Hello, as the title suggests. I done a bit of homework, clearly wasn't enough. Purchased a MSI 990fxa Gaming motherboard and the AMD fx9590 cpu. the system works fine until there is substantial load on the cpu and the temps climb to over 50c this is when the system locks up.

It plays games fine with an average temp of 35c-45c

it only seems to have a load when downloading things especially when doing game updates on steam.

Full system specs are

MB: MSI 990FXA Gaming Bios v.1.4
CPU: AMD FX9590
RAM: Team Group Elite Black 16GB (2x8GB) DDR3 PC3-12800C11 1600MHz Dual Channel Kit
PSU: Cougar STX 650W 80 Plus
GPU: MSI Geforce GTX 750ti
HDD: Kingston 120gb SSD


I was on a budget for this build with aspirations of upgrading the Gfx card at a later date once I had saved more money, The reason I got the 9590 was it was on sale at the time and was cheaper than the 8350.

When I first built the system it would freeze almost instantly, I found some Bios tweaks on here.
C1E support is disabled
core 6 state is disabled
amd cool&quiet is enabled
These settings made the system more stable but when the temp increases to 50c it is pretty much guaranteed to freeze.

I am asking if this is a bios tweak that could fix the problem or do I need better cooling?
I am currently using a Raijintek Themis cpu cooler I feel this might be inadequate.

I apologise if there is already a solution to this problem on here, I spent a good couple of hours looking but couldnt find any solid solutions.

Any help would be greatly appreciated.

Regards

Jay

'' My experience is buying an 8320, overclocking it to 5Ghz and having a CPU as powerful as a 750$ Intel 5390k for 125$ 😉

never happen

going intel opened my eyes night and day your sadly mistaken on amd doing better , sadly amd don't have near the processing power with intel you get what you pay for 'processing power''

and I'm not saying my AMD builds prior to AM3+ were disappointing heck my old 939 was a better platform then AM3+ , that's how sad it was

what takes a AM3+ chip overclocked all you want does a calculation in 22 sec this i5 non k box stock does it in 9

for example , like here you got to go a long way down the list [past a lot of older intel chips ] before amd shows up why aint they up...
Just as you said, you need better cooling. There is NO way that the Raijintek Themis can handle that processor, it's meant to be used with 120W or lower CPU's. That's a 220W part, almost double of what it's supposed to work with. It's not even common for someone to have that CPU with air cooling, most people use water pumps, and even then, not the cheapest models are enough.
 


Thank you for the rapid reply, I had thought the cooler might not be enough. I didnt do enough research clearly. what cooler would you recommend?
I have heard that the noctua NH-D14 is one of the best but I understand that watercooling is the preferred method, I am wary of water cooling but if it is recommended, what water cooler would you recommend?
 
well if you look at those 220w chips just here at toms that's life with them

http://www.tomshardware.com/forum/all.html?refine=fx+9590+freezing

thing is with that msi you don't really know if its a true 220w board ?

http://www.tomshardware.com/answers/id-3054845/9590-evga-gtx-970-hard-freezing-issues.html

them chips are novelty cpu's and what AMD was thinking with them is beyond me to start with


Due to the high TDP, please be noted there are limitations while using those CPU🙁i.e. special thermal required..
FX-9370(FD9370FHW8KHK, 4.4GHz, 8C, L3:8M, 220W,rev.C0,AM3+)
FX-9590(FD9590FHW8KHK, 4.7GHz, 8C, L3:8M, 220W,rev.C0,AM3+)

that may help but if the board cant feed that 220w ?????
 


Thank you for the reply. I have read most of that information. I didn't see the MSI link until now, the cooling is not sufficient I gather?

 
If the onlyvreason you bought the 9590 is because it was cheap then down clock & undervolt it

Re-enable c1 & c6 ,- they have nothing to do with clock speeds

Turn turbo core off
Set multiplier to 21.5 (4.3ghz)
Set manual voltage to around 1.4v

The themis will handle that speed & voltage.
 
''that mobo is the problem , that temp they are referring to is the vrm " that's the power phase which supplies power to the cpu ", I have several friends who use that mobo and for just a 8350 they add fans to the vrm to keep them from getting to hot and dropping vcore.
those mobos with so called 9xxx series support block out the oc features as they really cant supply power at the factory clocks

sad thing is like asus take a 120w speced board but give 220w chip support in its bios/ compatible list and then a guy buys all that lie and here he is at toms with it

its hard enugh to get a 120w chip like a 8320 to run hard and stable as it is at times now you go 220w ??? like I said I don't get what AMD was thinking on all this I guess wows folks with that 220w and makes sales ??

lots of cooling and lots of bios work to find what works out I guess
 


When I go into the BIOS, Turbo selection is greyed out. I don't like fiddling with the bios unles I either know exactly what I'm doing or I have clear cut instructions.

Any chance you know how to access the turbo core selection?

Thanks
 
You're not overheating. I agree with matt. Sounds like the classic Turbo core issue that affects the 9xxx series. Disable it and set an appropriate clock speed.

You don't need liquid cooling if you're not going heavy on the overclocking. Air cooling is good for the FX series as it cools the VRM's. When you're at 220watt TDP you most definitely want airflow over the VRM's. Please use a separate fan or orientate your air cooler so it blows over them and exhausts out of your case.
 
Enter bios , click big oc tab centre left.

Adjust CPU ratio - change from auto to 21.5
Adjust turbo core frequency naybbe greyed out but this isn't the option you want , 2 options above is amd turbo core technology - it will be on auto , change it to disabled.

4 steps from the bottom is CPU Voltage - change it from auto to 1.4v (this is a best guess as the 9590 is a high leakage chip , a good 8320/8350 will manage it at 1.36-1.38v sovsetting 1.4v should work OK)

Save & exit bios.

This is what I am greeted with, all the selections you mentioned are greyed out
 


I clicked it, a message popped up saying that oc genie does not support cpu over 200w
 


I am on the latest version for this motherboard. the msi site has no bios past v 1.4
 


Well, mistakes happen friend. Next time research, research and more research before pulling the trigger.

 
Well mate straight from an MSI rep offvtheir official forum s (there are many many unhappy customers in the same boat) the oc options are locked to stop you tampering & burning out the board and/or CPU.
That really is a shambolic joke IMO, as someone asked just like you why they cant underclock because their system is totally unstable.
If it was possible to throw a blank look over the internet as if to say 'we didn't think of that' that's what the guy got in response
your only option is fsb down clocking to 180 , & then upping yourcram speed back to 1680mhz.

Will that be stable enough ?? I don't know in all honesty, it depends if the board drops voltage enough automatically.
The fact you cant even disable turbo core which pushes over 1.5v is an absolute joke, I'd personally RMA the board as unfit for purpose.
 


You did not waste anyone's time. We learned that that motherboard does not fully support those CPU's properly. When others ask in the future we will know the issue. Not a waste.

And I agree, I would complain to MSI about this. Half-supporting a CPU is a joke.



 
The FSB will only go down to 190
the dram speed will only set to 1600 or 1866. I didn't want to fry the ram so left it at 1600 which drops it down to 1520 with the fsb at 190.

would it be okay to oc the ram to 1866?
