Possible burned down AMD FX9590, require help from more experienced people.

Twilight Remedy · May 9, 2017

Good time of day. I could really use some help from professionals.

I had a motherboard ASrock 990fx extreme9, which, unfortunately, has burned down. I'll provide an image of the scorched spot. My question is..... how possible is it that my CPU has also died alongside with it??

I tested my PSU's voltage outputs on all it's pins for both ATX cables, everything was within the ranges. So, it should not affected by the motherboard's death.

I tried everything i could to test it on a new motherboard i got (MSI 990fxa), i usually refer to these forums whenever i have a trouble with my PC, but this time i could not find anything.

My ASRock 990fx Extreme9 is burned down.

My MSI 990fxa doesn't provide any beeps, with AND without RAM/GPU. CPU however does heat up.

I also do have GIGABYTE GA-970A-UD3P, but it doesn't provide any beeps or any other information i could use too.

With the last motherboard mentioned, can i use it anyhow in any way to check my CPU?? Or is it completely dead and i should look for another one??

I'm asking you guys, because i don't know which problem it might be. Dead CPU or faulty MSI 990fxa, since the GIGABYTE card i have is not compatible with fx9590 from what i know.

Thank you in advance for the help and answers.

If testing with another PSU doesn't work (it doesn't have to be very powerful), I suggest you RMA the CPU. It may have been damaged when the VRM burned. Did you apply too much voltage to make it stable? How were you cooling the VRM?

GhislainG :

Good day, GhislainG, thank you for response!!

I have a custom liquid cooling thing. Nothing from the market i tried before could tame this processor. My computer would just freeze from overheating.

Thing is..... i downclocked this CPU. Like i said i was struggling big times with cooling it down. Even if i did something ~ it was to reduce the voltage. I suppose that VRM you are talking about has something to do with Voltage Regulation thing? (these abbreviation, i'm sorry)

It was cooled by the stock heat sinks that ASRock provides with them. Do you think it burned down because of overheating? These heat sinks were indeed hot, like... VERY HOT.

I have several other PSUs lying around, but none of them are 24~pin ones.

And about RMA part.... it's about returning the goods, right? I'm not sure if i can do it. I've had this CPU for over 4 years now, i think. AMD does promise to return CPUs that died from overclocking though..... maybe downclocking was the issue that cause it's death.

GhislainG · May 9, 2017

ASRock recommends to improve cooling when using a 220W CPU; that can be done by adding a fan to cool it. A 20-pin PSU is fine for a simple test; you only need to check if it will POST. Use a low power GPU that doesn't need additional power from the PSU.

Downclocking didn't cause the death of the CPU; however the VRM component that blew may have damaged it. If the CPU has to be replaced and it no longer is under warranty, then you should either consider an upgrade (new motherboard, CPU and memory) or buy an FX-8350 that will be almost as as fast as your underclocked FX-9590 and it won't cause VRM failures.

dear god just throw that thing into the thrash.

GhislainG :

I inspected all my old Power Supplies. None of them has got 8 pins for the processor feed. Only 4 pins connectors. One of them has 20~pin connector for motherboard and an attachment to make it 24~pin connector.

In summary..... no 8~pins to feed the CPU. Only 4~pins everywhere.

Can you use 4 pins to power CPU instead of 8 pins?? I know you can do that for 24~pin socket.

GhislainG · May 9, 2017

To POST, 4-pin CPU power is enough.

Twilight Remedy · May 9, 2017

GhislainG :

Tried with my 300W Power Supply on GIGABYTE GA-970A-UD3P. No response whatsoever, the processor does heat up again though.....

I guess my AMD died then, eh? Both GIGABYTE and MSI can't possibly be faulty, right?? Motherboards won't provide beeping sounds without a CPU installed. I tried everything i could too, with your suggestions now, GhislainG.

GhislainG · May 9, 2017

You could have it tested by a shop, but if it still is under warranty (2 or 3 years according to http://support.amd.com/en-us/search/faq/137), then RMA it.

Twilight Remedy · May 9, 2017

GhislainG :

I only have this processor. Nothing else. No box, no nothing. Just some transparent plastic cover above it that came alongside with it when i bought it. Don't suppose they'll look deeper into this chip without any other items like box and instructions and whatnot?

I guess i'll pick a lower tier processor, fx 8370 looks suitable for me........ what a huge disappointment and waste of time and money that AMD 9590 was..... honestly...

Thank you very much for the assistance, GhislainG.

The GA 970A UD3P doesn't support the FX9590 in bios, so it'll not register as a working cpu. Very few mobo's will actually have support for either of those 9 series FX.
While you might not agree entirely with superninja12's assessment, he's honestly not far wrong either, those 9 series cpus have been nothing but a headache for most users as heat outputs and necessary cooling mostly far exceed the general wattage output of a decent OC. You are starting out with a 220+w cpu vrs the 77-125w of a i7/FX8 which stock isn't that much worse, if not better in performance.
So, you have 2 options basically. Start from scratch with a new mobo/cpu and possibly ram, or try and save your build. Saving it will entail having a shop correctly test the cpu with a known working psu capable (300w really doesn't cut it) on a known working board capable of supporting the cpu itself. This could get expensive. Or replace the mobo with another (maybe an rma from ASRock) or other such older gen board, and hope that VRM's burnout didn't actually fry not only the cpu but the ram too. Rma's may or may not apply since the issue was not related to defects of the cpu/ram, but from a 3rd party mobo, so technically it's not a manufacturer defect, you'd might have to argue with ASRock over replacement since it was their board failure that caused any/all collateral damage. Basically, this whole thing could get both ugly and expensive, not to mention time consuming with all the back and forth emails etc, so that too must be weighed into the decision. Or just do as superninja12 suggested, toss the whole thing in the bin and start over.

The OP already bought a MSI 990fxa and it won't POST with the FX-9590.

Looks like fried VRM, of course Asrock want you to add more cooling they have to nannycode their VRM chips to thtrottle even with APM off. Im suprised that even burned up with the fail safe nanny. Last thing I saw burn was a flimsy early revision of a UD3 it was like the 4th of july!! But with nannythrottling? Wow dude what did you do?

Anyways I wouldnt worry about CPU. Should still boot up, you dont have another board to try it out?

GhislainG · May 9, 2017

May I suggest you read the first post?

SOrry, I see 2 other boards no POST? Hmm

GhislainG · May 9, 2017

Since both motherboards should POST with that CPU, we have to presume the CPU is defective.

mjslakeridge · May 9, 2017

Cut your losses. Get rid of the CPU. Go with a 8370.

Twilight Remedy · May 9, 2017

Good time of day Karadjgne, GhislainG (again!), 0ldsch00l and mjslakeridge. Thank you for responses and assistance!!

@Karadjgne, yes! Yes i know it doesn't support it, but i do recall it launching into BIOS with 9590 on board..... at least... at least i think i do. It's been so long......

Anyways... i'll take one of the options you have mentioned. Both, in fact. Since i already got another motherboard.... I'll try to get a working CPU (preferably 8370), or try and figure if this is actually working. Somehow. (yeah, i guess i still got my hopes way high up.... for no reason i think)

I wrote a letter to ASrock, hopefully they'll help me ID the problem, find the right component.... and, perhaps, i could solder it, or try to at least.

There's no way i'm giving up on this chip so easily, this 9590 was suuuuuuch a pain in the ass.... NUISANCE honestly!!!! So much lost in time, money, nerves...... aaargh..

@GhislainG, OP? What does OP mean?? And yeah, no POST signals on both new MSI and my old GIGABYTE boards with this AMD processor....

@0ldsch00l, it is indeed a burnt part of a VRM, as GhislainG guessed before. And yeah, chances that this AMD is dead are.... not at all in my favor unfortunately. And both MSI and GIGABYTE boards do not show any signs of life in them with that CPU.

@mjslakeridge, yup, i'm going exactly for this one you suggested.

GhislainG · May 9, 2017

OP = Original Poster (you).

Twilight Remedy · May 9, 2017

GhislainG :

Ah thank you! I did not know that.

Karadjgne · May 10, 2017

The ASRock board is toast. Apart from the VRM component you can actually see, there's the copper/gold traces underneath that are integral to the function of the VRM's as a whole that would by necessity be replaced, which is beyond the scope of just about most ppl as it takes specialized tools to correctly deal with such thin conduit. I've never been able to solder traces right, they just don't take to it, even using 15w irons and thin guage silver solder. Sorry, but that's one part you can absolutely consider a write off. Hopefully you have a good outcome from ASRock, the Extreme 9 isn't one of their cheap production boards.

The 8370 is arguably the best FX cpu made, some prefer the 8350, but I'm thinking that was purely from a budgetary point of view.

Good luck with this.

Hi Pete,

I have 2 Asrock 990 extreme 6 rigs up and running with 9590's in them and all the appropriate cooling. Stable at 5.0 GHZ i'm very happy with the 9590. Took awhile to get the cooling right and these ASROCK mobo's are questionable the heat sinks on the board get real hot. need lots of case airflow.

I can test your chip out as i'm about to change the cooler on one of them it would be a simple drop in and test moment for me.

If you haven't solved your problem i'm in AZ ...USA. I would help via mailing it back and forth if you want.

Wendell
