Kingston HyperX KHX8500D2K2-4G

Going For 4GB: DDR2-1066 Kit Round-Up
By

Kingston is one of the larger memory vendors and has long offered upgrade kits and enthusiast memory, along with related products such as flash memory devices. When we called for a 4 GB DDR2 memory kit, we received a HyperX kit with two 2 GB DDR2 DIMMs called KHX8500D2K2-4G, from which you can already tell these are PC2-8500 DIMMs (DDR2-1066 speed). The HyperX family is Kingston’s product line for enthusiasts, and there are DDR, DDR2 and DDR3 memory kits available. However, Kingston does not belong to the group of memory vendors that races for maximum clock speeds. This isn’t really a bad thing. In fact, Kingston is actually the only memory company that provides a truly solid technical specification sheet. You can get information on Kingston products on the corporate website www.kingston.com, while there is a microsite to deal with the HyperX line.

Package, Specifications

Believe it or not, we really liked the way Kingston boxed its memory. Both DIMMs fit into an anti-static plastic box with a clear cover, which is sealed with the product specifications. That’s not as fancy as a huge color box, but it’s as much as you really need to box a pair of memory modules. Both DIMMs are inserted in such a way that prospective buyers can examine the product stickers. These tell you about the part number and the voltage specification (2.2 V in the case of our test samples), but they don’t tell you anything about memory latencies. Only CL5-5-5-15 timings are supported, at 1.8 V default voltage or at 2.2 V maximum voltage. The SPD ROM is programmed to run the memory at DDR2-800 speed, 1.8 V and CL5-5-5-15 timings, which are the default values.

When we tried to find the best prices for the Kingston KHX8500 4 GB kit, we instantly found a great deal on shop.kingston.com, where the regular $150 price was discounted to $135—not bad for a 2 x 2 GB memory kit. You may also go for a product version that is based on 4 x 1 GB modules, but the 2 x 2 GB kit we reviewed was temporarily out of stock when we checked.

Overclocking

We started our overclocking attempts at the default DDR2-1066 voltage of 2.2 V, which didn’t take us much further than the default speed. However, a slight increase to 2.3 V helped to reach DDR2-1130 reliably. Any faster speed would result in the system becoming unstable.

Kingston provides an amazingly attractive price for performance within the expected range. If you can live with the fact that it doesn’t overclock much, this product provides an excellent value and receives our Recommended Buy Award.

    Hmm, then this is a really good deal then:

    kingston hyperx for $75 with shipping
    http://www.newegg.com/Product/Product.aspx?Item=N82E16820104060

    But even then, prices in the article seem rather high don't they? Just wait for a rebate on the RAM and get it then, hell OCZ has had a new rebate continually for the last 3 months.

    I don't know about this...

    What with Nehalem, the X58 and DDR3, upgrading DDR2 seems like a cheap and temporary thrill.

    What about this memory kit; I have it and love it...

    http://www.patriotmem.com/products/detailp.jsp?prodline=5&catid=2&prodgroupid=65&id=576&type=1

    Runs rock stable on my 780G based board and this kit can be had for as little as $90. Was there some reason this memory was not included in the tests?

    I use the Kingston mem on 1.066MHz with 4-4-4-12 timings on 2.2V and it is running stable for eight months now. Deffo a go.

    lol I love how DDR2-667 performs within .2% of DDR3-1066 :D 
    For me, DDR2-800 seems like a decent way to go. It can be found online for $60 for a 2x2GB set. I'm just rolling with a basic set of 2x2GB DDR2-800 XMS2 from Corsair. It runs fairly fast and cool; haven't tried overclocking them yet, though.

    They are all overclocked 800mhz ics amnyway so it doesn't matter. You can but pc6400 modules that do 1066 - 1200 with ease these days. Tom should have picked specific ram ic's like micron d9's , promos, and a few other good ones and compared the overclocking that way.

    Good Day

    Wow that could have actually been a useful article if only you had done the test on an AMD system as well...

    I was thinking the exact same thing. I think it's pretty well known, at least here, that you see little difference between DDR frequencies when they're above the Bus speed (for those processors still using the north bridge as a memory controller).

    I would really like to see comparisons between DDR2 memory with a Phenom. I was looking for this the other day and turned up with little direct comparisons of DDR2-800 vs 1066. It'd be a really good article to read, and one that I think Tom's should jump on. It'd also give people a chance to see what an IMC can do and maybe help some people out when they're picking out DDR3 for their Core i7's.

    I think writers @ Toms has to learn what Overclocking percentage means...
    100% overclock is running it twice as fast as spec.
    so running at 106% overclock is more then twice as fast?
    I think their concept of overclocking percentages is mixed up.

    bleh, these are the best high clock ddr2s on the market. guess they don't qualify since they are 1100mhz lolz.

    That isn't the same Kingston ram featured in this article. The timing for that RAM is 7-7-7-20, although it is very affordable. I'm thinking of picking up a set of it myself.

    According to OCZ's own website:
    OCZImportant Note: Due to the width of the heatsink, Flex II memory kits cannot be installed on motherboards that require the modules to be inserted in sockets side by side. A maximum of one Flex II dual channel kit will fit on any motherboard with dual sockets.

    I guess it's a good thing this review was done on an Asus board with staggered memory channels (A->B->A->B). If your motherboard groups your memory channels (like my old Gigabyte and Asus boards, i.e. A->A->B->B) then these modules will be worthless as they will be running in single-channel (cause you couldn't put two modules on the same memory channel). I think this fact alone means they are worthless as performance memory. You'd get better performance out of 667-dual channel if you have a mother board with grouped memory channels.

    there's nothing interesting with memory technologies since before DDR2 came out. now, the FSB and RAMs had catch up with the CPU not like before.
    but there's an interesting comment i've read above. Why not test a quad core with a heavily threaded application, i'm sure there will be big differences in memory/ram speeds.

    ddr2-800 is as fast as it gets with sane fsb400. overclocking higher than fsb 400, ddr2-800 is only usefull untill ddr2-1066, fsb 533.

    And like said before, most ddr2-800 kits go to 1066 with relative ease.

    EVERYTHING above fsb 533/ ddr1066 is useless. Face it, acknowledge it, learn it.

    Daredevils that push their system to 600+fsb do so for a very short of time just to prove that they can. Not many of those and usefulness of these test is debatable.

    While 4 GB of RAM cannot be fully utilized on 32-bit operating systems such as Windows XP windows xp and Windows Vista 32, you’ll still get between 3.3 and 3.7 GB of effective memory capacity.

    Ummm... Am I the only one that knows about PAE???


    Besides the fact that you didn't do all your homework the article was very well written and informative. Thanks
    ~Cheers

    P.S. Next article idea... PAE and how it home users can benefit from it. BTW i do not recommend PAE if you use non-standard devices as it can have issues with drivers.

    PAE stands for Physical Address Extension or something like that :)  basically its a software trick that reminds me of paged memory, I also think that it requires programs that are designed to use PAE in other words no games will make use of it and only a handful of programs make use of the added RAM.

    so... its useless. ok

    I really cant think of a single reason one shouldn't use win xp x64 instead of win xp 32bit- save for 16bit app support (think old dos games, that can be run on dosbox anyway..)

    eodeoso... its useless. ok



    No for some programs it is probably really cool :)  I imagine they use it allot for server type things or large data bases. Please note that I am no expert by any means when it comes to PAE lol
