Missing Bios with ComboAm4v2PI 1.2.0.7 for MSI B450 boards

[BlaezaLite]

In cpu-z benchmark i get a max temp of 72C and i was scoring 510-515 single and 5500multi and now its like 507 single and 5400-5450 multi, temp can be a problem but i dont think the room temps are higher than before , im keeping an undervolt of 0,25 on the cpu.

I'm undervolted to 1.25625, getting 515-520 single and 4410 multi. I've had better results when it was cool in the morning.

I am using an offset for undervolting and yeah i think my single should be 515+ as it was before with some older BIOS, PBO doesnt help at all so i dont have it enabled. The problem can be with the temp or maybe my CPU doesnt like the increased FCLK .
Edit: PPT and EDC are 100% during the benchmark , ill have to tweak them a bit and see if that helps. (maybe they changed some default voltages in this BIOS version and my offset has to be higher or lower)
PPT 88W , EDC 90A

Jinxed me, lmao.

View attachment 254944Jinxed me, lmao.

I think its a temp problem as you said , OC-ing my ram had to increase the vsoc voltage by a bit and i think that is adding more heat , lowering the EDC as low as 60 gives me better results , 5480 multi , 515-6 single.

Wait until Monday and Tuesday... I might give the computer a rest and watch some TV. No benchmark is useful. 35C/37C

I enabled PBO , +50 autoOC , scalar 5x , -0.075 vcore offset , EDC 75 A (rest of the settings you can see them in the picture) and it seems i got my performance back but with my old settings without PBO the performance was worse with this BIOS , temps could be a problem but im pretty sure the stock performance was lower.

I dont like the fact he MSI changed the default bootup option to UEFI and did not leave it on CSM.

How do they expect people with older GPUs to go into the BIOS and change that!

Anyway rant over. Im running 1.2.0.7 on a B450M Mortar Max and its been problem free and performance seems better than 1.2.0.6C

It's a requirement for windows 11
To be honest, apart from some odd cards like the AMD RX 5x0 cards that had missing UEFI for no real reason, any card old enough to not have UEFI support is likely too old to be officially compatible with the platform.

Nvidias 600 GTX and newer have UEFI (10 years old)
AMD's 7750 and above had UEFI (Also 10 years old, both from 2012)

Please be careful when updating MSI similar model motherboard bios.
Because the BIOS chips on the motherboard such as B450 TOMAHAWK are not ordinary, even if you plug them into Eeprom, they can burn out immediately.
An interesting chip with a 1.8v Vcc leg.

MSI Scampers to Launch New AMD 400-series Motherboards with 256Mb BIOS Chips

Our Monday story chronicled how MSI inadvertently erred in giving many of its AMD 400-series chipset motherboards 128 Mbit (16-megabyte) SPI flash ROM chips instead of larger 256 Mbit (32-megabyte) ones, which nearly jeopardized the company's "Zen 2" support deployment, forcing it to greatly...

Here "@Assimilator" has touched on this subject a bit, but no one has even taken it into account.
Finding this chip may pose a problem.

You can update GOP for older cards and its pretty simple.

Just curious, if you don’t have X3D, why would you want 1207?

Edit:

Or 1206 for that matter.

Opened the topic for who has one or wants to buy one + ram oc can be better with a newer bios, some people were complaining about stability with the bios that MSI removed even it was released as stable version.

I downloaded it 2 days ago to get me off that beta bios. Not tried ocing anything since though.

Eww Stock?

I feel like I don't know you anymore

I think its the same as the BETA and they only removed the "BETA" from the description. If anything changed (better OC / RAM OC or something) let me know , im lazy to reconfigure the BIOS at the moment.

Sorry, my ram is OC'd but I've not tried anything else at all. But I just can't be assed at the moment. I have an endless hankering for a 6800XT or 6750XT with a free Ducky keyboard, but the funds are not at that level at the moment.

TPM fix, mostly

Despite breaking my curve optimiser, these new BIOSes run a lot colder for me, so stock gets a performance boost (not that i'm on stock)
