blurb2m Posted January 8, 2019 Share Posted January 8, 2019 BLUF: How to understand dmidecode to see if RAM is running at full clock speeds. (output of dmidecode --type 17 attached) Server has been running smoothly with 2x16GB sticks of GSkill Ripjaws (F4-3200C15D-32GVR) in dual channel mode with XMP Profile 1. ASRock X399 Taichi | TR4 2950X Windows VM was eating up a ton of RAM for Blue Iris NVR, so I decided to buy 2 more sticks. Popped them in the slots according to the x399 Taichi motherboard chart (D2,C2,B2,A2). BIOS is showing Quad Channel now and it was freezing like crazy on POST, so I went in and switched the Memory profile to "Auto" and it seems stable and showed DDR4-3200 for the speed. Does the information attached (txt) support what BIOS is reporting? Is there a better setting I should be using? Any help is greatly appreciated! tr4-ram-dmidecode.txt Quote Link to comment
Vr2Io Posted January 8, 2019 Share Posted January 8, 2019 (edited) In your 2nd BIOS pic. bottom, it show (1066MHz) and match DMI txt show 1067 MT/s. ( That is 2133 ) Some report also say DMI info. not always correct. Regard your stick haven't JEDEC 2400, 2666 middle profile. Edited January 8, 2019 by Benson Quote Link to comment

Should I move 2nd set to different slots? Quote Link to comment
Vr2Io Posted January 10, 2019 Share Posted January 10, 2019 (edited) Sorry misunderstand you have 8 stick now, that's weird 4 stick can't run in stock freq. According manual, 4 stick in A2/B2/C2/D2 was correct. Could you confirm they run in 1.35v (XMP) or try manual set memory voltage to 1.35v. Pls also verify timing parameter does correct recongize and match with XMP profile. Edited January 10, 2019 by Benson Quote Link to comment
blurb2m Posted January 10, 2019 Author Share Posted January 10, 2019 (edited) No I'm running 4 sticks. Let me take some new pictures from BIOS. That second picture might have been prior to switching profiles now that I think about it. Edited January 10, 2019 by blurb2m Added pictures Quote Link to comment
Vr2Io Posted January 10, 2019 Share Posted January 10, 2019 (edited) Suggest set memory to 1.35v first ( avoid freezing like crazy on POST ), then tweak "Load XMP setting" from AUTO to other i.e.3200, and change/check other memory relate setting if need. Your memory now in 1.2v Edited January 10, 2019 by Benson Quote Link to comment
blurb2m Posted January 10, 2019 Author Share Posted January 10, 2019 Changed Load XMP setting to XMP 2.0 Profile 1 (3200) and voltage to 1.35. Voltage auto-set when I changed to XMP 2.0 Profile 1. Unraid froze about halfway through bootup. Stopped at: sev command 0x4 timed out, disabling PSP SEV: failed to get status. Error: 0x0 So, I think when I changed to AUTO it had not updated yet the other day to show 2133 and 1.20v. It has been stable for a day at those lower clock settings. Not sure of what else to change to get it to run 4 sticks at 3200. What my limited knowledge has gathered so far: 2 sticks @ 3200 and 1.35V = stable 4 sticks @ 3200 and 1.35V = unstable 4 sticks @ 2133 and 1.20V = stable. Quote Link to comment
Vr2Io Posted January 10, 2019 Share Posted January 10, 2019 (edited) Too bad, I haven't TR, but I have prepare memory for TR build, so you may give me some idea. Hope you cound found solution. The memory was Ballistix Tactical 32GB Kit (8GB x 4) DDR4 3000 MT/s (PC4-24000) DIMM 288-Pin Memory - BLT4K8G4D30AETA , it is quite cheap ~usd225 and not available now. Speed not that aggressive.

blurb2m Posted January 10, 2019 Author Share Posted January 10, 2019 (edited) I might try messing with the timings tomorrow to see if I can get higher speeds. Its back at 4 sticks @ 2133 for the time being. I was going by this for B-Die for TR builds. https://benzhaomin.github.io/bdiefinder/ This is the thread that lead me there. https://www.reddit.com/r/Amd/comments/8clf15/bdie_finder/dxgd1d9/ Edited January 10, 2019 by blurb2m Added link to reddit thread Quote Link to comment
blurb2m Posted January 11, 2019 Author Share Posted January 11, 2019 I have been slowly increasing the clock speed and got up to 3066 stable on the 4 sticks. If I try going up to 3200, it freezes up on me after about 10 seconds into unRAID boot. I'll stick with 3066 for the time being until I can learn more about clocking these monsters.

Vr2Io Posted January 11, 2019 Share Posted January 11, 2019 (edited) Much better run in 2133. Higher chance of my sticks could run in stock 3000 CL15. Edited January 11, 2019 by Benson Quote Link to comment
blurb2m Posted January 11, 2019 Author Share Posted January 11, 2019 I'm sorry, but I don't follow? I'm stable at 1.35V and 3066 MHz. I think if I wanted to try and achieve 3200, I would need to learn more about overclocking RAM. Quote Link to comment
JonathanM Posted January 11, 2019 Share Posted January 11, 2019 I hope you have good backups elsewhere of data that you keep on your server. Overclocking is risky, as you've found. What seems stable because the server doesn't outright crash doesn't mean everything is working accurately. Overclocked server is a combination asking for trouble. Quote Link to comment

rallos_hoo Posted February 24, 2020 Share Posted February 24, 2020 sorry, RAM SPEED will improve unraid performance? Quote Link to comment
