Yeah the mining motherboards are crazy expensive right now. Like $300 plus

Needs a bit of advice from some of the server motherboard gurus. I'm doing some crypto mining and most cheap motherboards only support 6 GPU's. This is usually related to the number of pcie lanes that the board has, most of the time it's 8 pcie lanes. My research shows that the intel C242...

I agree with this ^^^ I think you might be thermally throttled or something like that. I have a dual cpu e5-2640v4 board with 160GB of ram( so 40 threads in a RAM disk) and it takes me 31 mins to make a plot.

I never have to adjust the turbo on my cpu in linux, the motherboard handles that.

Your swinging for the fences every time, change your threads to 16 are your hard drives in a raid array? What does your /etc/fstab look like?

I run exclusively on ubuntu with a dual e5-2640V4 with 192MB of ram - I have another system with an i9-9900k running with an nvme. I can tell you that reading all the posts, I don't think this stuff runs very well on windows. It was really designed for linux. The 256 buckets uses less RAM...

I don't think you have the command lines right there. use this guide https://www.truenas.com/community/resources/detailed-newcomers-guide-to-crossflashing-lsi-9211-9300-9305-9311-9400-94xx-hba-and-variants.54/

I have one of these sitting in my junk pile now, any time you put ANY different than HP card in one of those guys the fan speeds up to ludicrous speed. The included raid card ( i forget the name) is ok. I mean you aren't going to run freenas or do any ZFS on it, but other than that it was fine...

I have a question about this disk shelf, I pulled the second controller so that the shutup command would stick, also so that I didn’t have to deal with the multi path. But by me doing that did I limit myself to just 3gbs bandwidth? I am only using one sff8088 cable.

If you look at the code it's not doing anything interesting. Also I've checked my ports on the machine that's doing this work and it's not opening anything.

straight up NVMe's and on the old e5 just an old samsung 840 Pro SSD... Working on getting my raid0 disk array with 15 disks up again. This has been a fun learning lesson in reliability and redundancy.

Guys, I can generate a plot now on an old e5 first generation in under 3 hours. https://github.com/madMAx43v3r/chia-plotter The guy implemented the whole plotter in C++

Microcenter has WD external enclosure 8TB for $150

Hi, Not sure what the issue is, but I have a fully functional raidz1 ( yes i know) under ubuntu. Works fine, I can export and import it no problem. When I try to move it to a new trueNAS install I'm told that it is corrupt ( but it's not because when I move the disks back to ubuntu it's...

Well looking at the github repo his changes are performant, nothing strange or terrible. I'll throw this into my build in a docker container when I get some time tomorrow and give it a whirl. I think the big improvements and the reason you won't see this pulled into the mainline is that...

I haven't had any incompatibility with dac cables, I'm using some generic one, I have also used the cable matter's from amazon. I've also used an ethernet adapter module with no issue as well.

Just followed the old guides. I swear UEFI, just messes up everything. I'm sure it's great and I'm using it wrong, but damn.

This makes more sense, because it was only the SAS drives that were doing the duplication, because I guess they are dual ported. I pulled out the second EMM, mainly because the _shutup command wouldn't hold with both controllers. I suspect I would need another serial cable hooked up to the...

I solved the issue, I put the card in one of my old dell R510's and it flashed no problem. I think the key is to find something that doesn't have ANY EFI what so ever.

So i hooked up my (new to me) MD1220 with two controllers, and I hooked up my H200e flashed into IT mode on to the disk shelf. What I found interesting was that my hard drives were duplicated ( ie, /dev/sdf and /dev/sdg were both pointing to the same physical disk). Once I pulled out the...
