Issue with my MSI X99 MOBO/ RAM

[Clint E]

Okay I am having a very annoying issue with my PC. Anytime I remove power from my machine (turn the psu completly off) I get 6F error when I turn machine back on. It is not until I physically remove all my RAM with the exception of one stick that is needed to start the PC will my PC turn on allowing me to get access to BIOS, I then turn the machine back off reinstall my RAM and good to go, any suggestions? This mobo was RMA for this resaon and MSI could not duplicate..... I have tried two different brands of RAM and the issue followed. I have also inspected the CPU and reseat the CPU twice... It is a frustrating issue and it is also hard for me to just pull out hardware to inspect, I have a full water loop. I have run a few memory tests and all passed, CPU stable. no obvious issues when I am playing games.

MSI X99 Gaming Carbon Pro
5820K 4.3 OC
32 Gb DDR4 2400
1080TI ASUS
960 PRO NVME
Windows 10

Bios up to date as well, any suggetions

since MSI could not duplicate the issue, answer the following:
1. why turn off the psu? just turn off pc without turning off psu switch.
2. have you tried replacing CMOS battery ( CR2032 ) ?
3. have you tried using 2 memory slots only instead of the 4 (i assume you have (4x8GB sticks) ?

1. I am still adding things to my build, RGB spesifically and need to put PC on my workbench so PC iis comptely turned off (when I turn PC off normally this issue is not present)
2. Yes
3. Yes I have tried actually 3 combinations. and no I use 8 4gb DDR4

Make sure there isn't a plastic film that's preventing the CMOS battery from maintaining power to the motherboard.

Battery not the issue...

Only thing I can reccomend really is to make sure the bios is fully updated, X99 was first to use the DDR4 so some manfactures had weird little issues with RAM.

How did you overclock? Did you use the auto overclock? If so, set the CPUback to stock for awhile and see if the problem goes away, if it goes away, try to manually overclock and see if the problem returns.

Yea I am thinking it is a issue with BIOS, I have done both as far as overclocking, My MOBO has the OC dial on it so it is currently set, I have found that if i switch everything to default before killing power somtimes (not always) it will start back up. But just last night I removed power again after resetting to default and the issue happened again, that was frustrating (added my new power cables last night). Struggle continues

You can check RAM timings with CPUZ or simular software, make sure the board is leaving the RAM alone, leaving all the latency settings at stock.

You can set the RAM devider, not sure how MSI lables it, but if you set the RAM devider, you can set it at a lower Mhz then stock, or a higher Mhz then stock but higher usally leads to problems.

Give your RAM more voltage, Just note 1.5v is about as far as I would ever run DDR4 RAM at. If its at 1.2v up it to 1.25v or 1.3v and give it a go.

Bios, you can go to MSI and download the updated bios, extract the contents of the ZIP onto a flashdrive, restart and go into bios and use M-Flash and direct it to the flashdrive and select the bios file, should be a ROM file. MSI does have a video on their website on how to do it.

If M-Flash can not see the contents of the flashdrive, boot back into windows and format the flashdrive to fat32 and extract the contents back on the flashdrive and go back into bios and use M-Flash and direct it back to the flashdrive and follow the diirections.

Updating the bios may even increase the max overclock you can get, never know.

I will try

Hi, I just have the same problem with my msi X99 mobo, each time I unplug the power and startup some time later I get the unending I9/55/b6 cycle of RAM failure. After years off playing with slots and BIOS resets I have found that gently shaking and pressuring the RAM bars in their slots right on startupon startup lets me startup again and configure the XMP profiles afterwards. Please spread this solution I have raged so much over this

That MOBO ultimately died on me with the Ram slot be the suspected culprit and MSI actually refunded me the full amount as they couldn’t fix it nor had a replacement. In the end it worked out well for me
