Test platform: Socket F and the rest

The results of the Opteron with DDR2 that have been used in this review are the same as those that were used in an earlier article. They were obtained using a MSI K9SD Master A8R and two dualcore Socket F Opterons clocked at 2.4GHz. The board uses a Serverworks chipset and has a PCI Express x8 slot, a 133MHz PCI-X slot and a standard PCI slot. A fourth slot can be selected by the customer: depending one the riser card used, the fourth slot is either PCI Express x8 or an HTX connection (HyperTransport).

On board we find two times gigabit ethernet and eight times SATA (four of the Serverworks chipsets with support for RAID 0 and 1, and four Adaptec AIC-8130 sets supporting RAID 0, 1, and 10). An integrated ATi Radeon Mobility takes care of the imagery. However, it is especially the large number of memory slots, totalling sixteen, that makes this board stand out. Unfortunately, stability problems with our preproduction hardware made it impossible to put more than four modules to work. We ended up testing with only 4GB of RAM, less than the other systems had at their disposal. The few results that we managed to obtain with the 8GB Socket F system allow for the conclusion that performance loss due to the lower memory capacity was about two percent, which needs to be taken into consideration when reading the diagrams.

Beside the Socket F board we shall encounter the results of two other familiar faces in this article: the Sun X4200 and T2000 from our UltraSparc T1 vs. Opteron review. For completeness, we list all specifications below.
