OCZ 3700 GOLD: Building High-Performance Memory

Testing the Process
The Lasering explanation sounds good, but we at AnandTech are proud of being skeptics. Armed with the impressive base numbers above from a totally different source, we asked OCZ Technology for more info on their process. Furthermore, we asked OCZ for DIMMs made with unbinned, unlasered chips, as well as unbinned, lasered chips. The requested samples were received the next day.
As you can see in the unlasered samples, the chips are indeed Samsung TCB3. However, the Samsung labeling on the chips used by OCZ indicate a later revision number (E) than our earlier Samsung on the Crucial DIMMs (D).
A quick check at Samsung shows the later chips rated at the same specs to DDR400. We asked Ryan Peterson of OCZ about the significance, if any, of the later revision. He indicated that the later E rev chips do perform better at high speeds than D rev chips.

This coments sections is full of trash, what does any of this have to do with the articleMS - Saturday, August 9, 2003 - link
Kristopher,Then that is Corsair, even though they always fervently denied any such practice. Whenever I talked to Robert Pearce, he claimed that it is basically a random choice of module that goes out. I know for a fact that this is how things have been and still are handled at Mushkin, they don't even have the manpower and setup to cherry pick anything.

All I can understand (& know already) is thatyou guys just have to know where to buy the same
stuff they sell you for at least half the price.
I bought modules using the same chips rated as ddr33 - & at oem ddr33 price.
Laser This :).
Ill Just use 2.8 & skip your lasering & Rebadging.

Geez, such an uproar over this OCZ stuff. The memory works!KristopherKubicki - Saturday, August 9, 2003 - link
MS:I can send you some more evidence if you want? That is pretty much Nicole's job at Corsair to make sure reviewers get the best samples for reviews ;)

Kristopher, I can assure you that neither Corsair nor Mushkin cherry pick any of their review samples.Wesley, I don't mean to say that OCZ quality is bad at all. All I say is that the "EL" process serves a purpose that is different from what OCZ claims. [grin]

After reading the article I was wondering if the el ddr process and lasering was so effective then why don't more people do this? Even why Samsung does explore this route. Then I realized what I missed. they are removing 7mill from the surface of the chip. In the chip world size does matter and when you move from nanometer to millimeter thats HUGE. This approach is very risky. I know to well that some mothboards are finiky with memory and I wonder how well today's boards will work with this aggressive approach.Wesley Fink - Saturday, August 9, 2003 - link
Michael - Your review at Lost Circuits and the less stellar performance of the TCB3 modules I had gave me the idea for the article I did here. There is one VERY important piece of info that you do not share here. You bought retail GOLD, and as you stated in your review conclusion, it DID indeed meet specifications and beyond. We can debate the effectiveness of methods all day, but, in the end, performance and reliability is why we buy memory - whatever the brand.Anyone who doubts that MS found the retail memory met spec can check his review of the OCZ3700 GOLD at Lost Circuits.

#29 Someone mentioned it earlier. The memory companies are all "nice" but they all have their misgivings. Do you think Mushkin hands you a stick they found laying on the ground in the fab? Any manufacturer gives you creame of the crop products for a review. Thats just common practice.Kristopher

#28-that is exactly my problem with this article. Are just supposed to believe that the chips all came out of one pile, and half were lasered and half weren't? I'm sorry, but OCZ hasn't earned any sort of right to be taken at their word. Mushkin or Corsair MAYBE, but certainly not a company with a well established history of buying reviews.
