The Memory Market
The memory manufacturers we’ve spoken to are ecstatic about AMD’s move to DDR2, as they can begin moving away from DDR.
While DDR shipments still outnumber DDR2 shipments, the shift is definitely taking place. Right now there is a price parity between DDR-400 devices and DDR2-667 devices; combined with AMD’s move to Socket-AM2 and the conditions are ripe for a serious transition over to DDR2 in the market. If Conroe ends up being as popular as everyone is expecting it to, the number of DDR2 platforms will continue to increase as will the demand for DDR2 memory.
The breakdown of DDR2 shipments is particularly interesting, with the majority of modules still being DDR2-533. Now that the price difference between DDR2-533 and DDR2-667 has gone down tremendously, we will see the balance shift more towards the latter.
Unfortunately DDR2-800 is still extremely expensive compared to DDR2-667, because of extremely poor yields. One source told us that DDR2-800 was yielding far below 50%, resulting in anywhere from a 30% to 100% premium over DDR2-667. Everyone expects the yields on DDR2-800 to increase tremendously later this year, which will help drive DDR2-800 prices down as well as increase the number of low latency or higher bandwidth DDR2-800 parts.
Samsung has been talking to its partners about the move to DDR3; by the end of this year Samsung is supposed to be sampling DDR3 modules, but the memory makers we spoke to believe that the schedule is too aggressive.
Currently on Samsung’s roadmaps we’ve got DDR3-800, 1066 and 1333, but things could very well change by the time DDR3 actually makes its introduction on the desktop. The memory makers we spoke to expect to see the beginning of a transition to DDR3 by the end of 2007 at the earliest, which seems plausible.

No, transparent side windows already did that ;-)

So what happened to ASRock boards (supposedly page 18)?bongobear - Tuesday, June 6, 2006 - link
I'd like to see what ASRock have lined up as well, however the mini-ITX Albatron boards that were shown in their place were a nice surprise. If they can tweak those a little and get them out at a nice price, very tempting....JarredWalton - Tuesday, June 6, 2006 - link
Anand has a ton of pictures and information from his trip, so he'll probably provide a second update later. However, I've updated the page links to correctly reflect the Albatron content on page 17.Stele - Tuesday, June 6, 2006 - link
There are actually two major types, one (the more common) being filled with solid compound as noted, and are simply called solid electrolytic, or solid aluminium electrolytic capacitors. The other type uses non-solid electrolyte. Both types are better than the usual electrolytic capacitors of course in terms of resistance to high temperatures - generally around 1,500-3,000 hours at 105°C-125°C. Another useful characteristic is that they perform well in high-frequency, high-capacitance applications, which is one reason they've often been used on graphics cards, for example.
They are however not immune from leaking and other capacitor related failures... it's just that they can survive prolonged exposure to higher temperatures for longer periods of time than the regular electrolytic capacitors before they too fail.
This, unfortunately, is non sequitur i.e. it does not follow. Component choice is but one of so many factors in determining the stability, performance and reliability of a product. A cheapo backyard manufacturer could boast 16-phase power, all-Nichicon/Rubycon solid electrolytic caps, Philips MOSFETs and AMP connectors all around but would still fail if the circuits were designed by a half-baked engineer fresh out of college and poorly manufactured. Of course, it could be used by the said cheapo manufacturer as a gimmick to fleece the gullible consumers (of which unfortunately there are very many) who rocket to seventh heaven on seeing such big names. Or a not-so-cheapo manufacturer could make their product more attractive by using such flash while cutting corners on areas where consumers probably won't notice in perhaps the first 6 months of use.
Speaking of gimmick, as mentioned above these capacitors are more useful in high-frequency, high-temperature applications. Naturally not every single circuit nor square inch of a motherboard would call for them and hence the extra cost of 100% solid electrolytic capacitors is unnecessary - they cost in the order of 3-5 times that of regular electrolytic caps, and when added up the savings could certainly be better used elsewhere on the board. For now, at least, other than the circuitries that really could benefit from the solid electrolytic capacitors, I would agree with the other manufacturers that indiscriminate plastering of the board with them is rather more marketing gimmick than engineering.

Anand/Jarred...I have a few questions if you get time.1. How is the RAS functionality for Woodcrest with the Asus server board?
2. Do the FBDIMMs require active cooling, and if so how much?
3. When Asus released the A8N32-SLI, they hinted at releasing more boards with the 8 phase power...have/will they?
4. Any chance on finding out what the functionality is for the 1207 pins on Socket F?
Cheers! And thanks for the article...!

after all this time and the floppy still lives on ...... ;)Calin - Tuesday, June 6, 2006 - link
Floppy is still the only way to load certain drivers for hard drive controllers in Windows (during installation). And as long as this will be the case, the floppy will live onDigitalFreak - Tuesday, June 6, 2006 - link
Fortunately, this problem goes away with Vista. I'm hoping that in a couple of motherboard revs, those damn things will go away.JarredWalton - Tuesday, June 6, 2006 - link
I linked in higher res images for some of the more interesting photos Anand took. If you would like to see any others in more detail, let me know (via email) and I will see about adding those. Note that some images are left in "lo-def" because it reduces blurriness. :)Take care,
