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
DIMMs we've tested in the past and 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 key!

While we don't have much to compare the PQI Turbo
PQI24500-1GDB against, I think it's safe to say that the memory does pretty
well for itself when overclocked.
Very fast DDR-2!
200-2001 things were very exciting in the memory world, after all the Goliath
like Intel was backing the radical RDRAM architecture while AMD was pushing DDR.
In what was one of the biggest upsets in computer history, DDR memory prevailed
as the desktop memory standard and in general has served users very well the
last few years. Now near the end of its life, DDR-2 takes over from where DDR has
left off and ironically it's early champion is Intel.
Turbo PQI25400-1GBDB is rated to run at
667 MHz by default, while maintaining 4-4-4-12 memory timings with a voltage of
1.8V. The performance of these modules was very good compared to the other test modules, but because of
the higher latencies the PQI Turbo PQI25400-1GDB wasn't commanding a lead in most benchmarks.
Realistically, the differences where small enough that
you wouldn't notice the differences in a game, or using
an application. In terms of overclocking, we were able to push PQI's Turbo
PQI25400-1GDB memory to 660 MHz, at 1.8V. This is very good for DDR-2, but
7 MHz lower than its official rated speed of 667MHz. Of course I don't believe
that this was the fault of the memory. It's much more likely that the motherboard was maxing out.
With a retail price of $422 CDN ($345 US), PQI's Turbo
PQI25400-1GDB is actually
quite affordable considering it's DDR-2 RAM. If you've jumped on
the bandwagon and are looking for some decent DDR-2 memory, it may be time
to consider a set of PQI Turbo PQI25400-1GDB.
