Hi Folks,

Anyone know what the MAX temp for the above CPU is? I've had one such die on me recently and it was now and then running at 48-50C..

That's water cooled temps:-/ Using a Corsair Hydro 100..with 4 fans in push/pull

Now I find that with a new FX9370 CPU temps are running at 37C.. on my old CPU temps were stable at 34C running 4 GPU tasks plus 2 CPU ones. OLD CPU was a FX6350

AMD don't seem to publish max temps for CPU's these days, or the info is hidden somewhere on their site:-/ All I can find is wattage..

61C max for FX 9370. I have 2 of those as well and the Corsair Hydro but only doing a push config. I've never had it go over 40C.


Happy Crunching...

Hi Zalster,

Thanks for the info.

I'm thinking maybe my cooling was off somehow, anyway I've reinstalled the waterblock and temps are higher than with my old fx8350 but def under 61C core and Tprobe CPU, so I'm hoping the last FX9370 croaking was just a case of bad chip failing under pressure..

Anyway I'm keeping a beady eye on the darn thing..

I think a video converting program I use may have maxed the cpu out, it runs all cores at 100%...

That's kind of disappointing that the product details page for the 9370 doesn't have a lot of the values filled-in.

I would have guessed modern CPUs would be able to tolerate ~60C.. I know the days of 105C being the max die temp are long-since over, and modern CPUs are supposed to downclock and shut cores off when they get above a threshold to prevent damage.

Even since the 2002-era, I've always just gone with the general rule of thumb of "keep it under 60 and you'll be fine."

Linux laptop:
record uptime: 1511d 20h 19m (ended due to the power brick giving-up)

Cliff it was probably a bad chip my FX has been at 64 for hours and still works but it doesn't like it . Going over about 58 can case errors or stuff the PSU . I'm afraid to say unlike intel the AMD FX chips are wanting in the area of working in temperature . I have had to slow the chip to 3 gig to keep temps controllable at 4 gig it's just won't keep cool if you work it .
I'm afraid my next chip wont be a AMD one , i'm going back to intel less freaking trouble

Hi Glen,

Its running at 35C right now under roughly full load..

I switched off turbo mode in bios, damned mobo doesn't seem to give access to underclocking, its stuck on auto for CPU freq & speed:-(

Wont be gong the Intel route tho.. Need to buy a new Mobo as well as CPU and its not going to happen given existing prices for comparable kit.

Hi C_O,

Yeah, that AMD page doesn't even show the existence of BE chips, but mine has BE on the box.. 16MB cache etc..

Seems temps [core] under 60C are OK, so I'll keep on watching its temps

Cliff are you shore that chip is UNLOCKED you won't be able to change the speeds if it's locked

I have the 8350 4 gig UNLOCKED chip so it mite not be the mobo my mobo is a Gigabyte 970A-D3p mobo but if i was you and are going to buy a new mobo get a 980 or 880 board (980 Gigabyte 880 Asus) so long as it has the 8+2 power design and not the 4+1 .

The 970 has the 4+1 ,I believe this design may have stuffed your chip like it keeps stuffing my Psu's if that's the type of mobo you have . Draws to much power through the 4+1 power design when you use more than 4 cores at one time. (but still experimenting so i could be wrong )

The 980 has the 8+2

Hi Glen,
Yup the chip is a BE one, its the motherboard bleeding bios that's posing the problem.
But I've cut core usage by another non seti project to 1 core and that took temps back to 36C:-)

Actually all Black Edition CPU's (BE) are unlocked, but you very likely have to change a CPU setting in the BIOS from Auto to Manual (or something similar, check your motherboard manual for more info) to access those settings so that you can change them. ;-)

Cheers.

Check in bios for CPU load line calibration.
Not all mobos offering this setting.
Increase it to 50-60%.

Hi Wiggo,

Its an Asus Sabertooth R2.0, and the bios is complex:-( Its designed to overclock the rig not underclock it..

I don't have the ability to change the cpu multiplier from auto to anthing else, its greyed out unless on chooses an overclock option:-(

Methinks there is probably something hidden under layers of tweaks that allows it, but I'm not about to fiddle with multiple setting in order to down the speed. As it stands I've disabled turbo mode for the cpu and that seems to be working ok.

Hi Mike,

What does increasing the load line calibration do? There's probably an option in the bios, seem to recall seeing it under the cpu or northbridge settings page of the bios.

I miss the good old days of more than 1 bios supplier:-( It used to be sooo easy to alter the multiplier on an amd cpu, even if one had to use a bit of subterfuge on the actual chip links 1st.

And get updated and modded bios's from web sites..

Since i have the same motherboard i can tell you you really want to do that.
It handles the load of those threads much better.

Btw i have undervolted my 8350.
But that requires lots of testing to get it stable but i have very nice temps, air cooled.

Hi Mike,
Been doing a bit of tweaking:-)

Changed CPU/NB freq from 2200 to 2000

plus a few other items that were disabled under optimised settings I've re-enabled and now my temps are running at 32C Tprobe and cores at 19-24C

That's under load, but without the additional CPU core re-allowed.. I'll try that again later on.

Glad you are able to optimise the 8350, mine ran ok without any overdue rises in temp running at std VGE's, its just the 9370 that's been the problem:-/
[edit]
Just re-enabled 1 more core, temps seem stable at 35C tprobe and about 19.1-27C core.

Cliff, I also use the Sabertooth R2.0 motherboards. Yes, you can underclock the CPU very easily in the BIOS. You can set the Load Line calibration for the CPU and Northbridge chipset also very easily. The settings are in Advanced Mode under the AI Tweaker tab. You need to select the CPU Ratio setting and move it off Auto. The Auto value changes to the default xX ratio and from there simply using the +/- keys will change the ratio up or down in 0.5 increments. You can underclock your chip from there if you need. You can also alter the FSB frequency from the stock 200 MHz. This is another way to overclock/underclock your unlocked chip. I would recommend disabling Turbo Speed, Cool 'N Quiet, SVM and C1E.

The Load Line Calibration settings are again under the AI Tweaker tab, another page down from the main first page under the Digi+ Power Control setting. You can move off Auto and bump the LLC up to Medium or High for both the CPU and chipset. You can also increase the current settings for both to 130% to gain greater overclockability. I would recommend looking at this URL link for all things pertaining to overclocking the Sabertooth motherboard:

http://www.overclock.net/t/1348623/amd-bulldozer-and-piledriver-overclocking-guide-asus-motherboard

The Sabertooth BIOS is actually really easy to use and gives you many choices for achieving stability at whatever clock speed you desire. You just have to make changes, test at load and retest. Look over the overclocking guide to get the idea and then go at it.

Cheers, Keith

Hi Keith,

Thanks for the info and link, will follow up on both later.

Well this has got to take the bleeding biscuit:-(
Had another sudden shutdown, replacement CPU suddenly had escalated temps, under moderate load.

This was a brand new CPU, from Amazon delivered to replace the one that had failed and was taking a long time to get replaced under RMA.

Don't know what the score is with these 9370 CPU's that's the 2nd one to go pop for no apparent reason.

I now have the CPU that was sent under RMA to replace the 1st one to go pop.

On past experience after about 8 days this blighter will probably go toes up as well.

So another RMA situation this time with Amazon, who have just failed to deliver a new sabertooth motherboard on the promised date..

I've stopped all direct CPU tasks and am just running GPU ones from here on in the hope this CPU will last longer than the other 2.

I'm now wondering if in fact its the mobo power regulation that might be causing problems.. clutching at straws I guess:-/

Anyway as soon as I can afford it, I'm going to revert back to an 8350 CPU and the devil with the 9370's.

Contacted Amazon and organised to RMA the dratted FX9370 CPU, for a refund..

Cant post it back until Monday, but with luck a week from then I'll have the refund and be able to order an FX8350 CPU.. That model always seemed to cope with everything I chucked at it:-)

Like the Phenom 2 series the FX chips work best under the 990 chipset.
I have tries the older chipsets and and different power phases but the best by far is the 990.

I have the Gigabyte 990FXA UD3 Version 4 mow and stable at 4 GHz with core voltage 1.5.
Stay away from boards that have 4+1 power phase and go with 8+2

The Phenom 2 1100T now is purring at 100% load and 40C temp.
I use a coolmaster 212 Plus push and side plate off the box.
Small deskfan to cool the Mobo.

I have got this up to 4.4 and then needs more voltage.

I have seen Phenom 2 at 1.55 but that is a bit scary temps
