hi, i recently bought G.Skill 2GB DDR HZ PC4000 (2x1GB) CAS3 Dual Channel Kit (F1-4000USU2-2GBHZ) (MY-008-GS) , which is rated at 3-4-4-8 and runs at pc4000. i'm gonna use it later on my new build, but at the moment, i wanna use it on my dad's system until the new one is built. the problem is his motherboard is complete rubbish as its a basic £400 emachines pc. the motherboard only supports pc2100 ram, and as the Rams SPD settings are set beyond that, the pc won't boot with it in. is there anyway i can work around this problem? ive checked the BIOS and there are no advanced options whatsoever which can help, so input would be useful. thanks.
