I'm new to forums, so if I've done something wrong, I apologize... But anyway, I'm a little concerned about overclocking with bus speed as I don't want to damage my motherboard. My problem is I'm a little bit paranoid that I may be damaging the board. Basically the stock Bus speed is 200MHz, I have overclocked it to get my CPU up from 2.7 to 3Ghz (Bus speed now at 223), I know it tinkers with other components, so I changed my ram speed a setting below original because I don't see the difference with RAM above 800Mhz (Personal opinion), no voltages were changed, PCI-E is in async with "CPU speed", so it's still at 100MHz, but anyway... I know I'm going on a bit but I just want to know if I have overdone it... I haqven't ran no stress tests to see if it's stable but I have played a few very intesive games that stress the cpu as it's not exactly the latest anymore 😉

CPU: AMD Athlon II 215 (Not unlocked)
RAM: 4gb 1333MHz but now running at 1189MHz
Motherboard is an Asrock n68-vs3 UCC Socket AM3
AMD Cool n' Quiet is off
Cooling is good enough anyway, I have a Coolermaster Hyper TX2 (21°C ~ 38°C)
(No voltages touched) Haven't ran into a problem yet...

Would be grateful if anyone replies and like I said before, if I have done something wrong during this please let me know without telling me off 😉
Thanks,
Corey

First, I must say that I never owned a AMD cpu but without changing the vcore voltage the worst that you can have is a failed boot and need to reset the bios (as long as you don't put crazy values on FSB).

You are doing things as you should: AMD Cool n' Quiet is off, RAM is bellow its limits and PCI-e is at 100 Mhz, but you need to do stress tests.

It is reasonable to think that your cpu can achieve 3.0 ghz easily (and the only way is increasing the FSB) but as you increase it, small steps at a time, you must do stress tests to know it's limit and when you find it, just set it a bit lower than that limit.

The stress test will show you the limit of your cpu at a specific vcore voltage, if your settings pass the stress test then you...

The stress test will show you the limit of your cpu at a specific vcore voltage, if your settings pass the stress test then you will know it is all ok, until you do the tests nobody can answer that your settings are ok, so, get prime95 running for a few hours and monitor the temperatures, if there is no error you are just fine.

If you are looking for more performance, you will need to increase the vcore voltage, also small steps at a time, if you want to do that, try to find old posts about overclocking your cpu, it will be easier for you to have an idea about the usual settings other people did, but, take note: all cpus are different in terms of overclocking.

Hi.

You are doing the things in the right way, but you forget two thing. NB and HT also depends of your bus speed, so try to keep the HT and NB the most closest to 2000MHz for now while you get an stable core speed.

I suggest you do an stress test for a long time period, 2 hours is commune but I have seen overclocks failing at 6 or 7 hours.
 

Thankyou for your reply, I will take this into consideration! At the moment I'm back down to stock, no difference in performance, but there's one problem now, I've gone back to stock (FSB 200) but everything's still a tiny bit overclocked, I'm not too sure why, I even tried a clear CMOS but it's still the same, not too worried as it's not exactly massive 😉 But like I said, thank you!
 

Thankyou for your reply, all things considered! I'm not at all worried about temps because the max it has ever hit is 38°C One thing I have done differently though is disable spread spectrum for everything, I've heard it hogs performance but cuts back on interference, nothing has gone funny yet! Another thing as well is that I'm not too sure if this interference could be audible with small earphones, but I still don't hear anything, not even white noise! Thankyou though! (Going a bit off track 😉 )
