OCZ 3700 GOLD: Building High-Performance Memory

Retail Performance
Both the Samsung stock DIMMs and the Lasered DIMMs were assembled from unbinned chips – chips pulled prior to sorting by performance. The final step is sorting the lasered chips and selecting the best-performing chips for the best-performing memory. Chips that do not meet the highest performance levels are used in lower-speed products.The chips are also only one component in the final performance of the product. The PCB on which the chips are mounted is very important to performance. Six-layer boards are generally lower in noise and the quality of the PCB can significantly impact the performance of the memory DIMM. The programming of the SPD is also very important in determining the final performance of the memory module.
Using the best lasered chips, we finally get to the performance of the completed Retail OCZ 3700 GOLD. In this case, we looked at Maximum Speed at SPD timings, Maximum Speed at CAS2, which is faster than rated SPD CAS of 2.5, and performance at Specifications of DDR466, 2.5-7-3-3.

| DDR Memory Speed | Memory Timings | Memory Voltage (vDIMM) |
UNBuffered Sandra 2003 Memory Test (MB/Second) |
| 466 | Specification 2.5-7-3-3 |
2.65V | 3079 INT 3146 FLT |
| 480 | 2.0-7-3-3 | 2.7V | 3175 INT 3216 FLT |
| 510 | Maximum SPD 2.5-7-3-3 |
2.8V | 3403 INT 3471 FLT |
Speed-sorting of chips yields a retail product that now reaches to a speed of DDR510 at stock SPD timings with a voltage increase to 2.8V. We also see that speed-binning is producing even faster CAS 2.0 settings, up to DDR480. Probably the most significant performance improvement from speed-binning is the memory-bandwidth, as measured by the UNBuffered Sandra 2003 Memory Test.
DDR510 is the highest stable setting that we could achieve at SPD timings, but the memory will reach even higher speeds at more relaxed timings. OCZ 3700 GOLD is one of the many included in our evaluation of high-speed DDR500/DDR466 memory modules. Look for the results in 'Searching for the Memory Holy Grail — Part 2'. Our performance comparison of the fastest memory from Corsair, Kingston, Geil, Adata, and OCZ will be published soon.

For that.. Ask Corsair how All Components is doing the job for them? LOL LOLAnonymous User - Tuesday, August 12, 2003 - link
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????????Anonymous User - Tuesday, August 12, 2003 - link

With stupid people like #54, who needs marketing?Anonymous User - Tuesday, August 12, 2003 - link
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.Anonymous User - Sunday, August 10, 2003 - link
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 anonomousIf 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.
