New OCZ 4GB DDR2 is AMD-only

[Viditor]

OCZ Product page

This may change down the track, but the reason it's AMD only is that all existing chipsets are limited to ten address bits, while the AMD CPUs go to 11.

Thanks for the heads up :thumbsup:

 

[cprince]

ahhhhhh, Interesting............ But seriously, not too many people would use this type of RAM because not too many people who knows about computers do CAD stuff.

nigel is in for 2...

The real question is how much real world performance will this yield.

For the lazy, here is the text specifying whe difference :

With 11 column address bit support by the AM2 memory controller, the number of addresses in each row or page can be as high as 2048 individual entries for a page size of 16kbit. Unlike modules based on standard 10-bit column address chips with an ?8k? page size, the new Titanium AM2 Special modules take advantage of the AM2 controller?s feature set and provide a single rank solution with 2GB density using ?16k? pages. This allows the controller to stay ?in page? twice as long compared to standard memory architectures, thereby achieving unparalleled performance.

For people trying to squeak out as much performance as possible, this is a nice option.

This is a marketing gimic plain and simple.

You can enable 16k pages on any set of 2x2 memory on AM2.

OCZ simply plays to people with simple minds that they are increasing their performance drastically.

I mean come on why does a company need 400 products.

DDR3 promises a new opportunity for manufacturers. Rather than having to do a whole lot of research for specific IC's and speed grades. Companies should change their enthusiast part naming scale.

For OCZ you currently have this many models available or have been EOLed during the DDR2 era (Yes these really are real):

Crossfire Ready Memory, SLI Ready Memory, Gold, Platinum, Titanium, Plutonium, Special Ops, Special Ops Urban Camo, Vista Uprade, Vista Performance, Bronze, Value, Flex, Reaper, Platinum Extreme, Platinum Enhanced, AMD Only, Platinum DFI, Titanium DFI Only, GOLD Gx, Gold XTC, System Elite and finally, Value Pro.

For DDR2 it would be simply.

PC2-6400 3-3-3-8 | D9GKX | 2.25-2.4v
PC2-6400 3-4-3-9 | Promos | 2.2-2.25v
PC2-6400 4-4-4-12 | Promos | 2.1v
PC2-6400 5-5-5-15 | Value Not IC Specific | 1.9v
PC2-8000 4-4-4-12 | D9GKX | 2.25-2.4v
PC2-8000 5-5-5-15 | D9GMH | 2.2v
PC2-8500 5-5-5-15 | D9GMH | 2.25v
PC2-8888 4-4-4-12 | D9GKX | 2.4v
PC2-9200 5-5-5-15 | D9GMH | 2.3-2.4v
PC2-9600 5-5-5-15 | D9GMH | 2.35v

At least this way the consumer knows what they are getting. OCZ is about offering numerous product lines to niche markets that offer little to no performance gain.

Remember OCZ TI 1t, which was a normal pc2-6400 set that was only relabeled to support 1T operation and price went up by $50.

And the support of 1T is really a memory controller's job, too. Not the memory itself. :disgust:

The bigger the company is, the greedier it is, i guess. (Look at ASUS' LGA775 line-ups.) Well, it's a business from their point of view, but as an enthusiast, searching before a buy is a must, IMO.

except Asus boards usually overclock and run better than the competition. However, sometimes OCZ is more money and performs lower. G.SKill, Buffalo, Crucial all offered better overclocking sets for less cash.

Yoxxy, you make it sound like it is easy, but I don't know how to do such a thing.

Care to elaborate? Will it work only on DDR2 or can it be implemented on a Socket939 with DDR?

I ask because I do work with exactly the type software they mention - Adobe Premiere Pro with large, no, HUGE video files in memory.
