Is there such thing as too high of a FSB?

post #1 of 9
Thread Starter 
I'm trying to get my system stable at 3.4
I originally attempted doing it at 378x9 and tried for hours to make it stable...messed with endless voltages, the gtl, everything people suggested and had no luck for some reason.

Gave up and now a few hours later I'm antsy to try again. I decided to go with a x8 multi.

Currently running at 425x8 with these settings changed, all others remain default

Vcore-1.45
NB-1.41

and....son of a, work thread 4 just failed.


I'm never going to get this thing stable aarrgh

Basically my question is, is running at 425mhz fsb detrimental to my system? Will it shorten the life or anything bad like that?
Thanks

A lot of people run at 450, and they're stable. Pretty much your computer won't allow itself to run at dangerous levels. If the system becomes unstable, the clocks don't work. Although it's more complicated than that, it's also just as simple as that. I'm running my Q6600 @ 360x9, and it's completely stable. I honestly think the only thing keeping me from going higher is the MB. But your MB has a much better reputation for OC'ing than mine. So go for whatever's stable, and watch out for "holes". Good luck, and keep us posted!

Problem is I can't get it stable at 3.4 using a x8 or x9 multi and the equivalent combos of fsb.
argh.

It shouldn't shorten the life of your system unless you are applying more volts to your northbridge. Also, there is such thing as using too high of a FSB. You could hit a FSB wall with your motherboard but I wouldn't expect that until around at least 475FSB with your motherboard. I would suggest reading up some more on you're DFI P35 DK as it has hundreds of options to play around with and from what I have read it takes a lot of tweaking to get it overclocking well.

I'm not completely sure how DFI's BIOS is, but on mine, I have to set all my voltages to auto to start off. Just inch your way up. Start at 266x9 and just go a little at a time. Once again, I don't know how your BIOS looks, but mine automatically tells me what my memory settings are based on my FSB clock, and I look at what evens out to 800MHz. Those are the most stable clocks for my system. Does that make sense?

I can OC to 3ghz fine by just upping the FSB to 333x9 and leaving everything else at stock.

It's getting stable at 3.4 that is proving to be very difficult and time consuming. I'm changing one voltage one notch each time...never more than that.

My board must be very picky in terms of OC tweaking haha.

Yeah, I'm at the highest stable I could find on my board, and I'm only at 3.24, but that's fine for me. I think with your board you could do better, though. You might be hitting a hole. Try to push past it and see if that works. You also might want to add a little extra cooling to your NB.

I've been told my NB should be fine up to 1.51v...so i'm not too considered at 1.41 but i may look into something later. I'd just like to find a stable clock at 3.4...4 minutes into prime95, almost a record haha.

EDIT**
Should I consider one of those obnoxious "So and so program has encountered a problem and must close" as a failure for prime95? It just did that but none of the tests had actually failed...

Well I are you leaving you ram and CPU linked when you are OC'ing. If so i would unlink them and OC them individually. Might help you find which part is causing the errors. Also sometimes chips have a limit. Just keep trying to tweak the system to find the stability point.
