7900xt let's see what it can do!

[_larry]

Just built a new system and acquired a 7900xt from a friend who repasted it very well.
At stock clocks and voltage it never gets above 76C while benchmarking or gaming. That temp is the hotspot and memory. (Usually are almost 1:1 in temp for some reason.)

Since it runs so cool, I want to crank it up and see what I can max it out at. What's the protocol these days? Driver overclock? Afterburner?

Been about a decade that I've been excited to OC a card.

Your best bet is to use Adrenalin's built in card control, no need for a third-party program.

I would actually for an undervolt/overclock setup? Max out the power limit, crank the fan curve because that'll bring about more heat. Lower the core voltage curve (re-testing each increment in 3DMark Time Spy non-Extreme) until you get crashes, then bump it back up a notch. Repeat the testing process for the maximum frequency, raising it until you get crashes or diminishing returns.

For VRAM frequency I haven't had much luck on my RDNA3 card, it really won't go any further than 2500Mhz, but YMMV. Leave that for last. You can try enabling tighter timings too but it's usually only a couple of fps difference.

If you undervolt it and not going past 2700-2900MHz, you probably won't have a problem for a long time.
If you overclock it to max for 24/7 (like me), the hotspot paste will bake and you'll need to re-paste it.

The card is enough fast, enjoy it.

@_larry What did your friend re-paste the card with? Regular paste or PTM7950? If it's PTM7950 that should last a lot longer than regular paste.

If you undervolt make sure you limit the frequency to 3000Mhz, it reduces crashes.

Reduce voltage to increase power headroom and increase the core frequency. You'll need to test to see how good your chip is / how high can go stable. Increase power limit to max too.

For memory they'll be a sweet spot and fast timing. Should be the same for all memory of that type, you can Google it.

Interested to see benchmarks stock and OC. Prices of 7900xt are falling fast.

Undervolt has been more fruitful lately than overclock. Unfortunately, I'm not good with this stuff, so I'll let others help you out.

But then, please, don't ever use Furmark. It's a power virus type of load that can kill your card in worst cases. Unigine Superposition or 3DMark Time Spy (ultra) would be a much better choice. Or any GPU-heavy game.

AMD Software actually offers way more than MSI Afterburner and it is a real way to extend the life of your card enjoyment.

 

[FreedomEclipse]

Question is.... What did he repaste it with? MX-4 will only last a few months before pumping out.

If you want to see how hard your card can boost, GravityMark with the Vulkan renderer and 2mil+ asteroids at your native resolution will do it too. You'll pretty much always hit your maximum boost and stay there for the duration of the test.

You can try: Middle-earth: Shadow of Mordor

Yes! That's exactly what he used, PTM7950.

What you use to read VRAM temp?
Use HWiNFO64 sensors mode if not already.

That's really cool. I expected to see 65-70℃ for 2K VR when I picked up a Hellhound but it just wasn't meant to be.
Glad to see people are able to at least get this stuff working where I didn't. Are you just doing desktop with it?
It feels like all of these cards since the early Polaris era have been stock overvolted all tf and back.
I ended up going with the 9070 XT but I'm still waiting on stuff to do a complete overview video and stuff.
I get the feeling that once again undervolting is going to be the first order if not the main bread and butter for it.

If you cap max clock and you don’t let it burst too high you can probably cut a lot of voltage.
My XTX with 2850-2900MHz max clock can sustain -90~100mV (from 1150mV to 1050~1060mV with increased performance from stock and same TBP 380-390W. If I leave max clock on auto it will hit 3200 occasionally and under UV it will eventually crash.

You have to find the balance between voltage, max speed for the best performance on the given TBP.

I have no doubt that 9070s are about the same.
