soon will upgrade my pc to c2d spec. need some info whether is it any of the
Corsair 1GB DDR667 ValueSelect model easily OCable to DDR800?
if no, maybe think about go to XMS series.

very appreciate to someone here can share your info. thanks.

That depend on what kind of chipset it uses...

If it's using Micron D9, then i think oc'ing it to a DDR800 won't be a problem...

I got it. thanks for your reply.

All Micron DDR2 is named D9... but not all D9 is overclockable. D9 just indicates that it's DDR2 from Micron.

Overclockable Microns known so far are those of D9Gxx or D9Dxx.

D9Gxx is square, I mean really square, not rectangle or oval or heck not even round.

D9Dxx are the old ones, they are big rectangular chips which looks like DDR, but they're BGA, not TSOP. They are BIG RECTANGULAR chips, not small rectangular chips, and they're obsolete from the current production line.

Other Micron DDR2 cannot be considered overclockable, they even barely reach DDR2-700 sometimes.

For Corsair VS i dont think so.. i used CVS b4 and i sold it becoz its not good in OC. When u oc to 800-1000MHz, the lanterncy is so loose.. like 5-7-7-20.
Better get any Kingston VR with Hynix chips. Can OC better than CVS with lower lanterncy.. CL-4 i think.
Moreover Corsair chips is all relabel one, i hate tht becos we dunno wht chip we are buying.

Wao nice info for me.. Thanks soulfly

great to see your replied, yehlai and soulfly.
good info for me too.

I would had said, depend on wat chip on it and yr luck. If U are lucky, U can clock above 800Mhz with ease. I got a pair of Corsair VS running DDR8002 4-4-4-12...running 24/7 on my previous setup.

Corsair VS = Need a lot luck, becoz their chips are relabel.
Kingston VR = Just choose the Hynix chips, it perform good.

Last time my CVR using micron chips too, they said got brown dot at the corner of the chip. Buy o'c result so-so only. Moreover.. cant see wht chip they using, only can see brown dot.. not reliable.

i using 512 mb kingston VR 667 * 2 ....n now running 800 at cl4....

Hynix chips?? not bad.. tried 4-4-4-12 or 4-4-4-10 ??

just received micron ddr2 4200u yesterday & the chip were d9dgk

havent test any higher than 400Mhz yet, but im wondering is micron chippy need higher vdimm than hynix c4?

1 is hynix , another is duno wat la...sms??
em..trying at 4- 4- 4- 12 onli....

I think 800Mhz can use 4-4-4-10.. coz its just mild o'c for hynix 667

my 895 can't go lower than 23...

U mean your Corsair xms??
895Mhz timing is wht for now?? Try feed some vDimm

Bang on target.

forgot to do tat... but the 1st was 4 and the last is 23...

To those of you running the KVR 667 @ 800, whats the voltage u use for it? 2.2 or 2.3? Hopefully its lower..

Btw, if oc KVR upto 800 level, need active cooling or not?

if u can add active cooling...
but it ok to hav good air ventilation in ur case....

default vDimm is 1.8v.
800Mhz i think should be 2.1v or less.
