What is your clock speed? -500 caps clk speed at 2900-2950MHz for me. If the game is already lower you will not see a difference.
Testing this in a game where clocks are high. This limits me to around 2860MHz, however the voltage drops along with it, so I think it is essentially the same thing as reducing the power limit in those games. I have tested reducing the power limit as well, and that only seems to make things worse. At least with the AMD software, it seems like I am out of luck. If anyone knows anything that shifts the voltage frequency curve up through whatever means that would be greatly appreciated.
 
Greetings. I just picked up a 9070 Reaper and I am would like to flash to 9070 XT. What the preferred CH341A device mfg?

Also, is the 9000-series supported by the MPT or RBE from Igor's Lab? Thank you.

The BIOS chips run on 1.8V.
The CH341A V1.7 has a built-in voltage switch, any other CH341A is also fine if you get a 1.8V adapter. I would recommend the CH341A V1.7.

You should try liquid metal, mine tops out at 75c with 370w, 63% fan, 15% over the auto max of 47%
I was running liquid metal, switched over to a thermal grizzly pad and overall the temps are higher, but the hotspot delta is lower (I tried redoing the liquid metal 3 times, I think there is a issue with mounting pressure on the Steel Legend)

Yes it similar. Usually if you have a voltage issue, its at the higher end of the curve.

What are the chances they come out with a block for the hellhound xt? I really want to keep the card at 350w but the Hotspots get to ~101.9c at 100% fan and core temps to 63c. Card already has PTM and mem temps are not a issue as they maybe get to 92c. I never watercooled a gpu via a block so I'm out of the loop (ha) when it comes to what they make blocks for, only using cpu aio with adapters for my gtx 680 lol.

alphacool said they were going to make blocks for all popular models of the 9070 XT, I think they have one model available but I can't recall which one it was (Nitro+ maybe).

My steel legend has really high hotspot delta too. That might be due to me never running it stock and immediately dismantling it for my failed universal GPU block attempt.
After repasting and putting it back on air the hot spot is 80+ while core is 50-60.

Thank you @ApolloX30 @barium56

@Roboyto I will be following your write up closely, thank you 🙏 Did you repaste or reuse the existing PTM pad?
Arctic MX-6.
I did notice this since flashing the Reaper BIOS. Originally limited to 242W the delta was never over 20C, and now I've seen 30C+ with +10PL (334W). This is likely a combination of the increased PL and not reapplying a PTM.

Steel Nomad looping at all stock settings flashed 304W it sits ~27C. Using max value it is 30.9C. EDIT:
Had the idea to reduce power limit down to 80% = 243.2W. Delta now ~22C. Using max value it is 19.6C. Still not as good as factory, but much closer.
@MQB888R hot spot delta isn't as tight as the PTM7950 at stock power levels, but it is close. Pushing to 334W with XT BIOS and the gap widens quite a bit; 30C+.
What are the chances they come out with a block for the hellhound xt?
Hellhound confirmed as in the works.

alphacool forum - 9070/XT block

I tried to send them my 9070 Reaper for a free block, but waited too long as they said they already had the PCB layout. So it should be identical to the XT as they don't specifically list the non-XT.

Could you maybe replace the CH341A drivers in your tutorial with the ones I mentioned before?

@MQB888R Add'l info since flashing. Tried updating my other reply and site is acting really weird.

Reusing the PTM pad while not impossible, would be somewhat difficult IMO. You can scrape it off and kind of roll it into a ball, but not sure how well reusing it would work if you didn't apply it mostly uniformly on the die.

Noise output is significantly less tolerable at 334W for me.

The cooler also struggles to maintain "decent" VRAM temps with the increased heat load; in an open air situation. Playing PoE2 for about an hour and I saw VRAM temps crest 100C. I had seen mid-high 90's regularly previously, inside my Fractal Pop Air Mini, just never over the 100C mark. Technically thermal throttle for VRAM is 108C, and when I contacted PowerColor they assured me the mid-high 90's posed no problem for the longevity of the card; so take that as you will.

While it's only a few degrees more...It's just a bit of a mind-**** for me to see any component at 100C and think it is "fine". 😅

I can confirm that if done wisely(you need to put remains on a chip and apply some hairdryer heat to allow it to stick a little), it will work very close to the first appliance. I checked myself on my GB Gaming OC XT. Delta on 363W load during Steel Nomad is 23-25C, exactly the same as the first application, and 7-5C better than stock.
 
@Roboyto looking at the PCB and cooler shots you took, you can see that the plate that cools the VRAM is separate from the cold plate cooling the die - based on this, it does not look like there is any active cooling of the vram, only indirect 😿

What is ###'d up is, they advertise "Copper Base Direct Touch," but they appear to have swapped that out on your card
Technology Electronics

Since I am going to be breaking it down, I will probably rebuild with new pads for the VRM, PTM and putty for the VRAM. I am also tempted to place pads on the backside of the card, above VRAM, for additional passive cooling (*I did the same for my 6700 XT)
