100% CPU load with 16GB RAM + eGPU

This topic is to continue X230 expresscard adressing (eGPU) discussion. The old topic is marked as solved and Lenovo doesn't pay any attention to it anymore while people keep complaing about 100% CPU load with more than 8GB RAM installed, i.e. 12GB, 16GB. I counted over ten Lenovo forum users having the same problem.

 

What has been tried so far:

* Memory diagnostic via F11at boot, all PASS

* Swapping memory sticks

* Trying various memory combinarions: 8 + 8, 8 + 4, 4 + 8

 

The problem seems to occure only for GPU cards with at leat 512MB RAM.

 

It would be great to hear that Lenovo is working on the fix.

x230 BIOS 2.02, Win8 Pro x64, i5-3320M, 16GB, Intel HD Graphics 4000.

Re: 100% CPU load with 16GB RAM + eGPU

Thanks for creating this new thread.

 

This problem is really really annoying for power users of X220/X230 series.

 

I use a X220 everyday at work with 4 screens connected through the docking station and the egpu.

 

As I use many virtual machines, I really need to upgrade my laptop with 16Go of RAM.

 

Hope Lenovo will get more attention to this new thread and provide some patch to correct this problem.

 

Regards

Re: 100% CPU load with 16GB RAM + eGPU

I have found a way to make this work on my machine. It is an x230t with 16GB ram and i7 processor and the latest BIOS. I am running Windows 8. My egpu setup is a Vidock 4 and a PNY Nvidia Quadro K2000 card with 2gb memory. My monitor is an LG29EA93. The start up sequence of Vidock, laptop and monitor is key to getting things to work. I boot the machine with the Vidock powered on and the express card inserted, BUT WITH THE MONITOR UNPLUGGED FROM THE VIDOCK. If the monitor is plugged in to DisplayPort during boot up my laptop will either not boot or if it does is unsuably slow and unresponsive. Once logged in to windows I hot plug the monitor into the Vidock port and then select the Windows 8 Extend display option. My screen will go off come back on go off again and finally after about 45 seconds the Nvidia driver (311.050) will load and I will have both displays functioning.

 

Hope this helps someone else.

Re: 100% CPU load with 16GB RAM + eGPU

Thanks for your advice,

 

I tried this morning at work but without success.

 

Note, I use a X220 with a docking station connected through a monitor with VGA.

 

I will try later without the docking station.

Re: 100% CPU load with 16GB RAM + eGPU

Unfortunately it didn't work for me. I tried without a docking station. I had only internal screen in use, nothing was connected to the laptop or eGPU. OS makes no difference, tested with Win8 x64 and Ubuntu 12.04 x64.

My setup: x230 + GTX 550Ti 1GB + PE4L-EC2C v2.1
x230 BIOS 2.02, Win8 Pro x64, i5-3320M, 16GB, Intel HD Graphics 4000.

No need to bump, too much time gone, Lenovo still has not give us any reply, ignoring means there will be no any attempts to solve the issue. IMHO
