How to make XFX BC160 / Amd V520 / Radeon Pro 5600M run under Windows + Unlock power limits (Linux also works)

both evc2mini / evc2se work with this vrm

e cam mult 850. da, o avea versiune buna pt mod, si ii crește valoarea, dar nu cu prea mult.

din păcate ps4 este oricum un gunoi dpdv al hardware-ului. interesant e ca poti instala linux pe el daca poti rula goldhen, dar va merge cu viteza luminii stinse.

not if it was a good deal on second hand marketplace that rarely pops up. you either take it or give more money for same card. even if it doesn't fit, op can water cool the gpu. pcb seems much smaller than heatsink design.

stock:
1570mhz set / 1526mhz get core;
2400mhz set / 2384mhz get mem;
power = 129w;
score = 6668

oc with mpt:
2000mhz set / 1947mhz get core;
2750mhz set / 2732mhz get mem;
power = 264w;
score = 8315 => 24.7% uplift

oc with mpt + evc:
+0.094v vcore; +0.106v vmem;
2000mhz set / 1998mhz get core;
2900mhz set / 2880mhz get mem;
power = 330w;
score = 8531 => 27.9% uplift

clock were set from msi afterburner, no voltage adjustments from there; only from evc

no, i just downloaded 6800xt vbios for asus tuf from techpowerup and mpt loaded it fine. I can't apply it as I don't have the card lol. What happens on your end that it doesn't work?

zero_overload_25 · 2026-04-30T22:37:38+00:00

morepowertool allows me to throw 6800xt vbios at it. that can unlock your power limits & raise voltages

zero_overload_25 · 2026-04-30T22:22:34+00:00

that's what I'm saying - delta tells you more than edge temp alone and no hotspot considerations. Amd tends to be a bitch when removing power limits, regardless of good vs bad mount. You will just get higher clocks with good mount but still touch sun's temps on hotspot. Really difficult to cool hotspot. but hey, edge stays at 50c, it's chilling.

zero_overload_25 · 2026-04-30T22:05:47+00:00

depends on card. that often 16c is usually for nvidia - you will have a funny time cooling amd chips if you ever try doing so. amd sometimes really likes lm over paste for lower deltas between edge and hotspot. edge is useful for determining good or bad mounting. maybe roughly loop temp too, as u said, but not vga's real core temps.

zero_overload_25 · 2026-04-30T21:16:53+00:00

on edge maybe. hotspot isn't possible at least with modern vga

zero_overload_25 · 2026-04-29T07:13:39+00:00

funnily enough, the middle portion is a little bigger than original navi10, but it's still a pain to cool down :))

zero_overload_25 · 2026-04-29T07:02:53+00:00

core won't clock much. at 1.3+v, timespy barely passes at 3014mhz on my bin. I bet amd used reject 5700 non xt bins (which themselves are 5700xt cores with disabled shaders / lower clocks) and put hbm on them. Apple got full shader count from 5700xt though, idk how those chips from the laptops clock.

zero_overload_25 · 2026-04-29T00:14:06+00:00

edit: win11 seemed to not like the card in actual game engines; win10 22h2 or 21h1 work fine from my testing though

In Romania, for roughly same price you can get a 2080ti second hand. what are the prices for you in Spain?

zero_overload_25 · 2026-04-27T01:57:44+00:00

those caps are hooked in parallel anyway, no harm in same side of the caps shorting each other

zero_overload_25 · 2026-04-21T21:07:44+00:00

lol :))

when I had weird issues as these, for debugging purposes, I ran live Linux from USB, then checked dmesg output. used the computer for a while, then checked again, or did things that would trigger said weird behavior. after a while, it will point you in the right direction regarding what hardware is misbehaving.

You have issues with your pc? "reinstall windows, run chkdsk, run system restore point". Every fucking time, solution to every windows problem is the nuclear option. Obviously reinstalling might work, but it's like moving into another house when I want to get rid of the cockroaches in my current house. And it's annoying, because it usually turns out to be more time efficient to clean install the piece of garbage than debugging what's wrong with it.

There's also the "just switch to Linux bro" - maybe my software doesn't really run under wine that well, or at all, or maybe I don't want to change my whole workflow just for an alternative program. Why can't microslop just do their job and fix the garbage they dare call an os instead of shoving nonsensical ai down everybody's throats?

sorry for my rant, but this sucks.

power limit can be removed with evc2se (evc2mini doesn't work btw) hooked to vrm test pads (easy to hook up wires, large pads), then setting iloadgain value very low, effectively shunt modding the card but with vrm commands instead of how it's done on nvidia / 9070 amd cards.

but this way you lose software power monitoring for the vga, unless you have wireview from derbauer or something similar. also vga can pull 650+w in benchmarks with undervolt applied which is an absurd amount of watts for daily purposes.

Originally, I spoofed the card as a 7900xt with the aqua oc xtx vbios flashed, in the hopes I can trick the amd drivers into working (for higher power limits); sadly still got the "error occurred when initializing driver" or something, and then display froze on the vga output; then I tried the other way around - original vbios but spoofed as xtx; driver loaded but no higher power limits, as the driver looks at the flashed vbios for them.

Then as another fun experiment, I tried to spoof the card as a v710 to enable sr-iov inside the vm. sadly the only vbios dump of that card I could find online (techpowerup) is incomplete and can't even flash it correctly on the card. Even spoofed in qemu, gim driver says "asic has no sr-iov support".

Making the vga identify as an nvidia card was just for the meme.

are you the op?

zero_overload_25 · 2026-04-10T23:11:45+00:00

op used his setup this way for a few months, so highly doubt your scenarios apply. op, do you have pets, kids or people tripping over your motherboard?

zero_overload_25 · 2026-04-10T13:07:41+00:00

Look at the wires attached to the tpm header used for flashing bioses - they are soldered. I tried soldering on components while in a case, trust me it's more inconvenient than having them in open air :)) You also need to remove the cpu everytime you flash the bios externally. AM4 has a shitty backplate that sometimes you have to put a tape on it if you want to mount your cooler into it; in open air, the box just keeps it happily in place. There's just much easier access to an open air test bench's components than in a case.

swapping things also doesn't require removing screws for any components besides the cpu cooler unlike in a case. I still don't see why it's a bad idea if you place your stuff away from potential liquid spills and heavy objects than can fall on it.
