First, we do not specify which chip we use in our Overclocking modules. We specify the clock speed, latency values, and voltage that the modules are tested and guaranteed to operate at. What really matters to customers is what speed the modules can run at, so that's naturally how we specify the modules. But we can use any chip that meets our specifications. Our reasoning for this is simple. When you buy a Super Talent module you're not just buying a bunch of chips on a PCB; you're buying all the testing that we put into the module, and our quality guarantee -- we stand behind the product. The vast majority of our OC modules are capable of running well over their rated specs.
Also, to offer the best possible price and availability we need to be able to qualify multiple chip sources for each module (when possible). We work tirelessly to drive our costs down and improve our availability and lead-times for each product, but we need the flexibility to use more than one chip brand to be competitive. Of course our competitors do the same thing -- they use a variety of chip vendors for their 800MHz parts to drive costs down.
For customers who want the exceptional performance of Micron D9, they can buy our top speed grade modules since currently we use only Micron D9 on our 1000MHz kits. Of course these Micron D9 based modules are considerably more expensive and have very long lead times, so it's not a good volume production product. If you're interested in testing our 1000MHz kits I'm sure we can support you.
If you experienced any issues with our 800MHz kits, I can't imagine why since we haven't seen any quality issues with these kits. Our test process in production is very intensive, and like I said, the majority of our 800MHz kits can run at nearly 900MHz. We'll be glad to replace any bad kit you may have.
You can contact me any time for help with questions or issues. I'll be glad to help in any way I can.

Vlt. bei CL7... 
Denk aber, es könnten auch Mosel-Chips drunter sein. Die packen auch 800Mhz bei cl4 und dann 1000Mhz bei cl5. Das wäre schon mehr Glück.
