Please check for x99m killer mobo hyper X dddr4 3000 32gb kit of 4 model number on asrock memory support list is HX430C15PBK4/32 http://www.asrock.com/mb/Intel/Fatal1ty%20X99M%20Killer/%3Fcat=Memory&Model=Fatal1ty%20X99M%20Killer&Vendor=HyperX" rel="nofollow - http://www.asrock.com/mb/Intel/Fatal1ty%20X99M%20Killer/%3Fcat=Memory&Model=Fatal1ty%20X99M%20Killer&Vendor=HyperX hyper x website does not match. hyper x website lists as HX430C15PB3K4/32 there is a "3" http://www.hyperxgaming.com/us/memory/predator-ddr4" rel="nofollow - http://www.hyperxgaming.com/us/memory/predator-ddr4 please double check thank you

I'm not sure what you're saying. It seems you are saying that HX430C15PBK4/32 is not a correct model number, is that right? If that is what you are saying, then what is this: http://www.kingston.com/dataSheets/HX430C15PBK4_32.pdf" rel="nofollow - http://www.kingston.com/dataSheets/HX430C15PBK4_32.pdf Kingston has many models of memory, the HX430C15PBK4/32 number might no longer be a current model, but it at least was used at one time. If you search on HX430C15PBK4/32, I get over ten pages of matches. If you check this page, it explains how to decode the Kingston memory model numbers, and you can see that the HX430C15PBK4/32 model does not have a revision number. It must be the first model of this type of memory: http://www.hyperxgaming.com/us/decoder" rel="nofollow - http://www.hyperxgaming.com/us/decoder The '3' in the model number you wrote about is the Revision 3 of this model of memory. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Hi I went to the kingston.com site and did a memory search with the part number HX430C15PBK4/32 Indeed it has been replaced by Replaced by HX430C15PB3K4/32 thanks for clarifying.

Generally when manufacturers create a new "revision" of a product it supports all the same features of it's predecessor, I would imagine the same goes for compatibility. This is the reason for a model "revision" vs simply releasing a new product. With RAM typically this is due to changing the actual RAM chips on the module's PCB, either to a newer version from the supplier or to a different brand with the same/similar specs. This is very common with RAM manufacturers. As stocks shift they find they need a new supply of RAM chips but the ones they were using for a particular model are no longer available etc. -------------

At least they are putting a revision number in the model number. But I'm not sure about the compatibility situation. Changing memory chips, which I agree is most likely the case, since most memory "manufactures" don't make their own memory chips, could cause incompatibility if they have different specs. That is the incompatibility of non-matched kits of memory. Two kits of what should be an otherwise identical memory model don't work together when used together in a board. In this case, the model numbers are just a bit different, but being different at all implies they should not be used together. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Agreed. No doubt that is exactly why they use the revision naming convention so as to differentiate between modules with different internals. The world makes sense again  So: 1. Revisions should be compatible with the same motherboards as earlier revisions. 2. Revisions are likely NOT compatible with other revisions when used together in dual channel mode (they may work but they are not certified to do so). -------------

http://www.kingston.com/dataSheets/HX430C15PB3K4_32.pdf above are the two data sheets for both. the second one is the newer revised one. if you look closely , there are differences. But are they significant? I am buying a package of 4 and not mixing with any others.

If you check the Memory Support List for your board, you will find the same model number of memory you are planning to use, the HX430C15PB3K4. http://www.asrock.com/mb/Intel/Fatal1ty%20X99M%20Killer/?cat=Memory The only difference between the entry in the Memory Support List and the kit you are buying is the capacity, you are getting a 32GB kit, the list has a 64GB kit, which has four 16GB DIMMs. If the 16GB DIMMs will work in your board, the kit with 8GB DIMMs will work in your board. Your memory is compatible with your board, according to the support list. ------------- http://valid.x86.fr/48rujh" rel="nofollow">
