memtest is just another memory bandwidth test.. they dont relate to real life system performance..
for example if i do something to my system that doubles my score in 3d mark 2005 or 2006.. in real life i see a similar gaming frame rate increase.. or at least a pretty noticable one..
if i do something that doubles my memory bandwidth in any memory speed/bandwidth benchmark in real life i see no frame rate increase or any other difference in any game thats user noticable..
if for example i take the cpu speed benchmark in sandra that tells me a dual core cpu will exactly double my cpu performance to be true.. i go out and buy one and run a game.. i will see bugger all difference in frame rates..
tell u one thing that will hit u in the eye as regards game loading times.. i do have all these heavy games by the way.. that is having 2 gigs of system memory as opposed to just the one..
whilst argueing that memory speeds and timing make little difference to real life performance.. i would argue the opposite about the amount of memory.. having two gigs hits u in the eye as regards loading times.. so does the size of the textures u use..
level loading comes of your hardrive anyways.. cant see how memory speeds are gonna speed up that slow beast much.. with more memory less has to come of the hardive.. that speeds things up significantly..
its all these memory and cpu benchmarks we run that are going around proclaiming the wonders of the emperors new clothes.. they have a lot to answer for.. except 3dmark 2005.. where games are concerned that compares well with real life.. memtest.. sandra and everest or rightmark dont..
a good overall system test would be 3dmark 2001.. its not just grfx card limitted..
but the only thing that i need PC power for is for playing games.. and even then it pretty much all down to the amount of system memory and the grfx card..
all my games play very smoothly now i have a card with enough grunt and 2 gigs of system memory.. they also load quickly.. even with cas 3 memory.. honest..
my system is software clocked.. i can change things with the click of a button.. i really can mess about and look for differences.. i know no one is gonna believe a change in cpu speed of 500mhz and a relative change in memory timings or speeds aint gonna show up in a game or general system usage.. but it dosnt..
