GB UD3 x79 gpu -> PCI-E 2.0 anstatt 3.0 ?!?

[bigred]

Moin,

GPU Z zeigt mir an, dass ich nur PCI-E 2.0@16x verwende. Das Board sollte laut Hersteller jedoch 3.0 können: GIGABYTE - Mainboard - Socket 2011 - GA-X79-UD3 (rev. 1.0)

"2 x PCI Express x16 slots, running at x16 (PCIEX16_1, PCIEX16_2)
* For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot.
2 x PCI Express x16 slots, running at x8 (PCIEX8_1, PCIEX8_2)
* The PCIEX8_2 slot shares bandwidth with the PCIEX16_2 slot. When the PCIEX8_2 slot is populated, the PCIEX16_2 slot will operate at up to x8 mode.
(All PCI Express x16 slots conform to PCI Express 3.0 standard.)"

Woran kanns liegen?

Welche CPU?

Der 3930k siehe Sig?

Sandy Bridge-E kann nur PCIE 2.0: https://en.wikipedia.org/wiki/LGA_2011#Compatible_processors

Bin fündig geworden.

3930K Rev C2 kann PCIe 3.0


Man muss den Rotz erst manuell per registry "freischalten".. jetzt gehts auch und steht im gpuz als 3.0 @ 16x ..


Copy pasta:

Enable it manually via regedit...

#1 Press windows key + r to bring up the run box.

#2 Type regedit and hit enter.

#3 Goto HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Video

#4 Identify the correct registry folders for each of graphics cards you have installed. There will be one associated folder for each card installed. To identify the correct folder for each card, you will need to review the names of each folder within the “HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Video” registry directory. The folder associated with a graphics card will have three or more subfolders (depending on how many PCI-E slots available on the motherboard). The values listed for each subfolder will be 0000, 0001, 0002, 0003, 0004, and Video. Review only the subfolders labeled as "0000". You will know you have selected the correct "0000" subfolder when you see a registry labeled “DriverDesc” with a value that matches the graphics card you have installed.

#5 Right click on the folder labeled “0000”. Select “New”, then select “DWORD (32-bit) Value“, then enter “RMPcieLinkSpeed” for the name of the registry.

#6 Right click the “RMPcieLinkSpeed” registry you just created, then select “Modify”, then enter “4” as the data value and verify that the “Hexadecimal” option is checked under “Base”, and then select “OK”.

#7 Repeat steps 5 and 6 for each graphics card associated folder (named “0000”)

#8 Once you have completed creating the RMPcieLinkSpeed registry for each card, close the Registry Editor window and restart your computer.

#9 Once your system is back into operating system environment, run GPU-Z and verify that the “Graphics Bus interface” value shows PCI-E 3.0 for each card.

Hat bis jetzt immer einwandfrei funktioniert


Funzt auch mit Rev C1

Nur weil dir PCIe 3.0 angezeigt wird, heißt das nicht das die CPU auch damit läuft.

Die Datasheets zeigen nichts an von wegen PCIe 3.0 bei Sandy.

Erst Ivy bringt PCIe 3.0 mit.

Jain. Die Datasheets zeigen nichts an, richtig. Jedoch inoffiziell kann Sandy-E eben doch PCIe 3.0, auch wenns nicht da steht.


"The PCI Express controller in Sandy Bridge-E has one more distinguishing feature: it supports 8 gigatransfers per second rate, i.e. meets the PCI Express 3.0 specification requirements. However the current Intel processors haven’t been certified yet that is why in most cases PCI Express 3.0 compatibility is not officially stated."

Du wirst aber keinen spürbaren Unterschied fest stellen bei PCIe 3.0 gegenüber 2.0 .
