970A-G/3.1 vs 990 fx ext6

Another restart and gone again...no Toshiba help til next year either~

so....after the whole re-finding .. the repairing ..I figured I was gtg and started DL'ing my free gears of war4 game from Microsoft store (for buying my vid card) this process happened at a blazing ...less than 8gig per hour DL rate, tho I think it was installing at the same time? so may have been a factor I dunno..I had DL'd it before to old machine and took near same timeframe...8+ hrs anyways.
So after 10+ hrs and it seemed stuck at 73.10 of 84.90 gig done...I paused it and restarted .... everything... router/modem and comp....


It's gone again..... M.2 slot in uefi system browser is Empty!

Tried the repair option on the NVMe driver install ..no change.....

Bad drive?...

Yes it also disappeared from the 990 board, gone from windows and uefi system browser. Did not remove power just shutdown, and it never reappeared on the 990 board again ,left it on the card in the system for a week...several shutdown and restarts no change.


Just meant that after installing the software tool it showed there on the tool like it should I was able to run a benchmark on it and all seemed fine, said it was 100pct healthy etc.


However....because I only had a 120g ssd due to the rd400 disappearing I decided to throw in another ssd .As it was booting up a cpl messages appear saying my computer had probs and was being repaired , this is while the ASROCK logo and the spinning thing are happeneing , it did its thing and now its back......for now

All up and mostly running okay with but one disappointment so far.
I was reading the spec sheets on both and the only two things that seemed diff between them was the FSB 2400 vs 2600 and the amount the ram could be OC'd 2400 vs 2450,but then the *lower end* board gets usb 3.1 and the thing that caught my eye was the M.2 slot being gen2x4 vs the 990's gen2x2. Assuming the FSB and ram oc caps are kinda connected and probably the main *difference* between the 970 and 990 chipset and the usb and m.2 being just a ...date of manufacture / available tech atm thing?
Unfortunately my ocz rd400 M.2 drive disappears after a shutdown... restarts after installing it and the ocz software didn't effect it I ran a benchmark that came out as it should , 1.5~ish gig read lil over 1 gig write.Downloaded a game onto it, well over an hour, played the game for a few min . Logged off did a few other things then shut it down for the night, next morning it was gone. Now I'm guessing it's the drive as it also happened in a very similar way when I put it into the 990 via an AiC.
Two other differences ive noticed the Bios on the 970 is the same P1.20 that my 990 came with, but the 990 had an update to P1.40 that is not an available choice for the 970, P1.40 says it adds usb stability, M.2 support and NVMe support...that part is a little confusing , faster slot but not/less supported?
Other thing that caught my eye was in the AXTu ui...on the 990 I have an intelligent energy saver option where it will switch to 4 phase power...not an option when loaded onto the 970.

Again my thanks...yea I have no thoughts on going the 9 series chip unless somehow ryzen becomes a total flop. Any thoughts on OC'ing this 8320 on this board as opposed to the 990?
