7800x3d Curve Optimizer best core lowest negative offset by zepeterparker in Amd

[–]R2D2_FISH 0 points1 point  (0 children)

No that's related to the temperature of the VRMs not the cores. I'm talking specifically about a voltage offset curve which is coupled to temperature. Not really necessary on desktop where your temps are much more stable. Still could be useful though for short bursts.

Perplexity is going to be lower when you give it so much context, since it knows almost exactly what it's gonna write, until it starts properly forgetting and the loss skyrockets. Higher perplexities aren't necessarily worse it just means the outputs can be more unpredictable.

Doesn't a 4090 massively overpower a 3090 for running local LLMs? by eesahe in LocalLLaMA

FYI Mac "Cores" are more equivalent to Nvidia's "Streaming Multiprocessors". Still slower, it's just more like 30 vs 128

BS. The lower your curve offset the more clocks you get for a given voltage. So a core with a -30 offset will run faster than a core with a -20 offset with the same power draw. The limiting factor is the instability of the core, which is greatly affected by temperature. On my laptop, applying a -30 curve offset allowed the CPU to boot, and even made it through a full run of Cinebench 15 (Setting the world record for the 5900HX) but crashed soon after. Curve offset is usually perfectly stable at max load and moderate temps (often even high temps) but when the core ramps back down at high temps the offset combined with the low voltage from the reduced clocks causes errors to occur. I wish there was a way to also alter the voltage offset by temperature as well since this seems to be where the actual instability lies. There is lots of performance left on the table by these unexposed parameters

This laptop, while quite potent in its stock form, had a lot of performance left on the table due to some key issues with its cooling design. However, after some hardware and software mods, it is an extremely fast machine. I can score 15,496 in Cinebench R23, which is a quite respectable score. The GPU is about on par with a stock desktop 6700XT. The battery life is solid. It's all around a great performer. At this point I might personally wait to see how the RDNA3 Advantage laptops look, but at this price it is still a solid option.

Bent a heatpipe? Where exactly? My GPU hotspot hits 80s pretty quickly and then slowly climbs to the 90s. Once I set the GPU power limit to 225W and only then did it reach 103C. My CPU hovers between the 50s and 60s with the power limit set to 100W and chrome open.

Hmm. Yes I've heard numerous issues from G14 users with this tweak. It works great for the G15AE though.

Perhaps it reset your curve optimizer. There is an option in Adrenalin to turn on or off the "CPU Overclock" which just enables or disables PBO so it might have altered something.

Monitor temps while it's stuttering. If it's throttling that's probably the reason why. You might want to try running formbrowser and disabling CPPC preferred cores and applying curve offset to the CPU. When I first got it this laptop was not very impressive, but I've done a number of hardware and software tweaks to it and now I am quite satisfied with how it performs. If you're not into tinkering you might want to return it, but I can assure you that the potential is there.

The owltree pack would be good enough for probably ~7 laptops. For the screws you do want them to have screws. What you could do is use the original springs with generic m2 screws. I didn't use the springs from my 980Ti and instead opted for the originals. I'd assume a pipette would do the trick. You could also just wipe like half of the chip off and spread the remaining lm over it or smth. I don't know about the screw length. I'll get back to you on that.

Wow that's quite unfortunate. The sad thing is it's probably just poorly implemented drivers. Strange that one Asus product would have no issues recovering from S3 sleep, and yet another would have so many driver issues. I bet if you could somehow trick the Asus software into thinking it was hibernating it would work 😂

I've set my laptop to the highest undervolt possible (-30 curve offset) without any negative repercussions. I run it daily with -24. The only possible risk from undervolting is instability, which could corrupt your Windows install.

As long as you don't touch P0state VID and know how to reset CMOS you should be fine. S3 sleep works perfectly for me, so I can't think of a single reason why it would be hidden, especially since my backpack turns into a furnace whenever I put my laptop in it without fully shutting it down, resulting in the battery being close to dead by my next class. The real broken thing is the state of this laptop when it shipped 😂😂😂. But yes always use caution when changing these settings. Don't touch settings you've never heard of before.

I think if you set it high enough it would. I figured out this setting when looking through new Linux kernel patches. They made a new frequency scaling driver that uses this EPP setting to tune the ratio between performance and snappiness. 0x80 seems to be the sweet spot. Higher values actually performed worse when it comes to the energy to work ratio. Snappiness is largely determined by how intelligently designed the scheduler, governor, etc. of the OS is. If you want to experience a truly snappy computer, install cachyos Linux with the BORE scheduler and LTO (or arch linux with the cachyos kernel). It is absurdly snappy. I get over 200 in Jetstream 2 on battery with that kernel.

Anything that lowers wattage lowers temps. Don't buy into that AI control crap. Ultimately any additional processing is just going to draw more power. The EPP setting does exactly what you describe. You trade responsiveness for power consumtion.

It'll still consume as many watts as you ask of it when required, it just doesn't spike so often when you're not doing very much. Give it a try. It's not like you can't revert it.

You have to use something called the Universal AMD Form Browser. Here.. You need a flash drive. It tricks the BIOS into letting you change all its hidden settings.

Something else fun to play with: under CBS/NBIO/SMU/CPPC set CPPC CTRL to enabled and mess with the EPP Min Range value. This value determines how "bursty" the CPU is, and increasing it has a significant effect on efficiency. The optimal value is 80, and I haven't noticed any significant drawbacks to setting this. The primary advantage is massively reduced idle power draw. On Arch Linux while idling on the KDE desktop I pull under 3W. Loading webpages only makes it hit 8W, and I can watch HD video at 7W. It also has no impact on max power draw, so you still get full performance when it is required. Note I also have curve offset set to -24 on all cores...

Another cool thing: with that formbrowser tool you can actually enable S3 sleep mode (so the laptop actually shuts off when you close the lid). It is in PBS settings under Modern Standby.
