How to disable OVP on Asus SK8N MB?

I may have to move this to another topic, as it may be too far off the original subject. Forgot to mention, if you have many processors laying around, you may want to remove the IHS. It dropped my under load temperature by 10C on my Opteron 144. I have pictures of your FX-51 with it's IHS removed and it looks nearly identical. I was hoping the unlocked multiplier mod could be discovered by a few brave OCers by doing the mod. It is really hard to do - I had to use sandpaper and emery cloth to file a razor blade to about 1/2- 1/4 of usual thickness, then apply pressure all the way around the perimeter of the IHS seal about 2mm inward slicing the adhesive material. You have to start on the corners and hopefully get it cut and slide all the way around. Don't do ANY prying, regardless of what others have said. It took 2 days of very careful cutting and pushing before it came off! May enable you a higher OC if you can't up the OVP. Also we can measure resistance values on the processor to find what they changed at the factory, although it appears 4 value capacitors are lined all the way around the CPU core, with 2 locked in blue epoxy. Seems the blue are the processor multiplier/ default frequency select is my guess. I'd be curious to get my hands on a 244 to see what the difference is as well, could save a bundle this way converting 1x to 2x! They do have the 940pins supported for 3 more years if I remember right, way past the end of the 939pin, so we could benefit from this information for some time.

The other chip you may want to get your hands on, which may outperform the FX-53 in overclocking, is the Model 146 HE $417 off AMD's website. I think www.monarchcomputer.com is the only store that has an HE in stock, and they appear to only have the 246HE at $709. Otherwise, a search on google will yield OSK146ATBOX under $500, but not in stock for at least 2wks. http://www.computerhq.com/AMD_OPTERO...id-462024.html ships to Denmark $556.78 US Dollars total. It is the low power 55Watt 2ghz Opteron (89W standard), which, based on previous AMD low-power models (such as the mobile XP), can be taken much higher than the standard models. I have gotten my Opteron144 up to 130W or so at 2.3ghz. In comparison, this HE processor would be at 80W at 2.55ghz, or usable with the standard heatsink and fan (in theory) even at 116W at 3ghz! 170W at 3.5ghz 249W at 4ghz estimated ... I believe your condensor will do 300 or 400W of heat reduction or higher, so imagine the possibilities!! -Matt
