Corsair Memory has announced a bunch of very interesting products this month that definitely worth mentioning in the news-wire, as some of the peculiarities of their memory modules are unique in some way. According to what we learnt, in addition to the existing eXtreme Memory Speed product line, Corsair will also offer the so-called LL modules with ultra Low Latency settings and also pairs of modules that are tested together and intended to work in dual-channel configurations.

Let us provide a little bit more information about the LL product-line. As many of you probably know, currently Corsair sells DDR333, DDR 370, DDR400 and DDR433 XMS modules with CAS-2 setting. In order to achieve higher compatibility with all mainboards available on the market (even those which are cheap and do not have any advanced functions), Corsair ships all its CAS-2 modules with very “moderately” programmed SPD timings. Those, who want to achieve higher performance, should disable “SPD Autodetect” setting in BIOS and adjust the latency settings manually. It should be noted that even the fastest DDR433 modules by Corsair are programmed with 2-3-3-7-1T settings (see this news-story) that cannot be called as “low-latency”. There are also those customers, who do not want to adjust any settings in BIOS and prefer to get a product that will run at the fastest settings possible out-of-the-box. For those clients Corsair offers their LL modules with 2-2-2-5-1T SPD settings. In order to ensure the stability, the company simply downgrades the frequency of their memory chips, but enables aggressive timings here. For example DDR333 LL module is nothing more than a DDR400 XMS module with low-latency timings and decreased clock-speed of the chips. The DDR400 LL module equipped with 5ns chips is basically a DDR433 XMS downgraded to 400MHz.

Keep in mind that the DDR333 LL modules are DDR400 XMS modules running at 333MHz and programmed at 2-2-2-5-1T while DDR400 modules are the re-marked DDR433 XMS modules and programmed with 2-2-2-6-1T settings. Honestly speaking, those of you, who want to play with the DRAM settings can definitely transform XMS module into LL module and otherwise, therefore, the whole Corsair’s initiative is introduced just in order to make it easier for some of you to choose your memory modules.

The TWINX are pairs of LL memory modules that were physically tested together on the nForce2 powered mainboards and packed together as a bundle, to offer highest speed in dual-channel configurations. The latter are going to be really popular this year, since there will be Intel’s E7205, E7505, i865-series, i875, VIA’s P4X600 and SiS’ 655-based mainboards, all offering dual-channel DDR SDRAM memory support. Thus, expect a lot of bundles like TWINX to enter the market soon.
