Patriot Viper Steel DDR4 RAM 16GB (1X16GB) 3200MHz CL16 UDIMM Desktop Gaming Memory Module – PVS416G320C6

Great price, beautiful, just works
Got them for my home server. The design is pretty beautiful, they have been operating 24/7 without any issues, the shielding actually does the job as it keeps them on nice temperature

DDR4 4400 MT/s -Superb, Especially for the Money
Before I get on to the specifics, please keep a few things in mind:1.) Forget about XMP, this is going to be manual tuning all the way. Probably even on an Intel platform.2.) If you just want to game or run some other app that requires fast memory with a minimum of hassle, this kit is not for you.3.) If you have a Ryzen platform, you probably won’t get useful performance out of this kit above 3800 MT/s.4.) Unless you have won the silicon lottery with your specific Ryzen CPU sample, even 3800 MT/s isn’t going to happen.5.) Likewise, even if you have a golden chip. you are going to need some luck with your motherboard.6.) You should expect to spend hours and hours tweaking and testing to get something usable. If that is not your idea of fun, this kit is not for you.Now, if you are undeterred by all of the above and are still interested in this kit, please read on.The kit comes in some rather plain packaging. Some people are unhappy with this, but I say that the plainer the packaging, the easier it is to recycle, so I am good there. I want my money to go to R&D, quality binned B-die chips, and QA. Not to marketing or packaging.Another complaint I hear about this kit is that the heat spreader is kind of cheap. This is fact. However, fancy heat spreaders are a bit of a scam. Even at high voltage and clock, you are not sinking much more than 5W of power into each stick, so whatever. I would prefer no heat spreader, same binned b-die, same quality PCB, and $1 less for the product. That being said, these sticks are a little on the tall side. Keep this in mind if there might be a clearance problem between your RAM and your tower cooler. If I wanted two kits of this, it would be an issue for me. But since I only want one and the slot nearest to the CPU is unoccupied, I have no clearance issue.I spent hours trying to get these to run at 3800 MT/s, to no avail. It is either the IMC inside my R5 3600XT or my motherboard (MSI B450 Pro Carbon WiFi), not the kit’s fault. I had no trouble at all running at 3733 MT/s, and I got timings that were even better than were suggested by DRAM Calculator for Ryzen. I used ‘fast’ settings, ‘A3/A2/B1′ for for PCB rev, and (of course) “Samsung B-die’ for memory type.I used the exact recommended primary, secondary, and tertiary timings. However, the termination resistances didn’t work for me; I went with the board’s defaults for those. After testing extensively at 15-15-15-15-30-1T and passing, I went for 14-14-14-14-28-1T. Those passed my quick testing and I am half way through the full battery of MemTest86 as I write this review. I am really, really comfortable with the looser settings and they are giving me everything I want.That being said, I am looking forward to hours and hours more fun tightening down the secondary and tertiary timings to not leave even one cycle of performance on the floor. If I get bored with that, I might be forced to game instead of benching -)For $125 I got a kit of the highest possible bin of B-die memory and it suits me perfectly. You can buy more expensive kits if you need the name “G.Skill” printed on the side, and still more expensive kits if you want that plus RGB. As for me, I don’t care about anything except the bin quality and quality time at my bench. I figure I saved somewhere between $50 and $100 making this choice as opposed to the best bin of TridentZ RGB and lost exactly zero performance doing it. That is going to be my down payment on a shiny new R5 5600X as soon as I can get my sweaty little hands on one.Now, if you are still planning on buying these, I have a few quick tips for you to save some time:1.) Have your bootable USB stick with MemTest86 on it ready before your package arrives.2.) Use the same stick to save your OC profiles, unless your mobo will retain your profiles after clearing CMOS3.) Plan on testing outside of your case unless you have a clear CMOS button on your back panel.4.) For initial testing, cut the address range down to 4G and skip the last two tests, and do two passes instead of four. this will save you a ton of time.5.) Once you have settings you like, run all tests, full address range over night before using them 24/7.6.) Start at DRAM voltage of 1.5V. Once you have settings you like, you can experiment with cutting some voltage, if you like. This won’t hurt anything and will save you some time upfront.7.) Enjoy the ride. If this doesn’t sound fun, just get a 3600 CL16 kit for $80, boot it in XMP and call it a day.I hope this helps and thank you for reading.

Great price memory for the right setup.
Patriot Viper Steel DDR4 16GB (2 x 8GB) 3733MHz. This is the kit I’m reviewing in case it doesn’t show up on the review title. Some reviews have kits from the same series with different speeds mixed in with these reviews.Pros,1. Comes with heat sinks.2. DDR4 3733 CL17 speeds of course.3. Overclockable and underclockable.4. A grey gun metal finish in my opinion would looks good with a lot of motherboards.5. The price I paid.6. Worked fine on my fine MSI Z570 Gaming Edge WIFI motherboard with an April 2020 BIOS update.Cons,1. Not easy to install into memory slots on my motherboard and I’m sure other people would have the same issue.2. May not run at rated speed depending on the motherboard you use. I read a few reviews from people using older AM4 and LGA 1151 sockets that wouldn’t run the XMP(or AMD equivalent) values so some people had to manual set their timings and/or underclock the memory.3. If running an older B450 or X470 motherboard from AMD you may want to make sure you use the latest BIOS for best memory stability.4. Not really a con, but more of a personal preference for some people and the lack of this may bother them. It’s not an RGB set, but that doesn’t bother me.5. For best performance you may want to tweak your settings. For example you may want to lower your memory speed to 3600 and tighten your CL from 17 to 16 for better latency. This is not easy to do and you want to study some videos on YouTube and read some memory timing forums.Overall they worked for me and I’m not saying they’ll work for everyone. I read some reviews that were good and some that were bad, but most of the bad ones were from using these memory sticks with Intel and older not updated AMD AM4 motherboards. Since the price was good and I’m a Prime member it would have be easy for me to return these if they didn’t work so with the modern Z570 motherboard a have with the latest BIOS I felt it wasn’t much of a gamble.

First of all, this is literally the best B-Die for the price. If you are buying this to enable XMP, do yourself a favour and find something else. This is NOT a plug-and-play except for very few Intel systems. I own a Ryzen 5 5600X. Using AGESA 1.2.0.0 BIOS. Was able to get great, tight timings with both 3600 MHz CL14 and 3866 MHz CL16. Currently prefer 3866 MHz / 1933 FCLK. Ryzen loves both speed and latency, especially higher frequencies. Some people are able to hit 4000 MHz but I couldn’t (silicon lottery, BIOS, etc). Anything above 3866 MHz would produce WHEA Errors due to AMD Infinity Fabric limits (it can change with different BIOS).Performance: Went from a 3200 MHz CL16 XMP RAM to this Viper Steel 4400. Let me tell you that my Warzone lows gained 40+ FPS at 1440p! This is one of the biggest upgrades I’ve ever come across. RAM is very underrated. XMP has pretty long and high timings. It was worth it so much to learn to adjust timings manually.I provided screenshots for both profiles (every system is different, do not expect the exact same values to work flawlessly. Test with TestMem5 anta777’s config for stability).I HIGHLY recommend GitHub’s DDR4 OC Guide. I had no clue where to start and what to do. It’s ALL you need for the most part. The Reddit’s “r/Overclocking” community has been a great help too! RAM tuning is not hard, just time consuming.My latest profiles’ voltages:* 3600 MHz 14-13-13-27 : VDIMM 1.45V / VSOC 1.1 / CLDO VDDP 0.9 / VDDG CCD 0.95 / VDDG IOD 0.975* 3866 MHz 16-15-13-28 : VDIMM 1.46V / VSOC 1.1125 / CLDO VDDP 0.91 / VDDG CCD 0.95 / VDDG IOD 0.98
