1) Message boards : Windows : HTTP error: Peer certificate cannot be authenticated with given CA certificates (Message 23736)

C:\ProgramData\BOINC\projects\boinc.thesonntags.com_collatz\

PUT THIS: (best for 1080)

verbose=1
kernels_per_reduction=48
sleep=1
threads=9
lut_size=17
reduce_CPU=0
sieve_size=30
cache_sieve=1

INSIDE THIS

collatz_sieve_1.21_windows_x86_64__opencl_nvidia_gpu.config

It will utilize 99-100% gpu

Run only one task at once !

Better leave tasks as they now. Bcz very long tasks 1-2 hrs or more not so good: if some error appers or interuption - you loose a lot of time and points, also very long task will heat up gpu (short tasks allow to chill gpu between them 2-3 sec gives arround 10 degree T lowering).

Read my post up. You will find there answers for optimization.

verbose=1
kernels_per_reduction=48
sleep=1
threads=8
lut_size=17 (change it and test)
reduce_CPU=0
sieve_size=25 (change it and test)
cache_sieve=1

Ok, testing is finished.
Steady output from one 1080 around 6.3 mil per 24 hrs. Card running around 1900mhz on boost, +\- 20/30 mhz. (cards not reference). You can get up to 6.8-6.9 mil per 24 hrs if you overclock them. But i prefer having some reserve for stability and temperature. So all my 5 gtx1080 will jump around 31 mil per 24 hrs. I'm specially lower the TDP to restrict gpu boost speed (it jumps over 2000) to avoid overheating and to have stable T.
About power consumption. They "eating" 230+200, 200+200, 200 W. (already got 70usd electricity bill)
T is stable. Depends on case. (also we have winter here so open window really helps) 82c max with ambient around 25c in full tower. On under other but in 1st and 3rd pci-e slots. And much lower in TT Core x5 case. One near second also in 1st and 3rd slot. With extra coolers under the top of case.
Waiting for Accelero Extreme 4 cooler for one of cards. Want to test it over 2000 mhz to see how it will works and what T it will have running 24\7.
Boinc setting as i mention before.
In old times i was having couple pc with 2x7970 in SLI (was best cards in 2012-2013). They works fine but was TOO HOT.
So for this moment 1080 beat all. And it's the best card for any use you want. Also i think 1070 will be a good choice (not reference). It will have same and even bit better results as overclocked 980ti but in general will be more flexible. And will drain less power then 980ti.
But i strongly not recommend place 2 cards near each other, or place more then 2 cards in one closed case. They will burn each other and lower gpu speed dramatically. So if you want to use 3 or more cards in one system, you need to build open farm with good air flow over it. Or room with really cool air condition.
P\S but prices for 1080 extremly high. 4k for 5 cards.

Thnks. Hope it will be resolved soon.

Wrong answer. It start happens often only last 2 weeks. So you go better find something else, donkey.

Does anyone have good and tested config for single 1080 and dual 1080 ?


SOLVED

for 96% gpu load and 6.8Mil per 1080

verbose=1
kernels_per_reduction=48
sleep=1
threads=8
lut_size=17
reduce_CPU=0
sieve_size=25
cache_sieve=1

for 95-99% gpu load with 2x1080 and 6.9Mil per each

verbose=1
kernels_per_reduction=48
sleep=1
threads=8
lut_size=17
reduce_CPU=0
sieve_size=29
cache_sieve=1

So my 4x1080 will do 27.4Mil per 24hrs peak !

I will make more testing and put them here.

PS

Sshhh.. it will be our secret :)

Thanks !
Reading and experimenting now.
Got 45 sec per WU !
If my calculations is right, i will got +2.2 million of points on each card !

Thanks. And yes i know about all this PCI x16 architecture, how it splits and counts etc.

I remove one card and run task - results is same. So PCIx lines not affected bcz it was directy connected to cpu by his built-in PCIx lines. And i can hardly belive that collatz will utilize 4gb\sec(x16) 2gb\sec(x8) 1gb\sec(x4) even 500mb\sec for 2x bcs they a bi-directed so it means 8-4-2-1 Gb\sec.
Task takes around 75-80 mb of ram so not affected by ram size.
Also task takes around 140mb of videocard memory so also not affected by it.

But i get noticed when slider of % task moves it got some frizes around 5-7 times. Fast ones like 1 sec. But on other PC's it not happening. Like something lagging.

Still got not fully loaded GPU's. I see one exit from this: to buy fast CPU like I5-K 4ghz (maybe it will affect on GPU's load), and addind more RAM (to use both dual channels, maybe it will afeect on chipset architecture CPU-PCIe-Chipset data exchange). Or maybe it just motherboard ! But it one of the best from Asus.

And what you mean by "would be faster with a slightly lower sieve size" ?

I have 3 PC.
1-I7+1080
2-I3+1080
3-G4500+2x1080
(all 1080 is identical)
On first 2 pc collatz task takes 1m23s-1m27s to complete.
On 3rd pc it takes 1m37s on both cards. (Mb is Asus z170-a, 8gb 3000mhz DDR4.)
When i look on GPU load monitor on 1 pc and 2 pc, gpu have 97-98% utilization. On 3rd pc both GPU have only 85-90% utilization. PC is clean, no any other task running.
Something like this was on 2 pc after i flash new bios, but after reflash old one, time of task returned to normal.I did try all versions of bios on 3 pc didn't help.
I think there can be reasons:
1. CPU - change to more powerful (but CPU load is 1-2%)
2. MB - ? (just like it, and only mb from other vendor can fix it)
3. Config - ? (some special tuning)

Any suggestion?
