System Error Message

I suggest you try it out and if you get resource errors try disabling some of the devices connected by PCIe. If you look in device manager and sort by resource you can see what device is sharing the lane with another.

whether or not you need the bandwidth really depends on your code. If you have a lot of communication between CPU and GPU than you do need bandwidth and low latency, otherwise if you're just loading code onto the GPU, running it with no CPU communication and than getting the end result <strike>after a few hours than you do not need to do setup 1.x since even 1 lane of PCIe would be enough.</strike>. It also depends on how much data you send when communicating between CPU and GPU.<strike> If you arent using more than 300MB/s worth of data between them than you dont need setup 1.x.</strike>

I have played games before using 1 lane of PCIE and a GTX 580 from my thinkpad and it does work fine for some games that only use the GPU as an output device and preloads things to the GPU but i also had the monitor connected to the GPU as well. I have connected 2 nvidia GPUs to my thinkpad before (1 through dock with Extender and added PSU) giving me a total of 3 nvidia GPUs on my laptop. You can read about my experience on the thinkpad forum.

Also if you have an nvidia GPU already in the laptop you dont need an external monitor to display things since you can set it to display on another GPU while rendering work is done on another. This feature is only available between nvidia GPUs but i dont know if it is only limited to quadro GPUs and openGL but can be coded for in openGL.

Since you have IGP i suggest you get the adapter, PSU and GPU and use nvidia optimus. <strike>You dont need compaction if your program doesnt need the bandwidth. You also dont really need a DSDT override with nvidia GPUs since they work with less memory resources.</strike> expresscard is plug and play even for GPUs but only if you arent running your display through them but you must use the remove device option from windows (appears as vga compatible device) or you will get bluescreen. I have not had any resource problems before connecting nvidia GPUs to other laptops that dont use AMD GPUs.

You could try replacing the thermal paste for the CPU and GPU of your laptop and get a cooling pad. Unless there is a bottleneck somewhere GPUs will always run at full capacity so even playing an old game can give you hundreds of fps and a full GPU usage. AA and very high resolution is always considered demanding in processing and vram while AF, texture quality and detail dont really take up much resource.

Different games are designed differently, and some use tricks to look good at lower performance while some are designed badly that end up using too much resources. Some big titles are designed to use a lot more resource to encourage you to buy better hardware.

assuming neither are disabled they are both active but only one is used at a time because even bluetooth has mac address. If you look at the physical address when connecting you will only see one hardware address under details.

set options to use less vram but you can increase processing elements. Lower view distance as well. How much vram do you have?

im using asus ac68u with merlin firmware and the wifi signal covers a 3 story house very well. ive had other routers that could use openwrt but i couldnt overclock the cpu. merlin firmware has openvpn support. I still use mikrotik as my main router though and im thinking of getting their 32 cloud core router. Mikrotik routerOS is amazing though not open sourced. i ended up using my shiny AC68U as a wifi AP and even merlin firmware disables many options in that mode and my tp-link 1034nd openwrt as a print/scan server.

dont go with the Engenius, they have very high failure rates and about my college used to be full of them. About 70% of them failed in 2 years. If you can increase transmission power than you can use a better antenna or directional ones if your router has multiple antennas. There are better wifi APs like Ubiquiti. If you want to reuse old wifi routers make sure you turn of their dhcp function and wire them together for better performance instead of using it as a wireless repeater. You should have the wireless SSID on both routers to be the same but if possible, set different channels for them that do not overlap or you can leave the channels on auto if you have too many neighbours.

I have many more systems but its so much detail

some games dont work on sli or crossfire but if you arent playing those games (some new big titles are like that) than the question is budget and a processing vs memory question. GTX 670 has 2GB or vram while a gtx 780ti has 3GB. New games and high res use more vram while 2x gtx 670 will not double the amout of vram.

egpu with nvidia gpus if you already have one in the system or only integrated is easy as long as there are enough pcie lanes in the chipset it is connected to. Ive only encountered resource problems with AMD cards. nvidia ones use a lot less resource. If your expresscard is connected to the southbridge it may be difficult or slower.

hi, just registered and annoyed with the 5 post rule just to download a single file.
