Sabertooth 990FX R2 and AMD FX-8350 won't post

kkragenbrink · Jul 15, 2014

I have been running an AMD Phenom II X4 960T for about a year now, and tonight I decided ot upgrade to an AMD FX-8350.

When I plugged the 8350 in, I could not get the machine to post at all (no beep on my speaker).

I currently have bios version 2501, and I was able to return to my 960T with absolutely no problems.

Do I have a bad CPU or did I miss something in setting this up?

do the fans spin? if yes do they stop after a few sec and start again? like pc is rebooting? if u get the old cpu in again does the pc boot?

Bios is valid for 8350. If old CPU is ok - Must be the new CPU problem.

watafak :

Fans spin fine, lights come on, there's just no post. It behaves as if there is no CPU. The old CPU works fine.

Try clearing your CMOS battery. Leave it out for 3 minutes. Put the CMOS battery back and try the process again from scratch. Re insert gpu and ram stick. Use a different ram dimm or a different slot. Make sure nothing else is hooked up like USBs

maybe its a bit extreme but is ur psu enough for fx 8350?

kkragenbrink · Jul 15, 2014

watafak :

Yeah, PSU should be fine. 850w PSU, even if I am running a pair of GTX650TI Boosts in SLI mode w/ 16 GB of Ram I'll try reducing down to 1 DIMM of Ram and 1 GPU tonight when I get home, just to be sure, but I'm not optimistic.

also if u mobo has IGPU try to post with gpu's on it.

romirez · Jul 15, 2014

watafak :

No igpu!
Why not to check that before posting solution?

(from mr Beezy )Try clearing your CMOS battery. Leave it out for 3 minutes...

3 minutes? Never heard of that kind of clearing CMOS in my long mobo reworking practic . 2 sec is enough!

P.S. Just test new cpu on another 100% working mobo.

romirez :

If I had another AM3+ mobo laying around, that would have been the first thing I did. I'm considering driving back to Fry's and having them do it. If it works, I know it's me and I'm out a little gas money. If it doesn't, I am already in the place I need to be to replace it. Just seems a hassle.

So, turns out it was indeed a bad proc. Went back to Fry's, got a replacement, dropped it in, and I am now humming right along.

I had the same problem, The asus sabertooth 990 fx 2.0 have some red lights, when you turn on the pc it will make a quick test, if you see a red light that keeps on, that means taht something is wrong with that, there are different red lights and each one means something, if is just down the cpu and to the left of the memory ram, it is the cpu. if you take a look closer youll see that it says cpu. the same with the other red lights have the name of the device tested. In my case i just had to move a little bit the fx 8350 and it works.

romirez · Sep 16, 2014

Red light near CPU means only *CPU ---> <--- MOBO* problem, but solving that problem is another story: by bios or by CPU or even pins in socket.
