Some questions on overclocking
Hi guys. A couple of questions on overclocking...
If you had to pick an AMD64 processor to overclock, which one would you take, and why? I thought an AMD64 939-pin 3000+ Venice core might be good. For that matter, why does a smaller manufacturing die (e.g. 0.9nm) translate to lower heats? If you had to pick a processor from any class to overclock, which one would you take? I read that overclocked AMD Duron 1600 processors beat some AMD XP 3000+ processors... Also, supposing you fry your processor through overclocking, how will AMD know about it to void your warranty? Perhaps through evidence of non-stock thermal grease on the CPU? I also read that you stand a chance of corrupting data on your hard drive through overclocking your CPU. However, if your CPU runs Primetest without any errors, is it safe to assume that your HD data will not be corrupted at all? Related to the above question, as I was planning on overclocking my AMD XP 2500+ Barton soon - the data on my HD and the accuracy of my CPU's computations are critical to my work. Do you recommend not overclocking at all then? Thanks. |

An AMD Athlon64 is a nice processor. If you can choose, look at the
codes. I got this one from the Internet: ADAb3200/b AEP5bAP/b CAAMC 0343WPMW 9775565K3b0501/b 3200: the type AP: the core type (that should be BP for a venice.) 0501: the lower to 0 the better. If you fry your processor, the stock cooler wasn't good enough, and it is always good enough for the default speed. Marc Random Person wrote: Hi guys. A couple of questions on overclocking...

It doesn't always, but generally it is because it allows using lower voltage. If you had to pick a processor from any class to overclock, which one would you take? I read that overclocked AMD Duron 1600 processors beat some AMD XP 3000+ processors... Sure, if you were able to o'c the Duron enough, but apples-to-apples comparison would be to then o'c the XP3000, too... and still it depends on the specific use. For many uses, the XP3000 at stock speed may still be faster, particular real-world uses instead of synthetic benchmarks. Also, supposing you fry your processor through overclocking, Don't do that. Overclocking is not some kind of "reckless" activity, it is simply using a CPU that produces more heat... a bit like running a P4 Prescott instead of an Athlon 64. You have to have sufficient cooling for any particular level of heat. how will AMD know about it to void your warranty? They will probably replace it anyway because they're looking at keeping goodwill towards customers, BUT it might be considered illegal to void your warranty and then seek replacement. Generally though, if you let your CPU run too hot, it matters not if you overclocked it, you voided your warranty. The one exception might be if you had the AMD-recommended chassis configuration with (expected) typical ambient room temps and then the AMD retail fan itself failed, stopped spinning. Perhaps through evidence of non-stock thermal grease on the CPU? Why would you buy a retail CPU for overclocking? To get the significant increases you're considering (similar to o'c a Duron till it's faster than an Xp3000), you need a better heatsink. Overclocking is not just about raising a clock speed, it's about having entire system that can accomodate that raised clock speed in every way. Yes, if you left 3rd party grease all over the CPU they might noticed and void your warranty, but if you cleaned it all off (for example, using detergent and a toothbrush under running water) they'd probably not say a thing. Even so, that is not something you should do, you take the warranty into your own hands and void it by deviating from any and every stock part of use... including 3rd party compound/grease. They can only realistically warranty what they know for certain to be a valid configuration. I also read that you stand a chance of corrupting data on your hard drive through overclocking your CPU. However, if your CPU runs Primetest without any errors, Prime 95's Torture Test. That checks for CPU errors alone. is it safe to assume that your HD data will not be corrupted at all? Yes and No, it only "greatly" minimizes the chances that the CPU itself is instable, it does nothing to ensure a higher front side bus, motherboard bridge bus, or memory itself is still stable. You'd need to check any and all things that have had their operational speed changed. Generally speaking though, if your bus speeds are still in spec, or rather close still, AND Prime95's Torture Test runs without errors, there should be no data loss from these factors alone. However, if the data integrity is of utmost importance, do not overclock. If the sytem is mission-critical, do not overclock. However, any system with these requirements should be just as extensively tested as an overclocked system would to be qualified for such uses, so ironically enough an overclocker may have a more stable system than a non-overclocker because they've taken atypical steps to check system stability, and rectified any such problems. This is only considering moderate o'c though, not extremes. With extremes, it depends a lot on exactly what you're doing. Related to the above question, as I was planning on overclocking my AMD XP 2500+ Barton soon - the data on my HD and the accuracy of my CPU's computations are critical to my work. Do you recommend not overclocking at all then? Yes, not overclocking it is certainly the best course. The odds are high that you could o'c to at least 2.1GHz and not have problems, but I will not presume you want to play odds with critical calcs or data. However, if the calcs and data are really critical, a system using ECC memory is then the best solution yet most do not have this type except in servers. |

Thanks guys. You really know your stuff! I think I'll keep this system
at stock speeds. |
