athlon 64 in pavillion
my aunt jill is wanting me to overclock her new hp pavillion. its got
an amd athlon 64 in it. is there any way to overclock it without taking it apart? |

THe factory BIOS will probably not allow it to be overclocked. That means you'll have to flash it to a hacked version (if you can find one) and void your warranty. Also, in my experience, off-the-shelf models like HP and Gateway, etc. are usually crippled by crappy memory and slow hard drives, not the CPU. Of course, this may have changed. THe HPs I deal with are all several years old. -Dylan C |

If the motherboard uses an Nvidia chipset, then there is a chance you can overclock it with the Clockgen program from www.cpuid.com . That is called "Windows overclocking", because you do it while you are in Windows, rather than in the BIOS. It is an option for people who have a crappy (fixed) BIOS. The Nvidia chipsets (Nforce3, Nforce4), I believe, do clock synthesis in the chipset. That is why it is possible for the author of Clockgen to write a generic module for all Nforce3 or Nforce4 motherboards. For other chipset makers, like maybe VIA or SIS, the clock signals come from a clock generator chip, and that must be custom programmed. There are a thousand different part numbers of clock generator chips used on motherboards, and the odds that the Clockgen program knows about them, is very small. Thus, if a non-Nforce chipset is used, then Jill is stuck. A second program of some use, is A64tweaker. A64tweaker allows changing memory settings, so you can downclock the memory to compensate for the upclock from Clockgen. http://www.xtremesystems.org/forums/...t=37345&page=1 http://www.cranox.com/Software/A64-T...r_V0.6beta.zip (Picture of the A64tweaker panel) http://www.overclocking.es/modules/w...a64tweaker.jpg Now, I don't know if there is a way to change the Hypertransport multiplier on the fly or not. Normally, HT would be 5 x 200. The 200 is the CPU clock, which is the thing to be changed with the Clockgen program. HT is limited to 1000MHz, so if the clock is raised above 200, then the HT multiplier needs to be dropped. If there is no mechanism to drop it, then the overclock may be limited to 10% or 20% or so. I don't really know how far HT will go on a processor, before the wheels fall off. With some chipsets, like I think ATI, it is possible that the chipset end of the HT link, can clock quite high. But the processor end of the HT link may be the limiting end. The only other thing missing for Jill, is voltage bumping, for Vdimm or for Vcore. An HP may not have a setting like that in it, but check the BIOS anyway. While it is possible to change Vcore, with a gnarly hardware mod (soldering), we don't want to void the warranty :-) If the only control you had was the main CPU clock (200MHz), and you didn't have access to anything else, you might squeeze 10% to 20% out of it, before it crashed. You really need access to a few different things, to do a better job of overclocking. An enthusiast motherboard is what you want for a job like this. When doing overclocking experiments, you should use a different boot drive. Bring a spare drive. Disconnect Jill's boot drive. Install the spare. Install Windows on it, your copy of Clockgen, a copy of Prime95 from mersenne.org (for testing). Sometimes, when doing overclocking experiments, the boot disk or the registry stored on it, gets corrupted, and the OS can effectively be lost to the user. Using a spare boot disk, avoids this fate. Test with Prime95 (use the torture test option in the menu). Don't put the original boot drive back in the computer, until Prime95 can run for four hours or more, error free. If you overclock to a frequency of "X", turn the clock down to 0.95*X before giving the computer back to Jill. The small margin, is intended to help the computer continue to run well on a hot day. I call that the "everyday overclock" frequency for my computer. The computer I am typing on, is overclocked from 2.8GHz to 3.2GHz (yawn!), but that is all I could manage with complete stability. The computer has not crashed once with that modest overclock. Paul |

Thats good advice. Corrupting your boot disk isn't exactly common, but it does happen. I know I've done once or twice. Those were bad days. Test with Prime95 (use the torture test option in the menu). Don't put the original boot drive back in the computer, until Prime95 can run for four hours or more, error free. If you overclock to a frequency of "X", turn the clock down to 0.95*X before giving the computer back to Jill. The small margin, is intended to help the computer continue to run well on a hot day. Its also important to make sure that she cleans the dust out on a regular basis. Once you start increasing the voltage, you start working in the upper end of the CPU's temperature range. Dust in your cooler makes temps creep up even higher and could cause a thermal failure. -Dylan C |
