OCZ DDR booster 'droop' mod

[Rub87]

Why don't use one big decent mosfet, like the BTS240 or something..?

[Ubermann]

I run it without heatsink, but dont have a camera here.

[papatsonis]

can u remove for a moment and write down the numbers they have printed on the mosfets?

[Giana]

Have removed all the 4 mofos Will watercool them in near future. Got my soldering Work ready today, but i have to wait for some stuff.

I have 3 x :

D0046
NDP603AL

And 1 x :

D0022
NDP603AL

Perhaps i can do some pics later in the day. Digicam isnt avaible at the moment

[Rub87]

Hmm, be carefull to not make the wires too long, this will cause a non stable working.. keep them as short as possible, especially the gate one...

I get the vdimm from the software all along... anyone can tell me if I wanna use multimeter to measure the vdimm, which point should I connect? I'm using abit NF7-S 2.0

[Rub87]

Under dimm 3 you see a 8-pin chip, the 2 upper left pins are vdimm.. 2 upper right are vbt/vtt

the 2 upper left pins is for +ve ? what about the -ve?

[gsan]

what happen with the vdimm? from the AbitEQ and BIOS, i can see the vdimm is 3.60v but when i test with multimeter, it's only 3.0v!!

[Rub87]

Hmm, if you are sure that it is vdimm your software is reading way off.. wich is very possible, never trust software radings..

Here's the picture

instead of remove the original VR, i cut the these 2 line, it's equivalent to remove it from connected to the 12v rail:

Here is the short movie

ocz ddr booster

Here u can see my Booster
Well, cuase of the long wires i get a Voltage Drop under Load, but i will try the Droop Mod in near Future. I think i will get it work fine this way

Nope it boostes the Air

I was testing the A-DATA Stick @ this moment. And cause the booster was set to over 3.3 Volt for my BH6 i dont wanted to Plug it in

[msimax]

trying to get all the parts to the back using my redline 3500 i alway got errors at 900-1024md test 5 .i put a folded piece of paper in between stick two and booster and the errors stop so i said what the heck ..just got my neo2 back today and have a new booster .wont try that again

[Giana]

Can someone plz post a complete partlist for the droopmod ?
Would be very nice, so i can start next weekend with soldering

These are boards which the booster has been found to not work with:
MSI Neo2 (Nf3), however the same board has been found to not work with a un-modded booster, so there could be an issue between other components, and not the modded booster.

Dont understand this ... MY neo2 works with the Booster. Unmodded at the moment.

There was a problem between a modded booster and a neo2, where the board would refuse to boot with 2 sticks of RAM, but a few months later, the problem was found to be the booster itself, and was nothing to do with the booster mods or the neo2.

I've split the mod from the other thread to make it easier to find. The origional thread can be found here

[Quest For Speed]

I just completed the complicated version of the mod and it works great. Before I was seeing huge drops under heavy mem loads, now it is .01~.015.
Now all I need is the VTT fix for the board and I am good to go.
