I'm reading reports about the BIOS.

Some machines won't boot with the newer GPUs. The 950 and the 1660 have about the same power use on power up so check with your PC's maker about a current BIOS and how to install.

would it be not working because i have legacy bios and not the uefi bios the 1660 runs on. if so, can the uefi bios be installed.

I would have looked that up but

You didn't supply which Dell you have. Yes you told me the motherboard but not which Dell so I could check out what BIOS is available. No big deal. Get your service tag and go find out what BIOS Dell is offering and check the manual.

Also, without a Dell model I can't see if anyone has more ideas on the web.

I can only do so much when working with limited details.

i have a dell inspiron 620. tag-d869hs1. i checked my tag and dell only has an a10 update for the legacy bios, nothing on uefi. i might be **** out of luck on this one unless someone else has a uefi bios.

You didn't tell.

If you had the latest BIOS. If not, get it up to date and re-test. tells us it will never work.

That said, I am running the 1060 GPU on an ancient HP d4999t as noted at:

Here's the 1660 vs 1060 results:

That's too close in GPU power so maybe the 1060 is the next move.

u didn't tell

the a10 bios from dell is their latest update so in my current configuration, looks like the 1060 would be my next move. i've been doing a little digging. would changing the motherboard with uefi bios work? an asus z77 mother is compatible with my dell setup and it runs uefi bios.

Changing the motherboard can be costly.

In fact more than a move to an even better 1070 as you would be out for a Windows 10 license (100 bucks) and maybe new RAM and more.

Your choice on which way to go.
