M5A97 EVO R2.0 Can't flash BIOS

hcccs · Dec 20, 2015

I just put together a new PC as follows:

Case: Antec ThreeHundred
Mobo: M5A97 EVO R2.0 (used)
CPU: AMD FX-4100 (used)
Load disk: SanDisk Z400 SSD
Cooler: AMD
Memory: Corsair CMZ8GX3M2A1600C9 2x4GB according to QVL
PSU: Corsair TX850

When I start it I get ...
CPU LED is red
All fans and disks are spinning
No beep
'No signal' on screen and then black screen.
When pressing the MemOK switch the led starts blinking and doesn't stop.
The 8-pin CPU power connector is properly seated.
I have removed the battery to reset.

I don't know what CPU was used previously with this mobo so I thought I needed a new version of BIOS. I downloaded the latest BIOS, M5A97-EVO-R20-2603.CAP, as per ASUS list. I renamed it M5A97E20.CAP according to manual and put it on a USB stick, formatted with FAT32. I inserted it into the white USB socket of the mainboard and pressed the BIOS_FLBK button. The LED flashed 4-5 times and then became steady green which means it didn't work. What would be the next step?

What are the last 4 digits on a sticker like http://www.guru3d.com/miraserver/images/2011/990fx-sabertooth/IMG_4499.jpg ?

Just to clarify a few things.
The FX -4100 cpu has been used in another board by yourself and you know it works yes?
And the Asus M5A87 Evo 2.0 board also works as far as you know.

Or did you buy both from e-bay or something, on bidding on them ?
Or where you given them from a friend, and know they were both working right, the FX-4100 cpu and the Asus motherboard.

Because the board as it stands with being a revision 2.0 should already support the FX-4100 cpu without any sort of bios update at all needed.

A red cpu light lit solid , is a good indicator that the actual cpu is damaged internally due to excessive overclocking and high voltages applied to it.

Ot it means you should remove the cooler and check the underside of the cpu it`s self for any missing or bent gold pins.
Due to improper orientation of the cpu in the cpu socket of the motherboard.

So I would check that. The red solid lit light as said means the cpu may be broken or power is not getting to it correctly due to a missing or bent cpu pin on the underside of the cpu.

If you find a bent cpu pin simply use a craft knife blade to roughly straighten the cpu pin that may be bent.
Being careful on how much force or pressure used.

Make sure that when placing the cpu in the cpu socket of the motherboard it is in the right orientation.
The gold triangle on the cpu should be lined up with the white triangle mark on one corner of the motherboard jut bellow the cpu socket.

Before you lock the retention arm down of the cpu in the socket make sure that all four edges of the cpu are laid flush when st in the cpu socket. Then lock the retention arm on the socket.

Then CPU is supported, No need to flash the BIOS.
You mentioned "No beep"
Is a case speaker http://images17.newegg.com/is/image/newegg/12-201-032-TS?$S300W$ connected to the motherboard?
If yes, try starting the board without RAMs installed.See if the CPU fan does spin and if any beeps.
If no beeps, then either motherboard, or CPU does not work.

Shaun o :

The mobo and CPU were purchased separately on eBay. I have just removed the CPU and checked it, it looks good with no bent pins and it's correctly oriented. I have to get a case speaker tomorrow. In any case, even if the CPU is faulty the flashing of the BIOS would work anyway, wouldn't it? It takes place within the mobo and CPU has nothing to do with it, right? Perhaps I could go and get the CPU checked.

alexoiu :

As I understand, I should be able to flash the BIOS without having a CPU installed. If the flashing does not work isn't that an indication that the mobo is at fault and not the CPU?

alexoiu · Dec 22, 2015

It could be an indicator, but not a "100%" one.

I rechecked the CPU once more and found the problem, the CPU was seated OK but not locked in place. Now everything works OK but when I enter the BIOS program I see that the SSD disk on SATA port #1 is not there. It is a new SanDisk Z400, unformatted. Do I have to do anything with it before installing it?

Is SATA set to AHCI ?

hcccs · Dec 29, 2015

CountMike :

Yes. I have an extra PCI card with three extra SATA ports which I don't see in BIOS. The DVD works off one of them and it works. I moved the SSD to one of these ports but I still can't see it in BIOS. The SSD disk is a 2.5" in an adapter. I have checked the connectors and it looks OK.

SOLVED!
The disk connector was not seated properly in the ICY DOCK adapter. Now it is and now I can see the disk in BIOS.
