F@H using only 1 of 2 (identical) GPUs - is this expected?

[TyMarbut]

I'm relatively new to this so please forgive me if this is a common issue - a search didn't turn up anything directly relevant.

My F@H client, which has been running for several weeks, is now finally getting enough work to run the CPU and one of two identical GPUs (MSI 1070ti) pretty much flat out. The client interface lists both GPUs, but I'm not sure that I've ever seen it use the second GPU, even now that I'm running full bore on the CPU and GPU1.

So, the question: Is this expected, if the amount of work available is only enough for me to use the one GPU? That is, I assume it doesn't do any sort of load balancing between the GPUs. Would you expect different behavior than what I'm seeing? I'd love to contribute both GPUs and the power to run them if I could just get them both to perform work.

System specs:
OS: Windows 10
CPU: Ryzen 1950x
GPU: 2x MSi 1070ti "Duke"
RAM: 64GB @2666mhz

You can post your log per below, but I'm going to guess that you have two slots configured, one for the CPU and one for the GPU. If so, you can add a second GPU slot.

If you already have 3 slots, it's a fact that they work independently, so when the servers' bandwidth is limited you may not get assignments for all three concurrently.

Thanks Bruce! I will both check the logs (post if I can locate them) and learn about configuring >2 slots.

Meanwhile, though, if only 2 slots were configured, would you expect to still see all 3 devices listed on the client web interface? I ask because all 3 are (correctly) identified on the interface so maybe things are running just fine and there isn't enough available bandwidth/work.

Welcome to the F@H Forum TyMarbut,

Please note that you're missing a passkey which is recommenced to use for security reasons and bonus points: https://foldingathome.org/support/faq/points/passkey/

It seems that your system is correctly configured. There's a high demand for GPU WUs and the supply can't meet it yet. Work is underway to resolve that so just leave your client running and it will be assigned WUs when they are available. If you would like to double check, use GPU-Z to verify that the GPUs are being used correctly.
