I have i9-10900, 128 GB RAM, and results were basically similar to MM, maybe in the range of 1 minute faster (~30 mins/plot), so I gave up testing / tuning. Plot time 33 min and 434 GB write, much better than alpha 1, MAdmax win on ssd write : 387GB < 434GB, but bladebit faster. Each plot takes up storage space on your hard drive and represents your chance to win rewards in Chia farming. But when I run with the chia_plot command with DEFAULT number of threads (4), RAM usage is consistently high at ~48Gi. Madmax is configured for same location for the final plot dir to eliminate the overhead of transferring plots to a separate drive, allowing the next plot to start immediately… (I use a script for transferring files). Jun 1, 2021 · You’re trying to plot too much at once. So if you'd like to maximize cache usage you may try increasing the bucket count (the memory requirements get halved with each Jun 5, 2021 · This kind of stuff (using RAM as cache, and the swapfile, not to mention RAM compression) is usually handled transparently by the operating system, so the software people peddling this solution are saying “we are smarter than the people writing the operating system”… unless it is some extremely specialized use case, I highly doubt that! Plotting + RAM + Farming Settings and Hardware Question. Once I switched to Ubuntu, all was over. You can get DDR4-2666 ECC RAM for $150 per stick and at that cost, it is $2400 just in RAM. Jan 20, 2023 · Summary. Read the github instructions. Disk-based mode Chia plotting is the process of creating files called "plots" that contain cryptographic proofs used during farming. Write performance can be sheltered a little by the onboard disk cache (assuming write caching is enabled). 11 threads didn’t work that well in the past. 1. AMD confirmed this back in 2019 that each CCD/IOD link is 32B/cycle for read and 16B/cycle for write. Chia plotting is super write-intensive. chia plotters bladebit2 -f <farmer key> -c <contract address> -r <thread count> -u 64 --cache 100G --alternate -t /mnt/ssd -d /mnt/hdd. 1 and it’s error My system is windows 11 AMD Threadripper 3970x 256 gb of ram and rog rtx 3070 8gb CLI Plotting If you are unsure which plotter to use, the Plotting Software page will help you to decide. 1 % (155. madmax+ram 110GB ram-disk. I’m looking at hardware to do more plotting more quickly (I’ve previously plotted on SSD drives, not RAM disks) and find the sweet spot for hardware in terms of cost is with Jun 8, 2021 · I love cake! But I am worried - caching gets tricked by chia plotting. tmp files that can be removed. With parallel plotting on that CPU I suspect RAM bandwidth and L1/L2 CPU cache are the limiting factors followed by possible SAS bus saturation. I don’t have a single plot at a time log file kicking around so I cannot verify that number, but it sounds about right. Compressing tables 5 and 6 Step 1 completed step in 8. regards. Jun 1, 2021 · Update: I’ve been plotting with my HDDs with the help of PrimoCache pretty well so far. Point #1 is covered by setting a read cache, and point #2 is covered by Defer Write. 1%. Plot grinding, spoofing plots with GPU, can be theoretically performed once phase 1 is under 28 seconds, but isn’t economical and requires The fastest plot creation is done completely in memory, but requires a server with a large amount of DRAM (256 GB for BladeBit CUDA, or 416 GB for BladeBit RAM). Time to finish for both plots: 13h. GPU performance and i/o bandwidth are growing at a rapid pace. Back to disk plot. io lk ri qp io rt ug im qm ph
