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

Mushkin PC3200 LVLII V2

Mushkin's previous LVL II modules have obtained legendary status in enthusiast circles; they came equipped with Winbond BH-5 chips and reached extremely high FSB speeds while retaining very tight timings. When they introduced V2 of their LVLII product line, I had great expectations. On Intel they delivered average performance, 239Mhz at CL2.5 timings, let’s see if they do better on A64.

PCB design

Mushkin is following the JEDEC reference design with an added color and their personal signature on the PCB.

Overclocking Experience

The JEDEC reference PCB fairs very well when using 2 modules, it outperforms the two Brain Power design by quite a margin. Respectable speeds at tight timings, followed by 250+Mhz when we relax the timings.

Using only one memory module does improve Overclocking, although nowhere near the heights of Brain Power design.

The Mushkin LVLII V2 modules make a nice come back, while the performance on Intel was good, they really shine when used on the A64 S754 platform!
