sorry about the over active spam filter issue ...
I restored your fist post
 
I've Never heard of this problem ... So I'm curious about your build
 
 
 
If you switch your GPU positions does the issue move with the Card ?

Issue moves even 'with' that only card in different rig
It is clearly firmware issue
One of my cards has newer firmware, the question is - which one and how to write it to another one
It seems like 6B works better than 66, but who knows, may they both are obsolete
That's all I want
 
Interesting, that my faulty card has higher serial number, so may be I need to downgrade it somehow from newer 6B to 66 version

I bet my emails to evga support are ended up in spam folder, just like post here 

Call CS
 
Contact Customer Service

 haha, from another part of the world

 
 
We then, I'm sure your email will get answered soon enough - depends on the backlog from the Holidays
 
I'm not sure you'd get a reply to an email on the weekend

Ok, I'll wait, thank you!

If you want them both to have the same firmware then open px1 and in the lower right corner click the little circle next to the version, then click update, then when the folder opens with firmware files click the version of firmware made for your card that you want to use so they match.

Yeah, yeah, I've heard that before, blah blah blah
How about... NO
That's what opens when I click 'little circle in right corner' in PX1 1.0.2
Where is update button, huh?
Also... what firmware? LED or iXC2? Because there are... two firmwares! Surprise!

Sorry man, didn't mean to piss you off, just made the suggestion, that's how the firmware update works on mine, if yours doesn't show the update link to click and then open a folder with firmware versions it's different.
