OCZ PC3200 Premier
In the past two years, OCZ has moved from relative obscurity to becoming one of the most widely recognized names in enthusiast products. Today, OCZ markets power supplies, heat sinks, memory voltage boosters, and thermal compounds, but OCZ is still best known for their enthusiast memory. Recently, OCZ has also been quite innovative in new product introductions, including products like our current RAM Speed champ, OCZ VX, which requires a very non-standard 3.5 to 3.6V to really shine.What many forget is that like Corsair, Kingston, Mushkin, and other full-line memory companies, OCZ has a very large line of value products. The Premier Series is a Value line, and the PC3200 Premier is a typical Value product, with a web selling price as low as $121 at mWave.
Specifications
OCZ rates their PC3200 Premier at the more aggressive CAS 2.5 timings at DDR400 and stock voltage.| OCZ PC3200 Premier (DDR400) Memory Specifications | |

Test Results
The OCZ PC3200 Premier is the first Value RAM we have tested that reaches DDR480, our next test point on the 2.4GHz ratios. Our samples actually booted as high as DDR500, but memtest86, Super Pi and games were not stable beyond DDR480, regardless of voltage.| OCZ PC3200 Premier (DDR400) - 2 x 512Mb Double-Bank | |||||||

The Premier actually did a bit better than specified at DDR400 with stable 2.5-3-2-6 timings. It is also worth noting that Premier was stable with CAS 2.5 timings all the way to the memory speed limit of DDR480. This is particularly outstanding performance for a memory that actually sells for $121.
Aida 32 is now available as Everest Home Edition, a free download from www.lavalys.com. Everest has been very useful in measuring read/write performance and memory latency.

With OCZ Premier covering a broader range of memory speeds from 400 to 480, there is more potential to see the true impact of memory speed on performance. With memory timings at a consistent 2.5-3-3 and CPU speed at a constant 2.4GHz, any performance deltas are the result of true performance differences. As we move from 400 to 480 - a 20% speed increase - memory read improves by 15%, write improves by almost 40%, and latency drops by about 17%.
However, these improvements in synthetic memory benchmarks are not reflected by similar improvements in benchmarks with real games. Improving memory speed by 20% - from 400 to 480 - at the same CPU speed improves gaming performance by just 2% to 3%. Clearly, we are getting a better performance increase than this in real-world performance with faster CPU speed. You can see this in the 10% CPU speed increase from 10x240 to 11x240 at the same memory timings. This 10% CPU Speed increase improves gaming FPS by about 8%.

when did value ram cost $200 for a gig...dvinnen - Monday, April 11, 2005 - link
Anyone else finding these Value VX moduals? The link above timeings are 3-4-4-8, not 2.5-3-3-7.JarredWalton - Monday, April 11, 2005 - link
Please remember that it is rarely feasible for reviewers/sites to go out and buy all the hardware for a roundup. Wes submitted requests to several manufacturers, and this is what *they* felt like sending for testing. Of particular note is the comments from Corsair - they are not alone in rotating chip types on their value RAM. Maybe that is why several companies (i.e. Mushkin) didn't simply send their cheapest RAM.Looking around at various resellers and the pricing Engine, there are quite a few other RAM manufacturers/models out there worth considering. Corsair, Crucial, PDP, PQI, G.Skill, and several others have some really good RAM at $150 or less. You can even find PC4000 rated RAM for around $160 now.
Trust me, it's not practical to try to do a roundup of ALL value RAM. There are just so many models out there, all with different performance characteristics. If you don't want to overclock (at all), most of the $90 to $120 RAM will work well.
We should also have a "Your Mileage May Vary" clause in the article, as what Wes achieved is by no means a scientific sampling of each product. That would require at least 10 samples of each, and when you take the amount of time required to test OC'ing on *one* DIMM setup, it would take months to complete a scientific sampling of RAM.

quite right tony, was well done and hope to see further editions of the article. paying less and getting more is always good :)bigtoe36 - Monday, April 11, 2005 - link
Typos's..."seem" is seen, "we" is were...se we all make mistakes.bigtoe36 - Monday, April 11, 2005 - link
VX runs well with 2-3-2 timings with lower voltage. I have seem 233fsb 2-3-2 at 2.8V or so which is a little faster than 2.5-3-3 at the same fsb ;-).Regarding the modules that we not tested, you have to remember there are hundreds of different types of ram, not all can be reviewed in one go, I suspect this review alone took quite some time to complete as the AT LABs are a real busy place...i know Wesley is VERY busy not only reviewing but also pushing manufacturers to get boards overclocking better and pushing the enthusiast movent forward.
If only you guys had any idea of what Wes has done for the enthusiast over the past 2 years, i do and please take it from me the boards you are seeing at the moment are the fruits of that work.
Well done Wesley, nice review as always, even with the odd typo in amoungst the 8K words you wrote ;-)

Well, anyway, what about the decent Mushkin CAS 2.5 for $84? It seems like a much better deal than the one they tested.http://www.newegg.com/app/ViewProductDesc.asp?desc...
reactor - Monday, April 11, 2005 - link
wouldve like to have seen mushkin blue line and twinmos tmii400, both are supposed to be good comptetitors to the Value VX/BH from OCZ.Cygni - Monday, April 11, 2005 - link
They reviewed Value ram from the MAJOR mfts, they didnt review no name or OEM pieces, just brand name retail stuff.bobsmith1492 - Monday, April 11, 2005 - link
Who picked these.... :(What about the V-data 3200 CAS 2.5 ram for $70/gig at Newegg or the Mushkin CAS 2.5 for ~80? The ones in the review seem more expensive for slower ratings than most of the stuff at Newegg.
That said, the $115 VX value sounds pretty sweet.
