So went with the nuclear option (a bit of an easter egg in there for you also @codinghorror ):
Was struggling previously to get above 50-60% CPU utilization previously on a 5800x with 2 drives connected with lanes to the CPU and a third via the chipset, so upgrading this rig to have 5 ssds connected with lanes to the CPU (I’ll be using the other m.2 slot with a P4610 connected). So hopefully this will allow me to max out CPU usage a bit more.
Would anyone suggest eventually upgrading to a better CPU for this rig also? Potentially thinking about upgrading to a 5950x when it’s possible to find one.
Curious to know how much this helped. Looking forward to seeing an update with your results
I don’t have hard stats, but from monitoring with
glances before and after my average CPU usage has probably increased from around 60-70% to 95%, so CPU is definitely the bottleneck now. Still the occasional spike in iowait, but nothing like the constant 15-20% I was experiencing before.
I also have this ASUS HYPER card in both my ryzen 5950x machines (yes, I ordered another one… I am a glutton for punishment).
I assume this was more than 5 days ago since it seems impossible to find them anywhere now? I think I may have actually got one of the last used ones from ebay.
60-70% up to 95% seems like a great jump. Please do update if you see a noticeable increase in plots/day
I got a used one from Amazon warehouse a couple days ago, with a “thanks to you, this product got a second life” sticker, lol.
I’m also having the same problem with High CPU IOWaiting, and came by this post.
After reading through this post, I’ve also just ordered a Hyper M.2 X16 Gen 4 Card V2 board, which should arrive by next week.
I’m wondering that what setup did you use to solve your iowaiting problem.
- Did you use raid on the m.2, if so what raid are you using?
- How many m.2 ssd do you have in total?
- Are you running with bitfield or not?
- What is your average time for 1 plot to be plotted before and after you’ve fixed your iowait?
