Topic: MSI Twin Frozr 3 7950 Boost Edition OC ..... ebay customer problem (Read 1004 times)

so i sold my twin frozr 7950 on ebay recently.  i got it last feb 2012 new from tigerdirect.  all i ever did with it was gaming and i never overclocked it and honestly never really gamed that much with it as most friends were still on consoles.  long story short, i didn't realize they were worth so much now, so i sold it.

so now the customer isn't happy with it saying it is freezing and crashing so i questioned how and what was going on and how they were testing for stability because it worked perfectly for me.  ive been on ebay 10 years and have 100% rating.  so they responed:
 The setting in CGMiner for 7950 boost card is "--intensity 19 --lookup-gap 2 --thread-concurrency 22400 --worksize 256 -g 1." Computer is Athlon II, 8GB DDR3 RAM, 32GB SSD, GA-990FXA-UD3 Motherboard, Windows 7 64bit, AMD Catalyst 13.12 Driver. Powered PCIE x16 riser cable with powered molex is used and plugged into the primary x16 lane of the motherboard. This card crashes intermittently during test. Since this defect is unacceptable, I would like to return the item and let the original owner deals with the warranty. Respectfully, K**** *****

im not familiar with all this crypto stuff but i have read about it.  a quick google search of cgminer msi 7950 boost turns up a thread from this forum back in nov. 13 that shows the exact settings he is using but the main settings like the core clock and mem clock he hasn't listed.  its the second entry on google.  here it is: https://bitcointalksearch.org/topic/guide-complete-guide-to-flashing-your-msi-twinfrozr-7950-321648

so now im thinking he probably did follow the guide and flashed the bios etc but he is unhappy because he plugged in some generic settings basically hes trying to run a core clock higher than the voltage can support.  it is a voltage locked card but that was fully disclosed in the ebay listing.  im curious on where i should go with this open ebay complaint case.  i would rather just help him find the right stable settings for that particular card so everybody is happy.  my worst fear is after i refund and get the card back it has some strange custom bios on the card and i have to reflash to the original msi bios so that then i can test using a gaming benchmark utility to check for stability and maybe rma it.  my gut tells me the card is fine, and they are just trying to hit the gpu lottery by using ebay to test for golden cards.
