Ladies and gentlemen I bring you the GTX 590 AHOC edition

It's huge 
It's impractical
It might not even work
But now it's finally compelete and ready to occupy the top 1% of GTX 590s

The E-power is fully attached I will be mounting the coolers and doing the final chekups tomorrow

Here are some pictures of the monster I've created.

Well it won't fit into any case I know of the the power plane leading to one of the cores seems to be shorted because I'm reading 0.6 ohms to GND. So worst case I'll have to rewire that plane. I did manage to attach pin 17 properly so if pin 16 really was GND this card will still work.
Good news there is most likely not a short on my GTX 590 because I just checked VCC to GND of my  HD 5850 and got 1.8 ohm. So assuming that the GF 110 core has around 1 to 1.1 ohms of resistance my GTX 590 where the VCC is hooked up to both cores should read 1.1/2 so 0.55ohm which would be in line with the reading I'm getting right now. So now I just have to fix one resistor which went missing and fix 2 VCC wires that I pulled when looking for shorts and the card will be fully operational tomorrow.

Sorry about the photo quality but I can't change that without getting a new phone or a camera.
Also I recently revised the support me page so please go check it out.


As always remember to checkout SiliconLottery if you are considering buying an i7 and overclocking it. They sell binned CPUs so you won't have to worry about getting a crap chip.

Bad news EDIT: Now kinda good

So I've been working on attaching the E-power to the GTX 590 and due to my lack of skill and equipment it looks like the card won't make it.
1. The VCC to GND reads 0.8ohms. IDK if this is wrong or right because that's what it read even before I started soldering and GND to GND is 0.5 ohms so maybe my multimeter just really sucks or the cores of the 590s are really low resistance or I have a short.

2. I managed to spill solder on the PCI-e gold fingers and in the process of trying to clean them I managed to completely destroy 2 of them. Hopefully they were GND pins. If they weren't this card is most likely not going to work.

The fact is I'm not really equipped to do these kinds of mods I have a 50W regulated and 150W unregulated soldering iron. The problem is that the 150W is intended for connecting metals not PCB work however low wattage irons like my 50W do not have a chance when trying to work on circuit boards that contain as much copper as GPU or motherboard. Also the PCB of the GTX 590 is a cramped mess with tiny voltage plains and no where near enough GND plain on the core side to work with. Hopefully the GTX 590 will make but right now I think the card is dead so if there is no weekend post it's because I'm digging it a grave.

Go checkout silicon lottery their my sponsor. They bin i7s so if you want an i7 with which will surely run a certain clock go check them out.

EDIT: So I just checked the pin against Wikipedia and it should be a GND pin. If it is then I'm fine. I will still finish of the E-power attachment however I will need to find new ways to mount the cooler since the wires are everywhere and the card still isn't fully grounded(18/30 wires).

Hide your motherboards and GPUs buildzoid got an E-power

LADIES AND GENTLEMEN I BRING YOU
POWER!

You have no idea how excited getting an EVGA post box made me today. I've been wanting to buy the E-power for 2 years and waiting to do put this on the GTX 590 for just as long. Now you may be thinking. Why did he only buy 1 E-power to power a GTX 590. The E-power is only rated at 400A on the EVGA spec sheet. The thing is that EVGA spec sheet is actually very conservative. The low side MOSFETs on this beast are IR 6725s these are absolute power houses rated at a continuous drain current of 170A at 25C. This derates to 60A at 125C however there are 14 of them. 14 60A MOSFETs that's a total of 840 amps at 125C. Now if you actually use the E-power properly you should be running it cooler. So in fact a single E-power can power an overclocked GTX 590 just fine. That is as long as you don't use LN2 because the E-power does come with a 900A OCP which would trip when using LN2 and 1.5V.
The GTX 590 isn't the only thing I plan to use this one of these. I also want to use it on this motherboard to build an MATX 5+Ghz FX 9590 computer. No I don't need to go see a doctor about having OC sickness. Why wouldn't you want to attach a 59 euro VRM to a 60 euro motherboard.

I would like to thank Silicon Lottery for being my sponsor. They sell pre binned i7s so if you want to avoid having to deal with the variance in CPU overclocking capabilities you can just buy a CPU from them.
