PCi Lanes for CPU's

Over the last several months I have picked up a new information bit form Asus "figure head" (IDK his name).

The PCi lanes are dictated by the CPU (of course, also Intel build I'm thinking of). and these PCI lanes are used for "everything" SATA connectors.

My question to you guys (I might need to place this somewhere else) is Can I have 4 hard drives with two GTX 970's in SLI with a Intel i7-4790k? + one optical drive bay for convenience.

or my information is wrong and I can do the go ahead with sli configurations with the CPU.

I had this same question a few weeks ago. Your chipset controls the SATA connectors, which would be your optical and hard drives. Connecting hard drives will not effect anything on the graphics side. The chipset is a microprocessor on all motherboards that is completely separate from the actual CPU. Note: double check that your mobo is SLI ready before buying it.

No problem! The chart is only for z97- features may vary by chipset. 99% of consumer motherboards' SATA ports are managed separately than the PCIe lanes.

The chipset itself has PCI lanes built into it for SATA and the rest of the I/O, but connects to the CPU through a different interface.

Typically, only the first x16 slot is physically wired to the CPU through PCI-E lanes. The other slots go through the chipset.

In reality, this makes no difference to performance and the chipset lanes are still seperate

CPU: AMD Ryzen 7 3700X - CPU Cooler: Deepcool Castle 240EX - Motherboard: MSI B450 GAMING PRO CARBON AC

RAM: 2 x 8GB Corsair Vengeance Pro RBG 3200MHz - GPU: MSI RTX 3080 GAMING X TRIO
