4-DIMM (2DPC) 2 rank at speeds of 4400-4800MT/s is the upper limit on what is achievable on Intel's current platform. Anything beyond that becomes unstable without significant manual changes in the UEFI. Another thing to note, if mixing different RAM kits, it's best to isolate them to separate memory channels to account for micro-differences between batch manufacturing. Currently if someone wants to run 4-DIMM for the aesthetics, the AMD X870E can handle 2DPC 1R at 6000MT/s. I have recent videos showcasing this.
That is a known issue with DDR4 and DDR5. The more RAM (dimms) you put the slower it will go. This might change on the upcoming AMD MOBOs and upcoming CPUs (I know you're on an intel platform). It depends on the CPUs integrated memory controller (lottery) and MOBO topology. As you found, the safest bet is 2 dimms for a total of 96GB.
When using 4 sticks or two pairs, each pair needs to be installed in the same channel. In other words, the first pair out of the box goes to A1 and A2 slots and the other pair goes to B1 and B2.
Is that something you actually tried? I only ask since I tried this test at least half a dozen times, and I did not keep track of which were paired after the 1st try, with the same results for every attempt. I did see a video from anther creator, and your suggestion is what she suggested when using two kits with mismatched timing, however, she was also manually tweaking the frequency on the mother, which was not my intent to lead people through in this video.
@@PE4Doers Gskill is specifically finicky to get right. Shuffling the sticks placement in the 4 slots should get you to a scenario where the board successfully trains the RAM. Ideally with pre-paired kits you should follow the channel matching as the commenter said, but if that doesn't work, I'd shuffle the sticks around.
@@PE4Doers I used 4 sticks in my graphic design workstation and did some testing for my ideal setup (labeled each stick, tested mem performance in Windows). You're not chasing speed as a content creator, you want stability and quantity. Therefore, a 128GB bank is worth the bother IMO. Good luck.
Personally when building Asus AM5 platforms I noticed the memory training took longer every boot when enabling EXPO (XMP for AMD). Played with the memory timings manually and same issue. Stability was a more pressing issue and decided to leave timings on default without EXPO. Something with the Asus memory training routine at least on AM5.
I have two different MoBos using effectively the same ram (admit the XMP speeds are different) The GigaByte board with B650 chipset needed to have the ram voltage upped a little (was running 1.01 and I set to 1.1) and the voltage be controlled through all ram sticks individually. This allows my 4 sticks to Boot quick with XMP enable and full speed of the ram. The MSI board with the x670e is a bit different where I have had the issue for a couple years till MSI released a BIOS update 3 months back. I would still have really long training times, but the system would boot with RAM at full XMP speed (again, 4 sticks). Recently, I started messing around with Overclocking and come across the possibility that this board was also using too low of voltage for the RAM (right at the edge). I don't have the option for the voltage to be on individual sticks like the B650 but I could up the voltage to where the ram should be running. This Voltage adjustment (setting to 1.25v per XMP specs of my ram), solved the extremely long training time (cut by half) and I have stable full XMP speed on my 4 Sticks on this system. If curious, I use four sticks for the stupidest reason. I use RGB ram, and I like to have all 4 slots filled with the RGB. Otherwise, it feels like the system is missing something. I also recently learned that the maker of my ram does make Dummy RGB sticks. Oops..
Interesting. Thanks for the feedback. As I mentioned in my introduction, my intent was NOT to have the viewers of the video try and play with either the Voltages or Timing of the memory. I decided that very much based on the problems Intel is having with the Gen 13 and Gen 14th (Raptor Lake) CPUs. Though I know how those parameters work (being a Professional Engineer, specializing in computer engineering). I really do not feel comfortable making recommendations on changes to those parameters for the general computer-building population. It is possible that damage could result, and I do not want to be responsible for having encouraged such changes.
@@PE4Doers it's not just Intel. both systems I was talking about are AMD with Nvidia GPUs. I understand your thoughts on the tweaking the system as messing with voltages (I don't mess with the timings, only enable XMP) can damage the system. I only now found out that my MSI x670-e board was not setting the correct voltages as required for the RAM in XMP mode, same as the other AMD system with the b650 chipset. Looks to be a vendor configuration failure. Didn't really take the time to troubleshoot till I built the second system a couple weeks ago. I'm also Professional engineer, specializing in IT Infrastructure, and a Professional electronics technician.
@@Chewy6909 I'm not sure what CPU you are using to wanting 6000 but there is a good chance you will need to stick with 5600 if you get black screen at 6000. Besides upping the voltage (I do not recommend unless you know exactly what you are doing and the specs of all the hardware, otherwise you will break the system), there isn't much there these days. Maybe timings, but that is also a dangerous position. also to note. I build a third system with an x670-e ASUS board and was unable to get 6 sticks working this that regardless of configuration. In the end, I've updates all 3 systems with 2x 32GB sticks running at 6000 which has provided much better performance than running 4 sticks.
If your motherboard supports that, it would be a total of 192GB. However, the DIMMs would likely be limited in terms of the speed they could achieve - something a lot less than what they could support.
you can also right click the task bar, click task manager, performance tab, then memory tab, and it will show you the speed of your ram in MT/s. anything else under this performance tab like the cpu can be off. ie the speed and load of the CPU can be off by as much as a couple hundred Mhz and reads hi by 10% of more.
@@PE4Doers You as well, I Did not know the exact process, but your video instruction was very clear and precise, one system i put together a couple of years ago plugging in ram and trying to get XMP to work , i stumbled threw it only cause that mother board was just about the cheapest i could find for one of my Pc's ie anytime changing ram, you had to short the Cmos pins just to get back into the BIOS anytime plugging ram sticks in. I past your video link onto a couple a friends already, as your presentation is perfect. Thanks again, Happy Holidays
Sorry , I forgot to add the reason why ram speed drops when using 4 dims is, the communication path to A1 and A3 loop through B2 and B4, by the time the signal gets there and back there end up being to much noise in the circuit to be able to operate at the higher frequencies, this is why when plugging in 4 dims, the Mother board clocks the ram sockets down to the lowest speed it can, so is to have a bootable system. This why the New CUdims can hit 10,000Mhz and higher as the dimms have frequency amps and filters on them. Ie the New 1851 hi end Mother boards
I found if I don't do that, then the memory training not only takes longer, but it actually makes mistakes that lead to a Blue Screen withing a few minutes of running any version of windows.
Check in msnual of motherboard, which DIMM slot is read at boot, typically AMD Zen5 seems to look up A2 and B2, since infinity buss is clocked at 6000mhz, getting DDR 5 6000 makes a lot of sense. Low latency ram will also benefit gaming by up to 10%. Also make sure onboard NVMe is not bus split with PCIe slot.
With the Z790, whenever you load-up all four slots there will be timing issues. That is why I limited mine to a single pair bringing the total up to 96.
This is good; However my understanding is that to get best performance from 4 sticks you need to get a "four stick kit" i.e 4 x 32 or 4 x 16 -- combining a pair of two stick kits is not the best.
I have heard that as well, however those kits are somewhat rare and quite expensive (>800.00$ from one quad kit I recently priced). Also, there are different opinions on that, with the majority believing that the current memory controllers are just not up to the task yet to size for the higher frequencies. With "Moore's law" however, we should be past that within the next couple of years with the newer CPU's and new motherboards.
@@PE4Doers I actually have a live example of this -- in a threadripper machine; where a single 4 stick 64GB kit of CL16 3600 RAM runs at its full xmp rated speed, however on adding a second identical kit, machine only booted successfully when I dropped frequency to 3000 (lower even than 3200). But yes a full 128GB kit of 8 sticks would have cost north of a thousand bucks 🤨🤨
