@Lost_N_BIOS The M.2 is no more shown in bios now, i can see in the OS and write/read but in the bios section it disapeard, WIN10 installation shows and install.

@yabay - great it's working now! Yes, Crystal Disk and AS SSD use compressed data for testing, you can set zero fill on crystaldisk if you want >> File >> Test Data >> All 0x00 (0 Fill)

I've take out and cleaned my graphics card, when i installed it again to the case, it didint worked and i gave a bios reset, then i lost my m.2 in the bios of this, when i updated the bios again from your mod file, its ok now can seen by bios runs with no doubt except speed issue..

"@yabay - great it's working now! Yes, Crystal Disk and AS SSD use compressed data for testing, you can set zero fill on crystaldisk if you want >> File >> Test Data >> All 0x00 (0 Fill)"

now i've tested my corsair force series 2x raid0 ssd's with crystal diskmark, they gives about 900mb/s in first time using after installation, then programmes added 700, but atto gives 1050mb/s everytime, In M.2 bench, crystal and atto gives similar (390mb/s)

Edit:

No nothing changed with All 0.00 (0 Fill), although M.2 is in sotrage mode now and gives 350-400 mb/s :/

Besides, Lost_N_BIOS, the integrated module version can cause this speed restriction in the bios? Is it worth to try a nother module? If M.2 cant reach 1000+, our effort will become useless.

(can you see my image link?)

@yabay - yes I can see your image link. Module is inserted correctly, there is no other modules to try.

Some boards split graphic card lanes with SATA Lanes. How are you connecting the device? If PCIE slot, try putting in the top x16 slot and retest, the other slot is only x4. Or are you using the mSATA slot?
Make sure no other SATA device on last two SATA Ports on the Intel controller (4/5) Then test with using onboard graphics only, or with a PCI graphic card, so all PCIE Lanes are free
I checked manual, and mSATA slot only has SATA II (3Gb/s) speeds.

What main speed and lane speed does the device show up as in CrystalDiskInfo (Show image)

Nvme drive is connected via PCI-E X4 M.2 adapter card, I changed the nvme with graphics card, the GTX 580 didint gave a post screen in Pci-e 16 X4 slot.

Use onboard graphics for a test, or old PCI graphics card. Or did the 580 work, boot to OS, just not display POST Screen (That might be normal, give it a bit, reboot a time or two, then see if it will boot to OS or not)

Show me image of CrystalDiskInfo, be sure to select the NVME drive. The only thing sharing bandwidth with the x4 slot that you might be using is the LAN

Looks like 1500ish may be the average limit of PCIE 2.0 x4

Did you test setting PCIE Gen2 instead of Auto on the miscellaneous settings page (Or Gen3 if using IVY, but I think this would only help the x16 slot run 3.0)

in X4 lane GTX 580 didint gave any screen, and a vierd beep heard. PCIE gen 1,2,3 auto tested, results are exactly same.

I've tried my old spare 8500gt standalone boots in X16 slot, but not 8500gt nor the gtx580 boots in the X4 lane




I have all these adaptors, tried all, no change.

Thanks, CrystalDiskInfo shows it's only running at x1, that's the issue. Are you sure those adapters are x4 speed, not just x4 physical connection?

@ Uefi, tried all combinations. No change.



Yess i'm sure all adapters are X4. Ok its running X1 now, but before the uefi upgrade how can i tested 1150Mb i dont understand.

This card is Pcie 3.0 x16 and reversable to standarts, and connected with m.2 in the crystaldiskinfo.

I have an OCS REVODRIVE 3 too, for 5 years it works in the X4 slot with no doubt.



I'll try to connect the revodrive and see if there is a different info in the diskinfo.

Windows boot mode, UEFI, etc have nothing to do with this, so don't waste your time there. The main issue I assume is this BIOS is extreme beta, Gigabyte's early first jump to UEFI and they made it hybrid/legacy, half of it doesn't work properly, and they gave up due to Z68 came out right then too so all UEFI progress moving forward was on Z68 and a few other P67 boards got 1-2 more beta like this one but none ever fixed the main issues (and this probably one of those, nobody noticed back then due to no one using NVME then)

Your best option is to go back to legacy type BIOS, and use Clover

* Just saw your edit. So the Revo works properly, full speed in benchmark, and x4?

This is so sad even with you priceless reccomendations :/

revo used to give 1000mb/s in legacy, in uefi its restricted too..

REVO drive shows up as SATA 6Gb/s, no PCIE Speed is shown? See if this app will show you REVO lane width being used
Utility to view some info on PCI devices

What CPU do you have installed, if Ivy, do you have a Sandy one to try? Some CPU Ivy or Sandy worked better on the UEFI than others, but it depended on what you were trying to do. If you have both, try other and see if same, if it's same, best bet is to go back to Legacy type BIOS.

Revo posts Pcie speed during post screen (as seen above, black one) According to post it shows X1 5Gbp/s

I have only 1 cpu, i5 2500k sandy.

x1 but 5Gbp/s sounds like something "Marvell"

Best to use legacy type BIOS for Sandy Bridge CPU, so your best bet it go back to legacy and use Clover method for your NVME.

Did you test NVME in x16 slot, use onboard graphics and see how the NVME speeds are there. Of course if that worked, it would mean you'd have to stay on integrated graphics to use it like that
But it would be interesting to know if it shows up full x4 speed like it should or not.
