I don't think there's a huge difference in FSB OCing and pure multi. The pro of going FSB is to squeeze out every little MHz you can. So 4500mhz vs 4572MHz, etc. Another is to try to get a stable overclock that couldn't be reached with pure multi. Otherwise FSB OCing is for saying you have a nice chip/mobo capable of high FSB. Use the combination that will give you the highest but stable OCs.

Me wanna see proof of that.

Even with my recorded FSB run, I gotta say 350 is the max I can get to boot. You should know how different booting is to being stable.

FSB has the advantage of a bit lower latency than on the memory. Nothing dramatic.

As kgskeufnxjsBOY said, biggrin.gif just to get the highest OC under all limits is it worth the hassle. I'm talking less than a 100MHz more really.

i'll post a pic after I've messed around with everything. Mine will not boot up at 350 tongue.gif just tried.

I'm mainly aiming for the "lower" temperature part of fsb overclock and trying to hit that 5.0 Ghz. However, from the looks of it 332 is the limit which puts me just shy of 5. The only thing I can do is add more voltage which I can not since I'm at 1.48v and any higher would push my cooling system too far. (not to mention I have to do this again during summer lol)


anyways. do you have any tip for higher fsb stabalization- aka getting it to boot?

Bus vs multi isn't going to make that much of a difference temperature wise.

so it seems that my temp is a bit high. sigh. Freaking 1c. I think i'll let it slide for the time being since it is a stress test. Will have to monitor it when I render though. Now I'm to have to wonder how i'm going to do long term stress test cause of temp............

What is your Multi set to? That shot says 21 whch would put you int the near 7Gz range.

its at 15. I turned on my power saves to see if that would do anything to drop the stability.

it says it has passed but.... that result doesn't look like it passed... or am I missing something.

Can someone please elaborate what exactly is the point in changing the REFCLK from stock?
There are no locked AM3+ consumer CPUs and I don´t think the few AM3+ Opterons are too popular wink.gif

The 2x 10.4GB/s HTT bandwidth available between the CPU and the chipset can be a limitation, but basically only on paper.
While two x16 Gen 2.0 links require 16GB/s of bandwidth in total, the difference in performance is non-existent even if the bandwidth is capped to half (x16 to x8, ~3%).

The REFCLK specifications are extremely strict, and violating them by changing the frequency from default can case all kinds of issues.
Even when the motherboard is using an external Pll, only the REFCLK and PCI-E clock are generated by the external Pll. All of the other frequencies are generated by the southbridge, which also happens to run of the REFCLK. When you alter the REFCLK, you are throwing everything else out of whack too.
