Hi all,

I got an Asus GTX 970 Strix to run on the above setup. Note that Asus X53S and Asus K53SV use the same mainboard, so this should be replicable on the K53SV.

I have very limited understanding of eGPUs, so I used Display Driver Uninstaller and then installed the PE4C V3.0 and Setup 1.35 according to their standard instructions. In Setup 1.35, I set "PCI compaction -> Ignore dgpu", ran PCI compaction "except SATA etc.", then set the dgpu to "off" and ran the same PCI compaction again. I set the chainloader to mbr2, saved everything in startup.bat, and used BootIce to speed up the booting process, as described in the Setup 1.35 readme.

So far, everything seems to be working smoothly. I can even switch between the internal and external display without problems. Here are some benchmarks on the external display:

http://www.userbenchmark.com/UserRun/2857778

http://www.3dmark.com/3dm/18039963 (TimeSpy won't run for some reason)

I'd be happy to hear your feedback as to whether I did everything right and/or if I can further max out performance. For example, I don't quite understand the exact nature of the mPCIe link/generation/bandwidth used.

Thank you!

 PS: I'm not familiar with the naming conventions for these threads; admins feel free to change.

Have you checked to make sure the PCIe link speed is running Gen2? Run GPU-Z and check the info for "bus interface". It should say "@ x1 2.0". If it says "@ x1 1.1" then click the little question mark and run the render test to make sure it's not just idling at 1.1.

 

With the score you got it probably is running Gen2. I got a Fire Strike score of 6345 with a 960...

Android, any pictures of your gear you can share to bring your implementation to life?

Ensure you are running at Gen2 link speed as Plastixx mentions.

Disabling eGPU audio so you use the internal PC speaker only, using  to lock in 59/60Hz FPS and use of an external LCD pretty much maxes the narrow x1 2.0 link for video traffic.

Thanks!

It says PCIe x16 2.0 @ x1 2.0 - sometimes it falls back to 1.1 but when I click the question mark it goes back up to 2.0. I suppose that's good? Smile

While doing this (also sometimes while gaming) I get a strange faint screeching noise from the graphics card (or the adapter) btw. Could that be the infamous "coil whine" or something worse?

EDIT: Thanks nando! How do I disable eGPU audio? Pic attached Smile

Find your GTX970 "NVidia Audio" controller in Device Manager, right click and disable. Then the x1 2.0 link will be purely for video traffic.

Thank you! So far, everything is running fine. I will let you know if I have more questions.

By the way, I was thinking that an extender like the one attached would allow me to move the mPCIe interface outside of the laptop chassis, making the whole thing much more practical. I could leave the end of the ribbon cable dangling out and connect the adapter board as needed. Probably feasible for other laptops as well! Smile

Android, You have a PE4C 3.0, the best eGPU adapter for Gen2 signalling.

Each connector interface adds reflective noise, plus your hoping for good signalling down the ribbon cable. Gen1 link speed could certainly be viable. Gen2 more problematic. If your experimentation doesn't work then you always have the PE4C 3.0 fallback adapter.

I know, but it's just an extension - basically just a cable to let the mPCIe interface hang out of the laptop case, then attach PE4C V3.0 to that. At the moment the laptop has its bottom panel removed to reach the mPCIe, which is not very practical. So far it's just an idea though Smile

hello there. just cancelled an order of exp gdc 8.0, the supplier reported bsods at asus k53sd. since asus k53sd and asus k53sv are quite similar, I want to know, what and where to buy. and if it even possible to use the same setup at k53sd.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

Hi Eyre, and sorry for the late reply. I checked and it seems like K53SD is indeed very similar to K53SV, so I'm pretty sure you could get the very same procedure to work on your own setup! I was assured that PE4C V3.0 was the best eGPU adapter for this and it definitely worked very smoothly for me, I was very impressed.

You asked about where to buy - this might be your lucky day. Smile I'm thinking about selling my good-as-new adapter since I'm getting a new office laptop after all. If you're in the UK/EU you won't even have to pay customs charges like I did (most vendors are in US/China). Plus my hardware is tested working (both PE4C V3.0 + Dell DA-2 power supply). Just let me know if you are interested and I'll set up an Ebay auction for you!
