Hi there, recently I bought a new desktop, and now i want to upgrade my RAM to a better one since i'm a gamer. Problem is i have no knowledge or watsoever on OC-ing stuffs.

So i'm here to seek advice as well as learn how to OC.

Currently my PC runs on
Core i5 2400
GB-Z68AP-D3
ASUS GTX560 DirectCu ii
KVR DDR3 1333Mhz 4gb x1

everything is running at fact default speed, no alteration made yet.

I was thinking of getting a G.Skill DDR3 1600/1866Mhz 8gb (4gb x2) performance RAM to boost the performance up.
And of course being curious as i am, i went and search knowledge about RAM timing.

The 1st google result i got and i read them, it says although RAM says the clock speed is 1600Mhz for e.g, but it wont perform exactly at 1600Mhz on default, instead in runs at standard 1333Mhz unless u manually OC it to 1600Mhz which is the guarantee max clock they can give on that RAM.

Later on, i found out that, to OC ur RAM, u have to OC ur CPU as well (or at least) to make them both have the same clock speed, that's what i understand.

So, I know i5/i7 CPU with no K at the back can't be OC-ed (wat forumer told me when i surveyed which CPU to choose), how do i utilize my RAM to its fullest??

Does the Mobo nowadays automatically OC ur RAM to run at 1600Mhz max?? or i have to do it myself??
Please, do teach me as i wan to learn

If i ever learn and does well in dis tweakings, i might considering OC-ing GPU as well coz i heard its possible, right??

since you oredy using Z68 mobo, why try not find used 2500k
btw you can just OC the ram alone without OC the proc.
just set the ram at higher divider. and you need to OC the ram manually,
afaik, no motherboard can OC the hardware automatically.

but its the best if you can OC the proc as well
intel (SB) love higher speed ram rather than tight timing ram.
just find those 2133Mhz ram instead of 1600.

you won't feel any perf boost by using 1600Mhz ram.
*inteL Pro : correct me if i'm wrong as i'm intel noob..

i see i see, then how about me saying dat higher performance RAM such as 1600Mhz - 2133Mhz wont run at its maximum at stock unless u OC it?? Am i right about it??

2133 honestly is a bit costly and many forum advice gamers to use 1600 since 1866 onwards are for graphic processing or watever i not sure oso. at max i can afford 1866 only for now since budget tight

9-9-9-24(or27) is pretty good right?? no need to tight up the timing and just boost up the speed...need someone to advise me wat value, multiplier to put with my setup

all ram will run at default 1333Mhz even you use 2133 oso will run at 1333. we need to OC them manually.
how much is your budget. winova xtune 2Gb 1600 is one of the best ram but the price is affordable.
you can OC winova xtune from default 1333 CL9 --> 2133 CL9-10-9 with 1.65vdimm or even lower voltage

p/s : if you not intend to OC, just add 1 more KVR 4gbX1, can save your pocket money a bit

dude seriously 1333 to 2133?? is it safe?? LOL

my budget was set around 300 max, planning to go for 1866Mhz G.Skill RipJawX 4gb x2 wan...
then u asked me why not go for 2133 i was like and surveyed even more...

lets say i got myself a 1866Mhz wan, i can OC it to 2133 also right with my current setup



I keep mentioning G.Skill not because i fanboy it, just because dis and Corsair are sold more on garage sales=.= i'm looking for a reliable RAM with the lowest risk of getting problems, and also easily RMA-ed incase things do go wrong

1. winova xtune is 1600 CL11 but running 1333 CL9 at default. noted that any ram will run 1333 at default speed
(correct me if there's any ram that can run at rated speed ; 1600, 1866 without OC)
most OC ram rated at 1.65V, which is the max safe volt for intel setup iirc. it is most safest if you can find a ram
that can run at 2133 CL9 with below than 1.65Vdimm, and the price is sure not cheap
for AMD setup, 1.65V for the ram is normal


2. RM300 can get xtune 4GbX2 edy. mybe can run 2133 CL9 at slightly lower voltage compare to cheap ripjawsX
ripjawsX 2133 with CL7/ CL8 or even 1600 CL7 ripjaws is not cheap.

3. if the 1866Mhz was rated at CL9 @ 1.65Vdimm, i don't think you can run at 2133 CL9 with 1.65Vdimm
unless loose the timing at CL10. or if the ram has a good chip, yup you can OC it to 2133.
noted : no points running the ram at high speed but at loose timing.

4. yup your PSU is more than sufficient. your system consume 380W only at max load iinm..

you can ask Cyntrix about the gskill ram.

LOL exactly, i saw his thread and am considering getting the either Corsair/G.Skill 8gb 1600Mhz running at 9-9-9-24 or 1866Mhz at 9-10-9-28.

if i go 1600, i can actually OC it to 1866 with the same timing or possibly lower right??

if the ram 1600Mhz CL9 rated @ 1.5Vdimm,
1. maybe can OC up to 1866-2133 with 1.6X Vdimm
2. 1600 CL8/CL7 with 1.6X Vdimm

if the ram 1600 CL9 @1.6V/ 1.65V, mostly cannot go up...
thats why i say find the ram that rated at lower timing or lower voltage (1.5Vdimm)

OC is not only care about speed bro, you need to care about the voltage too.
ram with good chip can easily set at 1600 CL7/ 1866 CL8 at default voltage 1.5Vdimm

well, i refer to his thread http://forum.lowyat.net/topic/2051436

both 1600 and 1866 are running at 1.5v
gskill's 1866 runs at 9-10-9-24 timing but corsair's 1866 runs at 9-9-9-24, 1.5v as well.
But how do i know if their voltage will increase if i OC them??

can u tell me wats the priority?? timing or clock speed?? i know timing is the delay it has be4 reading the next data right??

let's say, is a 1866Mhz @ 9-9-9-24(possibly CL8) better or
a 2133Mhz @11-11-11-27

kinda confuse wat comes 1st

condition :
proc = stock clock
ram = 1866 CL9 OC to 2133 CL9

stress test using prime/ linX/ run bench such as superPi 32M.
if not stable, then we need to increase the vdimm by 1 notch, depends on mobo
some mobo as small notch (1.5V + 0.01), some has big step (1.5+0.05)
increase the voltage step by step until stable

some people tell me SB's priority is higher speed but i still prefer both ; high speed and tight timing.
2133 @ 11-11-11 is too loose..2133 9-11-9 i acceptable. else, better run 1866 CL8/ 1600CL7

i see, i oso tot going 1866Mhz would be better, but GSkill's 1866 is 9-10-9-28 and Vengeance is 9-9-9-24 but a couple 10's more expensive...if take gskill's, can the timing be decreased further??

Now, i need a sifu to teach how to OC it based on my system config. Know nuts bout OC stuff

if u are afraid to OC get a latest mobo with UEFI bios..its easy to OC

if u dunno how to OC u can set D.O.C.P its recommended OC setting

na automatic OC is not an option for me, at least not anytime soon, my new rig is oni weeks old takkan purposely buy new mobo meh

and i wan to take dis chance to learn how to OC too, a skill i can use in the future if i ever get a new system.
if u refer my 1st post, my current mobo is GB-Z68AP-D3, i still don know wat it can do for me when comes to OC.

try this link http://forum.lowyat.net/topic/1709431
OC on P67/Z68/Z77 + sandy bridge proc

THANKS!!!

will ask question if i stuck again

great help from u but then i still thinking whether to get a 9-9-9-24 Vengeance or 9-10-9-28 RipJawX both 1866Mhz...
wat u think?? RJX cheaper of course...

because the thread is using Z68 mobo. take your time to explorer it
i oso wanna explore it this weeks since i have Z68 mobo + i7k to play with
i'm intel noob btw. 2nd time wanna play with SB

ohhh okok, will explore when got time =) thanks ya
