Sometimes it is also connected to the core:mem clock ratio, I had cards which were stable at slightly higher clocks than in lower.

I mean you could try using a different (PCI or PCIe) network card and see if it helps. If you have time you can try if the same problem happens on windows.

Different network card?

Looking for a cheap datacenter in central Poland to house my rigs, can pay for 6 months in advance after a 7-day trial period.
Few squared meters and up to a few thousand kWh per month is all I need.

4000 dollars in one month? wow, didn't know anyone could get so much money from donations in so little time in such a niche field as a bitcoin wallet application.
Congrats!

I'm not buying anything form Sovereign Investor unless I have proof the stuff he is selling is legit.

So far I have no reason no perceive him as a credible person, he doesn't even seem to be able to do something as simple as I wrote in this post to dispel the doubts:

https://bitcointalk.org/index.php?topic=69147.msg810975#msg810975

I see you know him personally, do you think you would be able to extract (doesn't matter much how) the money from shakaru? I'd be willing to part with 15% of my debt, if everyone agreed, you could earn over 3250 dollars (more if the price of BTC increases).

At such a low clocks you should be able to reduce the voltage much, much more.
Not sure which software will work though without BIOS flash but you can give a try to all the tools available.
For me barelyclocked works well for undervolting/overvolting all cards.

HD 6770 - works 24/7 stable @ 775/180 with 0.82V (stock was 775/1000 and 1.125V). This way temperatures decreased by 27C (the card is in a very hot place).

If your account is in EUR doesn't your bank support SEPA transfers, they are usually around 1.25€.

Is this a 2 GB model?

Payment and PM sent, might take a while because fee was low, thanks.

0.01337 BTC

You sure it is worth to overvolt considering the extra power draw?

looks nice btw

Depends on the drivers'/miners' cpu usage and the mobo and cpu themselves.

I have gathered some information about him, you might find it interesting/useful.
I don't like him one bit because of people like him my compatriots abroad are often falsely associated with scamming so I decided to share some info, not much, but it might be helpful. I will update this post when I find more info.
Sources: mostly google, bitcointalk.org posts, forum.bitcoin.pl posts, Tor forum posts where he tried selling Bitcoins and hardware for PP, BTC and wire transfer.

Uncovered IP address: 91.221.214.191
Users on the tor forum found out his ISP is JMT Elektronika Marek Wensierski (via VOLTA-AS Volta Communications Sp.z.o.o. with ASN number 39816 located in Banino 80-297 on Mazowiecka 6 and Klonowa 25, it is close to Gdansk (Danzig) in northern part of Poland. It is a small 2^9 IP network.
Coverage of his ISP: http://gdzienet.pl/preview/jmt

On their website they say they deliver Internet services (over fiber and licensed/unlicensed radio freqs) to following locations:
Gdańsk Osowa
Banino
Barniewice
Czaple
Chwaszczyno
Rębiechowo
Pępowo
Małkowo
Klukowo

He listens to rap - RPK and Ten Typ Mes (lyrics in his signatures' posts on onion forums).
His rap song (?) on someone's wrzuta account (female friend I think): http://askas.wrzuta.pl/audio/0NQI91GIJkN/dareq_-_pierwsze_spojrzenie

Dareq who also goes by a nickname Bago is a Pole residing in Poland or UK (once contacted him and was told he ships from UK and he seems to be quite fluent in English and it's not so common in Poland)
He frequently used/uses his hotmail account: tentypmes@hotmail.com
and on Tor: bago@tormail.net
It is possible he did not secure himself when connecting to hotmail because he gets angry when someone reveals his identity on Tor.

It is possible his firstname is Dariusz (Darek is a diminutive), because it is not uncommon for Poles to replace 'k' with 'q' in their online identities so be careful when searching through the deep web and clear net for his nickname.

I think he is 18 or 19 years old but I need to check it.

This is his allegro account feedback:

This might be his another account but I am verifying it now:

A quite a few items are related to scuba diving, skiing, and network stuff in bulk qt, if you want to see more use a google translator unless you understand Polish and use this site to see archived auctions:
http://archiwumallegro.pl/szukaj/

Next to the date of each item he bought/sold with his allegro account there is a number, copy that and paste at the above website to see what was the item.
With that you may learn a bit about him.

But remember he could be using a stolen identity all the time, VPN, someone else's PC, etc.

More around the end of the month, I am really busy recently.

lol i geddit

you are a scumcoin supporter, am I right?

Try either OS X on a VM or Hackintosh, Macs are waaay overpriced but it is because so many people are willing to buy it (convincing marketing?) Cpt. Obvious i know
