Hi guys,

can you help me with that pinout: http://www.ti.com/lit/ds/symlink/msp430f5510.pdf

 

It's the vMem Controller on my GTX680 SOC (M430F5510). Not really sure which pin is FB. Pin 17 maybe?

Just running the card on 1476MHz GPU@H20 in 3DM11 and higher Memory clocks would be more than welcome

 

Thanks in advance

[xoqolatl]

That's a 16-bit RISC MCU, not a buck controller driver

Look for something with less legs or post a picture of the PCB. I think memory power supply is located to the front of that card, between IO and GPU.

You were right, forgot to look at the back side... There is a CHiL CHL8212 in the front: http://www.digchip.com/datasheets/parts/datasheet/232/CHL8212-pdf.php

 

Pin 3 (VSEN) right? It's the one in Figure 3.

[xoqolatl]

Looks like it, but you do it at your own risk

Could someone give me a quick hand on what I would need to do for OVP and OCP mods for an APW7098

http://www.alldatasheet.com/datasheet-pdf/pdf/316993/ANPEC/APW7098.html

[CL3P20]

best way for quick fix of APW is with VID mod.. which will increase OCP and OVP together

And how would I do so as I have no idea about vid mods and it doesn't show anything about vid in the data sheet. Thanks in advance

[newlife]

Sorry for double post but I have included the tested and proven mods (by me) for a reference sapphire hd 7750

 

I've include link to my imgur album with full res as hwbot has a size limit http://imgur.com/a/VfN6E

 

Ps. I really need to know how to do a OCP/OVP mod for this card

Edited September 8, 2014 by newlife

[CL3P20]

after looking back through DS, seem there is no VID for this application

 

*OVP will always be +125% of set voltage using 'FB' .. at higher volts/clocks you may trip OVP under load.

*OCP can be adjusted by increasing resistance for CSN1 and CSN2 - which monitor power through inductors/phases

[newlife]

Thanks for that you confirmed what I was thinking about ocp and what would I do to increase the resistance as wouldn't adding a trimpot decrease it?

 

Edit: The only thing I can think of is replacing the resistor with a trimpot and csn1/2 both read 2kohm

Edited September 8, 2014 by newlife

[CL3P20]

yes, you must replace the resistor .. either with another of higher value or with VR

[newlife]

Thanks once again

 

Mind my ignorance but would it possible to solder a VR in series between the resistor and CSN and cut the trace/IC leg? I have a dead card which I'm probably going to test it on and due to the resistors size I don't think I would be able to remove them

Halp guys!

 

Boght this gem few days ago - ABIT AX78 AM2+. Being a 3+1 vrm it struggles real hard with Phenom quads, I get OCP shutdown over 3 ghz 1,5 vcore. I refuse to find another mobo - this will be OCP modded even if it so will end up frying both mobo and cpu!

 

Vrm IC is ISL 6323 http://www.intersil.com/content/dam/Intersil/documents/isl6/isl6323.pdf

[CL3P20]

@ newlife - use some fine surgical tweezers if you can to squeeze the resistor and 'rock' back'n'forth until it pops free. *otherwise.. I would try your idea with trace/cut.. just make sure you can test and repair if necessary.

 

@ Calethea -

 

*RSET & ISEN1,2,3,4 will be for OCP.. trace them to resistors for mod, increasing resistance should move OCP range higher

*VSEN - OVP .. may not be necessary, trigger is ~1.73v; trace to resistor for mod, increasing resistance should move OVP range higher

*FS -> VCC - Frequency switching may help.. to disable set droop, make sure FS pin is tied to VCC with resistor (and not ground).

[Calathea]

Thanks CL3P20. Not really and easy mod then. What would happen if I only replace RSET with higher r?

 

edit: in fact I think there is no resistor between ISEN 1,2,3,4+ and VCC.

Edited September 12, 2014 by Calathea

[CL3P20]

it may work to lower OCP.. see where stock value is at according to the below

 

*from DS - " Connect this pin to the VCC pin through a resistor (RSET) to set the effective value of

the internal RISEN current sense resistors. The values of the RSET resistor should be no

less than 20kΩ and no more than 80kΩ"

[Calathea]

Yep, if it's below say 60k I will switch it to a 100k VR instead. Thanks for the help.

 

Edit: Just to update, the mod works! I can run the x4 9850BE 3400 MHz @ 1.43 vcore wprime 1024m, no ocp what so ever. Power draw at wall is 300 W and vrm reach 100 °C though... I think this is not advisable!

Dunno where to post.

Any bios mod or program to bypass the limit of 1.350v of afterburner on a Msi 7970 Lightning (1070/1400). ?

 

Or any other way besides hardmod to increase voltage in this card ?

[newlife]

Use a memory editor like artmoney to increase the limit in ab by searching for the max volts in a memory editor which in this case is 1350 and the memory address will start with something like 44 or 45. You need to have AB running and not minimized for it to work

This works for HD7870 too and probably many other vga too. Cool way of softmod!
