Riser 2 card for CPU2 only?

Question

Hi,

I have what I hope is a simple question but I'm not able to confirm it on the Dell website.

I'm wanting to use a 2nd PCIe card in my R650xs which requires an additional riser card, does this require a 2nd CPU for it to work?

The card would go in PCIe slot 3 which would connect to the motherboard via the riser 2 connector, is there anyway for this to work with a single CPU?

Thanks

Neon_Ghost,

Unfortunately if you're looking to install a card via slot 3 using any riser 2 variant, the system requires a second CPU be installed. With only CPU 1 installed, slot 3 will either be inactive or disabled based on the riser and configuration chosen. For a single-CPU system, you are limited to slot 1 (on riser 1) and slot 3 is unavailable in all configurations without CPU 2

Let me know if this helps.
