Overclocking Ground Rules

Overclocking is a very big subject, so we really need to define where our Overclocking Guide is heading. We do not believe, at present, that AnandTech readers really want Buyer's Guides for phase-change cooling, water cooling, and other cooling techniques that change by the minute and are used in high-end overclocking. Instead, we have decided to concentrate on the best components that you can buy for overclocking on air with a decent Heat Sink/Fan (HSF). This could change in the future if other cooling techniques go mainstream, but for now, our Overclocking Guide will recommend components for an air-cooled system. Of course, if you do use water or phase-change, or other exotic cooling solutions, you could get even better performance from the components that we will recommend.

While board mods are also common in high-end overclocking - to extend memory voltage in particular - we will not be recommending board mods that will void your warranty. If we know of a board mod that is commonly used, we might mention it, but that is not the purpose of the AnandTech Overclocking Buyer's Guide. We will be recommending components that you can buy, which have proven to provide significant overclocking capabilities at stock.

If you are interesting in finding out more about the extreme end, there are plenty of places on the web that cater to extreme overclockers, with widely varying degrees of success. You can go to sites like the Forum at www.xtremesystems.org and see comments from names like Macci, OPPainter or Fugger who appear routinely at the top of the charts for 3Dmark and Aquamark3. You'll find discussions of phase-change cooling and maybe even liquid nitrogen testing. The extreme high end is as much black magic as technology, and what works almost changes by the minute. We'll leave that arena to sites that already do it well.

What we would like to do well in the overclocking area at AnandTech is to recommend components from comparative testing and experience that can give you a much better than average overclocking experience without you having to become an expert with a soldering iron - or invest in a refrigerated computer case that costs more by itself than our High-End system. No one seems to be doing a good job in this area, and we want AnandTech to become a dependable resource for overclocking component recommendations.

Performance or Value

There are really two reasons to overclock. The first is to reach the absolute top performance levels possible with computer components. The second is to get superb value from your components - to make a sow's ear into a silk purse, so to speak. While this is impossible as the saying goes, in the computer arena, it is not only possible, it is pretty easy to do.

Since these two overclocking areas are often at odds with each other, we could find no really good way to bridge the gap. For that reason, you will see two different recommendations for many of our choices - performance and value. You can expect our Performance selection to reach the highest overclocking levels that you can reach. The Value choice will give you incredible overclocking performance for the money - bang for the buck.

Some components lend themselves to overclocking better than others. Processors, Motherboards, Video Cards, and Memory are targets for most overclockers. So, we've concentrated our efforts on these components. While Hard Drives are not normally modified to perform better, they do have an impact on final system performance and, perhaps more important for the overclocker, they can sometimes limit or enhance the ability of a system to overclock. For those reasons, we will also be recommending Hard Drives in this Overclocking Buyer's Guide. The Case/Power Supply can also influence overclocking results as a result of more efficient cooling from the case or stable, high-output power from the power supply, so these components are also included.

The rest of the system components like Monitors, Optical Storage, and Input Devices are not so easily overclocked, and we will not devote attention to these components in our Overclocking Guide. Since overclocking can run the gamut from value systems to high-end, it is also almost impossible to second-guess what an overclocker might be looking for in a monitor, optical storage, sound card, speakers, LAN, keyboard and mouse. We suggest that you refer to other AnandTech Buyer's Guides for more information on our recommendations for those components.

In the end, we will summarize the recommendations in the Overclockers Buyer's Guides in four areas - Overclocking Performance, OC Performance Alternate, Overclocking Value, and OC Value Alternate. You will see quite a spread between these four systems, but they all represent the best of overclocking - from top overclocking performance on one end to the best overclocking performance that we could find for the money you would spend at the other end of the spectrum.

    It does say the price. Read from the top of the page:

    AGP Overclocking Recommendation: eVGA 256MB GeForce 6800 GT
    Price: $389 shipped

    BTW FX53 is a good choice at overclocking. Keep in mind this is with air. But if you utilize other forms of cooling the FX will go even higher, approaching 3GHz with proper cooling (see THG's review). This makes it one FX58. That is absolutely a grand overclock, seeing that FX58 speeds will not be here for another year or so.

    #4: Did you read Anandtech's article on breaking the overclocking lock? Almost all companies have broken it. It is very possible to reach those speeds with the stock HSF.

    Why isn't the 6800 GT card in the price list on that page? Or am I missing it somehow?

    I think recommending an Athlon FX for overclocking is a joke. Those things do not even manage a 5% overclock, and their real world performance is only close to a P4 at 3.4 GHZ, as gaming at 640x480 is not very common among people spending this kind of money. And at a realistic setting of 1600x1200 and 4xFSAA, the CPU is not really the bottleneck in todays games. When you do encoding, where CPU speed does matter in the real world, the P4 is head and shoulders above Athlon FX.

    How about a VALUE OC DDR section? Paying $300+ for 5-10% performance increase over ~$150 regular DDR is a waste, imho.
  • Zebo - Tuesday, July 27, 2004 - link

    Peferformance
    ------------
    1. 2.8 P4C to 3.6 $180
    2. A64 3200 to 2.5 $223

    Value
    --------
    1. Duron 1.8 to 2.4 $44
    2. Mobile XP to 2.6 $89

    :)

    Wow recommending a P4C over a moblie barton in the value section.Twice the price for roughly the same OC performance I don't get it. It's the inverse of price to performance. must be an error is all I can imagine.

    Then recommending a Socket 775 presshot. Lets see this 3.8- 4GHZ OC with stock HSF. I don't think so. Then the overclock lock issues which hav'nt been settled, have they? My understanding is 10% over stock FSB, yeilding about 3.4 Ghz far from 4ghz, the system crashes!! What kind of overclockers choice is that?

  • chuwawa - Tuesday, July 27, 2004 - link

    Perhaps it's time to start recommending the Athlon64 3000+ for the value OC alternative.

    This is a great guide for overclocking, although I believe that there needs to be some more acutal testing with the 755 and 939 sockets to give us a better picture of how they perform. It is especially difficult when PCIxpress and ddr2 aren't widely available yet.

    If anyone else has some REAL data on overclocking these new platforms, I would like to see those posts.

    Currently I am making a heat sink out of synthetic Diamond (better heat transfer than copper and silver by 2x) and will be testing it on the FX system. If there are any other reccommendations I would be more than happy to hear them.
  • expletive - Tuesday, July 27, 2004 - link

    I would cast a vote for the A64 3500+. If it can reach 2.6 like an FX53 at half the price that's tough to beat.

    The 3500+ is currently retailing for $390 shipped online. I know thats not quite a 'value' but to get FX53 gaming performance for half the price, that can't be denied....
