Your Patriot Viper memory, model number PVE48G213C4GY, which we can check in the link below, is to quote, "Built for the latest Intel platforms...": https://patriotmemory.com/product/viper-elite-series-ddr4-8gb-2133mhz-gray-2/ Your memory works as you know, but the latest information regarding using DDR4 memory designed for Intel systems is, the XMP profiles will not work for the Ryzen memory controller. That is really not surprising, as they are different systems, and the XMP data is configured for Intel systems. You said you set the memory timings and speed manually, which is what you must do when the XMP data is not applicable to the system you are using with your memory. You guessed the three restarts (POST was run three times, for memory training, or trying different timings) was to find an XMP profile. Did you check what the memory timings were set to now that the memory is working? Is it what you set it to manually? Of course at a speed of 1866 or 2133, the usual stock/default speed of DDR4 memory, the standard JEDEC SPD data would be used, not an XMP profile. Or was an XMP profile available for 2133? That is not clear on the Patriot page about this memory. The standard SPD data could work at 2133. Other models of this memory at speeds up to 3200 would have an XMP profile, but again the XMP profiles of memory designed for Intel systems are not compatible with Ryzen systems. Run CPU-Z and click the Memory tab to see the current timings being used. Click the SPD tab to check the JEDEC SPD data, and the XMP profile data. The problem ASRock solved was working around, at least for this model of memory, the timing data designed for Intel systems. |
I feel like I was just put on trial by you, not sure why, but I will try to answer.
I ordered the CPU's, motherboards and RAM before there was a QVL list on the ASRock website. I took a shot in the dark for my preorders. I kept the RAM because I believed ASRock would release a BIOS that would eventually work, and I did not want to pay a restocking fee.
Yes, I set the memory timings and speed manually, it is an old habit. I don't really know why it powered on to a black screen three times before it finally posted. But when I checked the memory settings after the 3rd boot, my timings and speed setting were unchanged, but there was an available XMP profile for the Patriot RAM. I know this because the G.Skill RAM timings and speed are different than the Patriot, and the XMP profile was showing the Patriot settings; 14-14-14-32 @2133
I explained what I did, step by step, in case someone wanted to duplicate it. I was not trying to be authoritative, just thorough. I have never worked with XMP profiles before, I assumed it was the way memory was identified by the BIOS now days. I can see I was wrong.

CPU-Z screens you asked for http://imgur.com/dVxsxdZ
You seem intent on pointing out my poor choice of RAM, but as I said, none of this information was available on February 22nd when I ordered it.
