[SOLVED] I7 2600k gpu things

[willismatt5]

I have an i72600k with an Asus p8z68-v lx

And I got a sweet deal on two rx 570 in the box the question is I know the motherboard supports crossfire but intel says the cpu has one 16x lane

The manual will usually have the info you require; but from the looks of things the information regarding the PCIe slots is rather poor: https://www.asus.com/Motherboards/P8Z68V_LX/HelpDesk_Manual/

Usually the x16 slot's bandwidth will be shared in a multi graphics card set up, so if using two it might be split x8/x8.

x8/x8. would be good enough for pair of those GPUs providing that MB supports crossfire but I question doing it at all. Very few games support it nowadays and gains are minimal when they do.

In the question of the motherboard supporting it ir does in fact but in the case of the gain I don’t really know what do you you expect someone to do with two identical cards

Well in my case I think I’ll spring for a new rx 580 or 90 it’s only like 20 bucks more

Used obviously

Take care when you look for used cards like that, they were very popular with Bitcoin miners and if used for a year, fans may be pretty worn out. Some have dual BIOS, one set for mining and other for games, or have BIOS updated for mining.

Yes I aware of this and with the card I plan to get it has quick disconnect fans

Expansion Slots
1 x PCIe 2.0 x16 (blue) *1
1 x PCIe 2.0 x16 (x4 mode, black) *1

That board will run x16 in 1 slot, x4 in the other slot, as long as pcie x1(1) is unpopulated, or it'll run in x2 mode as bandwidth is shared between the 2nd x16 and (1) x1.

Same layout as my p8z77-v LE. Very common on budget boards, you'd need an upgraded version like the p8z68-V or p8z68-V Pro to get x16/x8/x4 instead of the x16/x4/x2

 

[willismatt5]

Well I plan to just buy a single more powerful gpu that why the thread is solved

Good idea. Crossfire was sketchy even when it was somewhat popular, it never had good support, and has even less now since DX12 (Windows 10 native) is mgpu base, no CF or SLI support at all.
