PCIe configuration problem

[shomy993]

So, i was wondering if i could fit samsung xp941 ssd in configuration with 4790k and gtx980 sli, due to 16 PCIe lanes the cpu supports and xp941 is PCIe ssd? Could the issue be solved with PLX motherboard and how would it impact overall gpu/ssd performance?

the PCI-E SSD run off the Z97 chipset aka the southbridge

 

the CPU is the one which manages the PCI-E lanes for the GPU

So i could potentially even add a sound card to this configuration without disturping GPU x8/x8 lanes configuration?

Thats how it's done natively for SATA E and M.2 but companies like ASRock do have some boards that pull directly from the cpu PCI-E lanes. I believe my Z97 board I use for my Pentium does for its M.2 PCI-E 3.0 x4 slot.

what is your mobo model?

yes it will not disrupt your PCI-E lanes for the GPU

Asrock Z97M OC Formula

If it PCI-E 2.0 x2 it won't for sure as that is figured in to the chipset at all time PCI-E 2.0 x4 is kinda option for M.2 as its not required for SATA E.

Only boards with DVI 3.0 would have PCI-E 3.0 coming off the chipset. This is currently limited to X99.

hmmm

 

i see this

 

- 1 x SATA Express 10 Gb/s Connector (shared with SATA3_4, SATA3_5 and M.2 Socket)*

- 1 x eSATA Connector, supports RAID (RAID 0, RAID 1, RAID 5, RAID 10, Intel^® Rapid Storage Technology 13 and Intel^® Smart Response Technology), NCQ, AHCI and Hot Plug

- 1 x M.2_SSD (NGFF) Socket 3, supports M.2 SATA3 6.0 Gb/s module and M.2 PCI Express module up to Gen2 x2 (10 Gb/s)

 

The M.2 Socket, SATA3_4, SATA3_5 and SATA Express share lanes. If either one of them is in use, the others will be disabled.

 

 

technically you can install the M.2 SSD

 

and it uses PCI-E Gen 2.0 x2 speeds

 

that is still ok speeds for PCI-E SSD to run as long it not from the SATA Gen 3 ports
