Win 7 BSOD BC Code 50 fileinfo.sys page fault in no paged area

After 34 Hours of continuos memtest. Its come back with more than 445,000 errors. This is with all the four slots populated with 2GB RAM Sticks from G Skill. This is the first time i have bought G Skill and guess what i think about them after replacing 2 of the faulty modules that came up with errors straight away. Where as now the errors showed up after aout 6 hours into the tests. Not sure how am i gonna explain this to the retailer but i am flipping livid now.

Thanks for your time Jonathan King, really appreciate your help. i had posted on this forum as i thought the issue would be driver related but it clearly is not. I dont thing i would be getting replacement. i will just want another brand or a refund.

Thats what i think the problem is but i dont know how to replicate the issue as it takes so long for the errors to show up and there are 4 sticks
and seriously something is foo bar and i cant be asked to waste more time on this. I am going to the retailer tomorrow who isnt anywhere close but >50Km away and show him the photos i took of memtest errors. I am going to ask for a new board and different RAM (corsair maybe) I have had BSOD for over a month and lost so many hours.

Can you guys confirm that this ram F3-10600CL9D-4GBNT is compatible with my board? ga-890fxa-ud5. on the product page it does not list the chipset as supported.
G.SKILL-Products

Just got the RAM replaced with Corsair. ran memtest and no errors initially. will run it again over the weekend for at least 2 days and nights. Thanks for your help guys. Wont be buying G Skill again.
