here we don't talk about performance, we talk about overclockability

here's some of mine....

DDR2-1034 CL4-4-4-13-2T @ 2.2V


DDR2-1004 CL5-5-5-13-2T @ 1.8V

If you use common sense, obviously you would want lower latency for better performance. It's not the matter of which one you should use, but rather which one you want to use.

dude.... obviously you need to learn to read the FUNDAMENTAL OF OVERCLOCKING thread instead of asking such basic/simple question here and there.

and stop posting new topic all the time.

Main discussion here is about DDR2... not motherboard. Stick back to topic guys.

yahoo! at last my am2 can memtest with actual timing display

increase little by little
up vdimm if not stable
use memtest or superpi32m to test
it's all basic
obviously you did not try to read overclocking guide nor the ram handbook

there are two characteristics of ram in response to voltage

1. responsive to voltage increament
- usually this type of ram rarely dies if you feed volt unless it far exceeds the norm. however the current ddr2 motherboards provide maximum safe voltage except for certain extreme boards. extreme boards are lame if you pair with cheapo ram. since it's just a DS4, it's just a 'enthusiast-friendly' board.

2. not responsive to voltage increament
- no matter how you feed the voltage your ram just wont go nowhere...not +0.1V... not +1.0v. these kind of ram dislike high voltage and most likely they will die if you overvolt it for too long

everything else is trial and error process.

it definitely looks like Micron. DDR2-667...prolly some random D9GCT

yup... probably it's higher binned since it could be the cheapest chips among other D9Gxx like GMH or GKX.

but well... that's just my speculation.

and for AMD ... anything above 1.5v the CPU-Z will show the default VID

some get worse result after burn in lol!

some chips just don't tolerate high voltage.

On AMD K8, it's almost unnoticeable unless you benchmark it.

For Intel, I don't know.

fatbody not fatboy

the reason why the thing is called fatbody because the chip is BIG and WIDE, and it does not have any gender (which boy or girl is out of the story )

anyway... that chip is FAR from being fatbody, it's not fatbody at all... that if you have actually seen fatbody chips

it's just the low end D9xxx, not that overclockable. quite rubbish i should say.

the chips are labelled as PSC

correct correct!

The only advantage of fatbodies is that it can run x-2-2-x latency, but at higher speeds, more or less just like the newer D9Gxx.

It's like BH-5 vs TCCD

i would consider those as low end rubbish, no where near D9Gxx

try to look for those 1GB Kingston... from my observation, a lot of the current batches use D9Gxx Micron... for example like 1GB DDR533 may use D9GCT, 1GB DDR667 may use D9GMH, and 1GB DDR800 may use D9GKX. But of course you need to look at the chips properly la.

there are a few revision of FP-Y5

I believe the Y5 code only indicates that it's a CL5 DDR2-667 chips. those typical ones will go to value segment while the special binned ones are for high end usage

my D9GMH only needs 2.1v for that speed
