Patriot Viper Steel DDR4 RAM 32GB (2X16GB) 3600MHz CL18 1.35v UDIMM Desktop Gaming Memory Kit Compatible with XMP - PVS432G360C8K

Works at the advertised oc 3600mt/s, good fit with phantom spirit 120 cpu cooler, stable docp, no crashes, enough capacity for my workload.

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.

The compatibility and how it functions is very reliable. Fits perfectly in my computer very compatible. Does not crash and looks great

Perfect kit to complete the memory upgrade on my custom PC build! Sleek and low profile.

I'm pretty happy so far. I was running G.Skill Trident Z NEO rated at 3600mhz at rated timings, 16/19/19/19 and they happily played along with all my CPU overclocking set at XMP2. Didn't seem to have any issues running at 4000mhz either (but realistically not worth it with infinity fabric and looser timings, etc.). Wanted to see what 4400mhz looked like so I purchased these. I had also picked up some Crucial Ballistix 3600mhz at 16/18/18/18 for fun and need a few kits since I'm building another PC so more kits available is all the better.One thing I notice with all the reviews (for all memory) is that they seem to be all over the place and some folks don't seem to grasp that you need to enable the overclocking profile in the BIOS with all of these overclocked kits, regardless of brand. READ about memory before you go swapping it out and understand, at least just a little, before ripping on any new hardware? Please?Any which way I threw in the Crucials first...and before I did that, I reset the BIOS to optimized defaults with the existing memory. Reboot to desktop. Make sure everything is fine and then shut down. Disconnect your power. Swap kits. Reconnect power. Reboot. Motherboard will recognize the change and allow you to go into the BIOS. Once there just leave everything at default (other than checking to make sure memory is running at its lowest rating, usually 1033mhz). Boot to desktop. Run a test. Make sure things are functioning as they should. Check the RAM timings with CPU-Z or something similar.My Crucials defaulted to 1333 (2666), a little different than I'm used to, but in any case, they booted fine to desktop. Ran Cinebench without issue. Rebooted and set XMP2 in BIOS. Experienced a bit of a hiccup...hit my reset after about 45 seconds to a minute and it posted and went to desktop. The difference from running 16/19/19/19 to 16/18/18/18 was...not much :) I didn't do anything other than run 3Dmark and Cinebech. Since these had the hiccup just booting to the rated settings I didn't feel comfortable exploring and just reset to optimal and shut down.I'm running an MSI MAG X570S Tomahawk MAX WIFI board with an AMD 3700X, NZXT Kraken X63 AIO, Sapphire RX5700XT graphics card and an EVGA 750 G+ PSU. Not the top of the line by any stretch...but I think this MOBO is pretty darned good so far...Now to the actual review of the Patriots...did all of the above and booted to desktop. Ran a test or two. check. Rebooted and switched to XMP2. Rebooted and straight to desktop at 4400mhz at rated timings. No issues, no hiccups. Ran a few tests. No issues...other than 4400mhz doesn't do much! Looser timings at higher frequencies? I'm sure some gamers will have something to say but just for testing/benchmarks it ain't worth it so far as I can see for the moment and just initial impressions. Infinity Fabric at 1800...worth messing with? Perhaps when I get past initial "simplicity"...This particular BIOS has a memory overclock "try it" function so I've tried it. Worked my way from fairly loose 3600mhz timings to 14/14/14/14. 3600mhz with tight timings are working nicely at 1.45v. That's as far as I've gone tonight using some simple pre-sets and I'm very impressed with this kit so far.I've got an AMD 5800X to swap in but wanted to see what this memory does with my current CPU. I think I may dig a little deeper...though I do hate overclocking memory. When things do go bad it can get ugly. I think this memory kit is very good though so far and makes me want to go exploring. My Tridents didn't give me much confidence and certainly with my little hiccup on the new Crucials those don't have much future use other than trying in another motherboard.As of 12/20/2021 I'm very pleased with this kit. This is the 2X8, 16GB kit rated at 4400mhz. It will do the rated speed on my MOBO. Your mileage may vary. But honestly, the tighter timings at 3600mhz have me wanting to go exploring to see how tight these things can run and at what frequencies and what voltage. Don't know if they are the coveted Samsung B die or whatever, but they are Samsung. The G.Skill Trident Z NEOS's are Hynix and the Crucial Ballistix are Micron...for a hundred and 10 bucks delivered, these are my favorites. Now it's time to go to bed or crash my computer (:
