Introduction

Corsair TWINX2048-3500LLPRO memory kit uses two 1 GB CMX1024-3500LLPRO memory modules (219 MHz/DDR438, 2-3-2-6 timings) and is optimized to be used on ASUS A8N32-SLI motherboards series. CMX1024-3500LLPRO modules were the first to use CAS 2 latency, which is considered very aggressive in high-capacity modules (1 GB) with a 219 MHz clock. Let’s see how this kit goes on our review.

The module has the same look as the other XMS Pro series modules from Corsair. The modules have a big black aluminum heatspreader and on their top they have a series of 18 LEDs that shows the memory activity. For those that have a case with a transparent side window the effect is very interesting. On the other hand these modules are too high, what makes it difficult to use them with certain motherboards when bigger CPU coolers are used.

The reviewed modules use Infineon BE-5 chips and printed circuit board (PCB) designed by BrainPower.

Infineon BE-5 chips can run up to 260 MHz using a low operating voltage.

Before going to our benchmarks, let’s take a look on the main technical features of the reviewed modules.

TWINX2048-3500LLPRO memory kit was one of the first 2 GB kits to use very aggressive CAS latency (CAS 2) with a 219 MHz (DDR438) clock. Corsair scored a point here.

Infineon BE-5 chips used on Corsair module support a stable overclocking up to 260 MHz. We were able to configure over 260 MHz, but the system wasn’t stable for 3D applications, corrupting textures.

Patriot modules also use Infineon chips but from CE-5 revision, which have a higher overclocking capability. The good news is that newer kits from Corsair are also coming with Infineon CE-5 chips.

This kit from Corsair is perfect for the users that like low latency memories, being able to go up to 220 MHz with very low latencies (2-3-2-5) with an operating voltage of only 2.6 V.

With 18 LEDs blinking while it is working, this kit is perfect for users that have a case with transparent side window. But it is time for Corsair to make a facelift on their modules. It’s been more than two years with the same look.
