Looking for MSI K7N2 delta-L vcore mod! !

This mobo doesn't leave to go over 1.8V vcore!Does anyone know something to do about it?Any guide would be helpfull!

Can you post a pic of the board so we can see what Vregs are present.

I am sure once we point out a few things for you to read to us that we can figure it out without to much effort I am hoping.

Hi i also have this mobo and was disappointed with the 1.8v limit even though these boards overvolt by 0.05v, the memory voltage is also limited to 2.7v but 2.8 volt can be had with a modified bios. This board has a HIP6302 voltage regulator shown in the pic below, i think you could attach a 50k variable ohm resistor to pin 7 (on the topside of the chip) to increase voltage.

Could anyone see a way to increase the chipset voltage by looking at this pic a vdd mod is badly needed for this board, most people trying to oc are stuck at around 215 fsb.

Yep. pin #7 is the Vcore.

What are the markings on the chips I circled?

These are the marking of those ic's.

hip 6602 bcb (this is the one next to the hip 6302)

4410a
*23cp (these are the first 2 ic's next to the dimm slots, *= a small triangle)

6520
acb
p301avy (this is the third ic down)

I am thinking that the 6520 ic is the same as the one used on the abit nfs, therefore connecting a 10k vr to pin 6 would give the ability to increase voltage?

[Hell-Fire]

The HIP6602 is the "driver" for your Vcore circuit.

Modding HIP6302 on pin #7 is the right way to go as you thought since it has main control over the circuit.

Thats interesting that they mounted the 6520 IC by the dimm sockets. Yes, pin #6 to #4 with a 10K is the mod. But I would first find out which of those FETs are reading the Vdd and Vdimm. You would want to check each of those after the mod to be certain which you have modded.

Is the triangle sideways to the numbers, or right side up? Is it just a solid triangle or is it made out of letters? I am trying to find that data sheet.

[TRS]

So the 6520 could be controlling vdd, vdimm or vagp?

Yes, pin #6 to #4 with a 10K is the mod

I thought it was pin 6 to vr to ground, is pin 4 ground?

I have had no luck trying to identify the 4410a ic. The triangle is upright and comes before 23cp on the second line. The only ic i have found with the number 4410 is this (http://www.vishay.com/product?docid=71726&query=4410) i thought it might be a vishay product because there symbol is a triangle albeit upside-down.

Yes pin #4 is a GND.

There are several companies that use a triangle is the problem. Another one is "Analog Devices".

Here is a site that shows pretty much all the logos that you will find on an IC. See if you can find it and identify the compnay 100%.

Company Logos (Hhttp://www.dialelec.com/semiconductorlogos.html)

I can't find the same symbol on that list of company logos, i don't think im going to be able to identify that chip.

Im going to do the vcore mod and the 6520 mod. The only soldering iron i have is a portosol superpro gas soldering iron would that be ok or should i just stick to smd grabbers? i can solder but have never soldered such small components before.

[Hell-Fire]

I would use the grabbers then.

I dont know how much heat your iron produces....so I would not apply it to such delicate components.

The typical iron used for this sorta thing is around 15-30w.

You can adjust the heat output by turning the gas dial at the bottom, you can get a wide range of tempretures and pretty much keep it at a constant tempreture. I have actually been practising on an old socket 7 mobo and its been going quite well the only problem is the exhaust port which is quite near the tip of the iron can give out hot gases of up to 580c so i have to turn it off before soldering or make sure the port is not facing the mobo. It looks like im gonna have to use it anyway, i can't find smd grabbers anywhere for a resonable price, besides they look a bit big and prone to accidents.

Thanks for your help Hell-Fire i will post the results when im done, which maybe a while since i currently have no multimeter.

Hi all. Sorry to bring this thread up again.

Wich of all those is the Vdimm mod? My friend and haven't been able to decifer this, and he needs the mod badly.

Could you guys tell me wich of all those is the vdimm mod?

Thanks a lot!
