The TCCD-pire Strikes Back? Athlon 64 S754 Memory Roundup

Memory by jmke @ 2004-11-30

We compared 5 different Samsung TCCD powered memory modules, discovering some surprising performance differences between them. To give these new TCCD chips a worthy competitor we also included results from Winbond BH-6 running with high VDIMM. How do they fair on an A64 S754 platform? Read on to find out

PDP PC3200 Patriot Xtreme XBLK

PDP introduced their TCCD modules under the “Patriot Extreme” moniker, the heat spreader makes it stand out from your other system’s components.

PCB design

PDP is also using the Brain Power PCB, however, it is a more recent revision, B6U815

Overclocking Experience

Comparing the performance with the other Brain Power PCB it is clear that this revision takes the upper hand, both at tight and relaxed timings.

Using 1 stick I was able to push the memory up to DDR610 speeds with CL2.5 3-3-10 timings, quite impressive, I had not seen Q3A fly like that, topping 400 FPS!

The Patriot Extreme modules make a very good impression, delivering good results when 2 modules are used, but really shine with only 1 stick in the system.
