Reason why i never touched BCLK.. Buildzoid said in a video a while back that it can kill M.2 drives, and they still aint cheap to be honest.
Any device or drive should be fine with BCLK up to 105. And the sad truth is that 5% single core is a huge and unattainable overclock with latest CPUs.

Something strange with that chart to tomshardware, review 3800x. Look at far cry 5 benchmark chart. A 9900k stock all core boost 4.7 ghz delivers 134 fps but with 300 mhz more @5.0 ghz it delivers 154 fps. Thats 20 fps more for like 300 mhz loll.
Possibly stock boost is below 4.7, limited by long term power limit. And the difference between stock and overclocked in that review is also ram. 2666 (cl14?) stock, 3466cl14 overclocked.

Tomshardware had an article up about... 3 weeks before Zen 2's release talking about "not being sure who was making the chipset"...

They tend not to be the most... collected (thoughts wise) site around.

The most annoying thing about PBO is that it doesn't expose the thermal limits, going on what people are saying it seems to be rather conservative when it comes to hitting maximum boost clocks.

IIRC when Steve was doing his 3900X LN2 OC'ing it would only boost by around 200Mhz when it was around 70°C under load and he had to get it down to 20°C to add another 200Mhz on top that, that means it's only boosting to half of what they say it's capable of even if you run sub-ambient. They either need to halve their boost claims or raise the thermal headroom so it actually gets closer to the boost clocks they claim.

Posted this previously in the wrong thread but has anyone tried BCLK OC’ing yet?

Worked well for me on the 2700X.

I'w been on 104bclk for 6 months of constant lioad then changed bios over and had 102bclk after.

Atm with 3900x im on 101.8 bclk. All works fine.

@Mercutio depends what brand NVME drives My Samsung is fine. First thing that looses stability is my titan

Very interesting and also a bit disappointing, interested to see if later bios etc make any difference.

I've a Asrock X470 Taichi / 2700X water cooled and enabling PBO makes a big difference in single core and multi core boosts.
Something like 3999 to 4125 all core, 4200 to 4349 single core.

However you cant change PPT TDC EDC manually on the X470 Taichi bios, but enabling PBO puts these so high as to be not relevant similar to Steves video, i.e 740w, 480a 650a.

So maybe all along i've been of the impression PBO is kicking arse, but maybe its just been the PPT etc raising allowing PB / XFR to do its thing with PBO perhaps not adding a great deal. Maybe theres a bit more room on Ryzen 2000 for Pbo against 3000 with better pb / xfr ?

You tried Changing using Ryzen master ??? Seems to be working on C7H

I might have to try the 104 bclk. 3x nvme drives though... dunno if it's worth the risk

Try 101, then 101.5, etc.

About 103.5 on a 2700X pushes boosts up to 4.5Ghz, which is a nice boost TBH. You’re likely to crash before you do any irretrievable damage to an M2 drive.

Hoping these new chips can do the same. :p

depends for who for me its worth it. I keep only system on my NVME if it dies it dies ill get newer faster better at lest will have reason to upgrade

Same here. OS is all I’ve got on an M2. Software is all on much larger SSD’s.

What increase does 101.8 get you on a 3900X?

Yes , without pbo enabled, locked at 141 /95/140, switching to PBO in Ryzen Master, upping the values, applying, then moving to manual with PBO off doesnt seem to keep the high limits and doesnt boost etc. So on Taichi as far as i can see you can only up those values by having PBO on .. but it might not be PBO doing the boosting .. unless i've misunderstood the GN video.

Have never got my x470 Taichi to BCLK even at 101, have an NVME m2 and 4 SSDs and understood it would probably not be possible ? Maybe worked on older Bios from some vague posts on Reddit.

Surprising, your X470 mobo is much better than my X470 Aorus Ultra Gaming.

I couldn’t even use XMP for my RAM @ 3200 with 8pack B-die, had to dial it all in manually instead. My M2 is also an NVME, SSD’s are all SATA.

Had it at BCLK 103.5 at one point but eventually left at 102.8 24/7 which is as near as dammit 4.5Ghz.

First world 3900X problems....needed a stressful workload to see where my temps ended up as nothing else was pushing them past 45 Degree C. Never considered needing more than 2560x1440 before :p
