Hi all,

I have just bought FX-6300 and it works fine for my needs (using internet, gaming from time to time). I am also planning to do small OC on it. Today I have occassion to buy used FX-8320 CPU, which has been taken out from the graphical station, where it was working 24hours a day for one year. It has not been overcloked - worked on the standard frequency.

Price is more or less the same for me.

What would you suggest? Shall I go for FX-8320 or stay with my FX-6300. For my FX-6300 I have 3 years warranty, The Fx-8320 goes without warranty as the invoice is lost. On the other hand wIth the FX-6300 I have "only" 6 cores, the FX-8320 has 8 cores - but will I really notice the difference?

Please advice.

The safer solution here is to stick with your 6300. The main reason is that the 8320 won't come with a warranty and if it has been used 24/7 like you said, there is no guarantee it is in great condition. As far as performance goes, yes, you will see a difference, but only a minor one. But as you said you only game from time to time, I'd suggest sticking with the 6300.

Yes the warranty was my main concern. The guy who is selling it says that working 24/7 is not so bad as the electronical components are being damaged mostly while turning on or off the PC, but I was not convinced. So I probably will stay with my FX-6300 as it's gaming abilities and OC potencial is not so bad comparing to FX-8320. I also have read that this 8core processor is getting higher tempretarues and has bigger power consumption. Is it true?

I will only add that I am using SilentiumPC Fera2 cooler - not the stock one.

I never saw a CPU fail because it ran 24x7 even when they were more than 10 years old.

And it should not it have time to cool off from time to time? Sorry if my question is lame, but I am not technical guy.
What's more this is my first AMD set so I don't know how they behave and what are their "normal" working temperatures.

I didn't mean to say that the chip won't be in good condition, I would just b skeptical as you don't have a warranty to fall back on if something does end up going wrong.

Cooling off doesn't help a CPU. My systems that had the least long term issues were on 24 x 7. I've noticed the same in data-centers where systems are powered on all the time and it doesn't matter if they are AMD or Intel based servers.

I agree that warranty is the issue, not that it ran 24 x 7.

So if there is no warranty for this FX-8320 you would suggest to stay with my FX-6300 which still has almost 3 years of warranty?
I was wondering if the FX-8320 is so better that it is worth to risk, or the difference is not very noticeable, and it is not worth to risk.

AMD know the manufacturing date of each CPU. According to http://support.amd.com/en-us/warranty you only need to provide the model and serial number. You should make sure the CPU is a retail unit.

I will check if this is aplicable also in Poland where I am from. But thanks for the info.
One additional question - if you are CPU expert maybe you will be able to help.
I have just ran this FX-8320 with the Sabertooth board from Asus and I have noticed strange issue. The temperature of the CPU was varying a lot. I mean in idle there is arround 40C, but from time to time it suddenly raises to 50-60C without any reason (while f.e. reading the email or browsing the internet). What was most suprising - one time it has rissen to 60 while viewing the BIOS settings! Do you know why is it happening? Is this a CPU issue or the mobo?

As soon as the CPU does some work, the temperature will rise; reading emails or browsing the Internet causes CPU activity. While in the BIOS settings, the CPU isn't idling; therefore seeing higher temperatures than you see in Windows when the system is idle is normal. Check the temperature while running Prime95 stress test; it shouldn't be significantly higher than what you observed in the BIOS. Are you using the stock cooler that came with it?

Perhaps you could have both? Purchase the 8320 and keep your 6300, this way you can run the 8320 and have your 6300 to fall back on if need be.

Yes for testing purposes i stayed with the stock cooler, and the nose while the CPU is getting higher temp is really annoying.

I was surprised because I have used Fx-6300 earlier and it did not have such temperature peaks.

The noise of the AMD cooler on the FX8xxx processors is well known and that's why the Cooler Master Hyper 212 EVO is so popular.

I've bought a few used processors and I never had issues with them.

I own and use both on a day to day basis. Absolutely no difference for most users. The 6300 is easier to cool and easier on the vrm section of the mobo.

Get the 6300, no warranty on the 8320 doesn't sounds good.
October 15, 2014 9:41:02 PM

Thanks a lot for your answers. I decided to stay with my fx-6300.
