First up with have G.Skill’s memory modules which are rated for PC3200 at CL2 2-2-x and PC4400 at CL2.5 3-3-x on an Intel P4 setup.
They don’t come with fancy heat spreaders, but these don’t seem necessary at all as the sticks never became very hot during testing.

Overclocking ExperienceUsing 2 memory modules the performance is severely impacted at relaxed timings. Reaching only 235Mhz, and as you can see, at that speed, performance is hardly different from running the memory at tight timings.

Timings | FSB/CPU | Q3A | 3DMark2001SE |
CL2 2-2-10 | 211Mhz / 2215Mhz | 365.4 | 14186 |
CL2.5 3-3-10 | 235Mhz / 2232Mhz | 366.4 | 14186 |
CL3 4-4-10 | <240Mhz | n/a | n/a |
By removing one module from the system the performance spiked up, 290Mhz at more relaxed timings, up to 305Mhz! (That’s DDR610 for you!) with CL3. But as you can see from the performance numbers, the 15Mhz increase does not overcome the higher latency.

CL3 4-4-10 | 305Mhz / 2287Mhz | 389.1 | 14530 |
Using 2 sticks of G.Skill in your Socket 754 system is only advised if you want to run them at tight timings. If you’re happy with using only 1 stick, the sky’s the limit (well almost).
