I bought this memory because I thought OCZ would a manufacturer from which one can expect anything. In addition, the processing of my tie and the sentence liked "by hand tested" read also hopeful rise ... unfortunately the total disappointment. Unfortunately I can not tell you how the bars are if you are not even broken. The first delivery was a bolt in the bucket, causing blue screens churning. The replacement Delivered within 4 days later had not worked. Wahrscheilich it is up to the manufacturer's batch but the crap to return the stress repeatedly to Amazon, it is not worth buying this memory. Get congratulations to all the intact memory from OCZ, I have what I've now ordered by nem other manufacturers.
PS: Have the memory to 3 separate computers of friends and colleagues tested always the same.
