that's super weird, especially since the LAR page shouldn't be any different on the system than the normal web UI.

 

I know. I haven't been able to reproduce it since either. No changes otherwise between initial problem and no problem, however I did change some voltage and boost settings since it wasn't all the way stable...but that was later.

 

Thought it was weird that FAH got so broken I had to delete the data too, never had that before. Been running folding work for a day without problem, still dialing in some rough settings to cut down on time and crashes with my main desktop it's going into.

Been having my own issues lately too. Went on Vacation mid February and came back to one of my rigs with a Gigabyte Aurous Master X570 was crashing and giving me odd window error screens that led me on a wild goose chase. One of the codes that kept coming up indicated a bad SSD. Tried replacing that but then when I was re-installing windows on the new SSD, it kept crashing... SO it wasn't that.  After a bunch of other odd stuff, I settled on it being the Motherboard (I don't recall why...) So I got a new ASUS X570 and installed that with the existing 5900x and.... same thing . After all that it was the 5900X CPU!  Couldn't justify replacing it with another 5900x so I went with a 5800x and installed it. So far so good.   

 

I do have a spare X570 MoBo now! (Fortunately the new one was paid by points from Amazon, but not the CPU!) 

 

Other than that, my PPD has been down lately with all the storms coming through California. Been shutting machines down for a few days at a time here and there because of power outages and such. I hate WU's getting dumped so I avoid that as mush as possible.

I was sad when EVGA opted-out of GPU manufacturing.  Took a flyer on a PNY 4090 with decent confidence as they have sold quadro professional grade cards for Nvidia for years.  So far so good.  This 4090 is in my Win11 gaming PC and I'll run F@H on it occasionally.  My Ubuntu 20.04 all-purpose server box runs F@H on a 3080 Ti 24/7.  I want to upgrade it at some point to keep pace but I want to do it in an efficient way.

 

I read somewhere that PCIe4 x8 == PCIe3 x16 only clips a 4090 by 2 - 8% in games ... which is great and means that I should replace the i9-10850k + z590 with an 11th gen chip only if I really want to.  This means that upgrading the 3080 Ti alone is likely good enough for now.  But, what gpu to go to?  The 4080, strangely, doesn't seem like it's come down in price yet and I can't justify grabbing another 4090.  I feel like I am stuck waiting for a 4090 Ti or a 4080 Ti to be launched to push down pricing.

I don't know who these guys are, but they are suddenly coming for us hard.

 

Well... actually we know who one of them are Miker07 used to fold on LTT

[Kilrah]

They're having a short sprint, probably won't last

We do appreciate some of you coming over to participate. It was fun!

Yep, working on some as real time as possible production stats systems so we can see other teams sneaking up on us faster

@LAR_Systems I noticed that the timer function on your extension stopped working after my latest update from Chrome. I think it was caused by the new 'Memory Saver' function. I set it to off and I think it is working again.... will be able to confirm in the morning.

That would make sense, they are more less freezing the window / session when you have the tab hidden.

Not much I'm going to be able to do about that unfortunately.

Booo... thats negative thinking, just write an entire new FAHControl

I did, it's in beta and runs in the console on windows and linux... then F@H went and released their new beta version of where the client is going.. .it's not compatible... so it's abandonware.

I didn't think that you could. You might put a note next to the timer function that explains this for future users.

I have a folding rig with 5 GPU's all of which 40 series cards, but I think the 3500x is bottlenecking performance a little.

 

I have to option to upgrade the cpu to a 3700x or a 5500, I believe the 5500 is a little faster per core but it has less of them. I also considered using the 3700x and turning off SMT, this would mean the gpu slots could only use physical cores and not logical cores, so 5 cores for the GPU's and 3 for the OS, with SMT off I might even be able to OC the physical cores a little more or perhaps run them at a lower wattage.

 

What do you guys think?

I honestly doubt you'll see any difference. I ran a 2070a forever on an AMD Athon II x64 at 2.2 GHz in a PCIe2x16 Slot. Moving it to a i9-990K made zero difference. The old rule of thumb used to be 1 thread per GPU running at 2.1GHz or above but newer WUs do seem to need more OS threads to run quickly these days which is strange as all the compute is supposed to be done on the GPU so the CPU would just be needed to shuffle the frames back and forth to the GPU, take care of the Checkpoints and receiving new WUs and sending finished ones.

 

If you think the 3500x is bottlenecking things then just shutdown a few of the GPUs for a day and look at HfM to compare WUs from the same project to see if there is any measurable difference outside of the usual run-to-run variances

[Shlouski]

@Gorgon

 

I have just checked now and the cpu is pinned at 100% with each client using around 20%, so FAH pretty much taking all the cpu resources by itself.

 

Before I added the last 2 cards all the 4080's were regularly hitting 14-15 mill ppd, now I never see them go over 10-11 mil ppd with the identical settings.

Might be a side subject, but how are you powering that?

Corsair HX1500i 1500W 80 Platinum

 

Each card is only pulling around 150w, the issue is having enough pice 8 pin connectors, I think all but one has only one cable going to it with a splitter (good quality) going off the second 8 pin to give me 3 8 pins to each card. I periodically check the cables and connectors, so far no problems and they are always cold to the touch.

Are these 4070ti's?

1x 4070 ti

4x 4080

 

One is off for now to see if there is any significant change in ppd. 

 

I think the 3700x with smt off would perform better the 5500 as it would need to have smt enabled, otherwise it would only have 6 cores.

Let me guess. Windows? It _SHOULDNT_ be using that many resources. I'm going to resurrect my 6-GPU rig in a couple of weeks and have 5 2070supers and a 2070A in it so I'll have some hardware to play with. I'll try Wind 10 and Linux for a shoot-out

Monitor your CPU utilization as well. All threads at 100% under Windows will likely tank things.

Linus just shouted us out on the WAN show! No idea what he said tho

Yeah I'm using windows, I did try make a serious effort to get to grips with linux ubuntu in 2008, but the experience was so bad that I have avoided linux ever since.

A 4080 is 7-8 times faster than the 2070, I imagine they will be somewhat more demanding on the cpu, likely made worst by NVidia's driver overhead on windows.

Yes of course. CPU utilization is still very high, but ppd number are up for sure.

 

I have also be looking at CPU utilization on other machines, and they also have high CPU utilization when using 40 series cards. A 4080 at 50% power limit uses around 10% CPU utilization on my overclocked 3700x 16 core machine, and my 4090 at 50% power limit uses around 10% CPU utilization on my heavily overclocked 5600x 12 core machine. Looking at these numbers I'm not surprised the 3500x with only 6 cores is struggling with 5 40 series cards. 

 

I imagine the 3500x might just be able to do the job under linux, but considering I'm going to have a spare 5500 or 3700x laying around, its going to be easier to drop in a cpu than setting up linux.

Linus talked about having someone on the social team "to engage with the initiatives that have been left alone by us", he brings up the folding team as an example.
