(HELP) Phenom II 970 BE voltage questions

post #1 of 15
Thread Starter 
im working on overclocking my phenom II and in the bios i changed my voltage settings a bit and turned off cool & quiet. my Vcore is set to 1.452, however in core temp it displays vid of 1.400. also cpu-z shows readouts that vary with load. my multi never drops and it never shows a differint vid but the readouts range from 1.42 - 1.48. occt always detects an error when its testing 25% but never an error at full load. Its stable working hard, but sometimes it blue screens just sitting not doing much. Anyone know what i should do from here?

system specs

mobo:MSI 785GT-E63

CPU:AMD Phenom II x4 970 BE@4182Mhz (204x20.5)

CPU Cooler: Corsair H70 w/modified shroud (much better flow)

PSU:ARC Tech 600w

Hmm it could be your ram, but since its a black edition you probably left the fsb untouched. What are your temps? I'd recommend speedfan if you want to check the vcore, since it could vary. The VID is the voltage the chip is made to use. 1.4v is the normal voltage. Now you can go up to 1.5~1.52v without problems. More than that will require caution. Set the vcore at 1.5v and you should be good to go

Not familiar with your MB but do you have an over volt or CPU load line function in your bios? The reason I ask is because your voltage will increase when under load and decrease to normal setting with no vdrop when enabled. which might explain your crashes when idle or doing basic computing. Also...1.5 volts is not recommended on that cpu, I run 1.375 idle and 1.40 load.

i fully agree 4.1 for then fets on that board is to high.

4ghz @1.4/1.42 should be fine


you have a very good cpu and a mid board don't exspect to much


or you will kill you board in a week

It seems like you oc is not completely stable, try lowering the oc to 200x20.5, maybe that'll give you better stability.

to answer a few questions first. its never gotten hotter then 50c under load and idles at 30c. and i found out my mobo had APS (active phase swtiching) controld powerusage on demand. im thinking thats like LLC. also i have tried to run 200x20.5 still fails durring idle. im going to look in the bios for the APS function and try to disable it

You'll need it.

OP you may want to have a look at the orange-bolded link in my sig concerning VRMs...
I don't consider any overclocking fine on that board at all. MSI AMD board (released in 2010) VRMs are so bad that they can fail despite mosfet heatsinks and even at 1.4V and less, as with some of the horror story examples in my article.
