So I have this HIS 5870 with a up6213 controller, could you help me in putting a pot for variable voltage?

What would I need for display too like you do with your mods.
Check out mllrs epic guide right HERE

Correct volt display on amazon HERE

Ordered the displays, now to see if I can figure it out myself xD

Mllr's guide is really easy to follow, you should have no problem doing the vmods.

The displays are easy aswell. The red wire goes to +12v, the black wire is ground. For both of those I just go right to the pcie connector. The white wire is the measured voltage. For vmem I usually go to a small smd cap on back of pcb behind mem IC. For vgpu I usually go to standard electrolytic cap near the chokes. Remember that caps have polarity, one side will be vgpu or vmem and the other is ground.

There are several knowledgeable vmod gurus that will be following this thread, so you will get plenty of help if needed. I am sure there will be tons of card/controller specific vmod guides posted in this thread once everyone gets going

Following the guide I get this, does it look right? Just need to understand I measure from the pin up to where. It isn't clear in the guide. Do I measure to resistance to ground or the resistance of the first resistor?

Sizing to pot, the first resistor is like 0.1 ohms and that doesn't seem to make sense for sizing it. That's why I'm a bit lost, but I think apart from sizing the pot, it's ok.

Hope this can help someone else!

Hopefully everyone enjoys the comp and has lots of fun murdering modding their cards!

So if you follow Mllr's modding guide you need to check pin 17 (FB = feedback), multiply it by 20-25 to get the potentiometer (pot) value you need (I would say round down to nearest pot value as these cards eat volts), set the pot to max and solder it between any ground pad and the FB pin (not the actual pin, but any point with the same resistance on the same trace).

You might also need pin 21 (IMAX = OCP limit setting) if you run into OCP issues; in this case you probably should solder a resistor/pot (using the same method as above to find a solder point), of the same resistance as the measured value, to ground to increase the OCP limit.

I would always recommend adding disable/enable switches to your mods as it makes it a lot easier to debug any issues you are having.

When we're taking about measuring resistances it will always be between the point (pin) and ground. (Some OCP/loadline mods are different).

It might be easier to find alternative ground points other than the PCIE power connectors if you have a weak soldering iron.

Spoiler!


uP6213 datasheet link in case anyone wants more information:

Try to measure resistance to ground directly from pin 17 and make note of that value. Then you can check the resistors to find the matching value of pin 17. Most likely it is just the other side of the resistor you circled.

I'll just do the ocp mod too.

Thanks everyone. Is the point for display ok? It's on the + side of the output cap.

It looks fine, but you can check the resistance of both against ground to see which is the output. It might be a very small value, but greater than the ground side.

Edit: Don't forget about the vmem mod as well.

I took like 4 years off, still kept my dewars and most of my pots. Started back up for the team cup and it was fun again.
