I currently have (2) 16gb Corsair Vengeance RGB 3200mhz sticks of ram and (2) 8gb G-skill 3200mhz sticks of ram on a Asus Tuf Mark 2 motherboard. I cant seem to get them in the correct order so that they all run at the correct speed and on dual channel. I tried to organize them exactly as it says in the manual and the computer will not even start when they are like that. Any assistance would be appreciated. Thank you.
[SOLVED] Need help with proper installation of memory and how to get a better benchmark score?

Clear the CMOS.
Its likely you won't be able to OC the ram much (or at all) with 4 sticks installed. So it's best to start back at having everything at stock speeds and then see how high you can go.
If you really don't need 48GB's of ram then just use the two 16Gb sticks. Again you still want to clear the cmos and then adjust settings once its working. Ryzen processors love rams speed, The faster ram runs, the faster everything runs. Intel is not so tied to ram speed.

It's Intel. Either a Z270 or X299.
For the Z, pull the power plug. 16Gb in A2/B2 and 8Gb in A1/B1. Then reset cmos by pin or battery.
For the X, pull the power plug. 16Gb I believe is A1/C1 and 8Gb in B1/D1 for quad channel or any 2 sets 1/1-2/2 for dual channel. Then reset cmos.
Different vendors can have different setups, so check in bios to make sure the 16's and 8's are configured correctly.

Can you go into your bios set your voltage to the higher voltage req (1.35v I am guessing) then set it to 20-20-20-60@ 1200mhz. Then putting in the ram sticks like the motherboard says and see if it will boot? If it does boot then you just need to tighten the timings then test. If it does not boot then something else is the problem.
I dont really understand the problem. If you have 1 16gb and 1 8gb in the same channel then 8gb will be in single channel.
For 6 core and above 1st set goes into A1 and C1 2nd set goes into B1 and D1. All white slots.
For 4 core 1st set C1 and D1 C2 and D2
So whats your CPU?

this is straight from the manual
Intel® Core™ X-Series Processors (6-core or above), you may install varying memory sizes in Channel A, Channel B, Channel C, and Channel D. The system maps the total size of the lower-sized channel for the quad-channel configuration. Any excess memory from the higher-sized channel is then mapped for single-channel operation.
Maybe it is in quad channel and your putting 8gb from each 16 gb stick in single channel. I am not sure

That's Flex mode, and not specific to X299. Putting any 2 DIMMsin the a different channel results in dual channel for the entire smallest DIMM, with a matching amount from the largest. Any leftover on the bigger DIMM is treated as secondary access single channel. In software, it's not listed as Flex, it's listed as Dual Channel.
Because here's the kicker, it's dual channel anyway. 16 in A+C, 8 in B+D = 32Gb in quad channel + 16Gb in Dual channel.
If you use the right slots. Use the wrong slots and it's all dual channel. Any combination leaves 2 channels with single channel dimms, = dual channel. Only way to get single channel on an X299 is by using an odd number of dimms.
Ram should work, if it's compatible. Might require several reboots to train the ram/memory controller if it is.
If the ram won't work together , boot into bios with whatever will. Then set the Dram voltage for 1.4v. Bump VCCIO 0.05v. No XMP/DOCP. Replace ram. Reboot 3x. If that doesn't work, bump VCCIO another 0.05v. If that doesn't work, bump VCCSA up 0.05v. If that doesn't work VCCSA up another 0.05v. Remove/replace the extra 2 sticks between each reboot.
If none of that works, consider the ram as incompatible. Which does happen when mixing ram.
i have a intel i9 7900X in a Asus Tuf X299 Mark 2 motherboard. Im trying to properly install (2) 8gb G-Skill 3200mhz sticks of ram and (2) 16gb Corsair Vengeance RGB 3200mhz sticks of ram. Ive tried many different configurations and most of the time the computer wont even start the only configuration that the computer will start and recognize all the ram is if i put all 4 sticks in the last 4 ram slots but it doesn't seem right and when in run a benchmark test on the ram i get a really bad score considering i have a good amount of ram and its pretty fast ram too. So the only thing i can think of is its in the wrong configuration in the motherboard. Also i have not been resetting the bios by pulling the cmos battery when in change the configuration. Could this be the reason? This is what the ram comes up as in CPU-Z.

Memory is only guaranteed to work at a specific speed if it’s sold in a kit. so you could buy identical sticks from the same manufacturer and they might not work together. you have to buy it in a kit for it to be guaranteed to work at those speeds
In your case you would want a kit of four sticks
There are other memory gurus here who can help you with the timings in the BIOS to see if you can get it working straight. If not it looks like you lost the silicon lottery

Worth a shot. The cmos is a volitile chip on the motherboard that contains files given to it by bios and Windows. It's powered by a battery to maintain those settings on a more permanent basis to cover any time the motherboard is without power. By resetting the cmos, you wipe out those files and force bios to re-aquire all the equipment and components and move the settings to a factory default condition which is contained in a non-volatile hardcoded memory.
You added ram, but bios got confused and had no idea what to do, because what's there and what the cmos says is there is 2 different things. Bios needs to 'discover' the ram and implement the ram jedec tables to allow the memory controller in the cpu to function correctly.

I'm saying you need to see if it will boot into windows with all 4 memory sticks installed correctly if you run it below the rated specs. Then you can tighten the timings or push more voltage to get the rated speed. but if it will not even boot into the bio's with the memory sticks in the correct ram slots you need to boot into the bio's with just 2 sticks of the same ram then put in manual memory settings to unclock it. Then place all 4 sticks in and see if it will boot into windows.
As far as the cmos battery affecting booting up. I don't know enough about x299 or your motherboard to answer that.

i guess its worth a try before i start to mess with manual timings. Ive been advised by others that if its not reset by pulling the battery then it will not accept the new ram and settings so i figure its worth a shot if not im just gonna get all new ram cuz i think its to much work just to get 16gb of ram to work. my corsair vengeance rgb ram works fine so thats 32 gb for now that should be good until i get new.
i only think it may work because currently i have all 4 sticks in my last 4 slots which is incorrect according to the manual but when i installed them i reset by pulling the battery. When i have been installing the ram according the manual i havent pulled the battery and it hasnt worked at all the only configuration that works is them randomly installed in the last 4 slots i think it may have to do with the battery being removed. worth a shot anyways.
I found a really good reason for me having issues. I've been a complete airhead and forgot I'm running a profile in my bios ai overclock tuner: XMP. / XMP: XMP DDR4-3200 16-18-18-38-1
Most likely the issue. I originally had just the two 8gb and added the two 16gb. So with new info any suggestions?
