AMD CPU 9590 Black Ed - Help with compatible motherboards

switcheHHH · 3 Mar 2015 at 11:59

Hello all,

(I put this post here as I want people with this CPU to hopefully see this and give me some advice)

This thread might be a little long but I hope to explain myself clearly enough.

So I recently purchased this CPU:
https://www.overclockers.co.uk/showproduct.php?prodid=CP-360-AM&tool=3

I purchased this motherboard with it:
https://www.overclockers.co.uk/showproduct.php?prodid=MB-560-AS

So the first mistake I made was purchasing a motherboard that doesn't support - TDP: 220W. The one I purchased supports 140W TDP I believe?

So now my next question is, how the hell do I tell what the TDP limit is on a motherboard? Would it be this? (see below picture), if so then I don't know what motherboard would be suitable....

I have been told that this following board would be suitable
http://www.overclockers.co.uk/showproduct.php?prodid=MB-576-AS&tool=3

However it says 'supports CPU up to 140w'. If that is the TDP then this would be incorrect and people are feeding me incorrect information.

So basically I am getting frustrated with it all, I do not want to make the same mistake twice. So please can someone clarify where I can find the TDP for each motherboard, and maybe recommend some boards that will actually support this CPU.

Thanks in advance for your time guys.

the Asus M5A99X PRO R2.0 officially supports the 9590 anyway. It's just OCUK's info page which is wrong.

See the support list;

I think you posted on my other thread.

Thanks for the link, I see it's listed.

''Due to the high TDP, please be noted there are limitations while using this CPU(i.e. special thermal required..)''

We established my cooler was working fine, so is my cooler just not good enough for this CPU?

Let's not get confused between power consumption and tdp.

Originally back in 2013 the fx9370 and 9590 were oem only.and came bundled with a h80 type cooler.

The 220w tdp of fx9590 is based on a worse case scenario of cpb enabled and a high vid over 1.55v, with this amd are stating.you would need a cooler capable for transferring the heat at this voltage.
The truth is all the fx 9370 9590's vary on their vid. So whilst some could come with 1.43v
Others could even peak at 1.55v or more. So that 220w tdp could be classed as worse case, with it being much lower on average, or with undervolting the cpu by the user.

As we ran that p-state tester we saw your fx95 uses 1.47, from my experience I can say thats a good average voltage for a fx9590 and with cpb on that would probably increase to 1.5v.
Your board should be capable of holding 1.5v on all cores, with vrm cooling it should just about hold 1.55v. But from testing we struggled with package temps at.4ghz using 1.35v.
We still aren't sure what is causing your issue

Boards that support fx9590
Are your current board, rev 4 gigabyte 990fxa ud3/5
Asus sabertooth r2.0, asrock extreme 9, asus crosshair

Roughly translated means throttling in certain situations to protect the motherboard, assuming the motherboard is stable to begin which from what I've seen is not guaranteed with these 220W TDP processors.

I wouldn't blame motherboard manufacturers, they've been dealt a crummy hand by AMD shipping 220W TDP processors which pull way too much power (they are just insanely overclocked & overvolted FX8350's). I wouldn't even try to overclock an FX8350 to 5ghz on 1.5V unless I had a top end motherboard, certainly not for long term use anyway.

There was a link posted near the end of your graphics thread which showed a list of compatible motherboards and overclocking the 9590.

Personally I would concentrate on Gigabyte or ASUS only. Look for DIGI VRM, a good heatsink in that area and 8+2 phases.

I have gone back to air cooling on my crosshair V formula (non Z) which does not officially support the 9590. The Z version does. So I have bolted the standard heatsink back on (literally with M3 x 25mm set bolts and nuts). I get good results from this and a silverstone heligon HE01 heatsink.

I have three 120mm exhaust fans near to the VRM area, two top and one rear, which provide decent air flow and prevent heat build up.

Will be selling my VRM watercooling block but I am permabanned from the MM so it will be elsewhere

good luck, andy.

Just got the following email back from OCUK

''The 9590, at the moment, can only go in to the Asus Crosshair V formula Z or the Gigabyte 990FXA-UD7/UD5/UD3 (latest revisions of the UD5 and 3 are available on our website).
The Sabertooth will also take that CPU, although it does not officially say that it can take 220W CPUs.

Please be advised, though, that using the 9370 or 9590 chips requires the use of a top-end air cooler such as the Noctua d14/15 or the Thermalright Silver Arrow or a closed loop watercooler such as the h80i or h100i (240mm radiator) if the case allows for it.''

I think we can say though my board ''supports'' the 9590 it isnt really meant for it...

switcheHHH · 3 Mar 2015 at 14:32

I have gone with the above Sabertooth board.

Thanks again for the feedback, appreciate it.

Sorry, but I can't agree with that. Many people have and recommend that board for OCing the 83** series and many run more than the 1.47 vcore your 9590 chip required, you also still had the problem running the vcore at 1.4 and less. This rules out TDP and makes it a red herring. I don't believe you made a mistake, IMO you had a faulty board or its still the CPU (which hopefully you will find out pretty quick with the new board). Remember it is an officially supported chip, so even worst case scenario, it should be able to hold the chip at standard clock and certainly shouldn't have been exhibiting the issues you were finding. Not your fault so I hope they are not charging you for the return.

Anyway, I'm sure you will like the sabertooth and hopefully we can help get you up an running when it arrives.

I have 3 days to call an RMA on this board or CPU... So yeah hopefully I can work out what is what tomorrow.

They WILL be getting something back, as I am not paying for stuff that is faulty >___>. First and hopefully last time I have this crap happen lol

gpuerrilla · 3 Mar 2015 at 21:41

You have a cooling off period after sale, you can always add to the faulty aspect by stating it is not fit for purpose with the CPU you ordered. Did you order the sabertooth from the same outfit?

Everything is from OCUK.

What I would try, return both for refund on the basis they are not fit for purpose according to their own support (You purchased them together on the basis they work together so it a valid reason for returning both). Then swap them for 8320E with sabertooth or better and hopefully save some money in the process. It may also save some time from not having to return and diag the cpu if the problem persists with the new board. But again, this is just my opinion on the matter.

I understand your frustration.

If the problem persists on the new board then the first board and the CPU are going back. I will then keep the Sabertooth and get a diff CPU sent back.

Will see how tomorrow turns out and will let you all know.

Whilst it is under the sale of goods act (or whatever the online consumer right may be), I would save yourself a headache and do what scurburg suggests which is return the original motherboard to OcUk. Explain to them the issue and that you have already purchased the Sabertooth with them as it is best suited and will cause you no issues. Obtain a refund for that and learn from the mistake.

But I tried to return once and they said no as it was past 14 days. So I don't think I can do that...

If it isn't long after 14 days then have a word with Gibbo, he may be able to swing it for you (as you'll be buying the replacement from OcUK too).

Pop a post in the Customer Service section for his attention and explain your problem and maybe link him to this post. Worth a shot tbh, he's a great guy when it comes to customers of OcUK :cool:

Thank you for the advise, I will first test out the new motherboard and see what results I get. The parts will get to my mates house by 1-2pm, I will get to his for 6pm after work. Then I will address making a post on customer service once I've tested everything, thanks.

switcheHHH · 5 Mar 2015 at 02:09

Well it looks like it was the motherboard after all. Today is the 28th day so i will issue an RMA for a full refund, it's the same cooler I was using before hand so I can safety say the cooler works fine.

The new Sabertooth is perfect, no issues at all and here is a little picture of the temps after a 5 minute stress test that I would crash on within seconds before.

Great news. Just get a couple of small fans over the VRMs and you should be golden.
