- In this video we have a look at the ASUS Dynamic OC Switcher feature of the ASUS ROG Crosshair VIII Extreme motherboard.
Dynamic OC Switcher is ASUS’ very clever way of solving one of AMD’s biggest problems when overclocking: while Precision Boost Overdrive provides the best benchmark performance in single and low-threaded benchmark applications, the best multi-threaded performance is achieved by manually overclocking. So, you have to compromise: best single threaded performance or best multi-threaded performance.
Dynamic OC Switcher gives us the best of both worlds as it allows the system to actively switch between Precision Boost Overdrive and manual OC mode. As I have demonstrated in previous SkatterBencher videos, DOS requires little additional configuration work.
Think about DOS as follows: it is exactly like Precision Boost Overdrive, but the lowest frequency is manually set by us.
Sadly, we cannot simply configure a minimum frequency and have the system switch based on that. Instead, we need to use a proxy metric: a certain current threshold or a certain temperature threshold. There is not one specific method of determining the right threshold, so I’ll show you one example using Cinebench R23.

Good video - I am very surprised that none of the other manufacturers like MSI or Gigabyte have offered something similar, at least in their flagship motherboards.
Solid videos dude, with well thought out analysis. Kudos
Wonderful
Asus champion
good video as always, thank you. do you like the amd platform more nowadays?
You deserve far more subs....I don't get it.
I have a 5950x on a Dark Hero and want to set up the DOS but I have been using the PBO in the AMD page cuz I get better stability and numbers than the PBO under the Tweaker page. Can I mix and match? Having the 2 duplicate areas in BIOS is so confusing! Also you mention one way to get the amps to switch off at but I am not clear on that. It only goes up to 32 threads and the Mhz doesn't seem to drop low. Is there any easier way to find that DOS switch over #.
Are there any CPU/RAM OC performance benefits in your opinion switching from a Dark Hero to the new Extreme mobo?
The Extreme has the new Voltage Suspension feature which I found particularly useful for maximizing my all-core maximum frequency. Other than that, overclocking-wise you're good with the Dark Hero too.
@@SkatterBencher Ok, thanks for the quick reply!
How did you decide on the manual OC frequency for each ccx chiplet?
One is 46.25 and one is 45.5?
Any thoughts on oc'ing on an Asus x570 Proart Creator Wifi mobo? I like the tb4, 10G lan, and the ability to run 2 gpus and pcie 4.0 x8 each, but not sure if it has the ability to do any of the things your covering on your channel with a 5900x. I've been enjoying your content and wanting to try oc'ing a 5900x to speed up particle sims for motion graphics (x-particles and &c4d)
I haven't tried that particular motherboard, so I can't give you a useful opinion.
However, AMD's overclocking experience is very similar across all boards since Precision Boost Overdrive is the main avenue for overclocking.
The BIOS options for Precision Boost Overdrive are provided to the motherboard makers directly by AMD. So the overclocking process is very similar across vendors and boards.
Does gigabyte or another manufacturer offer a similar feature to asus' dynamic OC switcher?
GIGABYTE has Active OC Tuner. I covered it in SkatterBencher #26 ruclips.net/video/bxsDScbQJGA/видео.html. There's also a standalone video on it ruclips.net/video/OAeWVKEYufE/видео.html
