Corsair Dominator PC2 8888 or PC2 9136

8888 is 4-4-4 cas and the 9136 is 5-5-5 cas latency...... but with higher clock

seriously need to know which one is better

Well, heres what I know. Corsair 8888 cas4 is top memory, the stuff taht does not pass the strict binning for the 8888 cas4, will be rebinned for the 9136 because they will run higher speeds (mhz) at looser timings. 9136 is the stuff that does not make the 8888 binning.

So in summary.

8888- 1111mhz 4-4-4-12 (their flagship ram. highly binned, hand picked stuff)
9136- 1142mhz 5-5-5-15 (the IC's that dont pass the 8888 qualification become this, and also only guaranteed speeds on 680i Platform)

Either one is going to be really fast and you only really need that for OCing, but again with RAM buy the RAM thats guaranteed for the speed you would like to run then you'll be OK.

Also keep in mind the faster RAM is usually just the same as the slower stuff but certified for higher voltages with looser timings or whatever... so you pay for the company doing all the OC guesswork for you I guess

Dom 8888's have lots of headroom and can easily reach DDR2 1200-1300mhz

The 9136's cant as easily.

ended up getting the dominator 8500 1066mhz 5-5-5

The Dominator 6400C3 are better than the 8500's fyi

better overclockers? i think my mate has it running at 1.2ghz atm

6400C3 will boot DDR2 1000 at Cas3 ^^

At what kind of voltage

The stated 2.4v will boot Cas3 on any stick I have used of it. takes about 2.5-2.6 to pass memtest

Isn't that a LOT of voltage for DDR2?

I know most OCZ DDR2 sticks are around the 2.0V - 2.1V mark and they're on warranty but I don't know who in their right mind would warranty that kind of voltage without some form of active cooling

Corsair fully backs their Dominator Modules that come with fans for a rated 2.4v from them directly. Its only for the dominator modules containing a F in the part number as they come with the domiantor airflow fan.

As seen in these pictures, its rated 2.4v from the factory. As well its fully backed if they die at 2.4v Well actually the voltage isnt listed on there but heres a link. Also the Dominators were specifically designed to be used for high voltages and performance they come with a fan if you buy the highend dominators. Heres the PDF link

http://www.corsair.com/corsair/produ...8-6400C3DF.pdf

granted all their highend dominator from 6400C3d all the way to the 8888C4d is anywhere from 450-700$ for 2gig matched pairs. But its well worth it imho.

I could never justify spending that much on RAM :|

Hey isn't that the RAM that comes with the watercooling tubes preinstalled or am I thinking those new OCZ modules?

Watercooling ram... ridiculous

OCZ buddy

Maybe if you get the water cold enough it might live, but 2.5 is still extreme.

Heres this if it helps,

Quote:

Electrons in one transistor are not supposed to be able to reach other transistors in normal circumstances, but according to the principle of quantum tunnelling, an electron can actually escape from an infinitely deep energy well; it just does not happen that often. A transistor is made up of positively and negatively doped silicon around un-doped silicon. Every now and again, through chance alone, an electron can tunnel away from the conductive silicon keeping it in place. Usually it will only burrow in a couple of atoms and then return, though sometimes it can travel into another adjacent transistor. This does not normally cause a problem, because you need a lot of stray electrons to cause an error in how the gate is read. The problems start to occur when an electron attaches itself to one of the silicon atoms in the un-doped section of the silicon, or knocks another electron out of its orbit. This is known as silicon degradation, and over time, usually measured in years, a path is formed by the damage caused by these tunnelling electrons between two gates. Electrons can then flow across the junction freely, causing it to malfunction, and the value be misread by the computer, resulting in an error.

The more energy an electron has, the more likely it is to tunnel, which is why if your CPU is running hot, or has a considerably higher voltage going through it, electrons can tunnel through far more easily. All CPU’s are built so that there is an inbuilt resistance to quantum tunnelling for an extended period of time, but when you overclock your CPU, that period is reduced.

If you overclock or over-volt the chip too much, you can actually physically destroy the silicon lattice of gates within a processor.

Just a small note at the end for temperatures.

AMD 90nm Users: Keep those CPU temps below 55 degrees Celsius. AMD mobiles can go higher.

Intel Northwood Users: Keep those CPU temps below 55 degrees Celsius.

Intel Prescott 90nm Users: Keep those CPU temps below 65 degrees Celsius.

Intel Presler 65nm Users: Keep those CPU temps below 60 degrees Celsius.

Intel Core 2 Duo Users: Keep those CPU temps below 60 degrees Celsius.

Granted its taken from Overclock.net and was written by a guy that uses very sophisticated language, and makes very lengthy posts on stuff that usually has wrong information. But he is at least right on this one.

Yeah but unless theres a wall or thats the barrier point, .1V isn't enough to cause significantly more damage I don't think. If 2.4 shortens lifespan then the lifespan will be similarily short at 2.5V
