I want to upgrade ROG Strix G18 (2023) RAM to 5600mhz in BIOS

I want Asus officials to support this issue. I want to upgrade ROG Strix G18 (2023) RAM to 5600 mhz. Please do a bios update for it. Other brands allow up to 6000 MHz.

Good day friend, Ive had scar 18 4090 2023. From factory was installed 4800 32 gb. I bought 

 

Kingston SODIMM DDR5 64GB (2x32GB) 5600Mhz FURY Impact Black (KF556S40IBK2-64)

But I cannt make undervolt via bios, because if I will make long reset (push power buttons 30 seconds) will be boot loop.

 

All stress test passing well, last bios is installed. 

 

 

 

Generally I found that stock 32 gb 4800 and presebt 64 gb 5200 didbt give me any extra fps in games or scores in tests(

 

but another asus laptop, when i updated from 16 to 32 gb, from 4800 to 5600 I recived some increase prod

uction 3-5%

I am sorry but i am sick of these things to get 1% but i always upgraded my laptop to maximum i could when it is brand new. I was not happy with 5600 that is why i am back to 4800. I am not a gamer at all but i like to have my laptop as best as it can be. I dont like troubles to deal with anymore i am almost 50 but when i was young i was doing everything to get 0.5% more 🙂 

maybe You have problem only due to malfunction and some problem on yours 5600 memory(

that is also possible but i am tired to try. I paid about 400 euro when they were new and now they are useless:) I dont have time to deal with these things anymore like before. I left them at home, i may try them later in the future again or replace them under warranty i dont know. But thank you for your kind help

Keep in touch.

P.s. better to disconnect buttery for replacing memory

I did forgot that trick though. So when i am back home i will try. Thank you again very much.

Hi @captainseko,
it sounds to me like you've the same mindset as me and as we're both near to the age of 50 we had a long experience with all the memory stuff from SD-RAM, DDR, DDR-2, DDR-3 DDR-4 and now DDR-5. As you know DDR is meaning double data rate, so when it came up to the discussion about "performance" we've to take a look at the whole RAM module. Beginning from the real clock which is half of the MT/s which means 5600MT/s is 2800MHz, 5200MT/s is 2600MHz or 4800MT/s is 2400MHz.
The second thing about RAM performance is still the CAS latency ( CL ) which describes the time the RAM can be filled with new informations. In fact: the lower the latency the faster the RAM. This is in comparsion to the higher frequencies. The higher the frequency the faster the RAM. But within electrical issues and / or limitations it isn't possible to get higher frequencies AND lower latency. So when your freqency rises up ( from 4800MT/s to 5600MT/s ) the lantency will rise up, too ( maybe from CL 36 to CL40 ). This will end up in a nearly close performance state and will work the other way, too. Lower latency is only possible with lower frequencies.
So as we know that it just depends on the the silicon lottery and the programming of the RAM manufaturer to max out both factors.
As we know the 3rd factor came out if we're talking about bigger sized modules ( 32GB+ ) which are double ranked and therefore only supporting lower frequencies ( only 5200MT/s instead of 5600MT/s for single sided modules ) but in the same way the latency came down a bit. For example we take a look at the 64GB Kingston Fury kit which is discribed as 5600MT/s kit with CL40 from manufacturer site. But while Intel is only supporting 5200MT/s on double ranked modules our system is recognizing and supporting this kit only with 5200MT/s but with a slightly lower latency of CL38.

So there are many more factors which have to keep in mind and to take a look at when you still want to squeeze out the last performance drop out of your system. For that you can simply take a look at a simple programmed calculator you can find HERE to compare the expected performance increase or boost to your system. What's not included are the pro and cons of the different RAM sizes you prefer depending on your software, workload and needs or favorisation. These are naked numbers and facts for the RAM speed.

So maybe this could explain the past experience of @DreamBim when he ( or she ) upgraded the RAM from 16GB to 32GB within the same speed of 4800MT/s modules ( but I think the new modules had slightly lower latencies ? ) or you get an extra boost from the amount of memory. So only talking about the "speed" of the RAM isn't the real solution for maxing out a system. It's like comparing the max speed of a car against the force or power a motor bringing up over the transmission to the wheels on the streets. Therefore we've also different numbers on cars like force ( Newtonmeters NM ), horsepower  ( HP ) or max speed ( max. mp/h or max. km/h ).

Hopefully I could clear some things up.
