Anyone have recent experience with Asrock boards? Decent bios support? General stability?

I'm considering an Asrock B650 Pro RS. Lots of features for the money but I don't mind paying a bit more if Asus or MSI provide better software and/or less bugs.
I just bought a Gigabyte board (Aorus Elite AX) for a new system for my daughter. My first time with a Gigabyte board, always had MSI and ASUS boards previously, but like you found it seems like you get a few more features for the same or less money. I went with the Gigabyte over the Asrock you mentioned as it has WiFi (might use Bluetooth occasionally), more of the rear USB ports are USB3 instead of USB2 and all of the M.2 slots have covers for heatsink functionality. But I've heard the ASRock boards are pretty good as well.

@Elfear
The ASRock X670E board I have was missing standard features some other boards had (like S3 sleep support) and still is missing acceptable BIOS post times.

So pretty low tier in my opinion.

I finally gotten to my new toys and it‘s been a smooth sailing to my surprise. i haven’t experienced that 5 minute boot thing and both sets of my DDR5 sticks had no problem booting to their EXPO/XMP specs. One set is Samsung chip based and the other is Hynix stuff, and both booted at DDR5-6400. I got adventurous and booted with all 4 sticks for 64GB and they have yet to complain. That setup defaults to DDR-3000, though. I managed to clock it to DDR5-6000 1:1 with Infinity Fab
ric. Havent fiddled with timings and currently they’re at CL50.

That is an XMP And it works. But it halves the memory controller speed. I manually tweaked it around with several reboots To make it work at 3200 MHz MC

its this


and this


Both kits can do DDR5-6400 with 3200 MHz MC. I’m on my phone right now I will post screenshots later. Overall my memory compatibility/stability concern was overblown.

edit: actually I can’t say anything about stability yet. All I have done so far is booting and running superpi 1m. XD

BTW, from personal experience, my EMP kits had all sorts of problems. the EXPO kits work perfectly. Also, others may go above 6000 at 1:1 but good luck. All I can do is 6000 cl30 at 1:1. I have 3 systems that run that. All 7950x that memory and 3090TI FTW3 cards.

This 64GB setup of Samsung+Hynix chips is stable for Prime95 LageFFT 30 mins, running at DDR5-6000/CL50. (I stopped it). I am only going to keep one set though. (Edit: Just realized the uncore frequency is hidden. I'll take a new shot)

Which kit would you recommend for a 7600X build?

All 32GB kits, ~$150

6000, 36-36-36-96, 1.35V EXPO, GSkill Flare
5600, 36-36-36-89, 1.20V XMP, GSkill Ripjaws
5600, 36-36-36-76, 1.25V XMP, Corsair Vengeance
5600, 32-36-36-76, 1.20V, XMP, T-Force Vulcan

I had ordered a 5600, 36-36-36-76, 1.20V, T-Force Vulcan kit at $130, but it's on backorder so I'm looking for a potential replacement if that doesn't become available.

ComboAM5PI 1.0.0.4 is out for some ASUS mobos (beta tho)

Any Guinea pigs? 😋
I flashed it on my MSI Carbon WiFi X670E


I ran GB again to see if there are any clock regressions or something, seems OK
Got this result at stock.




Quite frustrating, no change logs. Nothing.
I noticed some warnings in the Linux boot up logs disappeared. But I forgot what they were.

T-Force is Hynix and the rest of them are Samsung. Honestly I do think any one of them will do fine since Zen 4's memory controller seems limited to DDR5-6400. Though Hynix chips are generally regarded higher than Samsung ones, iirc. (for DDR5)

I'll add another to the list. $30 extra for RGB. Hynix chips


One more, $30 less for no heat spreader. Pretty sure these are Hynix as well. Known to hit DDR5-6000. You are buying single sticks with these, though.

This. You don't want the headache of a non-EXPO kit.
Thanks. I ended up getting the EXPO kit.

This kit is for a new PC for my daughter and surprisingly, she doesn't want RGB. Saves me a few bucks at least! I originally bought the T-Force kit because it was Hynix chips and I was confident I could get good results with them. I don't plan to tinker with it since it is my daughter's PC. I'm hoping to just set it to EXPO and let her enjoy it.

I am testing those sticks right now and I like them so far. You should be able to tighten the profile somewhat, at least voltages. OEMs overvolt everything to cover their behind. Ran a quick Prime95 @DDR5-6000/32-34-34-36-105-1T/1.36V and it's stable for 30 mins until I stopped.

FYI, ASUS may be in trouble. Would advise keeping an eye on the news over the next few weeks. Rumor is > one person let go, forums shut down, etc. Possible widespread layoffs and shutdowns. Hope that members of the press are looking into it.

I bought G.SKILL DDR5 7600 32GB DDR5. Totally overkill for Zen 4. No EXPO setting to select. Getting better performance than any EXPO kit available. It takes time and knowledge to tweak every setting to get there. 6200 30-38-38 with just about every secondary and tertiary timing manually tweaked.

Passes my strenuous rounds of stability testing.

Infinity Fabric still improves things. But a cliff after 2200 MHz, and at 2200 MHz it seems like random clock stretching occurs.

Prime95 AVX for 2 hours. Effective frequency 5393 MHz for the duration. Seems a bit too good to be true?
