Safe max voltage for GPU overclock?
Safe max voltage for GPU overclock?
I know that its an old card and that some of you aren't familiar with it, or simply forgot all about it, but, i want to overclock my MSI 5850 tf2 but don't want to push it too far to (greatly) reduce its life span.
Now the thing with this card is that gpuz shows it runs at 1.088V, but when i unlocked voltage in MSI Afterburner, the slider was sitting at 1.165V, and gpuz was still showing 1.088V.
But anyway, for some reason it wasn't stable with stock clock 725/1000MHz and with default voltage, so i had to push the voltage up to 1.205 just to make it stable at stock clock. Now i want to squeeze a bit more out of it, but im not sure if im already even above the "safe" margin of voltage, and googling about it, i found various claims, from up to 1.3V, 1.25V, all the way down to 1.15 or similar. So if anyone has some insight or an assumption, it would be greatly appreciated

The BIOS of the card usually restricts voltage beyond safe levels. This card is quite old and might already be outdated because it needs higher voltages to run normally. How much voltage and power can MSI Afterburner actually push? I’d probably just set the maximum slider and push it as hard as possible until it fails. You could buy a new one on eBay for around $35, which would be a lot cheaper than spending more time on this. Your financial situation is uncertain, but that’s what I’d consider.
I just increase it until you feel uneasy about the noise or the temperature, I don’t mind the voltage much more than the heat because if you needed, you could run under LN2 with such high voltage that it would be dead in air. You might need a custom fan setup to keep things from getting too hot.
The BIOS of the card usually restricts you from exceeding safe voltage levels. But this card is quite old and likely already outdated because it needs higher voltages to run properly at standard speeds. How much voltage and power can MSI Afterburner actually push? Personally, I’d probably just set it to its maximum and try to force it until it fails. You might find another one on eBay for around $35, which would be a quicker option for a small extra cost. Your financial situation is uncertain, but that’s what I’d consider.

I’m not sure how much higher Msi Afterburner will let you push voltage and power, but personally I’d probably just set it to its maximum and try to force it until it fails. You could find another one on eBay for around $35 or a bit more for a few extra dollars, depending on your budget. I don’t know your financial situation, but that’s what I’d consider.

How much voltage and power can MSI Afterburner actually handle? Personally, I’d probably push it to its limit until it fails. You could find another one on eBay for a fraction of the cost, maybe around $35, for a few extra dollars. I don’t know your financial situation, but that’s what I’d consider.
Afterburner supports up to 1.3V, while the other power setting is disabled and fixed. Still, my budget doesn’t allow me to overpower the GPU just yet.
If you don’t want to risk damaging the card, I’d suggest sticking with stock clocks and whatever voltage keeps it stable. As I mentioned, a card needing more than standard voltage usually indicates the GPU is aging and may not last long.
Dunlop0078 shared their thoughts on the BIOS limitations of the card, noting it often restricts voltage beyond safe levels. They mentioned the card is quite old and might already be outdated due to needing higher voltages for normal operation. They questioned how much voltage and power the Afterburner could handle before the card fails. The person suggested maxing out the settings until it stops working, recommending a cheaper alternative on eBay if needed. They also mentioned that the card's need for more voltage signals aging issues and reduced lifespan.
