Hi, I have a asrock 970 pro3 r2 with a fx6300 (I think is quite generic config) I have 4x 8GB HX318C10F/8 Hyperx RAM. (1866MHz) The pc is rock solid with any of the two RAM, in any bank population config, but wont post if 4 (or 3) are inside. BIOS is the latest 2.40. No OC. Everything is AUTO. Any idea? |

First check that the RAM Voltage is set to the proper voltage. Some boards are known to undervolt them. Post back what you discover. We'll go from there with two more changes that should have you running 1866 on those sticks/CPU |

Hi, thanks for your reply. The voltage is set to AUTO...however I found a similar forum entry: http://www.tomshardware.co.uk/answers/id-2783786/upgrading-16gb-ram-32gb-ram-hyper-1866-fury-amd-fx8350-asrock-970-pro-motherboard-issue.html the solution is to set the memory timing manual to DDR3-1600 (instead of AUTO or 1866). With this the pc boots, and see all the 32GB RAM. What other options would you like to try? :) |

Ok. Are these 4 sticks from a 32GB(4x8GB) Kit? |

Here's where I'm going at by asking that. Whether they are 4 individual sticks or two 16GB(1x8GB) Kits, their programmed SPD and other must match. If they do not, odds are they will behave in the manner you describe. Using CPU-z, assuming they are actually two 16GB(2x8GB) Kits, place the two sticks that have consecutive serial number in and look in CPU-z that all their timing columns are the same. Record these numbers or capture a screen shot to refer back to. Now place the other two consecutive serialed sticks in and compare their SPD and other to the first sets. They should match exactly. If they don't that would indicate that either two consecutive serialed sticks will work by themselves, but not combined with the other two sticks. This is easily verified by doing the above. |

Actually, the were sold separately but all of them have the exact same part number: (I don't have windows, so just took the normal 'dmidecode' to see the part number, but all of them are the same): root@server:~# dmidecode |grep -A 7 DDR3 Type: DDR3 Type Detail: Synchronous Unbuffered (Unregistered) Speed: 1600 MHz Manufacturer: Kingston Serial Number: XX2C09XX Asset Tag: A1_AssetTagNum0 Part Number: KHX1866C10D3/8G Rank: 2 -- Type: DDR3 Type Detail: Synchronous Unbuffered (Unregistered) Speed: 1600 MHz Manufacturer: Kingston Serial Number: XX1B0BXX Asset Tag: A1_AssetTagNum1 Part Number: KHX1866C10D3/8G Rank: 2 -- Type: DDR3 Type Detail: Synchronous Unbuffered (Unregistered) Speed: 1600 MHz Manufacturer: Kingston Serial Number: XX2CF3XX Asset Tag: A1_AssetTagNum2 Part Number: KHX1866C10D3/8G Rank: 2 -- Type: DDR3 Type Detail: Synchronous Unbuffered (Unregistered) Speed: 1600 MHz Manufacturer: Kingston Serial Number: XX1BE8XX Asset Tag: A1_AssetTagNum3 Part Number: KHX1866C10D3/8G Rank: 2 I think, they must have the same capabilities, and same properties. But of course, I cannot be 100% sure about them. |

I was able to read the SPD also under linux with decode-dimms, and I must say that they are identical (except manufactoring date + serial number)

Ok. Here's what I'd like you to check and or correct. Below is what I was interested in. Well, ok enough now that I look at what you just posted. Bank 1 Module Manufacturer Kingston Manufacturing Location Code 0x07 Manufacturing Date 2015-W43 Assembly Serial Number 0xXX2C09XX Part Number KHX1866C10D3/8G Bank 2 Module Manufacturer Kingston Manufacturing Location Code 0x07 Manufacturing Date 2015-W43 Assembly Serial Number 0xXX2CF3XX Part Number KHX1866C10D3/8G Bank 3 Module Manufacturer Kingston Manufacturing Location Code 0x07 Manufacturing Date 2015-W33 Assembly Serial Number 0xXX1B0BXX Part Number KHX1866C10D3/8G Bank 4 Module Manufacturer Kingston Manufacturing Location Code 0x07 Manufacturing Date 2015-W33 Assembly Serial Number 0xXX1BE8XX Part Number KHX1866C10D3/8G Note in the above the highlighted RED Year-Week Codes of the four sticks. I'd like you to separate these out into pairs. 2015-W33 as one pair, 2015-W43 as another pair. Put a small piece of tape on the side of the heat spreader on one pair to distinguish them from the other pair. This gets them into as close of pairings as I'm aware as you didn't answer what these sticks came to you as. Just four loose sticks or as kits. I'm not familiar with how Linux enumerates memory Slot/Bank numbers so I'm asking you to bear with me as I'm proceeding how I know will determine/help us both, my way unfortunately. Put the W43 sticks in slots A1 and B1, with the W43 pair in A2 and B2. Side Note: Oh. Do these have XMP Profiles programmed on them, do you know? Ok, With them in the slots as I asked above go ahead and fire her up. Post back afterwards please and we'll continue from knowing what happens when you fire her up this way. |

Sorry. I just re-read. Came as individual sticks. Proceed as I asked above. |

Hi, first, thanks for your effort. I tested, but unfortunately it didn't help. I mean, the PC will not post. In any combination (with 2 pieces) it posts, and it shows correctly 1866 (if I set the timing to AUTO) But if all 4 banks are filled (in any order!) it wont posts, until I change the timing manually to 1600. I'm pretty sure now that the BIOS has some issues with this. |

Na. Not the BIOS. Let's take a run past our IMC voltage. BRB, gotta d/l and scan your MB manual. ... sec |

BIOS > OC Tweaker | CPU NB Voltage Bump the "CPU NB Voltage" up one step at a time, testing each time by attempting to boot. Your 6300 is rated at using two sticks at 1866. Four sticks of 8GB ea isputting a strain on the memory controller. Hence, I'm betting, why you can do four at 1600 but not higher. Give the above a shot,paying attention to your temps. You shouldn't need to go over 1.25v on the CPU NB Voltage . |

And for your furthering knowledge of this I should point out that the CPU/NB Voltage is the voltage applied to the IMC. |

first I raised the voltage to 1.2V but it didn't help. Neither 1.24V (and I didn't wanted to go further) btw I can just set even numbers (1.20,1.22,1.24 etc), so 1.25 is not an option, but imho 1.24 vs 1.25 shouldn't matter. Any other thoughts? |

Yea. But before saying I'd like to know if all your sticks have XMP Profiles programmed on them. Look in the BIOS to tell. EDITED due to my just waking up |

My first prio is the stability, so I won't risk to run at any reason on 1866. So I will stay on the 1600. But I would expect from Asrock to put a note in the manual that there is such kind of limitation in the AMD spec. I'm not saying that I wouldn't buy this once again, but I wouldn't spend extra on a 1866 RAM, if I know that it will not work. Thanks for your kind help/your time. |

If it helps, there isn't that much difference between 1600 and 1866 speed wise. Yea. It's AMD themselves that hides that nugget of "officially' supporting 2 sticks at 1866. It can be done, and with stability, but does require some tweaking to accomplish. Your current 4 sticks of 1866, running them at 1600 should net you some decent timings as you're running them at a reduced speed. Your OS will thank you for 32GB. Regardless. |

^This. The BIOS might show you the proper SPD values for a couple of different clock speeds when you select to set them manually, and these timings are supposed to be as official and stable as the timings for the 1866MHz speed, so using them is not really overclocking. By the way, if you need to buy RAM in the future, it is a good idea to buy them in kits. Even if the parts have the exact same parts number or even build date, it's not 100% sure they will work together. You can almost consider yourself lucky that all four modules work together. ------------- Ryzen 5 1500X, ASRock AB350M Pro4, 2x8 GB G.Skill Trident Z 3466CL16, Sapphire Pulse RX Vega56 8G HBM2, Corsair RM550x, Samsung 960 EVO SSD (NVMe) 250GB, Samsung 850 EVO SSD 500 GB, Windows 10 64-bit |
