Checked it with a scope, seems verry good..!
It coulb be me, as I don't know how to use the scope properly but from what I can see, the generated current is much more stable than the psu's +5v rail..
The line on the scope has much verry little up's and down, but they're very small, about 1/20 of a div and with div height @ 0.2v, while the +5v's ups and downs are almost as high as 2 div's (0.4v)
I can't go lower than 0.2v/div and the div lenght is 0.02ms
As cap I used 1µF...
Was that under load or at idle (I assume it was under load)
Load,
254fsb 11-2-2 2 is primestable in single channel, dual channel 220 isn't even stable..
I noticed that when runnen prime95 @ 255 fsb, 3.5v, the fluctuation is a bit higher, any ideas how to make it smoother?
Got video, this is under P95, 1 stick BH-5 @ 255 fsb, 3.5Vdimm, using 1µF as capacitor between the scope wire and vdimm...

Are you running double sided or single sided sticks of RAM?
You could try adding a capacitor directly accross the output of the Vdimm MOSFET, and a choke in series with the Vdimm output, and a capacitor after that, on the RAM side of the supply to form a PI filter which will help to filter the supply.
Single sided...
What is meant by a choke?
Chokes are the round ferrite rings with thick copper wire wound around.
I haven't tried the chokes yet, but with 2*256 BH-6 dual sided sticks (corsair xms pc3200 rev 1.1) I have 245 stable dcddr @ 3.5v...
Any idea why this isn't possible with BH-5?

Also I noticed that with pair multipliers (5,6,7,...) I can go much higer than with unpair multipliers (5.5,6.5,7.5,...) any input on this issue?
The problem with the multipliers could be related to the BIOS. I'm unsure as to why the BH-6 is clocking higher than the BH-5, but it could be related to CPC.
Different RAM will clock differently in the boards too. I could only reach 235 stable with 1*512 3700 EB, but with 2*512 TCCD I could get up to 245+ stable (was prime stable at 245 with both the EB and TCCD, but I wasn't 3d stable with the EB)
Bumping this thread I got some high res pics of a booster
