great to see how individual memory stacks up against the competition under stock
configurations, but we're also going to show how it compares when overclocked.
With performance in mind, we're going to compare the maximum overclocked results
of the various DDR2/3 memory modules PCSTATS has tested in the past which are
listed below. Remember, just because memory is clocked fast doesn't mean it's
the best thing for a computer. Timings are also important, and getting the right
ratio of both is the real key to performance based overclocking!

DDR2 and DDR3 memory speed/timings are not directly comparable it's amazing to
see how high the new DDR3 memory modules overclock. The Corsair DOMINATOR
Twin3X2048-1800C7D is damn fast hitting a sweet 1920 MHz, of course with very
lax memory timings.
Welcome to the world of
Ready or not here comes DDR3 memory! When dual core
processors were introduced, both Intel and AMD shifted over to DDR2 quickly so
their processors could get maximum bandwidth. When quad core chips are thrown
into the mix, DDR2 just can't keep up.
DDR3 picks up from where DDR2 left off, and as you can
see the initial sets of memory hitting the market can already clock pretty darn
high! DDR3 is rated to run 1600 MHz+ according to JEDEC, let's hope that the
governing standard increases that speed limit further!
Enthusiasts and Corsair go together like milk and
cookies, and as expected Corsair is one of the first manufacturers to actually
get its DDR3 memory modules to the market. Corsair's 2GB DOMINATOR
Twin3X2048-1800C7D DDR3 memory kit is wicked fast, but that speed comes with a
very high price tag: $678 CDN ($645 US, £320 GBP). Compared to
what we're used to seeing from ultra high end enthusiast grade DDR2, it's
pricey. Compared to a similar class of high end DDR3 memory on the market, it's
actually quite comparable.
The cost of DDR3 memory in this class is certainly high,
but there are no other alternatives which match the Corsair DOMINATOR
Twin3X2048-1800C7D's specs right now.
Corsair's specialty has long been overclocking, and
with DDR3 it's a whole new ball of wax. New mult-core CPUs, new motherboards and
chipsets, and a new class of memory. The DOMINATOR Twin3X2048-1800C7D
overclocked very well. The DDR3-1800 modules are rated to run at 1800 MHz by
default, and PCSTATS was able to best that by another 40 MHz with CAS Latency
timings of 7-7-7-20 on the Asus Blitz Extreme P35 Express motherboard! Loosening
the DOMINATOR's timings to 8-8-8-24 allowed it to overclock to a sky high speed
of 1920 MHz!
Corsair has put together an impressive set of DDR3
memory this early in the game. Its DOMINATOR Twin3X2048-1800C7D DDR3 memory is
darn fast, there's no denying that. The Twin3X2048-1800C7D DDR3 memory will only
appeal to enthusiasts who desire the absolute fastest PC on the planet, and have
a thick wallet to back up those aspirations... If you're an average computer
joe, going DDR3 won't do much for you, as it stands right now. If you're a speed
freak, with your sights set on a 1333FSB quad core and looking to break
overclocking records, Corsair's 2GB kit of DOMINATOR Twin3X2048-1800C7D is one
of the tools that will help you get there.
