stock voltage for fx 8350

[ChrisDFW1]

I want to play around with ocing on stock voltages but bios is set to auto. I have read a hundred posts on many forums. Does anyone know what the stock voltage is for this cpu?

 

[coolcole01]

when its down clocking itself can go down to .89 at 4.2 usually around 1.39

 

[coolcole01]

for oc though you will probably want to be in the 1.4 range just remember if you keep it at auto and you run it at a higher clock it is most likely unstable

 

[ChrisDFW1]

well right now on auto it is running at 4.1 at 1.2875 cpu voltage

 

[coolcole01]

each chip will be different and each board will volt it differently like mine is completely stable at 4.67 with a voltage of 1.39 but my friend has to have 1.46 to keep his stable

 

[ChrisDFW1]

Ok then. I have an M5a99x evo board... my question is what is the stock voltage for this cpu. Like i said what i want to do is play around maybe a step at a time with stock voltages without raising them. I just want to know what my stock voltage should be before i start this.

I read on a couple of forums that 1.35V is the stock voltage

 

[coolcole01]

thats not really how it works what you would do is start higher by overvolting and then reduce the volts till it becomes unstable here is a good little guide

[coolcole01]

just remember that the top you would want to volt a 8350 is about 1.5 and from there down if it is stable its good

 

[ChrisDFW1]

i dont really want to go any higher than 4.5.. i was thinking of trying 4.4 at 1.35 and see how that works

 

[coolcole01]

at 4.5 at 1.35 the computer will boot and it will play but if you try to stress test it its gonna fail like a champ

 

[ChrisDFW1]

yea a couple of people said 4.4 is the highest you can go at 1.35 and moving up to 4.5 requires upping the voltage. Maybe i will try 4.4 at 1.35. it has worked for other people

 

[coolcole01]

but say that 4.5 is your number what you do is start at 1.35 then go into the bios and use the -+ symbols on the far right of your keyboard and bump it one time everytime you test till its stable the reason people usually start higher is because of the chances for errors and bsod at lower voltages

 

[coolcole01]

you can go pretty high on minimal voltage the computer will run but its essentially being undervolted and it will not be close to stable for most but you never know you could have won the silicon lottery and the chip will be awesome at low volts mine is. What cooler do you have?

 

[ChrisDFW1]

im using the hyper 212

 

[coolcole01]

thats a fine cooler you should be good to 4.5 just be aware of temps remember 62 on the cores(package) and 72 on the cpu socket and as you overclock make sure you bump up the cpu/nb and the nb

 

[ChrisDFW1]

ok. i am to tired tonight to mess with it but i am off monday and will see what i can come up with. So you think i should try leaving it at 1.35 and just go up 100 at a time from the 4.1 its at currently?

 

[coolcole01]

no i personally thin you should start at 4.5 and 1.45 and see if its stable and what your temps are if its not stable you will need more volts if it is then just start drawing down the volts. the fx 8350 is a great oc it will hit 4.5 no problem the temps will be your only problem

 

[ChrisDFW1]

is there something i can use to show if im stable or not without waiting for a lockup?

 

[coolcole01]

yes there are a lot of different tests prime95 is probably the best but its really opinion basically you will run the test and it is gonna heat that chip up as hard as it can and while it is doing that it is gonna check for errors

 

[coolcole01]

if the cores start failing (errors) then you know you need more voltage if it runs fine but is to hot then you need less voltage

 

[ChrisDFW1]

ok thanks so much for your input

 

[coolcole01]

no problem bud if have any problems there are a lot of knowledgeable people on this site.
