Need help from Opteron 165/170 owners!

[El Jimben]

I was wondering if those with either of the above chips could post what overclocks they're managing along, the voltage required, if it's a 165 or a 170 and the stepping of their CPU. I only ask as I'm not happy at 'only' getting 2.7Ghz from my x2 3800 so I was thinking of getting one

 

[El Jimben]

I've had a good google and had a look at a lot of other forums but I wanted info from recent buyers.

 

[El Jimben]

Probably but I got the overclocking bug now and I'm not content with what I already have! If it does more than 2.7GHz with less voltage I'll be happy, as mines running at about 1.6v atm

 

[El Jimben]

I'd probably suggest the latter, the technology will be more refined for one and also if you were thinking about going Conroe, the 6600 etc should be cheaper. Even then you'd still probably get a tidy sum for your Opty judging by your results in the other thread

http://www.xtremesystems.org/forums/showthread.php?t=96900 The same thing basically but with people's results and what cooling and volts they were using.

 

[El Jimben]

A 900MHz overclock isn't bad but I think these chips do require a bit of tinkering to get the max out of them. Voltage and heat obviously isn't your problem so I'd fiddle with the RAM next.

That table shows that 20% out of all of those get to 3GHz and the one I have ordered is 3GHz capable so we shall see, not sure bout the OPs though, as he doesn't give the full stepping. My x2 3800 isn't too shabby so I should be able to get a few quid for it plus I fancied a new overclocking project and I don't need to go Conroe just yet.

I have the same stepping, Opty 170 but I can only get mine to run at 2.67Ghz. That's probably because my mobo (Asus A8R32MVP) will only let me specify a max voltage of 1.4V although according to Asus Probe it's about 1.45V.

At that speed and voltage it's running at about 45 degrees with an Arctic Cooling Freezer Pro hsf.

Anything above this and the PC just locks up or fails to boot

Does your board not have the vcore overvolt option like the Deluxe version does?

 

[El Jimben]

Yes it does but it seems to cause more problems than solutions as the only option it gives is 'overclock vCore' which is an automatic overvolting feature.

Using this feature causes random lock-ups when the going gets tough and the CPU demands more voltage. Keeping it at 1.4 - 1.45V seems to be the most stable option.

The mobo I have is the A8R32MVP Deluxe which has these features but the voltage options are very conservative for high overclocking as far as the CPU is concerned.

You can't have the voltage higher than 1.4v without using the overvolt feature which adds another 0.1v or 0.2v i.e 1.6v total. The only problem with this board as far as I can see is that it doesn't give the extra 0.2v, it's more like 0.15v imo.

Got my 170 in the post today, currently doing 2.8GHz and stock volts, not tried 3GHz yet though. I'm not sure if I did a super amazing job with the AS5 or if there's just far better IHS contact than with my x2 3800 because idle temps are currently 25c and 30c
