So the old thread is closed, and I didn't want to just start up a new one, but lately I have been receiving AP7 GPU tasks with an ETA greater than 0:00. Lo and behold, they have crunched to completion, so the peak flops bug has been squashed! I just wanted to thank everyone that had helped out with getting that problem resolved!

I wonder.

I have what maybe a Zen 1 motherboard (Biostar bt350-BTC) running with an AMD 2700 (8c/16t) cpu.

I have a Asrock B450 Pro4 (presumably Zen+) MB running with an AMD 2600 (6/12t).

Right now both are running near 3.7GHz.

But the 2600 appeared to be crunching tasks faster than the 2700 when both were running 50% cpu to gpu without the "-obs" on the gpu command line.

So it makes me wonder if my supposition is right. A Zen 1 design MB is significantly slower than a Zen 1+ MB?

I'm using that same Pro4 board for my 2200G. My guess is based on what I paid for it it isn't a great overclocking board. That's fine, I am only OC'ing the memory, so whatever I can get out of it is fine.

Remind me never to come to your house, Tom. I don't know what magic you are doing over there but that isn't the first CPU you've had that is slower than the next processor lower. ;) To answer your wonder, I don't think there is much of a performance difference between the different AM4 motherboards.

Just a typo on my part. 53.3 ohms is the normal recommendation for 2 X 8 GB sticks. I have not actually tried to set the Calculator up for an APU before. I have always had every possible ProcODT valuable in the pull down menu in my BIOS. Your BIOS is probably very simplified compared to mine. Load Line Calibration prevents voltage droop under current loading. Can help stabilize the Vcore and Vsoc voltages under load so the cpu doesn't barf under Seti loading.
Ok, I have heard Load Line Calibration before, thanks Keith & Ian. I did set my SOC pretty low at first (1.05 V, as recommended at one speed), but found I had to bump it up to 1.0875 V. Even though the memory test ran fine at the lower SOC voltage, when I ran Timespy it would not complete. I should have enough to be dangerous, now I just need some time to play with it all.

I'm not sure what LLC(3) is. I'd search for it online, but that acronym is conveniently the same as Limited Liability Company. Do you have a spot you can point me to off the top of your head?

Can I jump up to 60 ohms? The calculator lists 53, 48, and 40 for the recommended and alternate procODTs, if I recall correctly. 53 is definitely the greatest. Oh, and I am pretty sure my Bios lists 53.3, not 53.0. I assumed that is not a big enough deal.

Thanks for the pointers. I haven't combed through the overclocking forms yet, so I have a bit of research to do still.

You could just set the amount of CPU cores and/or CPU time down a significant amount, at least to get some work done if you want.

Would a Corsair H60 have enough cooling capacity compared to the Wraith?
That is the only thing available within 60 miles of me, otherwise I've got to go mail order.
I'm not familiar with AIOs, but I would be concerned with the size of the radiator that you don't have enough water volume to cool the CPU properly. Also double check the mounting. I found a page on Corsair's website that doesn't list it as AM4 compatible, but Newegg does.

Hardware Unboxed did a video about cooling performance of the 3900X. It seems to run around 86 C with a 1 hour Blender burn-in, so it doesn't surprise me that you're having thermal issues. I think an upgraded cooler is definitely in order. That's a bummer. I'm guessing if you just use the 3900X for gaming, which typically is not using the CPU cores to the game's advantage, you're going to be fine. Boinc and Seti, not so much.

If you don't get the three memory training cycles and a final POST beep, the memory settings are bad and will fall back to 2133. It can also lock up the machine requiring a BIOS CMOS reset to get back to square one. Ryzen has always done best with single rank memory sticks in the 2 X 8GB configuration. It also has preferred memory made with Samsung B-dies. That memory is easiest to achieve rated XMP settings of the memory sticks.

Have you tried the Ryzen DDR4 Memory Calculator by 1usmus? https://www.overclock.net/forum/13-amd-general/1640919-new-dram-calculator-ryzena-1-5-1-overclocking-dram-am4-membench-0-7-dram-bench.html
It really does make it a lot easier to achieve decent memory timings on Ryzen. He works with AMD and is privvy to lots of technical information that only developers are given.

The current version is not setup for Zen 2 yet but if you use the Zen+ selection, it will be close. He says a new version able to handle Zen 2 is forthcoming shortly.
I usually check HWinfo before running Testmem to verify the memory clocks are correct. I have had it revert back to the slower speed on occasion.

I am using G. Skill Flare X 3200, 14 CAS. 2 x 8 GB dimms (also plugged into the correct slots) Its single rank and B-die, so it should be optimal for overclocking. Yes, I am using the new calculator and I have been following 1usmus' guide. I was able to get 3266 with little pain, but at 3333 I keep getting a few errors in testmem. To be honest, I probably have not been as meticulous as I need to be, so I feel I need to start over and keep better records of what settings I have in bios.

Also, its a 2200G, so that should be using the Zen 1 settings. I'm not aware of anything else that needs to be considered since it is an APU, although I'm curious if I should be doing something different since the memory is shared for the Vega 8 GPU.

Huh, I don't know that I have noticed that yet, at least every single time. I have seen it turn off and on for 3 cycles occasionally, but perhaps I have not been paying close enough attention. Now I'm thinking the one time I saw that happen when I changed the procODT, perhaps I should not have dismissed it as a "bad" setting.

I've only been able to OC from the default 3200 up to 3266 so far. I played with 3333, but I haven't had enough time to be successful (with no memory errors) yet.

Hope you were able to snag the 2700X that was on sale for $199 at Amazon today or $159 at Newegg.com. Looks like all that stock went quickly. Now only third party sellers have any stock for much greater prices.
That $150 price on Newegg was for the non-X 2700. I was drooling at that one until I remembered I don't have discrete graphics yet.

XMP profile #1 is shown as 3200MHz CL16, profile #2 as 3000MHz CL15. The memory is HyperX Predator 3200Mhz CL16. I couldn't get it to select either XMP profile. I could set the memory speed to pretty much any value it had on the drop-down list but it goes back to 2400MHz when its rebooted. I've raised a bug with ASUS.
When you switch the memory speed, is it booting up right away, or does it have troubles posting? I've started to overclock my memory on my computer. In my limited experience even if you change the XMP profile the ram timings may stay the same from your previous memory speed if you're not careful. I could see the situation where the memory speed is changed but the timings stay the same, you close out of bios, the computer has trouble booting, and reverts back to the old memory settings after trying a few times.

I'm assuming you have checked mounting, thermal paste, etc.

For my ASRock motherboard I had to change a setting in bios for the fans to monitor tctrl, not the CPU or mobo. If you haven't checked, see if the cpu fan is monitoring the correct sensor in bios.

The only issue I have had is with the mobo treating my memory as DDR4-2400 when it’s actually 3200. I’m blaming ASUS for that one and expect they’ll iron out issues with the bios in due course. Mother board is a X570-P running it on optimised defaults apart from fans which are set to turbo.
I assume you switched the XMP profile to 3200 and its still running at 2400?

re: "... and is shaming me into donating again." Ironically this is quite possibly correct: mine were the same except that the hard disk was the extra one, and it was actually indicative of >1 year since my last donation. I strongly doubt this is by design. When I made another donation the hard drive went away.
So you're saying donate, and the problem will go away? Clever girl...

My profile shows that I have three donation icons: a spinning star, a HDD, and a GPU. I have only made a donation for the HDD icon during that fundraiser. The other two icons are not valid for me, which simultaneously makes me look like a liar and is shaming me into donating again.

I thought this was a back burner item that was brought up months ago, but I discovered this week that it was believed to be fixed. So, could this be re-fixed? Thank you.

Test results and summary about what I expected. AMD is back on top for consumer general purpose cpus. Need to see more reviews of Ryzen Gen. 3 on older X470 motherboards.

From the later tests and reviews comparing the same Ryzen 3000 cpus on X570 mobos against X470 mobos with the same memory kits, the X570 boards have a slight advantage in memory speeds over X470 motherboards.

Still, it's great you can just drop the new processor into the same socket on your X470 or X370 motherboard and get better memory speeds than you were able to achieve on the X370 and X470 motherboards.

Proves it wasn't the motherboard or memory sticks that held back the memory speeds on the earlier generations. It was the IMC in the earlier cpus that limited the memory clocks.
There were a few Youtube videos I watched last night about the X570s. One from Hardware Unboxed showed that there was not a huge difference in performance using the same Zen 2 CPU, whether it was in a B350 or an X570 motherboard. However, you need to be careful with overclocking, as the VRM might reach temperatures greater than desired. Additionally, Der Bauer has a video showing power draw on the X570 chipset. His video demonstrated that there is a significant power draw on the chipset even at idle, with no PCIe 4.0 devices connected to the motherboard.

I know the additional power draw of the X570 chipset may be insignificant compared to the draw of a high-end GPU, but to me I don't know that the additional front end cost of the motherboard or the additional power I will consume is worth it. I don't think PCIe 4.0 has any significant benefit to Boinc at this time.

My laptop has... I think 5 WUs left to crunch. I have seen 2 WUs now, that were rated at 5hr and about 20min run time, running in excess of 12 hours. Is there a reason for this happening or have I found something wrong? Most others have run in just over 5 hours.
I have had similar problems on this laptop. I have had MW tasks take several DAYS, even though the CPU is halfway decent. I changed a few things: Reduced stored work to 0.5 + 0.02 days, disabled crunching iGPU tasks (I had turned it on to see what would happen for a few weeks), and I reduced core/thread usage from all 8 down to 6 or 7. I'm not sure if any one in particular was a smoking gun, but my times seem to be more in line now. I'd like to figure out what specifically caused this, but I don't have enough time and interest to pursue it.

For reference, I asked about this question on the boinc forums and on Milkway.

I now have my dinosaur laptop, 13 years old, running SETI. No co-processor, only CPU. We'll see how well it does against my tablet and Pis. :)
Would that happen to be Computer 8747611? If so, I challenge you with MY old laptop, Computer 8513868! Even if your processing power is half of mine, my guess is your RAC will be higher than the Pis

Hi Bill,

Yep, that be the one. It's got a Pentium dual core CPU, 1.73 GHz, 2 GB RAM and Win7 Home Premium 32bit. I believe it has an 80GB HDD.

I got that laptop in 2006 at Best Buy. First time ever buying from them. :)

How old is your laptop? The most I used mine was in 2012 when we had to go to the library to do stuff. That was about a 6 months stretch. Other than that, I hardly used it. Just had it just in case. :)

Have a great day! :)

Siran
It has to be at least 9 years old. My wife had it before we met. I'm sure I can figure out how old it is but I'm too lazy at the moment to figure it out. Its been sitting around collecting dust for several years now so I thought why not let it crunch instead of doing nothing. I installed Ubuntu on it. Hopefully one of these days I'll play around with it more to get familiar with the OS. And if the machine dies out, its not like it was much worse off than when it was sitting on a shelf.

Post:
@Grant Why RTX? Aren't the new 1660s a better deal? For Seti obviously...
(It's been a while since I visited Shaggie's charts, so that may be a dumb question)

Here's the most recent chart, and you'll see why the RTX 2060.
The RTX 1660Ti is about on par with my existing GTX 1070s. I figured if I was going to replace my GTX 750Tis, the replacement should be better than my present best cards. And while the 1660Ti leads on efficiency (and the RTX 2060 isn't a slouch in that regard) the RTX 2060 pumps out quite a bit more work.
However, the RTX 2060 Super has an increased TDP by about 15 watts. I am curious to see what the credit/watt-hour is for the Super compared to the standard 2060 (and 2070). I don’t expect the shift to be huge, but I am not sure if it will move left or right on the chart. If the Super cards do not have a differentiation from the standard cards (as far as what Shaggie can obtain with is code) we may never know what that difference is.
