Hi,
I bought a few days ago a FX8320 to replace my Phenom II x4 965 BE. Willing to OC it, first I tested it with stock frequencies and I'm rather disappointed.
Here are my current specs :
-FX8320 @stock
-Asrock 970 Extrem 4 (UEFI updated)
-8 Go Corsair Ballistix PC12800
-Sapphire Radeon HD 7950 OC
-Noctua NH NH-U12P SE2
-Antec HCG 620W modular
-Factal Design Define R4 with 6 fans
-SSD Samsung 840 120Go + 1To HDD
There are the charts I get from OCCT :
-Witt large data set, 16 Threads for 2 hours this night :
Frequency : http://puu.sh/6FVJt.png
Temperature : http://puu.sh/6FVJL.png
Vcore : http://puu.sh/6FVJU.png
CPU usage : http://puu.sh/6FVK3.png
FSB frequency : http://puu.sh/6FVK7.png
-As the variations were too big and unreadable, I made a new stress test this morning for 10 minutes, with the same settings :
Frequency : http://puu.sh/6FVWO.png
Temperature : http://puu.sh/6FVX1.png
Vcore : http://puu.sh/6FVX5.png
CPU usage: http://puu.sh/6FW11.png
FSB frequency : http://puu.sh/6FVWE.png
And here are the settings I changed from the UEFI regarding CPU and RAM :
-CIE disabled
-C6 disabled
-Cool n Quiet disabled
-Spred spectrum disabled
-Thermal Throttle disabled
-Turbo core disabled
-Vcore set to 1,4V @stock value
-CPU load line calibration :1/2
-Frequency, multiplier etc... set to their stock value
-Profil XMP 1,3 1600MHz loaded
What I find abnormal :
-Vcore is unstable, are variations from 1,35 to 1,38 normal ?
Yet my PSU and my MB aren't that bad. Although they aren't high end, they shouldn't be in pain @stock frequencies et had no problem rising my Phenom II up to 4,2GHz.
-Why is there this periodic fall in Vcore, frequency and temperature ? Is it a measure bug ?
-Why is the temperature so high whereas my cooler et my case are far from being so bad ?
Room temperature is around 20-21°C. NH U12P is mounted with its two fan with maximum speed, two big 140mm and a 120 expel air from the top and three breathe from the bottom. I use the Zalman ZM-STG1 as thermal grease (maybe not the best but easy two apply).
Also, expeled air from the top is almost cold ! Way cooler than the one I had when my Phenom II was running @4ghz. All this makes my think that the temperatures reported by OCCT, although plausible, are incoherent.
-Beside, since I changed my processor, I don't have the same probes in OCCT anymore : I now don't have the cores' temperatures anymore but I managed to get them back using AMD Overdrive. Still they are quite odd : One is blocked around 85, an other at 125 and the last ones at 29. Also, new probes have appeared : Package, Air Flow, Assembly, and TMPIN0. Is there one that might be important ?
Where could the problem come from ?
Is it possible that the cooler/the thermal paste are poorly mounted ? Still I didn't have the impression to do something different from usual and all the fans are running well.
Can the probes be poorly calibrated ? Can I recalibrate them ?
Is my UEFI well set for OC ?
Thanks for reading, I hope someone will be able to help me .
Waiting for an answer, Lucas.
PS : I tried my best to write proper English as it's not my primary langage, I hope it's understandable.
