Hello,

Just received my PE4L 2.1b + E2C2 for my Thinkpad X230 and Gigabyte GTX760. All done well under Win7, no issues, but I'm concerned with low benchmark on 3DMARK 11 Adv.Ed. -- performs just P5650 (default settings), max FPS about 40 in 1st test.

BIOS is updated to the latest from Lenovo website, no additional settings were made.

I tried SW1 / SW2 in different positions - no difference, unpluging from device manager and back - no difference.

To bring life to an old thread, another person stated low benchmarks due to not having the battery attached, which could also happen if the battery is low. Appears this is due to having a 65-watt power adapter, which cannot provide enough power on it's own, resulting in under-clocking. Solution is to make sure the battery is full or use a 90-watt adapter. That and using a gtx760 is overkill for an egpu due to the restricted bandwidth - lower end cards are supposedly more efficient. Also Lenovo just released a new bios which may improve the performance, and if so, please confirm for other x230 owners.

Earlier this month, Lenovo released a new bios for the X230T, version 2.60. Does anyone know if this new bios will allow better egpu implementation? There were problems with memory allocation, effecting TOLUD and limiting ram to one 8GB stick instead of two. Anyways, thought I'd give a heads up about the new bios. Maybe someone can confirm if the issues are fixed now?

[edit] Well, did the update and checked device manager - still at 3.5GB TOLUD for me.
