Problem with plaque?

[Kernel1.0]

I never had any compatibility issues between a motherboard and some memory, and it didn't beep at all

[ferelxyx]

that may be the memory, try a single one in several different banks or other memories

today I will try with a micro 8350fx to rule out problems
if it doesn't get solved I will have to try other memos
G skill?
greetings and thanks

It could be solved or not…. GSkill are good because they use Samsung chips but make sure they are valid for 990FX... if the XMP profile is optimized for Intel you will have problems with the secondary timings... which is where the incompatibility problem arises since if you use the standard JEDEC there should be no problem... except in this case. Anyway, as soon as you plug in the FX you will know. I would go for some Crucial... well in fact I have some Crucial and they are a rock... in fact all the home computers have Crucial memos and zero problems. If you want to check the compatible models for yours this is your link… you can get them directly from them or search for the reference on Amazon... otherwise Alternate I think also has crucial.

[Clipper]

well I hope they work, because if not the first candidates in g skill were these and it seems that they are not 100% compatible with the amd series 8

well I didn't have time last night
but I think I'll be lucky

Well, grab all a song and hit yourselves on the feet at the same time as I.
It wasn't F.A.'s fault.
It wasn't the micro's fault.
It wasn't the memory's fault.
It wasn't the motherboard's fault.
If you connect everything and press the power button and the fans don't turn...
What could it be?
I'll give a Sugus to whoever figures it out.
;D

Did you connect the POWER and RESET switch connectors incorrectly and that's why it wouldn't start?

[Sylver]

The 24-pin molex from the power supply connected backwards on the motherboard.

My first rookie mistake in this little world… I will never forget it

Regards

[Clipper]

You are without sugus, so you should know it
:frio:

[whoololon]

I found Sylver's story funny because the same thing happened to me.
My case was when the AT format was around. That Gigabyte was tough, I still have it.

Did you connect the 8-pin ATX?

[Clipper]

Come on… A little imagination;D
Best regards
P.D it's something very silly....

[whoololon]

Damn, well the most embarrassing thing I can think of is this:

[Sylver]

What whoololon says, or the power strip turned off, or the motherboard's molex disconnected, or the BIOS jumper set to CLEAR, or the micro left on the table without being put in xDDDD

Edit: AH, the power supply switch, a classic…

how were you able to connect the 24-pin molex backwards and not fry anything? =-O

[ferelxyx]

you don't mention the graphic, so you didn't put it in,

[Sylver]

@Kernel1.0:

¿how could you connect the 24-pin molex the other way around and without damaging anything? =-O

In fact it was the old one, the 20-pin one, and they fit perfectly in both positions, you have to look at the anchoring tab

And at the level of operation nothing breaks because the cables that allow the flow of current do not coincide, so it does not start or anything :sisi:

¡Greetings!

[Clipper]

Hello
Both the cables and the connectors were properly placed as well as all the components.
My first mistake was to assemble the entire equipment inside the tower (when it's a new motherboard I always test it on the table)
You still don't have sugus
Regards
P.d what a beast …. Putting the 24-pin molex in the wrong way

[Sylver]

Now that I think about it, under normal conditions a 20-pin molex doesn't fit the other way around, I suspected the 24-pin one wouldn't, but I fitted the 20-pin one without forcing it into a board from an old Pentium II, I don't know if it was because the molex from that power supply was special and fit perfectly in both positions or because they used to be made differently, but I'll never forget that it fit the other way around without problems and it wouldn't start up, I went crazy until I noticed the little tab. A mystery about that old board...

Getting back to the mystery of now, I think I've interpreted your initial clue correctly... The fans weren't spinning because they weren't connected, right?

If that's not it, it could be that you didn't have the power cable plugged into the power supply, that the house wiring had gone bad, that you hadn't connected the power button to the board (derived from what espinete was saying), that you hadn't even put the power supply in (a major oversight xDDD)...

Regards

[Clipper]

The mistake was that I never installed the new motherboards in the tower, so I ripped them out with a flathead screwdriver making a bridge
But this time I didn't ….
That's why I didn't notice that the power button was cracked :troll:
That's why the fans weren't spinning... Because the motherboard wouldn't start
