Microsoft Excel 2007 SP1

Excel can be a very powerful mathematical tool. In this benchmark, we are running a large Monte Carlo simulation on stock pricing data to estimate the riskiness of an investment portfolio.



This benchmark runs entirely in cache, so the results are predictable. Memory bandwidth or latency is not going to make a real difference here.

Photoshop CS4 x64

To measure performance under Photoshop CS4 x64, we turn to the Retouch Artists’ Speed Test macro only with a custom image sized at 4800x3600. The test performs basic photo editing; a few color space conversions, several layer creations, color curve adjustment, 3x image and canvas size adjustments, unsharp mask, and finally a gaussian blur performed on the entire image.



We expected different results in this particular benchmark, but it is one of several applications that responded well to DDR3-1066 C5 settings in single task mode.

Bibble 5.0

We utilize Bibble Labs’ Bibble 5 v2 to convert 50 RAW image files into full size JPEG images with the program’s default settings. This program is fully multithreaded and multi-core aware.



This application responds well to memory bandwidth coupled with improved latencies as we see about a 5% improvement switching from 1066 C7 to 1600 C6.

iTunes 8 x64

We import the album Tommy by The Who to our disk in WAV format. The directory consists of 25 songs totaling 751MB. We then convert this music collection to MP3 format utilizing 320Kbps VBR Highest audio settings or to an AAC format using the iTune Plus option.





Utilizing either transcoding method, iTunes performance remains almost flat regardless of memory type. We notice about a 2% improvement switching from 1066 C7 to 1600 C6.

    1.) The recommended DDR3-1066 Patriot PSD36G1066KH is non-ECC and unbuffered. Will this be an issue for the personal desktop use, mainly for video/audio transcoding/muxing?

    2.) The article does not specify how to achieve the CAS5. Does anyone succeed the CAS5 with this Patriot DDR3-1066 and/or overclocked DDR3-1200?

    3.) Is it possible to achieve the CAS5 with other brand, such as GeIL CAS7 GV36GB1066C7TC or Crucial CT3KIT25664BA1067??

    4.) According to Tom's Hardware, not all the X58 motherboards support CAS5 http://www.tomshardware.com/reviews/cheap-x58-moth...">http://www.tomshardware.com/reviews/cheap-x58-moth...
    so does it mean I cant obtain the ideal performance with the combination of "ASRock X58 Extreme" motherboard with "Patriot PSD36G1066KH" Tweaked-CAS5 DDR3? I really like the Asus P6T SE but the layout of the two (blue) PCI Express 2.0 x16 slots, too close to each other is killing me:(

    Spend the extra money on an SSD rather then faster Memory. Although i would love to see how Tri Channel differs from Dual Channel. ( Same results? )
    And how integrated Graphics differs in memory speed.

    Gary, you obviously get paid by wordcount. Too much waffle. Get to the meat faster.

    And what about this $200 between cheap and expensive DDR3 kits? How about seeing WHERE that $200 could have been spent in OTHER upgrades, ie. CPU or GPU, and running benchmark comparisons against THAT setup vs. the first.

    Otherwise, thanks for running all the tests and creating the data for us to review :-)

    As soon as I looked at the chart on the first page of the article, it was clear that the DDR3-1600 C9 memory would represent the best bang for the buck. It was only marginally higher priced than the DDR3-1066 C7 (and the DDR3-1066 C5 doesn't count as you overclocked the DDR3-1066 C7 for that purpose), and was sure to perform at least as good, and probably better than significantly higher priced DDR3-1333 modules at C8, and almost as good as the DDR3-1333 C7.

    Given that faster memory modules only ever have a negligible effect on real-world performance (unless you are a pirate and spend a lot of time using PAR2 checkers to rebuild damaged files from newsgroups, or WinRAR to then extract the original files, the sort of stuff I certainly won't say I do), then you may as well get the cheapest brand-name memory available. If you're spending in the upper mid-range on your CPU, then go for slightly faster (like the 1600 C9) but still quite cheap memory-modules. The only people who should be getting those top-of-the-range modules or anything close to that price level are those who have already decided on the fastest Core i7 CPU avilable (i7 975 currently), as otherwise they're wasting their money on the wrong bit of hardware.

    I'm more confused than ever... what to buy?

    Putting together a new system...
    Win7 or Vista x64
    i7-920 CPU
    x58 MB
    ATI 4890 video

    Memory? I'd like to go with 6GB (3x2gb), thought I had my choices narrowed down to:
    Opt1: $138 mushkin 6GB(3x2GB) 1333(PC3 10666) Model 998706, Cas6, 6-7-6-18
    Opt2: $175 mushkin 6GB(3x2GB) 1600(PC3 12800) Model 998691. Cas6, 6-7-6-18

    But after reading this article, and your comments... I'm very uncertain....help!

    Given a choice between either DDR3-1333 or 1600 memory with identical timings (6-7-6-18), but a $37 price difference, I'd probably go for the 1333, especially as you have decided on an i7-920. If you want to spend a little more to improve yours sytem performance, the memory speed is the last place to look at to do so. Reply

    I took just the opposite from it - he has a 4980 there - overclockable nicely, is saving quite a bit with lower cpu, and what else can get him another 2,5,7,14 % in framerates, especially minimum in some cases ? I think the higher ram is much better and worth it after seeing this articles results.
    He will OC the 4890 and the cpu likely, so that fast ram will give it that great finisging kick and make it awesome.
    Spend the $37 and be happy - definitely.

    G.Skill 1.5-1.6v 1333 Cas 8-8-8-21 = 65
    Crucial 1.8v 1333 Cas 6-6-6-20 = 64 (sold out right now)

    OCZ 1.9v 1600 Cas 7-7-7-24 = 54 (after 20 mail in rebate)
    Patriot 1.9v 1600 Cas 7-7-7-20 = 95 (free shipping)
    Patriot 2.0v 1600 Cas 7-7-7-20 = 100 (Green, which I like)

    So basically, it really ONLY makes sense to buy the OCZ 1600 Cas 7 for 54 bucks, why pay more for less?!!!
