Arc B580 testing - some minor issues

[ProjectPhysX]

Hi @YamsSE,

I have a B580 system to test Arc-Power. The B580 is detected (though the name says 11GB, where did the last GB go? 😄).

• ✅ Monitoring works
• ✅ Core overclocking with offset works
• ✅ VRAM overclocking with offset works (is negative offset possible?)
• ❌ Fixed voltage/frequency mode seems to not work due to driver not accepting the change
• ✅ Power limit works
• ❔ Temperature limit can't test as GPU stays below 60°C
• ❌ Fan speed change does not work, no error

Cool stuff, keep it up!

Kind regards,
Moritz

Hey @ProjectPhysX !

Looking into it as we speak. The Vram issue was noted before and is already fixed in an in-between WIP Build. (This was due to a rounding issue which re-appeared between 1.0.2 and 1.0.4)

• VRAM-Underclocking for Battlemage as well as your Mentioned Alchemist Undervolting is still getting looked into - I had my first Sucess with the Undervolting Part, yet didn't get any further on this so far.

• gpuLock and Fan Speed is being investigated right now - Both work just fine under Alchemist, since I still didn't get my Battlemage GPU, I couldn't hardware Verify each feature yet, will be trying to get both working and preparing Release Version 1.05 with possible fixes applied.

Thank you very much for your input and Bug report, this definitely helps to shape the future of Arc Power!

I have a question, I'm using an ONIX ARC B570 and I couldn't find any guide/tutorial on what each thing on the app does exactly.
Does the Power Limit = Voltage Reducer like on MSI Afterburner? (That's the only thing I've used before to undervolt/overclock a RTX 4050 on a gaming laptop before), or is it something else?

I tried the Fan Controller and it worked right away, which is great cuz now my normal temps are 42C(core)/46C(vram) instead of 52C/54C.
I want to try Power Limit and overclock a bit, I don't know if it will work like you would normally do on RTX GPUs with msi afterburner?

This shows on mine too "Fixed Clock/Voltage lock is not exposed for this adapter's native voltage units" which I don't understand what it means.

@KarioTommy That's pretty much as there is no Guide / Tutorial around yet, except the original Documentation.

• Power Limit will work like you think it would on any other Software. +% = More Wattage Budget | -% = less Wattage Budget (So yes a Lower Power Limit esentially will let your GPU use less Wattage.
• Temperature Limit in % aswell as Voltage Offset in % will be fixed in 1.0.6 as they are supposed to be raw values and not Percentages.

Fixed Clock/Voltage is a Feature that is yet to get tested more by my end and currently is only available on Alchemist Series Cards until i get my B570 which HOPEFULLY arrives early next week. (So that's just a disclaimer, that this Setting isn't available. Core Clock on the other Hand works just fine!)
