High-Density DDR3: Five Dual-Module 8GB Kits Compared

Patriot Sector 5 DDR3-1333 CAS 9

Patriot has barely gotten its feet wet in the high-density DDR3 market, and its recently introduced PGV38G1333ELK 8GB dual-channel kit was the only package we could find to use its new 4GB DIMMs.

These DDR3-1333 CAS 9-rated modules are also the only devices in today’s lineup that do not default to DDR3-1333 CAS 8. A combination of SPD and XMP values seem to indicate that these use overclocked DDR3-1066 components.

Users with XMP-capable motherboards can easily select the rated speed, timings, and 1.65V voltage using one or two BIOS settings, while more experienced users can set everything manually. Users who can’t or won’t make manual BIOS adjustments will find that these modules default to proper DDR3-1066 CAS 7 settings and many programs show little to no performance difference between DD3-1066 and DDR3-1333.

    At an average of $200 dollars a stick I can safely say I am not an "Enthusiast" even though I love computers, hardware, consoles, games, and talking about computers.

    However my next build has almost been conceptualized (waiting for certain parts and prices), so DDR3 here I come.

    ouch 400+ for 8gb ram?

    Its about twice as much as getting 8GB off 2GB Modules. So the price increase isn't too bad considering 4GB ram sticks are the largest you can currently buy. I am still waiting for that to dip in price and for the more massive ram sticks to come along. We have been max 4GB for quite some time now.

    4 now i can live with 12gb limit on my x58 mb. But it is good to know that ppl that really need more then that can do it for affordable price

  • Only problem I have with the review is where is the same tests on a AMD platform for all us AMD users that will be or are already looking at AMD AM3/DDR3 builds.

    Yeh, ouch, but can you imagine paying $800 for it last summer? Newegg still has one of those super-expensive kits.

    dont expect more than 4gb anytime soon there really is no need in a system to run more than 4 to begin with you really dont see any speed improvements past 4 and no program is built to handle that size of memory block currently. Sure there are the occasional special systems that use more than 4gb but not for a single program. Besides that there is the TDP and FCC inforced efficiency ratings they have to come in under ram is an energy hog for an overclocker

    Tom's Hardware has recently been getting very similar overclocking and timing results between AMD and Intel systems when using the same modules and DIMM voltage. That's why the high-end system for the last two System Builder Marathons used the same RAM both times.

    What about 16GBm 1066MHz DDR3 DIMM's? Only $1,700 a piece. =D
    Granted, however, it is server ECC memory, and was never designed to be in a desktop. (Would love a 2P rig running dual 4GHz sexacore Gulftowns with HT, with 9 DIMM's per socket, running (18 DIMMs x 16GB/DIMM) 288GB of RAM.)
