HP ELITEBOOK 2560P GRAPHICS DRIVERS DRIVERS

Likely due to having two different drivers for the AMD cards. My 2570P doesn't have such silly allocation so maybe they fixed it in all later Elitebooks? Contact HP requesting they modify the bios so that Motherboard resource allocates into the 0xF0000000 range so the 0xD0000000 256MB block can be used for eGPU 32-bit pci-e allocation. This is the tried-and-trued solution used when encounter limits with 32-bit PCI allocation.ДЈ. Perform a DSDT override allowing allocation into 36/64-bit PCI config space. Though I've explained previously that for your system that lacks an active iGPU, a AMD card will perform better.Дў. These NVidia cards require 128MB+64MB+16MB or 128MB+32MB+16MB respectively. Get a NVidia GTX560Ti or GTX660+ instead of an AMD card that can allocate around that problem Motherboard resource. Really not intelligent at all for our purposes.ДЎ.

HP ELITEBOOK 2560P GRAPHICS DRIVERS WINDOWS

The 4 256MB windows above 3GB (TOLUD) are summarized as:Д xD0000000 (Motherboard preventing using this as a 256MB contiguous block)Д ењЋ0000000 (pciex - reserved, can't be used)ДЄ HP BIOS engineer plonked that Motherboard resource preventing the use of that window for your AMD dGPU.

You have 2 AMD GPUs both of which require 256MB contiguous PCI config space at a 256MB boundary, but there is only 1 one available that is already hosting your dGPU. With your TOLUD=3GB there are 4 256MB windows available. Unfortunately there's an issue with HP's BIOS. Please see here as requested: diagДevice has the following resources reserved: I have tried every permutation of pci compaction but cannot get it to work successfully, even with all the other PCI devices disabled. When I shutdown I get a BSOD with 'PROCESS_HAS_LOCKED_PAGES'

It also shows a PCI Express standard root port with error 12, I am guessing this is related. So when I load Setup 1.x the PCI compaction fails unless I select 36bit or higher, however when I boot into Windows like this I get either normal windows with the eGPU not detected, or a 16-bit display and device manager shows the eGPU 'working' but the dGPU is not present and I cannot change the resolution.

An AMD HD7870, with it's need for a larger 256MB contiguous PCI config space, required Setup 1.x's PCI compaction to be performed for those systems to be able to host that video card without incurring an error 12 against the card in Device Manager.ДЁ560P is highly likely to also incur error 12 with that being the corrective solution. IBLarry, my experience with the Sandy/Ivy Bridge Elitebooks (2560P/2570P) find that a NVidia GTX560Ti/GTX660 card can work without needing Setup 1.x.
