oh wait, i don't have mixed ram. both pieces (4gb x 2) are KVR and both are 1333mhz. the vengeance 1600mhz is a separate question all together. i just think that it's value for money, although if there's no noticeable performance increase compared to my current KVR then i wouldn't bother upgrading.
ok lags such as
1. once i type in my password, it takes really long to get past the welcome screen, like 5-10 mins. even 15 mins at times.
2. once i get to the desktop, it again might take a while (5-10 mins) before i can start clicking any icon or the start button. if i do any of these, the comp will just freeze.
3. i get frequent hangs when multitasking, which i have not gotten before say a month ago.
4. there have been one or two instances where my dram led comes on (again in the last one month where this issues started surfacing) and i can't start my comp up although that hasn't recurred for at least a week already.
why i mentioned about my pc running louder than usual is because when i do normal stuff which don't stress the pc at all, like watching videos or surfing the web, the PC used to be really quiet - to the extent that the fans aren't audible from 2-3metres away. now, even doing normal stuff, i can actually hear it from the other room? and yes, i've checked my cpu fans, gfx fan and processor fan is still in place too - all working fine without any obstructions. cleared the dust by cleaning the fans too.
