  • WATER BLOCKS AVALIABLE FOR THESE GEN3 PCB am a class 2 BGA certified technician who has been repairing video cards since 2021
    These 48gb 4090 variants spawned in china due to US export controls of Nvidia enterprise hardware to the SE asia region.
    China does have 4090's but they get a "special" variant which is 10-15% less powerful (AD102-250 D). The 48gb 4090's you get from china are the lower power D variant typically. Here in the USA we are able to source the full power 4090 cores and do the upgrades in the USA. So these cards you get are fully made in the USA
    I use my skills in the USA to source 4090's from second hand markets which have full power AD102-300/1 core variants and the latest GEN 3 48gb 4090 PCB's (with better power/cooling configuration)
    Im based out of Michigan USA and offer support, warranty, and repairs. Due to the fact that the 4090's product cycle being discontinued, im working on used/short supply of 4090's for this modification. As such, I can only offer a 90 day warranty, with 1 year option as an add on.

    Video of the new generation 3 PCB (jan 2026) is available: cards work out of the box, plug and play, with nvidia drivers on linux and windows with no configuration needed.
    Memory performance is not effected from the stock 4090 You can expect a stable 900 GB/s (+/- 6%) memory bandwidth.
    TDP: 450WConnector: 12VHPWRPCIE 4.0 x16
    SIZE: 10.5 x 4.5'' (2 slot pcie spacing)
    Displays:3x DP 1.41x HDMI 2.1
    Size: Exact same size as an A100/A6000 gpu, meant to be stacked for high density configurations 2-8 GPU's per system. Excellent for server chassis.
    THESE ARE LOUD! They are blower configuration cards, while they do not whine like 1u servers, they WHIRRR pretty loud and noticeably if you are in the same room and run any kind of load on them. This is a server cabinet/other room type of card, not for process:During every step of the processhigh quality Stirri soldering flux is used specific to this type of BGA rework. Afterwards, asonic cleaning process with an american made Crest ultra sonic cleaner is used to give these cards a fab level finish to ensure no surface resistive dielectrics are left under the BGA to cause signaling issues (the ram bus runs at 10GHz!)
    Testing and validation:Each card is run through a thorough validation procedure which includes pytorch and various LLM/diffusion workloads, GPU Burn, Furmark and vulkam memtest. Each card is tested and a validation receipt is printed and included with each card post-sale.
    Shipping:Cards comes with port protectors installed, and are sealed in a dri-shield Mylar ESD bag, and packaged in a ESD safe foam mailer. The cards are double boxed with bubblewrap in between each box.
