Hi Lawrence,
I have Teclast x98 PLUS II and I have the same problems than you. I had many troubles with Windows blue Screens and so on. I thought I was a problem of drivers, but I was wrong. The problem is that the RAM is defective.
Yesterday, I run a meatiest and I got more than 1000 errors! So now the only I could do it is send it back to China to be repaired, but I want to avoid that.
Could you explain me how to configure the BIOS to use only 2 GB of RAM?
Thank you very much!
