I am curious to see how many Seti people are running a Ryzen Zen 2 cpu (aka Ryzen 3000)? I am specifically excluding the 3200g/3400g apu's which are Zen 1+.

Based on conversations I see, I THINK there are at least 4 here.

Please self identify.

No APU's here but I did just upgrade one system to a 3700X. So far I'm happy with the performance just not with the boost, the temps get too high for my taste with only modest performance gains. For now she's happily crunching along on base clocks and we're both happy.

I just replaced a 2700X with a 3900X on my daily driver.

Seeing how many BIOS problems there still are, not going to be bleeding edge and waiting till October. That way I can plan my September vacation somewhat easier as well.

The current BIOS is functional enough to run the computer and the cpu. Is there more performance that hasn't been exposed. Definitely. The BIOS' seems to be following the development of the release path of the first Ryzens. So rapid changes at first, then polishing later in the year.

Unless you are one of the lucky ones that has a motherboard with the small prom, then you get a crippled bios with very limited options. I can turn boost on or off, I can turn pbo on or off, and that's it. Can't set a cpu multiplier or adjust fan curves. Hopefully they will come up with something a little better in the near future.

I’ve got a Ryzen 3600 that replaced a Ryzen 1700. Three more on order.

Are you able to keep the same motherboard? Do you notice big difference for seti?

I don't need PCI Gen. 4 for any reason, so my old ASUS C7H motherboards are quite capable of running the Ryzen 3000 processors. I have noticed a big difference for Seti in switching out my 2700X for a 3900X. First, 50% more cpu cores. Second, much improved math functions. AVX application is 3 minutes faster than the SSE41 application I was previously using. Third, much better memory and core clocks are available from the 3000 cpus on the same old Ryzen + motherboards and memory.

I decided to get a new motherboard at the same time. They’re ASUS X570-P and I am using a Noctua NF-U9S cooler on the Ryzen 3600. It’s this host. You could compare it with one of its predecessors here. The new one hasn’t passed the old one yet but it’s RAC hasn’t settled yet either.

May I ask how you set up the cpu to manage its core clocks on both systems? The 1700 ran the cpu clocks at 3200Mhz. The 3600 is running the cpu clocks at 3950Mhz.

For the Ryzen 1700 it’s set to auto in the bios. Memory is DDR4-2400 (what it’s officially rated for).

For the Ryzen 3600 it was set to auto which defaults to 2400 but I have set it to 3200. Memory is DDR4-3200, again what it’s officially rated for.

Yes I know both could have used faster memory but I didn’t want to pay a fortune for the memory kits so stuck to the official speeds. I could have over clocked the memory but I didn’t think the few percent I would gain was worth the hassle.

Yes, you do get some benefit from faster memory on calculations. But the greatest effect on calculation is to have a higher cpu core clock. I have never liked the Auto settings for Ryzen for a heavy multi-core Seti load. It won't keep all the cores that are crunching at the highest core clocks because of the algorithm focusing on keeping only a single or two core clocks at maximum for gaming purposes. Plus it cranks in ridiculous levels of Vcore that are unnecessary which produces nothing but heat.

I have always set a manual clock multiplier for all-core and therefore keep all the cores at the same clock frequency. I have played with every iteration of XFR, XFR2, PBO and PBO2 and none have been able to keep all the cores consistently boosted at any level higher than what I can achieve just using a manual multiplier.

Does anyone remember how long it took before supply caught up with demand the last time Amd had a major cpu upgrade?

I think it was from 3 - 6 months. Saw a news article that AMD can't keep up with demand for the 3900X. Will try and increase supply.

Just like to ask, what do you do with your old CPU (Mine is AMD 1700x)? Throw it away? I live in South America, so I do not see a secondary marked. If somebody has a good suggestion a 3900x will be on its way, but I do not want to buy a new motherboard (I would switch the ASUS 370x to a 450B) or something else. Otherwise I will wait till September and then donate the Pentium 2 for a 3950x with the corresponding motherboard.

I have a tendency to just build another computer once enough cast aside parts on the shelf accumulate for a complete computer. I have always done that since I built my first computer with a Intel 8088 cpu. I just keep handing the second-hand computers off to family and friends.

That is one of the reasons why I upgrade the motherboards. It’s easier to sell a working machine than just the CPU. Ideal is a complete system but people will take a motherboard if it’s got all the parts.
