HyperX Predator Black 128GB 3000MHz DDR4 CL15 DIMM (Kit of 8) XMP(HX430C15PB3K8/128)

I've had one of these for a year (2x8GB of the RGB variety) running at 3200 MHz on Ryzen 2700X with MSI B450 Pro Carbon. They have an automatic default speed of 2400 MHz and two XMP profiles with 2933 MHz and 3200 MHz.Added another one for 32 GB recently (one year later), Machine would not boot at 3200 MHz with 32 GB, not even POST. Swapped the sticks around trying all combinations and it worked in a few others. New sticks in slots A1/B1 and old ones in A2/B2 offer the highest speeds.4 sticks worked fine at 2400 MHz in any slot config. In one it worked at up to 2666 MHz and in two others it POSTed at 3200  but was unstable.  In the worst of the slot configs none of the XMP profiles worked. In the best all configs worked but only 2993 MHz was stable.Attempting to set custom timings I found (via Thaiphoon burner) that the two  sets (of the same model, bought a year apart) were in fact manufactured two years apart and had different RAM chips. In other words they were mismatched.Any combination of two sticks (from old and/or new sets) would work just fine at 3200 MHz but not all four.Ryzens inter core cluster CCX speeds are dependent on RAM speeds which means at lower RAM speeds some core to core to communication  will be slower. This speed is usually the physical RAM clockspeed (half of DDR frequency). Having said that desktop Ryzen's 2000s max rated RAM speeds is 2993 MHz and anything beyond that is overclocking. For 4 stick configs officially AMD only guarantees 2133 MHz.Currently running it at 2933 MHz via an XMP  profile and performance in CPU heavy benchmarks like Cinebench R15 are at around 99.8% of the 16GB 3200 MHz speed. Having said that speeds in apps like Photoshop and Audacity is much better with both apps starting up virtually instantly and running like greased lightning and Unreal Engine 4 doesn't slow down after a while especially after multiple undos. So real world performance for me at least is much better.The moral of the story being if multiple RAM kits are being paired together (even of the same make and model) they should probably be bought at the same time from the same vendor to ensure internal components tally and they can work at their maximum rated speeds.

Listen, this is like the most baller RAM you can get. It overclock well, it looks fabulous, and has great software built around the product. Unfortunately, if your ram sticks are not all adjacent to each other there can be serious issues with the RGB functionality. I slapped these into an X299 build, so there are two RAM sticks to the left of my CPU socket and two to the right. The gap between the two sets of Predators causes a delay, and often a malfunction in the RGB signals traveling between the lot. If you ran this same set in an AMD or 1151 socketted board it would be totally fine, but Threadripper, X299, and any other split-memory motherboard users beware. Your RGB light show isn't going to work correctly. That being said, this RAM is f***ing beautiful. I built a cyberpunk themed build so the delay actually added value to the overall look and I can't be anymore pleased. 4/5 stars simply because they don't work properly with all compatible build types but 69/5 stars for sex appeal. I've never seen anything so crisp and clear, in terms of presence inside if a PC case. If you have no other RGB products in your case, you won't need anything else to steal the stage. Bright, addressable, and quite cique in design, these sticks will fully complete any high end build.

I bought the HyperX Predator 32Gb 3600MHz memory RAM a year ago for my 1st PC build and the RAM worked like a charm. I was able to enable XMP and get the memory RAM to run at the rated 3600Mhz.Last week, I built my 2nd PC from scratch and ordered another HyperX Predator 32Gb 3600MHz memory RAM to install on the new PC. It worked fine at the default, i.e. slower 2600MHz, speed but when I enabled XMP in the BIOS to get the higher 3600MHz speed, my PC locked up. This RAM set would only ran at 2600MHz on my 2nd PC. So I tried to see if it would run at 3600MHz on my 1st PC. It would not so I requested an exchange from Amazon.The replacement memory RAM arrived today. I installed it on my 1st PC because the 2nd PC was not available at the time. Again, the memory ran fine at the slower default speed but not at the higher speed when XMP was enabled. I was expecting to have to return this memory RAM as well. But before I did that, I wanted to try it on the 2nd PC as soon as I could get to it (it's located someplace else).To my surprise, the memory worked fine on my 2nd PC at the rated 3600MHz speed with XMP enabled. Since this memory was intended for the 2nd PC anyway, I decided to keep it even if it didn't work with my 1st PC.Because of the finicky nature of the memory RAM depending on what hardware it is installed in, I decided to give this product 3 stars rather than the 5 I would have given it had it worked fine from the outset on both of my PCs at the rated higher speed. It's like a crap shoot. It might work but then, it might not! LOL

A lot of information out there talks about how it's easier to use 2 sticks of ram with AMD Ryzen CPUs than it is 4 sticks, and that was a bit of a concern. However, I'm pleasantly surprised that it all worked out. I did buy OLOy ram to test as well, but could not get it to work with their XMP profile nor using their timings. I messed with it for 2 hours before deciding to return the OLOy ram, and try the HyperX ram instead. This is the best bang for your buck, the heat sinks look and feel high quality, which wasn't true for the OLOy ram.In regards to my new setup, I have the X570 Taichi motherboard running the latest beta 2.73 bios. My 3950x didn't work with either of the XMP profiles, so I manually set the timings. According to Typhoon Burner, the sticks I got are Micron J Die, which are not found in the DRAM calculator. However, the Micron E/H die settings seem to be correct for J die as well.The official XMP profile is 16-18-18-36 at 1666 MHz, however I was able to tighten the timings and am running 14-17-17-34 at 1666 MHz, DRAM voltage 1.368 V, SOC 1.025 V, VDDG 0.950 V, VDDP 0.900 V.

Excelentes memorias, con una buena relación calidad-precio. 0 problemas en las ultimas semanas.

Works beautifully, no issues --- instant detection and set up.

Ich habe den 2666mhz Speicher. Ich hatte ihn vorher auf einen Z390, und da lief er absolut Genial. Ich habe ihn ohne Spannungserhöhung mit 16er Zeiten auf 3200mhz laufen gehabt, oder mit 18 Zeiten auif 3600. Jetzt läuft er auf ein AM4, und das sogar noch besser. absolut straffe Timings immo auf 3800 (!) mhz. Sehr straffe Zeiten auf 3200 mhz und sehr gute (17) auf 3600mhz. Übertaktungspotenzial ist der Hammer. Wie gesagt das alles ohne Spannungserhöhung (1.35v). Oder ich hatte ihn auf den XMP 2666mh mit 12er Zeiten auf 1.35v laufen gehabt.Bringt einfach Spaß mit den Speicher was man da alles Probieren kann :)Ich habe mir neuere GSkill Bestellt sowie Corsair Vengeance um evtl. noch mehr da raus zu holen. Beides 3600mhz Kits. Die sind nichts besser, aber teurer, im gegenteil die Timings sind schlechter als bei diesem Kit hier.Hatte schon etliche Kits zum Probieren und testen da, dieses hier Topt alle.Ich denke mal das er auch ohne murren die 4000mhz schafft, aber das macht bei AMD nur Sinn wenn man die IF mit übertaktet und das muß ich bei 3800mhz auch machen. Also läuft er immo auf 3600mhz um die IF auf Standart laufen zu lassen.TOP der Ram !

otima memória

Lucen de muy buena Calidad si no te importa el RGB. Las escogí ya que son las memorias más rápidas que acepta mi procesador, con la menor latencia a comparación de sus competidores por el mismo precio.
