This is great performance ram as it has been raved about by many. XMP runs at 3200 CL 16. Price to performance value is exceptional and ram sits low (standard ram size). This set has the famous Micron Rev E Die which is known to have great overclock room (YMMV based on your CPU and Motherboard). I picked it up on the Amazon deal for $91 but originally purchased it for the $115 price tag before that which was still worth it. The deal just sweetened it that much more with saving big on this set. I have mine overclocked at 3733 CL16 with safe settings on my Ryzen 5 3600. This ram can definitely go higher in frequency but mine won't boot past 3800 as it won't hit 1900 FCLK. I am not an expert overclocker so I have not tried different work arounds and messed with the timings but there is a lot of info out there of people getting great CAS Latency and Timings. As I've seen and heard, this ram seems to be compatible and perform well on any motherboard without any performance drop offs compared to some brands. 100% recommend this ram even when its not on sale.

I had 4 sticks of 8gb Crucial Ballistix @2666mhz with XMP enabled. This ram was solid, but I wanted a little more. I knew it was possible the gains could end up being small, but I had the money, so I went for it. My computer is an IBuyPower 'Enthusiast'(Yes, I plan on upgrading the psu and graphics eventually) that I use for day trading stocks. The computer was already pretty solid out of the box, especially for only $499, but what I liked was that the ASRock motherboard B450M-ibw (proprietary to IBuyPower, but same as a B450M/ac) and AMD platform that I thought would be a fairly solid starting point with which to upgrade as I came across more funds. The first thing I did was go from the stock 8gb of ram to Crucial 8x2. This helped a bit, but needed some help, so I upgraded to a Ryzen 5 3600. Already excellent gains and speed (It came with a Ryzen 3 2400g). I overclocked the Ryzen 5 to 4.2ghz @ 1.4v, which proved to be nice and stable, but I didn’t like how high the voltage was, which is not needed and really only causes heat, so I ended up at 1.375v. I then bought 2 more of 8gb ram by Crucial for 32gb total, 8x4gb at the stock speed of 2666mhz. This was fine, but it really didn't help much bc I was still at the stock speed of 2666, so in essence, I could tell, and feel, that it could be improved upon. I eventually did away with the 4x8 setup @2666 and went with this kit at 3200mhz, 16x2, with XMP enabled. I tried messing with timings to see if I could achieve CL15 or CL14, but every time I saved bios settings and rebooted, it kept throwing away XMP as well as my cpu overclock and rebooting everything to auto. So essentially, what I discovered is that at least with a Ryzen 5 3600 and an ASRock B450M-ibw(same as B450M/ac, just different bios), these Crucial Ballistix either don't like to be overclocked passed their stock XMP overclock settings, or the motherboard/bios doesn't like it. I have a feeling it's the ram that doesn't like it. Full specs are: Ryzen 5 3600 overclocked to 4200ghz @ 1.400volts Crucial 32gb(16x2) 3200mhz CL16 with XMP enabled. So right now with this setup, my best Cinebench rating is 1825, which I noticed beats out quite a few Ryzen 7 setups listed on Cinebench. I still have the stock PSU and graphics card which I'm itching to upgrade, but I haven't decided if I'm going to add 2 more 16x2 sticks for a total of 64gb. I know most activities won't benefit, but some will, so there's that. Crucial is definitely solid kit. There's a reason they are as reputable as they are. Hope all that helps. ** Edit (as of 04/25/2020): I’ve upgraded to 64gb of ram, 16x4 with xmp enabled @3200mhz. If this makes sense, overall it’s not faster per se, but does feel ‘smoother’. Everything feels effortless, almost like the cpu accesses to ram when it needs to for help, which is rare, but seems to ‘know it’s there when needed’, if you will. I’ve upgraded the cpu to an EVGA 750w Gold, the graphics card is now an RTX 2060 Super and I’ve put a Noctua U12A cpu cooler on the cpu which has allowed me to squeeze the overclocking to 4.3 @ 1.375. I’ve upgraded the intake and exhaust fans to Noctua F12’s and this thing is not only stable as mountain, but quiet as a mouse. I have an air purifier in my room that is louder than this thing. Anyway, just some tweaks I thought I’d add. Well worth it. Ram is excellent, can’t go wrong. *** Edit #2 (as of 10/5/2021): I still have 64gb of ram, but I've bought all white modules that are 3000mhz cas latency 15 (CL15). Full Specs now are: - Ryzen 9 3900x w/ Noctua NH-U12a for the cpu cooler (Using Noctua's NT-H2 Thermal Paste) - RTX 2070 Super - 64gb Crucial Ballistix 3000mhz CL15 overclocked to 3466mhz - Corsair case with Kaze Flex case fans - B450m/IBW (Proprietary iBuyPower Motherboard made by AsRock (Closest AsRock has is the B450m/ac and no one seems to have a clue what the difference between the two are even though they look identical to my eyes). I keep pushing its limits and it hasn't failed me. If I upgrade it'll be to an x570 Taichi as I'm already comfortable with how AsRock's bios is laid out. - Seasonic 750w Platinum PSU - Samsung 970 Evo Plus NVME with Archgon M.2 2280 Heatsink(purchased here on Amazon). Actually everything was purchased on Amazon. Everything is running like butter. My Cinebench Score is over 7500 now with my Ryzen 9 overclocked to 4.4ghz. Please be aware the Cinebench is not a good indicator of your ram timings and mhz speed being stable as Cinebench is more CPU intensive. So anyway, My previous 64gigs of ram I could not for the life of me get timings tighter. They were 3200mhz at CL16. I wanted CL15 or CL14 as this is better for production since I don't actually game(hence why so much ram). I was able to get the old ram to 3466mhz with Infiniti fabric at 1733 no problem, however. In comes the 3000mhz CL15. It's all white now instead of a mix of red and black even though the specs were the same on both the black and red sticks. I popped in the new all white ram, got myself into the bios and something interesting happened. I did not need to touch that 3466mhz overclock. It immediately registered the same, but held the 15-16-16-35 timings. This is a win as I rarely experience happy surprises of that nature when dealing with overclocking scenarios. Boy was I a happy camper. I was completely prepared to have to set the new ram's XMP profile and attempt to again boost the frequency and Infiniti fabric, but in fact, the old memory's setting held in the bios. I've checked the performance tab in task manager and sure enough, it says the ram is running at 3466mhz and Ryzen Master confirms Infiniti fabric is at 1733. I'm not going to push it any further as I'm still on a B450m motherboardnow extremely happy with how everything is running.

I was buying a Dell G5 gaming desktop and wanted 32Gb of memory in it. It was more expensive to order it from Dell with 32Gb installed than it was to order it with 16Gb installed (2 x 8Gb) and buy a 16Gb upgrade (2 x 8Gb) from Crucial. As soon as the new computer came in, I went straight to Crucial's website and...out of stock (frowny face). When I checked Amazon, the exact product I wanted was available, and for $5.00 less than directly from Crucial ($64.99 vs $69.99). Installation was a snap (see what I did there?). It literally just clicks into the slot. When I turned on the computer's power, the memory was immediately recognized by the bios, and then by Windows. No problems, no glitches, no nothing. Perfect.

I bought this at about $112 and it was a steal. I bought 2 of the 32GB sets of 3200mhz C16 for a total of 4 sticks and 64GB. Running 4 sticks, I got it to clock stable at 3600mhz (@1.42V) which would be good with 2 sticks but this was wth 4 sticks. I also tested some T-Force Vulcan ram 3200 C16 and it ran at XMP but it wouldn't clock any higher than what it was rated for with just two sticks. Sadly this Balistix ram is discontinued I'm told and the price has skyrocketed. Hopefully the price will come back down at some point. Glad I bought when I did because I'm not going to upgrade to DDR5 until it becomes economical. Other benefits of the Balistix ram is it's fairly low profile and also narrow profile while having a good heft to the heat spreader. 1 Downside, think they are single rank, that's why I splurged for 4 sticks and 64GB. At today's price? I would probably be looking for 2 times 16GB dual rank kit. Crucial Ballistix laptop ram has also been good in my experience and is still a fair buy right now. I like the brand in ram.

I'll try to keep it short lol. At 1.35v, 3200mhz (32 gig kit) and the default timings CL15-16-16-34, I would get errors in memtest and stability issues in Windows but it would always boot. If I dropped down to 3000mhz with the same timings there were no errors or iissues after 10 memtest86 passes. I haven't really tried tuning these sticks much yet so I might update this review but 3000mhz at CL15 will get you better gaming performance than 3400mhz CL16. So I don't really have much to complain about. I do want to test 3100mhz with the same timings tomorrow and see if memtest86 throws any errors... I know I could probably get it up to 3600mhz with different timings but I'm really happy with the timings I have already. It's a fantastic value for the money. The only thing I would change is the heatsinks. Id make them slightly larger. Of course if you're staying between 3000mhz and 3600mhz they are fine, I just like a tiny bit of wiggle room when it comes to thermals. Still I'd buy these again even if I can't get the speed any higher while also staying at CL15.
