The MB is this brand https://www.asrock.com/MB/Intel/H110 Pro BTC+/#Support

The MB is definitely the limiting factor on that. It has 13 PCIe slots, but 12 of them are PCIe 2.0 x1 slots. Probably killing your PPD just with that.

Sorry to steer anyone away from their topic, but I really want to display my appreciation and gratitude to the event organizers.

I've been an LTT fan for a long time, though I've never heard about the LTT folding team ever before, my tears dropped when I heard about the event on Wan Show.

it's wonderful that our beloved(money pit, sweat pit, dream pit, epeen pit) machines are not just our pride and joy, but may also play a part of the survival of our current civilization.

The rest are of this post are personal/national/political, and Mods may delete them when seem appropriate:
Yes, this is my first post on LTT, and hopefully it won't be my last....

I ran the first week of the event only on my personal primary rig, but soon realized I had to call a few more other local LTT fans and brothers for the cause to shed some light. Simply because, Taiwan has been grasping on its own and has been trying to help the world as much as we can, and we need more voices with us to help us, and to help us help more.

 

A tiny country in the Pacific, but a part of the pandemic.
A small portion of humanity, but may be a part of the solution.

Unfriend Unfried Unfriend!!! 

My neighbor has a Search Results Jägermeister machine and about killed me with Jagerbombs!

I do believe I can top that with this bottle which is about 50 years old from the old Harvey Wallbanger days.  An old high school buddy visited about 3 years ago and we thought we’d give some Wallbangers  a try…This stuff had “turned” and they were terrible .   Making a picture of this post must have been the reason I’ve kept it!

Oh, recursive pictures, weee...

True but still the PPD for the cost i have bought it is pretty decent and the fact remains i wanted a cheap folding rig to shut down my main rig during the night, and the time i don't use it...

 

I don't have money to buy the equipment needed as i own a house and have a average paying job...

Bunch of messy pants folders!

lol there is a reason im not showing mine...its a work in progress...50% cleaner since i  started working from home next event i will likely show some of it off...

To spec and the pros.

 

What flag to run long term for set it and forget.   My work PC sits idle by itself most nights and I want it to get good WUs but whats the best to leave it at when you rarely check?  beta?  Nothing?  advanced?

for now im sticking with advanced... would like to go back to normal but too impatient to wait for WUs

For comparison sake my single Vega 56 with a mild OC/UV and a 2700X split into 3 4 thread CPU's is able to do around 1 million a day if constantly fed with work. Whole system uses under 400W when folding.

Yeah that card is expensive for me to buy in Belgium... The US and China is rather cheap to buy cards and computer parts here in Europe all things are 20 to 35% more expensive to buy as the US is a bitch with export tariffs with the EU...

Understandable. I'm practically a bystander myself. I want to build (or buy), a true folding rig, but the funding is what's holding me back atm.

 

The funding, and my gypsy-like lifestyle... (the shallow roots part, not the crazy soap opera TV BS)

I will be writing the awards ceremony this afternoon, it is currently 1030 here so expect it in the next 12 hours or so. 

 

I'm still trying to work out the best way to deal with 250+ prizes, as in distribution. I will probably do what I always do and ask people to DM me. 

 

EDIT: No idea where I got 700+ from, thats what I get for not paying attention!

 

Can't wait for a nice break

Great job, GOTSpectrum! I had fun I had a great time, and am still folding away. Have a fantastic time on your well deserved break

The used market is bad there also? In the US a used Vega 56 can be had for around $200 USD, I paid a little extra ($260) for one with a factory over clock, bigger cooler, and RGB lighting.

Dude how do you have the money to buy 8 rigs, and so much GPU's?

My wife said I needed a hobby.

 

Slowly over a couple of years I've built these up buying things when they were on sale except for a slight bump in GPUs last fall that I put a couple of overtime checks to.

Why are CPUs so bad at folding compared to GPUs? My 3700X can only get 180k PPD on average at ~110W, while my 2070S can get 10 times more PPD (1.800K) at just ~210W

Folding benefits from the highly parallel nature of GPUs, just like gaming.

Yeah, cheap used server equipment. They've got bunch of PCIes and cores even if they're relatively slow ones that's good for the job

I must admit I did not do the math on buying used server equipment. I like to buy new off-the-shelf and using the bifurcation hack with a lower-end x570 board worked out much cheaper than threadripper with PCIe extenders. I didn't even bother with new Intel HEDT as that stuff is just stupid expensive compared to the competition from AMD these days.

my gtx 1080ti gave me more PPD(almost the same tho) on a riser with a pcie 1x slot (3.0 but in 2.0 mode) than on my main system pcie 16x 3.0. It seems that the limiting factor on my main system was the single core cpu speed. On my main system the gpu usage according to nvsmi was always below 95%, on the mining system(with riser) was almost always above 95%

Short answer - floating point math specialization and massive parallelization. Folding uses floating point math. But if I can provide a more technical example:

 

An AMD ZEN 2 core has 2 floating point adders and two floating point multipliers. In a perfect world where you could keep these 4 FP units functional all the time, using a Ryzen 3700x the math would look like:

4 floating point units per core x 8 CPU cores x 4,000,000,000 Hz (4 GHz) = 128,000,000,000 Floating Point Operations per Second - 128 GFLOPS.

 

In reality, it is unlikely that the FPUs can be fed with a suitable workload 100% of the time, so this GFLOP number will be much lower. Also, as the FPUs is part of a general purpose CPU, they are constrained by available resources within the CPU. (Other functional unit requirements, memory bandwidth, power consumption, temperature, etc) It should be noted what most of what CPUs do is executing instructions involving integer math, not floating point.

 

Now looking at one of Den-Fi's RX580 graphics cards, this GPU has 2,304 unified shaders. Each shader is capable of 2 single-precision floating point operations per clock cycle (measured in Hz). So:

2 floating point operations x 2,304 unified shaders x 1,340,000,000 Hz (1,340 MHz) = 6,174,720,000,000 Floating Point Operations per Second - 6,175 GFLOPS.

 

As much less general purpose than a CPU, a GPU is optimized to perform floating-point math calculations (heavily used in 3D graphics) very efficiently. GPUs can execute a lot of integer instructions too, but their raison detre is floating point power.

 

Does this explanation help?

I am sorry, but I will not even bother explaining you anything as you are rather stubborn.

I'll just say: THIS! 

He is 100% using x1 riser. Bottleneck is at least 40% per card.

atleast that, im a converted miner and the 1x risers destroy the bandwidth to the point of not being worth it.  I ended up doing exactly what gorgon suggested and split them all on pci 3.0 4x slots through m.2 adapters.  Any card under a 2080S is fine, dont try running a 2080ti like that....

 

Honestly get a normal cheap mobo and just run 2 of the cards, it will be the same or more PPD consistant and less power usage than the 6 of those cards on 1x risers.

[hihihi8]

I'm honestly surprised at jow many SR-X's popped up recently! I've got a custom water cooled one just sitting there for years now, been thinking of selling it but its my precious at the same time

multiple low tier (cpu/mobo/ram) systems running 2x cards = better performance than plugging a bunch of boards into risers and bottlenecking yourself.  just my experience.

@GOTSpectrum, when you do the awards ceremony.  Don't forget to include the amount of alcohol you consumed as a winning stat!  

 

Feel better before worrying about writing it though.  An extra day or two to get a free game key isn't going to kill anybody.

[Rune]

Well, machines at work are getting 1/10 units of normal so its as good a time as any to take them down in preparation of phase two.
