2 video cards, NOT SLI, trying to solve downclock issue
My son has a new PC with an EVGA 2080 Super FTW3+ Ultra video card. He runs 3 monitors. 2 of them are 60Hz, and 1 of them is 144Hhz. When all 3 monitors are plugged in, at idle, the Nvidia 2080Super is running at 1,650Mhz and not downclocking. If I disconnect either of his 60Hz monitors, leaving him with a 144Hz and a single 60hz, the video card WILL downclock to 300Mhz at idle. If I take his 144Hz monitor and set it to 60hz and he runs all 3 monitors, the video card WILL downlock to 300Mhz at idle.
I don't like the 2080Super always running at full clocks for following reasons
- Power usage. When the 2080super is at 300Mhz, idle power usage is 20w. When the 2080 super is at 1,650, at idle power usage is 48w.
- Heat. When the 2080 super is at 300Mhz, idle temps are about 35C. When the 2080 super is at 1,650, at idle, temps are about 50C.
Solving the problem has a few options
- Have him run on 2 monitors only, 1 at 144Hz and 1 at 60Hz. But who wants to go back to 2 monitors when you have had 3 for years?
- See if adding an additional 144Hz monitor and removing a 60Hz monitor works right. I'm thinking that with 2 at 144Hz and 1 at 60hz, it's going to be the same issue I am seeing with 2 at 60Hz and 1 at 144Hz.
- I am considering buying something like the MSI GeForceGT710 PCIe video card for $50, and installing this into his PC as well. We can move 1 of the 60Hz monitors over to the secondary video card, leaving a single 60hz and single 144hz on the 2080 super. This should in theory allow the 2080 super to downclock at idle again just like it does now when I unplug one of the 60Hz monitors.
Any major concerns with adding a single cheapo video card by Nvidia, simply to run 1 of the monitors?
