AMD OpenCL Momentum miner

can anybody tell me:Whats the best safe memory gpu and core speed for r290?

There is no clear-cut answer to that as it all depends on your GPU(s). Literarlly,
even between same make/brand/model the ASICs can very. Also, make sure you
have the powersupply(s) to handle the increase as jumping up clocks a little makes
BIG differences in power draw... which is why it's smart to under-volt but then again
if you're under linux (like myself) then the capability doesn't quite exist..

Having said that, my MSI R9 290 Gaming GPUs are over clocked to 1050Mhz/1350Mhz
with PowerTune @ 20% and I keep the fans on constant 85%. The rig run stable though
gets a little toasty with temp ranges from 74C to 81C. It would have been worse had I not
taken off the factory thermal grease and replaced with mucho better grease. Any clocks past
that I found to be unstable given my make/brand/model of GPU.

LAST IMPORTANT NOTE : I run clpts at those clocks. If you try those clocks with cgminer for
other scrypt mining, you better have 350W+ for each card. NaN's clpts is very efficient and
doesn't run as hot as cgminer's less efficient algo. Good luck!

Having only reference cards (2x r9 290 from sapphire and gigabyte), I can tell on my side:

- gpu clock: 1125
- mem clock: 1300 (but 1270 seems more stable)
- undervolt: -44mV in MSI AB
- fan speed: 63% (ambient room temp around 20-21 degres Celcius) to maintain temp of the cards around 63 degres celcius

A bit loud but works well xD

Today I tried power meter to compare PTS and scrypt mining. I have in one rig 3x7950 and 1x7970 and in PTS mining they consume 800W with scrypt 900W.
In the second rig I have 3x280x and with PTS mining it consumes 560W, with scrypt 760W.
All of my cards are tuned via BIOS and undervolted. Undervolting gives you 30W and 5-7 degrees Celsius less per card, which is acceptable for the labor to edit BIOS-es.
My 280x are running at 1020/1500 with 1131mv, even to overclock them to 1090/1500 with 1225mv it doesn't give me more CPM.

any update to suport muli-pool?Ypool always disconect

Guys, what is the kind of CPM to expect on a 280X?

I get around 3373 c/m at stock 1000/1500 and 3500 c/m at 1050/1500.

Hi, thank you for this miner. With ubuntu i have a problem.

After few time the miner stop to work. I have "Connection to server lost - Reconnect in 45 seconds" but the miner close in my console without try reconnect.

Code: [Select]

collisions/min: 0.0000 Shares total: 1872
collisions/min: 0.0000 Shares total: 1872
collisions/min: 0.0000 Shares total: 1872
Connection to server lost - Reconnect in 45 seconds
Aloec@pc4al:~/Desktop/min$

I dont know if it is my .sh file who bug. Here is my .sh

Code: [Select]

./clpts -u aloec1.pts -p x -t 0,0,1,1,2,2,3,3 -a 0

If you can help me please.

Hm, ypool is heavily DDOSed today and something does not work because the miner shows 0 cpm. I do not know whether this is a bug in the miner. Could you send me additional information about your system via PM so I can investigate this issue?
A workaround would be to modify your script so that it restarts the miner every time it exits: while true; ./clpts -u aloec1.pts -p x -t 0,0,1,1,2,2,3,3 -a 0; done

Thank you for help Nan, i send you a mp.

if i can manage to flash my r290 to r290x .Am i going to get 4500 cpm with this miner?Getting around 3900 atm

One or two days ago the difficulty more then doubled from 17 to 36. That is the reason.

[maddi]

i monitored it for 24 hours.. but i got only 0.70 .. confirmed and unconfirm

[flo2005]

NaN do you have plans to release more optimized miner for PTS, if yes when it can happen?
Is there possibility to add temperature, fan % and voltages for the GPUs in the miner?

Regards

because voltage regulation is a serious lack in linux AMD drivers and we all know that cards don't need that much volotage to run... even OC... Thanks a lot

http://sourceforge.net/projects/amdovdrvctrl/?source=navbar

allows you to change voltage unless your card is factory locked in which case the BIOS will have to be edited?

Tried but it says that some functions are not supported by either your hardware, the Catalyst driver or the ADL. List of problems: failed to get fan speed infos and Overdrive parameters. Which makes no sense since OD is activated because both cards (r9 290) are OC and works perfectly. Fan speed is also manually adjusted by command. Didn't manage to get the info if the last available version supports r9 cards or Catalyst 14.1 beta for linux... Any idea?

I personally don't know, I run windows, I was just trying to give you an option heh... I'm not sure the 290 series can have the voltage changed without directly accessing the BIOS, and I'm not sure anyone has made a good utility for the 290 series yet (I've seen people ask like crazy but never a good answer)... the 280 and below are cake to modify the BIOS if locked...

I used to be on W8.1 and switched to linux to "insta gain" 1k cm/card. Anyway when on Windows I was able to tweak the voltage of both the cards (saphhire and gigabyte) using MSI AB. So I was wondering why I can't on linux whereas it seems people are ok with that on their side. But I guess r9 29x and not well supported. Only 7xxx and r9 up to 28x series at this time...

FYI I have 2x r9 290 on ubuntu and 8k cpm. Doing 0.8pts a day on ypool.
