Made some progress with the 7945HX3D. I have it running at 1.35V now and copied the XMP profile primary timings and calculated a few others based on guides I have found. I am unsure how SODIMM effects what A die can do but at least this is 1DPC. Notes: SoC/Uncore OC Mode - SoC/Uncore OC Mode - enabled (VSOC higher voltage, FCLK/UCLK static) Onboard voltage control - vddio voltage control - vddio Ctrl - manual - dimm vdd adjust - 1350 (sets VDDIO+VDD+VDDQ) - enable platform pmic control - disable (prevent EC adjustments?) DDR and infinity fabric frequency/timings - infinity fabric frequency and dividers - infinity fabric frequency and dividers - 2067 (2133 stable but not 2:3 ratio) - uclk div1 mode - uclk=memclk (have not tested memclk/2) - DDR options - DDR timing configuration - active memory timing settings - enabled - memory target speed - 6200 (6400 unstable) - DDR SPD timing - tCL - 0x26 / 38 (from XMP profile) - tRCD - 0x26 / 38 (from XMP profile) - tRP - 0x26 / 38 (from XMP profile) - tRAS - 0x3e / 62 (tRCD+tRTP) - tRC - 0x66 / 102 (tRCD+tRP+tRTP+2) - tWR - 0x30 / 48 - tRFC1 - 0x193 / 403 (130ns from RFC mini chart for hynix A die)

This is the MSI Raider 18. Its 1DPC just like all of their models this year so it should do better with memory tuning if I put in the time. The OEM SK Hynix kit has very loose timings, CL50 at 6200. I should probably switch over to the better 2x16 Kingston Fury 5600 CL40 kit before starting. I also have their 6400 CL38 XMP kit but it may not offer any advantage here if voltage cannot be adjusted.

Nice to see some numbers. I guess going from 4080 Super to 5090 would still be a decent boost but I think my cutoff for return is actually Jan 26th so I will have to decide if I will gamble on finding any card that would be an upgrade. Your testing of the 5800X3D got me interested in the 7945HX3D again. Pushed it to 6200 MCLK + UCLK / 2066 FCLK this morning which passed TM5. 6400 / 2133 would not boot. I need to find a zen4 tuning guide so I can figure out where to start with tuning that. The Kingston Fury 2x16 Hynix kit seems to select functional timings from the start but they are much worse than the same kits on desktop. It seems like VDD / VDDQ also cannot be adjusted from 1.1v on this platform either so that may be a limiter.

I do think the Raider A18 is better than the other 18 inch options and the pricing was much more sane than the Titan 18 while also being better equipped for gaming than the Intel Raider or Titan 18. It could probably be perfectly fine at Ultra 10 with RT in WoW.

I usually have settings at 10 ultra with RT. I have not tried TWW outdoor raids. Will need to do that. 5080 seems like it should do better than a 4080 Super I think. The 7800X3D + 7900GRE was just not a performance boost much beyond what laptops can do. The MSI x670e tomahawk also kept dropping my m.2 drive. The 7945HX3D is better but it's capped to 100W courtesy of AMD. There are a few other bad bugs like the audio system dropping out until a reboot. It is one MSI system where silent mode actually works and quite well. 55W on the CPU and 100W on the GPU is enough for a good experience given the quiet fan noise. The new steel series controller is also horrible because it has a rainbow RGB boot effect and cannot remember an override. A have read a lot of posts on Reddit and whatnot about people excited for 9955HX3D but it's going to be a poor product if its buggy like this and artificially capped. AMD apparently has to play a bigger role with bios development on these machines so you may as well not consider it being a typical good unlocked MSI laptop bios.

I found the 4080 Super was generally doing ok even in some outdoor raids (those 20th anniv. world bosses). It did not fall below 50fps generally. That is with CPU at 4.8ghz, mesh at 3ghz, memory at 6400 CL32 and only using a QHD display. I do not think I would want to go back to a non-HEDT chip. I did not like the 7800X3D and the 7945HX3D is equally unappealing. 14900K and even a 285K would be to close to laptop offerings so I would just use a laptop again in that case. I guess at least the desktop GPU's (5080 or 5090) should not really devalue that much so if I go through the trouble of getting one it would not be a big deal to just resell.

Would you say upgrading from a 4080 Super to a 5080 or even 5090 would be worthwhile for WoW? In theory I could push core clocks up to 5.2ghz on the Xeon but I am not sure how far it could go beyond that so there may be a CPU bottleneck. The 4080 Super I currently have was $1029 and can be returned to Best Buy until Feb 1st.

Info is starting to trickle out about the Schenker Key 18 Pro. Still no photos of its cooling system but it is a start. https://www.techpowerup.com/330672/schenker-xmg-shows-off-laptops-featuring-geforce-rtx-5090-laptop-gpu

I think 2xSODIMM is actually an upgrade for the Titan 18. These are the 24GB M-die sticks that should go into it as well: https://v-color.net/products/copy-of-ddr5-specifications-so-dimm?variant=45911957373095 I am disappointed to yet again not see QHD+ 240hz in the specs here. It was a joke in 2024 that it took 9 months for them to actually release a Titan 18 config with QHD+ while they very well had panels available at day one.

The key will be if they decide to use better cooling on it than the X370. I have compared the PE60SNE with the X370 and it is significantly better just by having a vapor chamber instead of heatpipes. It also needs better M.2 cooling and ideally would be compatible with RAM cooling upgrades as well. It also could use better speakers as the 2x1W solution on the X370 was barely adequate. Because the motherboard has four memory slots it will not do as well with 2x16GB, likely capping out at 6000MT/s even with the best SODIMMs. You can see a photo of the backside of the X580 on Clevo's site now too: https://www.clevo.com.tw/product/product_list/1

The X370 has serious issues with overheating compared to the X170. It cannot really sustain the advertised 250W combined loads and even when it does the excess heat bleeds into the RAM heating it up over 85C and the audio AMP causing distortion in the speakers and headphone output. Clevo has a smaller model, PE60, that has a better cooling system and can properly run its components at advertised speeds. That is their true flagship model, it just tops out at 4070 mobile, but is a good complement device to a desktop as it turns out. I do not think we will get any full socketed models in the future. BGA HX chips exist from both AMD and Intel so its going to be the path they provide for these laptops.

I think the RCD chip on the memory adds 20-30ns latency. It is clocked at 6400 CL32-39-39-84. I think 6800 or even 7000 may be possible. I know its not as good as a 14900K can do but it is the price for having over 8 P-cores and no e-cores, while not being the AMD option. I will submit a full report to Finalwire. It would be nice if it could detect everything properly.

I am testing mesh at 3ghz with 1.065v. This is what I progressed with so far: 24x 0.905v 25x 0.925v 26x 0.945v 27x 0.965v (failed) 27x 0.975v 28x 1.005v 29x 1.035v 30x 1.065v For some reason setting a Cache offset voltage over +5mv in the bios causes hwinfo64 to BSOD when starting up. I checked the existing VF Curve for cache and from 18x to 23x it added 20mv for each step as reported. I checked AIDA64 a couple of times as I was progressing and memory latency seemed to benefit along with L3 bandwidth and latency as well. In games 3ghz feels more responsive and has little to no frame rate dips any more (that chunking effect Electrosoft mentions in WoW). One other guy I found mentioned that 30x mesh was stable for him at 1.08v, but he was not able to get 31x or 32x stable.

Well, so far I am trying to boost the mesh by increasing 100mhz and 20mv steps and let it run an hour of y-cruncher component test for stability. One nice thing about using the P5800X as a boot drive is that since it does not use a cache it seems like BSODs do not easily corrupt the OS.
