Safe to increase FSB?

post #1 of 11
Thread Starter 
My fsb is currently on 227 to get a core clock of 3.4, if i increase my fsb to 243 i can get a core clock of 3.4 by adjusting the multi, but i also get much closer to the stock ram speed of 1333mhz. Would 243 be too high? i do also adjust nb,ht multi to keep them within a safe/ideal range.

I have before booted with 250 previously too see what kinda of values i got, it was stable, i guess what i'm really worried about is much faster degradation of my components.

There's nothing wrong with taking a 243 bus clock rate.  My bus clock runs at 300 and it has been that way for more than a year and a half thumbsupsmiley.png well..... I did switch boards around late August so closer to maybe a year on my old 790XT board.

Pay attention to your other frequencies when doing so. Increasing FSB automaticly increases most other frequencies on the board as well, and I have heard stories about components failing from the increase(although I have yet to experience this myself). If you are new to overclocking I'll recomend you stick to increasing the multiplyer. However if you have some experience and want to overclock other components than the CPU as well you can combine overclocking the multiplyer and FSB untill you have reached your desired(and preferably stable) setting. There is plenty of guides, tips and other helpfull information around the forum.

The newer Phenom 2 are easier to boost the FSB than the first ones which were stuck on 200mhz. Now you can easily get a 223 or higher providing you boost CPU Voltage Northbridge voltage and keeping you HT around 2 grand plus or minus 10 percent.

Alright thanks, i'm cuurrently on 250 fsb getting a core clock of 3.5 and having my ram and ht link at their stock speeds is really nice. I'm really happy, it's seems stable though i haven't had the time to run prime95 for over an hour, but i have played various games for some serious hours, rendered videos, done day to day browsing, work etc for the past couple days and all seems fine. Let's see how it goes smile.gif

P.S. Im not really New to overclocking, just worried.

Sorry to highjack your thread, but it is about same subject. Asked about this before, but never realy understood it. So having an fsb on 300 vs 200 does exactly what? If adjusted so everything stays the same,ram,cpu,cpu nb, etc. What is diffrent? I read my 870a-ud3 should handle fsb on 332, does that mean it is "safe"? When increasing fsb, do I need to raise nb voltage?

xd, get your arse back from retirement and write me an article on that, will you? devil.gif

You might start to wonder if 0 know exactly what the diffrence is,hehe!

I heard that increasing FSB can lead to data corruption. It apparently increases your data transfer clock? confused.gif

I also heard increasing FSB with sandy bridge is really really bad. I've yet to hear of something going wrong though with overclocking FSB. Other than people saying stuff, not much proof out there...maybe because alot of people stay away from it.

Now why increase FSB? It's so much easier and safer to increase multiplier...

Cpu's with locked multipliers of course. Aka. Non black edition or "k" models.
