Actually, the pinout alone would do. I wouldn't even need any more, but upi doesn't seem to want to make the data public.

Simply jaw dropping. The attention to detail and the precision with which you built that system just leaves me in awe! Great work and my honest respect for those skills that you displayed here. :up:

Hi guys,

it's been some time now, since I last posted here.

My question today is:
Does anyone have access to the datasheet of the uP1501 (upi-semi) vcore controller?

I have a MSI H61I-E35...

@hank123:
Real easy solution:

Stop posting here and we can't hold you back anymore on those awesome voltmod skills of yours. ;-)

We don't need posts like that around here.

The really interesting question is:
Is the PCI slot on your mainboard able to deliever the power that this card solely draws through the slot?
The card you have there is a low power model without...

From the looks of it it's quite possible that the identical looking section also uses identical parts. BUT, that is just a guess, as I don't have the exact schematics or a identical card to measure....

0.8V sounds like the reference voltage.

So, my guess is that the regulators equation for the output voltage (often the same on these regulators) is:

Vout = 0.8V x (1 + R1/R2)

That means that...

OK, that should be fine.

Good to hear. Just one last question:
The power usage now increases slower in comparison to what? The original card, or with the two broken caps? :confused:

It does somehow matter because 0805 is way easier to solder than 0402. But in general it really doesn't matter much as long as the capacitance value and the other electrical chracteristics fit the...

The amperage limit is per cable and is an estimate, because we don't know the exact cable diameter. Per cable in this context means, that one molex cable strand consisting of 4 single cables (12V, 2x...

I'm pretty sure now that it's 0805, but it absolutely won't hurt much to buy both sizes.
Looking at the caps on the back of the RAM chips, right to the left of the damaged caps, the smallest should...

Looks like 0805 would be a better idea afterall. At least if my vision is still OK at this hour of the day.

BTW, I'm not 100% sure that 0603 is the right size. The size should be double checked before ordering anything. I just guessed it judging by the not so clear pic in the first post. I'm quite positive...

No problem, just read my edit. You were right, I really was strained and therefore quite rude today without even noticing it. Really unnecessary stuff, but hey, :banana::banana::banana::banana:...

Then show me the gazzillion of broken GTX470 cards if it's that easy to get ahold of one instead of ordering two (or maybe a bit more depending on the source) ceramic capacitors.

Instead you...

@PiLsY:
If you post nonsense, then don't get pissy on me my friend.
And again your new posting doesn't help one bit and states things that are plain wrong, AGAIN.


I see. So I wrote that anyone...

If you'd like to see a resistor go up in flames you could still try what you first intended to do. :D

What you want is a multiturn trimmer potentiometer and those are anything but hard to get. And...

10 seconds + google = http://www.techpowerup.com/articles//overclocking/voltmods/130/3

The one on the bottom is the mod you need. The keyword is "variable". ;)

Sorry, bu that's just plain wrong. Or do you go out and buy a new (or used) car every time you have a flat tire? Sorry for the exaggeration, but I think you know what I mean.
The thing is only that...

Most likely 0603 ceramic SMD capacitors. Value, don't know and without details there's no sense in stating a number. My guess would be that those are for power and not for signal filtering. So maybe...

Bad idea, regardless of the resistor rating. That mod looks like it just shorts the 3.3V rail to Vdimm. That means your resistor would be in the direct current path.

And why the hell would you...

Good luck. Hope it all works out the way you want it.

Depends on where you plan to go VGPU wise. If an increase in VGPU of about max. 20% is fine with you, then the 20k trimmer should be OK. If you want higher voltages, then you should maybe consider...

I intentionally left the quoted question out when trying a last time to give some advice.

But now all that comes to mind about



is: Prove me wrong! And I honestly mean it.
It must either...
