Well what does it do!.....

First of, let's take a look on some things.
Today we need more and more Ram into our computers....Not enough the 2 x 512MB any more....
Now....Motherboard manufactures give as more voltage than past....

Let's say a manufacturer gives 2.4Vdimm max through bios....When he designed his motherboard, he kept in mind to give more ram power, so he placed the proper circuit and the proper output power Mos-Fets for it.....
He gave a bit more voltage too (2.4Vdimm).....Calculating all these amperes with voltage and the current the ram modules draw, he did well.....BUT....Here comes the "BUT"....He didn't have in his mind that some "crazy" people (like us) will mod(modificate) his motherboard so as to reach even 3Vdimm.....
Keep in mind that the more voltage we feed the rams, the more current they draw......ALSO raising the Vdimm, the current of the rams raises logarithmic.....
Example: Let's say that our rams at 1.8Volts draw 3A.....At 2.4Volts they will draw 9A and at 2.65Volts they will draw 14A.....NOT to mention what they will draw at 2.85Volts..... OR if we place 4 x 1GB ram modules in.... Very Happy

In real, 2 x 1GB DDR2 ram modules at 2.65Volts, draw 14A - 16A at full load which is about 40 Watts.....
4 x 1GB DDR2 ram modules draw 80 WATTS....In this case we need a VCore circuit for the rams and not 1 or 2 "tiny" Mos-Fets.....One reason that when we overclock 4 x 1GB ram modules, they don't do well at all, it's because our mobo just CAN'T supply them enough.....TOO MUCH load for it, EVEN at 2.4Vdimm.....

In such a case we "press" TOO MUCH the onboard Vdimm circuit and OUT of it's limits.... Wink
If the manufacturer has made the "mistake" (not mistake for him though) and hasn't placed at least a heatsink (which is not enough though) on the output power Mos-Fets, then 2 things (or more) are taking place:
a. TOO much heat on and near the Mos-Fets, which little by little spreads around the motherboard,
b. TOO much fluctuation of the Vdimm voltage
This means that the rams COULD NOT reach their frequency limit because we "stop" them by the fluctuation of the Vdimm....

Now here comes the DDR Maximizer to "help" the mobo(motherboard) by:
a. The ram modules draw ALL the power they need from it and NOT from the mobo which results in a COOLER mobo (and perhaps avoiding of blowing a mobo's output Mos-Fet from heat and "pressure") and
b. STABLE output Vdimm which results to push our ram modules to their REAL limit by providing ACCURATE output voltage and VERY well filtered as well..... Wink

When we plug the DDR PCB into a slot of a mobo, then our ram modules draw ALL the current (power) they need from the DDR Maximizer and NOT from mobo....

Straight from Hipro himself the benefits of the Maximizer http://www.hipro-tech.com/forums/viewtopic.php?t=8



So basically, higher vdimm voltage options with more stable and ample vdimm voltage to memory modules bypassing the motherboard (cooler motherboard).
