These are some informations I figured out at SK Hynix to tear down their model numbers.
When we're looking at the Samsung Models, we'll see that there will be 32GB Modules, but ( if I read the chart correctly ) they're double ranked instead of single ranked like the 8GB or 16GB Modules. 🤔
But what will this mean to us ? Seems to me that the 8GB and 16GB Modules are single sided and 32GB modules are double sided. @MasterC can you eventually confirm this ? As I remind me correctly the double sided modules are using as a kit the full 4 bank bandwith while single sided modules are only using 2 banks in kit configuration 🤔 This could be a possible solution for running the bigger modules only at 4800MT/s. I don't know if there's a posibility to get single sided 32GB modules in the future or if this option isn't technicaly realizable.
Otherwise it would be a nice option, to give us access to the XMP Profiles in BIOS.
@MasterC on which BIOS version have this been testet / confirmed to run these modules at 5600 MT/s and what have you done to get these modules to run at this speed ? This would be interesting.
Just buy it from TMALL (Taobao) -
"PS: for those who wants to use 2x32GB mudules (dual rank), please note as per intel specs they will run at 5200MHz only, not 5600MHz which is supported officialy only with single rank modules." - where did you get this information? Is there any official document published to confirm this? here is intel info on their ARK page about i9-13980HX:https://ark.intel.com/content/www/us/en/ark/products/232138/intel-core-i913980hx-processor-36m-cache...
Dear @Kogashjne
I don't know where to get Intel specs about 5200MT/s 🤔 https://ark.intel.com/content/www/us/en/ark/products/232171/intel-core-i913900hx-processor-36m-cache...
The specification of the i9-13980HX tell us, that there's support of 2 channel dual RAM banks.
Even if we look at the specs of the HM770 chipset https://www.intel.com/content/www/us/en/products/sku/232478/intel-hm770-chipset/specifications.html it tells us, that there are 2 DIMMs supportet per channel. In summary this meant theoretical it's possible to build a board with 4 SODIMM Slots ( like Desktop Mainboards that also use 4 DIMM Slots ). When we look further to the max supported Memory, we'll see 128GB. If we divide 128GB through 4 DIMMs it's been 32GB per module, right ?
But ( if I get it right ) we run into a barrier known years before, where double sided RAM modules ( like our 2x8 32GB modules ) are getting slightly in to trouble when they are maxed out in DIMM slots. So over the years it was possible to run smoothly 4 single sided DIMMs ( here 1x8 in 16GB ) or alternative 2 double sided DIMMs ( 2x8 in 32GB ) in our 4 channel desktop boards. Meanwhile Notebooks are mostly designed only in 2 DIMM slots, there are still 2 channels per slot which means to us, the RAM is running in dual mode on two channels which gives us quad channel support. This could have be an effect on the performance and timings where manufactureres doing some testings and work on the QVL list where some explicit modules been tested to work propper in their systems. If you're looking to some desktop mainboard QVL's, you'll see that some modules are running in full 4 DIMM configurations meanwhile some are only support 2 DIMM max.
When we get into touch with our notebook systems here this means to me, that there must be a fully support for 2 double sided RAM modules while knowing the specs above ( which it does seeing the screenshots that saying Quad Channel ). And therefore it doesn't matter if these are 4 single sided (1x8) oder 2 double sided (2x8) modules. 😉
Let's take a look at the chips on the modules themselves. Like I see you're now using Samsung modules with Samsung chips and you get slightly lower timings on your 634JZ then mine SK Hynix on the Kingston modules in my 834JZ. I think that depends on the controllers and chips used for these RAM modules including their programmed timings. If we read some intersting articles about the chips themselves, the newer A-DIEs have a slightly better performance then the formaly M-DIEs from Hyinx. That's the reason we can actually find up to 8000MT/s in XMP Mode for desktop modules. Yes, this is way to much for a laptop, not possible without a headspreader or cooling and also only for overclockers in the desktop sector, but these chips are high in performance and can do this job. Yeah, I know... Comparing Notebooks and Desktops isn't the right way ✌️ But, if our desktop CPUs have the same DDR5-5600 spec then our notebook CPUs, why is it so hard to get the RAM doing it's work in full performance mode in our notebooks ? I can't find the clue in this.
https://www.intel.com/content/www/us/en/gaming/xmp-3-for-core-processors.html?wapkw=XMP%203.0
I don't know if this helps, but there's an "older" RAM Kit listed in Intels XMP3.0 List ( on page 2 for mobile CPUs ) with 6000MT/s on an i7-12700H which officially only supports 4800MT/s 🤔
So I still wish that ASUS is working on that and eventually give us the XMP Profile Option ?
Last thing: The automated update option via seperate download or MyASUS is a nice feature, but can someone please explain the real update features made in the different BIOS versions ? Since 302 the only information we get in the infobox is "optimized system performance". What does that mean in detail ? Some users talking about less coilwining since version 308, but how ? New BIOS version of nVIDIA chip ? In this case I would prefer a bit more information 😉👍
Thank you for reading and please keep us updated.
If I get wrong in any case of my thoughts, feel free to correct me. TY
