Mega Ultimate Voltage (UMV)

Mega Ultimate Voltage (UMV) is the twelfth electric tier in GregTech: New Horizons. Its primary focus is the Eye of Harmony, a multiblock that is extremely expensive both to make and to run, and which is required to progress to the next and final tier, UXV. It is one of the most straightforward tiers in the pack, with very few new technologies outside of its main progression pathway.

By the time the player begins producing UMV components, they should have a DTPF with Eternal coils, providing access to a better SpaceTime recipe, in addition to new materials like Shirabon and UMV Superconductor Base. Shirabon is required to make Quantum Circuits, the only UXV circuit, which are needed to make UMV Field Generators and casings for the Eye of Harmony.

The UMV Component Assembly Line (CoAL) is one of the most useful CoAL tiers, and should be made very early in UMV. It is fairly cheap with an Eternal DTPF for SpaceTime and Hypogen, and provides a discount on the large amount of UMV components needed for Wireless Energy Hatches and the Eye of Harmony. It also covers any skipped lower tier CoALs, and doubles the speed of all lower tier components.

The Eye of Harmony (EoH) is the center of UMV progression. It is a very expensive multiblock that is able to produce almost every dust in the game, largely replacing Space Elevator Miners and Void Miners, as well as all the plasmas used for Exotic Catalyst, but its main use is making the four materials that cannot be produced in any other way: White Dwarf Matter, Black Dwarf Matter, Universium, and Stellar Plasma. Stellar Plasma is produced by all EoH recipes, and is primarily used for the top tier DTPF catalyst, making various UXV materials, and running parallels in the EoH, and is also usable as fuel for the Godforge. White Dwarf Matter is only produced by tier 1-tier 3 recipes, and is mainly used in tier 2-tier 4 casings. Black Dwarf Matter is similar: it is only produced by tier 4-tier 6 recipes, and mainly used in tier 5-tier 7 casings. Universium is produced by tier 7-tier 9 recipes, and is required for tier 8-tier 9 casings, but its main use is UXV components, which demand very large amounts of it.

Climbing the tiers of the Eye of Harmony is necessary to finish UMV. The EoH has three different types of casings: spacetime compression field generators, which determine maximum recipe tier, time dilation field generators, which increase speed, and stabilisation field generators, which increase recipe success chance. Determining the best order to upgrade them is complex, but one example is listed on the Eye of Harmony's wiki page. At base speed, the EoH is incredibly slow, encouraging players to overclock it. However, the EoH has inefficient overclocks compared to most other machines (taking 8x the EU/t for 2x the speed, as compared to 4x for most machines), forcing players who want to overclock the EoH to expand their power production first. Although only a 7/x/x EoH is strictly needed to start UXV, its Universium production is unusably slow for any serious UXV crafts; a 9/9/9 EoH with Astral Arrays for parallels will be needed before UXV components become easily affordable.

Stellar catalyst is the fifth and final tier of DTPF catalyst, made from Stellar Plasma. Unlike the first four tiers, all of which require only plasmas that can be made in a Fusion Reactor Mk3, Stellar catalyst requires two Mk5 recipes (for Lead and Thorium Plasma) and a Plasma Fabricator recipe (for Naquadria Plasma), in addition to the Stellar Plasma. Many low-tier DTPF recipes, such as Neutronium or LuV-UV Superconductor Base, do not have Stellar catalyst variants, meaning Exotic catalyst remains useful even after Stellar catalyst can be produced in bulk. However, some materials, such as Hypogen and UHV+ Superconductor Base, do have improved Stellar variants, and Stellar catalyst is the only catalyst accepted for a few recipes, such as the direct Tesseract to Transcendent Metal recipe.

The Forge of the Gods (Godforge), which was optional in UIV, is required by the end of UMV in order to produce Magmatter, which is needed for all UXV components.

Producing Magmatter requires the END upgrade, the final upgrade in the Godforge's upgrade tree, which needs a minimum of 84 Graviton Shards to reach if all optional upgrades are skipped. 99 Graviton Shards are obtainable before the END upgrade, since the last two steps in the Composition milestone both require it, meaning that only 15 Graviton Shards can go uncollected. This can be done in one of two main ways: by skipping the tier 7 on two of the three available milestones, or by skipping both the tier 6 and tier 7 on one of the three milestones. In both cases, all of the other milestones must be completed up to tier 7. Another option is to avoid making the second ring, leaving Composition at tier 4, and only have one other milestone below tier 7. The following table lists the requirements for each of these skippable milestones.

Catalyst is mainly progressed by using a high Fuel Consumption Factor (especially after the TSE upgrade) over a long time, and using higher tier fuels for the Godforge: Dimensionally Transcendent Residue has very punishing exponential scaling, while Stellar Plasma has less punishing exponential scaling and Magnetohydrodynamically Constrained Star Matter scales linearly, although the latter is not practical until UXV. Charge and Conversion can both be progressed by running as many recipes as possible, with the former benefiting from the TBF upgrade and the latter from anything that increases parallels.

Both of these routes will leave at least one Graviton Shard left over after completing the END upgrade. Combined with the 6 Graviton Shards that can be immediately obtained from placing a Heliofusion Exoticizer in Magmatter mode, it is possible to get the TPTP upgrade even if the player did not originally go down the right path in the upgrade tree's split. This upgrade is necessary for producing Magmatter, since some of the plasmas that the recipe can request are multi-step, and can only be made in the Plasma Fabricator.

In addition to Graviton Shards, many of the upgrades also require items to be inserted to complete them. The most notable costs are the Eternity and Universium needed for the last two upgrades, forcing them to be unlocked only after a tier 7 Eye of Harmony, and the 24 total UMV batteries required for all of the upgrades.

The Eye of Harmony is extremely power-hungry, and will likely consume most of the player's power generation while they progress through its tiers. Without any overclocks its power usage is fairly modest, on the order of 100B EU/t, but it is also extremely slow, and adding even a single overclock increases it to multiple trillion EU/t due to its very inefficient overclocks. In UMV, there are three viable sources of power to run the Eye of Harmony and its supporting infrastructure.

Dyson Swarm Ground Units (Dysons) remain viable in UMV to power the Eye of Harmony and its supporting infrastructure, although unlike Antimatter or power EoHs, they cannot scale through UXV. The Matter Manipulator is very useful for placing large numbers of Dysons and their supporting Quantum Computers, and the Energized Wireless Dynamo Hatch can be used to avoid placing Lapotronic Supercapacitors. Completing UMV comfortably with Dysons typically requires dozens of them, and completing the tier quickly can take hundreds.

See More: Naquadah Fuel Refinery and Large Naquadah Reactor

Naqfuel in UMV should be built with an eye towards using depleted Naq5 or Naq6 in the SSASS, although in UMV power demands can be low enough to still rely only on the Large Naquadah Reactor. UMV also unlocks the final upgrades to Naqfuel, with Tier 4 coils for the Naquadah Fuel Refinery allowing all recipes, including a single-step recipe for Naq4, as well as the ability to make Naq6 using Shirabon and optionally Stellar Plasma. The Energized Wireless Dynamo Hatch can also be used to simplify the logistics of getting power out of Large Naquadah Reactor arrays.

See More: Semi-Stable Antimatter Stabilization Sequencer and Shielded Lagrangian Annihilation Matrix

Antimatter becomes much more powerful in UMV, thanks to the tier unlocking much better additives for the Semi-Stable Antimatter Stabilization Sequencer that allow for each one to produce over 100T EU/t when properly supplied. In early UMV, these additives are Tachyon Rich Temporal Fluid, Spatially Enlarged Fluid, Molten Shirabon, and depleted Naq6, which can produce nearly 60T EU/t per SSASS. Later in the tier, Molten Eternity can be used to more than double this number. The Stabilized Lagrangian Annihilation Matrix can now use UMV Superconductor Base as its matter, which increases the net EU/t produced by as much as 24% and allows it to output directly to the wireless network.

The second viable method of endgame power generation is the power-generating Eye of Harmony. After improving an EoH to 7/7/7 or better, it becomes net-positive on power as long as it does not run any overclocks or parallels. Power-generating EoHs can produce a maximum of 12.87T EU/t when running the T10 Deep Dark recipe with 9/9/9 casings, meaning that reaching the Stargate typically requires at least a hundred of them.

UMV adds many new hatches for working with wireless energy, capable of replacing non-wireless energy for everything except multiblocks that need laser hatches. UXV circuits unlock UIV and UMV Wireless Energy Hatches, meaning that unlike in UIV, it is possible to use wireless for on-tier power. In addition, Shirabon unlocks multi-amp (although not laser) Wireless Energy Hatches, which are helpful for multiblocks like the Hyper-Intensity Laser Engraver or Quantum Computer, that accept multi-amp hatches and either don't accept or don't need laser hatches. The UMV Capacitor can also be used to download up to 10P EU/t to a Lapotronic Supercapacitor, for any multiblocks that need enough energy from laser hatches that the UIV Capacitor is insufficient.

UMV also introduces the only wireless Dynamo Hatch, the Energized Wireless Dynamo Hatch, which can be used on Dyson Swarm Ground Units or Large Naquadah Reactors (although not the Stabilized Lagrangian Annihilation Matrix) and can output up to 65,536 amps of UMV (approximately 8.8T EU/t) directly to the wireless network. Crafting it requires an Eye of Harmony, as the recipe uses Stellar Catalyst.

See More: DTPF#Dimensional Convergence

Dimensional Convergence is a mechanic that can be used to gain perfect overclocks for the DTPF, at the cost of increased catalyst consumption. It is unlocked in UMV, requiring UMV Energy Hatches and Field Generators to make the Transdimensional Alignment Matrix that is used to activate it in a DTPF. Although convergence is never required, it is very useful for avoiding DTPF spam or immense power consumption in the endgame. However, because it requires a full catalyst discount to run, using convergence demands the ability to run a DTPF passively with 100% uptime, including the increased speed and catalyst usage of convergence. An Eye of Harmony running the Deep Dark recipe can help with this, as that recipe produces all 16 plasmas used for Exotic Catalyst.

Building the Eye of Harmony requires robust on-demand crafting infrastructure, especially for its higher tier casings. In order to bring the crafting time for Eye of Harmony parts to a reasonable level, UMV demands players to scale their arrays of standard on-demand machines, such as Industrial Cutting Factories and Fluid Shapers. The Matter Manipulator is highly recommended for doing this. Priority rotation between Crafting Input Proxies can be used to reduce the risk of bottlenecks on these machines.

Advanced Assembly Lines (AALs) are particularly important to scale, because of how slow the recipes for EoH casings are. Before overclocking, tier 1 casings take 4000 seconds, or 66 minutes, to craft, and each tier adds another 4000 seconds to the recipe time, up to 36000 seconds, or 10 hours, for tier 9 casings. Many of the ingredients in their recipes also require the Assembly Line, including very large quantities of high-tier circuits. This demand can be handled either by making dedicated AALs for each of the slow recipes or by scaling universal AALs, but in either case it is necessary to build more AALs and supply them with more power.

Shirabon also unlocks the Cloud Computation Client Hatch and Cloud Computation Server Hatch, which can be used to transfer computation wirelessly between Quantum Computers, Network Switches, and computation-using multiblocks such as the Research Station. Like wireless Assembly Line data, wireless computation is many-to-many, unlike its wired equivalent, which is one-to-one.

UMV unlocks two Space Elevator upgrades, although both require Universium and as such are late in the tier. The first is the Mk5 motor, the highest tier, which unlocks all 24 module slots and is required for the Mk3 Space Assembler module. The second is the Mk3 pumping module, which is 16 times as fast as the Mk2 version, while retaining its ability to run 4 recipes at once.

The tier 4 Quantum Force Transformer is unlocked with UMV components and a running Tier 3 QFT, and unlocks three new line skips immediately:

• Radox/Kevlar
• Bio Catalyst/Mutated Living Solder
• Seaweed

The Radox skip is especially valuable, due to how slow the standard Radox recipe is and how much is needed for UMV and UXV circuits, although making a tier 4 QFT requires over 1.6 ML of Radox first. The Bio Catalyst recipe is also very useful, and these two recipes combined should make the tier 4 QFT a priority upon entering UMV.

It is also required to run the Eternity loop after reaching a Tier 7 Eye of Harmony, and for the Z Boson, Lambda, and Omega particle recipe that is needed for the Stargate.

The Giga Chad Token is an item that can be made in UMV to complete a quest and for bragging rights, and is otherwise only used in the Stargate. It requires a stack of UEV, UIV, and UMV Field Generators, 100ML of Exotic Catalyst, and some SpaceTime in the DTPF, and takes 48 hours to craft without any overclocks.

UMV contains the third old Stargate trophy, the Stargate of Dimensional Duplicity, corresponding to version 2.2.3. This old Stargate is very expensive on UMV circuits and components, in addition to many of the components used in previous old Stargates: it requires 167k Bio Mainframes and 21M UHV Superconductor, like the UEV old Stargate, but also takes 820ML of SpaceTime, 142k Pico Circuits, and 65k UMV Motors. It also, like the UEV Stargate, requires Assembly Line recipes that are both very slow and need UXV power, meaning they cannot be run in the Advanced Assembly Line until the next tier.
