PCI-e 3.0 card and 3.0 mobo running 2.0? - Page 2

why does that even show PCI-e 3.0 slot written on the motherboard when its a socket that no CPU supports it?

is this something i should call and complain to gigabyte and see what they have to say? i mean i screwed myself into thinking i bought a board i could expand on when all i did was limit myself to sandy bridge and pci 2.0

They don't false advertise. No offense, but seeing your previous posts I guess you are first time builder.

UD3H with IB will have PCI-E 3.0. The PCI-E lane switches on it can perfectly handle 3.0 speeds if CPU supports it. If SB is installed it will only provide 2.0. If both slots are used it will be X8/X8 at 2.0 with SB or X8/X8 at 3.0 with IB.

Both Ivy bridge and Sandy bridge CPUs use the same LGA1155 socket...

sorry mate, not a first time builder at all, just not my biggest hobby or priority in life

also, tigerdirects search feature is a little broken i search LGA1155 processors and it only showed sandy bridge


no offense taken, but you shouldnt assume it makes an ass|u|me , i do appreciate you trying to help, this forum is alot better than others so are the people on it

Essentially, the PCI-Express controller, the thing that actually communicates with the graphics card, is right on the CPU. If the CPU has a 2.0 controller, it can only work at 2.0 speeds, but if it has a 3.0 controller, it can work at 3.0 as well.

In addition, the actual board also has to support 3.0 going from the processor to the graphics card as well. There are "switches" which are enabled to run at full 3.0 speed from the CPU to the GPU, IF the CPU supports it.

Note that you will see little to no difference between 2.0 and 3.0 with a 7970 or 680 GTX. Like, 1% on average or 5% at the maximum. These cards simply do not saturate the bandwidth constantly to cause an issue running at lower speeds.

i linked something and asked if anyone knew if it was legitimate, noone ansewerd, however i edited the registry and its showing card running at 3.0 now on my SB smile.gif

ty for posting im going to run some benchmarks, not sure why or how but its running at 3.0, so either im missing something here or this is a "huge glitch"
