While Advanced Host Controller Interface (AHCI) interface has the benefit of legacy software compatibility, it does not deliver optimal performance when an SSD is connected via PCI Express bus. This is because AHCI was developed back at the time when the purpose of a host bus adapter (HBA) in a system was to connect the CPU/memory subsystem with a much slower storage subsystem based on rotating magnetic media. Such an interface has some inherent inefficiencies when applied to SSD devices, which behave much more like DRAM than like spinning media.
At a high level, the basic advantages of NVMe over AHCI relate to its ability to exploit parallelism in host hardware and software, manifested by differences in depth of command queues, interrupts processing, the number of uncacheable register accesses etc., resulting in various performance improvements. For Win. 7 and Server. R2 users Microsoft is offering an NVMe driver as hotfix, which can be downloaded from > here< (thanks to rootuser. Nearly all mainboard manufacturers are meanwhile offering new BIOS versions with full NVMe support for their mainboards with an Intel 9- Series or X9.
Premium Gold Caps, Digi Power Design, 8 + 4 Power Phase Design, Supports Dual Channel DDR3 2800+(OC), 2 x PCIe 3.0 x16 Slots, Supports AMD Quad CrossFireX. On this page we compile an overview of all the Z170 Non-K Overclocking enabled BIOSes from ASUS, ASRock, GIGABYTE and MSI. Updated regularly!
Chipset. Many consumer SSDs with NVMe support are already available or will be available soon. There is no doubt, that users with an up- to- date mainboard, whose original BIOS contains the required NVMe modules, will benefit from the performance boost initiated by a new NVMe supporting SSD. But: What about the Intel 6- 8 Chipset Series mainboards without such NVMe support given by the mainboard manufacturer? Is it possible to give them the required NVMe support by modding the BIOS?
If yes, which modules have to be inserted and how has it to be done? These were the main questions, when I started this thread in April 2. Although we do not yet know everything, we made in December 2. That is why I have completely updated the below part of this start post.
Since February 2. AMD Chipset systems as well (look > here< for the report written by our Forum member Anti.
Bear). Guide about how to get full NVMe support(probably valid for all systems with an Intel 6- /7- /8- /9- Series or X7. Chipset)(last updated: 0.
This is what you should know: It is no problem to get a PCIe or M. NVMe SSD working with any Intel Chipset system from 6- Series up without modifying the mainboard BIOS, if a) the NVMe SSD will be used for the storage of data (as drive D: , E: etc.) andb) an appropriate NVMe driver is present within the Operating System (either natively or loaded/integrated),but the usage of such SSD as bootable system drive C: (incl. If it should not yet been shown within the pop- up window, choose the file type option . Now you should see the main contents of the BIOS inclusive the most important . The easiest way to find it, is to use the . This is what I recommend to do after having opened the source BIOS with the UEFITool: Insertion of the NVMe module. Once you have expanded the DXE Volume, scroll down to the undermost module, which is listed as .
In this case it may be necessary to remove another . You can start it either by clicking onto . Vw Navigation Dvd Rns 510 V8 Download Games.
Then you can navigate to the folder, which has been designed for the modded BIOS (e. D: \Mod BIOS), choose a meaningful BIOS file name with an appropriate suffix (you can use any suffix, if you choose the . PCIe slot, which offers the best possible performance and doesn't share the PCI lanes with other devices (please look into your mainboard manual). Important: The . Make sure, that the . After having done that, let the Win. Setup create a new partition for your future drive C: on the related SSD. Then point to this just created partition as the desired future OS location.
The rest should be done by the Setup automaticly. You will get a message, that some additional partitions have to be created. Accept that and follow the advice of the Setup where to install the OS.
Once the OS is up and running, shut down the computer, remove the bootable USB Flash driver and reconnect all your previously used storage drives. Before you restart cour computer, make sure, that the NVMe SSD resp. After having inserted the NVMe EFI module into the BIOS, the formerly used SSD should be removed and the NVMe SSD inserted. Good luck! This is what you hopefully will get: Here are some benchmark results I got with my Z6. NVMe supporting SSDs: 4. GB Intel 7. 50 PCIe SSD: 2.
