Hi guys,
dunno if this was discussed somewhere else in the forum but i could not find anything so I'll take a chance.
  1. I'm struggling to get right a couple of things with this new laptop. First of all, I’m running the 2 x 32 GB Samsung memory stock option. These are rated DDR5 – 4800 but just run DDR5 - 4000 at start up. I’ve been browsing on the net and found that one has to manually set them to run at 4800 Mhz. All good with that, I’m quite ok to adjust parameters my self but here are my questions:

    1. 1. I noticed that no XMP profile comes up if you would want to set up the memories to 4800 without enabling the “overclocking” option. IMHO this should be your ”option 2” if memories do not boot up simply switching to their XMP profile. Is this because these RAMs do not support XMP or is it because the laptop/bios is not supporting such profiles :unsure:?

    3. 2. Once memories are set to DDR5 – 4800, laptop would start-up just after a 1 min delay :shocked:. Now I read on-line that this is unavoidable but I’m struggling to understand why this is happening. Is this because of the stock Samsung RAMs, meaning if I go for instance for G.Skills Ripjaws DDR – 5600 I’m not going to experience this delay? Or is this like a safety feature embedded in the BIOS to avoid getting stuck with a not booting laptop? If so, can that be circumvented in some way?

    5. 3. I wanted to play around with timings of these RAMs but I’m not very sure about the BIOS auto-reset to default settings/last working settings should the laptop not boot. For instance, my previous Eurocom Sky 7 would reboot to last working config if it was failing to boot on new config. Is this happening also with this laptop, or you got to use the “hard reset” disconnecting battery and flushing remaining power through the power up button every time that laptop is not booting up in a specific config?

    7. 4. Last, but not least, I’m planning to upgrade to G.Skills Ripjaws DDR – 5600. Not sure if a 2 x 32 GB set would be supported at those frequencies though? Do you have any idea?
Thanks for your help, looking forward to hearing from you.

Have a great day! :-)
 
I have the exact model laptop and i think you can only install SODIMM ram, and from the sounds of it, that sounds like normal desktop ram. Also i think the motherboard in the GT77 is limited to 4800mhz so that extra speed is a waste even if the ram fitted and worked which i highly doubt it would. Bought this myself last week but havent had a chance to install it yet Crucial 64GB 2X32GB Gaming RAM DDR5 SODIMM 4800MHz For Notebooks CT32G48C40S5 649528906526 | eBay . But that is the type of ram you need to purchase to upgrade whats in there, not the g.skill type
 
Thanks, appreciate the reply however SODIMM RAM is the standard form factor for laptops.

I did not specify but...I'm going to buy SODIMM G.Skills Ripjaws DDR – 5600. ;)

Let me know if you can pick up their XMP profile from bios please?

Have a great day!
 
Hello, for the second point, there is a way to make it boot faster. You have to disable Watch dog Timer in the bios. But then, the laptop will fail to boot if you change the voltage of the CPU and you'll have to press the power button for 30 seconds to reset it. What I did then is to undervolt from Windows

> The laptop support 2DPC so the memory frequency should be DDR5-3600 if your memory is with two ranks. It is limited by the processor. It is suggested to use the original RMA which is bundled and restore XMP setting.

Not at all. This table shows that with a 1DPC configuration - 1 Device Per Channel and a 2R typology of Ram (32 GB stick) one should be able to hit 5.200 Mhz. This is exactly my case... 1 x 32 GB memory stick per channel.
What am I getting wrong here?
 
Even if the corresponding slot is not populated? As far as I know that is if you have all the slots occupied?

Maybe I'm getting it all wrong but then...Why was I able to run the stock Samsung 2 x 32 stick at 4,400 MHz?
