I only get 50% of the PPD that people say they get 1070 ti

Post by ARAUJO »

I started with 2 1070, 3 1070 ti and 1 1080ti approximately 4 or 5 days using i7 6700k 16 RAM Win10
I am using the passkey, media from 2000 to 2050 core, 3800 to 4000 memory tdp 80% testedi drivers from 388.13, 417.71, 430.64 now I am at 419.67 all uninstalled right with DDU
I made several attempts of new configurations that I saw in the forum and my points are low

my average overall PDD ranges from 1 500 000 to 2 000 000 with the 6 plates
I've seen several people talking about having an average of 600,000 or more per similar board
so it was for my PDD to be close to 3 600 000
I've tried a lot of things I read in the forum and I can not increase my points
I am using the passkey, media from 2000 to 2050 core, 3800 to 4000 memory tdp 80%, 90%, 100% I made several stops to try new configurations and my points are low
USER ID: up7o1dvd8ko1
TEAM ID: 234980
I put it to run a few hours in another hd with another installation of win10 to see if something changed but it is the same thing
if someone can help me I will be grateful sorry for the English I am using google translator and I do not know if I posted here in the forum correctly I never did any post but could not find
Solution and I need help, please.

Are all 6 cards in one computer?

What motherboard?

Each card will need at least PCIe Gen3 4x to get good performance in windows and a core (thread) free.

If you run into pcie bandwidth limit then running Linux instead of Windows may improve it.

I am using the MB Biostar pro BTC 250 with 12 slots
I did mining of crypto coins with this system using 12 GPU now I'm only 6 gpu but I can not get the expected result with them here
my 6700k i7 processor has 8 cores so if it's 1 core for each board I would still have 2 but I tested the same system only connecting 1 1070ti and I get 300,000 PDD average almost half of what the staff says it earns
This is not to mention when there is not a long period well below

The problem is the pcie risers slots bandwidth limit. Be sure to have in BIOS set pcie 3.0 or gen 3. And Linux improves performance compared to Windows.

That Biostar pro BTC 250 motherboard has 1 x16 PCI-E slot and 11 x1 PCI-E slots. All the x1 slots will be bandwidth limited. The x16 slot should perform fine.

Even Biostar advertises GTX1060s for mining on that rig.

Your gtx 1080ti needs to go into x16 slot, the slower cards to the risers.

my 6 GPUs are connected in risers. You tell me to connect the 1080i straight from the motherboard in the x16 slot and the other ones by the risers will it make a difference in the PDD?

It will improve the card you move to the x16 slot. Improving the cards you leave in the x1 slots will need Linux, at least until Core_22 comes out.

so if I put it to run on linux with this config I will be able to receive close to 600,000 PDD per card? even using the risers at x1?
sorry for my unexpectedness rsrs...
if the answer is yes I still install linux

x1 is insufficient bandwidth to get full performance out of a good GPU, even in Linux, but the Windows overhead makes it worse until Core22 is available. Most WUs do a lot better with x4 or above.

When people say they're getting N PPD out of their X GPU, they are telling you a number that assumes ideal conditions and often includes overclocking -- and it probably doesn't apply to all projects. An x1 slot is NOT an ideal condition.

Please, excuse me one more doubt.
even if the inputs x1 of my motherboard is 3.0 = 1gb / s is not enough? would be similar to an input x4 1.0

There's a long discussion (18 pages) about PCIe bandwidth limitations here : viewtopic.php?f=38&t=28847 ...

The 1070 ti supposed to get around the same PPD as the 2060, ~1M PPD.
On a PCIE 1x slot, you'll get a ~15-20% lower score than on a full 16x slot (so you'll still get between 700 and 900k PPD).

You're a fairly new user, so the bonus points might not yet have accumulated at the time you wrote this thread.

MeeLee's numbers are for Linux only.

I tried with pcie 3.0 x1 riser and get 800k PPD for a gtx 1080 (~= 1070 ti) limited to 110 watts using Linux.
gtx 1080 at pcie 2.0 x1 gets 800k PPD same as pcie 3.0 x1.
gtx 1070 (non ti) at 110 watts gets 600k PPD.

RTX 2080 at pcie 3.0 x1 gets 1.6M PPD => no bottleneck
RTX 2080 at pcie 2.0 x1 gets 1.2M PPD => bottleneck
RTX 2080 at pcie 1.0 x1 gets 900k PPD => more bottleneck
