" rel="nofollow - Hello, I've purchased recently new memory for my mobo from title, Samsung ECC 8GB. Earlier I had 2 x 8 Kingston, also ECC both works on 2133. Kingston are at A1 and B1 slots. When I put Samsung in C1 as it's recommended I get B0 error code (Error code for memory). If I put it anywhere else it doesn't work as well. But if I put it alone in A1 and remove Kingston memories it's working properly. Both memories are ECC. I'm running them with Xeon E5-2650 V3. Anyway can advice me what to do? Thanks. |

You now have two "kits' of differing memory. While they may be the same voltage, their timings are I'm certain different. Mixing memory as you have, most times, 99.99%, doesn't work, as you've discovered. |

" rel="nofollow - Yes, but is there some method to regulate memory clock, voltage etc. through BIOS or over some jumpers on board or I don't know...? Let say in 5 years I want to upgrade it and get additional RAM, how to find the exactly the same one? Now I can't return this Samsung ECC cause it's working, it's not damaged etc. If anyone can help please do so. :) |

Yet all memory is affected while setting via the BIOS. 5yrs out is a very long time. That isn't to say you won't find matching sticks/kit from the manufacturer but the likelihood is minimal. As far as returning that is left to the Seller. Most take a 15% restock fee to do so. Before l take leave of your thread, first I must say there is very very little chance you will make your two disparate kits/sticks to function. My suggestion would be to take the restocking fee hit and buy new memory in the capacity you need now and or the future. |

" rel="nofollow - I've bought it used for less money then in store, from private seller. It wouldn't be even a fair to ask him to take goods back cause memory is not damaged, working properly. Is this problem with pairing memory is something that all other mobos/manufacturers have? Mobo has some pretty adv features, also future features such as USB 3.1, new release of M.2 etc. and doesn't have option to set up each memory manually... Very bad. |

Unfortunately, yes it is. Do a Google search for/using "mixing memory" |

That I'll consider utterly incorrect, ie your comment of "Very bad." This mixing of memory that you say is "Very bad." has existed for the 30+yrs I have been computing and building and servicing computers for a living 10 of those years. I'm sorry you feel that way but you are misinformed and or having little experience in things concerning memory. I too learned the same way you are now. |

I had this problem earlier with registered and unregistered memory that had error correcting code (ECC), thinking that every ECC is by default registered. And I'm clear why this is not working. But here I think that problem are cycle latency or something else, I'm checking now, and if problem is CL then it would be normal to put that feature and control in BIOS. It would eliminate headache to many people like me. :) Or even better some auto check... Additional feature - to show valid code. As I understoon 60 or B0 code is general for memory. They should put additional codes for let say memory mismatch, memory error so that user knows what's a problem. Sorry for that "very bad", it's not very bad for sure, it's simple something not brilliant, and mobo itself is quite brilliant. I'm programmer since 286 era so I'm very well educated in hardware problems. Plus I was assembling computers back in '90s. :) And YES, I've double check compatibility before I bought and was sure it will fit, but it doesn't. :( |

Love your resume' Ivan. No programming here in my resume' though. As you've discovered they both are compatible, just not by mixing. To get those functions in the BIOS, I would assume wouldn't bed an easy feat. It'd be akin to alerting the User of a defective stick of memory and it's position. That hasn't happened either. |

The memory controller in your system is part of the CPU, as it is with all modern Intel processors. The mother board has only a secondary influence on the compatibility of the memory used with the CPU. The memory controller cannot work with different memory timings and other settings in different memory channels, unfortunately. It expects all the memory chips to be identical, and applies the same memory parameters to all the DIMMs in each channel. That is a limitation of the memory controller in the CPU, not the mother board. Think about this also; If the board cannot complete the POST procedures with both models of memory in the board at the same time, which is why you get the B0 POST code, how can you adjust the memory settings if you cannot get into the UEFI/BIOS to do that? What you could try to do, which most likely will not work, is to perform the following procedure: First put only the Kingston memory in the board. Then go into the UEFI/BIOS, and go to the DRAM Configuration screen. In that screen there is an option called DRAM Tweaker. Click on that option, and it will display the main memory timing settings for that memory. If you put a USB flash drive in a USB port on the board's IO panel, and press F12, a picture of the UEFI/BIOS screen will be saved on the USB flash drive. You can use the picture to know what the values for each parameter is. Then do the same thing with your Samsung memory. Only put it in the board, go to the DRAM Tweaker screen, and save the displayed memory timing settings in a picture on the USB flash drive. Then you can compare the timings for both sets of memory. You then must select the timings that are the highest values between both models, the "loosest" timings as it is called. Whatever model of memory that is, put that in the board, go into the UEFI/BIOS, and set the memory timings to those values. You may need to select the highest values from both memory models, if one model has a higher value for something than the other model has. After that, put the other memory model in the board, so both are in place. Then try to start the PC, and hope for the best. As I said, this probably won't work, unless you were very lucky and the Kingston memory uses Samsung memory chips. You can be successful sometimes mixing different models of memory from the same manufacture, but mixing memory from two different manufactures will usually never work. ------------- http://valid.x86.fr/48rujh" rel="nofollow">
