[BenchmarkReviews] DDR3 Memory: Technology Explained

post #1 of 11
Thread Starter 
Quote:
These are uncertain financial times we live in today, and the rise and fall of our economy has had direct affect on consumer spending. It has already been one full year now that DDR3 has been patiently waiting for the enthusiast community to give it proper consideration, yet it's success is still undermined by misconceptions and high price. Benchmark Reviews has been testing DDR3 more actively than anyone, which is why over fifteen different kits fill our System Memory section of reviews. Sadly, it might take an article like this to open the eyes of my fellow hardware enthusiast and overclocker, because it seems like DDR3 is the technology nobody wants bad enough to learn about. Pity, because overclocking is what it's all about.

First and foremost, DDR3 is not just a faster version of DDR2. In fact, the worst piece of misinformation I see spread in enthusiast forums is how DDR3 simply picks up speed where DDR2 left off... which is as accurate as saying an airplane picks up where a kite left off. DDR3 does improve upon the previous generation in certain shared areas, and the refined fabrication process has allowed for a more efficient integrated circuit (IC) module. Although DDR3 doesn't share the same pin connections or key placements, it does still share the DIMM profile and overall appearance. From a technical perspective however, this is where the similarities end.

I'm still not paying $500 for 4Gb of memory when mine is only $105 after MIR. That is why hardly anyone is buying DDR3.....not due to misinformation on forums

I wasn't aware DDR3 chips were built on 90nm processes. With TSMC offering 40nm, DDR3 would be blazing fast if the memory manufacturers used that node....

not quite. still expensive yes but if you are finding them for 500 bucks your looking at the wrongs spots or talking the uber high end stuff.

OCZ has some pretty good 2GB kits for around $150 these days... I might switch to DDR3 at the end of the year

I can see DDR3 being worth it soon but really, there is no point switching too it now...I just waiting for new Intel Platforms too come out and have DDR3 the standard and better timings....just little bit better...I think company's are wasting there time making DDR3 Sets but thats just my
post #7 of 11
I don't see what all the hubub about ddr3 is with timings unless you are talking the value sets. there are many ddr3 modules that are able to get just as good of timings as ddr2 and some of them are even better then ddr2 it seems at least when comparing them stock.

The only misinformation on the forums comes directly from BMR's own shameless self-promotion. He/She had a lot more posts like the one below, but it seems most were removed. Really in poor taste to link back to your own site... (Das Capitolin = BenchmarkReviews)

Actually the tech has been discussed Ad nauseam(and long before you guys broke the story).

Xbit -> DDR3 SDRAM: Revolution or Evolution?
Anand -> DDR3 vs DDR2
Tom's -> Ultimate Ram Speed tests

Quote:
DDR3 system memory reduces the base power consumption level by nearly 17% compared the 1.8 V specified base power requirement for DDR2 modules. Taking this one step further, consider that at the high end of DDR2 there are 1066 MHz memory modules demanding 2.2 V to properly function. Then compare this to the faster 1600 MHz DDR3 RAM modules operating at 1.5 V nominal and you'll begin to see where money can be saved on energy costs - conserving nearly 32%
LMAO, yes you'll save so so much on energy costs... because 32% less from an already infinitesimal power draw equates to maybe 1 watt less per DIMM. PSU efficiency > GFX card > CPU > mobo/chipset > CD/DVD/Blu ray drive > Hard drive >/= fans > RAM (finally). Long story short you don't upgrade to DDR3 to save money at least not while DDR2 is still significantly cheaper.

G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1000 (PC2 8000) $90 shipped (2.0-2.1 vDIMM)

OCZ Platinum 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) $287 shipped after $40MIR (1.9 vDIMM)

All in all, DDR3 isn't perfect. It's unquestionably better than its predecessor, but I think my points have illustrated that the good also comes with the bad. For the past year our concentration here at Benchmark Reviews has constantly centered around DDR3, as if it's a new toy to play with. But it's not; DDR3 is here to stay, and whether you want it to or not the market will soon be treating DDR2 the same way it presently treats DDR. You can cling on to your old technology, but at this point that would also be like reverting to AGP discreet graphics... which also cost a lot less than PCI Express. But that's for another article.
Nobody is "clinging" to DDR2... When DDR3's pricing reaches a reasonable level (or perhaps when DDR2 prices rebound) you will see mass adoption especially by the enthusiast community. But for now DDR3's marginal performance boost over DDR2 does not justify it's price, sorry.

Oh, and no AGP discreet GFX is not cheaper than PCIe...
