Asus P9X79 motherboard

Something I did learn about the Asus P9X79 motherboard is that it’s really picky about USB flash drives that you use to store the ROM files when you wanna update your bios.

I made a USB boot drive with windows 8 pro ISO, so I can install windows 8 off the USB drive. You can also copy other files onto it as well like drivers and whatever else if you have the room. I figured I could also drop the ROM files for my bios, rename it and use the Flashback functionality on my mobo.  Nope. So to update my BIOS I ended up using some other USB drive formatted FAT-32 and I was able to update the BIOS. I never could get the Flashback function to work mostly due to newer Flash ROM files being incompatible with my older Bios version. So I had to download a special ROM file that updated the motherboard (almost like updating your OS) which then allowed me to use the most recent version.

Flashback is a very cool function where you can update/change the BIOS with only standby power connected. You just pop in a USB drive with the ROM file on it, press a button at the back and after a moment, bingo! You can even do it with out a CPU or RAM installed on the motherboard. Kind of mind boggling but it makes sense.

I once restored a corrupted BIOS by hot-swapping it into another motherboard already booted and forced a rom flash to get it working again. This was back over a decade ago, on an AMD Athlon XP motherboard, I had a bios update go BAD and the mobo was totally useless. I read on the web about this trick where you use another motherboard that has the same BIOS chip type that’s removable but it’s a completely different brand/make of mobo.  The trick is you boot up in DOS with the working mobo, yank out it’s BIOS chip while the machine is running (GASP!) snap in the BIOS chip that isn’t working into the mobo that’s already booted, running DOS.  Run the BIOS Flash utility with special command line switches that forces the ROM flash even though it’s not meant for that motherboard. Powered down, swapped the BIOS chips back, and it WORKED! I was totally shocked! So Flashback really isn’t that amazing when you consider this, but it’s still fucking cool.

So my P9X79 mobo’s bios is all kosher now, but I still can’t use the PNY Ram I recently bought for it. I paid only $92.99 for this PNY ram, but now when I look on amazon it’s $144! So I’m gonna return it back to Amazon, and order G-Skill F3-12800CL8Q-16GBZH from Newegg. While this ram is NOT listed in Asus’ compatibility list, G-skill’s website DOES list the P9X79 mobo as compatible. Plus there’s many other G-Skill models listed on Asus’ compatibility list, unlike PNY which no PNY model is listed at ALL for the P9X79. Also I’m using G-skill my old Core 2 Quad PC right now so I know it’s good. PNY I’ve never used before, it’s a brand name I’ve seen many times, but I will never use PNY again because of this experience.

Just goes to show if I spend the extra $40 you get what you pay for. Also always RTFM before you buy RAM for your mobo!

UPDATE:

Two weeks have past and my order for this ram has arrived, and I STILL have the EXACT same problem. Why are the PC gawds doing this to me? I don’t know if I should buy a third set of RAM or replace the motherboard. I’ve already emailed the folks where i bought my motherboard from so hopefully I can get some guidance.
