Post-Laser Performance

The lasering process includes the removal of a small amount of surface from the Samsung chips, and OCZ remarking the chips.




The OCZ remark indicates a performance rating of 4.3ns, which is quite an improvement from the original Samsung rating.




We have already seen the Samsung chips perform well beyond their rated performance and timings, so what effect does the Laser process have on performance and timings? Is the claimed 4.3ns rating after laser treatment justified?

To offer a better comparison to the finished product, we looked at the HIGHEST overclock at SPD timings, the required voltage at OCZ 3700 GOLD rating of 2.5-7-3-3 and DDR466, and the lowest voltage required for SPD 3-8-4-4 rating at DDR466.

As OCZ claims, the laser process seems to have a significant effect on performance in two areas. First, it allows the memory chips to achieve a higher overclock. In our tests, the maximum overclock went from 476 to DDR500 – just with the laser process. Second, and more important, lasering appears to allow the use of lower voltages at the same memory speeds. In our test at DDR466 and 2.5-7-3-3, the laser process reduced the required memory voltage (vDIMM) for stable performance from 2.8V to 2.65V. This is a significant improvement in specifications.

    OK- Great hope they are turning their business around. Ask them to why does some of the modules have the Delta Omega logo?? Is PDP still building for them????????

    With stupid people like #54, who needs marketing?

    Everyone is better than the OCZ every knowledgeable person has come to know and despise.

    The question is, if, as is claimed, they have repented, why even keep the old, blackened name? There's no good reason.

    Going back to when corsair were first marketing XMS2700 in the UK they sent review sites and stores based in the UK modules based on Samsung CTL CB3 IC's.As you may know these IC's were truely awesome and all the reviews showed the ram hitting ddr400+ with tight timings.One large UK based store even pealed off the heatspreaders on their forum and showed the modules in all their glory...we were all bought and imediately ordered.

    Well the modules started arriving and nothing worked as well as the review samples Corsair had sent out...So we all removed the heatspreaders off out modules only to find Micron PC2100 under them.All posts made on one particular forum about this were edited out at corsairs request, the review was heaviliy edited and RMA's were refused as we had removed the heatspreaders.

    Don't tell me Corsair are any better than OCZ because they are not...I don't see any Corsair basing here though.

    OCZ are working hard on what matters to customers today...Good ram and an excellent after sales service.If you have a problem im sure an email will get them helping you...

    Yeah, god forbid a company attempt to create a good product. You people going to tell me that Corsair hasn't done shady things to sell products? You've got to be kidding. I wouldn't be surprised if at least one of the people slamming OCZ here work for Corsair or some other company. OCZ are putting out some killer memory right now, who cares what they've done in the past? Or what they'll do in the future? And since when has our quest for the best performance ever been about the company? Gimme the good stuff, I could care less who's making it. You fanboys need to get a grip.

    I work at ocz , for those of you calling OCZ a fraud , or bashing OCZ can you do us all the great favor of posting under your real name , instead of as anonomous

    If you had some genuine problem with ocz email me
    oczguy@ocztechnology.com , we certainly did not always have the great service we do today and if you had a problem I would personaly be glad to help you . Also it seems many people confuse us with other companies.

    If you have not had a problem , or are not willing to resolve it ,please stop spewing garbage anonomously. Otherwise I cant help but think that your simply an employee of our competition spreading rumour for your own gain.

    I challenge anyone with a real past problem to email me , so that I can at least have the opportunity to solve it. If you have not had a problem please refrain from the trash talk.

    I am not saying here that people did not in the past have service problems with ocz , to be clear , I am however saying that the level of trash talk in the comments sections is out of control. Anyone who has in the past had a problem can contact us to have the issue resolved.

    Enough said



    thanks for listening to my rant -OCZGUY

    The advantage of being a very large site like AnandTech is that ALL of the memory makers advertise here. I will not justify the last comment with a defense, but if you look around you will see how ridiculous these comments really are.

    I came from a site that had no advertising while I was there, and from the first time we talked Anand has encouraged my independence. Why is it that when we report information that is different from what you might believe, it is proof we have sold out? The real sell-out here is some of the narrow-minded self-serving and totally false comments that have been posted as commentary.

    It is truly amazing what some people will say when they can hide behind 'Anonymous'.

    Hehehe, OCZ is nothing more then a marketing firm. The so called plant is a "memory plant" that OCZ went into business with. The so called "memory plant" is where they bought their memory 2 years ago. They needed to move out of Indiana because of the amount of fraud that was being reported.

    If half of you did your research about this company you would realize. Want to know the true info? Ask Martin Krohn. He witnessed the true nature of the company.

    You see OCZ on Anandtech it's not because of their products it's because they paid Anandtech for advertising. Do you really think Anandtech would "turn down" paying clients? This is a business now folks. I can guarantee you that no bad reviews of any of the paying advertising clients are on this site. Anandtech is a total sell out. Just look at their GeForce FX 5900 review! That has never been fixed yet either! This site is horrible now. It ranks up their with Toms and now [H] big business sites suck.
