i've specified Cancer, If i'm missing those unspecified WU's i guess that could be the cause indeed. 

I've been taking a look at it a little deeper by diving into my HfM data and it turns out the current crop of poorly yielding WUs are all ones with Small (<100,000) Atom sizes and most of these are Categorized as "Unspecified." It just turns out that a few Projects have launched that need these smaller Models.

I'm just going to leave things stock (Preference = "Any") as it's work worth doing but setting a Preference for Alzheimer's or Cancer would likely yield better on Current Mid to High-Tier GPUs (i.e. >=4070) as most of these WUs have larger Atom sizes.

Still seeing 40+, i dont think this is a couple unicorns at this point?

Have you set your cause to Alzheimer's or something else? I'm still seeing lower aggregate PPD these days from about 125-127Mppd down to 118-123MPPD but I'm currently just running "Any" for my Cause preference. There seem to be a glut of poorly yielding p12296-7 & p14951 "Unspecified" projects currently.

did new WUs drop or something?

i'm seeing consistent 40+M PPD these days, but that used to be 35 or something. 

 

for the record: i'm not complaining!

Nope, not seeing a 14% increase in Production - if anything I'm seeing around a 2.5% decrease over the last week. I'm guessing you picked up a few "Unicorn" WUs

Is there a place where you can find how long you've been folding for?  I know roughly when I started for the LTT forum but I folded sporadically before here and would be curious to see how long it's been.

A belated Welcome to Team LTT then!

For future reference the easiest way is to just click on your Folding Legend Badge here which is linked to your EoC Stats page

Perhaps you had to change your username in the past or get a new PassKey which, I believe, would give you a different ID on the EoC Stats page.

Here is your Stats Page at F@H which shows the other Teams you've folded on using your current username but, unfortunately, does not show the start date.

I believe Jason@EoC also prunes the members from Teams if they've been inactive for a while to keep things a bit more manageable.

Hello. I have a few questions. How to check the system for stability and editing errors. I'm using Poroxmox which doesn't have a GUI.

My videocard 1070ti.

I assUme you are referring to Linux?

Running Folding at Home or any other intensive GPU Load will test the stability of the system. For CPU testing I usually use

mprime -t

which is the *nix variant of a Prime 95 Samll FFT Torture Test.

Editing Errors???

Woo Hoo - Top 50!

i'm getting a lot of these:


but i can reach that collection server just fine. Any guesses as to what is going on here?

F@H is never smooth sailing is it?

The server may be reachable but it may be out of disk space or the collection process has hung - typical long weekend stuff - likely have to wait until Tuesday for it to be fixed - check the server status

Congratulations @Shlouski Top 100!

If anything, i think i learned my lesson using loop cleaning fluids. I'm still waiting on delivery of the second 4070Ti waterblock which is why only 2 GPUs are in the picture now.

RIP.

Wow - That is an expensive lesson. Glad your back up and running.

Mind we're talking about an Quadro RTX 6000

Then it likely you either have your numbers backwards or you are comparing Apples to Oranges (i.e. NOT the same Work Units). It is unlikely a Quadro RTX 6000 with 4608 Turing CUDA Cores is double the performance of a RTX 3080 with 8704 Ampere Cores. The LAR Database has it at 3.5 versus 4.8MPPD for the 3080 and 16.31 versus 29.77 TFLOPS (FP32).

Without knowing which Projects (Work Units) were running on each card when you observed this it's difficult to say what the cause might be but it is likely that you observed the 3080 running a poorly performing Work Unit while the RTX 6000 was running a WU that performed adequately or above average.

If you want to do a meaningful comparison then you'd have to use a tool like Harlam's Folding Monitor (HfM.net) to monitor the GPUs for a several days then compare the performance of the two cards running the same Projects and discounting projects with small (<50,000) Atom Sizes.

For example, one of my 3080s, running between January 1st and the end of February, when it was decommissioned and replaced with a 4070 Ti Super, had PPDs ranging from 4.3 (p12446) and 7.7MPPD (p12264) Clock-Limited to 1440MHz so a 3080 running at Stock should be 15-20% more performant.

My wife has a bunch of rare vhs and cassettes she wants digitising as they getting old. What hardware is best? 

 

From my searches they all seem variations on a theme and are basicly the same but software compatability seems a problem. I don't want to buy something and then regret it because a different device has better video recording.

 

What would people recommend?

Honestly, as others have said if you don't have a 4-head VCR with S-Video output then you'll likely spend less money using a Service to digitize the content.

Old VHS tapes can be tricky as depending on what they were recorded on there can be tracking issues (picture losing Sync and rolling or jittering up and down a bit). The video information is stored on tape as a Luminance signal and a Color (Chroma) signals. The best quality transfer will be using a S-Video rather than Composite (Yellow RCA Connector).

Video Equipment is loosely divided into Consumer, Industrial and Broadcast equipment in increasing order of Quality and exponential increases in price. Good transfer houses typically use Industrial VHS VCR with Time Base Correctors.

If you have a decent VCR and want to do the transfers yourself I'd recommend looking for a Capture Device that has a S-Video input and includes software that can save in MPG or MKV formats to save time not having to transcode from intermediate formats such as DVI. These shouldn't be that expensive these days. I can't make any specific recommendations as I transferred all my VHS footage years ago using a JVC D-VHS machine and a Firewire DVI Capture box.

Hint. Before transferring any Cassette you might want to Fast-Forward then Rewind the Cassette first to un-pack the tape.

Also many Public Library have Digitization Stations that have VHS to DVD Decks.

See the BOINC Projects Summary.

There's Fight AIDS at Home on World Community Grid but a lot of these projects are intermittent.

Was just wondering, with HIV/AIDS also being one of the biggest diseases worldwide, why it’s not included in the Folding@Home disease list?
 

Is this cause the Folding@Home data isn’t relevant for/effective against STD’s, or is the reason something else?

Folding at Home has been used for Research into AIDS/HIV in the past. It's really up to the areas the Researchers are currently interested in.

The system specs are:

Ryzen 9 5950X

Zotac RTX 3080 Trinity OC LHR

Stock Nvidia Quadro RTX 6000 (see picture)

BeQuiet! Dark Power 13 1000 Watts

 

The Quadro:

There where no modifications done to it.

An A6000 (Ada) should Yield about 12.9MPPD on average versus 4.8MPPD for a 3080. Not too surprising given the 10,752 versus the 8,704 Shader Cores, the Quick Return Bonus (QRB) and having similar Base Clocks and being of the same generation.

As for VRAM, Folding at Home only uses 1-2GB of VRAM when running and most cards see little to no decrease in performance running in PCIe slots at x8 versus x16. Currently F@H only leverages the Shader Cores so Tensor and RT Cores have no impact.

Typically the FP32 performance of a card within the same generation (or at least since NVIDIA changed their definition of this in Turing) will sort of (due to the QRB) directly translate to the performance difference. Better FP64 performance will make a lesser impact in some work units (WUs) but both AMD and NVIDIA have "nerfed" their FP64 performance in recent generations.

I thought the Aorus x570 Master had lost half of it's SATA Ports as the RAID 10 Array failed. Turns out that 2 drives in the RAID 10 had failed silently with Storage Spaces NOT throwing any Errors. Oh Joy. Thank Goodness for Backups!

Picked up:

• Asus ProArt x670e Wifi
• Ryzen 9 7950x
• Corsair SF750W Titanium PS
• MSI Ventus 2x RTX 4070 Ti Super (Folding)
• 4 x Kingston Fury 32GB DDR5-5600 (Running at JEDEC 3600 until I can get the RAM Tuned)
• 2 x 8TB Seagate IronWolf NAS Drives
• 2 x 140mm BeQuiet! Silent Wings Pro 4 PWM (Front Intake)
• 1 x 120mm BeQuiet! Silent Wings Pro 4 PWM (Rear Exhaust)
• 2 x 120mm BeQuiet! Silent Wings HS PWM (Bottom Intake)

Reused:

• Lin-Li O11 Air Mini
• 2 x Samsung 980 Pro 512GB PCIe3 NVMe (OS)
• EVGA 240mm CLC
• FirePro W4100 (Display Out)

Installed FANControl to manage Cooling. Connected EVGA 120mm AIO Fans to CPU Fan Header and AIO to Pump Header in DC Mode.

The Gigabyte x570 Master, 5950x and 128GB DDR4-3200 and 650W Corsair PS will be spares for my Folding Rigs

here's a cc_config from Linux but it should work under windows as well:

cd /etc/boinc-client/
cat cc_config.xml
    <!--
    This is a minimal configuration file cc_config.xml of the BOINC core client.
    For a complete list of all available options and logging flags and their
    meaning see: https://boinc.berkeley.edu/wiki/client_configuration
    -->
    <cc_config>
      <options>
        <use_all_gpus>1</use_all_gpus>
        <exclude_gpu>
          <url>www.worldcommunitygrid.org</url>
          <device_num>0</device_num>
          <type>NVIDIA</type>
        </exclude_gpu>
      </options>
    </cc_config>

This examples shows how to tell BOINC to use all GPUs but restrict the WorldCommunityGrid project to NOT use Nvidia GPU 0. Just omit:

        <exclude_gpu>
          <url>www.worldcommunitygrid.org</url>
          <device_num>0</device_num>
          <type>NVIDIA</type>
        </exclude_gpu>

to use all GPUs on all Projects.

Here is a demonstration of the effect of binning on efficiency.

 The 4070 Ti Super and 4080 Super are both based on the AD103 die. The 4070 ti super at the bottom of the stack and the 4080 Super at the top. Both working on p18220 we see Yields of 14.5 vs. 17.2MPPD:

So here's the kicker:

The 4080 Super is drawing less power while running at a lower clock speed and is still out-performing the 4070 ti Super.

In the process of replacing my motherboard so I can give my old Ryzen 1700, 16GB RAM, 650W PSU and gtx 1080 to my friends kid. Also got a spare sub 1080p screen they'll use until the friend can grab a more modern screen. (Going to be building this into a system for them, with them providing the left over stuff)

 

Anyway... I'm quite happy with this paste application

That's one nasty board. I'm still running a Gaming K7 for one of my dual folding rigs

I had one of my dual GPU motherboards fail during Folding month and so had to move the GPUs to my last two remaining spare AM4 motherboards which are Gigabyte Aorus b450m models I picked up for $80Cdn each when they were on Clearance last year.  But these boards are micro ATA (mATX) and thus could only support one GPU each.

With the 4080 Supers being better values now I picked up a couple of the Gigabyte Gaming OC models. Being 3.76 Slots wide these big boys fit with just a couple of mm to spare to not overhang the I/O connectors at the bottom of the motherboards. A case swap was also required for one system as the Fractal Define C was too short to accommodate the 342mm GPU length so the guts were transplanted to a spare Fractal Define S.

As expected these GPUs are most efficient being at the top of the AD103 stack. One even draws just 3W at idle.

Next up is the 4080 Super. I picked up a couple of Gigabyte RTX 4080 Super Gaming OC GPUs. As expected, these being at the top of the AD103 Stack they are most efficient at 2205MHz close to their 2295MHz Base Clock.

Running at 2730MHz, close to their Default Power Limit setting they consume about 275W and yield about 21MPPD. Moving to the efficiency peak at 2205MHz they consume about 167W and produce 17.6MPPD a decrease in Yield of 16.5% but a 39% decrease in Power.

Doing some research for something else I surveyed the x670e motherboards to see which ones have PCIe5 x8/x8 slots:

About the only "reasonably" priced x670e boards out there are the Asus ProArt and Strix x670e-e and the ASRock TaiChi. The MSI Carbon WiFi would be a contender but rather than shifting all the PCIe slots down 1 slot like the rest they decided to shift everything down 2-slots meaning the lower card will, in most cases, collide with the PSU Shroud.

Gigabyte appears to be avoiding having to buy re-drivers on their 670e motherboards in favor of even more m.2 slots and so are out of the running. Which makes me wonder why the Extreme and Master are so expensive.

Two of these plus the fiber you linked earlier would be perfect

No, they are not perfect. Those are 20km rated 1310nm SFP modules and will require attenuators for such a small run or you WILL risk burning out the receivers at either end. The Multi-Mode model rated at 550m maximum would be better in this use case.
