KingstonHyper X Plug n Play 4 GB Kit (2x2GB Modules) 1600MHz DDR3 Desktop Memory 4 Dual Channel Kit (PC3 12800) 240-Pin SDRAM KHX1600C9D3P1K2/4G

got this ram for my OptiPlex 780 and now using in Dell Precision T15001st, I bought 4 modules and one of them failed.thank you to amazon, they sent me replacement without charge in 2days.worked great. you can notice the speed difference once you install it.it did down clock to 1066 with OptiPlex 780. since that board can only clock ram to 1066.so I got Dell Precision T1500 with i7 and yes, it will adjust clock speed to 1333.RAM is also XMP profile ready.a lot of rams are out there but if you are looking for something compatible yet want some performance out of it, I recommend this ram.works very well with OEM PCs

How can I review RAM without doing lots of measurements and benchmark testing ?I was just looking for 2 sticks of good RAM to replace a single 4Gb (10333) stick in order to enable Dual Channel mode. This made a huge difference to the speed and responsiveness of my PC !Looks good although when it's installed that is meaningless as you can't see it, it's not black, it's a satin grey colour with silver shiny markings if that's important to you.The important thing is that it has made a huge difference to O/S load times and program load times, Rendering pictures is about 10 times quicker ! It made the whole system much snappier although it is not only a faster memory speed, it also allows me to enable dual channel.

Ram ottime, velocissime, molto solide e senza problemi di collegamento.Si scaldano veramente poco e si adattano molto bene.Consiglio l'acquisto a tutti.
