Overclock 4 modules

[MoonL]

i have one kit of Kingston Hyperx Blu 4GB (2x2gb) at 1600Mhz . I want to buy one more kit - same type of memory ram . Total 4 modules ( 4x2gb ) at 1600Mhz. I want to overclock them at 1866Mhz for my AMD A8 6600K to get better performance. This is ok ? Is ok to overclock 4 modules ( 1600Mhz) at 1866 ? My sistem will be stable ?

Can try, any time you mix sticks from different packages it can be problematic....DRAM is packaged in different amounts of sticks so they have been tested to work with each other. Normally if 1600 or 1333, even if they don't WANT to play nice and work together they can be set to, with a little extra voltage and maybe a timing change....and generally OCing DRAM is not all that difficult, but here you would be mixing set, which would possibly take extra voltage and wanting to OC which takes extra voltage to do so effectively....Believe most all of the 1600 Hyper X sticks start at 1.65 (which is way to high for 1333 in the first place), so you have no real room to add voltage even to get them to play together let alone OC realistically.... Most ALL 1600 sticks adhere to the the JEDEC standard of 1.5 volts, having 1.65 is usually indicative of weak ICs (memory chips) so chances would not be good, prob not impossible, but I wouldn't chance it....Be better off getting a straight 2x4GB set (and if at 1600 or 1866, a 1.5 volt set) generally with good DRAM won't see 1.65 unless they are 2133 or better sticks

I already have one kit (2x2gb) and i want to buy another kit ( one more kingston hyperx blu 2x2gb to fill 4 slots , same memory type ) . I know a person who overclocked this kingston hyperx blu1600Mhz over 2000Mhz but with one memory kit (2 modules) . I want to know if i can overclock 4 modules at 1866. One more think - i want a stable system .

Without having it in front of me, yes it's possible, but as said if these are 1.65 I wouln't even bother trying, taking the voltage over 1.65 could damage other components and with no idea of the actual DRAM model, your mobo or CPU it's even harder to guess

i saw on a site - this memory kit - at 1333Mhz they are at 1.5v .
Do you think the will work ok at 1866Mhz and 1.65v ? with 4 modules

So they are 1333 not 1600?

They are 1600Mhz memory . At 1333Mhz they have 1.5v . At 1600Mhz i think they have 1.65v .

i saw on different sites - this memory are good for overclock (over 2000Mhz) . But they overclocked them with one kit ( 2 modules ) . This i want to know. The number of modules matter in overclocking ?? Do you think with 4 modules i can get 1866 Mhz ???
