Hi kyosen. With this info, I should be able to get step 2 completed this evening, with results tonight/tomorrow. Your tips are greatly appreciated. :toast:
With the direct 3.3v from PSU mod it's possible to use the DDR Booster to increase/decrease a bit more the voltages?
Can someone post some more pics with vcore mod only?
With the Booster and 3.3V, you could possibly raise the voltage, but you would also be feeding that back directly to your 3.3V rail. Not a very good thing to do. There is no way that the Booster would decrease VDimm below the voltage supplied by your 3.3V rail though.Quote:

I soldered to the +ve pin of one of the caps. Did this from the underside of the board. If someone could take a photo of the underside of the board I will mark it up showing where I soldered (no digital camera here)Quote:

Great Job Man , can you take a macro photo of that are ?
Cumps
Edit :
Why is that wire so long ?
I was reading that is dangerous to have a so log wire :S
Is there a conection by the front to connect and disconnect the mod ?
I need help about vcore....
Please see this post:

I'm from italy, so, first of all sorry for my bad english.
I read all the post, but I'm a little bit confused. I've no problem on soldering and cutting trace, but I would like to be sure about what I'm gonna do.
The last mod that I dii was on a DFI infinty and on this board to rise the voltage saw by the ram (actually I have 2x512 mushkin leve 2 that run 270 prime-stable 2-2-2-5 with 3,5 volt ) I had to do the VDIMM mod. On the DFI mobo the vdd mod was mad to increas the northbridge voltage.
Here I understand that the VDIMM-VIO mod is needed to set the ram voltage at 3,3 volt fixed value.
Vddr is the value that is saw by the ram? (BTW is the value that I want to pusch to 3,4 - 3,5 for my bh5?)
But what mod I have to do to permit me to adjust the value of ram voltage?
To increase the value of the vddr, I have to increase or decrease the value of the trimmer?
How the step 1 and step 2 works? Is possible to do just the stp2 to have the chance to set the ram's voltage at 3,6 - 3,7 ?
Should be possible to do the VDIMM-VIO mod to get the 3,3 fix value and than make the step2 vddr mod to increase the value untill 3,7?
Thanks for answer
Does anybody know the vdimm reading point? My ddr booster leds are burn...

Can you help me ?
Thkx a lot guys [[]]
Normaly 245-260MHz with BH5! :) Maybe ur Board sucks?!
Not the board maybe the mems , at the k8ns also 225/230 was the top oc , maybe doing something wrong in the bios ,
what ram config are you using ?
166/2.0-2-5-2/1T ; Aggressive Timings = Disabled ; 9 x 2xx/3xx.
Going to try that :D
Wish me luck :D
Edit :
Forget what i said :D
I got this now that i´m waiting for ocz powerstream 520W

Nice idea with the fanheader, i forgot that... :)
Fanheader is not the on/off, just the base for the on off (done it with pins from a dead p4c800 and an old cdrom jumper ;) )Quote:

Anyone recomend other bios?
Don't know were i read but there's a 1,5beta bios somewhere dunno if improves anything...
When i put 2,85v for the mem's in bios (max available) when i read the voltage in the reading point (using a grabber to do that) i read 2,70v...where are the others 0,15v lol ????
More weird than this is if i put the mod on, for example, 3,5v when i turn it off the multimeter reads 2,85v for 2, 3sec...but after that shows me the 2,7v again...
Any idea on this one????
Thks in advance ;)
Hmm, i prefer 1.36b for high Vdimm and BH5, but if it will fix ur Problem, dunno!?
Here is all fine no prob with the voltages! Maybe the mod don't work that good
as it should?! :)
wheres the test point for vdimm guys?
The mod works perfectly Gravedigga i can raise it till my psu shutt's off, almost at 3,9v...it's an enermax 465w with all rails modded...i will try the 1,36b later...Quote:

Anyone have done the Vdd with success? if so please post piccies.
Cheers,

yes , if someone has done it , plz post px, also , -cause i have the pc assembled and "closed"- does anyone know which one is the small regulator , to which the vdd mod is applied?, above the marvel sata-chip ? cause i want to find the datasheet , i cant see clear from 20cm away , but i see somethig like A235 , and i cant find a damn datasheet of it ,
These are some pixs of my mod. The advantage is not to void your warranty.

More details: Apply a layer of double sided tape, then connect a wire into (+) leg of the capacitor. Wired it through the mounting hole, and then connect to the 3.3V leg of PSU jack. Apply another layer of double sided tape onto the wire for protection. Finished the mod.
PS: Damn my bad English, hope ppl understand what I said.

If you are wanting Vdimm=Vio(3.3v rail), you need to connect the 3.3v rail to the +Ve side of the capacitor that is in the Vdimm loop.
And don't take the +12V Pin like i've done @ my first board! :D

Anyone know how to do Mosfet mods, etc. It seems like there are lots of solder pad open for additional voltage regulation but I have no idea which one to touch. As for CPU cap mod, which cap is the one for CPU?
:D
256MB BH6 and the 3200+ Winchester dies, but the Board still rocks! ;)
@No Mercy:
Re your post with pic http://xtremesystems.org/forums/show...&postcount=128
is that wire completely bare? Whis is that? Thanks.
are you saying you killed a 3200+ with this mod?Quote:

As I dont have time to read the entire thread again, can someone tell me what regulator is under the CoreCell sink?
Its named MS-6 49376R8FQuote:

That's just a intersil chip like the HIP ones that's for the Vcore easy mod alot of boards are using it these day's got the pdf datasheet somewhere for that.
Pin 10 to Ground if I remember right...
VDD is correct power trace from chip leads back to the leg of the Mosfet outlined for VDD its not VDD lack of power holding things back :(

lol saw the isl chip did not twig to the chip at the side.
I'll have a gander...
the one circled in yellow seems to be a hip6601 chip.
How many of them are present on the board around the socket?
As far as I can tell 1 * 6601
And.. 1 * 6602 can't see any others
That said there were some mosfets on the underside of the board, can't remember if any other IC's existed.
Boards all mounted in so can't do much much hunting around until tommorrow.
Interesting... the "VDD" mod doesn't do sqaut on this particular board i have (which i replaced thinking this is the better one... the one I sold in fact was much better... blast me).
However, I did notice some gain when I previously modded for this. (About 10-20mhz more FSB overclocking). What is this actually feeding? Curious and curiouser.
Seems like my chip is held back by the HTT limit of the 0440A2 Taiwan chipset :( Any freaking working VDD or what?
VDD might help might not. Only way to find is to try. I suggest you get few micro grabber with resistor and use it :)
jinu117
I have SMD grabbers in the mail. So is it the one posted here? Does the NB chip get mighty hot?
The moronic layout of this board doesn't really allow to improve the NB cooling @ all.
Hey no mercy I'm very interested in doing the vdimm mod that you have picture of. I just need couple more details and a pic of what capacitor that you have connected it to.
Plus what type of wire I need?
Seems like my chip was limiting my HTT, so I won't be doing any mods on the board just yet.
:stick: lol nice Nforce2 you got there
this makes me think there are about 3 or 4 empty spots on my DFI infinity that i could put some caps on..
im out of town for a week but im definetly trying this soon.
There are a lot of boards with "empty" places for add some caps that helps sometimes a lot :) ...i remember the canterwood and springdale from asus...Quote:
Originally Posted by Revv23

Can u give tell us differences before and after the mod...the 3,3v = vmem is obvious but the vcore...more mhz or only more stability?
Other question, when u tell that u are going to change the rest of the caps how do u know about the correct value to improve the stability?
Add more cap's of the same value on empty places is one thing but changing the present one's by others with higher values... just don't wanna see caps jumping of your board :)
I stuffed mine with 7 3300uf caps...runs without problems so far, but i can't say yet if it's more stable now...will test it when my new cpu arrives.
Anyone knows where to messure the Vcore? :)
whats a good way to unsolder this stuff from my old mobo?
You know the four caps that are lookated to the left of the 7:n 1800ufs caps. Is it nessesary to change them to maby dubble capacity?Quote:

Did I miss it, but is there a picture for the vcore mod? Thanks.

Some of the Fets on the nearby area shoul give the same voltage, but you must test one on one to find out cause I don't remember wich one at this time.
Someone please to answer...Quote:

Err...yet it seems to run 2500Mhz on 1.47v, it crashed once, but it may have been due to to memory timings...and it runnign really really cool, so im beliveing it is running lower volatge..

since its 1.4v stock.. my temps look good an its runn good..
For "normal" overclockers... is it safe to do the vdimm like this?

Hi, I'm currently running a Winchester 3000+ at 295x9. BIOS is set to 1.55V+10%, CPU-Z says about 1.61-1.63V under load but I'm reading 1.39V idle and 1.35V load from that mosfet! :confused:Quote:

[Edit] One more thing, using clockgen I can set the VID to anything equal to or below 1.45V but anything higher (goes up to 1.55V) and it just stays at 1.45V. Strange.
that just makes it 3.3v right? I was thinking of getting a DDR booster but my memory like 3.0v, (TCCD) so i was thinking ill try a 3.3v mod and see if it likes that, if it dose ill go with it.Quote:

what do you mean you can change the PSU 3.3v line? Your talking about a sence wire mod right? Not in the bios?Quote:

I jsut didnt understand what you were sayin..
For the VDD mod, there are 2 solder pads for both the red and brown wires. Do I solder the wires to the pads closest to the SATA ports or do I need to bridge the solder pads and attach the wires. It is hard to tell from the picture.

And here You can see the Mod for the MSI K8T Neo2-F done for a friend of my.
http://home.tiscalinet.ch/respawn/wh...2/IMG_0012.JPG
U can see, i soldered direktly to the RamSlots. Will this work for the K8N Neo2 too, or have I to use the Capa Mod ?
i've done the one on the first picture and it works great :)
One other question ... i have read the K8N Neo2 tips and tricks guide .... there is an informnation wich is telling me the OCZ Booster will work to 4V on Slot 4
The OCZ Homepage just tells me the Booster will only work to 3.4V for this Board.
Wich information is correct ?!?
the one here of course :P
this board tracks the vtt correctly,so theres no problem on it
_zZz_
I've got 2 questions:
1) Pot for VDD mod should be 20k right? To increase voltage I need to lower the resistance?
2) Can I use JC11 (chassis intrusion jumper) to plug my 3.3V vio mod on it? So I can turn it on and off.... using a jumper :D

Hey ! Is there anyone out there who have made this mod on a MSI K8TNeo2 -F ?
Or any simple guide to do a vdimm mod on a MSI K8T Neo2 -F
may i know how to get vdimm reading on multimeter for MSI K8N NE0 2?
thx
Maybe u should try to read the Thread .... ;)
it is the JC11 on the picture measuring point for Vdd
both multimeter probe on the pins or red on the either one & black probe on casing
thx
Red on the green Point Black on Case or any other Ground.
thanks bro...
