hi there, just require a bit of advice building an AMD system, I've had intel since Athlon 64 days,


Currently I have

Mobo: ROG STRIX X670E-A


Now ram is next, I thought I'd grab this,

www.overclockers.co.uk

Kingston FURY Beast EXPO 32GB (2x16GB) DDR5 PC5-48000C36 6000MHz Dual Channel Kit (KF560C36BBEK2-32)

Order Kingston FURY Beast EXPO 32GB (2x16GB) DDR5 PC5-48000C36 6000MHz Dual Channel Kit (KF560C36BBEK2-32) now online and benefit from fast delivery.

This ram is on the compatibility list for this motherboard, but then a customer review says the following,

"DOES NOT RUN AT 6000MHZ ON AMD; Context: To run the ram at advertised speeds, you have to enable EXPO, otherwise you'll run at 4700mhz, NOT 6000mhz, if you enable EXPO, it'll cause random crashes, issues, and memtest will come back with errors, (As it requires 1.35v, and current AMD bios limitation is 1.3v) So to run the ram in expo, you'll need to run it at 5400mhz, as currently, there is no way for this ram to reach 6000mhz on Ryzen systems. According overclockers support, that is normal, and not sure if it was confusion or what, but it felt like they assumed enabling EXPO = Manual RAM OC. TLDR: ACTUAL SPECS OF THIS RAM IF NOT ENABLING EXPO 4700mhz base, and 5400mhz EXPO low voltage option (As the 6000mhz, no longer works) Performance loss is marginal, only around 3% - 9% so do with this information what you please."

Can someone recommend 32GB RAM that will work with my motherboard 100% with expo enabled?

I thought it was the SOC voltage that was capped @ 1.3 in most boards, not the DRAM voltage.

G.Skill memory is more widely recommended for AMD though, from what I've seen.

Edit: yeah, from what your motherboard BIOS update list

Sorry, not sure I understand, I've never really had to look into this stuff with intel before, what does this mean then, I'm going to struggle running memory on expo/xmp settings? all DDR5 chips say 1.35V but the motherboard is limited to 1.3v is that correct?

the ram at £120 for 6000c36 is quite expensive for non rgb version and C36 timings, but that might just be OCuk prices
if they haven't shipped it, I'd think of holding off, esp as you still have a psu to buy, so can bundle it in the same package

I got the following in the end for £116, fingers crossed it works ok, it says AMD EXPO and seemed specced while for the price,

This is my first AMD build in at least 2 decades, I've always loved the stability that Intel has provided over the years but I don't think anyone even Intel fans can deny that they have faltered in recent years, what pushed me over was the X3D line of CPU's, they were just too impressive for the price to not give them a try out, it's only been a few days but even with the same GPU carried across the system feels a lot snappier and games much smoother.

First time booting the system it just stalled on a RAM error (Yellow light) on the M/B, reseating the RAM remedied that.

Only other niggle was the drivers, I remember having similar back in the day with AMD systems, even during the windows installation process it asked me for LAN drivers, and I also end up with device manager showing a few exclamation marks on unknown devices, it usually takes a while to remedy all of them, then updating the BIOS resulted in a few appearing again and a quick google recommended reinstalling the chipset drivers again and that worked, Intel I find you can just install Windows without any extra drivers and your on your way.

Windows 11 is a little buggy, hopefully that improves over time, that aside I'm happy with the upgrade and fingers crossed it stays stable, I've enabled EXPO in the BIOS so the RAM is running optimally.

It's nice to know that you have better longevity with AMD in terms of future CPU compatibility, with Intel by the time a meaningful CPU upgrade came along you tended to need to upgrade your M/B (and sometimes RAM) as well.

Well that didn't last long :-(

Booted up system today and boot just stalls with yellow light on motherboard, turn system off and it boots up again, but restarted system and yellow light stall again, having a google and people say it could be CPU or motherboard which is going to be very hard to fault find and both parts were S/H, honestly I'm about ready to just go back to my old Intel system and call it a day tbh.
 
I'm going to try and resolve this but it being a very intermittent problem it's going to be difficult, sometimes I cant reboot system 10 times and it's fine, and then I'll reboot and it'll stall with a yellow DRAM light, today I woke the system from sleep for example and it was just a black screen, I hit the reset button and it stalled with the red CPU LIGHT, held power button down, turn back on and everything back to normal, restarted system 5 times and working ok, I even hit reset in windows and it booted back up fine, completely random, I'd much rather it was a completely failed system rather being intermittent, what drives me crazy is in windows it's very stable even running benchmarks.

Things I've done thus far,

Updated to latest BIOS (2904) - problem still occurs.

Installed latest Chipset drivers and M/B drivers - Problem still occurs.

Disabled EXPO (Fault was occurring before EXPO was enabled - Problem still occurs.

-------------------------------------------------------

Currently testing enabling the 'monitoring software workaround' in Tweakers Paradise setting in BIOS.

-------------------------------------------------------

AM5 boot issues seem to be a very common fault when you search around the net, this does remind me of owning AMD back in the day rebooting the system repeatedly watching motherboard debug boot lights again preying it works.

This could take weeks as I have to change one thing at a time and wait for the problem to occur again, I am really hoping this problem and can be solved.

Have you tried disabling fast boot and also disabled memory context restore? Fast boot can cause more problems that it solves and Memory Context Restore caused intermittent crashes on my pc when I first built it and was unfamiliar with the bios and what different things do. Once I disabled it my system has been solid and to be honest boot times are not that much slower with it disabled anyway.

Thanks I'll put that next on my list as I'm trying one thing at a time.
