Pretty impressive for stock cooler! So I wonder how something like a Morpheus Vega kit cooler with 2 NF-F12's would do on thermals and clocking.

U know what @Hilbert Hagedoorn , Ur overclocking review is one of the most complete and directed-to-average- user reviews i have ever seen.

Pretty impressive for stock cooler! So I wonder how something like a Morpheus Vega kit cooler with 2 NF-F12's would do on thermals and clocking.

From the results I'm finding it looks like the GPU can possibly pull 2.2 Ghz on the core though binning and such will determine where it peaks and what it requires in order to hit that, 2 Ghz seems doable for several of these once the current thresholds and throttles and limits are gone. Primarily that does seem to be heat and thermal related in particular the "hot spot" type sensor which going by Unwinder and his comments in the beta topic for MSI Afterburner the sensor regularly hits 100c so if this is the same as Vega where that could routinely hit 80 - 90c or higher then that's a major factor for this thermal throttling and getting that cooled such as via a good block of metal and cold water is going to really help with maintaining a higher core clock speed. As it seems memory gains are minimal or non-existent possibly only factoring in during some benchmarks now that the bandwidth bottleneck is no longer a factor for this Vega model so gains seem entirely on the core and keeping a maintained and high speed there up from ~1700 Mhz-ish to possibly 2000 Mhz to 2100 Mhz since every GPU is going to be slightly different. Not that I'm that good at this but getting that thermal issue sorted seems to really help and then it's down to bumping the power limit up a tad and then it's up to wherever the GPU peaks at without artifacts and all that or hitting a spike where smaller gains would require even more voltage which same as Vega or possibly even more so if these are Mi50 models that didn't quite make it the results here will be quite varied, some will handle undervolting nicely and others might not have much headroom at all. Still have more to learn and read up on but for overclocking results 2.2 Ghz seems to be close to max thus far. https://www.reddit.com/r/Amd/comments/avafw3/watercool_radeon_vii_2199hz_oc/ EDIT: Ah and I see that initial post got a update too since yesterday I think was when I saw it?

Edit: Working with Power Play Tables to hopefully hit 2300hz. Running into stability issues with it currently even at my 2200hz target much less 2300 target after applying it and I'm stable once I remove it. Hopefully when I figure it out I'll be chugging through 2300mhz maybe even 2400mhz. Though this bykski block has me worried a bit Edit 2: Power play table mod added but running but into to issues when trying to set clock target beyond 2200. Perfectly stable at 2200mhz and with the +%50 power limit getting more consistent 2150mhz+ with less dips. Memory at 1300mhz with out breaking a sweat. Upping the power limit seems to introduce even more stable clocks. Gotta see why I can't run beyond 2200. Going to try rolling back 19.2.2 drivers since I am on 19.2.3

ALL the power, though it will be interesting to see if it can do above 2.2 then. EDIT: Hmm where did the hot-spot throttle for Vega go into effect again, 100 to 105c was it? Maybe it's the same as VII here. (There are some changes to the PCB and probably the GPU core too as a Vega20 beyond just 4x blocks of HBM2 instead of 2x blocks but there are probably many similarities even so though also several differences.)

@Hilbert Hagedoorn What about undervolting the card? Vega shows good results with undervolting. would be interesting to see.

Undervolting is covered at the bottom of the overclocking page.

Ya saw it just now.... pretty disappointing result.

Nice OC, but poor scaling @ 6%.

Thanks 4 the update @Hilbert Hagedoorn! I think it's better to leave the memory at stock and get better OC on core clock since 1TB/s is not a limiting factor, no need to spend more power(=Heat) on the memory OC- what do you think?

It's how things work out in the real world. Undervolting is a lottery same like overclocking. If every semi part from XY company could be undervolted with spectacular results, it would mean that company's engineers don't know the first thing about their own silicone. Is why I /facepalm every time i hear - all you need to do is undervolt yadayada: Look mofo if that was possible, don't you think that it would have already been done in the factory, instead of sandbagging and getting lousy reviews.

I dunno... @ HH seems fine. Hh and hh is weird and hurt my eyes.

i wonder wth is limiting it now, temp seems fine, that core/mem clock jumping around usually means its bumping into power limits due to stupidly high voltages, ive managed to shave off around 150-200 mv on a pair of 570s and a 460 and one of them even oced a bit with the lower voltage but apparently this card just had awful silicon lottery luck or the voltage slider isnt working

Perhaps I missed it being mentioned, but is it safe to assume that the new data published with the "MSI Afterburner update" portion of the review was collected using the original Radeon VII launch driver? Or, was something released later utilized?

My point is @ HH or Hh or hh, capital doesn't matter, is some random person who hasn't been on these forums for over 10 years. It's not hilbert, it's nobody.

Sorry. 🙁 . Was abit busy at that time. Edited

Its the power limit + temp, there are some guys over at overclock.net that are doing 2200-2300 mhz with powerplay table mods + water cooling. there is definitely alot of headroom on 7nm.

+500mhz on a 1800mhz product, is +27 percent, That counts as "alot" in my book, good luck doing that on anything else modern these days.

Indeed, and NV cards oready boost over 1900Mhz w/o OC -so from 1900~2100 is smaller OC headroom then 1750Mhz VII that could OC to over 2200Mhz.
