Ryzen 1700 pc booting issue

[Ranjit]

Each time I turn on my ryzen 1700 pc, it powers on and shuts off twice before finally booting the third time. What could be the reason and how to fix this?

My config: ryzen 1700 oc to 3.6ghz gtx 1060 corsair 16gb 3000mhz ram running at 2400mhz. samsung 850 evo 512gb corsair rm750x, Corsair 570x case

This is usually due to the "AM4 Advance Boot Training" feature (as my ASRock board calls it). When you adjust memory frequency, timings, or voltage, your system will attempt to 'train' or learn the Auto dram sub-timings. It'll cycle power off/on a few times trying different settings until it finds one that will POST. You could go through your dram sub-timings and manually enter in the values the board selects instead of Auto. Once it's successfully booting, you can disable the boot training feature (if that's an option).

 

In my screenshot, I could copy over the 4,11,22,0,6,6 instead of Auto. Theoretically, if I understand the training feature correctly (and those timings are good), it shouldn't cycle off/on anymore.

While this is a feature that's "working as intended", it is annoying. You could visit your board maker's support section and download the most recent bios release. They tend to improve system stability and memory compatibility. This may help it 'train' better timings and not cycle off/on.

Yes, my dram timings are currently set to auto.

I have an asus crosshair vi hero (BIOS version 1601)  and CORSAIR VENGEANCE LPX 16GB DDR4 3000MHZ MEMORY CMK16GX4M1B3000C15. currently it runs at 2400mhz. Pls provide the timings for it to run faster and not cycle on/off in this interface with screenshots if possible and after doing so how to turn off " boot training".

From the support site, I see bios versions 1501, 1602, 1701. Either way, 1701 was released four days ago. I'm not saying it will help, but the Ryzen platform is still too new, in my opinion, to ignore bios updates. They fix important matters. https://www.asus.com/us/Motherboards/ROG-CROSSHAIR-VI-HERO/HelpDesk_BIOS/

From the part number, this is one 16GB DIMM. I've not encountered anyone using only one stick of 16GB, but I'm pretty sure Ryzen is too new to make this work correctly. Right now, Ryzen seems to prefer 2x4GB or 2x8GB. I'm no expert on dram with Ryzen, but it may simply not like having only one DIMM of 16GB. You may be limited to 2400, or you might be able to tweak it higher with better timings.

 

Just to make sure, are you inserting that DIMM into the recommended slot on the board? DIMM_A2

There is a program called Thaiphoon Burner which can Read the SPD data and display some of the timings. There are ways to determine all the other sub-timings, but it's easiest to let the board choose them, then simply copy them over (as in my screenshot). If you're interested in the "difficult" method of acquiring a list of sub-timings that may work, I'll provide a link to a Google Drive spreadsheet I bookmarked a while back. Make a copy of it and save it to your own Google Drive. Ryzen system calculator v 0.9.2 by 1usmus There's plenty of information to be gained in the links at the bottom, including an English version.

Thanks a lot for your detailed explanation. Appreciate it. I'm now thinking of getting another ram, probably gskill flare x which is optimized for ryzen.

It's no problem. While most will probably point to your board's support page and the memory QVL, the best choices will be kits which contain Samsung B-Die. It's more expensive, but has the best chance to work well with Ryzen, and overclocks nicely. Perhaps cross-reference that QVL list with B-Die kits.

 

https://pcpartpicker.com/products/memory/#s=403200&Z=16384002&L=140 contains some of the more popular Samsung B-Die kits. It's not a complete list, but it'll be a good starting point.
