Thank you! First post updated. +Rep

Yeah sorry i was not clear enough. The reviews i have seen have used an older/another bios and there wasn't a setting to change the chipset fan speed. But when i check the 0702 with amibcp i can seen a setting now to change the speed. Would be nice if someone confirm now this option is available.

I'd also like to know if there is a zero fan RPM mode.

I'd also like to know if there is a zero fan RPM mode.

From what I can tell the PCH fan runs at 2500rpm - 2700rpm most of the time. There is no zero fan RPM mode in the current 0702 BIOS. The chipset seems to run about 60 degrees with 25 ambient. The PCH fan noise is not noticeable unless i put my ear about 3 inches away from it.

Hi guys, another with Crosshair VIII Wifi and 3900x. I come from Crosshair VII and 2700X. This week i'll build my new PC.. Reading all post!

On opening day I grabbed a 3900x and ASUS C8H. Glad to be joining you guys.

I read that the MSI X570 Creation has a setting in BIOS to set the fan curve for the chipset fan.

Waiting for my new CH8 and 3700X to arrive; it may take a few weeks unfortunately due to very limited stock here in Spain.


For those of you still waiting or with the new hardware already, just remember to keep HWInfo up to date. Latest beta as of time of writing this is v6.09.3850 with the following changelog:

• Enhanced sensor monitoring on ASUS CROSSHAIR VIII series.
• Added monitoring of AMD X570 chipset temperature.
• Enhanced sensor monitoring on ASUS PRIME X570 and TUF X570 series.
• Enhanced sensor monitoring on ASUS Pro WS X570-ACE.
• Added NVIDIA GeForce RTX 2060 SUPER, 2070 SUPER and 2080 SUPER.
• Added monitoring of Infineon XDPE10281 on GPU (Galax RTX 2080 Ti HOF).

Cheers, guys!

Welcome aboard! I'm looking forward to some build pictures.

Thank you very much for the awesome pictures! It'll be nice to hear your experiences.

What's the deal with Ryzen 9 not officially being supported on Asus X570 boards? That blows my mind.

I mean, it's most likely a typo, but I saw someone post on a reddit trying to get support from Asus on a Ryzen 9, and support was denied due to compatibility.

We're not here for shock and awe or Reddit garbage. Ryzen 9 is supported. Depending on the level of support and which channel the user tried determines the actual support. When you politely ask to be directed to a supervisor or manager, normally they are tech savvy enough to understand what processors the BIOS actually supports. Since these are newly released boards, the website links don't fully list anything correctly yet. You can see that from the direct links in the first post. Some information and links are even missing. They'll be updated, eventually...

That's what I figured. I'm sure the furthest they've gotten was some sort of Level 1 tech who only goes by the manual.

I'm anxiously waiting to get my hands on the VIII Hero. Right now I'm running an i7 4930k + Sabertooth X79. Considering I've never had an issue with my Asus board in the 8 years I've owned it and still going strong, I'd like to stick with Asus. My local Microcenter doesn't have the Crosshair in stock, but they do have the Gigabyte Master. Figure I'd just wait for Crosshair rather than kicking myself later.

I'm also interested in the OptiMem III and looking forward to future reviews on any and all benefits that will give.

Hopefully you'll be able to get your hands on one very soon. Newegg has a short backorder on those. Good luck and welcome!

Just come across a post on Reddit by Robert Hallock speaking about safe voltages and AMD Power Plan for Windows making a comeback exclusively for Ryzen 3000 series. I think it will be useful:

No, the 3900X is not being overvolted. The onboard firmware in the CPU controls that, not the power plan. What the power plans do change, however, is whether or not the CPU downclocks at idle or jumps straight to power-gated sleep (cc6 power state).
The out-of-box plans set a min CPU clock of 10%, so the CPU will downclock before going to sleep. Voltage will follow.
Our plans set a min CPU clock of 90%, and then instruct the core to go straight to sleep if not in use. Windows is unable to probe the behavior of the core when it's sleeping, so voltage will not appear to follow.
I highly recommend watching the real behavior of the core(s) in Ryzen Master. It presents sleep and voltage information that no other tool on the planet can show you.
//EDIT: For example, here's a Ryzen 5 3600 with cores running into the 300MHz range. Voltage is sub-1V. And here's a Ryzen 9 3950X (hue hue hue) with all but 2 cores totally asleep. No other tool would be able to show you this level of detail.
//EDIT #2: Because I have not seen it anywhere, the Ryzen Balanced plans have made a comeback specifically and only for 3rd Gen Ryzen CPUs as of chipset driver 1.07.07. These plans optimize the behavior of CPPC2 to get the 1-2ms clock selection we discussed with the media. Any other Ryzen user doesn't need a plan anymore.
//EDIT #3 (7/10/2019 @ 13:49 UTC): One other point I forget to mention about idle cores (as I know people will be checking on this comment for months to come) is the reporting role our onboard firmware plays in what tools read out. Presently, the behavior of the firmware is to report the voltage the cores are prepared to jump to if the processor exits idle and goes to boost. A boost voltage of 1.4-1.5V is consistent with what we've previously discussed for other Ryzen parts, so that aligns with what y'all are seeing with the idle chip. Behind the scenes, the processor is self-modulating to much lower voltages as you would expect an idle CPU to do. The firmware is not reporting the current voltage of the core until the core is awake and loaded, which is why the voltage appears to go down under load. This further extends the commentary that what you're seeing from Windows and tools is not always what's really going on.

That information is very similar to what was being said around the time of previous Ryzen launches. Not all utilities are created equally. Since Ryzen Master is from AMD, it will report a little bit differently than say HWiNFO. This is my guess. Previous Ryzen users seem to already understand what's been explained in this post, but it's very good for the new users. Thank you for posting it! +Rep
