The Maximum PC ethos can be summed up in two words: MORE POWER! (Harder, better, faster, stronger would work, too, but that’s twice as many words – not exactly better.) MSI, it seems, heard our Tim Taylor-like grunting from afar. The company just released a modified version of its X79A-GD45 motherboard (which was only released a month ago, mind you) that includes twice the DIMM slots of the original. That means the X79A-GD45 (8D) includes a total of 8 DDR3 DIMM slots and can support up to a whopping 128GB of quad-channel RAM – because 64GB just isn’t enough.
A few months back, Loyd Case answered the popular question, “Which Video Card Should I Buy?” Needless to say, his story caused a considerable lull in video card related questions from our readers, letting a new topic take the lead: RAM. How much do you need? How fast should it be? Are latencies important? Today, we’ll be covering everything you need to know to get the right RAM for your system.
Which would you rather have, speed or capacity? If you answered either one, go ahead and deduct 200 geek points, because you should have pounded your chest and emphatically yelled, "Both!"
That's exactly what G.Skill's doing, who just launched a monster sized 24GB kit of RAM rated for 2,000MHz. G.Skill's triple-channel kit will fill all six DIMM slots in your motherboard with 4GB sticks, each one aggressively timed to 8-10-8-25, 1T.
"G.Skill previously demonstrated 24GB of DDR3 at 2,000MHz CL9 during Computex 2010 earlier this month, but has again managed to push the boundaries," G.Skill said in a statement. "This super capacity kit has already attracted a large number of extreme gamers and professional users who expect higher memory capacity can improve their PC performance. G.Skill has successfully provided 24GB (4GBx6) at 2,000MHz CL8 to another high-end boundary, making it the absolute ultimate choice for the extreme users."
That's marketing speak for a series of chest pounds and Tim Taylor-like grunts.
No word yet on price or availability, but for reference, Newegg currently sells a G.Skill 24GB DDR3-1600 kit for $1,150.
My PC has an Intel 2.4GHz Core 2 Quad Q6600, an EVGA 750i FTW motherboard, and two sticks of GSkill DDR2 with timings of 5-5-5-15 2T at 1,066MHz. Two weeks ago, I started getting random lockups and blue screens. After a lot of work, it turns out to be the RAM, which is producing errors in Memtest. However, in testing it I have found that I am getting errors in unlinked mode, at 800MHz, undervolting, overvolting, and moving the RAM around. The only time I don’t get errors is when I run just one stick of RAM. Is this actually a RAM problem or do I have a bigger issue?

What determines whether the RAM on an i7 mother-board runs as dual- or tri-channel memory? Is there a difference between RAM sticks, or is the only difference in how they are placed in the motherboard slots?
The Dell XPS desktops that have Core i7 can run as dual-channel when they have DIMMs in four slots, with 4GB or 8GB RAM. The same machine can run as tri-channel with DIMMs in three slots for a total of 3GB, or in six slots for a total of 6GB or 12GB (though I don’t know who needs 12GB of RAM.)
Could the same 2GB sticks be used in dual- or tri-channel machines depending only on how they are placed in the slots?
Tom’s Hardware reports that Intel will demonstrate Hynix’s just announced 16GB 2-rank DDR3 DIMM at this year’s IDF. This comes on the heels of Elpida Memory’s 16GB FB-DIMM in DDR2 flavor that I covered a few weeks ago.
Hynix’s new DDR3 DIMM uses MetaRAM’s DDR3 MetaSDRAM technology letting manufacturers pack four times the amount of mainstream DRAM onto these sticks and still be a drop in solution, using the standard DIMM power and thermal envelope.
Intel will also demonstrate a server with 160GB using Hynix DDR3 R-DIMMs and Meta SDRAM technology in the Advanced Technology Zone.
DDR3 MetaRAM is similar to the previous generation of DDR2 technology that enables significantly more memory in a server. An added benefit of the DDR3 MetaRAM technology is that enables larger memory capacity without negatively impacting the operating frequency of the DDR3 memory channel. It is the only technology that has been demonstrated to run 24GB of DDR3 SDRAM in a channel at 1066 million transactions per-second (MT/s). Using 3 of 16GB DIMM, users can achieve 48GB per channel running at 1066 MT/s, while other competing solutions max out at 16GB per channel at 1066MT/s.
I thought we’d never have machines using Vista’s (Ultimate and Business) 128GB RAM limit in it’s lifetime, but perhaps there is hope! If you have deep pockets you could fill the average 4 slots in an enthusiasts machine with 64GB of RAM. It most likely would be overkill. Wouldn’t it be interesting to see what the performance stats would look like?
Elpida Memory, Inc. based in Japan announced that it is going to launch a 16-gigabyte Fully Buffered DIMM (FB-DIMM), the world's largest capacity. It is based on its own unique integrated packaging technology (stacked FBGA or sFBGA) with 2-gigabit DDR2 SDRAM. Elpida has achieved development of FB-DIMM products that feature an ultra thin thickness of 7.7mm.
The chip was designed with the ultra high-end servers and workstation market in mind.
Sample shipments of the new 16-gigabyte FB-DIMM will begin later this month. Mass production is expected to get underway in the 4Q of 2008.
Now if they would just come up with 8 Gig DDR3 sticks for my next desktop build, I’d be very happy indeed!
GeIL (that's capitable 'I' capital 'L') is going Hollywood with its naming scheme for a new technology the company claims will result in higher quality memory shipping from the factory. Called Die-hard Burn-in Technology (DBT), GeIL says the new system will virtually eliminate early failure among memory modules and catch defects that otherwise would have went unnoticed.
Take a look at the new technology, and learn what you can do to both detect and prevent RAM defects after the jump.
