issit ram cooler a must if the ram is going to be bumped with voltage higher than 2.1V?
scare it will be burnt sweat.gif

If you love your rams, yes. smile.gif
Dude, use ram cooler la, you don't want to wait 3 weeks for RMA'ing your rams right? laugh.gif

Remember woh, the rams that you bought from me aa, the supplier is in the U.S. woo... tongue.gif

coz my area damn hard to find the ram cooler, have to buy from lyn bulker i think, the one moderno selling cost RM60 sad.gif
is there any cheaper alternative out there?
*
There is, ask allngap to built a ram cooler with a price of RM40 for you.
It is still on dual 60mm fan, but the fan is a lil' bit slower.

Eventhought it's a lil slower, it is still faster than most ram cooler you see out there. wink.gif

i wonder.. why DDR can support 2.6v but DDR2 with 2.4v will ruin the same 4 layer pcb...

is it becoz of marketing gimmick.. or irrelevant review..
*
It doesn't ruin the PCB lar, it'll ruin the chipset itself.
Since DDR2 chipset is originally built to run at 1.8Volts only. smile.gif

While DDR1 chipset is built to run at 2.5Volts. smile.gif

mean regardless the pcb got 6 or 8 layers..
or even the cheapo 4 layers pcb..
if the chips capable to handle the high voltage.. it's shouldn't be a problem right?

just need to handle on cooling method..
the problem is how to monitor ram temp.. lol..

Not really. smile.gif
PCB also plays a great important role in overclocking.

I'll leave this to the hardware expert to answer it clearly. rclxms.gif

I'm new to DDR2 but can't the crucial run at 1T? Noticed that in the timing tables, it is all 2T....  hmm.gif

Can, but that depends on which chipset on the motherboard you're using.
From what i heard, for LGA775. Only nVidia 680i chipset can go 1T. smile.gif

Dunno about any other platform. laugh.gif

Offcourse you can't see the Micron labels there.
This is because Team will relabel the chips to their name. smile.gif

For your information, Micron D9 DDR2 chipset comes in many different sizes.
Micron D9 chipset also has too many variety.

But, only three Micron D9 chipset that's confirmed to be powerful overclocker.
1) Micron D9GKX
2) Micron D9GMH
3) Micron D9GCT

Why don't you just buy those ram that is confirmed to be using Micron D9 chipset that is confirmed to be overclockable like the three up there? Instead of wasting your time looking at the chipset where you won't know either it's an "overclockable" Micron D9 chipset or not.
Example: Crucial Ballistix & Crucial Ballistix Tracer.

I'll list some of Micron D9 chipset that i know. smile.gif
* The one that is in red font means it's a Micron Fatbody chipsets.

D9CGH
D9CGJ

D9CHJ
D9CHL
D9CHM
D9CRZ

i thought single side chip is good for oc..
*
You mean single sided rams with chipset only at one side right? smile.gif
Well actually, it all depends on the chipset also.

If the chipset sucks in overclocking, one sided or double sided doesn't make any differences also.
So the most important things is the chipset itself.

Correct me if i'm wrong guys. notworthy.gif

PCB is important also, even cheap chipset if combine with Brainpower 6 layer PCB can also oc high lor.

No. You're wrong.
Even if u have a ram with Brainpower PCB 8 layers but with crappy chipset, it won't go anywhere.

The main important thing to find on a ram first is the chipset.
PCB is just a plus point.

QUOTE(rockmaniac85 @ Jul 18 2007, 10:05 AM)
guys, i would be getting the ballistix sooner or later, pc26400 800MHz.

jus wanna ask, is it safe to set Vdimm for this ram to 2.2V? somehow i feel like 2.2V is a little too high and probably could damage the RAM.. anyone can clarify this, as well as state the best Vdimm for this RAM? Thanx in advance..
*
Offcourse it's safe.
Crucial warrantied all Ballistix & Tracer rams at 2.2Volts.

You worry too much. tongue.gif

They have their own ways to discover it i think. smile.gif

Correct.
Anyway rockamaniac85, do consider yourself a ram cooler for all Crucial Ballisitx rams.
As they're hot. smile.gif

haiya, need meh? if i don't use ram coolers, it'll die faster ah? i thought u said crucial warrantied their rams at 2.2V, not lifetime warranty ah?
*
Yes they give lifetime warranty, but only if u use their ram at the maximum voltage of 2.2Volts.
If u use their rams more than that and later on burnt, and they know that you've been using higher voltage than 2.2Volts, the warranty voided automatically.

U don't know how hot is crucial ballistix rams, once you buy it, then you'll know how hot they are. laugh.gif

It's up to you either you want to use ram cooler or not.
But if you love your ram, that's the best thing to do. smile.gif

for voltage 2.2v or below, its ok w/o aftermarket ramcoolers (those with fans), but ramsink i think is a must when going above 1.9v, quite hot. 2.2v onwards better get active cooling or better watercooling for your ram. jz my 2 cents.
*
Not for Crucial Ballistix & Tracer rams.
U won't be able to withstand the heat of those rams even on 1.9volts. laugh.gif

They are hot!
Even on 1.9volts, u'll see how hot it is when you got a crucial ballistix in your hands. laugh.gif

Trust me, it's hot!
Yea your supertalent is cool, much much cooler than these crucial ballistix rams.

I bulk both rams, so i know which one is hot, and which one is cooler. smile.gif

anyone using Kingston hyperx 667mhz ddr2 ram ?
the higher oc achieve wat level ?
can hit 500mhz ?
*
No.
Hyper-X model lower than PC2-8500 @ 1066MHz uses crappy infineon AF-3S chipset which is not overclockable at all.

QUOTE(§layerXT @ Aug 5 2007, 02:37 PM)
HyperX sure can hit. maybe @ 55515. My friend's Team Elite also can easily hit DDR2-1000 @ 2v.
*
Do research before you post about things you're not really sure about.
Hyper-X models below PC2-8500 @ 1066MHz uses crappy Infinieon AF-3S chipset.

Even Hyper-x PC2-6400 @ 800MHz use AF-3S chipset too.

You want an overclockable Hyper-X rams? Buy those Hyper-X above Hyper-X PC2-8500 and above models only.
As those Hyper-X uses Micron D9GKX chipset.

Team Elite is different, because all Team Elite Rams uses ProMOS chipset that is proven to be able to run at 1000MHz, but at a relatively bad timings.
Not as good as Micron D9GMH @ Micron D9GKX @ Micron D9GCT. smile.gif
