Add some voltage and they will not only overclock but get amazing timings. I was able to get CL 14 16 16 16 34 while running this 3200MHz kit at 3600MHz with 1.45Vdc and temps haven't gone past 35° ~ 36° C every time I've checked

Other than price and a few negative reviews relating to the pair not being matched, I personally have no "negative" opinions

I've never ran any G.Skill memory and I have always been a fanboy of Corsair due to their quality. The price for these vs G.Skill, I will be running G.Skill on my next build if benchmarks and industry reviews don't turn around.

Running Vengeance ram (8 gig X 2) for almost 2 years without issue, it seemed like a natural choice to get the same brand name when upgrading to 16 gig X 2.

Almost immediately after install, BSOD was a common multiple daily occurrence with a differed error code almost every time. Using 1 stick alone fixes nothing. Put my old ram back in and no issues.

No point bringing in my comp for service to diagnose. The cost is more than the Ram. Ill spend a little more money on something different.

Mixed manufacturers/lots. Both times I purchased, the two sticks were not paired and ran at different speeds.

Corsair can do better than to mix manufacturers. Individually, they will run at "stock". But running at the advertised 3600Mhz in pairs, constant crashing and memory issues in tests. Do not recommend unless you want to run it below the speed you paid for.

If you only need 32gb, this works just fine

If you want 64gb, be very careful in how you buy it

Buy this in person, so that you can check the box and make sure both are the same revision. Not at all the fault of memoryexpress since they only allow 1 per customer, but I bought two packs of this same mfg part number only to find that Corsair doesn't keep consistent manufacturers, sub-timings or rank type within the same part number. I got one pack of micron, one pack of samsung. They run just fine at 3200mhz individually, but wouldn't run stable at any speed beyond 2133 with both sets installed. Also, watch out for manufacturer QVLs that don't include revision numbers for Corsair RAM.
