I was recently getting some office supplies from Office Depot and I always walk down the electronics isle just to check if there is anything interesting or if there are any good deals. They had an HP PC (shown in the image) on sale for $550 USD. I almost walked passed it when I noticed that it had a Ryzen 7 processor. I thought that it might have been a 3000 series processor, but to my surprise, it was the 5700G. I didn’t even realize it was released yet. I saw the specifications for it and was even more surprised. From the Office Depot website:
|Processor||AMD Ryzen 5700G (8c/16t)|
|RAM||Two Slots available|
One 16GB stick populated
|OS||Windows 10 Home|
|PSU||180W 80Plus Gold|
As you can see, this seems like the perfect beginner Chia Plotter machine. I purchased the system and brought it home. I then ran tests on it to better catalog the system:
I then tested it to see how well it performed with a solo plot on 1.1.5 of the Chia Client. I installed the OS on its own SSD to leave the NVMe free to plot. I also installed a 2TB HDD to store the plots on. The setting for the plotter was 8threads and 3432RAM.
|Plot times||K32 |
This is a pretty terrible time for this processor. Something else must be going on here that bottlenecks it. Looking at the long phase 3 time, it looks like it might be the NVMe. I have parts from my other plotter and did troubleshooting to find out what was the cause, here are the results:
|Plot Times||Stock||#1 |
32GB (2×16) RAM
- #1 – For this configuration I just wanted to try an NTFS Allocation size of 128K. It failed in the 2nd phase due to running out of space on the 256GB Hard Drive, which makes sense.
- #2 – Here I swapped out the 16GB stick for two 8GB sticks to enable dual channel RAM. Here is where I discovered that the HP does NOT support XMP profiles. This 3200Mhz kit can only run at 2666Mhz without XMP. But, we can see that even though the RAM speed was less, it still finished faster than the single channel configuration of stock.
- #3 – I kept the same RAM configuration here and swapped out the NVMe for the Inland (details on my about page). Here I saw the biggest boost to speed. Over 10 000 seconds shaved off the solo plot time. This is more inline with what the processor can do.
- #4 – Here, I purchased another 16GB RAM stick from Team Force (amazon affiliate link). This enabled dual channel but at the 3200Mhz Speed instead of the 2666Mhz speed. It also gave me 32GB of RAM instead of 16GB. We saw just a small improvement here in plot times. This is probably due to the fact that the 3200Mhz RAM is running at CL22. Until Ryzen Master support is enabled, there isn’t any way to change RAM timings on this machine.
This is a very capable machine. Also the price for it in today’s environment is also very good because it doesn’t need a video card due to the built in graphics that it has. There are a couple things that you are trading though. Here are my list of Pros and Cons:
|Pros (Positives)||Cons (Negatives)|
|++ Price ($550+tax)|
++ No Graphics Card Needed
+ M.2 Slot and NVMe Drive
+ 16GB single channel RAM
+ 2 Open SATA ports
+ Open 16x PCI-E Slot
+ 5Gbps USB 3 ports
+ USB-C port
+ Windows 10 License
|— Proprietary Motherboard|
(Can’t use 3rd party Mobos in Case)
(Can’t use 3rd party PSUs with Mobo)
— 180W Power Supply Unit (PSU)
(Can’t add good Video Card that needs power)
— Does not Support XMP RAM
– Ryzen Master does not support Processor yet
– Uses Torx screws for everything
– Only supports two monitors
(one HDMI and one VGA)
(USB-C port does not support a display)
In terms of the 5700G, it is very good, but not as good as a 5800X in terms of plotting speed. But, you are also spending a lot less money ($550 for a system instead of $450 for just the processor). If you 1) replace the NVMe with the 2TB inland, 2) add the second 16GB stick, 3) Buy a PCIe adapter for the Kioxia NVMe to use as the OS ssd, I think it would be able to do 8 plotters in parallel, resulting in 2.4 TB plotted a day if the plots can be made in 8 hours or less each.
Keep on Farming on.
