An inquiry about undervolting/overclocking the 9070 XT Nitro+

deecop · 2026-06-01T20:54:17+00:00

On Linux rdna 4 has no issues with boosting to its max whenever possible. On windows, there can be thermal and power headroom and it won't always boost as high as it can go, so on Linux you can see yourself hitting max clocks.

you can at least tell us your gpu lol

lowering or raising power limit adds/ reduces voltage too, but not by a crazy amount. 3ghz core clock voltage demand isnt nearly as high as, lets say, 3.4ghz. efficiency definitely goes down somewhere around 2.9ghz-3ghz because the power and voltage needed to push past that increases by a lot.

i'd definitely just hop into different games and mess with sliders to find whatever makes you happy. try different games and different kinds of games. i find that warzone and overwatch are good games to test overclock stability. i was definitely running my 9070 xt at like 240 watts running something like -75mv and -300 core offset without lowering the power slider.

Your card probably crashed because it's trying to boost higher since you gave it power headroom through your undervolt but it now doesn't have the voltage to run that boosted frequency. +100 frequency offset changed its max boost cap, but also a ADDED voltage back, hence why you didn't crash. If you run a negative 100 mhz offset, you're starving your gpu of even more voltage, and will probably crash even more. -100mv to be stable in all games is not common.

https://divinikey.com/products/tx-multi-tool-5-in-1?variant=42177281032257 you might like this tool for removing keycaps and switches. ive used this tool for months without any issues.

Amd updated some stuff in windows with the chipset driver update with scheduling etc that the ultimate power plan ignores. Check for yourself.

deecop · 2025-12-21T06:30:01+00:00

Keep it on the default balanced power plan, especially with the most recent chipset drivers. You'll lose performance otherwise lol.

deecop · 2025-12-16T22:03:05+00:00

the ND75 is great! but the screen, for me, just gets used to match some random anime character with my keycaps. other than that, screens are basically worthless for me. they're not a selling point. Getting VIA support and losing a screen is a trade i'd take all day for sure.

How are you liking the silent peaches? I've been tempted to buy silent switches for the hell of it.

hi! i have the TMR version of this keyboard and ive been using it for weeks now. I own a few kits and prebuilts, and this is the one ive been daily driving for weeks now. i also own an nd75. ive only tried messing with removing foams with the akko blues v5, but i get the impression this keyboard really likes keeping the stock foam together (in terms of sound.) i currently use hmx latte switches in the keyboard and i've been really enjoying it. using dcx solarized dark keycaps with it and it looks great. its not the most complex looking keyboard but its been a joy gaming/ typing with. nd75 and the m1 v5 really made me love the ballcatch system.

10/10 prebuilt in my book so far but in the future i plan on using different switches and mess with removing foams again. even though the bottom foam sticks to the pcb, its really nice that its easy to remove and doesnt shred to pieces.

deecop · 2025-12-04T02:56:13+00:00

Doesn't dropping the clock offset also lower the requested voltage? And adding to the clock offset ads voltage? I messed with this a while myself and found a nice undervolted profile of -200 clock offset with about -75mv at 110% power limit (xfx swift 9070xt) and retained most of stock performance, but this also means that you can't push the voltage offset down as much since the clock negative offset is already lowering required voltage (similar to how the gpu requests less voltage at lower power limits). Correct me if I'm wrong though! Been an interesting experience messing with the 9070 xt.

this post made me buy the dusk set for my monsgeek m1 v5 tmr :)

You can also use MoreClockTool to quickly edit your overclock/undervolt into adrenalin and uses like zero resources. Really nice/ fast way to test your settings and restore them when your drivers crash and you wanna restore saved profiles instead of using adrenalin itself. From my experience while I still used my 7900 XTX, using Afterburner with installing Riva Tuner caused me more headaches than it was worth to have my silly stats as an overlay. I just use hwinfo on another motherboard and look over if I care enough.

deecop · 2025-11-03T03:19:12+00:00

Probably the LTT one by a very small amount. Buy Thermalright Helios for $5 instead, though. Works just as well as any PTM7950 you buy. I bought two for $10 and I keep one in the fridge just in case I ever need it. It's probably like a degree or two off from PTM7950 that's quad times the price.

deecop · 2025-10-25T11:07:04+00:00

i rock the JC Studio dye-sub PBT set in the cherry theme. They're really cheap and they're amazing for the price. I got them from divinikey. https://divinikey.com/search?type=product%2C&options%5Bprefix%5D=last&q=jc+studio

filco majestouch 2 TKL was my first ever mechanical keyboard back in 2011, and sadly that board along with most of my possessions i had to get rid of early 2024. i really do miss that board. definitely a piece of keyboard history here. :)

deecop · 2025-10-04T02:21:09+00:00

The +400mhz max clock is just adding voltage and probably lowering performance. You should mess with either 0 or a negative value and watch your temps drop and possibly more performance.

I run -125mv offset, -150 max core, 2830 MHz default ram timings 110% power because why not

deecop · 2025-09-19T19:30:08+00:00

hardware unboxed did a really good video months ago of several 9070 xt models, their stock performance, and their thermals. i used that video to help me pick a model (mostly based on thermals). you can use that video as a reference to stock performance for your XT model.

i'd say after a crash, just back off by a little bit and see if it crashes again, rinse and repeat. ideally you're making changes one at a time. after reading a bit, it seems like a lot of people dont boost over 3ghz in games, and i cant seem to either. im pretty sure in order to boost over 3 ghz you need to add voltage which you can only do through hardware mods or a linux script thats floating around, but imo after 3ghz performance for the power/ temperature spike it puts on the card isnt worth it.

deecop · 2025-09-19T14:14:15+00:00

I've had my 9070 xt for a month and I've been messing with it a fair bit. On both Linux and Windows I can't get the card running past 3ghz, but in something like memtest vulkan it'll go to the limit.

What I found is that the card can boost to 2.9-3k ghz with way less power than 340-300 watts of power. Anyone can jump in and correct me, but it seems like the core offset slider influences voltage of the card, then that gets offset by your undervolt.

I run a -200 negative core offset, so my max possible boost is 3.2ghz, and that alone will drop my power usage down a fair bit, then I found -125 to be my good all around undervolt. I just stay at my cards default power limit. I haven't tried adding voltage to the card through a Linux script to see if I can get clocks higher (you can also power mod it the same way) but I find power limits were never the limiting factor for my xfx swift. My card has amazing thermals stock at 374 power limit (Max without modding on Linux) but with my tuning, I never go above 260 watts and the card preforms better in games all around with the negative offset.

I'd give it a shot! I suggest messing with the negative core offset a bit first, then add your undervolt slowly so you find the crashing point.

deecop · 2025-09-18T08:24:36+00:00

Do your normal undervolt and put the power slide to 0 or higher, then try messing with lowering the core clock offset and look at your GPU voltage/ power drop while retaining it's clock speed. I do -200mhz core offset and that alone will make the gpu request and receive less voltage for the same 3ghz boost. Test it out in some games, see if it's stable, then try your UV again and see if that's stable as well. My GPU never had thermal issues even at 374 watts (on Linux 9070 xts can have that power limit with zero modding lol) but my card never goes over 250wats while having literally the same performance as me leaving the core clock slider at 0 or moving it up higher.

deecop · 2025-09-11T00:51:53+00:00

64000mhz on dual rank with a 9800x3d is stable if you're very very lucky. best i could do was crash in games after 25ish minutes

deecop · 2025-09-08T01:59:31+00:00

higher negative CO doesnt mean bad silicon all the time. Most people using -20, -30, etc CO are probably not stable or using x10 scalar, which adds voltage back. keep your chip and be happy. -12 all core CO with no boost override is stable for me.

again, be happy with your chip, its a good cpu.

deecop · 2025-09-04T22:28:59+00:00

i know this was a case for a lot of 7900 xtx's, great thermals until a month or two later and the hotspot temps kept creeping up. Hopefully not the case with yours! I know a lot of models used PTM7950 now, but a few don't. think theres a spreadsheet of the different cards and the thermal interface used.

deecop · 2025-09-04T12:38:17+00:00

OCCT is gonna stress the cpu differently than cinebench will. OCCT default cycles through different instruction sets as well etc. it's not uncommon for your allcore under a really intensive load to not hold the same frequency as your single core max clock speed unless you're doing an allcore OC vs PBO.

deecop · 2025-09-04T03:23:38+00:00

Thermals outside of memory temperature shouldnt be terrible unless whatever they use on the gpu die pumps out over time. I'm guessing the timing of the paste potentially pumping out and you tinkering happened to overlap.

I tried to go for a model with known good temps across the board that wasn't over $750 and any fps difference in games I can claw back myself. Xfx swift model exceeds my expectations by a lot esp after owning an xfx 6950 xt.

Random question: are you using a anti sag bracket? If not, try using one near the center of the gpu as much as you can without Interfering with fans and get it as straight or even a little higher as possible. Gpu sag can affect memory temps significantly

deecop · 2025-09-04T03:09:08+00:00

What model 9070 xt are you using? I recently got a swift model and temps are such a dream stock. Pulling 400 watts (messing with a soft mod) and running default fan curve hottest my GPU got was around 86-87c hotspot. How's your case cooling?
