Adding more RAM to Infinite RS 11TG-234US

There are four memory slots on the motherboard. Slots 1 & 3 are factory populated each with XPG 8GB DDR4 3600 modules. Slots 2 & 4 are empty. I bought another 16gb (2 8gb sticks) of Corsair Vengence LPX DDR4 3600 to boost the total RAM to 32GB. However, when I install the new RAM in slots 2 & 4 the computer will not start. No lights. No fans. No nothing. When I remove the RAM modules from slots 2 & 4, pc starts up as normal.
Am I missing a step for adding additional memory to this box?

Install the newest BIOS and try again: https://us.msi.com/Desktop/Infinite-RS-11th/support?sku_id=83467
Use M-Flash in the BIOS to update from USB.

In general, mixing different kits of RAM will confuse the CPU's memory controller and can lead to all kinds of problems. If you want 32 GB, it's best to replace your 2x 8GB with 2x 16 GB.
Read my thread RAM explained: Why two modules are better than four / single- vs. dual-rank / stability testing, which should hopefully clear up a bunch of things, including if you really need 32 GB.

It's important to realize that there's only one set of parameters that can be active for the whole memory system, and it's determined during memory training. So if you use two different kits of RAM, the memory controller needs to find a middle ground between those kits (which would really need two different sets of parameters). This is a conundrum which may not always work very well.

Also, if the original kit was in the first and third slot (A1 and B1) to begin with, that was already wrong. With just two modules, they always go into the second and fourth slot from the left, A2 and B2.

Thanks for your response. I'm waiting for the delivery of usb drives, so haven't flashed the bios yet. I did download the bios update (E7D09IZ1.AD2) I have to say, just the thought of the process makes me uneasy. I'm under the impression that if something goes wrong during the process I may end up with a bricked pc. Is that true? Also, is there any benefit to backing up the current bios to "reflash" it back to its original state if something goes wrong? Is that even possible?

Yes, this box was received from MSI with 2 8gb memory kits installed in A1 and B1. Because I work with large video files I want to increase ram so I can use a ram drive to help speed up the process of working with these files.

There's not much to worry, i've done BIOS updates maybe a few hundred times in my life, and only once did i ever have a problem, but even that could be fixed in the end. Of course here on the forum we see a few more cases (especially since they come here mainly in case of a problems), but in the grand scheme of things, a BIOS update is pretty safe. Plus, with RAM compatibility problems, it's literally the first thing you should try, because a lot of that depends on the BIOS.

Those MSI pre-built systems can suffer from some problems, see here, https://forum-en.msi.com/index.php?...p-constantly-overheating.375314/#post-2128332
The RAM modules being in the wrong slots is a new one. Slots A1 and B1 are not correct on a board with daisy-chain RAM slot layout, because if the slots are populated like that, then the empty slots A2 and B2 to the right of the two modules will act like loose wires at the end of the RAM contacts, causing unwanted signal reflections and such. Like i explain in my RAM thread.

Like i also explain there, it's best to replace your 2x 8GB with 2x 16 GB (of course in A2 and B2 then). This is an option if the newer BIOS doesn't help and we can't get it to work any other way.

Another thing about your video files: You should work on a large project and see how much RAM is utilized in the performance view of task manager under RAM. If you see that even on the largest projects, you're not getting anywhere close to 16 GB RAM utilization, then upgrading to 32 GB would not achieve anything. Your bottleneck is somewhere else then.

Thanks for quelling my uncertainty about flashing the bios. On the back panel of this box is a "Flash BIOS Button" and a USB port labeled "Flash BIOS" which I'm supposing is where to plug in the USB drive with the bios update, and pressing the labeled button is how to start the flashing process??

The other forum post you reference about overheating is also mine. This pc was overheating and shutting off so I upgraded the cooler to a 280r and that solved the overheating problem.

I didn't try this but am wondering if I move the factory-installed ram to slots A2 B2 (where they should be) and put the new ram in A1 & B1 might that solve the problem...?

I read your article about ram and how 2 16gb modules are better performers than 4 8gb modules. Very helpful info.

The Flash BIOS Button is only in case you can't flash any other way, or you have indeed bricked the BIOS flashing the normal way. It's a tool to get the system working when a new CPU requires a new BIOS version and you don't have an old CPU to update, or a safety net in case of trouble.

To update normally, extract the BIOS file onto a USB stick, enter the BIOS, enter M-Flash and select the BIOS file there. This is what you should do.

You can try switching the RAM kits around, sure. But first the new BIOS.

To close this thread: I seriously considered updating the bios of this computer. When I followed the link to MSI's instructions on how to proceed, two warnings caught my eye. First, the page says if your computer is working without trouble, don't update the bios. The second warning spoke to me directly, "If you don't know what you're doing, don't attempt the update."

Rather than take the chance of doing something wrong and regretting it, I decided instead to take the advice you offer in your post about RAM, to purchase 2 16GB simms for a total of 32GB. I removed the original 8GB simms and installed the 16s and everything works as planned. I now have plenty of memory to do video editing/processing.

Thanks for your RAM article and for pointing me in the right direction.

Good. Don't worry about these warnings though, MSI put them there mostly for liability and "support avoidance" reasons. Ideally, they want to sell you a product and then never have to deal with it (or you) again. The more you tinker with it, the higher the chance you're gonna contact the support about it. Unfortunately, each BIOS has a myriad of bugs (typical "bananaware" that ripens after it's sold), which slowly have to get fixed via BIOS updates. Buyers who realize that certain things happen because of an immature BIOS will update their BIOS, and they generally are happy when things run smoother afterwards. People that "don't know what they're doing" might update the BIOS, the custom settings get reset to defaults, and they're lost, so they are more likely to contact support.

MSI also like to obfuscate things as much as possible by (in your case) delivering NO changelog whatsoever, or for the retail boards, posting just one- to three-line-changelogs, although each BIOS update can contain literally dozens of little fixes and improvements. They're not alone in doing this, but it certainly doesn't inspire confidence when you don't know what you're updating the BIOS for.
I have explained it all a bit more here.

Anyway, you made the right choice by getting 2x16 GB DIMMs.
You still calling them "SIMMs" could mean you are in the PC game for 20+ years? In that case, you should slightly know what you're doing by now 😉

Your point about the lack of a changelog of changes/benefits ranked top on my list of uncertainties. Everything seems to be working properly so why take the chance?

This box is used in a small business and the thoughts of bricking it were enough to convince me to take your advice and buy the 2x16Gb *DIMMs*. Your intuition about my experience in the PC realm was a good one. Been in a long, long time. I'm pretty good about most computer things. Oddly, though, bios programming/updating isn't something I ever found myself needing to do.

Thanks for your good advice and willingness to help MSI customers.
