Vbios 2007 is solid on Asus x670e hero, been running it for a few months, had had one expo failed to run but other than that stable as a rock.

AMD Zen 5 rumours
- Thread starter Grim5
- Start date
And it's confirmed - it is indeed a buggy UEFI. Reported it to MSI. I've been on AGESA 1.1.7.0, zero issues. Jumped to 1.2.0.0 and CCD management broken. One down to 1.1.8.0 and so far zero issues, CCD management is back to normal.

What issues you having ?And it's confirmed - it is indeed a buggy UEFI. Reported it to MSI. I've been on AGESA 1.1.7.0, zero issues. Jumped to 1.2.0.0 and CCD management broken. One down to 1.1.8.0 and so far zero issues, CCD management is back to normal.
New news today: Zen 5 CPUs run around 7c cooler than Zen4 at the same power draw
AMD marketing slides says this is because of improved thermal resistance
Ok.. so an interviewer asked what does this mean, did they change the IHS? Did they change the TIM? Nope, AMD moved the position of the temperature sensor so now the sensor detects different hot spot, AMD says the old sensor was detecting temps that are unrealistic and says the new temps are more accurate
The interviewer then asked if this change was done to actually give users lower temps or if it's used to give the boost algorithm more headroom to run higher clock speeds within the 95c limit they set with Zen4. In other words; will zen5 users see lower temps or will their cpu still just ramp up to 95c? AMD refused to answer this question though

B840 is going to be PCI-E gen 3, so it's worse than A620? 
We're in the pipe....., 555
I was unimpressed by the new board specs, especially 840 :/B840 is going to be PCI-E gen 3, so it's worse than A620?
does AMD think we are that stupid? This need more clarification by AMD.

Honestly I think this is a storm in a teacup. It really makes no difference if they have changed how they measure the temperature so long as its tuned correctly to the new sensor.
I think advertising it as a feature is a bit scummy. But in the end the temperature was always just based on however they chose to set it up.
I remeber when zen 1 launched the temperature probe on the x cpus were set 10° higher than what they were reading so that the boost clocks worked they way they wanted.

Ah man, the motherboard i was thinking of getting if i jump on the 9000 series is in a certain sale today. But having not seen reviews yet and early leaks being all over the place and prices not known i don't think I'm ready to commit yet.
Worth waiting for the newer 800 series boards. These will be superior to the x600 boards.
If you don't care about the new features, prices of x600 boards will crater upon 800 series release. You'll also be able to pick up nearly new ones off MM/other 2nd hand sale websites for very low prices.

Rebadged for maximum launch sales pricing and USB4 added, big whoop.
Faster certified memory speeds (EXPO/XMP) for those that want top performance out of the box with 7200-8000Mhz+ without having to spend hours tinkering with timings and corrupting windows installs

wasnt it only a small bump from 6000mhz to 6400mhz 1:1 on x800 series, if you swap to 1:2 then yes 7000mhz+ looks to be possible but again that comes down to agesia updates and a good cpu. testing will reveal if fast ddr5 can overcome added latency due to the 1:2 ratio.
i'm sticking with x670e, i dont need usb4 and with updates faster ram may indeed work.
For the last few decades, motherboard vendors don't go back and qualify old generations of motherboards for new EXPO/XMP speeds. It's one of the main selling points for chipset refreshes - and earns them lots of profit.
Maybe X670E will be the exception and all the manufactures will work hard to get 8000Mhz+ fully stable with EXPO/XMP, though I highly doubt it.
100% storm in teacup. They have allowed for greater spread of the hotspots to dissipate heat along a larger surface area rather than them being condensed to one location. That seems like a logical solution without needing to change TIM and IHS etc.

A motherboard I was looking at was £207 on Saturday. Today its £354.96 in the "Sale".
All a con
