XPG Z1 DDR4 2400MHz (PC4 19200) 16GB (2x8GB) Gaming Memory Modules, Silver (AX4U240038G16-DSZ1)

I have a cyberpower PC, and I bought these sticks to upgrade my current ADATA sticks. Having had problems in upgrading RAM before, I learned that the Clocking Latency is critical, or you will get the blue screen of death, reboots, and eventually you'll burn out your systems internal clocking mechanisms. My current white ADATA sticks installed in my system have a latency of 16-18-18, which is what these red sticks advertise as their CL. However, what was sent has a CL of 16-20-20. I returned the incorrect item with a description of exactly why, and they sent me exactly the same wrong sticks with the same latency of 16-20-20. I am now about to return the same product again for the second time. To all of you experiencing glitches after installation, I would strongly recommend you read the little white tag on your RAM sticks and see if the CL is identical to what you already have. A lot of the 5 star reviews here describe EXACTLY the problems that occur when incompatible RAM is installed. The seller may want to take a hard look at how many of these have gone out not as advertised, because they could be inadvertently wrecking PCs.

I have a CyberPowerPc I bought from here in November, and it came with 16 GB of this 2400 Hz RAM.I bought 2 more modules of the 2x8 to bring it up to 32 GB.Only one snag, stock RAM was in slots 1 and 3, so I put the new ones in slots 2 and 4.PC fired up but kept shutting off and rebootingThought the new RAM was bad, but I took out the old RAM and put the new ones in slots 1 and 3, and it booted to Windows.Shut it down and put the old RAM into slots 2 and 4, and it booted into Windows.Very curious why the new RAM would not work in slots 2 and 4, but glad I now have 32 FB of RAM.This RAM is a great deal if you can live without the RGB LED lighting which I could, as I have enough RGB already 😎

For Ryzen owners.. my kit's are Samsung die and while I'm running qty (4) sticks and will never hit close to the advertised speed due to the limitations of the "infinity fabric" and memory control of the ryzen chip... you can run it with very tight timings at slower speeds. You can run it at 14, 16,16, 16 with really tight sub timings at 2933 (for all 4 slots ) If you stick with just 2 slots - you can keep the low timings (or go 14, 14, 14, 14) and bump up the speed significantly. The 4133mhz advertised speed "future proofs" it a bit - if you switch cpu's or ryzen 3000 is better with higher frequency ram etc.I also have corsair c15 ram - (3000 rated) even running at only 2933mhz for the corsair and the adata - the adata performs a solid 10 percent faster - due to the tighter timings. You must set the timings manually - there will be no xmp profile for this speed. It's just quality ram that should work well in most systems (low timings at slower speeds in ryzen - fast speeds at c19 for intel )Update : I now have a 9900k intel system as well. With the increased voltage this set is successfully running over 4000mhz... at the same 14-16-16 timings of when it was the ryzen setups. (1700 and 2700x) If you loosen the timings to 16-18-18 you can kick it up to around 4400mhz. Amazing ram. I have confirmed that this was not only Samsung die but the desirable b-die as well. If you want to hit those low latencies at high frequencies.. you will have to go above the 1.4 voltage rating (it's not a problem with my motherboard/intel setup) If you stick with 1.4 volts you will have to use xmp for the 4133 rating (latency of 19-19-19). I don't see this kit available anymore - if you can not find it, try the gskill f4 series - ones with xmp's over 4133 + should get similar results.

Wow...great ram for the price...I'm not shur why this kit of 16gb at 3200mhz cas16 is as cheap as it is cuz it is NOT built cheap it is nice high quality heat spreaders on quality medium density dram chips from micron(the actual chip maker might vary from kit to kit so keep this in mind as if also had this same kit befor and it was populated with high density samsung but the performance was the same so as long as you dont mix and match them it will be fine), I'm am going to order a third set of these so I will possibly have a set of 32gb of the same die family(this is not an issue and is actually pritty standard for ram manufactures as I have about half a dozen kits of the corsair stuff and they do the exact same thing but the 2 that came in each kit were both the same exact specs so they effectively pre qualify these for packaging them as a kit same with Adata, wich in all honesty I didnt relize that's who made these when I first got them I just though they were some random generics that were cheap for a rig I'm putting together with some spare parts i had from my recent full server array upgrade but yep high quality adata moduals for the price of d grade low quality chinese knockoffs ya I'm sold...

Bought a new CPU which freed up a Ryzen 1600AF. Decided to upgrade my shop/garage PC with it and needed the cheapest 3200mhz kit I could find. At forty seven it was the cheapest kit out there besides trying to buy used. Paired it up with a used twenty three dollar B450 MSI Gaming Plus MATX. Updated firmware, set to XMP 3200mhz profile and works as it should. The red color also matches the color accents on the board & fans which is a bonus. Overkill garage PC but the i3 4330 was getting dated.

Got this pair on sale for 50 something bucks. Seated right in and mated with a Ryzen 5 first gen and 580RX GPU. OCd CPU to 3.8Ghz on stock V, and RAM to 3180Mhz with 5% voltage increase and it runs smoothly and constantly with no heat issues. I've run Davinci, Photoshop, premier, GW2, Destiny 2, Rocket League and GTA V at it all with intensive high settings and most games will run smoothly and eagerly at 60+ frames. No bottleneck here. Great Ram for a great price.

This memory does not run at 3200MHz natively. It requires that the XMP profile be activated in your computer's BIOS to run at that higher speed. However, it does it well. No issues with a new motherboard from Gigabyte, and the A520 chipset.

This RAM is not listed as compatible with my MSI x570 board. When I installed both sticks in the proper slots the DRAM debug light lit up and the system would not post. What I had to do:install 1 stick in the 4th slot (furthest from CPU) - system posted - enter BIOS - shows 8gb RAM running at 2666mhz - enable XMP - now shows running at 3600mhz(Here i inserted the other RAM stick and again - system would not post, so repeated steps with the other stick): - remove RAM stick, insert other stick in to the 4th slot - enter BIOS - shows 8gb RAM running at 2666mhz - enable XMP - now shows running at 3600mhzinserted both stick in slots 2 and 4 - now system is booting and showing the full 16gb dual channel at 3600mhzJust in case this happens to someone else during a build, maybe a 1 off situation.

What can I say, 32GB at a great price with a long term guarantee. No fancy RGB lights, no gimmicks and no overpricing!Update From 5 Stars to 1 Stars:I don't put my pc to sleep very oftend, so, without realizing that these RAM sticks were the source of my new problem. One day, I put my PC to sleep to wake it up with a black screen; the pc was running but keyboard rgb was off and screen was off. I did so many diagnostics, spent money thinking I needed to change components, to the point of chaning storage and installing a brand new windows with a different key. NOTHING WORKED... Suddenly, I get this massive bright lightbulb on top of my head. "MAYBE IF I TAKE OUT MY NEW RAM, AND PLACE THE OLD ONE BACK". Great success, the pc was able to fully boot from sleep mode. SMH... It was this damned RAM all along. All I wanted was to upgrade my pc for a few hundred $. Turns out I spent way more on other things that will be returned, including these faulty, ANNOYING AND TIME WASTING RAM stick o.O . Would I recommend anyone to buy these RAMs? Heck no, I would never want anyone to experience what I've experienced... Unless you're an experienced I.T person....

The best value right now in a reliable brand. If you cover the installation basics, you will be fine. So... Remember to install in slots A1 and B1 or A2 and B2. The first choice usually has black slots, though mine are grey. If you had two already in there, just use the same ones. When you restart, get into your bios before it fully boots. This may be 'del' or whatever button your motherboard requires. Find the memory in the bios and then find the XMP option. Turn it on, if it is not already. Choose profile 1, and save and exit. If all goes well, you will see the RAM operates at it's full potential (3200 MHz). If you see it operating around 1600 MHz in a program like CPU-Z, it is still just right, but showing the speed of one channel of a dual channel setup. Task Manager should show 3200 MHz. If all else fails, YouTube it. there are always folks that know more. But yeah, this RAM is exactly what it says it is. Good Stuff.

Pros:- Samsumg DRAM! (c-die)- A-XMP ready, no issues to get the 3200 mhz- Ryzen compatible (Ryzen 5 3600 & Ryzen 7 5800x)- MSI B450 Gaming Plus max / Tomahawk Max compatibleCons:- None yet.Installed these 2.x8 3200 Mhz RAM sticks on a new Ryzen 5 3600, B450 Gaming Plus Max build. Turned on A-XMP to get the full 3200 Mhz with no problem. The DRAM on these XPG Z1s are Samsung, C-die. Super fast. I have not tested these on memtest yet but will post updates later on. Well worth it!Edit (25 March 21): no issues with them still. I have also upgraded to Ryzen 7 5800x and they work good. I did a memtest86 overnight, and absolutely no errors! Will probably buy 2 more sticks to get a 4 rank with the new 5000 series ryzen when it goes on sale!

Tried to run this on an ASUS B350M-A CSM with a stock bios and no post. Had to find another stick that supported 2666 in order to update bios before it would start up. Once updated to latest bios, they posted fine and it was trivial to get them running at 3200mhz.Quick and so far prime 95 stable along side a Ryzen 3 1300x at 3.9ghz. They are Hynix chips. Be sure your board can support a minimum speed of 2933mhz as they don't seem to downclock well below that threshold (at least on the B350 chipset).
