X370 Gaming K4 - new BIOS with AGESA 1.0.0.6&a

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Very bad experience here with HX426C15SBK2/32 DS. On 2.40, even though not reaching 2666 MHz CL15, it was stable on 2400 MHz CL14 via XMP profile. Now on 2.50 can't reach even this, defaulting to 2133 MHz. Once successfully booted at 2400 and slightly higher voltage but couldn't reproduce. Rolling back to 2.40 :( It was supposed to have better compatibility, not worse...

	This news makes me a sad panda.. I'm kind of loathe to attempt the BIOS at this point..my eVGA memory (g.skill made, I think!) runs at 2933MHz, and I don't want to take a step back.

	Right, back to BIOS 2.40 and 2400 Mhz CL14 through XMP. Probably going to skip this version and hope they'll get it right next time.

Note just setting it to 2933 did not work i had to post at each setting below going up 1 step at a time starting at 2133. Edited by chainsaw - 11 Jun 2017 at 4:33am

	tried it anyway....my RAM still won't go above 2933MHz, which is what it says on the support page anyway.. Oh well...wait for the next one, I guess.. ;) Since it makes no difference otherwise..I'm just gonna stay at 2.5

	No luck here either. on 2.40 i could only get 2400mhz working. And with 2.50 it would get a 03 code when trying to load 2400 and f3 with anything higher. 1700x 3.9 ghz Corsair vengance led 3000mhz cl15 ram Edited by Ottesen87 - 09 Jun 2017 at 4:48am
	1+1=4 in my world and dont try to say otherwise

	are you guys trying the old tricks with this new bios ? eg setting command rate to 2t ? manually entering speeds and timings etc

	New update to 2.50 from 2.40 did me no good. I'm running Corsair 3600 RAM with Samsung chips. 2933 was all I could get before on version 2.40, and that is still the case. Edited by mgilbert - 09 Jun 2017 at 6:04am

	All of you guys having RAM stability issues should manually set the SOC voltage to Fixed mode @ 1.1V with LLC level 2. Then leave all other memory settings to whatever your XMP profiles defaults are. It's also worth noting that you NEED to reset your BIOS to defaults and power cycle the board after failing any RAM OC at POST, including XMP profiles, due to a BIOS bug. (Not even kidding) You could be trying to boot with an actual stable RAM OC but it wont POST because you failed the last POST. AMD suggests settings the SOC to 1.1V for memory stability. By default my board (x370 gaming pro) has a 0.95ish dynamic SOC voltage by default. Forcing the fixed 1.1V solved all of my memory stability issues. It's worth a shot. For reference I'm running @ 3334MHz tested stable.

	I was aware of having to power cycle the board. I tried setting the SoC as recommended, but it didn't help me. 2933 MHz isn't bad, but I'd love to get to 3600. Maybe the next AGESA...
