Im using a socket 754 for my main box specs in sig. Ok I had 2x 512 of corsiar for awhile and have been able to run the CAS lat at 2. Now I just added another stick to make 1.5gb and now my system is not stable at 2. I can load windows surf the net and its fine, but as soon as try and load a game or any memory intensive program it blows up on me. After trouble shooting for a bit i discoverd that everything runs fine if i leave the lat at 2.5. I know there are issues like this for socket 939's with 4 banks full, is this a common issue with socket 754's as well with 3 banks? If so what kind of performance hit am i taking running at 2.5 as opposed to 2? Thanks in Advance.

Is the stick the same ram? Are you overclocked at all? Generally for overclocking more ram = harder, but i dont know of any reason why 3 sticks shouldnt work if they are all rated for 2, although maybe robberbaron or eclipse will if they see this thread.

Preformence wise, your getting no hit..........cas is a random number really, dosent mean much in terms of preformence........
it could just be the motherboard chipset, or could be your mobo dosent like 3 sticks, i know for A64's anything over double sided 2 sticks of ram will cause your comand rate to 2t, which prolly causes cas2 to cas2.5........really its nothing bad, if you feel the upgrade to 1.5 gigs is worth it...........play a few games or apps, see which feels better, dont keep in mind about the cas and such
whichever seems better stick with it

not just a common issue, it effects all s754 cpu's (the 1T/2T thing)R_sin said:I know there are issues like this for socket 939's with 4 banks full, is this a common issue with socket 754's as well with 3 banks?

the fact that you lowered your cas from 2 to 2.5 to make it stable is curious. i guess there's a reason for this:

Nope everything is stock.

Yup all 3 are the same. 512mb corsair XMS PC3200
