My currently running motherboard called as MSI 890GXM-G65 in my computer has 2 PCI-E slots. I had it earlier than on bottom one contiguous to PCI slot and inspecting gpuz it supposed it was running at 8x. Currently i tested it on top of foremost PCIe slot one nearby to CPU and it seems to be operating at 16x. Now I don’t have any idea which slot I should use. It is really a confusing matter for me. There is no such manual for this puzzle.
Below arê the complete specifications of PCIe slots in MSI 890GXM-G65 motherboard:
- PCI_E1 slot through x16 operation (PCI Express Bus SPEC V2.0 compliant)
- PCI_E2 slot by way of x8 operation (PCI Express Bus SPEC V2.0 compliant)
- Note: While 2 PCI Express x16 slots are all installed, the PCIE x 16 paths will auto assemble appearance x16/ x0 toward x8/ x8. Do not make use of PCI_E2 slot while only single PCI Express x16 card is installed.
- Single PCI Express x1 slot
- Single PCI slot, with the support of 3.3V/ 5V PCI bus Interface.
The micro-ATX form issue is receiving more and further favor intended for budget motherboards since it saves a small number of quid on top of physical resources, and up-sells the ATX format as well. In spite of this, MSI has at rest compressed two 16x PCI-Express 2.0 connectors, which routinely set themselves toward 16x-1x otherwise 8x-8x based on whether extra PCI-Express cards are utilized or not. There's not a degree of additional space among a couple of dual-slot cards although, therefore ensure you have a case with respectable airflow.
I ran 2 tests of every PCI-e slot #1 x16 as well as #2 x8 by the use of 1x4870x2 GFX card. I averaged the consequences of every 3 run set to locate the test outcome intended for each one PCI-e slot.
The processor at 4551MHz 1x4870x2 @778/980MHz Windows Vista 32-bit
PCI-e slot #1 average of 3 analysis
- FPS=104.6
- Score=2630
- Minimum FPS=53.6
- Maximum FPS=207.4
PCI-e slot #2 average of 3 analysis
- FPS-101.8
- Score-2576
- Minimum FPS-52.4
- Maximum FPS-205.9
I can’t say that which card you should use because I have never used the board so far now. But I advise you to take any old Graphics card or maybe any new card and install it on any of the compatible PCIe slot. Afterward install the GPUz and some benchmark program to get the score of either the card or may be the PCIe slot. Run more than 3 times and verify the result. Also compare the same result with other result which you have got in other computer with same board or with same card. Now you can decide it by yourself.
As far as I know the MSI 890GXM-G65 motherboard comprises support in favor of DirectX 10.1, ATI Hybrid Crossfire, ATI CrossfireX intended for installing 2 elevated performance ATI graphics cards, USB3.0 as well as native SATA-III (6Gbps) for utmost data transports speeds. Here are the number of slots included in the motherboard.
- PCI-E x16 ---2
- PCI-E Gen ---Gen2 (1x16, 1x8)
- PCI-Ex4 ----N/A
- PCI-Ex1 ----1
- PCI ---- 1
