overclocking an opteron with no HT control?

Hello, I decided to check out the overclocking potential of my opteron last night but found that the motherbaord (MSI RD480) has very little in the way of HT options: either auto (5x) or 200Mhz (1x)

Is it even worth overclocking with such limited options? any overclock would need to be done with the 1x option so the HTT speed will only be 200 + whatever extra I get out of the CPU.

HTT doesnt have a very big effect on real world speed;

bench it, overclock it, and bench it again.

Keep whichever setting is fastest.

The overclocked setting will definatley be fastest, regardless of the htt bus freq.

You can always lower the cpu multi, giving you a higher htt for the same clock, but i wouldnt bother.

Still wouldnt work, the htt freq would max out way before the htt got close to 1000.

The board has a 350 limit on HTT/FSB.

I did a quick test last night, a 45mhz overclock with the HT multi set to 1x and ran 1m superpi, it finished 2 seconds quicker than stock settings. Hardly an exhaustive test I know but once I get round to downloading prime and sandra I'll give it a real testing session.

Thanks for all your input.

It is possible to go over the 2000MHz htt "limit" most boards won't go far past it, but others will. Its worth a shot.

There might be some hidden options? Forgot what you have to press...

Maybe AUTO adjusts the speed automatically when overclocking?

Maybe look for some reviews to find out some more info.

Checked quite a few reviews but few go into detail about overclocking. Only one review went into detail about the overclocking options which is where I got the 5x/1x info from.

If you use a lot of i/o devices and have a lot pci cards ldt x 1 is unacceptable.
