Radeon 780M Overclock to 3150 MHz feat. ROG Strix X670E-I | SkatterBencher #70

In today's video, we overclock the AMD Radeon 780M integrated into the Ryzen 7 8700G APU to 3150 MHz with the ASUS ROG X670E-I Gaming motherboard.
I already overclocked the Ryzen 7 8700G CPU cores in SkatterBencher #69. Today, we finally get to do the most exciting part of APU tuning: overclock the integrated graphics. The Radeon 780M was unusually tricky to overclock and is especially sensitive to memory tuning.
I hope to explain all that in this video. Let's get started!

I knew the overclock on the igpu would be epic. Lesssgoooo!

[@gamingoptimized]

That's pretty cool, I always enjoyed these overclocking videos, especially when it's on an APU

[@fracturedlife1393]

That's a lot of info, bloody brilliant. If you like memory tuning these look a laugh

[@miajonekem]

Should have asked Buildzoid to sort the memory timings for you 😁

[@davidzam33]

You are THE MAN! Thank you.

[@Steven-hq3go]

Thanks for the technical explanations

[@jamenbrown6414]

Outstanding video please keep up the good work. I think you're the first to actually focus on a review centered specifically on the igpu getting overclocked. Good to see someone took the initiative to create a video of this effort. Maybe if you get the memory timings stable we can get treated to a follow up video of the igpu overclocked along with the RAM & timings overclocked for maximum performance and highlight a few gaming benchmarks. Thanks!

[@Fin4L6are]

For you to deal with such intricate details of overclocking but not with memory timings is somewhat surprising

[@davidzam33]

Yes, that's why nobody really talks in depth about it... Tuning memory must be where the "gold" is.

[@Speedy.V]

​@@davidzam33I totally agree. The memory issues that he was talking about (artifacts ) must be how these guys achieve high overclocks that are stable. Anyone can push some huge voltage and crazy cooling but if the memory isn't stable neither will the OS or games.

[@yuan.pingchen3056]

Some people only care about being the first and don't care about whether their records are meaningful.

[@yuan.pingchen3056]

@@Speedy.V stable is not in his concern list.

[@Speedy.V]

@@yuan.pingchen3056 right. I get that he's trying to gain as much performance improvement but wouldn't having a stable overclock help in running all of the benchmarks he has?. From my perspective if an overclock is not stable under a benchmark it's not really a true overclock but just a proof of concept. I would prefer to have him focus on stable overclock but I understand that his main focus is on max overall performance overclocking.

[@GadgetGamesAU]

Awesome! I am building a SFF PC with the 8700G and decided to go with an A620 motherboard, happy to see that in theory I can still squeeze performance out of it with RAM timings, even if I can't PBO.

[@MODHIIK]

о ничоси ты делаешь годноту. спасибо

[@chovekb]

Come on, man, what percentage of your viewers DOESN'T enable expo?! Stock performance with 4800 ram LOL of course you would get these numbers mostly by just enabling expo! Next time compare the results with stock 6400 ram (or at least 5800, 6000), please! Other than that good video! And of course the biggest hit on the igpu performance is the memory read, or simply the memory clock!

[@samohraje2433]

Sadly to say, those APUs are kinda scam because if you need to play on that thing ( occasionaly ) you have to have the fastest compatible ram with the lowest CL so the price point is way higher than gtx 1650 which speaking of 1650, that card is way faster than 780m and it comes low profiled as well. But if your build can't take a dedicated GPU, spending almost 200€ for 16GB of DDR5 memory is sadly an option. You can pretty much push this whole chip to the limit where the iGPU closely matches a performance of the gtx 1650 so i'm really impressed but still, better to wait for 880m, that iGPU will be equaly fast as 1060 without any overclocks and with them, faster than 1060 so somewhere between 1060 and 1070.

[@chovekb]

@@samohraje2433 they are sill a good-ish value even at the launch price which we all know will drop after several months, cause that level of gpu performance alone costs at least $100! Also right now the comparisons aren't fair cause reviewers and people are comparing 1 2 years old products with dropped prices to a new product with fresh launch price! So after 6 months probably when the prices drop to 300 and even less for a 8700G the comparisons will be more fair, and still that level of gpu performance, which is also integrated in the CPU and super super compact in comparison to a dGPU, and also pretty efficient, that thing costs at least $100 alone!

[@pranze3484]

Wdym, I got 32G DDR5 7200 C34 for 142€, it's really not bad, 12€ more than 6400 C32

[@Proaz15]

​@@samohraje2433 even the 8600g is on par with GTX 1650, so a oc 8700g igpu should surpass the Nvidia graphics card.

[@eduardo.alves.]

Real G

[@wewillrockyou1986]

The memory profiles with Elpida stuff is a throwback lol

[@Hi-levels]

40 pct fps gain is insane

[@ronjatter]

Very interesting that the memory timings make so much difference as with vega Apus it didn't really matter at all. The clock speed was all that mattered.

[@bogdanursache501]

Hey, nice and educative video! Congrats! Please, please do a similar video for 8600g because it is cheaper (i.e. USD 100 cheaper) and thus to see if this APU is a better buy, especially after OC Thank you!

[@SkatterBencher]

Thanks for the kind words and suggestion! Yes, I'm definitely looking into trying other APUs in the near future. But first I'll take some time off to celebrate Lunar New Year :)

[@adeliavalente7552]

If I need a custom WC rather spend my money on Dgpu... I know this is only for science, good job!

[@methanoid]

I love this channel ever since you did a crap GT710 overclock.I like the new videos but would also love to see some old school S771/775 Xeon OCs.Maybe also BSEL mod to get the 400 FSB straps etc.... I find older hardware so much more fun. I BIOS mod GPUs and want to OC the snot out of an old Xeon :-) Come on Skatterbencher, make that video 🙂

dam almost 70% gg

[@max1024]

Very useful thx for your work)) I see you chose 512 MB of memory for the APU? or is GPU-Z issue? What is the maximum size in Gb that can be assigned to the GPU? Are you planning to post the results of 3D tests on HWbot?

[@SkatterBencher]

Thanks for the kind words. You can switch to "Gaming Mode" in the Adrenaline driver which changes the dedicated memory from 512MB to 4GB. That's what I used for all game benchmarks. The rest of the system memory is still shared, so accessible for the IGPU if necessary. I could enable up to 16GB in the BIOS, but I had to disable memory integrity. Not planning to upload the results ... I think there will be plenty of other and better results on there soon :)

[@yissnakklives8866]

Mini pcs should look to this and add these functions to bios

[@Bambadabum]

Great work, thx.

[@meh78336]

All I did was set my GPU speed to 3220 in the tweaking settings in the bios on my ASUS ROG strix B650E-I Gaming WIFI. I Tweaked the RAM and CPU a fair bit to get some decent 3D Mark scores, got Legendary on a fair few, at least for a while, but never did anything other than just type in 3220 on the GPU side of things and it just worked, got it to 3300, but it was a little flaky so 3220 is plenty good enough for now. On the downside with the other stuff, I had it fail to boot on me so often that I setup a bios reset switch next to my keyboard as doing it in the case every 5 minutes was getting to be a pain with how lacking the out of the box DDR5 ram settings are.

[@JJFX-]

Great work! Could you please try to include a shot of most the memory timings in these videos, at least when it's relevant? From what I can see, the tRAS and tRC values in that first 8000 profile were likely way too aggressive. I'm not sure why Asus isn't setting tRC to at least tRP + tRAS for stability but seeing the other timings would be helpful. Tuning memory has become the final frontier of practical overclocking IMO. As you said, you usually can't get much more out of the frequency side these days but default timings can be absurdly loose to the point where EXPO/XMP on some kits is simply terrible. Plus Hynix DDR5 is so consistent that pretty much every slower kit using it has a lot frequency headroom.

[@SkatterBencher]

[@JJFX-]

@@SkatterBencher Very much appreciated.

[@JJFX-]

@@SkatterBencher Bandwidth is impressive but Asus is pushing it with those timings. At 8000 I don't think anyone could run it at 1.45V. Even up to 1.6V on a good board, those secondaries are aggressive for many. For 7800, I'd try 34-46-40-44-84, tRFC 468. If needed, tRRDS 8 with tFAW 32 (16 rarely helpful) and possibly tWRTL 18. Rest should be fine and likely faster even with all of those. If you're extremely unlucky tRP may not be happy but even 38 would be doable for many. You can likely run tRTP 12 and tWRRD 2 if you want.

[@branchprediction9923]

Remarkable gains wow, what do u think about delidding it? Should help with the gpu temp.

[@SkatterBencher]

I'll leave the delidding to more experienced overclockers :) it should definitely help since the limiting factor for thermal throttle is hotspot temperature, not power usage.

[@tomkocur]

Do you have PBO enabled? You could be hitting PPT limit.

[@benjy288]

@@tomkocur Yes PBO is enabled, things have changed a but since my comment, I did notice a difference with faster ram speeds, not a big difference, but I've had issues getting the ram stable, I would encounter a green screen of death after about 30 minutes of gaming, I think the problem was with expo enabled it raised the vddio voltage to 1.45v, I've manually set it to 1.25v at 6000 and things have been fine, the thing is if I want to go to 6400 then I'll probably need to increase the vddio voltage, it might be fine at 1.25v, but I don't know if I can be bothered experimenting again, its annoying playing a game only to have a crash and lose all your progress.

[@RMabudabi]

5700x3d?

[@Fakeman]

I wonder how much further a delid could get you

[@SkatterBencher]

While the chip was hitting TjMax in the worst-case stress test, I don't think better cooling would give much better results. 1) The voltage is limited to 1.25V on ambient cooling and we're already at 1.20V 2) The operating temperature is much lower in Speedway so I could try 1.25V and the maximum frequency is only 3300 MHz. So, overall, I suspect even with a delid and change in thermal paste, the frequency wouldn't be much more than 3300 MHz on ambient cooling mainly due to the voltage limit.

[@Fakeman]

@@SkatterBencher yeah, i dont think RDNA 3 desktop cards go much further than 3.3ghz either. but maybe you could get slightly higher CPU clocks and lower power consumption. Shame it isnt soldered at that price point though.
