Hello. I want to buy a X170KM-G without CPU and without SSD. Want one with: 16GB of RAM maximum. RTX 3060 maximum. Dual 330W or 780W PSU (can pay +80usd extra for it) Can do 750USD PayPal direct quick payment. Shipping can pay 150USD for Canada/USA Shipping can pay 30€ for Europe It's to test my RTX 4090 MXM. I do need to get the custom heatsink for it and it'll cost more like 300USD...
-
The test was the Dell Precision M6800 (x8) vs P775TM (x16) in TimeSpy graphics only. Maybe the Dell is too old for the 4090 but good for the 4080. (16100 graphics) 330W PSU minimum for both systems.
-
Me too I don't need inf mod. It's not important
-
64GBPS (x8) vs 128GBPS (x16). X8 runs great on 4080 but on 4090 I get 4080 performance, maybe I did something wrong there. PCIe 4 x8 = 3 x16 PCIe 4 x4 = 3 x8 (Oculink speed)
-
P870TM only does PCIE 3.0 x8 for one slot. And the GPU heatsink will cost a lot lol
-
In Passmark, the average single thread performance is higher on the 11900k than the 9900k. 9900k 2800-2900 vs 11900K 3400-3500 In gaming not so much difference other than the high wattage on the 11th gen CPU for 5/6FPS gain... While being on the same 14nm node... For the heatsink mod. I'll just do one straight heatpipe connected between the CPU and GPU for a shared cooling design. Without adding a 0.5mm copper plate since I'll remove 3 of the tiny heatsinks on the CPU heatsink. If the first heatpipe is enough, I won't add a second one.
-
So at 4.7GHz and 4.8GHz all core, which CPU does the best (in terms of temperature) at the same clock speed? I'm interested to get the binned 9900K which is the 9900KS. Or should I just ditch this laptop and get the X170KM with 11700K?
-
So for example The 9900K/9900KF => 4.9GHz all core thermal throttle The 9900KS => 4.9Ghz all core no thermal throttle? Can the laptop handle 5.0GHz all core without any thermal throttle?
-
Is the 9900KS running at 5GHz all core at 140W? Is it better than the 9900K/9900KF since it's highly binned? Meaning we could do -130mV undervolts? I made my backlight mod v2 (with brightness control) work on this P775TM laptop and I got the custom heatsink from Cicichen. Can get 54k graphics points in Fire Strike.
-
Yes the CPU speed does give extra fps in heaven benchmark. Tested with multiple CPU configurations and overclocking helps a lot. I get max 160W on the CPU when I use ThrottleStop and TimeSpy bench I used thermal glue 2w/mk, the best one that sticks very well. Some videos on YouTube, people used that thermal glue on the edges + used some thermal paste in the middle of the heatpipe and it was effective for them. I wanted to use a copper plate to elevate the heatpipes since there are some tiny heatsinks on the right of the heatsink
-
Thanks. The heatpipe improved my TimeSpy score from 9.7/9.8k to 10.2/10.3k. so it does something. 4.9GHz all cores, -80mV I ran Heaven benchmark, it uses both CPU and GPU at the same time. GPU max temp was 80C and 88C in the hot spot. Got 390FPS in 1080p Ultra, no thermal throttle on the GPU. So can I just: use a 0.5mm thickness copper plate, glue it on the 3 CPU heatpipes and glue one straight heatpipe on top of the plate, all the way to the bottom GPU core side? I can improve my clocks if I do this.
-
The heatpipe does work. I did the hot water test. What are your settings for 9900k? Core? Undervolt? PL? Can I just use one "red" heatpipe then? It'll improve in both cases (bench, gaming). I think one straight copper heatpipe at 10-12cm equals to 50W of heat.
-
Which option is better for cooling? My GPU temps are extremely good in TimeSpy and I was able to get 20.1k with the RTX 4090 MXM. The problem is the CPU temps. Can I just: leave the "yellow" curved heatpipe or Remove the "yellow" heatpipe and add 2 10cm "red" heatpipes instead?
-
Hello does anyone make RTX 40XX MXM-B heatsink for the X170KM? (need to change the X-bracket offset) I want to know that before I buy one and replace the P775TM. @rainer124 @Maro97

Hello. Indeed these have a MXM slot and a big heatsink with 3 big shared heatpipes. The max CPU is 13900HK. The motherboard looks very poor quality with only 1 NVME slot. All of the HDMI, USB-C and eDP outputs are routed from the iGPU and not the dGPU! That's so unfortunate... They are selling the laptop without RAM for 600€ with i5 13500H and MXM RTX 3050. I thought it was the best MXM laptop but no, the best ones are the P775TM and X170 series from now...
