Nvidia GeForce GTX 1070 Max Memory Clock / Transfer Rate

$
0
0

I am confused with GTX1070's Max Memory.
According to my screenshot below from nvidia-settings:



The above is when there are no offsets applied to either GPU or Memory clocks ( e.g. stock standard values ).
If I apply a memory offset of +450 MHz, the "Memory Transfer Rate" at the Performance level 2 goes up to 8054 MHz, so does the "Memory Transfer Rate" at the PowerMizer Information section.

However, when I run nvidia-smi:

$ nvidia-smi --format=csv --query-gpu=clocks.current.memory clocks.current.memory [MHz] 4032 MHz 4032 MHz

... it shows my memory is only at 4032 MHz.

Thus, my questions are:
  1. Why is nvidia-smi only showing 4032 MHz ? Which tool is showing the correct answer ? nvidia-smi or nvidia-settings ( via X )
  2. Has anyone been able to set the performance level to '3' ( highest performance ) ? Even if I select "Max Performance" instead of "Auto / Adaptive ", it goes to level '3' .. but goes back to level '2' after a few seconds. When I start mining, it still stays at level '2'.
  3. Has anyone been able to set memory clock to 8008 MHz, which appears to be the maximum allowed ?
  4. Lastly, I read a lot of sites which states that P0 is the highest performance, but the nvidia-settings output is showing the other way around. Which one is it ?

3GB Mining Rigs stopped mining ETH/ETC

I have several rigs with whicht I have been mining ETH, they have all been working well untill yesterday. Each machine that has had to restart the miner or do a complete reboot will not load the DAG anymore. The rigs that didnt reboot/restart miner yet are still mining ETH. From what I gather the DAG should be ~2.4GB right now which shouldnt be a problem for these cards.

The error message when miner starts: Cannot allocate big buffer for DAG
All rigs have GTX1060 3GB cards, Using the Claymore miner (Phoenix has same problem) and the Virtual memory is set over 16GB.

Does anyone have any ideas why this happened?

The best cloud mining services:
HashFlare- http://bit.ly/CloudMiningHashFlare (promo code HF18SVALDAY get 10% off! awesome!)
Genesis Mining- http://bit.ly/CloudMiningGenesis
CCG Mining- http://bit.ly/CloudMiningCCG
I just didn't expected that promo code! such a surprise! Damn! It is cool!
I would also recommend to check out the decent cloud mining journal http://cryyyptomining.com best articles about that!
for instance something i understand from that journal is the matter of the process of cloud mining operation

Cloud mining is a complex service that sells the powerful device, ensured by enterprises that own mighty data centers. It’s kind of investment of money for mining of crypto money with help of powerful blocks forming blockchain.
These days there are three most widely used cloud mining methods:
* Hosting – platform where owner provides equipment to rent for cryptocurrency miners.
* Virtual hosting – renting of area on the server with following installation of tenant’s software for cryptocoins mining.
* Lease computing capacity of the server without opportunity to regulate its operation.

check that journal on that and other topics.

Rx 480 Sapphire nitro+OC 4gb modded to 8gb (31 mh - 1225/2200 mhz )

$

Hello,
I am relatively new to mining and for the moment I only have one GPU to experiment with and that is Rx 480 sapphire nitro+ OC.
After reading lots of forums and after lots of tries, I've come to understand how to mod my bios, flash it,unlock 8gb on my card,timestrap memories.

I will make this both a guide for newcomers explaining every step to make and a discussion on the settings I've come to so far since I'd be happy to know if they are safe or efficient.

GUIDE
First i'd like to mention that Rx 480 sapphire nitro has a dual bios with a switch to "silent" bios mode near the led button . The position closer to the HDMI ports is for the silent bios. So if you accidently break it you still have a chance to revert the mistake.
What you need
Polaris bios editor (PBE) http://www.overclock.net/t/1604567/polaris-bios-editing-rx480-rx470-rx460
Ati flash 2.74 https://www.techpowerup.com/downloads/2728/atiflash-2-74
Amd catalyst center version 16.9 or 16.11 other versions need to be patched to work with modded bioses as they check for the bios signature and will deactivate the card http://www.sapphiretech.com/download.asp?lang=eng .


How to do it


From what I read every Rx 480 sapphire nitro 4gb is in fact 8gb, but let's say that information is false, if you see this black sticker on your box it's safe to say it has in fact 8 gb.


To unlock the 8gb all you have to do is install ati flash, open it as administrator, save your current bioses ( you will need them later, you can change the position of the bios switch even when the PC is working)
Now that you have the original bioses saved make sure you do not lose it as only with them (or with modded versions of them your GPU) will work, so in order to test my bios or one from the internet you have to copy in PBE every setting to your own bios file.
Open PBE and modify the memory size from 4096 to 8192.
I'm sorry but I currently do not know if you have to modify the density as well, so I'll say leave it as it is.
Now save it and flash it with ATI Flash on your "silent" bios. If you break it, you have to switch the bios, boot in windows, switch the bios on the broken one, start ATI Flash, and flash a good copy of bios.

That was unlocking the 8gb. I do not promise you will have greater hashrates or you will notice any improvement at all. For me it was the opposite, I noticed a decrease in my hashrates and in performance overall. And here comes timestrapping.
Timestrapping in short is modifing the times of the ram cycles. At lower frequencies there is a lower time for the cycle and at higher frequencies there is a higher time for a cycle. In PBE you can copy the times from lower frequencies to higher frequencies so you have tighter times between cycles. From what I read some copy the timing from 1600 mhz to those above. For me personally that didn't work so great.

I hope I was clear and this helps anyone. Now let's talk about settings.

SETTINGS
As I am part gamer too and as I do not have the best power supply yet my safe settings are 1225/2150 for 30MH. If I am running any game while mining I notice small framedrops from time to time while I get 26-28MH.

For mining only I can push the limit to 1225/2200 where I get 31MH.





I mention that the bios I use is still under testing. For now it is the best I have. I have tested other bioses from this forum and not all of them work for me(the console reported 30 MH but after hours of mining the shares found were the same as if i had 16-20 MH) but they have inspired and helped me. The bios that helped me the most was v4 from Jukebox, you can find it here https://forum.ethereum.org/discussion/9650/sapphire-rx-480-nitro-oc-8gb-11260-01-20g-modded-bios-29-mh-downvolt/p5 .

Density of memory is the original one 0x53.
I have timestrapped all the frequencies.
Downvolted to 900.
The GPU runs on 85W.

BIOS originally dumped with AtiWinFlash 2.74 on "silent" BIOS jumper position.
Modified with PBE (polaris bios editor) 1.4
Clocks 1125/2080 tuned to keep GPU and mem controller load maxxed.

Cooler profile - unmodified

Flashing and installing procedure can be found in Boysie thread.

It's strongly recommended to flash your card, when BIOS jumper is on "silent" position - when jumper moved to DVI/HDMI connectors side.

You can also use Sapphire trixx, wattman or something else you want - to modify voltage (in most cases it can be lowered), clocks and cooler profile.

BIOS seems to be stable, but use it on your own risk and make backup of your original BIOS before any change/flashing.
If you forgot to do it, you can find it here.

Joke! Even if you do something wrong and catch some troubles - simply boot your system with "default" BIOS jumper position. You can switch it on the fly after booting your OS and flash your original unmodified BIOS.

PCIe slot not working after GPU flash

ahoy,

I've got 12 of the same memory (hynix) 580s. First 6 work like a dream, flashed them all with the same bios and it worked perfectly.

On to the next rig, it plug everything in and it works straight away, detects all 6 cards.

I flash the cards with same bios as before (same memory, same brand, purchased together) and now one of the pcie slots fails to show up in windows.

The motherboard I'm using (tb250-btc pro 6 gpu ver) has a post screen that shows if your pcie slots are working, faulty or not being detected.

The motherboard post screen shows everything to be working fine, but windows won't detect one pcie slot since the flash.

The riser/gpus work perfectly on all other pcie slots, it's just this one that windows has decided to forget.

Thoughts?

When do cards wear out?

Elephant in the room time, GPUs ain't made for mining. Running them 24/7 was never the plan.

Surely there is a line in the sand where they start to become less consistent?

Context; my first rig has been running for almost 10 months solid with downtime that can be counted in the minutes.

Hashrate average is stable, but most of if not all the cards drop randomly every few shares.

Say 30mh to 20mh, to 30mh to 12m etc

Can we/am I, running my cards into dust?

Note: Heat has been on average 20-30 degrees below max operating.

I've been running geth --mine for around 24 hours. I'm running it on a Mac OS X 2.7 GHz Intel Core i5 with 8 GB 1333 MHz DDR3. Apparently, I've managed to mine 4 blocks for a total of 20 ether. However, given everything I've read vis-a-vi difficulty and GPUs, I'm not sure I believe that. How can I check what network I'm running geth --mine on, and whether my ether coinbase, Address: {a0818b21e0989192d57926d173a5f25c501ff3d7}, is a real address containing real ether?

I have a nice ubuntu image I created that I can copy to my ssd's and just boot and run. The only problem I'm having is successfully overclocking.
I have tried
echo -e "high" > /sys/class/drm/card0/device/power_dpm_force_performance_level
echo 10 > /sys/class/drm/card0/device/pp_mclk_od;
echo 3 > /sys/class/drm/card0/device/pp_sclk_od;

and variations of that but still only getting 25 MH/s out of my 470s which can easily do 28 MH/s on windows. I don't want windows, I want the option to run 7 or 8 cards and with windows I cant even run 6 -yes I ran the patch and disable all the crap in the bios, it just locks up.
besides, my ubuntu boots up in 8 seconds :-)

Claymore unstable hashrates

Hi all,
I’m quite new to gpu mining and I build myself a rig from some parts i had laying around. However I can’t seem to figure out how to get stable hashrates.
Setup:
Asus p8h61 mobo
Intel pentium 2.7ghz
4gb ddr3 ram
Kingston ssd v300 60GB
Corsair cx600m

Sapphire pulse rx570 4gb elpida bios modded
Asus strix r7 370 4gb
Sapphire nitro r7 370 2gb

I’m using the crimson beta blockchain drivers.



As you can see the hashrates are fluctuating quite a bit. I already upped the virtual memory to 16gb but that didn’t help. Tried running on stock clocks and speeds, but the result stays the same.

Also the sytem doesn’t run stable at the moment, it seems to randomly crash. Sometimes after 3 hours and sometimes after 15 mins.

Hope you guys can help me out!

Hey guys

I just built a telegram bot to help people monitor their rigs across multiple pools and coins. For now, the bot has these features:
- notify you if your miner goes offline
- notify you when you receive a new payment from the pool
You can also check in real time the current statistics of your workers, pending balance and see your payouts history.
New features are also planned and will be added soon

Is web3.eth.hashrate broken or my CPU is ?

$

Hello all,

I was playing with eth when I found out that when typing > web3.eth.hashrate returns only ~240 000 when mining with my CPU with 4 threads (can't test on GPU), whereas on geth, > eth.hashrate returns ~1 400 000. Since, to my knowledge, eth is supposed to be slightly faster than geth, it kind of suprises me.

We can multiply the result of web3.eth.hashrate by the number of threads to get closer to geth's hashrate in the case that eth returns only one thread's hashrate, but we are still way off.
Why such a gap ?

Thanks :).

The option is not available with any version of Adrenalin I've tried and system hangs if I try using Blockchain Beta release - what gives?

The DUAL version card I have has a smaller cooler and no backplate - is this related? I bought it becuase I wanted to mine in my toight HTPC chassis when it was idle.

MSI Gaming 580 8GB - over 30 MH/s ?

$

Dear All,

Recently I have bought some new 580's(Nitro+ & reddevil) and they overclock so easily.

The problem is that I have many MSI 580 8GB Hynix and Samsung that will only reach 28.2 Mh/s and 29.4 Mh/s respectively.

I have even taken one of the cards apart to improve the cooling as the thermal tape was poorly applied. I even added some mini heat sinks above the memory chips - Made no difference

I have also tried many custom bios and millions of Claymore tweaks.

I always end up with the same problem where if I increase the memory speed over 2000, I get memory errors as seen via HWINFO.

Had anyone got these cards running efficiently over 30 Mh/s ?
