So I went and bought a Asus 512 DDR3 Silent, figuring the mod would be the same as your 1GB posted earlier in the thread but it appears different. I think that the circuitry is labelled the same but your PU1 and PU2 area are on the back of the card. I attached a couple of pics but they are crappy ones from a cell phone camera until I can get my hands on a higher res one. The 512 version only has PU2 on the back of the card. PU1 is on the front of the card. The interesting thing is that on those areas I see two ICs labelled APW7165A, I've attached the datasheet for them. Would I simply put a VR on the Pin 6 to ground (or am I wrongly assuming what a buck controller does?) Also reading the datasheet am I going to have to worry about OVP?

Just looks like a slightly different layout, duno why. Yes, the mod is from pin6 to ground, size is based on what you read form pin6 though. I duno what you assume a buck controller does, but what is does do is converts the high voltage down to what the chip needs (bucks the voltage down, as oppsed to a boost converter)

From the datasheet:
Quote:
The over-voltage protection monitors the FB voltage to prevent the output from over-voltage condition. When the output voltage rises above 120% of the nominal output voltage, the APW7165 turns off the high-side MOSFET and turns on the low-side MOSFET until the output voltage falls below the falling OVP threshold, regulating the output voltage around the OVP threshold.
Since we are reducing the voltage at FB using the vr mod (which makes the chip think the output is too low and increases it to return FB to normal), the only time you will see OVP is if you get a spike in the output. If that happens, then you are really need to be adding more phases wink.gif

OCP might be an issue, but I haven't encountered it yet.

Okay, I see this card is more like your 1GB version and your 512 version is different. Mixed up your mod pictures. I'm reading almost identical ohms on this card (946 on the mem and 534 on the core). So 10K on the Mem and 20K on the Core should work. Other random question though. Is there a reason that you use Pin3 for ground and not just run a wire to any suitable place for ground, even the slot bracket that is easier to attach a wire to. For me, every solder on an IC is risky so why take the chance unless there is a good reason for it? Thanks again, will post some high res once the mod is done or the card is dead. biggrin.gif

No reason, just felt like doing it like that rolleyes.gif. I do like soldering to those 8 pin chips, they're good people.

This. After soldering the tiny little resistors & pads needed for some mods, those ICs have some pretty roomy soldering points. I'll probably ground near the back of the card & run a wire to the IC for FB though, I like the VRs at the back for easy access. Learned the hard way that long hair can be bad leaning over the mobo when fans are running so I don't want them near the bracket behind a cooler where I have to look down at them.

wow thanks guys for the posts.. im glad im not the first one asking questions ... i need to read up and take a look at the cards. I have the msi omg this has to be a new revision as the chips are sooo small. And all components on top side. Ill post more when i have time. I have other cards and parts comming.. my best card got cancled after 5 days. moving forward. :>
