The Vengeance 1600 CL9 RAM has been detected in my system (further information below) no problems with the right timing.
The workmanship is top quality and the feel is also very good. Various color designs and each design is the right to its mainboard if desired.
Performance and / or temperature differences to Vengeance 1600 RAM with high heat spreader can not be detected.
In my system, a combination of 2x 4GB Vengeance runs 1600 low profile and 2x 4GB Vengeance 1600 with normal Heatspreaders. What's amazing that I can leave the Ram running even with 16 GB with 1600MHz and sharp 9-9-9-24T timings. No blue screens or crashes.
Necessary both were low profile RAMSŽs by an oversized CPU coolers, whose fans have obscured the fourth RAM bank if I had RAM modules used with high heat spreader.
Furthermore I tested the RAM with MemTest64 where a data throughput of just under 23GB / s was measured. This value confirms the good impression of RAMŽs. The Windows Experience Index certifies the RAM 7.8, both 8GB verbautem memory as well as 16GB.
Here's the system:
AMD FX6100 @ 4,0GHz
Alpenföhn GroߎClockner
Gigabyte 970A-UD3
XFX Radeon HD 6870 DF
WD Caviar Blue 1TB
AeroCool VX-E
Conclusion: Fast and reliable RAM with excellent price / performance ratio, strong buy recommendation!
