Apacer, a well-known independent DRAM manufacturer, has launched high-speed
DDR2 RAM modules. These modules have SPD (Serial Presence Detect) programmed to
JEDEC (Joint Electron Device Engineering Council) latency of 5-4-4-17 working at
1.8 V on 800 MHz. 5-4-4-17 denotes the CAS latency time, RAS to CAS delay, RAS
pre-charge and pre-charge delay respectively. Although the CAS latency is high
at 5, owing to the higher clock speed it performs better than a RAM module with
lower CAS latency. Most RAM modules today come with heat spreaders for maximum
cooling. However, the Apacer RAM module which comes as a pair of two 512 MB RAM
modules doesn't have any. Even then, the RAM provides for cool (literally)
operation and did not heat up even after heavy usage. We tested the RAM in dual
mode on an Intel Core 2 Duo E6300 processor running at 1.86 GHz on an Asus
Striker Extreme (NVIDIA nForce 680i SLi chipset) motherboard with an NVIDIA
6600GT 256 MB graphics card. For testing the performance, we ran PCMark 2005
benchmark which runs a series of read, write, copy and latency tests with
varying loads of 16 MB to 4 KB. The RAM modules scored 4590 PCmarks, which
though impressive, are somewhat low compared to 5900 PCmarks scored by the
Kingston RAM modules we tested in November 2006 (The configuration used for
testing was a core 2 extreme on EXC PX1 motherboard).
Bottom Line: An excellent performer when paired with a good processor
and motherboard.
