Memory type: DDr2 DRAM frequency 332.5 Mhz Channels: single Manufacturer; PQI for further results from CPU-Z message me as i do not have 5 posts so i cannot link hello, im not a computer expert or a tech wiz so ill try my best to explain my situation. i have recently bought a duel 4gb of RAM, so its 2gb x2 operating at 800Mhz each. i was wondering whether any1 had any suggestions to why it is not operating at the 800hz to which it should be doing, where it is only operating at around 330. i am using windows xp media edition if it helps. i have seen a drastic decrease in performance with application concerning graphics, games, media, video etc where i am suffering from unusal low frame rates (fps) i have been told that i may have to upgrade my graphics card as it is quite old, also perhaps my processor. however i believe that the problem lies with my ram settings etc. any thoughts? also isnt my ram connection supposed to be duel support? could that be the reason to why my system is only picking up 2.5gb of ram and not the full 4? do i need to enable a settting for duel channel memory as according to crucial.com my computer does support dual channel memory ty in advance.
