I will soon be buying the Highpoint 71010A-1 PCIe adapter but my current Sapphire Dual-X 7970 is a 2.5 slot card so it cover slot 2.
My now dead HIS 7950 allowed access to most of slot 2 space.

I'm interested in buying a dual slot card that allows access to slot 2 for the Highpoint.

Any suggestions ?

Thanks in advance.

Use HighPoint on Slot-1 and GPU on Slot-2, use the smallest card in Slot-3, this way you don't starve the GPU of air.

If you use GPU on 1 and SSD7101A on 2, you will starve your GPU unless is a big one with a blower type cooler.

I think you mean smallest card in slot 4.

All dual slot wide card will block slot 3 in cMP. And if the GPU is single slot wide, when no need to worry about cooling and can be installed in slot 1 from the very beginning.

Hi everyone, I have an RX 580 4gb on my cMP 5.1, it will be better to get another one with 4GB and get dual gpus or I just get another one with 8 gbs? thanks. (2x rx580 4gb or 1 rx580 8gb)

What do you need the extra 4GB VRAM for?
How many monitors are you driving?
What resolution(s)?
What Metal/OpenCL/OpenGL applications are you using?

I used my mac for CAD rendering (Chief Architect), I don't know if I need the 4 or 8 vram but If I will like better performance on my mac and the rx580 4gb is cheaper then the 8gb

I'm looking at using the Highpoint 71010A-1 in slot 2 with a Vega Frontier Edition GPU in slot one. I see that the card covers about half of the fan on top of the GPU.

Does anyone run this configuration or something similar? Any issues in the long run doing this? Seems like the GPU is still getting enough air, but someone might have better insight.

Thanks. I could see the Radeon VII not really having issues due to having much more of the surface area of the GPU exposed, with the 3 fans and open side grates.

The Vega FE, like other reference cards, uses a single fan on top and that's it. That's what I'm concerned about. But so far, I've had no issues. *crosses fingers*
