Overclocked FX-9590?

Correction:

My Liquid Temp is 27.8C (idle) - Using Chill Control
My Cores Temp fluctuates from 6.2C to about 12C (idle) - Using Overdrive

Those are some very chilly cores.

Impossibly cold even...

WOW! AMD´s new CLCs are actually capable of cooling under ambient temp!

Yes impossibly cold, maybe you could monitor temps with different software.

Yeah my FX-8350 reports that it idle at a mere 8C...impossible given that the ambient is 28C.

This is part of the conundrum with attempting to monitor and report the operating temperatures of piledriver-based CPUs.

We know the numbers are clearly wrong at idle, so how wrong are the numbers at full load?

With Intel CPU's it is easy to determine the error because you just ramp up the temperature until it throttles, then you know you hit TJmax (which is published for Intel CPUs) and you can calculate the offset yourself based on the known TJmax versus what your CPU is reporting its operating temperature at when it throttles.

With my FX-8350 it goes all the way from claiming it is at 8C at idle to reporting to me that it is operating at 83C under full load before the system simply crashes (no throttling whatsoever).

Is it really at 83C? Probably not, just as it probably really isn't at 8C at idle either.

So it is just a guessing game, one which we are hoping you can clear up for us

Since it seems that there isn't an official response to this, do we have any hypothesis? Have you seen anyone attempting to discover an unofficial offset, for instance?

No ideas Best I could come up with was to use a thermal meter and see how hot the stock HSF got:

This is at stock clocks and stock volts. CoreTemp reported the CPU was ~55°C, my IR gun reported the external surface of the fins on the HSF were 51°C.

To me this is not possible. A mere 4°C delta from the CPU's silicon to the external surface of the HSF fin is just not a reasonable outcome.

The CPU silicon ought to be much much hotter than just 55°C in order to drive a 51°C temperature on the HSF.

Sorry if this is somewhat unresponsive to the most recent post here, but I wanted to try to stay on-thread (sort of). I have followed the thread because it relates to my situation ... I have a new build ready to start overclocking: Win 7 Home Pro 64-bit, ASUS M5A99FX Pro R2.0 with latest BIOS update, FX 8350 liquid cooled with Cooler Master Seidon 240M, 16 GB Mushkin Extreme Redline RAM, Mushkin 480 GB SSD, Sapphire HD 7970 3 GB Vapor-X, Cooler Master Silent Pro M 850 Watt P/S all built in an NZXT Tempest 410 Elite case. I planned to O/C the CPU, HD 7970 and RAM, starting with the CPU. I am using MaxMem2, Hardware Monitor, SpeedFan and CPU-Z for monitoring and Prime95 and Heaven for stress testing and benchmarking. I easily got the FX8350 to 4.4 GHz while keeping the core temp around 36 degrees C. But, the CPU socket temp crawled up into the 72-73 degree C range! So, I stopped overclocking and tried, unsuccessfully to learn more about the implications of these high socket temps. I discovered many opinions on the various forums, but very little hard, scientific or physics-based information. Neither AMD or ASUS was very helpful in providing specific info because I was in the forbidden realm of overclocking! So, I need your expert guidance. How important are socket temps above 70 degrees when core temps are very low? How high can socket temps safely be if core temps are acceptable and what is the basis for your view? What are the implications of 70 degree plus socket temps (or higher) for other motherboard components? I'd appreciate any specific, scientific guidance from some of you wise wizards.

It's exactly this kind of crap temp reporting combined with AMD's bs marketing of OC OC OC which is why I had no qualms recommending the guy with the toasted 8350 (difft thread) RMA it.

So while intel has chips that can properly report their temps and also throttle down when they hit their limit without issue, AMD cannot do either. AMD also has the added bonus of not telling people what the threshold limits are. Imagine that. So you don't know how hot it is, you can't check for throttling, and you don't know how much leeway you have. EVER ?? **BUT** AMD markets their chips to OC OC OC when they know fully well that is a recipe for disaster.

Yeah, that seems dubious to me too.

Are there any reference points for what sort of delta T one typically sees between the silicon to the HSF fins?

Maybe a benchmarking w/ some CPU with known correct temp reporting behavior? :hmm:

 

[FlanK3r]

The aprox temperatures are Coretemp and +15 C. So if your chip has 80C in load=real is around 95 C. Usually the PC take down CPU clocks or blackscreen.

While I don't know for sure about the 8350's, I know in the past that AMD's CPUs generally had a +12° to +15°C offset (depending on the specific generation of CPU), when we used Coretemp for our temps. Knowing that, I would generally agree with this statement.

Anyone with ASUS motherboards, just use the Probe II application from ASUS AI Suite II. I have found it to be the most accurate for AMD temperature readings.

The CPU properly reports the temps, it is the software that is not calibrated correctly. Most application developers(coretemp etc) doesnt have the temperature and diode data needed to incorporate them in to their software and you get wrong/false readings from them.

Also, OCing without knowing the absolute limits of your CPU is not something that prevented anyone doing it before. You may not find the absolute highest frequency your CPU may be able to operate but you can safely OC if you stay within safe Voltage/frequency limits.

I have asked my self AMD for more technical specs of their CPUs the last couple of years and the latest information i have is that they are planning to do something about it. The only question is, when will the data be available.

 

[sberganini]

I may have gotten a meaningful answer from ASUS tech support. After submitting a formal tech support case on the ASUS website I spoke on the phone today with a technician in their Global Technical Support department. This information comes from an unnamed "overclocking specialist" within that department ... the ASUS motherboard socket can tolerate a temperature of 88-90 degrees C without thermal or electrical damage to any motherboard components. The board is designed to operate at these temperatures and heat dissipation through the board layers is a design factor. While the motherboard does self-monitor CPU core and socket temperature, there is no "automatic" PC shutdown if the board senses socket temperatures approaching 90 degrees C. According to the "overclocking specialist" a socket temperature 20-25 degrees C higher than CPU core temperatures with a very effective CPU cooling solution is not unrealistic. Bottom line: if CPU core temps are kept in a safe thermal range, then socket temps approaching, but not exceeding 90 degrees C should still be OK. So, what are your thoughts?

have you tried the same with some Intel CPU to compare the difference from
the reported temp?

That is what I use, but all you are really saying is that the software itself is free of errors, it still relies on the CPU correctly knowing and reporting the silicon temperature.

And my silicon temperature most certainly is not 8C when my ambient temperature is 28C.

The CPU properly reports the temps, it is the software that is not calibrated correctly. Most application developers(coretemp etc) doesnt have the temperature and diode data needed to incorporate them in to their software and you get wrong/false readings from them.

The CPU clearly does NOT report the temps properly. Not at idle, not at half-load, and not at full load.

The problem here is a lot of people seem to have this completely unsubstantiated idea that the error at higher temperatures must be less than the error at low temperatures...that has never been proven for AMD piledriver CPUs.

have you tried the same with some Intel CPU to compare the difference from
the reported temp?

I have, I did the same with an Intel CPU (2600K) using an NH-D14 and using the same IR gun and same temperature monitoring/reporting software and the delta between the exterior fin of the HSF and the temperature reported by the CPU was about 20C at full load.

(meaning CoreTemp and RealTemp reported the 2600K was at ~85C when the NH-D14 fins were at ~65C)

 

[badandy85]

just thought id share my thoughts on this cpu. first time in a forum, but having realised there is next to no info about these cpus online I thought id give it a go!
firstly heat...im running a coolermaster eisberg, with 7/14 tubing, a 240mm rad with 4 fans and a 280mm with 2 fans. this just about handles the 9370 at stock when running prime95. overclocked to 5ghz (271*18.5) in my case, it hits 70c in only a couple of minutes. in games its cooler though. ive tried to find the max temp for this chip online and have even emailed AMD with no reply...62-65c for the 8350 I know, but I think this should be able to handle more. I let P95 heat it to 85c and only then did it throttle from 5ghz to 1.5ghz lol. people who say their temps are lower are probably mistaken, im using asus suite which take its readings direct from the crosshair mobo bios. coretemp and all the others give nonsense readings like 9c in a 22c room. guess they need an update for these chips.ive set my temp warning to 72c for now and it seems happy enough in games. even cinebench will bench no problem without getting too hot, just avoid P95 or OCCT. id like to add that I paid £170 for mine from overclockers, so only £20 more than the 8350. I think its worth it for the guaranteed 5ghz (if you have the cooling) but at the original prices its just too crazy! any advice or bios settings people have used is most welcome, took me a while to get mine stable in games at this speed.

[FONT=&quot]Hello guys,

I have an FX-9590 and been thinking about overclocking it. It will be my first time as I normally stick with default settings which meet my gaming needs. I have a question for you; how many of you have overclocked your FX-9590? And how far did you push it? Any tips for me?

Here are my specs:

CPU: FX-9590
GPU: HD7990
MB: ASRock 990FX Extreme 9
MEM: 16GB (4x4GB AMD Radeon RG2133)

I’ll be playing World of Warplanes most of the times, and probably Bioshock Infinite in between…[/FONT]

Greetings! i have had a bit of experience in overclocking the FX-9590, as i own one, and me and you happen to have VERY close to the same setup, as i am going to link for you here http://valid.canardpc.com/e58mx8

so far i can report that indeed, it is possible to get a stable overclock, even above 5.5 (not kidding here), the real trick is your ram homie. you'll need to keep your northbridge kinda low, around 250 or lower, and your multiplayer high. rule of thumb: dont go above 1.55v and dont go below 1.5. i'll ask my other homie andrew what he has. he got it up to 6.0 and got scared and immediately put it back down without doing a burn in as he is on hybrid cooling now listen, you're gonna have to be VERY careful, i wouldn't recommend anything with that cooler over say, 5.25 reliably without better a better cooling solution. i hope this finds you still interested, as regardless of what you will hear here, the 9590 is leaps and bounds better than the 83xx series, but you're gonna have to do some tweaking to make it stable. heat is an issue, you're gonna want to watch your RAM speeds, but YES, IT IS POSSIBLE TO GET TO 6. IVE SEEN IT, i'll ask andrew more questions today, and see if i can get him to give me his magic numbers and see where i can take them with our own setup

does anyone else smell bacon? why exactly did you come here? to troll?
*chuckles* i have never had serious problems with my motherboard reporting temperatures for the 9590. ever. lol.

 

[Phynaz]

HI trilith.

Welcome to the forums.

The issues around proper temperature monitoring of AMD CPU's is well known and you can get all the details with a quick Google search. So let's not call somebody a troll because they experienced an issue and are unhappy, okay?

 

[badandy85]

trilith....can you elaborate on your settings for 5.5ghz? i cannot get stable over 5.

 

[badandy85]

With regards temps for this chip, finally heard back from AMD tech support
"
Dear Andy,
Your service request : SR #{ticketno:[8200562020]} has been reviewed and updated.
Response and Service Request History:
We apologize for the delay. Your e-mail was misplaced by our server and was only now reclaimed and sent to the Global Customer Care team. I understand that you are looking for the max temperature for your FX-9370. If this is incorrect, please let me know as the information provided may change.
We are very sorry for the lack of response and extended wait time in dealing with your request as we had to check with related team for the latest FX specification. The max Tcase temperature for FX-9370 is 57 degrees Celsius. However, please note this Tcase temp is the internal temp within the CPU case which may be a bit different from the detect temp of the top surface temp on the processor. Please use other temp monitor software like AMD Overdrive, AIDA 64 to check the temp and update your BIOS and chipset drivers from the motherboard manufacturer for the best compatibility with the latest processor series."

 

[bgt]

My FX8350 always gives proper temps with speedfan, about 35C idle and fully loaded with prime 95 about 63C.
Roomtemp 20C. So........really no problem at all with temps.

(meaning CoreTemp and RealTemp reported the 2600K was at ~85C when the NH-D14 fins were at ~65C)

I get 25c Idle with 20c Ambient, that is a normal measurement . Using 7zip benchmark i got 50c.

FX8350 @ 4.4GHz no turbo 1.440v, 1866MHz ram on ASUS M5A97 R2.0(BIOS 2006)
AMD Water Cooler kit. (Fan speed is actually 600rpm, no mistake here)

I'll say the Probe II gets accurate readings, at least in this motherboard. I have also used ASUS Probe II in FM2 and it got accurate readings as well.
Never reported idle temps bellow Ambient.

 

[red_222]

Yeah, it does...another factor I've been contemplating with :|

After purchasing things like cars and cpus, remember one thing: YOU are the warranty.

That being said I would get a Corsair water cooler if I were you and you could easily hit 6.0ghz.

But I would think 8 integer cores @ 5.0ghz would be good for just about anything?

 

[caveman59847]

I am using the ASUSTEK Crosshair V Formula Z with the AMD FX 9590 at 4.8GHZ and I can't get it stable yet any higher but my Temps are at 40 C using the Corsair Hydro Series H100i . I have been using the Corsair Link and the AL Suite from aSuS to monitor the temps. I have not had time yet to play with the voltages but I am sure I could at least hit 5.0 GHz. If anyone has experience with the Crosshair and the FX 9590 voltages and can help a guy out it would be much appreciated
