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

OCZ EL PC3200 Platinum Rev. 2

OCZ has worked up quite an image, delivering excellent memory modules which are known for surpassing their rated speeds by quite a margin. We previously looked at the performance on Intel and A64 S939 using these sticks, but at that time that our reviewer for S939 had not discovered the limiting A64’s on-die memory controller issue.

These platinum sticks are also platinum colored, and they look “the part”, but while these heat spreaders look very hefty and good for heavy duty, I experienced very high temperatures during testing (too hot to touch), and adding active cooling increased OC limits!

PCB design

OCZ is using Brain Power’s PCB design, same one as G.Skill.

Overclocking Experience

When using 2 memory modules performance is very similar to the GSkill sticks, but OCZ is able to achieve higher speeds at tight timings.

With only 1 stick I reached highest FSB among the TCCD memories in this roundup using tight timings, topping out at 221Mhz! With relaxed timings the modules climb up to 290Mhz.

The Brain Power PCB B6U808 does not seem to cope well when using 2 modules, but they soar quite high in single module mode! OCZ’s implementation offers higher speeds when tight timings are used.
