Configuration overview
The configuration of this MSI Titan GT77 HX 13V is based on an Intel Raptor Lake platform. The CPU used (I9-13950HX) is a version of the I9-13900K found on LGA desktops but adapted to BGA laptops.
The different components :
We start with the CPU, motherboard and RAM, here on CPU we can see that the GT77 is equipped with an I9-13950HX mounted on a HM770 chipset motherboard. For RAM, the sticks are 32 Gb for 64 Gb of RAM in total, we are on Samsung B-die modules in dual rank at 4800 Mt/s CL40. Well, that’s on paper, because in fact a problem with the bios makes the RAM run at 4000 Mt/s CL32 and the PC thinks that slots 1 and 4 are filled.
Let’s move on to the graphics card. Here, we are on the most powerful for a laptop. Indeed, the RTX 4090 mobile manages to match a desktop RTX 3090 without any difficulty. It has the same chip as the desktop RTX4080 but with lower frequencies and GRDD6 memory instead of GDDR6X.
For storage, we have two Samsung PCIe 4.0 x4 in Raid 0. The use of Raid 0 allows to reach very high data rates while keeping a large capacity.
As for the screen we are on a Mini-LED IPS 4K (3820x2160p) capable of reaching 1000 nits in HDR.
Disassembly, repair and upgrade:
Disassembly is done by removing the 8 screws on the back of the device, you will then need to use plastic tools as in the ifixit kits. For any modification or manipulation, it will be necessary to disconnect the battery, especially for the change of the DDR5 which dies rather easily if always fed in 5V.
From a modification point of view, we have easy access to the 4 so-dimm DDR5 slots but also to the 3 M.2 slots in PCIe 5.0 and 4.0 x4. The Wi-Fi card is also easily accessible as is the cooling system.
