If I read this page: http://www1.ap.dell.com/content/products/category.aspx/enterprise_nz? c=nz&l=en&s=bsd On the left there is "PowerEdgeTM SC430 Dual-Core Tower Server Bullet Intel® Celeron® D Processor 326 (2.53GHz, 256KB L2 cache, 533MHz FSB)" etc. In the fine print of this page http://www1.ap.dell.com/content/products/featuresdetails.aspx/pedge_sc43 0_nz?c=nz&l=en&s=bsd&~lt=popup&~tab=specstab I find it is only dual core if the Intel Pentium D CPU is purchased. Is there actually no Celeron dual core option or none of the other CPUs offered with this model i.e. it is only dual core if you purchase the right CPU option.
