Introduction:
GeIL is a modest manufacturer that
was founded in 1997. They have made other memory manufacturers stand up
and take notice, and have gained a lot of fame in a very short time.
Those that may want to know, GeIL stands for Golden Emperor
International Ltd. Today we have the chance to review some GeIL CAS 1.5
DDR memory. Memory that runs at this latency is rare and is not easy to
find. This DDR can run at 250MHz at CAS 2 with nice tight 2-2-5
timings.
As you probably already know, memory today has a huge impact on
applications and games. Large amounts of good memory can drastically
increase performance of applications/games like Battlefield 2. The ONE
series is the latest DDR offer by GeIL and it’s available in two
versions, Samsung TCCD and Winbond BH. This review concentrates on the
BH version. GeIL offers a lifetime warranty for both versions.
Samsung TCCD
The Samsung TCCD version can reach 600MHz with timings set to CAS
2.5-4-4-7 and 400MHz with timings set to CAS 1.5-2-2-5. It’s
available in both 512MB and 1GB Dual channel kits. It requires voltage
between 2.55v-2.85v. It has their Platinum Copper Heatspreader and a
Life time warranty.
Winbond BH (Current Review)
On the other hand, The Winbond BH version can reach 500MHz with timings
set to CAS 2-2-2-5 and 400MHz with timings set to CAS 1.5-2-2-5. These
memory modules also include the Platinum Copper Heatspreader and come
with a lifetime warranty. The BH memory chips require more voltage then
the TCCD ones do. The Winbond BH chips require 2.75v-2.95v to reach
speeds of 400MHz and 3.4v-3.8v to reach 500MHz. Currently the
only motherboard manufacturer that allows DDR voltage up to 4v is DFI.
Because of these high voltage requirements you will not be able to
reach 500MHz with the BH chips unless you have one of the latest DFI
motherboards. We took a different approach and modified our own
motherboard to increase the voltage via a hardware mod. The reason for
the voltage limitation is the motherboard design using the 3.3v rail
for power. Since DFI is targeting gamers, they made it possible to use
extreme voltages using the 5v rail. Personally, I think the other
manufactures should follow.
