Thinking about CheapAz picked up an Asus GT 1030 FH, although thinking the components on the front are smaller than than my eyes and fingers can handle so posting for Mac to have a look. Sorry about the glare, snapped a few until I got the glare in mostly underpopulated areas. Can take close up pics if worth while. Attachments:

boy that thing is tiny LOL I thought about picking one up also but gotta send in my main rig stuff so that blows that idea LOL

Okay Brad looks good they dont have the full size Asus cards here only the low profile ones. Will be buying a Galax full size one on Friday. Here are the controllers for both GPU and Mem and readout points I need close ups of those 2 areas to work out voltmods have to know what is on those 2 chips. Tip turn the flash off on the camera.   |

Thanks, I'll do some probing and see what I come up with, have the measure points on the back to compare with. Will have some closeups soon put the cooler back on. The two controllers you pointed out way beyond my age.

Dont worry Brad you dont have to solder to the controller itself just a nearby resistor. |

Used the original photo little fuzzy, if you need them clearer can snap a pic through a magnifier. Attachments:

I need the numbers off the 2 controller chips.

GPU uP1666Q, PGA68Y
MEM uP1540P, PGA6BG
That stuff is small had to get out a 10x loupe

Ok Brad GPU pin 11 is the feedback for the uP1666 I have marked where pin 11 is on the card the opposite corner is pin 1 where the dot is on the chip count anti clockwise 5 pins a side its the first pin on the side where I have put the dot. If you can see where the trace goes it should go to a resistor if you cant see where the trace goes use your multi meter on ohms and find the resistor that is a dead short to that pin and measure the resistance to ground multiply it by 20 and select the next higher value trimmer for it. I havent found a datasheet for the mem as yet I will look again later.  |

Went looking for the MEM controller also, found it for sale but no data sheet. Sorta like the last time I did something like this had no problem with the GPU but MEM never did work. Got on the pin and a reading of .585 have a pad and a resistor, pad largest point. Odd to me last time I did this as I remember was probing in the 20K range which works for everything but the GPU on this card had to drop to the setting below 200 which is a symbol on my DMM and have no idea what the reading means.  |

Can you post a pic of the meter and what you mean?

That's to measure Diodes, you can also sometimes use it to measure voltage regulators. If you're using it, you are verifying if the Diode is still intact overall. It won't help you with what you want right now unfortunately.
Your meter like most only have a range of 200+ Ohms, you'd need a deliberate Resistor Meter to get a better reading in a lower range.

Need an auto range DMM.  |

Ales, that meter has a 0.01 Ohm Resolution on the 200 Ohm setting with a 1.2% accuracy based on its manual. To double check that range to make sure it's still OK, measure a known resistor to make sure nothing has gotten wonky with it. If you measure what you expect (within 5% based on most standard resistors) then I'd double check the measurement point on the card. BTW, I found the manual for that DMM, it's located here; byramlabs.com/store/pdf/sperry/dm-4100a.pdfVin |

My bad at 20K getting 1.00 reading. Meter has a 1 in the display on any setting before use brain didn't register the .00
Thanks for the info & link!!

The 20k range is what you should be using if you get no reading there go up to the 200k range

20K was I thought, so 20K VR should do?

Ok so 1k on the basic circuit feedback doesnt use a resistive divider it just has a resistor between the output and the Feedback pin. I would go with a 50k trimmer Here is the basic circuit below.  |

Sounds good, going for the pad biggest point, resistor is to small for me. Be a day or two before I report back.

I got my Galax GT1030 the other day checked if it ran and then put a waterblock straight on it. I wasnt happy with the way it overclocked was only getting 150 mhz over the standard speed so thought about voltmods. It had an unknown controller for the GPU with just a couple of letters on it and I thought WTF and everything went radical from there. Its certainly clocking a lot better now I havent given the memory any sort of voltage as yet and that is only a couple of runs @ 1.28 volt. More testing tomorrow.    |

Not mad Vin there is a Galax HOF 1080Ti up for grabs in the cheapaschips comp I am going to give it a real go. |

Like the block on the GPU, the Koolance universal block I've got has one of the most complicated mounting systems, its a pain.

The Bot has got it wrong once again Superposition 1080p Extreme needs 3Gb of Vram to run these cards only have 2Gb they will have to change it to Moderate.

See subs for both 1080 & 8k on 2GB cards, pagefile size to small?

Nope think its got something to do with DX12 after Michael said there was subs on the board I went and had a look and they were all done with W10.
So I installed it and sure enough when you select extreme it says not enough Mem but run anyway to which it didnt with W7.
Quite happy with my score too 600 odd was the highest and I got 800 on my first run Epower FTW

Tip Brad use the card that clocks the mem higher makes a big difference.
I wouldnt worry about voltmods for the mem too much my Galax card was giving the mem 1.49v standard after I put the epower on which defaults to 1.5v mem I started raising the voltage for mem only to find it wasnt helping at 1.8v it was crashing the bench.
I looked at jpmboy's rig shot and was surprised he was running 1.41v mem he has got meters glued on and lowered the epower to 1.4v and the mem clock went through the roof.
They all seem to have the same Micron mem chips too.
