Opteron 185 overclocking voltages and FSB?

[wingless]

I just bought an Opty 185 to keep my s939 system alive until 2008. I currently have it @ 2875mhz(250x11.5) on a 250mhz FSB and 1.35vcore. I have DDR500 ram that operates natively at 250fsb which is why I've chosen that speed to start clocking at. My ultimate goal is a clock over 3.0GHZ (trying to get 3.2 GHZ actually).

What kind of success have yall had with the 185 or other opterons and especially what FSB and Vcore are you running at? Also do you mess with the LDT or chipset voltage on your NF4 Ultra boards?

Specs:
Opty 185 @ 2875mhz (250x11.5) 1.35vcore
Mushkin DDR500 @ 250mhz 2.9v
DFI Lanparty NF4 SLI-DR Expert UT (NF4 @ 1.59v)
1xMSI 7900GT-HD
22" Sceptre X22 Gamer (POS, dont buy one unless you use HDMI like me)
Seasonic M12 700watt PSU
5xHDDs = ~480GB
1xDVD-RW

Did i leave any info out?

PS: I bought a Vigor MonsoonII Thermal Electric cooler that I have yet to install. It requires taking the mobo out and mounting all this silliness to help handle it's enormous weight. Anyways I've yet to try OC'ing with it and I'm currently just running a big ass Zalman (I forget the model at the moment) but it seems to still cool very well. At load I'm only at 45c with this current overclock.

My FX-60 (same chip) runs @ 13x233=3Ghz with the stock voltage. So far so good. I bet it has more but I haven't tried since I am still using the stock cooler.

Nice overclock with the stock voltages. I'll see what I can push along those lines.

Really I'm asking all of this to see if anybody knows the optimal voltage for a 3.2Ghz overclock. The Opteron has a much different voltage window than my old X2 4200+. Too little voltage and it wont boot, too much and it wont be stable. I'll try 1.4v with 250mhz@13x to see how stable that is and work from there.

I have overclocked 4 Toledo cores, some capable of 2.9 and 3.0 GHz. My problem was the heat on all of them, when pushed to and past 2.8 GHz using the stock AMD heatpipe coolers. I did short out the thermistor to enable max fan speed. That helps. What are your temps like at 3GHz, and your room temp?

If he installs his TEC cooler, heat should not be an issue. I am running a Titan Amanda which is the same as his Monsoon II, and it does the trick nicely.

I should say the heat problem I had was only when running dual Orthos in a stress test. In normal use, I never see temps anywhere near what dual Orthos does. Even playing BF2, temps were 10 degrees cooler than dual Orthos. Also, my computer room can get rather warm, like 85 degrees F. My present cooler is third from the top in this Frosty Tech chart.

i think i might hold the highest amd clock on this forum.

Maybe... unless someone on phase kicked my butt. but i dont think it would be by much:

But it was only a 175. But it would eat FX-62's for breakfast.

Sorry that heat sink is a piece of junk. The Ultra120 EXtreme lapped, and base moded for a more secure mount will eat that for breakfast/lunch/dinner.

So no, i dont recomend this cooler to the op. It uses more electricity for crappy performance. And you can get better on AIR with a single FAN.

And lets not get into the concept of TEC's. Because This is perfect example of the WRONG way to apply TEC in cooling.

Another WRONG way is the COOLIT Freezone. <--- if you have the budget for this PM me. I'll point you to a much better custom waterkit.
