AMD FX 9590 Overclocking/reliable 5.0Ghz advice

[IPoteven]

Hi everyone, I just bought a new CPU because my Fx8350 broke(4.7Ghz, combination of bad OC, beta BIOS, etc). I got the Fx9590 cooled by a Swiftech H320 and Asus Crosshair Formula Z mobo. I was hoping to get some advice to OC my CPU or at least hit the 5.0Ghz. Right now, I run default settings and I CAN'T hit 5Ghz. On idle, my CPU runs the 4.7Ghz base clock, on load and Turbo enable, it downclocks to 4.5Ghx-4.0Ghz depending on cores. My temps are under 50, low 40C on full load. Here's what I'm looking for:

- Max CPU temps (I want to stay within factory temps limitation IF POSSIBLE). I think it's 62C
- Stable OC (I do 3D rendering, so sometimes I can let my PC full load for hours/days)

- Why I can't hit 5.0Ghz with TURBO on(It downclocks to 4.5-4.0Ghz instead)
- How to get low voltage(My 8350 with gig 990FX-UD3 mobo was at 4.7Ghz at around 1.46/1.49v or +0.750)
 

Any advices?

Whats its max temp underload? Might be downclocking cause its getting too hot?

You got a FX, didnt learn your lesson, and got even a worse FX?

disable turbo you dont need that on anyways

 

i assume you already diasabled the usual? (turbo,cool and quiet,c1e,hpc,svm,etc)

 

for 5ghz you may have to bump vcore to 1.47 or 1.48

9590 = Overclocked 8320

Temps are in the low 40, maybe their requirements for 5Ghz are too high

Cost too much to go Intel right now(new mobo + CPU 4790K. I ll wait to get a 5820K, DDR4, mobo when prices go down). I bought a new mobo because I thought the other was dead and CPU ok, but no, the CPU was dead(Beta BIOS, putted my tested OC I was running for almost 2 years, it stopped booting, randomly). Instead of buying a FX8350 when I bought a good mobo that can run a FX9590, I went with the 9590(50$ more, OC and cherry picked 8320/8350 I know)

disable turbo you dont need that on anyways

Yup, everything is disable

[exxco]

you could bought another 8350 or 8370. Will be better

[IPoteven]

Nah, FX9590 are cherry picked of those CPUs(8350, 8370, etc.), so I can get worst by going down. My last 8350 was a bad OC(4.7GHz, 1.46-49v or +0.750, full load max 50-55C.Maybe it was me the bad OC ). With the 9590, if I keep it base clock(4.7Ghz), I have lower voltage and temps.

Unlike most people i am not going to critisize your cpu choice, theres nothing wrong with it. Yes ur correct, the max is 62C, Turn off turbo boost and run your RAM at no higher than 1866 MHZ, this will keep the OC stable. Next go to your digi+/vrm control area in the bios and set loadline calibration etc to extreme and cpu current capibility to the max %, keep your fans at a high CFM (thats still comfortable) and then your temps should be ok, to get the OC stable set voltage and multiplier to manual and boot up, then add 100-200 MHZ at a time until more voltage is nessesary, go as high as u can until your temps go above 62, as which point you are at your max OC. If you have any questions let me know.

Thx man, I'll try this out after work. My ram kit is a 8Gb G.SKILL Ripjaws X Series 1.5V, can I break it if I go 1886Mhz(I never OC Ram)?

good luck, no u cant break it, its just when u OC, lower ram frequency makes an OC more stable

I tried a bit, I was at 4.9Ghz @ 1.52 volts, temps are a bit high(60-67C). I think the most I can cool with a swiftech H320 is 1.5v. I don't know how people can have some 8350 to 5.0Ghz with less than 1.45-50v. Maybe they go higher temps, less stressfull test(I'm using Prime95 small FFT test). I need to go push-pull I think.

[WaitForMeImOnDialUp]

prime 95 is not a good test for fx dude, sometimes it will make a core fail at stock speeds.

 

when i oc'd my 8350 i stress tested with intel burn test, just a 10 pass standerd test if it passes its stable.

Okay... Here's the problem with your test. You used Intel Burn Test on an AMD CPU. OCCT is the best all around.

[WaitForMeImOnDialUp]

yeah dude intel burn test is better on fx8 than prime 95 is. i had 4.8ghz stable on a 8350

[IPoteven]

I tested 20 min on Prime95, small FTT. I was stable at 4.9Ghz @ 1.475v in BIOS, 1.488v in CPU-ID. I had to open my window to keep my temps a bit low, so I might need to go push-pull to go higher.

[-rascal-]

You probably can't go much further without adding quite a bit more voltage. Sure the FX-9590's are binned FX-8350, but they tend to use a lot more voltage.

Maybe I was one of the lucky fews, but I've got a FX-8350 running at 4.8GHz with 1.390 ~ 1.404V...and I'm using a 3+ year old air cooler (the original Thermaltake Fro).

Also, I'd recommend using ADIDA64's built-in stability test instead of Prime95.

[IPoteven]

Next test will be OC with FSB

My FX 9370 factory voltages are; 0.789v(1.4Ghz) - 1.538v(4.7Ghz). With a D15, Prime95/Intel Burn Test, it stabilizes at 76 degrees Celsius, in a fairly airflow restricted case and ambient temperature of around 26 degrees Celsius.

 

Correction:

it is 4.6Ghz, set by 200 x 23. 4.7Ghz was too toasty for my liking.

76C isn't it a bit high temps? If you are gaming only, you might never use the CPU at 100%. , so high temps at 100% load isn'T a problem.For me, I use it everytime I render 3D stuff, so I need low temps(within the factory specs). I could OC it as far as i can, test it out with a game that use a lot of CPU to see what are my temps.

Normal gaming temps tend to be around 60 degrees Celsius. [skyrim, COD]. What I wanted to communicate, was that with one of the best air coolers(D15), on a 9370 with 1.536v, you will hit these temps. So may be get an AIO water cooler if you need lower temps. The higher TDPs(220W) on the 9XXX CPUs is achieved by uping the volts to above 1.5, not the case with 8350s, which based on the silicon lottery can do 4.7Ghz with 1.4xxx volts. So if your are sensitive to temps, be ready to provide a way to dissipate the heat quickly or try your luck with an 8350/70 again. 

 

Remember, when AMD launched the FX-9 series, mere mortal were not supposed to get them, because of the VRM/heat requirements.

Can confirm it...prime fails on one core -  FX8350  at 4.5Ghz 1.4V(1.33-1.35 load due to no LLC on the Killer board), yet AIDA64 stability works fine for 2hours(the most i tested it), Cinebench R15, rendering in Vegas 13, and everything else I throw at it...only prime is failing....and temps barely pass 55 on socket and 45-48 cores...so I'm well under the 62 degrees threshold.

[thebennyboy]

I use Asus Realbench to stress test my CPU. Seems to be a bit more realistic than Aida64 and Prime95, however it will make your CPU gets pretty toasty. It gets my CPU up to about 70C on the socket temp and about 55C on core temps, that's at 4.8Ghz 1.42v.

Did you try to undervolt your CPU, It might be good to lower your temps. From factory, they are using A LOT of voltage to get their rated speed. For the 8350/70, I think you can get as good clockspeed than 9370/9590, if you win the silicon lottery IMO. My old 8350 was 4.7Ghz at 1.46-49v(tested with Prime95), which is meh. I saw a lot of people with 8350 going high Ghz(4.8 -5.2) with 1.3X-1.4Xv, but testing it with a less stressfull test than Prime95. If it's for gaming, they will never use 100% of CPU, so they can push it to 5.XGhz, 50-75% load in X games, 1.5Xv, 55C-60C.
