AMD Processors Maximum Bus speeds

[Kei]

Recently I've been wondering exactly how high others have been able to take an AMD Processor Bus speed.

I'm not concerned with how high the resulting processor speed was but just the highest bus speed you've been able to do. I know AMD processors have had some trouble reaching nosebleed regions in bus speed but there are some of us who can indeed reach abnormal speeds.

Please list your processor model and the maximum HT Bus speed that you've been able to hit with that processor. This goes for Quads, Tris, Duals, and Single core processors so fire away! Screen shots would be great if possible

I'll start it off with immediate shock and awe (though I've still not found the actual max yet)...
========================================================================

AMD Phenom II X4 920
HT Bus speed 372Mhz
ASUS M3A32-MVP Deluxe
Xigmatek HDT S-1283 (Scythe 110cfm fan restricted to ~30cfm for absolute silence)

Yes this was with all four cores enabled not a paired down single core run with crazy voltage or exotic cooling. I ran this bus speed at 10x multiplier but don't have enough voltage available to keep it stable at that speed of 3.72Ghz with a limit of 1.50v.

I am running something similar to this here. All of the scores should have HT speeds, just check there. http://forums.techpowerup.com/showthread.php?t=36777

I actually just was asking a question like this recently. Here. I can get stable at up to 276mhz, but I run it at 266 x 11.5. I cannot get this over 276 no matter what I do. With my old K8 on the same board, I could hit near 310mhz stable.

As I mentioned, I have varying success on max reference clock with different memory dividers, which is somewhat strange. It certainly is good, however, to see that the Phenom 2 can handle greater bus speeds.

Can I ask what voltage you put through the northbridge/chipset to achieve that? Also, does adding voltage to the HTT or HTR buses help any? And how high did you manage to achieve on a Phenom I?

On my Phenom I 9850BE I went to 266Mhz stable maybe sneaked 1Mhz past that but that was it no matter what I did it seemed.

Really it was the same way on this processor until a few days ago it just unleashed everything and now I have no idea what the actual limit is I just quit at 372Mhz.

Northbridge voltage was 1.4566v just like the processor voltage was for almost all of the testing until I hit the final speed where I bumped the voltage just a tick to be safe.

HT voltage was set at 1.30v but I don't even know if it actually needed that I just put it there so I could just worry about the Bus speed instead of anything else and I'd tweak it if I needed too, but never had to. It went crazy high without changing it to that setting just as well.

The highest I've seen on Phenom I was 291Mhz done by a friend Viscarious who's a member here still floating around in the shadows lately.

I believe if serious tweaking was done you could probably go higher still on Phenom I, but I highly doubt that you could achieve what I've done on Phenom II especially using just air cooling like I am right now.

Well I forgot about my other Phenom I chip which hit 275Mhz (Phenom 9500) whereas the Phenom 9850BE hit 266Mhz on this board.

Oh, if you want to run something like I am, except for HT, feel free to steal my design. Just quote me, copy, paste and viola, you have a format. All you would have to do is change out the urls and turn clock speed to HT.
