new plots. Changed it back to 3600 and now seems to be working properly.
Starting to replot to GH plots and in reading the readme, it says āThe compressed plot harvester and farmer are not compatible with the official Chia node, it only works together with the Gigahorse node. However itās possible to use a wallet from the official Chia repository, instead of the Gigahorse binary wallet.ā
How is the GH binary wallet different than the official Chia wallet? Iām thinking my wallet is just an address, right?
Also, how do I tell when I send my 0.25 XCH to Max for fees?
The wallet is separate thing that you can run standalone (and also the address where your chia are too)
The reference wallet has features first that might be ported to g.h. later
Presumably it will be in the logs, I havenāt had it happen yet, so donāt know.
Partial appeared, seems that reason is small farm size.
use the pool_login_link to login to the pool dashboar and check the difficulty setting, maybe too high for small farm
You can actually just use the official Chia GUI.
Just make sure to start gigahorse first, then launch the Chia GUI.
last GH release currently works with Chia 2.1.1
(you will still get a warning āincorrect versionā, but you can ignore it)
Well, I was feeling realy hyped about the new compression levels and now that I have some time, Iāve just had a little read up. I have a small farm with 353TiB (actual) and 499TiB (effective) C8 and being farmed with a Tesla P4. I wrongly assumed that Iād be able to replot to C18/19 and all would be good, however, if Iāve read this right, it looks like the highest compression level that Iād be able to farm would be C16 up until June 24 filter change and C15 after. Please could somebody confirm if Iāve read this correctly as this would mean that Iād need to buy a high end GPU just to farm which is just not worth it for me.
Also, the C15 plots seem to be around the same size as the C8 that I already have, so would there be any point in replotting?
Create some plots and use the ProofofSpace to check how much you can farm. make sure nothing is using the GPU when you run it, and the plot should be on a SSD.
I very much doubt you will be able to farm C19, I have a 3060 (non Ti), and its just capable of farming circa 320TiB raw of C19 plots. I will need to replot come the filter reduction.
If you have a spare slot why not just get another P4, they are cheap and low power and use two cards? Just check two P4ās will cope with the plots.
Thanks Ronski, I didnāt even consider that.
