Suddenly board will only post with one stick of RAM

[JohnBonhamsGhost]

MSI Z97 Krait
DDR4 2400 G.Skill Ripjawz Z 2x 4GB

just will not post while both sticks are inserted now. worked fine for 6+ months running in dual-channel.

have tried everything i can think of:
each of the two sticks works in each of the DIMM slots separately
have tried lowering speeds to 1600
tried reloading XMP profile
have tried upping voltage in .01 increments from the stock 1.65 to 1.70
tried reapplying latest BIOS update
tried resetting BIOS/clearing CMOS
memtest and mdsched show no problems with either stick

is there anything else anyone would suggest here that can be attempted before going through motherboard support for RMA/replacement?

The DIMM that you were using the other module in might have died, or you might not be getting enough wattage directly to the DIMM lanes. (I doubt this though. Probably just a dead DIMM lane.)

Look at the ram slots and see if there is obstructions and/or bent pins.

That's why I suggested that maybe it was a MoBo issue or a DIMM issue.

Try putting one module in different lanes and see if that helps. If not, let me know.

each stick, means both sticks
each of the DIMM slots, means all 4 DIMM slots
tried each...separately, means both sticks have been run through all 4 DIMM slots. and both sticks worked in all 4 slots separately.

I figured he meant that he tried both STICKS, not all DIMMs.

Same here, did you buy the sticks seperately or in a pack

Yeah, not your fault or nine that we took it that way. He's also voting down our posts. Nice.

"DDR4 2400 G.Skill Ripjawz Z 2x 4GB"

only way they come is in a package

Do you have another set of dimms laying around

 

[Ironarmygeneral]

Based off of the information we have, I'd say it's a MoBo issue. Have you messed with the BIOS settings since it stopped working?

i will have to argue that it is written in plain english that each stick was tried separately in each DIMM slot. you also commented about wattage and BIOS settings when both are also stated as something tried.
if you don't want down-votes, read the post you are commenting on before zipping through asking questions clearly stated and recommending things clearly already tried.

Jesus. We're trying to help you here. Your information may have been in plain English but to me at least was NOT very detailed. I didn't understand half of what your were saying you did, so I'm just trying to go by what I thought it may be. Even if you have done some of these tests once, it is good to try each again just in case something else caused the issue.

I'm sorry that it comes off as rude. I don't mean it as any type of insult but you probably shouldn't be offering advice if you don't understand basic PC terminology like I've used.
I should expect it though. everybody wants to get the badges and points and many just read a title like this thinking about an easy fix without seeing what is actually going on.

I understand perfectly computer terminology. But I didn't understand what you said in the way that you used it. I build computers and fix them for a living (as well as sound systems and other electronics), so I DO know what I'm talking about.

 

[Ironarmygeneral]

I honestly could care less about the badges. I just want to help people. But if you don't want help, I can always leave.

I have my comptia A+ and am going to school in computers so I know the terminology

Lol, cool. I've got my prized possession: Three Titan X PC with a 5960x chip over-clocked to 4.5 GHz (4,550 MHz) and my other masterpiece, a 50,000+ watt surround sound with an RMS of around 35,000-40,000 watts. xD)

 

[Ironarmygeneral]

I have to go for now. You decide whether you want my help or not.

than you should be able to read and understand what has already been stated and agree everything you have offered as advice has already been done.
if you have something outside of this to offer I would like to hear. but taking a few seconds to read the original statement would have saved you the time of typing 4+ posts here. if you take that as some kind of insult, it isn't meant that way.

but getting emails every ten minutes about updates to my thread(s) with people posting those things clearly already outlined in the first post just gets annoying. that probably shouldn't effect my attitude towards those trying to help, but it has.

I didn't understand what you said in the first place, (comprehension wise), so I just decided to give any solutions that I thought it may be right off the bat, whether you had tried them or not. Even if you HAVE tried something already, it's good to try again under different circumstances and/or new scenario, even if the new scenario is just a changed clock, voltage, configuration of something not even the problem.

So I'm guessing by what we have now that it's just a bad motherboard. If you have any other MoBos laying around, test one of those.

OR, it could be a problem where the PSU is malfunctioning, or shorting, and not giving enough power to the motherboard. If that happened, the motherboard could have ALSO shorted in some units.

It could also be your CPU. Your CPU has a RAM controller on it.That might have broken or been messed with by accident.

Solutions:

Try using different motherboards, different PSUs, different RAM modules again as well as retry those modules in the different DIMM slots again.

The last thing that I would try before buying anything new or delaying the cause, I would rebuild the whole system and also start from a reset BIOS like you did when you reset the CMOS battery.

If none of this helps, I would suspect the HDD or SSD you are using. Sometimes they can cause issues, like shorts, malfunctions, etc.
