If you're using ASUS boards
vSOC 1.25V
voltage for mem controller / ram 1.35V-1.36V

Overly high vSOC and vMC will actually be less stable

Rest of timings per this post from Buildzoid:

HUB review of the ASRock mATX B650 board is up:

Short summary: "Actually really good [for the price]"
-Stock settings enforce a 85C limit for CPU which makes a slight difference in MT performance and VRM temps. But VRMs are still ok with this limit removed and performance within 1% of top boards for the most part. VRM adequate for 7950X with stock limits removed.
-Power on to Windows boot time of 16 seconds
-Echoing my experience with ASRock boards... default XMP/EXPO timings suck. So you will give up gaming performance (few %) here unless you manually tune to at least Buildzoid timings. And their BIOS is bugged for the memclk divider currently (at least on X670E board in my sig) so forget going faster than 6000 MT/s.
-Overall, a solid budget board. Once I can buy a 7800X3D my 7700X in my main rig will be going into a mATX build using this board
So after spending literally days trying to get the 6600 to work at 6000, I got my 6000 cl30 expo this morning. I put it in, selected docp I in bios, booted in about 20 seconds, and BAM works perfectly. Worth every penny to me of $138.

I feel obligated to say something about the Buildzoid timings that are so frequently referenced. I can't speak with personal experience with his Zen 4 timings but I do have relevant experience on the Intel side.

Don't use those timings, seriously. They're overly aggressive, I would say it's overly aggressive even for a 'power' user that wants every possible frame. Certain timings he has listed such as tRefi at 50000 are just asking for data corruption. His listed timing for tRas at 30 is insanely tight for literally zero benefit. You will never notice a difference between a default tRas of 96 and his setting of tRas with a value of 30.

The best DDR5 kit you can buy for Ryzen (by far) is this kit, it's basically overclocked with the EXPO settings out of the box. If you want a 64Gb kit, this is the best you can get, as a bonus it will also perform slightly better than the aforementioned 32Gb kit.
You do know the Zen4 memory controller totally different beast compared to Raptor Lake controller ?

For fully optimized/maxed out memory settings for the current AM5 platform i feel obligated to direct you to this leaderboard where the minimum requirement is 10k coverage in Karhu memory stresstest. (as a performance metric you should be looking at Karhu mb/s)


What buildzoid have posted is the minimum timings garbage bin hynix m-die should run without any problems..
If you really want to extract the maximum memory performance from the AMD DDR5 platform, hynix a-die is recommended as it can run tighter timings (m-die caps out at 150ns tRFC)

Were zen 1 ram issues this bad or worse? Thank you to the few who I've now forgotten the names of who recommended ram kits. I'm in the process of setting out some cases and want to go for cheap high air flow cases. I'm open to suggestions. Basic, cheap and light is what I want. I might be asking too much for cheap but a hinged glass panel would be a delight and I can open and close during hot days or if I need to direct more cold air into the systems during hot days.

They just look different but essentially the same thing. DF800 is uglier, in my opinion.
Thank you. I was looking at the DF lineup earlier a few hours before I asked. maybe some stars aligned and that's why you recommended it. I don't think you can beat the price in this economy even if it's 20 bucks more than it should be.

Far worse. You'd be lucky for the memory to boot at DDR4-2400, a lot of common memory flat up refused to work at anything other than JEDEC speeds at launch. There's a reason why people paid a premium for memory with Samsung B-die.

And a premium it was. I just looked back at an order with a G.Skill Flare X 16GB kit (2x8GB) of DDR4-3200 CL14 memory and it was $183.99 in March 2017.

I've spent less than $130 each on my 32GB DDR5 kits so far.

Oh wow. I bought B die but it was cheap for 32 gb kits. I didn't know the story of b die went as far back as 2017. I was interested in ryzen around the time of its release but quickly lost interest when some real life issues took up my time. It wasn't until the zen 3 came out that I had renewed interest but not being able to get what I wanted I opted for an equally expensive Intel build. It keeps my upper half warm on winter days.

It was pretty bad. I splashed out cash for 16GB of b-die (DDR4-3733!) but it was a long time before Zen-specific kits like FlareX came along and made memory easier for AMD users. Plus you had to worry about whether your board was daisy chain or not.

We had no Ryzen Memory Calculator for the longest time, either. It was all hand-tuning.

That explains what Flare X is. I knew Ripjaws was lower than Trident but couldn't figure out what Flare X was for gskill. I've got ballistix ram in my intel atm and it's fine. Very much insert and forget and I imagine it was the same for zen 2 and 3. Most of my ram over the years has been patriot or kingston.

FlareX was specifically touted as the first RAM kit to hit DDR4-3200 CAS/CL14 guaranteed out-of-the-box. Sure you could do that (or better) with nice, expensive kits known to have b-die, but that required extensive hand-tuning and research. FlareX was ready-to-go assuming your board could handle it. Not all of them could.

The EXPO situation is overall much better.

I've run into online posts where enabling expo causes long boot time memory training and turning it off makes training breeze by but brings some instability unless you fiddle around.
Yeah I've heard the same. Memory training was insane on early AM4 though. The boot cycles where my board would shut down, restart, shut down, and then finally work had me freaking out. I would take a 20-30s boot cycle over that mess any day.

I managed to snag two 7800X3D processors online from Amazon and Best Buy respectively and attempted to cancel my Amazon.com order since I could pick it up sooner at BB in store, but they're saying it was prepped for shipment already. So I'll have two 7800X3D chips by next week. Decent problem to have considering it looks to be sold out now.

Now that I'm sober I'd love to say something here but may get into trouble. LOL You can return it no hassle to either company or if you have children you can build something for them or sell it for a high price. I'm surprised Amazon began prepping the order so soon after ordering. It usually takes them half a day minimum before I see any updates to an order on prime. I'm waiting on a 50k sheets of quality copy paper due to arrive in the morning. Cost was $10 less per ream compared to an office products store. I wonder what the catch is but I shall sea in the morning when the delivery truck arrives and backed up to my garage.

In the unlikely chance you decide to get rid of one, I would be very interested....

The is the first time I'm hearing about this too. I only began touching AM4 on the X470 and B450 chipsets, mainly MSI boards. I didn't run into an issue until I tried overclocking Zen+. I was unaware overclocking on Zen was a fruitless ambition until I'd spent several hours resetting the CMOS and then finally giving up and googleing which got me nowhere until I looked the issue on older sites that still had long time posters. Overclocking is still viable on Intel but you're already dealing with a nuclear reactor.

The time figures for AM5 I've seen since the first issue was brought up a few days after launch range from a short amount of cycles to training for up to 20 minutes. Right now for a lot of AM5 systems startup from button press to desktop seems to hover around the 1 minute range. Unacceptable if your sat in front of the computer otherwise it isn't a big deal if you're doing something else like grabbing a drink or something to eat. 1-2 minutes were what I remember hdd's being like.

Oh, you horrible tree killa!
I would have gone for recycled paper but recycled paper doesn't come in at a heavier weight or better gsm that I know of. I shred and use used paper as mulch on non edible plants and trees. The tree species used in most paper production are hybrids that grow at a rapid rate of several meters a year. Don't fall into the green hype thinking it takes forever. Most species and their hybrids grow anywhere from 3-12 meters every year to two years at the top end in the most adverse of conditions.

Still, what are you printing that needs so much paper? You could explore ways to prevent the printing. If you are doing it for personal use, why not just get something like a Kindle and read the stuff on that?
Not for personal use and needs to be on paper. It's not a lot of paper. Only 100 reams. It's good for 2-3 years.

The setup was pretty straightforward. I removed the Intel chipset and network drivers before switching out the board/CPU, and then set up all the AMD drivers. Expo settings worked out of the box and the curve optimizer sets all cores to -30 with a max of 5150mhz. The boot times are noticeably longer but not as bad I feared, it's mainly the initial POST that takes longer. It's my first AMD setup in over 15 years.

I tried out a few games in specific areas that used to slow down to 70-90fps on my old 10700K (e.g. the Arasaka tower jungle area in Cyberpunk, or the Byzantium area in Outer Worlds). Sometimes it's much faster and other times there is no difference. I haven't tried VR sims yet, where the improvement is said to be larger.

On the issue of shared M.2 lanes, I can see a clear reduction in SSD speeds in that slot (with Crystal Disk Mark) even with a gen 3 SSD, to about half of what they should be. I normally prefer to have my sound card in that slot because it leaves more room for the video card fans to intake air, but had to move the card up.

Also, for all the talk of power efficiency, the total idle power is 30-40W higher than my old setup. I'm not that concerned about efficiency but idle is more important than load.
