I was also able to post at 3333 MHz, but this gives me instability issues. I may try tweaking the voltages to see if I can squeeze a little more out of them, but overall I feel lucky to get what most others have not been able to do.
Edit: I am happily able to get these to run stably at 3333 MHz, although I had to reduce the timings by a notch. I ran memtest86 for 7 hours with no errors. Here are my parameters:
DRAM = 1.35v, SOC = 1.25v, Timings = 18/19/19/38
I would of actually been ok with that, dispite the "bait and switch", had it actually worked at 3733MHz. Sadly it does not on my new ASRock Z390 Taichi Utimate.I would not even boot at anything above 3500MHz. At 340MHz it booted into windows but BOSDed when running a benchmark. At 3300 it booted and finished the benchmark, but a memory error popped-up as I was shutting down.
Two stars because of the price even if you have to down clock it, but not running at advertised speeds, timings and the "bait and switch" make me not want to trust Patriot again or buy their products in the future.
Hopefully those buying in 2019 will have better results than I. THose that where able to get kits with Samsung chips, consider yourselves fortunate.
*Edit* After around 4 months one stick failed. I contacted support the next day and was redirected to the RMA department. They sent an email explaining exactly what to do and I sent both sticks off, per the instructions. It took a couple days to get there and they immediately sent out a new kit which took a couple days to get to me. All in all it was a very pleasant RMA experience. I have no complaints and it was resolved quicker than I thought it would be. Definitely look into getting yourself a kit if you're in the market, they seem to look out for the customer, and not just the dollar signs.
I haven't gamed with it yet, but I'm sure there will be no issues. If anything my old GPU is the bottleneck of my system. I'm just holding out for prices to drop on a new one.
I have been burned in the past with unstable RAM in various motherboards, but this is a great match if you want to go the Ryzen route and use ASRock's board.

It's also frustrating that a supposedly top-end kit even in 2019 only has JEDEC (plug and play) compatibility with DDR4-2133. Anything above that requires manual tuning or use of XMP, which either way is an overclock. All modern high-end processors support DDR4-2666 plug and play.
The redemption from one star to two is that Patriot include a second XMP profile at 3466, a nice touch for high-speed kits that I wish more manufacturers bothered with as many memory controllers can't OC to hit 3733. If the kit was advertised correctly that would be great. It would be nice if they tuned the DDR4-3466 profile though, as it is the timings are just copied from the 3733 profile.
So far I have struggled for stability @3466Mhz on my B450M using pretty loose timings and the top end of the supported voltage. This stuff does post easily and isnt too much hassle to get running, but dont expect tight timings.
This ram now works with my R5 3600 and a Asus x470 Prime Pro motherboard, at XMP profile speed(3733Mhz).
Im very pleased with the performance as it maxes out the infinity fabric speed on ryzen 3600 so I know I'm getting the best performance. These were £50 more expensive when I purchased and seem like a great purchase for the price now.
I expected these ram sticks to be Samsung B-die as other websites had listed this set as being so, but it uses Hynix CJR memory chips instead.
I can run it at 3133Mhz at tight CL 14 but any further than that and I get memory errors, even if I loosen timings to CL 16.
Im sure it would be great for use with more capable processors, it may improve when BIOS updates increase RAM compatibility with Ryzen but if your expecting Samsung B-die memory sort of speeds you best look at a different set of sticks.
Luckily, I've always got half a dozen builds on the go at once, and found that it worked perfectly in a Gigabyte B450-DSC 3H, running at full speed. I tried this with a few different AM4 CPUs and APUs and found that it did make a decent improvement in performance over other 2400MHz that I tried.
The RAM also looks good, but as usual, because it's really tall, can sometimes be a pain if you've got RAM slots close to a fat CPU cooler.
Overall, totally happy with this purchase and the performance of the RAM, but always check your compatibility with your motherboard (especially if you're using Asrock as I *always* seem to find that they're the brand that has issues with RAM compatibility, even with Intel builds).
So, would totally recommend with the caveats mentioned above.
Good price but the controller on chip is a cheaper variant from the same model and serial number sold 6 months ago.
Sad really wanted 32gb ram 4 sticks at 3200mhz and it only goes up to 2933 perhaps if the memory was single rank as before it would be better.
Just an update. After bios update and CPU micro code update it now only runs at 2800mhz without error on mem test.
Still a nice looking bit of kit at the right price that is.
