Stock Memory Performance
Most Intel Socket T (Socket 775) motherboards provide a wide range of memory ratios that match available DDR2 memory. End-users can select the memory ratio that matches their DDR2 memory speed. Our memory testing begins with the same approach. We first test all of the stock ratios at the fastest stable timings we can achieve at the given ratio. With these ratios, CPU speed remains the same at 2.93GHz in our memory test bed, and memory speed is varied by selecting different ratios.
DDR2 memory is then pushed from the highest stock ratio that could be achieved in testing - in this case 889 (3:5) - to the highest FSB speed at the stock multiplier. We could not reach DDR2-1067 with this value Super Talent DDR2-800, so we settled for the intermediate ratio of 889. The system was then pushed to DDR-1000, which was the highest stable speed reached that ran our complete test suite. We were able to boot at speeds much higher than 1000, and we could actually navigate the boot screen up to DDR2-1050, but the system was not stable in Windows and could not complete our test suite, even at the highest 2.4V supported by the ASUS board. Other systems may achieve higher test results with more voltage.
At DDR2-800 the memory completed our benchmarks at 4-4-4-11 timings at just 1.95V. This is significantly faster than the rated 5-5-4-12 timings. Most boards can easily supply 1.95V, but if your board has a fixed memory voltage you may need to use slower timings for complete stability with this memory. DDR2-667 similarly required 2.10V to achieve 3-3-3-9 timings. If you can't supply 2.1V you will likely need 4-4-3-9 or slower timings at stock 1.8V.
Many buyers of value DDR2-800 memory will not have a motherboard that can supply voltages like the highest 2.30V required in our testing at DDR2-1000. If your top available voltage is less than 2.3V you will not be able to achieve DDR2-1000 performance with this memory. Top results at stock voltage will likely be in the DDR2-900 range at the rated 5-5-4-12 timings
The performance results found in our testing give most every buyer some choices when using this value Super Talent DDR2-800 in their system. If their board is voltage limited, the memory is still usable at slightly slower timings. If the board supplies a very wide voltage range, then you can likely squeeze better timings from this memory with higher voltage. With air cooling, however, the best you can expect to achieve is around DDR2-1000.

Pretty is not good by itself, but pretty IS an indication that a company has the resources to compete in the market and that they are proud enough of their product to make it want to stand out.Our past experience has been that memory that is amateurishly packaged either improves in "pretty" and stays in the market, or dwindles away in the ugly packaging in which it was introduced.

If pretty is an indication of something about a company then I'm worried about AnandTech. Those line graphs in this article are hideous, and the front page ain't too hot. At least that expanding Crossfire ad isn't running anymore.brshoemak - Wednesday, November 29, 2006 - link
this is a little OT but I sincerely hope their enthusiast memory is of a higher quality than their standard DDR memory.We bought around 30 sticks of Super Talent DDR memory and some Corsair ValueRam from a couple different distributors to build PC's with less than a year ago. So far, 16 (over half) of the Super Talent sticks have gone bad and every time I hear of a new PC problem it's almost always Super Talent memory inside.
If the enthusiast memory is better quality that's great, but due to my own personal experience I would be wary of their value-segment offerings. JMO

Users are AMD and Intel, how an Article like this be helpfull if it cover only less than half of the market ?? I hope to see three variants, Intel Core 2, Intel P4 & D and AMD's AM2 platform...Frumious1 - Wednesday, November 29, 2006 - link
In related news, reading comprehension is on the decline so things need to be pointed out with bold flashing text:Page 2:
DDR2 memory performance, in timings and required voltage, are equivalent on the AM2 and Core 2 Duo platforms. This was clearly illustrated in Conroe vs. AM2: Memory & Performance. However, the first generation of AM2 on-processor memory controller does not support any memory timings below 3, or memory speeds above DDR2-800, while both these features are supported on the Intel platform. Timings of 2 are available for RAS-to-CAS and RAS Precharge, and DDR2-1067 is a memory speed option on most Intel motherboards. The lack of extended memory timings and memory speeds makes it more difficult to test the newest high-speed DDR2 memories on an AM2 platform.
In other words, the memory timings and voltages you can get are the same on both platforms. Performance with AM2 while keeping CPU speed constant is going to improve slightly with more bandwidth just like on Core 2. Most people after high-end memory are going to overclock anyway, at which point it's just a matter of determining how high you can go with the various RAM.
Core 2 could use a 1:1 ratio and run with this RAM at up to 2000 FSB. Athlon AM2 could do "1:1" at up to DDR2-1000 as well, but there's no way the HyperTransport bus is going to run at 500 MHz base speed. So you can go with the DDR2-800 divider and get up to around 250 MHz HT speed (a 25% overclock), or you could drop to a lower divider like DDR2-667 and probably hit the limits of your motherboard. If not with the 667 setting then certainly with the DDR2-533 setting. Actual memory speeds on AM2 are a bit different then what you select anyway, depending on CPU, as the final RAM speed is derived from the CPU speed an not from the bus speed.
This is all beside the point, as the main thing to note is that this value RAM will work extremely well for all but the most demanding enthusiasts.

As far as I understand, 533MHz DDR2 will theoretically max out the bandwidth on a 1067MHz FSB, as the memory interface is 128 bits, while FSB is 64 bits. Thus, the only reason that the faster memories perform better is that the timings are relative to the clock speed and will therefore get faster with increased memory clock speed. Is this correct?Wesley Fink - Wednesday, November 29, 2006 - link
This is partly true. Memory is Double Data Rate so DDR2-533 is the 1:1 match to a quad-pumped FSB base of 266 (1067). Memory ratios run the memory faster, and it performs better, while the base FSB clock remains the same. However, there is also overclcoking. At 1:1 or any given ratio, you can overclock the bus, which overclocks the memory in lock step at the settings you have chosen.With the nVidia 680i, for example, we reached a FSB of 2100 (525 quad-pumped), which is almost a 100% FSB overclock. In that case we had to drop memory ratios so the final memory speed would work with a 2100 bus.
Memory can be clocked higher by ratios or FSB overclocks, or a combination of both. This gives many options in squeezing the most performance from your memory and system.

the point is not about working and overclockablity or not, it's about compatibility as main concern, some mobos like MSI has hard compatibility with some DDR's like OCZ, some reports they can't even hit DDR2-800 speeds so how about overclocking ??some mobos, like those from ASUS ( mainly K8N's ) need BIOS update to make it possible to work with OCZ memories in DDR2-800 in Dual channel mode, a lot of users start there rigs with two stick on only one channel then do BIOS flash update and then rearrange the stick to enable DualChannel.
some guys need to upgrade but they don't know about compatibility issues they may have with such brand new memory !!
JarredWalton - Wednesday, November 29, 2006 - link
The major concern with compatibility almost always comes from default required voltages. Since this Super Talent requires 1.8V by default, it should work on any DDR2 platform that recognizes the DDR2-800 speed. I'm sure Wes has played with the RAM on more than one motherboard, so if he hasn't made comments about incompatibilities (and he actually mentions the benefits of the 1.8V requirement) then it's about as "safe" as you can get.Cali3350 - Wednesday, November 29, 2006 - link
When might this be available, and perhaps more inportantly if it already is does anyone know where? I cannot find it anywhere.
