Pros: Easy to setup. Currently have this set installed on a Asrock Z170 OC formula mobo with a 6600k. As of today on gskills website they have this ram not being compatible with the mobo im using. But the ram works just fine, XMP profile easily enabled in bios. Ram works very well. Make sure you update your bios.
Other Thoughts: Passed memtest and windows memory diagnostic tool, no errors.READ FULL REVIEW
Pros: These are short low profile sticks. They are not tall and flashy like other ram modules brands. Currently using these in a Asrock Extreme 4 mobo with a 5820k @4.5. Xmp profile easily enabled in bios. These modules work really well.
Other Thoughts: Tested Aida 64 memory and cache benchmark.
Stock xmp profile for 2666mhz is 13-14-14-39 CR2.

I have been running the lower timings 12-13-13-38 CR1 2666mhz for the past few weeks and has been rock solid.
I tryed to overclock the ram to see if they could go faster but the mobo or memory controller on the cpu cant handle anything higher than 2666 mhz at the moment.
I do alot of gaming and some video rendering and recording stuff. I have thrown everything at these modules and they have been a very good purchase for me.
Pros: Runs cool, runs quiet, runs up to 1525mhz. Voltage is unlocked with newest updated Firestorm utility, 1.31volts checked at card with multi-meter. Boost straigh out of box is 1405mhz.
Temps stay low around 52C, fan speed at 62% at 1525mhz while running Folding@home.
Cons: Firestorm utility is mostly broken. Zotac knows this.
I use this card to run Folding@home and nothing more. When clocked at 1525mhz while folding, gpu power usage is around 50 to 60%, gpu voltage is 1.24volts checked with multi-meter. If I try to go to 1535mhz, the power usage throttles to 30% and stays there. That is the bios at work there, Zotac implemented a protection into the bios so it would not go above 1525 mhz. I can actually max out voltage and it will not change. I can run the card all the way up to 1620mhz before I actually get an all out driver crash. So this card is capable of hitting 1600mhz but it won't because power usage protection kicks in above 1525mhz.
Card will also coil whine sometimes if I get a work unit that makes the gpu usage go up to 99% Most work units though has the gpu usage hovering around 50% usage.
Other Thoughts: This card has alot of potential, but is being held back by the bios. I have modded many different bios for this card to try to get around the gpu power throttling issue and have not found an answer yet.
Printed on the back of box the card came in it says''Total Unlocked Access''. Well, that is far from the truth, I have proved it. This card is just screaming to be woke up, and can't.
Zotac is a good company, they have alot of good things going for them over there, they put alot of real great good people working for them. Zotac knows if they do unlock this card, then they run the risk of increased rma's.
A 1525 mhz overclock for this card is actually pretty good, I should not be complaining, but I know I own a product that has more performance left inside of it. And I would like to have access to it when I need it. If Zotac does not release a fixed bios for this then I will be selling this card at the end of the month and picking up something better on black friday.
