i got yesterday my fx 8320 and i have a big problem too.My mother board is msi 990fxa gd65(latest bios)..My issue is i cannot pass 4 ghz barrier.i need help. My bios settings is
Cpu frequency=200(2200 board freq)
Oc genie lite=disable
Cpu core control=auto
Ddram frequency=1333 (1 have 4 ddr3 1333 ram=16 gb)
pcie ex freq=100
cpu voltage=1.5(insane vdrop cpu z show 1.5 but cpu load vcore drop around 1.45)
cool and quiet=disable
turbo core things=disable
After 30 minutes later with prime 95 i got error.
And i can post over 4 ghz (4.4 and 4.6) but those completly unstable even i give 1.59 vcore(near 1.52 volt with vdrop)
cpu Temprature around 55-60 and mobo is 40. But i saw aux on aida. it hits 20 minutes later 115 celcius degree?What is aux?Mobo voltage regulator?
What is my problem?Mobo or cpu or i forgot something?
Hello, sorry that you are having troubles . Hopefully we can help you figure out what's going on.
It looks to me like you have things pretty well covered as far as disabling power saving features in the bios.The only thing that I would ask is did you disable APS?(active phase switching)
Unless you were unlucky as far as getting a poor overclocking chip, I would expect to get 4.4 ghz out of that combo if your cooling is up to it.
The Vdrop you are experiencing is typical for a board without LLC, and it sounds like you have compensated for it accordingly. A couple questions about the chip, what batch is it and what does cpuid report as being the VID?
Prime 95 has been problematic for several people here with the vishera , have you tried other stability programs? OCCT , Intel burn test? OCCT will graph your voltages as it is testing and this will help determine if the power delivery system is working properly. I would suggest starting with it. Then if we get good results move on to prime 95 .
Take a look at settings on your ram , does cpuid report the timings and speed as being the same As the sticker on the ram indicates? Also it will report alternate JEDC standards for that particular ram.
For right now I would try to match the settings the sticker on the side of the ram itself possibly only bumping up the voltage a little. Later on maybe we can try getting some more speed out of it.
As for the aux temp, I get really weird board temp readings from software like Hwmonitor etc. on my msi boards. Just make sure you have good airflow across the vrms etc. It's remarkable the difference just an 80 mm fan placed over them will make, these board have a big heat sink just need a little air movement to make them efficient.
Could you please fill out your system specs in your signature? Always helpful to do that.
Check some of these things out and report back
