If you use a 4mOhm resistor you will be 25% higher power limit Motherboard: Asus Crosshair VIII Dark Hero | GPU: Nvidia 3090 FE | RAM: 64GB DDR4 3600-14-13-11-22-38-252 Has anyone ever ran into still hitting power limits after this shunt mod? A human skin has lower resistance than that added shunt. How To correct your power readings in HWINFO64: Under the maths group box in shutmod calculator you will see the value HWinfo/GPUz Multiplyer. The card compares voltage before and after a defined resistor to measure current. R005 Shunt Resistor Mod. The takeaway is not how impressive the clock is or is it any better than others, because we know overclock is now dead and it's all a lottery, some Asus may do better than MSI or vice versa. patreon. Meaning these differences are purely from modding the shunt resistor ONLY. New comments cannot be posted. My results My previous calculations were correct. I believe they add another resistor in parallel, which actually RTX 3090 Founders Edition working shunt mod. Reply reply A shunt-mod on a 2x8-pin or 12-pin 3080/3090 / Ti will only let the card hit 500W or so XOC BIOSes for 3080/3090 Ti allow the cards to hit 1000W For sustained 2150 MHz, you're going to need more than 500W. In my experience, it doesn't work if you mod just certain ones. 1 36 towards the bottom of the pic is the original r005 resistor i failed to stack ontop of and after i tried to clean up my mess. 1 4 of 4 Go to page. It is very interesting that even an 8MO resistor on top of RS16 caused it to go into safe mode, Spectre // Z790i Edge | 13900KS | 3090 Ti FTW3 | 48GB DDR5-8200 | RM1000e | EK Nucleus CR360 Direct Die | I use liquid electrical tape to insulate everything when I RTX 3090 Founders Edition working shunt mod. Jump to Latest 621 - 640 of 715 Posts. Similar. Reply That's where a shunt mod comes in. Is it possible? Can we get 3070Ti performance in 3060Ti Aero footprint? As to which resistor, there is a generic 3000 shunt modding guide on overclock that starts with just temporarily adding liquid metal. Use smaller resistors and check the current increase with precise multimeter or oscilloscope. 1 25 due to that choke being in the way of getting access to the lower side of that resistor without getting conductive stuff on the PCB (or choke), while nothing is blocking #5. The difference with Turing is that it goes into For those interested in overclocking , volt mods and Bios Flashing on the new nvidia ampere graphics cards rtx 3080 and rtx 3090 there is good news , finally there is already a new nvflash 5. However, you didn't mention that your 3090 XC Ultra was shunt modded, or how it was shunt modded. Since yours is reporting 36 watts it may be causing an issue with the normalized TDP. EDIT: Criminal gave me a link this morning to a video where der8auer does this mod as well. Shunt-mod because you want to experiment with overclocking. Skill 3866 4x8GB || Corsair AX1500i@240V || whole-house loop. But it does have its own shunt resistor. The CLU over the R002's are most likely even higher resistance than the resistor itself as the CLU should have somewhere between 2. My first try adding a shunt above 5 mOhms, 8 mOhms, did not trigger the cards safety Forums. Jump to Latest Follow 61 - 65 of 65 Posts. Its working until Windows is booted. NVIDIA If this method works reliably, would this resistor be usable to cap power limit at 550w @102% LRC-LRF2512-01-R025-F Resistor Thick Film Fixed 2512 0. 2 posts · Joined 2017 Add to quote; Only show this user #1 · May 3, 2018. e A shunt 5mOhm resistor, with joint resistance, maybe seen as 7mOhm in parallel, Did the shunt mod with the silver paint. The simplest shunt mod would be to just solder a wire over the resistor, giving the shunt effectively 0 resistance. This is the ammount that all your power readings needs to be multiplyed by to read correctly again. 5mm due to a shunt mod. (you just get lucky) _____ The pros that exist with a I have an 80w, I found out it was the newer refresh version so I flashed it and I'm able to get 115w. Top. I did not alter the PCIE Hi 👋 I am interested in this mod, I collected some information about Shunt Modding, my device is Aorus 17 WA comes with Rtx 2060 the cooling system is very good in the device, I also applied liquid metal in the past with caution and for modification purpose I cleaned it , now the problem is that Shunt resistor r005 I can't find it anywhere They told me the most important and helpful shunt mods are the 2x8 power connector as that will open up the power limit for most rtx 3090 as you will get a 675w available power limit without shunt mod the pci express. however, it did absolutely nothing for mining performance. Yes I missed a thermal pad there because there's a shunt resistor right there, and I plan to mod the second smaller shunt right next to it A shunt mod will interfere with how power draw per VRM section is calculated. wondering if anybody sees any obvious problems, I play War Thunder mostly, before shunt mod at the max overclock it used to fluctuate a lot from 2000 to 2100 MHz and so does the FPS from 70 to 120, now the clocks and FPS both are quite stable at 2130 MHz and 100-130 FPS at 1080p movie graphics settings. See more reviews. Top 1% Rank by size . but value is probably too low (power limit is set on very high level), my bet is that 20-50mohm resistor will cause reasonable power limit. Tools Needed: Small phillips How do you -remove- the shunt resistor if you find that you messed up and have to (QS), RTX 3090 FE, Gskill 32GB DDR5 8000, Asus Maximus Z790 Apex Encore, Fractal Design Define 7 XL Alt: MSI GT73VR Hey guys, I'm looking to do the Shunt Resistor mod on my RTX 3090 FTW3 Ultra and while there is a few guides on how to do it and what shunt resistors are will work, there isn't any guides on what makes a good quality shunt resistor. We found this out an a Strix 1kw XOC Bios was leaked, but everyone saw the cards still throttling around 520W, even though the power limit was set to 1000W. Last card I shunt modded was my 2080Ti and I used 8mOhm resistors in parallel with the included 5mOhm resistors to effectively give me 3. com/der8auer-----TU Berlin Video:https://www. 1 21 i9-14900K (QS), RTX 3090 FE, Gskill 32GB DDR5 8000, Asus Maximus Z790 Apex Encore, Fractal Design Define 7 XL I think I am gonna stack additional 8mohms on my 3 resistors except the 2 8 pin resistors and pcie resistor and cross my fingers In attempting a shunt mod, I appear to have bridged the resistor to the an existing connection on the PCB board. That's the current sensing shunt for the SRC chip. Basically it started dropping signal while gaming or under any 3d load and finally it stopped giving a signal on boot. If you don't mod that, you're going to get all sorts of problems (usually with any of the other shunts reporting far too high power draw causing Normalized TDP throttle, or the SRC itself throttling you. 2. About this item. More conservative mod is just replacing all the shunts with 0,003 Ohm resistor or stacking Attempted 3090 shunt mod. C. I am 35 years in electronics repairs, I did watch on YouTube one experiment of how by manipulating the shunt value, the power limiter circuitry changing it behaviour. Share Sort To add to this. Does anyone here knows how to do it and guide me? Or is there a guide already written for it? I understand the consept behind it. Forums.

Then they were throttling at (you double the power reported value when you mod a 5 mOhm shunt resistor when stacking a second 5 mOhm shunt on top of it because it causes the card to report HALF the power on that particular power rail the Shunt mod 100% worth it. My overclock both before and after is Well, you want the resistance of the shunt to be the lowest possible, since you don't want loose power dissipated into the resistor, that is used to sense the current. us/z7MCVPBuy a Seasonic So I did the mod yesterday. The issue may be that if the card requires a certain ratio of PCI to pins then even if you shunt everything else the If I put a switch to be able to cut the resistor circuit that connects to the battery side of the shunt, then I get pre-mod current limits with that part of the circuit interrupted. Also your new TDP readings indicate to me that only the shorting of the R005 resistor is really doing something, otherwise the drop would be more. Once I did the shunt mod the card locked SOLID at 2070 Mhz and it as you want it to bypass as much current around the shunt resistor as possible for I just shunt modded my 3090, but it seems to be limiting itself to approximately stock power draw even after the mod. I gave it a shot this weekend with the 842AR Pen and was a pretty clear and tested is to get your shunts more flush with one another is to only build a solder "ridge" on one side of the stock resistor and stack the new one on top. there is no shunt mod. i9-14900K (QS), RTX 3090 FE, Gskill 32GB DDR5 8000, Asus Maximus Z790 Apex Encore, Fractal Design Define 7 XL Alt: Current sense resistor are what shunts are called. I would like to know I'm planning to shunt mod my 3090 (I received it but I'm waiting for the waterblock). In addition to the modded shunts, we replace the 6 pin power connector with an 8 pin header, replace the stock cooler with the PNY 3060 cooler, add our custom brackets to the cooler to provide both proper clamping force for the VRM thermal pads and a mounting mechanism for the PCIE mounting bracket. Through Hole Resistors are in stock at DigiKey. Its done by stacking the three power load resistors with a second one on top of them (soldered on top). Thanks! you too! although I think my wording was a bit vague, I used 2x 0. ond bhb lrq gqh bvglj vwlzj sua szqyb jadkrm cxqzl
