Hello! I have a computer using the X99E-itx/AC motherboard with i7-5820K, Windows 10, GTX 970. It has been running for about 10 years and just recently had a crash it has so far not recovered from. I wasn't using the computer when it happened so didn't see any problems until computer was on, fans running but no video display. When I try to reboot, lights come on, fans run, I get 3 beeps from the motherboard, but no video output. I read online that 3 beeps for ASRock indicates a memory issue. I tried removing the 2 RAM sticks and replacing them with new (Crucial Pro CP2K16G4DFRA32A, 2x16GB) but no change in behavior. I tried pulling my GPU and putting in another older GPU but still no luck, still giving the 3 beeps. I'm considering trying a different RAM module(s) since I know this motherboard had some RAM compatibility limitations. Is that a likely issue or might the 3 beeps not actually indicate a problem with the RAM itself? I looked at the memory compatibility list here: https://www.asrock.com/mb/intel/x99e-itxac/#Memory" rel="nofollow - https://www.asrock.com/mb/intel/x99e-itxac/#Memory I don't see any of these exact model numbers available locally. Does it need to be an exact match or should the off-the-shelf RAM at Best Buy work? The RAM available locally (Best Buy) is: Corsair Vengeance LPX CMK32GX4M2E3200C16 Corsair Vengeance RGB Pro CMH32GX4M2D3600C18W Corsair Vengeance RGB Pro CMW32GX4M2D3600C18 Crucial Pro CP2K16G4DFRA32A Corsair Vengeance LPX CMK32GX4M2D3600C18 Other than trying different RAM, I'm kind of stumped and thinking something on the motherboard may have failed. What else should I try or look for? I don't have a lot of data at stake, have system backed up but I'd like to get the computer going again if it's possible. ------------- ASRock X99E-ITX/ac | Intel i7-5820K | ASUS GTX 970 mini | Samsung 850 EVO 250GB | Crucial Ballistix (2x8GB) | Corsair CX600M | CoolerMaster Seidon 120V | CoolerMaster Elite 110 | Windows 10 64-bit |

I emailed ASRock tech support and got the following reply: "Thank you for contacting ASRock USA support. 3 beeps indicate no memory installed or detected. It can be CPU, memory and/or mainboard. Please test with 1 x memory, switching another memory if it?™s same issue. Test with another known good CPU or test this CPU on another known good mainboard to verify if problem still persist." I don't have another X99 CPU or motherboard available to test with but I did order a stick of RAM from the published QVU/compatibility list to test with (fingers crossed). ------------- ASRock X99E-ITX/ac | Intel i7-5820K | ASUS GTX 970 mini | Samsung 850 EVO 250GB | Crucial Ballistix (2x8GB) | Corsair CX600M | CoolerMaster Seidon 120V | CoolerMaster Elite 110 | Windows 10 64-bit |

Testing with another compatible RAM stick (Kingston ValueRAM KVR21N15S8/4) has been unsuccessful. Still getting the 3 beeps and no video output. Occasionally it has turned on without beeping but with no video, I can't really tell if the computer is doing anything beyond running the fans and lights. ------------- ASRock X99E-ITX/ac | Intel i7-5820K | ASUS GTX 970 mini | Samsung 850 EVO 250GB | Crucial Ballistix (2x8GB) | Corsair CX600M | CoolerMaster Seidon 120V | CoolerMaster Elite 110 | Windows 10 64-bit |

Not ready to throw in the towel quite yet, I checked on Ebay and found that compatible LGA 2011-3 CPUs can be had for around $6, including shipping. I ordered a used Xeon E5-2603 v3. To my surprise and relief, my computer started up with the replacement CPU and with the single stick of Kingston RAM. It booted into Windows without apparent issue. I haven't tested going back to my Ballistix RAM yet but that's probably the next step. ------------- ASRock X99E-ITX/ac | Intel i7-5820K | ASUS GTX 970 mini | Samsung 850 EVO 250GB | Crucial Ballistix (2x8GB) | Corsair CX600M | CoolerMaster Seidon 120V | CoolerMaster Elite 110 | Windows 10 64-bit |

Glad to hear it. LGA 2011 CPUs, particularly Xeon variants, are a great deal on the used market for sure and the LGA 2011 platform still has a lot to offer. -------------

I put the Ballistix RAM back in and it worked happily as ever. It seems the CPU was to blame. ------------- ASRock X99E-ITX/ac | Intel i7-5820K | ASUS GTX 970 mini | Samsung 850 EVO 250GB | Crucial Ballistix (2x8GB) | Corsair CX600M | CoolerMaster Seidon 120V | CoolerMaster Elite 110 | Windows 10 64-bit |
