Kingston KHX8500D2K2/1G


The Kingston Hyper X is a dynamite performer, and frankly it would have been a top recommendation except for the fact Kingston provided a 1GB kit instead of the 2GB kit we tested for every other brand in this Buying Guide. You might ask why this matters?

Smaller capacity DIMMs usually clock higher than higher capacity memory, so the fact Kingston matches our leader Mushkin at the top does not mean a Kingston 2GB kit would perform the same. When comparing memory performance make sure you compare the same size DIMMs if you want to be sure you are choosing the best. Still, the Kingston is an excellent performer, and the 1GB kit is just $226. If 1 GB is enough memory for you, this 1GB kit would be a great choice.

Mushkin XP2-8000 Redline


It has been a while since we have reviewed a Mushkin Redline kit, and we were certainly impressed when we looked at the last Mushkin Redline kit for DDR. The 2GB Mushkin Redline kit turned in the highest overclock we have seen with any DDR2 memory at 1116. Mushkin also managed to reach the timings of the best high-performance DDR2 tested in this roundup - but generally at a lower voltage than others here. This is a winning combination, and you will likely be very happy if you choose the Mushkin 2GB Redline kit for your new Core 2 Duo computer.

OCZ PC2-8000 Platinum EL


We gave OCZ the Gold Editors Choice award when we first tested this dynamite OCZ PC-2-8000 Platinum 2GB kit last March. The OCZ is still one of the best performers we have tested in DDR2 memory, but it now has some company from Corsair and Mushkin. If you want the best DDR2 you can buy, then one of these three will fit your needs.

Comparing High-Performance Memory

It is no accident that all six of our high-performance memory kits for Core 2 Duo are based on Micron memory chips. Micron currently produces what are arguably the fastest DDR2 memory chips available. Using Micron memory chips is also the reason all six kits costs between $400 and $450 for the 2GB kit. Each manufacturer has their own binning (speed sorting) techniques, they choose or develop their PCB, and they also may have very unique customized SPD programming. Despite these differences, the performance of all six 2GB kits are more similar than not.

Three of the six memories stand out for better timings and/or lower voltages at each tested speed. The OCZ PC2-8000 Platinum EL has been highly praised in the past. It is now joined by the Corsair CM2X1024-8500C5 and the Mushkin Redline XP2-8000 as the top-performing DDR2 memory you can buy. Corsair, Mushkin, and OCZ have all three done an exemplary job in the manufacture of these 2GB kits.

In fairness the performance differences between any of these six kits is very small, and you can select any of the six based on the best pricing - confident you will get great performance from your new DDR2 memory. None of these memories come cheap, and many will find $400 to $450 for 2GB of DDR2 memory too much for their new Core 2 Duo system.

If you are in that group looking for value, you will want to take a close look at our test results with a group of seven value priced 2GB kits beginning on the next page. These 2GB kits, ranging from $117 to $170 for the 2GB kit, provide much better value on the Core 2 Duo platform than we first imagined. You will likely be pleasantly surprised at the performance you can get in this value DDR2 segment.

    Great article!!!

    Really waiting for the nforce 5 series (to be mature too).

    Hey
    on the review here it says that the 975xbx can support ddr2 800MHz memory speeds, but anywhere else that I've checked, claims that the board only supports speeds upto 667MHz. Can the board take 800MHz out of the box? or will I have to mess around with it to accept the RAM?
    thanks a lot

    I hope u still have your mushkin XP2-8000 (redline) and never sent it back.

    Here is my hardware.
    --------------------
    P5N32-SLI SE Deluxe / P5B Deluxe.
    Asus Silent tower CPU cooler.
    E6600 Processor.
    2x1GB Mushkin Redline DDR2 1000Mhz / 2x1GB OCZ Platnium 800MHZ
    2x 150GB Raptors,
    1x Seagate 300GB Drive,
    Powerstream 600Watt PSU
    2x EVGA 7950GX2
    Coolermaster Stacker.
    Plexter SATA 755 Drive
    Liteon IDE drive
    Mitsumi Floppy Drive
    Creative Labs X-Fi Extreme gamer.


    Here is my problem..

    P5N32 SLI SE DELUXE

    I put 2 sticks of ram in the system with the video card will not post. I have to remove one stick of ram and leave one stick in B1 or B2. It will not boot from a cleared bios with a stick in A1 or A2. I then have to go in the bios and set the memory below or at 800Mhz for it to post with 2 sticks of ram in it. Even then when I put the two sticks in and go to the bios it shows only 1024MB or system ram. But the post screen clearly shows 2048. There is nothing wrong with this memory. It ran fine with the P5B motherboard.

    When using the OCZ it posts no problem but again shows 2048MB at post and in bios and the OS only shows 1024MB Avalible.

    Asus Tech support is the worst in the world. They instantly tell you its a faulty board this and that. But its not its the bios I am 100% sure it is.

    Could you Anandtech please setup a test bed with the 0121 bios and try it. If it has no issue could you please try 0204 revision and then tell me. I have the same motherboard revision as you show in the picture.

    Thanks in advance.

    I see more and more older boards with Core 2 Duo support. Such as the Asus P5PE-VM which is 865G, AGP, and DDR400. I am very curious how performance is hit using the older chipset. These boards are great for folks who do not want to toss their RAM, video card, etc unless there is a huge difference.

    Thanks for the great writeup.

    The article mentions these will be coming out soon for socket 775/Conroe. Anyone know when? I've been surfing around for hours trying to find info on it. I know NVidia has made the NForce 500s for Intel but none of the board manufacturers lists any info at all.

    Just trying to decide if I should go ahead and get the ASUS P5N32-SLI Deluxe (I want to run SLI) or if it's only a short wait for something better.. !

    Thanks

    Thanks for the great review.
    I was going back and referencing some information from it today and noticed that in the P5W-DH Deluxe Basic Features table, you have the number of IDE ports listed incorrectly as one. There are actually two ports, one provided by the JMicron JMB363, and the other from the ICH7R southbridge. I got that info from the Asus website.

    Is that the other IDE port over below the last PCI port?! If so, that's rediculous.
    But this is one of very few Core 2 Duo supporting motherboards that I've seen that have 2 IDE ports, so I might just have to get it.

    Gary, I look forward to the upcoming review you mentioned earlier in these comments of the Biostar motherboard with the VIA VT6410 controller. IDE performance continues to be important to me, and will for quite some time with the investment I've already made in hard drives. NEVER AGAIN will I get burned by an under-reviewed, underperfoming chip like the IT8212F!

    Thanks again for your quality reviews.

    I am very impressed with this guide, looks like a lot of hard work went into it!

    I have a question though. I am using the release of Conroe as an excuse to build a whole new system. After reading your guide in addition to others, I've decided on the E6700 and the DFI board (as I don't plan on OCing much, if at all).

    However, the video card I had chosen is a X1900XTX, as I have read many bad reviews on the 7900 series having assorted problems with heat and other issues.

    Now, having read this, I see that Conroe isn't playing nice with my chosen vid card, possibly due to driver issues. My question: Have you guys received any word from ATI, or has a new driver been pushed out yet that brings its performance up to par where it should be? There's absolutely no reason the Nvidia card should be blowing it away, especially on HL2 and other typically ATI friendly games.

    If not, should I forget the ATI card and take a chance on one of the Nvidia cards, or simply go with the ATI card and hope they push out new drivers soon? The AMD/ATI aquisition further complicates the situation... I somehow doubt they'd do any favors for intel based systems.

    No edit button :(

    I meant a X1900XT, not the XTX version. I'll keep my $100, thanks :)

    Sorry, one more quick question. Is the Zalman CNPS9500 compatible with the Conroe? Reply
