For our next set of numbers, we focused on the overclockability of Corsair's TWINX1024-3200XLPRO modules on our Intel test bed. Using an unlocked Pentium 4 3.2GHz CPU, we raised the Front Side Bus speed while concurrently lowering our processor's multiplier. We tried to keep the CPU as close to it's stock 3.2GHz clock speed as possible. For these tests, we locked the AGP/PCI speeds at 66MHz/33MHz, raised the CPU voltage to 1.65v, and raised the memory voltage to 2.9v.

Overclocked Performance with SiSoft SANDRA 2004

Raw Bandwidth

These scores illustrate the highest stable clock speeds we were able to hit with the Corsair modules configured with 2-2-2-5 timings, and then again with 2.5-3-3-8 timings. The "stock" scores are the DDR400 numbers with timings set to 2-2-2-5. With the fastest timings, we were able to take these Corsair sticks all the way up to 220MHz (DDR440). At DDR440, bandwidth scores in SANDRA jumped by about 9% in both the ALU and FPU tests. With less aggressive timings, the Corsair sticks actually hit 247MHz (DDR494), which resulted in roughly a 19% increase in bandwidth. With even less aggressive timings, DDR500+ speeds are a definite possibility with these modules.

Marco's interest in computing and technology dates all the way back to his early childhood. Even before being exposed to the Commodore P.E.T. and later the Commodore 64 in the early ‘80s, he was interested in electricity and electronics, and he still has the modded AFX cars and shop-worn soldering irons to prove it. Once he got his hands on his own Commodore 64, however, computing became Marco's passion. Throughout his academic and professional lives, Marco has worked with virtually every major platform from the TRS-80 and Amiga, to today's high end, multi-core servers. Over the years, he has worked in many fields related to technology and computing, including system design, assembly and sales, professional quality assurance testing, and technical writing. In addition to being the Managing Editor here at HotHardware for close to 15 years, Marco is also a freelance writer whose work has been published in a number of PC and technology related print publications and he is a regular fixture on HotHardware’s own Two and a Half Geeks webcast. - Contact: marco(at)hothardware(dot)com
