New ComboPI1.0.0.4b NOT FIXING the boost problem of my 3900x.

I got the 3900x on July 15 and already been a lot of bios updates (MSI X570 Creation). I tried all the bios, even the new beta bios with 1.0.0.4b (7C36v161) is not fixing the boost problem. The voltage control still horrible. My 3900x just won't go over 4.399Ghz. 


Beside enable ram XMP, no other changes in default bios. The cooling system is Deepcool Gamerstorm Castle 360 RGB V2 AIO. Windows fully updated, all drivers fully updated. I using Ryzen Master to change and monitor.


My 3900x with PBO only able to get 509 points max in Cinebench 20 single-core test, the highest single-core clock recorded in Ryzen Master was 4.394 GHz, clock rate normally stays around between 4.300 and 4.350, and voltage around 1.49v (what a joke). In the multi-core C20 test, all core boost was 4.09GHz with PBO 7035 points), 4.05Ghz without PBO (6992 points). The voltage for the multi-core test was between 1.380v-1.395v. 

Compare to older bios with older AGESA, voltage still so high, single-core clock rate still not reach marketing spec 4.6Ghz (not even close). The clock rate may be improved 25mhz to 50mhz in the default setting. The only thing massive improved is faster boot time! 

 

The joke is my 3900x able to do perfectly stable with manually set all core to 4.3Ghz at 1.331v, in the C20 multi-core test achieved max 7560 points (low 7490 points), and single-core 512 points. Also, with 1.33v, my 3900x run much cooler at around 70-71C under maximum load (compare to the default setting at 76C). This setting I'm using since the first week. The awful default voltage control still awful after 4 months. 

 

I'm very disappointed to AMD said they fixed the boost problem, however, 3900x at 4.3GHz still much much faster than my 5 years old intel 5960x. Maybe this is not software or AGESA problems for my 3900x? The best of my 3900x can do is 4.35GHz with 1.375v, but 4.4GHz no hope even with 1.49375v.  (under load will black screen and restart).

Re: New ComboPI1.0.0.4b NOT FIXING the boost problem of my 3900x.

Please use CPU-Z and post the actual AGESA installed on your system.  Using a hex editor, it looks like "AGESA!V9.Combo-AM4 1.0.0.4" to me.  MB Vendors have released BIOSs apparently not containing the proper AGESA.  I suspect you need to lean on MSI.  Enjoy, John.

I don't know, I tried all the bios for my motherboard, from 1.0.0.3a, 1.0.0.3ab, 1.0.0.3abba to current 1.0.0.4 patch B (SMU v46.54). my 3900x just not touch 4.4GHz single-core boost.

healbunny, are you seeing a significant improvement in boot time?  If not, you need to ask MSI what version of BIOS you really have.  I suspect it is not the correct one.  Your RM screenshot shows Manual OC and the clock set to 4300 MHz.  I would expect your clock not to exceed 4300MHz.  Please do a Clear CMOS.  Good luck, John.

Re: New ComboPI1.0.0.4b NOT FIXING the boost problem of my 3900x.

I suggest the OP get the proper released BIOS and do not use beta ones.

Next, do not get greedy. If the CPU will not overclock that far, rather than abuse it further, accept reality. Not everyone wins the silicon lottery.

Video card matters more than CPU for gaming.

Yes, I noticed a significantly improved boot time. RM screenshot is my daily manual set up because the manual 1.33v 4.3GHz is much better than the default awful voltage and lower clock rate.

Re: New ComboPI1.0.0.4b NOT FIXING the boost problem of my 3900x.

I did try the released non-beta BIOS with 1.0.0.4. The current one is the second 1.0.0.4 BIOS that MSI released for my motherboard. 

Next, my point is my 3900x just can not pass 4.4GHz single-core no matter which BIOS under the default setting, PBO enabled, or manually OC. AMD should not advertise 4.6Ghz maximum single-core boost if it is not reachable at all! even single-core 4.4GHz is not reachable for my 3900x. 

I understand the silicon lottery, I do not want to open RM every time when entering the windows to apply the manual setting. I want to use the default setting, but who likes the default high voltage, higher temperature, louder fan, with lower performance.

Re: New ComboPI1.0.0.4b NOT FIXING the boost problem of my 3900x.

I suggest that MSI et al will be releasing more BIOS updates as the situation is far from ideal.

Generally with new platforms it can take quite some time for memory tables to mature in addition to tuning processor tables.

One of the big changes in the BIOS is that X570 uses a 32MB chip while older platforms are stuck with a smaller 16MB chip. That was one of the several reasons to get the MSI X570-A PRO. The advantage of PCIe 4.0 will take more time to leverage.

healbunny, have you leaned on MSI?  I believe the problem is there, not at AMD.  AMD's partners have done a very poor job of getting AGESAs properly distributed!  I also do not see a new RM screenshot showing default settings.  You will never reach Max Boost with the frequency set to 4300MHz.  Enjoy, John.

Re: New ComboPI1.0.0.4b NOT FIXING the boost problem of my 3900x.

healbunny‌ wondering if you ever found a solution? I'm facing the same problem with my 3900X; never boost over 4.385 Ghz, high voltages (1.48V and above), in CPU-Z voltages never dropped under 1.0V even on AMD Balanced Plan, using a X470 MSI motherboard and latest BIOS - AMD ComboPI1.0.0.4 Patch B (SMU v46.54).
