Hello Experts,

I have this:
ASUS P8P67 EVO
2 x PCIe 2.0 x16 (x16 or dual x8) *1
1 x PCIe 2.0 x16 (x4 mode, black) *1
2 x PCIe 2.0 x1
2 x PCI
*1: The PCIe x16_3 slot shares bandwith with the PCIe x1_1 slot, PCIe x1_2 slot, ESATA3G & PESATA3G and USB3_34. The PCIe x16_3 runs at x1 mode by default for system resource optimization. (PCIe x1_2 will be disabled.)

Using Win7 64-bit

I would like to get this for my OS drive:
Samsung XP941 256GB AHCI PCIe 2.0 x4 M.2 SSD
And connect it to my motherboard using this:
Addonics ADM2PX4 PCIe 3.0 to M.2 SSD Adapter

Like to know these things:
1)Can my motherboard boot from PCIe?

2)Does it matter that the Addonics SSD adapter is PCIe 3.0 and my mobo's PCIe are 2.0?

3)Will my GPU or the Samsung M.2 SSD get throttled due to the motherboard's weird PCIe allocations?
 
1) Does your motherboard support UEFI BIOS? I don't think so. But I think you can still boot from a PCI-e SSD. You need UEFI to boot from M.2.
2) NO
3) Shouldn't if you use the 3rd PCI-e slot (x4). Disable all the other functions to get the most out of it (if you don't use them).
 
re the addonics w/xp941 in a PCIe 2.0 slot - i'm running a xp941 on an addonics PCIe M.2 card in a PCIe 2.0 card and have had no issues but it's going to want 4 lanes

when i ran mine in the M.2 slot which is 2 lanes on my mobo (asus z97m-plus, i saw read speeds of 770MB/s, write of 560 MB/s. When i moved to the addonics card, speeds jumped to 1050MB/s read, 800 write

JdotH,

I'm in exactly the same boat as you were back in April. I have an ASUS P8P67 Deluxe mobo and I'm wondering if I should try a PCIe adapter/M.2 combo as my boot drive or whether to play it safe and just get a SATA SSD given the age of the mobo. Did you go through with your upgrade and if so, how'd it go?

Additional quesitons:
1) Are you using the M.2 drive as your boot drive?
2) What OS did you go with?

Thanks!
