Vdimm/Vcore mod for MSI K8N Neo2 PLatinum-54G Edition S939

**~~Shroomalistic~~** · 04-14-2005, 03:54 AM

I know this has probly been asked before but what bios's are you guys using to get your bh-5 so high. I did the 3.3 vdimm mod and I cant seem to get my ram any higher still. Im pretty sure its not the ram but it could be the mem controler.

can someone tell me all the vr's i would need to fully mod my neo2

thanks

I have just made the VDD-Mod, but sadly it didn't help me get any higher HTT or any higher HTT with 1:1 which i was hoping for

But it did help me with running dividers at higher HTT. Now I can boot with 270htt 166-divider, and that was imposible before.
I did put 1.8v through the chipset in 10min, and no problems accured so far

Like that 3.3v mod mate, looks great!

Just a couple things I wanted to clarify...

When you do that vcore mod, will the vcore show up in bios for adjustment, or should you measure with a dmm/dvom? Couldn't see an answer in the thread...

When using a ddr booster, should you set the vdimm as high as poss or does vtt track just fine no matter what, and just set to lowest and let the ddr booster do the work?

Also, I just wanted to give a HOOOOOOGE shout to all the guys and gals that put in all the hard work, time and money into making this thread possible. You should know, if ya don't, that it's VERY much appreciated

Cheers

Gray

I think the bios will show the 'correct' vcore, but you should still use a dmm always, never trust the bios as you know and the vtt will track.

Just need to ask, i dont want to blow my new mobo away.

And sry my crap english im from Finland

**kryptobs2000** · 04-26-2005, 11:49 AM

Yes, it will work, but what is the 'G-54 thing?' No idea what that is.

**ArcTan** · 04-27-2005, 02:16 AM

is there a vdimm mod like the gigabyte where you can use a vr to adjust the vdimm? hopefully more than the vio mod without having to mod your psu

**kryptobs2000** · 04-28-2005, 06:25 PM

There is can you take a pic of ur board, it's on the right side on the bottom... well.. if you look at it with the dimm slots horizontally anyways. I got a pic of mine on my camera, I'll put it up tomm, bout to go to bed, and don't wanna look for the drivers for my camera right now lol. If you wanna wait till tomm tho, I'll show you how. It's also somewhere on this forum, but it was kinda hard to find when I was looking before.

I 've found those switches in a Big eletronic components store. Down here in Brasil...

You mus search for a switch thar can handle 127V at 5A or 3A also works.

That's why it will need to to take care of the whole 3.3V current that cames from PSU.

Hi there,

I'm new here but I own a Neo2 Platinum.

I saw the easiest vddr mod here, that with the 3.3V direct connection.

1) What do you think, would my 2 x 512 A-DATA Vitesta DDR500 sticks withstand this voltage or shall I better NOT try it ?

2) What about cooling the sticks ? In the Neo2 Platinum, they run in dual mode only in slot 1-2, what actually means: there's a small 1mm gap between the two sticks, not more. Not even air circulates between them, so cooling both sides of both sticks is impossible in this setup. (One side of each stick can be cooled of course with small heat spreaders.)

**Eperkutyus** · 05-03-2005, 07:22 AM

One more question:

how much current does flow through this 3.3V mod's cable, leading to the + contact of the cap ? I have a 5K Ohm trimmer which are usually suitable until 0.5W power. Would it be a good idea to connect this trimmer in series between 3.3V point and the cap, in order to reduce 3.3V to about 3.0V ? (Would it burn out or may I do it without risk of damage?).

That's why I'm interested in the current flowing to the 2 sticks @ 3.3V.

(So I need NOT the voltage, but AMPERS ... milliampers .. sorry for my English..)

**Eperkutyus** · 05-03-2005, 12:20 PM

Nobody?

**$ilver** · 05-06-2005, 06:25 AM

the only thing that will happen is, that your adata will be killed ... there are Hynix D43 or D5 chips on it .. they don't like high vdimm anyway ..

**funkflix** · 05-06-2005, 07:00 AM

Yeah! Don't do it or buy u some cheap Winbonds.

I disagree, I have a GEIL PC4000 (DRR500) that can do DRR550 at 2.9v; however, right now I'm running them at 3.3v (cable mod) and no problems at all. Those GEIL got Hynix D43 chips and love voltage. When voltage is below 2.8v after ~260 fsb pass, Memtest fails after tens of #5 passes, so for yours sticks @Eperkutyus I don't recommend anything lower than 2.85v, even GEIL supports them till 3.1v

u will have unless 8A in 3.3V line so 1/2W resistor won't be enough. U coul try to find a potentiometer w/ 10W 2ohms...

You should read up on the Geil's! They make thier own chips, it's not a remarked anything, it's actually Geil chips on Geil memory. and they DO like volts.

So only do this mod if you want to kill the adata.

**funkflix** · 05-14-2005, 08:57 AM

Geil have no own ICs, they relabel them like all the others!

**Wittmann** · 05-19-2005, 10:13 PM

So if i make that 3.3v rail mod, do i need to care about the Vdimm voltage what i have set in Bios? Or i make the mod and vtt will track and i dont need to care about that bios setting?

correct BIOS settings makes no odds and vtt tracks.

**Wittmann** · 05-20-2005, 02:06 AM

Ok, so it makes no diffrence do i have set Vdimm to 2.85V or is it default. When i use this mod?

**PanaBob** · 05-26-2005, 02:50 PM

damn, went from a 20w iron to a 30w and it melted two of the traces away while soldering

I assume trying to test it out could fry my mem or CPU now?
