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.
I uploaded a comparison with ZenTimings and AIDA64 between 6400EXPO, 7800XMP, and 7800Tuned on my blog 7800 XMP: skatterbencher.com/wp-content/uploads/2024/02/3900xmp.png 7800 Tune: skatterbencher.com/wp-content/uploads/2024/02/3900tune.png Blog post: skatterbencher.com/2024/02/09/skatterbencher-70-amd-radeon-780m-overclocked-to-3150-mhz/
@@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.

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.
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!
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.
@@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!

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.
@@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.
