Unfortunately, I had to send all four building blocks due to a defect back to Amazon. There is, however, driven by a foreign company, no replacement shipment can be sent. So wait, sent back to items and money was refunded (paid in my case about vouchers), then order new products. Was a bit annoying.
The second shipment, which arrived today, seems to work perfectly. Have run an intensive memory test and found no error.
Conclusion:
As long as the memory is working just fine. But you should get defective RAM modules, an exchange is a bit time-consuming. If I had not paid for it on a coupon, I would have done the following: The set directly ordered 2 times. They would then have in the case of a defective storing work directly as replacement and could then end when things are going the other 4 memory resend.
Too bad that there is probably lately so many defective RAM modules. Had the problem already several times.
