Value DDR2
Not everyone is prepared to pay $450 for the very best DDR2. Without comparing performance of lower-priced DDR2 it is also not possible to recommend whether high-performance DDR2 represents a good value for you. Looking at what was available in the market, we compiled a list of modules that appeared to be a representative cross-section of the 2GB kit value segment. With prices ranging from around $120 to $180 for a 2GB kit, these DDR2 modules are less than half the price of our high-performance selections.
The real question, of course, is where you can take these low-cost DDR DIMMs. We ran all the DIMMs at the highest DDR2 speeds and the fastest memory timings we could achieve on a standard Core 2 Duo test platform. The results were truly surprising.
A-Data Vitesta DDR2-5300
A-Data is one of the largest memory application suppliers in the world and their Vitesta DDR2-533 kit performed extremely well in our testing from both a timing and voltage aspect. The quality of the heat spreaders and memory PCB is excellent..
Corsair Value Select DDR2-667
Corsair was able to provide us their ValueSelect 2GB kit. Although Corsair is mainly known for their XMS series of high performance memories they also provide a very good price to performance offering in their ValueSelect series. While the modules do not include any heat spreaders, we did not notice any thermal issues during our testing that required the use of higher voltages to reach our reported numbers.
Kingston Value Ram DDR2-667
Kingston also provided their Value memory series that performed well during testing with timings that basically matched that of the higher rated DDR2-667 modules, although voltages had to be increased above the group average. We did not notice any thermal issues with the memory due to the lack of heat spreaders or the increased voltages. Also note that this is the only 2GB Value kit that used Infineon chips instead of Elpida chips, which likely accounts for some of the slight differences.

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

Heyon 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?Gary Key - Sunday, July 23, 2006 - link
Yes...works very well by the way. ;-)
