Overclocking the AMD FX 8350 to 5ghz

Prime95 sucks for FX chips. You will mostly get errors regardless. Prime95 needs to update there software to include FX compatability.

Many people including me are getting 4.70GHz with 1.4v MAX and 4.40GHz with NO Increase in Voltage. The OP should OC to 4.40GHz and leave everything on Auto, if he succeeds, he could have a good batch. I don't buy this notion about jacking up the Voltage then OCing.

You should attempt the OC then up the Voltage if required. How do I know? I was running 4.80GHz with/ 1.385v Rock Stable. But I favored the higher Bus Speed and lowered the CPU speed 100MHz less & upped the voltage to 1.4v. I guess the bus speed requires more voltage for stability.

All you can pull on your Phenom II is 4GHz? LOL, that is childs play.

I think you need to get off your high horse and stop insulting people just because their overclock isn't as high as your. This isn't a pissing contest.

Screenshot and validation or it never happened, also with what kind of cooling because I seriously doubt you could that with air or water.

Prime95 alone is a bad gauge weather or not his system is stable. It's a good first step but running a LINPACK/LAPACK based stress test and a video game should give you more accurate result as far as stability is concerned in addition to P95. If you were a "veteran overclocker" you would have known this. No offense.

Hey Simmyen, I think 5GHz on air is hard to get, if even possible. I tried with mine, it took 1.52V to make it stable enough to boot into Windows but it wasn't stable for anything other than simple tasks.

I haven't got mine overclocked right now so I can't offer any good advice. I do have the GA970-UD3 and the Noctura D-14, similar to your setup.

AMD chips are so cheap right now, I don't worry so much and therefore say, volt it until she craps herself.

Have fun and good luck.

That is a very important fact that a lot of people seem to forget with newer boards, Auto and Default are not the same thing, I did not realize this until I was OC'ing a 1090T in a ASUS M5A88-M and was doing incremental multiplier increases with 5 minute Prime95 runs. At first I thought I was getting excellent speeds from the stock voltage until I checked and noticed my VCORE was at 1.5V. The setting was AUTO in the BIOS. Always a good idea to find out the stock voltage and set it to that manually when you begin your trial and error increases.

EXACTLY
the FX chips have a WEAK FPU and prime wont tell you shit for stability on those chips at least someone here knows what they are talking about

<offtopic>don't waste your breath his comment(about prime95) told me all I needed to know about his ""overclocking ability and general knowledge of computers"" hes on my ignore list I recommend you do the same I may be a asshole but at least I know what I am talking about<offtopic/>
back to the topic at hand 5Ghz might be asking a bit much of that cooler as other people have stated if you are dead set on 5Ghz then a water cooling kitt are gonna be in your shopping cart in the near future

I have no idea why you guys are arguing stability tests. Prime95 does the job. In some instances Prime95 will pass and linpack won't In some instances Linpack fails and Prime95 won't. There is NO test that is 100% accurate for stability. Prime95 WILL stress the NB harder than Linpack if you guys don't know at 2.5 hrs. Anyway, stability is in the eye of the beholder when overclocking. pass Prime95 3 hours and just about every system will be stable enough to through anything at it.

Onemoar and Aquinas your not by far the ultimate athority here. You both spread a lot of BS at times so you need to both keep your panties on. If you two would just french kiss you may be a nice couple! LOL

My apology, You aggravating.......




If you have to ask if 6 GHz was done on water, something is wrong here.


Here is a review I did for a site I used to review for. That Drdeath(Jim) guy is me.. LOL. I am sure you will ask for a photo ID.
The subzero results are on the review....

I'm pretty new here and glad to have joined such as awesome community. Not here to start some flaming post but there is no excuse for blaming a fully functional piece of software which is world known as the go to stability test. If you are receiving errors with Prime95, the OC is unstable, it may never BSOD, it may run for a year without any issues and there may be no concern to change any settings for just Prime95 to work but Prime95 is a intense piece of software that has a simple rule run iterations of Lucas-Lehmer (Is this mersenne number prime or not), and to do one after another requires the previous one to be correct. If you receive an error, your hardware made a mistake, a miscalculation. I don't know about you guys but knowing my CPU made a math mistake is unacceptable even if it will never affect my daily computer use. Prime95 is one of the only few apps that give you true bullet proof CPU stability results.

I have seen and owned plenty of machines that where 24H prime stable that still crashed in certain applications
Prime95 and ESPECIALLY on AMD's FX chips will not give you a accurate measurement of stability no 'stress test' will Simulated workloads will never give you a 100% reliable result all they will do is tell you if you got the settings in the right ballpark
saying that prime95 is the best way to tell if a machine is stable is like putting your car on a dyno and running it for 1000 miles and saying that you are absolutely 100% sure that it will be ok to drive it 5000 miles non stop and you are 100% sure it won't break down EVER

Anybody that says all you need todo to test a overclock is run some stability testing software has clearly not been doing it very long

I've got a thread going here with my OC journey for this chip. Having issues going past 4.7 but that's a pretty good boost. Hope some of the info and pass/fail, etc. helps you in your quest as well.

I believe you misunderstood the discussion regarding Prime 95 and FX chips. Even at default speeds,Prime 95 gives errors on FX chips, reason they have to update the software so it can properly recognize the new chips.

Anyhow, I think the Intel Burn Test is the best to measure stability.

Oh no I understand completely, I'm just in disagreement with that statement for I am running the same CPU and do not receive such errors with Prime95. I'm simply stating my opinion that If I do not see an instability with my FX-8350 and Prime95 then I would not say Prime95 is at fault. Yet again I could be completely wrong because I may just have a "golden chip". This would be a good topic to start up in a different thread, with some screenshots displaying stock voltages & frequencies with errors in Prime95.

But anyways in regards to the topic at hand I've gotten to 4.8GHz @ 1.45V but found it to be to hot to stress test with my air cooling. If your not to familiar with overclocking and are unsure about the correct voltages to use, some motherboards give you color coded warnings in the BIOS when you start increasing them to high, such as yellow (caution), red (dangerous). If these are available in your BIOS then stick with increasing the voltages into the low yellow ranges and only play around with the NB, CPU, and CPU-NB voltages while performing your trial and error increases of the CPU Multiplier and/or Bus Speed. Everytime you perform a stress test always keep some sort of temperature monitoring software open such as AIDA64 and watch for any drastic changes to the temperatures such as over 10c on the motherboard and keeping the CPU under 60c is a good idea.
