It could be the cable yes.

Possibly shorting on the VRAM, or dying VRAM.

Unfortunately, even that tool is not 100% certain that TRIM is properly working as has been discussed in some other TRIM discussion forums, but most likely TRIM is working on our m18xr2's in win7.

This was posted by user Sy5tem on NBR but seems to be a good idea:

it looks like the HM77 (m18x-r2 ivy bridge) support TRIM, but TRIM is disabled in the OPROM by intel...

i have read on another forums that people have unlocked the oprom for series 6 e.t.c ..... ( AnandTech Forums - View Single Post - RAID0 trim and SRT seems possible on 6-series and 5-Series )

now to unlock TRIM support on the M18X-R2 it seems we would have to edit offset 1bb22 and add 071E000007 to replace the entry and enable trim on the hm77 raid...

i know that the hm77 as controller ID of 282A and alternativeID of 1E07 that is the number needed and needed to be edited in a oprom...

i do not have the skill knowledge and tools to do so... but i know somebody here probably would!

can anybody mod the OPROM with those info, and merge it into the m18x-r2 bios so i can test if it enable TRIM on the m18x-r2?

Would this be possible on the m18x r2 bios svl?

The esata-usb port combo on the right side topmost is controlled by a bios setting as Suoah has mentioned. It is a usb combo port not just esata, and is the only one controlled by the bios setting.

You can also flash your ram using thaiphoon burner to a higher speed for some modules. I did this to make my hyperx 1866 run at the timings and frequency of the hyperx 2133mhz with no increase to voltage needed.

Try disabling agressive LPM in unlocked bios, and also enabling hotplugging. These disable power savings feature of the ssds.

Replied to you via PM, svl7's vbios files are great as well.

svl7 is very awesome.

I see no issue with the boot text, its his work, if someone does not want it they can flash to other vbios.

New firmware has been released for optical drives for this on dell page.

triple heat sink has more copper which provides greater heat transfer.

Yes you can, just use the original dell bios.

We await a undervolt / stock vbios (0.962v or lower) + unlocked for 680M m18x r2

1 thing you can do is use nvinspector to import latest sli profiles via text file when using an older driver. That way you wont be missing much. Here are the profiles from 314.14 driver.

Could be that the cable is not seated deep enough due to m18x's deep hdmi out port. Possible it just barely is or partially touching causing these issues.

Provide us BSOD code if you can.

A09 has updated OROM, no need to blind flash either using svl7's amazing tool (after flashing stock A09 to upgrade EC)

Wei score probably has some polygon/geometry computation aspect to it where AMD is superior, but all in all 675M will perform better in gaming. WEI is also a flawed test.

Here's my personal best so far. I think I've finally gotten past the major hurdle that was blocking me. I just need to tweak some more and should be able to cross 17k GPU shortly if I ever get time: NVIDIA GeForce GTX 680M video card benchmark result - Intel Core i7-2920XM Processor,Alienware M18xR1 score: P13612 3DMarks

Brian what was the hurdle for you?

svl7 has unlocked great potential of the 680M. Amazing work.

No throttling issues here at 935mhz core 1080mhz memory temps hit up to 75 degrees.

For me it seems PnP ram is the way to go, I use 1866 hyperx pnp and have no issues on my m18x r1 and r2.

Awesome man.
