Have the 2x4 GB in conjunction with an Asrock B75 PRO3-M motherboard and an Intel CPU running G2020 (... had). So absolutely nothing overclock with or other high performance. WIN7 Index gave me a 7.2, and everything was stable and satisfactory.
I am particularly pleased that the RAM cooler have no "garden fence dimensions" and they are so well can easily block with a slightly larger-sized CPU fan (a Alpenföhn large Clockner lying in my case exatkt over the first Ramplatz the mainboard. Here fits the bolt but underneath!)
Durability: insufficient! -> A bolt defective after 6 months!
What I however really never experienced in my 20 years of "computer career" is that a RAM module breaks. I had previously bolt from various suppliers, from cheap to high quality. These bars were my first attempt at Corsair. Unfortunately failed ...
Especially annoying, that the prices for RAM rose again at the moment. Have 6 months ago paid 50 euros, currently the price is 70 euros.
Because Amazon customer service, and customer satisfaction takes more than serious, I can retounieren the RAM kit against purchase price and shipping cost refund. Maybe I'm - the only reason - start a second attempt with these bars.
