RIP BATTLE: Modded RTX 3090 Overclock & Optimus Water Blocks (#RIPPAUL, #RIPJAY)

Rating: 4.0; Vote: 1
We're preparing to RIPJAY, but first, we need to get past Paul. We've leapt far up the Port Royal hall of fame with just water, not even chilled, and some hardmods for our EVGA 3090 FTW3 cards. As a reminder, our objective in this overclocking battle series is always to try and advance ourselves and learn. In this episode of our RIPJAY (JayzTwoCents) and RIPPAUL (Paul's Hardware) challenge, we're trying to learn more about hard modding GPUs, starting with shunt modding an EVGA RTX 3090 FTW3 (specifically, learning more about soldering on these boards). We may venture into more hard mods following that. We're using Optimus Cooling water blocks for the cooling, and as discussed in the video, they're some of the best blocks we've ever tested. The blocks are made in Chicago and these are early prototypes, so we didn't get any instructions or pre-cut thermal pads for ours, but that's not a problem for us. The final version will include both of those things, however.

I m an electronic technician with experience and soldering is one of my best skills. I worked for various companies which both produce apparatus and repair it.
Your soldering isn t really bad (I recall Jayz and immediately get sick). I have one tip - it would be easier if u used two irons to heat both side of the resistor. Hot-air might also be helpful, but I would suggest two irons. It would help more than the board heater u use.
Also - the flux. Basically it helps because it cleans the soldering surface from any dirt and more importantly - oxides, that leads and solder are sensitive to. That s why they get so shiny thanks to flux.

Flux removes and prevents the formation of oxides. The oxides have a higher melting point then solder; they can also be less thermally conductive. Flux gives you clean surfaces for the solder to chemically bond to and pool evenly on. Most solders can't bond to and wet bare copper with a copper oxide layer, same with aluminum; flux will dissolve that oxide layer. Even old solder will form an oxide layer when it goes from shiny new joint to dull old joint.

G'day Steve & Andrew,
Those GPU Blocks are Monsters, it will be Awesome to see what they can do with Ice Water Temps,
Just wondering if you will be forcing Air-con over the GPUs to cool the Memory like Paul & Jay did or just Ambient full room Air-con, the Direct Air-con especially on the backplates may shorten the times between runs, I love the Live Streams but 2Hrs between PortRoyal runs will take forever

its like making videos about unicorns... cool you have a unicorn, but nobody else does, can't even buy one if we wanted, actually cant even buy the slower worse unicorn, does any of this exist in real life? maybe we'll be able to buy one right before they release the 4090... who releases a product in high demand without actually making any products, what a shit show... thx for the vid!

I feel like unlocked vBIOSes should be banned from competitive XOC unless publicly available - otherwise it's unfair advantage vs those who don't have access and have to go the hard way. It's like if someone working for nVidia came out with new unreleased RTX 3099 and crushed all the records on stock clocks, just because of more powerful hardware that others can't get.
reply

Flux is used to:
-lower the melting point of the solder
-decrease the surface tension of the molten metal
-remove and prevent oxidation layer on top of the molten metal that prevents it from wetting the copper or solder joints.
-produce smoke while you solder that targets your eyes.
-spread and smooth the temperature on the board.

Hey Steve. I noticed your Fluke also has a diode mode. When checking resistance of items that have semiconductors in the signal path, using the diode mode will have make sure you don't damage any of the semiconductors. Although, i'm guessing you know this already, and were just avoiding the annoying noise it makes while checking the signal path.

I was recently baptized into soldering with SMD. Simple project, a 4x6 LED panel that has 56 LED's, each with its own resistor. (BigClive's Gallium board).
Even though the resistors are the larger 1206 SMD it's still tricky! I'd send you one of my spare boards to practice on if you had the time to practice on it. :)

chicago puttin it down. ive lived here my whole life and never knew about Optimus machining. apparently Optimus's founding company machined parts for the Lunar Roving Vehicle (LVR) electric motor drive train. Interesting. Thanks for the info, i will be supporting them when i move to an open loop. SUPPORT LOCAL!

Nice vid, well done.... My guess for that glob in the water is some fungal mycelia.... I work in a lab and see that when solutions arent sterile and stand for a while. Add some fungicide before dissasembling unless you want that crap growing in all your wet tubes and blocks during storage
