Four Sticks 6400MHz CL30

[day187]

I managed to get my four sticks running at 6400 CL30 only 64GB stable,

I had to put all the settings in manually and it took about 5 minutes to train the memory from boot, but now the PC boots up straight away, I just wanted to share my settings as they might be useful for somebody.

That is nice 🙂 . Decent FCLK also. Later UEFI as in use there is supposed to improved gains on RAM. Best result I think I've seen to date on 4 DIMMs 😎.

Maybe you can help.  I have a Asus x870e-e with 9800x3d.  Running the 1003 bios and everything up-to-date per Asus website.  My memory is Corsair Dominator Titanium 4x16GB DDR5 DRAM 6000MT/s CL36.  QVL listed (CMP64GX5M4B6000C36).  My system boots when set to Auto (freq is 4800).  I set AI Tweaker to DOCP.  Went to "Save Changes & Reset" and noted the changed settings.  Canceled the changes and went back to AI Tweaker.  Set it to Manual and manually changed bios settings to match what was to be changed with DOCP except reduced the frequent to 5800 instead of 6000 (per comments by others that 5800 works better).  On reboot, got a Q-code 15 with a red LED.  Waited about 5-7 minutes and Q-code changed to 99 with no LED lights.  However screen was black.  Ultimately did 2 or 3 resets (waiting minutes between resets) and eventually the option for selecting bios came up and quickly started the process of booting to Windows.  Ultimately got a BSOD.  Tried many times to reboot using the reset button or turning off power.  The Q-codes came up fast and furious with yellow, white, and green flashing on and off.  Many times it got to a Q-code of 99 with no light but my screen was black.  Keyboard, mouse, fans, and motherboard looking like all was well.  At no time was I given the chance to go into the bios.  Ultimately had to Clear the Bios.  After a time an insufferable amount of time and maybe at least one reboot, I got into the bios.  Made minor changes and got into Windows.  Memory frequency is set to 4800.

Is there anything I could do differently to make this memory work at higher frequencies?  Did I follow a good procedure? Is this a wait until there is a new bios available (hesitant to try the beta 1103)?

Thanks

Hi I will try and help mate

Make sure your memory kits are installed side by side first kit A1 A2 second kits B1 B2

Do not change anything else in the bios after you cleared the CMOS only change the settings below till you have it up and running

1. Clear CMOS
2 Set the memory speed manually to 6000MHz (do not use EXPO/XMP)
3. Keep the timings on Auto and let the motherboard choose the timings (timings can be changed once you get the 6000MHz up and running)
4. You can either set the FCLK to 2000MHz or leave it on Auto (I recommend Auto to start with)
5. Enable high DRAM voltage and set the MEM VDD to 1.4v/13.5v and set the MEM VDDQ to the same 1.4v/13.5v (you could try 1.4\1.45v if needed)
6. Then F10 save and leave it to train the memory for up to 5/7 minutes (on F15 led code) and it should boot

If it boots then you can go back into the bios and make some changes to memory timings - UCLK and FCLK

Good Luck and let me know how you get on

Hi,

Thanks so much for helping me out.  I’ve always had trouble with memory clocking so getting expert help is appreciated immensely.  I want to provide to you more information in case it might change your guidance.  In your post I saw you used Zen Timings (used before on an Asus Dark Hero MB) but I couldn’t get it to open this time.  Whatever...so I used a trial version of AIDA64.  Here are pics from the AIDA Report of the memory timings.

Does this info change your guidance or should I continue on the path you suggested?

Thanks so much

Did you manage to get it to boot at 6000Mhz?

If you did not get it to boot I would start 1.35v 5000Mhz and go up but 200MHz at a time till it won't boot and then up the voltage of the VDD and VDDQ in stages of 0.25v do 1.375v 1.40v 1.4v 1.425v 1.45v

if you get it running then set your timings to 36-36-36-76 if these are the timings for your memory,

I've got mine to boot at CL 28-37-37-96 but I am still testing 😃

[Mr_Savy]

Frustrating to say the least.   I'll try to give blow by blow.

1. Following your initial guidance of speed @ 6000, FCLK on Auto, High Dram Enabled, Voltages @ 1.35.  Got Q training code 15 for 4min then 62 white led at waited 10 min total.  Had to hold down Start button to power down. On boot got 0d green led and didn't go further. Powered down.

2. Clr CMOS, got stuck on b4 (USB hot plug?). Then forced reboot and then got into BIOS

3. Set  speed @ 6000, FCLK on to 2000, High Dram Enabled, Voltages @ 1.35. Q-code on 15 (training) for 10 min. Powered down. On booting got 0d.

4. Clr CMOS, on boot got Q-code 99 with green light. No further, so rebooted. Got a bios crash message but got into bios.  Decided to go down your alternative path. 

5 Set speed to 5000 and DRAM voltages to 1.35, high dram voltage enabled. Successfully booted to Windows. Rebooted & got into bios.

6 Set to 5200 but I think it was successful but don't remember. Got into Windows

7. In bios set to 5400, won't boot. Set voltages to 1.375 and boot into Windows.

8. In bios set to 5600 and got into Windows.  Rebooted and system crashed.

9. In bios set to 5800 with voltages set @ 1.4V.  Looked like it was going to boot but got a Q-code 68 white light.

10. Went back to 5600 with the 1.4V and booted into Windows. On restart "booted" tto black screen.  Then eventually got into bios and set speed each to 5400 then 5200 with no boot.  At 5400 set voltage to 1.375.  So in the end unsuccessful.  So I gave up. Set everything back to Auto and successfully booted 😞

I guess I'm going to wait for the next bios non-beta update and try again.  A question for you though.  In the jpegs posted, I see for Profile 1 & 2, the VPP is set to 1.8V and Voltage (Memory Controller) set to 1.2V.  Should I have also been using these settings?

[day187]

Some  people can't get their memory to run over 5400Mhz with four dimms

You can try setting the VPP  to 1.8V and Voltage (Memory Controller) to 1.2V. , mine are set to Auto and that's the values the motherboard gives me..

Have you got the X870e Hero motherboard?

[Mr_Savy]

Maybe successful. Your comment about others with 4 sticks not being able to get by 5400mhz was helpful.

Set frequency to 5400, VDD & VDDQ to 1.35. Set VPP to 1800mv. I wasn't sure where the "Voltage (Memory Controller) was in the bios.  I think it's under Advanced-AMC OC.  I saw 2 settings.  one is called VDD Misc Voltage (currently was at 1100mv) and the 2nd was DIMM VDD Adjust.  It was also at 1100mv.  I wasn't sure if either is the same as Voltage (Memory Controller) so I didn't change anything.  Can you confirm where the setting is located in the bios?

After training the system booted successfully into Windows.  Restarted and it again got into Windows.

Got back into the bios and made the timings 36-36-36-76.  Looked like it was going to boot but got a black screen & keyboard was unpowered.  Forced a reboot and successfully got into Windows.  I probably should go back and set the Voltage (Memory Controller) to 1.2V or 1200mv.   I'll wait until you confirm where it's located.  

At some point, I'll do a stress test but for now happy to have increase frequency and into Windows.  Thanks for your help!

My motherboard is the Asus x870e-e
