"Important News For ASUS Crosshair V Formula Motherboard Owners I have contacted ASUS pertaining to the CPU/NB LLC problem and it turns out that it is not the bios. It turn out the bios chip is faulty. He asked me when I got my board and I thought this was kind of weird so I asked him why he needed to know after I told him. It turns out that Crosshair V Formula Motherboards that were purchased before a certain date have a faulty bios chip on them that is affected by the FX processors. He did not tell me any details but they are sending me a new bios chip that has been fixed for FX cpu's. I am a little disappointed that I was not notified or contacted about this seeing that they know that I have this board with a 8120. He did not tell me the date of which the boards started being fitted with this fixed bios chip but if you have an FX processor with this board then I would recommend contacting them and requesting a fixed bios chip for the Bulldozer cpu. Hell, I would even do it if I didnt have a FX cpu. He did say that the boards that were sent out before a certain time had a faulty bios chip that was affected by the FX chips. Not exactly, but something right along those lines. If you have this board I would recommend calling them and asking about this cause you might not be getting the most performance out of your board and chip because of this. He did specify that it is with the Bulldozer chip but he did not exclude and chips. So I would call and find out if your board is eligible for a new bios chip. I purchased my board in october. I had to tell him that and the serial number to, i guess, see if my board was one of the ones sent out with a faulty bios chip. It turns out that it is and he said the new bios chip fixed for the FX chips will be delivered to me within a week. Nice customer service I might add. I dont know how or if this is going to increase performance or stability or anything like that and I will be sure to let you guys know once I install it. So, IMO if you have a Crosshair V Formula mobo, then I recommend that you call ASUS (U.S. Toll Free - 1-812-282-2787) and find out if your board needs a new bios chip. I am glad that I found this out. I dont know if the faulty one was damaging anything or decreasing the performance of my chip or affecting stability or what but a faulty bios chip needs to be replaced. OP, I think you should post this on the first thread for other Crosshair V owners to see. If you have any questions or concerns please feel free to ask. Hope I could help you guys and I will notify everyone, once I install my the new bios chip, if there are any performance or stability changes with it."
