-12mv UV CPU / +250 Core/+500 Mem GPU. It doesn't necessarily mean dropping clocks, but some people opt to to hit a certain power target. Kelton_Page April 12, 2024, 2:20pm 34. It's undervolt algorithm seems to let you boost higher compared to GHelper which alot of ASUS laptop owners use. I haven't played around much with CPU undervolting, other than finding out my 7940HS/RTX4080 G14 will crash quickly at a -25 CPU undervolt, and is slightly unstable at a -20 CPU undervolt (doesn't always make it through a Timespy benchmark), but seems stable at -15 - buy I've not really tested out much whether there is much benefit from doing this. 13900H is pointless. At 35 watts, the new Zen4 chip did even better - almost as good as the Apple M2 Pro even. trying to choose between the 2. With undervolt settings in Octanebench it uses around 250-270 Watts Guys dont undervolt too much. CPU Boosting you need to check your undervolted cores can keep boosted status. From HWMonitor, I seem to understand that I can overclock the iGPU to 3Ghz under Adaptive Mode. 0 GHz / 5. If it ever crashes or has issues (possibly in the mid 20's near the -30 limit), then just lower it a bit and see if its fully AAAAGGGHHH 2023 Zephyrus G14 (ryzen 9 7940hs and 16g ram and 4060) OR Legion Pro 5 Gen 8 (AMD Ryzen™ 7 7745HX and 32g ram and 4070) Model 2023 like the title says. PS5 has 2304 cores, 144 TMUs, 64 ROPs, 16 GB VRAM. You can undervolt the 7940hs using Universal X86 Tuning Utility. 5hrs! I wonder about the turbo mode. 80 is as cool as it can be. I would run cinebench on stock, keep that score handy, and compare it with your undervolt. Open up CPU-Z and HWMonitor, check your current voltages and temperatures while running a CPU benchmark, and write down the values. One note, ONLY run this plugged in, it will eat your battery. When buying the 7940HS for the few % performance improvement, I don’t play the lottery neither. Loses out to the 7840u on average even when it draws similar or sometimes higher power When taking the geometric mean of all 370 benchmark results, the Ryzen 7 7840U enjoyed a 28% lead over the Intel Core Ultra 7 155H in these Linux CPU performance benchmarks. I see that it was a short boost because it ran for one pass, but it is still very impressive. Best way to do it is run Cinebench with HWinfo open (helpful to have graphs open for CPU clock speed, CPU temps, and VID voltage). The Beelink GTR7 is 7840HS and the GTR7 Pro is 7940HS. So I had hoped to be able to tweak a bit with UXTU. Its odd though that if I change the power management mode from Normal to Prefer maximum performance. Shocking insanely expensive, rip G14, same price as a razer now insane. Screen is 2k res 350 nits 100 SRGB. I basically gave up on it. Zephyrus G14 2023 - 7940HS - RTX 4060 - Undervolt + OC + RAM Upgrade. Apply your setting. Op is looking at the hs chip which is monolithic and more of a competitor with the 13700h. Add another ram stick as soon as you get this one. You get the following controls for the CPU: slow (sustained power), fast (2-second peak power), undervolt, and temperature threshold. no bluescreen/reboot. Temp maxing out at 96C. I have the 7940HS cpu and 4060. Problem is that sometimes you need boost on just 1 core and this caps your max performance. Now for a few benchmarks, I did Tomb Raider and Cyberpunk both on absolute max settings with RTX at full or insane settings at 2560 x 1600 which is the native resolution of both panels. 2GHz higher than 7840HS in base frequency, and only 0. Use an egpu solution when gaming. LittleMiracle-. 5" notebook.

Overall AMD is actually the better performimg CPU for gaming as well. Your CPU score is lower than I'd expect for the undervolt as well, here's my recent turbo/ult score with stock settings. It should run at 80w in turbo mode but it runs at 40-50w at most. Alternatively lower the brightness when not needed (you're using it indoor for example). Very insane pricing, unfortunately they may be able to get away with it as it is the best 14 inch gaming laptop, speaking as a 2022 model owner. Do testing with like timespy, heaven, games, wtvr. I've only ever undervolted desktop GPU's (I have a 4080 that I UV using MSI Afterburner), but I've never undervolted an AMD CPU. So i undervolted my 3090 with MSI Afterburner and it works when i do Octanebench. That would mean that you "only" get around 10% performance with the 7940HS and the 4060. Therefore you under volting your CPU or any other components in tha Lenovo laptop, is not practical or even possible, in my view. This is likely why u/Every-Satisfaction74 experienced slower than stock performance. 10 booting using a longer process that returns the oem 6. Consider buying a processor that can be undervolted, I made the mistake of buying a laptop with an 5800H which can't be undervolted and temps go sky high, consider an HX or 7940HS never runs at full power (max 50w) Model 2023. No frame generation or DLSS modes were used, HDR was turned off. Use XTU to undervolt. Sorry, this post was deleted by the person who originally posted it. I know this is Overclocking subreddit but I thought you guys should be more knowledgeable about it. Conclusion: In the CPU-Z single-core test, 7940HS (54W) scored 5. Max temp for 1st and 2nd pic was 95-96C but the one with the undervolt had about 100-150mHz higher boost clock which raised the cpu score by a nice margin. My first impressions are that the Blade 14 is one very premium laptop--pretty much in a class of its own, since no other 14" gaming laptops feature a unibody aluminum chassis this year. This shows that the new HS CPUs are happiest at 35-55 watts The M16 is so noisy its unusable on Turbo, the G14 is actually quite usable on Turbo. CPU does -23 CPU undervolt on GHelper using Efficient Aggressive power mode. 47K subscribers in the MiniPCs community. For the multicore bench, CPU core clock settles at ~4750 MHz @ 1. So this actually decreases the temperature as the GPU is hitting higher clock-speed at lower voltages, hence greater efficiency. OP • 10 mo. Go back into Ryzen How can you get the best temperatures, fan noise, and performance out of your RTX 4050, 4060, 4070, 4080, or 4090? I got you!
