Heciruam Posted September 10, 2018 Share Posted September 10, 2018 (edited) Hello everyone, So I build a system about a year ago but since I added a lot of services, I keep running out of resources a lot of times. I currently have a kaby lake i3 and want to just swap that out for an i7. I was wondering what I need to do here in terms of unraid. Will I have to reinstall unRAID or can I just power down, switch the CPUs and than boot? Thanks Edited September 10, 2018 by Heciruam Quote Link to comment
hitman2158 Posted September 10, 2018 Share Posted September 10, 2018 (edited) Are you sure that the i3 is the bottleneck? Or is it maybe not enough RAM? Before you buy a new CPU provide the experts here with the diagnostics. If you have to switch CPU: No need to reinstall anything. Just power down the system and switch off. Now remove the current CPU and install new CPU. Check twice or more to be sure that everything is okay (i recently crashed the mainboard of my gaming rig (changed from Intel to AMD), first time in DIY experience in the past 30 years). Now power on the system and be happy. Edited September 10, 2018 by hitman2158 just more explanation 1 Quote Link to comment
uldise Posted September 10, 2018 Share Posted September 10, 2018 what's a Motherboard model you have? do it supports i7? and according unRAID, no additional actions needed.. 1 Quote Link to comment

Before you buy a new CPU provide the experts here with the diagnostics. The thing is I am idling at around 60-70% CPU usage with all dockers running. When I copy files over to the array, I max out to 100% and all Dockers become unresponsive/unreachable. I do only have 8gb of ram and unraid seems to just waste it but I never had that as a bottleneck. I also don't have any VMs running. I believe it's the CPU. 3 hours ago, uldise said: what's a Motherboard model you have? do it supports i7? The MB supports the i7 and even overclocking. Thanks guys I will be looking for a used i7 then. Quote Link to comment

I usually check the utilization over the dashboard page: That seems to be unreliable. This is what the htop showed. So I'm guessing the CPU is not at it's limit but the RAM? Thank you Edited September 10, 2018 by Heciruam Quote Link to comment
uldise Posted September 10, 2018 Share Posted September 10, 2018 if you see 100% at GUI, then htop should show the same. but i think too that you are short of RAM - i see no "cached" color in Htop, but to use io effectively, Linux need some RAM for caching... 1 Quote Link to comment
tbonedude420 Posted September 11, 2018 Share Posted September 11, 2018 A new cpu wont hurt, should be as simple as taking out the old, and putting in the new. (what socket are you running? 1151? 2011? 2011-v3? What mobo? I have to agree with the others here though first, ram is king, and you sir seem to be running short. 'Part' of the high cpu usage, could be the fact the system is moving and caching memory to make more space available, and this takes cpu cycles to accomplish. 1 Quote Link to comment

I got the MSI Z270-A PRO Intel Z270 So.1151 Well Then I guess I have to go buy that overpriced ram. I was hoping to avoid this. At least ram will be cheaper than a new CPU. I will report back once I upgraded. Thanks for the help everyone! Quote Link to comment

Best advice I can give is use pcpartpicker.com and check prices from multiple vendors, and dont bother with memory frequency. Theres no visible difference to the average user when comparing ddr3 @ 1333 or ddr3 @ 2400. Same goes for ddr4. (ddr4 pushes the boundaries a bit, as its stock speed is 2133, and were already at last I checked 4500mhz) Quantity > quality > frequency. GBs > good brand > speed it runs at. 16gb of ddr3 is about 100$ right now, so depending on the amount you need, you can roughly calculate it. Quote Link to comment
Heciruam Posted September 11, 2018 Author Share Posted September 11, 2018 I believe my MB only supports ddr4. Also the already installed ram is ddr4 so I will have to go with that. I'll try another 8gb for now which should be around 60€, and than I'll see if the cpu is also a bottleneck. Cheers Quote Link to comment
Heciruam Posted September 13, 2018 Author Share Posted September 13, 2018 (edited) Ok I upgraded with additional 8gb of ram and everything works fine now. I guess the CPU upgrade can wait until I need it. Thanks again everybody! Edited September 13, 2018 by Heciruam Quote Link to comment
