I have an ASRock 970 Pro3 R2.0 I have had this motherboard for about 6 months with 2x4Gb Ram sticks in slots 1&3 working just fine. I wanted to upgrade my computer by adding 2 more 4Gb Ram sticks into slots 2&4 however when I boot up my computer, my monitors don't even respond. I've checked that the Ram works by replacing the original Ram that I have had for a while with the new Ram and my computer boots just fine. I've also tried booting up my computer with Ram in slots 2&4 and that also works just fine. I'm not too sure how to fix this issue so any help would be greatly appreciated.

| Try lowering your ram to the lowest speed in the bios before installing the extra 2 sticks and then working your way up to the max speed. 4 sticks wont be stable at the same speed as 2 sticks. |

Can you please post all your hardware specs, i.e. CPU model, GPU, PSU, UEFI version, etc. Post all details you know about the RAM you're trying to get working, e.g. timings, exact model, etc. ------------- 1700X ZP-B1 (stock); X370 Taichi (UEFI 3.10); 16GB F4-3200C14-8GFX XMP; 256GB 960 EVO; RX 580 NITRO+ 8GB |

well write it in these boxes ............. the issue is more than likey as hinted above and that being the ram needs different settings when using 4 sticks BUT we cant help without knowing more info primary things like what cpu your using,and what ram make and type ------------- [url=https://valid.x86.fr/jpg250]  [/url]3800X, powercolor reddevil vega64, gskill tridentz3866, taichix370, evga750watt gold |

Buying 'the same' RAM twice, i.e. 2 times 4GB doesn't mean all 4 sticks are the same. Very often the same model and brand uses totally different dies for what would otherwise appear 'same' RAM. Both RAMs should work OK when only one of them is installed. Running them both at the same time and speed is a tough luck. Start with updating your BIOS and clearing the CMOS after all RAM sticks are inserted. Then try lowering the CAS for starters, bump the voltages a bit. Problem is that I have no clue what voltage and OC option your mobo has. Maybe you'll need a bump in the NB voltage too, maybe some others. Depends. ------------- 1700X ZP-B1 (stock); X370 Taichi (UEFI 3.10); 16GB F4-3200C14-8GFX XMP; 256GB 960 EVO; RX 580 NITRO+ 8GB |

we had a very very similar problem within the last few weeks which i recall vaugely end result was the fx wont run 4 sticks at 1866 i think im sure i found an amd tech sheet stating 1600mhz max with 4 rams i think the guy the other day was even forced to use 1333 to get it stable (and to get it to boot had to use 2 sticks ,set ram speed and then install the other 2 sticks) this is from memory ,best idea is to search the threads from the last few weeks ------------- [url=https://valid.x86.fr/jpg250] [/url]3800X, powercolor reddevil vega64, gskill tridentz3866, taichix370, evga750watt gold |

The maximum supported stock speeds for RAM with an FX processor are: Available slots / Used slots / Single rank / Dual rank / Mixed single and dual rank / Clock speed 2 / 2 / x / x / x / 1866 MHz 4 / 2 / x / x / x / 1600 MHz 4 / 4 / x / - / - / 1600 MHz 4 / 4 / - / x / x / 1333 MHz Overclocking may be possible even with four memory modules, but as zlobster already stated, there's no guarantee that two different kits of RAM work together at all, even if it's the same exact model. I'd suggest you follow the method datonyb recalled: Use two of the modules so that you are able to boot into BIOS and set the speed to 1333 MHz. Then add the two other modules and see if the system boots. If it doesn't, you probably need to start increasing CPU-NB and RAM voltages. Maybe 1.25V for the CPU-NB to start with. If it doesn't work, then possibly 1.3V before increasing RAM voltage to 1.6V. You can probably find some tips in the AMD FX performance tuning guide ( https://www.amd.com/Documents/AMD_FX_Performance_Tuning_Guide.pdf" rel="nofollow - https://www.amd.com/Documents/AMD_FX_Performance_Tuning_Guide.pdf ), even though that's aimed at overclocking. ------------- 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 |
