Corsair TWINX2048-3500LL PRO
Performance @ Highest Stable Clock Speed
For our next set of numbers, we focused on the maximum overclockability of Corsair's TWINX2048-3500LL Pro memory. Using an Athlon 64 4000+ CPU, we raised the HTT clock while concurrently lowering our processor's multiplier. We tried to keep the CPU as close to it's stock 2.4GHz clock speed as possible. For these tests, we locked the PCI Express clock to 100MHz, raised the CPU voltage to 1.65v, and raised the memory voltage to 2.9v. We also relaxed the memory timings to 2.5-3-3-10, which allowed us to hit much higher clock speeds.
With all of the memory kits running at the same relaxed timings and with an increased voltage, we were able to push clock speeds much higher than "stock". The Corsair TWINX2048-3500LL Pro kit maxed out at an impressive DDR498 at these settings, which happened to be 25+MHz higher than the Kingston kit, and couple of MHz higher than the lower capacity Corsair Pro kit. And while overclocked, the Corsair TWINX2048-3500LL Pro's bandwidth score jumped by about 900MB/s.
