Looks cool. Though I'm wondering, what makes it limited besides the production number?


This £50 Kolink case is the best airflow case I've ever had. And I've had some expensive Corsair show cases, Aerocool and Coolermaster, too. I've learned through the last 5-10 years that money doesn't equal airflow.

Kolink is awesome for budget ITX. Simple, no nonsense.

Older games is all I have
Really, except for F1 2022 I think the newest/heaviest game I have is HZD.

HZD will be so smooth you will be over the moon

 

[Vayra86]

I prefer leaving it at stock. Or dragging down the power slider to -10% which results in about 3-5% lower performance at MUCH lower heat and noise production.

I know, I'm lazy.

This is not The Way for RDNA3 though.
Undervolt the core to 1025mv, pull your maximum core frequency slider to 2600 mhz, minimum clock 500 mhz. Pull VRAM frequency to 2600mhz. Pull the energy slider to +15%. Frame limit your games to whatever FPS you want to achieve.

Enjoy reduced power at maximum perf and frametime stability. Clock will be pegged at 2600 most of the time, but you'll use far less power because it stops boosting past 2600 which is the territory of diminishing returns. And if a game is too heavy to consistently hit 2600, you'll have the extra energy budget (+15%) to get closer to 2600 when its really needed.

-10% on the energy slider is really not doing much if anything. It won't make the card more efficient, it only curbs clocks a little but card will still boost beyond efficient VF curves.

 

[AusWolf]

Haha That is why you UV first.

Unlike many, I don't care about that 5%. It's undetectable without a benchmark anyway.

Hm, that's interesting. I might try it.

I got a nitro 7800xt - jesus christ this thing is a pain to OC (mainly undervolt). If i remember correctly, the voltages arent the actual voltages but rather offsets for voltages defined somewhere else? Its really painful to nail down a set range.

So far, i have been able to get 2525 at 0.9v - at least its better than stock. It wants 1.09v for 2500 core. Pure Insanity.

Also, im running an FT02 (vertically mounted) and i'm very hotspot limited. As soon as it gets into the 90's, i get worried.

Heck, a tiny OC into the 2600's with 1.05v+ puts me into the 100's. Is the nitro known to have bad hotspot temps?
It seems excessively high. The difference between core and hotspot can be as high as 25-30 degrees! It gets worse as the clocks get higher.

Finally, since im hotspot limited, i cant crank the power either. Ive seen it go above 110 easily. Its not a good feeling.

Did you like OC your CPU back in the day? Did you like OC your GPU back in the day? I will tell you one of the differences with RDNA3 is that AMD left a lot of performance for you (or board vendors) to extract from the card. The one click buttons are super easy and if you take a little time you can turn a 7900XT into a stock 7900XTX. Though no 7900XT can go over 3 GHZ on the clock like all XTX cards can but at 144hz 4K it is butter smooth and unnoticeable.

I think i've come to the same conclusion after 3 days of overclocking and testing my nitro. You can get a rather good setup at 2600 but after that, the voltage requirement really gets outts hand.

Yeah this is exactly what put me off on overclocking RDNA3 at first too. Its counter intuitive.

You're not really saving power with the undervolt on its own, you're just making it unstable. I had lots of crashing similarly at 1025mv ánd 1050mv ánd 1075mv because I didn't set an upper limit. Some frequencies will ask 1.1mv and then poof you're CTD'ing. The card doesn't limit itself like an Nvidia card does to remain stable. That's also why the min. core frequency should be left at 500, card will readily clock to around 2200 mhz in the heaviest of titles... If you set a minimum that is above 2000 you're not going to get stable either with an undervolt, I reckon.

I bet you can still run your card at 1050mv or better.

As for the temp behaviour and hotspots, your experience is like a carbon copy of mine too. But, 110C is still fine. Card will run, boost, not throttle hard, and is stable at that temp. A high delta between hotspot and edge temp means your cooling is working well, but there's just a very high power density in the chip itself. I lost those hotspot temps when I went about my described way of 'overclocking' above here. Now I peak at 85C, the emotional sweetspot for a GPU

 

[Kabouter Plop]

edge hotspot delta is high cos AMD chips aren't that flat hotspot is bulging creating pumpout issues that are worse at higher power limits, there really only few solutions against that, and that is to use either thermal paste that does not pumpout or somekind of pad for gpu core including PTM7950

Im not doing any undervolting power limit at 410 tbp i hit about 60-70c hotspot range at 22-23c watertemp at idle underload it does not go higher then 2c
No change after 3 months almost with ptm7950
PTM7950 also has melting point of 45c so consider this that side of my waterblock is always much colder causing the edge of my core to always remain solid probably creating a barrier with the excess PTM7950 that got squished to the side making it so the hotspot area always has PTM7950 which probably the reason it does not pump out.
my edge is usually around 42c if i record tho it go's up towards 45+ while hotspot temp drops.

I never record with relive or barely cos it does not support HDR while shadowplay supports HDR since 2020 i believe, on otherhand overlays are tonemapped for HDR which is odd that they did not least do the same for relive recording.

I tried to OC my 7900XTX Nitro, but to be honest didn't find much performance difference. Without testing stability I just set the PL to +15, max clock upped to 3050 and voltage set to 1110, I also OCed to memory to 2650, but saw only 1-2 fps difference between this and stock in games I play now. Stock is Nitro stock so PL set to 400W.

You are most probably CPU limited. There are gains as long you can really tame the temps.

I have 7800X3D and 4K screen, so most of the time I'm GPU limited. But for example in a heavy game like Cyberpunk or Alan Wake 2 when I run those settings I don't see much improvement. I can see the clocks changing (but they never reach 3Ghz anyway), if I run it on stock then alt tab to change the settings to the mentioned ones I see like 2 fps max when I alt tab back to the game.
I was running benchmarks before for Cyberpunk to do more proper testing but still only saw 2-3 fps max gain, and I go from 400W to 450W of power consuption.
Temps are not the issue as I see max 90C on hotspot on my Nitro with those OC settings.

 

[Ferrum Master]

reach 3Ghz anyway

I roll past 3.150GHz often. There's something wrong in your system. My clearly reacts to unlocking OC. 10-15%

Power should peak to ~550W the Nitro+. And it loves to peak very often.

If I render something in Blender then yeah it goes to 3GHz, but in demanding games like CP2077 or AW2, it hovers around 2600-2700.
Don't know about peaks, but I get 400W on default PL and 450 on +15 sustained.

At which position do you have the BIOS switch on?

I don't even have positions, I cross flashed my Pulse to Nitro+, pulse has only one SPI Flash IC. Use HWinfo in background and look for consumption. My score is really the right one as others are getting the same peak 550W load using Nitro+ vBIOS. Not sure... but either way, if you game and OC, and as you say you are GPU limited... it should consume the max it is allowed to do.

 

[thesmokingman]

What are the temps like?

The rads are a little undersized but in 22C ambient max temp is around 43C ish average under load. The block seems to work fairly well and the milling on it is great unlike the EK block. I did compare it to the Powercolor but went with the Asrock because it was a bit cheaper, better milled block, and it has the better vrm/power limit.

That's weird. How is your case airflow? My Pulse 7800 XT stays in the high 80s with its hotspot temp even with a +15% power limit.

I liked OCing when you could get +50% out of your CPU with one click in the BIOS. Anything less is unnecessary hassle, imo.

You can get that now too, heck, sometimes you don't even have to click, the CPU will momentarily run at +50% before hitting a thermal limit and either blowing up some VRM on your board or just drops back to baseclock to keep within PL limits No user intervention required at all!

Well, HWinfo reports higher wattage, in the maximum power usage

But still I don't see much gain in FPS when running this compared to stock.

My card hits 460w and even then I almost gave birth to a brick upon seeing that.

That's a very good reason not to OC these days. Your CPU does it for you anyway.

 

[remekra]

Did a benchmark run in CP2077. One is stock settings, OC Bios so PL is 400W. Second one is +15% PL, 1110v, 3100MHz max on core and 2600MHz on memory.
If that result is ok then I dont really see a point in OCing the card.

3 FPS difference. This is why I don't OC.

In my case I find OCing Radeons as highly random and unstable work. Had an MBA and later Gigabyte model of 7900XTX and OCed them, but had a lot of random crashes. Thought that it's the famous bad AMD drivers, as my OC seemed stable, could run 3dmark for hours, heaven the same, superposition also. Games also did not crash all the time, but randomly they would crash.
Changed back to default and didn't had one crash since then. Well except in Forza Motorsport on the rewards screen but that is issue with the game.
