MP 1,1-5,1 HELP!!! Sluggish Mac Pro 5,1

[pablomanda]

HELP! My Mac is getting kind of sluggish while I'm working with it. It's been a couple of months already. I do only mail stuff on Safari, after about 15 minutes, then it becomes very slow creating or deleting tabs on Safari, even when I click on the Mac logo, it takes like 1 sec to respond. I tried doing a clean install, but didn't help. Tested the RAMs with Memtest86 with 100% pass. Repasted thermal paste of the CPUs and Northbridge (Mastergel Maker). I also blowed the dust with canned air. GPU temp is around 40C. Same behavior happens with or without OpenCore. Does anybody know what's causing this weird behavior? BTW I'm booting from a NVMe SSD (TRIM enabled and formatted in APFS), maybe the SSD is faulty? Could the PRAM battery influence in this? I don't have one installed because the holder is broken. Restart can solve the problem but reappears after a while.

Here is the video of what's happening:

Specs:
Mac Pro 4,1 flashed 5,1
Dual X5677
24 GB memory
Vega 56
macOS 10.14.6

Any help will be appreciated!!

I gather from that 3,5 in your About This Mac, that you're using OpenCore. If that's the case, check if the sluggishness goes away by booting natively. Maybe there is an issue with your configuration.

Yes, I'm was using Opencore. Now I've disable Opencore and the problem doesn't go away

So something else is causing the sluggishness. I'm not sure about the missing battery... Did you try to rule out your current Mojave system by preparing a test clean install?

Have you run Blackmagic Disk Speed Test on your NVMe drive?

Last week I did a clean install of Mojave then immediately installed Opencore. You say I should try again to make a clean install and boot natively (without Opencore)?

Yes, I'm getting read/write around 1000 MB/s. The SSD is Inland Premium 256GB on a cheap NVMe adapter. How can I check the SSD health? SMART status says not supported.

You say it's a 'cheap' adapter.
Is the NVMe drive overheating?
Install Mac OS on a sata ssd, your only using Safari, an NVMe drive will be no faster than a sata, which will run much cooler.
Also does your Windows system run slow too.....?

Macs Fan Control reports 35C on the NVMe drive. Will try to install clean Mojave in a sata ssd. Windows 10 runs smoothly on a sata ssd. Thanks!

Sounds like an issue with the NVMe (or adapter), if the win install is not sluggish .......

UPDATE: For those who are experiencing this problem, I went from Mojave to Catalina 2 weeks ago, and now the Mac is running smoothly.
