Ready to overclock my AMD 8350: What voltage/multiplier should I start at?

[CooLWoLF]

I am ready to give my AMD 8350 a go at overclocking. What voltage and multiplier is a good, safe place to start at (on the average) for this cpu?

 

[Suferbus]

Bob, I just did an experimental overclock on my 8350 with just the multiplier, and I will list the steps for you. I also have watercooling loop, so this will only work as long as you have one, and should get you to a stable 4.6 Ghz, and should Prime95 test at under 58c full load:
Reset bios to default. Go in a disable amd cool n quiet, turbo, core c6 state, c1e, svm, hpc mode (if you have that in your bios). Put overclock in manual mode, then set your multiplier to 23. Set your cpu voltage at 1.5 and run prime 95 for at least 15 min. if no failed cores, back voltage down 1 notch and run prime 95 again. keep backing down 1 notch on voltage until a core fails, then go back up 1 notch on voltage and re-run prime 95 for at least 30 min. If no failed cores, you should be good @ 4.6Ghz and on temps. This is a safe procedure, just watch your temps while prime95 is running. Put a 15c offset on prime 95 to be safe. You should end up @ 4.6 around 1.46v and under 58c under full load depending on your cooling system. Have fun!! ~~ Suferbus

Surferbus, its the OP thats whats advice on how to overclock, my cpu is already stable at 4.5. And you shouldn't ramp the multiplier and set the voltage to 1.5v on the first attempt, thats a good way to fry you mobo and cpu, 1.5v is the beginning of the danger zone if you don't have you setting tweeked. You should raise the multiplier little by little and change the voltage only when needed for stability.

I would advise him not to push it further with that board.

 

[Suferbus]

There is nothing wrong with his motherboard. It will be stable to 4.6. I pushed my Gigabyte 97a d3 to 4.7 and it does not even have heatsink on VRM

 

[Suferbus]

There are plenty of overclockers that have overclocked higher on worse mobo's that Bob has. There are articles all throughout the forums. Stop scaring this guy.

Im running with a crosshair V Formula Z Mobo and a AMD 8350, liquid cooled by a Corsair H100i, And it performs like a champ!

running 4800 Ghz @ 1.5v and my CPU temps dont push past 55c

Very good CPU!

I have the exact same setup anyway i can get all of your details im currently new to overclocking wouldnt mind learning the ropes.

i have an asrock 990fx, amd 8350 going with a hyper212 evo. How much voltage could i manage to get to while staying on the safety zone? I'm at "1.4375 V" according to the BIOS settings but Idle is 1.408 and sometimes 1.424 and with prime95 running it's 1.312 (idk why such a big gap). Currently at 4.49Ghz. Help! I can't get stable. 21x214

Bustinya did you turn off AMD cool n Quiet and all of the AMD auto settings in your BIOS? Your voltage should not be fluctuating so much. You will not be able to attain a stable overclock with the AMD CPU "AUTO" features on--- Also, as long as you stay 1.5v and under, and the temps stay under 62c you are good----voltage creates heat, and obviously higher overclocks will require more voltage, etc. Just keep a check on the temps using a good temp program, and make sure you put in a 15 deg offset for AMD FX series chips, as they do not have temp sensors on every core as Intel chips do. Make sure you run Prime95, Small fft's and watch for failing cores--If your new to OC'ing, start by using the multiplier and remember, what works for one CPUwill not necessarily work for the next chip, even if it is the same cpu---all cpu's are different and have different capabilities----have fun and let me know if i can help you!!

More tdp on vid at this Oc might want more psu
Oh also changing vid to 100% fan drops CPU idle temp from 39c to 36c.
All fans, cooler at 100% wife hates it.

I was able to set mine to 4.5 MHz, 22.5 multiplier with voltz set at 1.3 steady 55 temp max 57 and prime85 ran fine. I have antec 650 khueler. Are the voltz ok? Yours are quite a bit higher...

The main thing to watch is temps---1.5V is the standard max for the FX Series Processors, but I have heard of people going past 1.5v, though that is rarely needed, and temps can skyrocket, so you would have to have an awesome cooling solution---With each processor having different capabilities, my 4.6 oc with 1.46v might be 1.3 v on another 8350 or 1.5 v on yet another one, it all depends on the processor, all silicone is different---if you have a stable 4.5 at 1.3 that is awesome and it sounds like you have a good chip--As far as my processor at 4.6, i loose stability if I drop my voltage any further, so I happen to have a 4.6 Ghz processor at 1.46v- good luck with your overclocking endeavors!

 

[KillerDisturbed]

Not too bad.


Hey Man, my Skype is KillerDisturbed, please add me, as I have the same motherboard and CPU as you, about to get a watercooler, and I"m interested in talking about overclocking with you. Damn nice results man!

 

[Sander te Winkel]

Try a 22.5x mulitplier with 1.45v of voltage, this should get your cpu stable at 4.5GHz

Funny thing is, I got my FX-8350 to 5 GHz at only 1.325 volts

So you're telling me that you run it on an undervolt, at 5ghz?

Sure buddy. Show me 30 minutes of Prime95 Small FFT's and I will believe you. Maybe you can boot at 5ghz, maybe even run Firestrike - but nothing more.

My 8350 ended up being a great OCer for 4.8ghz, but needs a bit above 1.5v just to run Firestrike at 5ghz. My best Firestrike - http://www.3dmark.com/fs/5355561

I've also managed a Firestrike at 5.2ghz but it's hard to replicate because it was so unstable.

Sorry but it's hard to believe even at stock voltage, especially an undervolted 8350 will do anything above 4.5ghz, let alone 5ghz. Pics please.

Nice, this is the daily OC that I've been running the last 14 months or so http://valid.x86.fr/0tlykj, haven't had a single problem with it Also it's 1.44v, but I noticed when I validated it says 1.428v.

I am ready to give my AMD 8350 a go at overclocking. What voltage and multiplier is a good, safe place to start at (on the average) for this cpu?

My previous post showing 4.6Ghz became unstable so I reduced the the bus frequency multiplier to 222 rather than 224.

The F12 feature allowing you to make a screenie to a Flash Drive while you are using UEFI, here is one I made recently after OC'ing my FX8350. It is being cooled with a Hydro H60.
