Pc Zusammenbauen?

Hello

The strongest thing you can get at the moment for a gaming PC would be a Ryzen 7800X3D processor and a RTX 4090 or RX 7900XTX graphics card.

However, an RTX 4090 does not fit into your reasonable budget, as this alone already from approx. 1800,-€ upwards. With an RTX 4090, only a low budget PC would be possible, which makes no sense.

And processors with even more cores do not offer any more performance in games, as for games the single core performance is still crucial.

Whether this is enough for all games with 120FPS, also the future ones, but I can’t promise you, but for most games it should be enough, or sometimes more than enough. You will not be able to get much more performance for games at the moment, even if you use more money.

That’s why I would recommend a Ryzen 7800X3D processor that doesn’t pose any problem with your budget and a 32GB DDR5-5200 Dual Channel RGB RAM Kit, a 16GB RTX 4080 Super graphics card, a B650 ATX AM5 motherboard, a 2TB M.2 PCIe 4.0 x4 SSD, a 750W BeQuiet 80+ Gold power supply and a relatively high-quality fan ATX case with ARGB.

However, you can only get to just about €2100,-, i.e. to about €400,- under your budget ceiling. What you’re doing with the rest of your budget is your thing. The hardware should be enough to be able to hold almost all games in 4K UHD resolution.

A Windows license is still missing, which should be purchased separately if necessary.

In addition, I recommended “only” a single 32GB DDR5-5200 Dual Channel RAM Kit, because this makes the processor specifications optimally used, which ensures the best possible performance, while at the same time the highest possible stability.

Declaration: (if you are interested in why this is so)

The achievable storage speed no longer depends solely on the mainboard and the RAM modules, as in the past, but especially on the processor.

But in turn. Let’s start with the motherboard and then we start working slowly to the processor.

The data in the motherboard specifications are, as is repeatedly mistakenly assumed, not guaranteed memory speeds, but there is only what memory speeds can be set at the memory controller by the BIOS/UEFI of the motherboard, including the memory speeds that can only be reached with the overclocking of the memory controller.

Storage speeds that can only be achieved via overclocking, which are usually characterized in the motherboard specifications as follows: (OC), (O.C.), (by A-XMP OC Mode) or (EXPO)

Therefore, the data in the motherboard specifications also do not mean that the memory controller must run as naturally with all adjustable storage speeds, especially not with the storage speeds that can only be achieved with the memory controller overclocked.

The memory controller is now in the processor and not somewhere on the motherboard and also not in the RAM modules. And there in the processor, the storage speed is now set by the BIOS/UEFI and not somewhere on the motherboard and also not on the RAM modules themselves. The memory clock then results only from the number of accesses per second to the RAM. Otherwise, the RAM itself is not clocked and does not run independently at any speed. However, it is also the processor that is responsible for the actual memory speed and not the motherboard and RAM modules alone.

However, the RAM modules also have to be able to maintain the storage speed set at the memory controller. They must therefore also be designed for the storage speed set at the storage controller. This is specified by the memory profiles which bring the RAM modules and are configured according to their specifications by the memory controller, in the processor used, by the BIOS/UEFI.

These storage profiles also include the XMP or, more recently, EXPO on DDR5 platforms. The XMP or EXPO is determined by XMP or EXPO overclocking RAM modules and can then be selected and activated in the BIOS/UEFI. These RAM modules are then even overclocked to their intended speed via XMP or EXPO. However, the storage speed is also set at the memory controller in the processor and not at the RAM modules themselves.

The storage controller in the Ryzen 7 7800X3D AM5 processor is just like all other Ryzen series 7000/8000G AM5 processors also, designed for operation with up to DDR5-5200 RAM modules, when fitted with a storage bank (rank) per storage channel. This can also be read in the specifications of the respective processor.

Max Memory Speed:

2x1R GDR5-5200

2x2R GDR5-5200

4x1R – DDR5-3600

4x2R – DDR5-3600

• 2x1R – Dual Channel with 2 Single Rank (1R) RAM Module
• 2x2R – Dual Channel with 2 Dual Rank (2R) RAM Modules
• 4x1R – Dual Channel with 4 Single Rank (1R) RAM Modules
• 4x2R – Dual Channel with 4 Dual Rank (2R) RAM Modules

For storage speeds in each case, which can then also be used with faster RAM modules, the memory controller is also forcibly overclocked in the processor used, which can function, but which does not have to function in advance guaranteed and which somewhat reduces the life expectancy of the overclocked components. This would then affect memory controllers, i.e. the processor, and the XMP overclocking RAM modules. The same applies to AMD EXPO RAM modules introduced with the AM5 platform.

In addition, the maximum achievable storage speed decreases, the more storage banks (rank) are used per storage channel. This is due to the additional load of the memory controller by more memory banks and to the physical properties of the memory bus in the high-frequency range. It is easier to say that higher storage speeds can be achieved with two RAM modules, as with four RAM modules. This should be considered especially at MEM overclocking.

A memory bank is not always a RAM module. There are single rank RAM modules, since one memory bank corresponds to a complete RAM module and there are RAM modules on which are already two memory banks. These are Dual Rank RAM modules. A Dual Rank RAM module is roughly the same as two single Rank RAM modules used in single channel configuration.

Therefore, it is also more likely to work on an AM5 motherboard with 4 RAM slots, 4 DDR5-5200 RAM modules, than 4 RAM modules with higher storage speeds, which then restricts or at least complicates the possibilities in RAM.

It also plays no role, which can still be set to such a high memory speed from the BIOS/UEFI of the motherboard, at the memory controller in the processor, and for which the RAM modules are still designed so high, because if the processor does not play with the MEM overclocking, then it is still vinegar.

Whether and how high the memory controller can be overclocked in a specific processor cannot be predicted, because this depends on the individual properties of each individual processor, also from the same series. One can do more and the other can’t stop. This means that even if the MEM overclocking works with other functions that cannot be closed from it, which must be the same in any further case.

The motherboards have been successfully tested with the storage speeds specified in the respective specifications and the RAM modules that have managed this are now also found in the Memory Support list (QVL) to the respective motherboard, but for these tests the motherboard manufacturers use specially selected engineering sample processors. Processors for the end customer market usually create these storage speeds not or only rarely and also not under warranty with the RAM modules from the memory support lists. Even with these RAM modules, the specified storage speeds are only reached when the inserted processor plays along, that is the condition.

If now, for correspondingly fast RAM modules, a higher storage speed via XMP or EXPO is set when the processor is natively supported, i.e. without overclocking the memory controller and the computer should then run unstable or no longer start after the XMP or EXPO was activated by the RAM modules in the BIOS/UEFI, then the simple MEM clocking worked via XMP or EXPO not because the settings by the XMP or EXPO is too good for the processor.

In this case, the storage speed would have to be manually engaged to set the storage speed. There may also be several XMP or EXPO storage profiles available, one of which might work. Otherwise, the storage speed, with activated XMP or EXPO, can be additionally manually throttled until the processor is stable with it or the storage speed, the timings and the RAM module voltage are completely manually set. Have fun.

Since overclocking, by the higher clock and the associated increase in the voltage of the overclocked components, increases the effect of electromigration, ages overclocked components faster, which in the case the XMP or EXPO MEM overclocking RAM would affect the memory controller in the processor. Precise predictions can not be made either.

By overclocking, the computer can also become unstable or no longer function. See also here:

That’s why I guess from overclocking.

If you still want to try MEM overclocking, with storage speeds outside the CPU specifications, to use these storage speeds with correspondingly fast XMP or To be able to use EXPO RAM modules and possibly also with more than two RAM modules, you can do this with all the problems that can arise from them. This is your decision and not my recommendation.
