Achieving SATA 3 (6 GB/s) speeds with Alienware x51

Hi

I have an "x51" with the following specs:

Intel i7 3770 CPU @ 3.40 GHZ
NVIDIA GTX 670 Gigabyte Windforce OC 2 GB
2 TB HDD
8 GB RAM
700 W OCZ ModXStream PSU

I put "x51" in quotes because my system began life as an x51 but has since been moved to a BitFenix Prodigy case to accommodate the larger graphics card and PSU (I had power issues before). It still has the Intel H61 Motherboard, Alienware BIOS, etc. so for most purposes it is still an x51 - just in a different chasis.

I've recently starting looking into getting an SSD (I have the space given my case change), but I noticed that Intel H61 motherboard in the x51 has only SATA 2 ports (despite the x51 shipping with SATA 3 drives...)

I was wondering whether the following solution would enable me 1) to achieve SATA 3 speeds with an SSD and 2) allow me to use the SSD as a boot drive for Windows. I'm pretty sure about (1), but I'm concerned about (2):

- replace the Wifi card in the mini-PCIe slot with this: http://www.newegg.com/Product/Product.aspx?Item=N82E16816124059
- attach this SSD via normal SATA cables: http://www.amazon.com/Kingston-HyperX-2-5-Inch-SH103S3-120G/dp/B007R67FNA

Can anyone confirm? Thanks!

Won't work it's gotta be a half mini pcie card. Not only that but it's the chipset that controls the sata speeds so it's a no go. I was getting around 250mbs on my crucial ssd on sata 2 on my old setup, so it's pretty faster than a reg drive.

Hmmm. How difficult is it to get the custom BIOS, Commy? Also, are you using it across PCIe as a boot drive - that's my main concern.

And sway, I actually think I have room for the full mini PCIe card since I'm not using the x51 case anymore. My graphics card is seated in the normal vertical orientation now instead of sideways as it was with the x51 adapter.

I've seen a few posts around the net where other people got around the SATA 2 mobo limitation this way. I guess I'll wait a bit and see if anyone else has some input, but thanks for the responses.

Well, pprjr, there is a fairly decent chance I'll go ahead and try it myself in about 2 weeks as I'd get some benefit from a SATA 2 SSD - even if I can't get it working as SATA 3 over mini-PCIe.

I linked an adapter in the OP, but as sway warns, it WON'T fit if you've got a standard x51... mine's special lol.

Still, I'd love to see someone post successful results - or theoretical proof as to whether or not the H61 (with the Ivy Bridge update) can hit SATA 3 speeds and boot over mini-PCIe.

Telophase how did you get the Alienware mobo to work in the Bitfenix case? I tried a different Mini-ITX case and the PSU connector wouldn't fit with the one on the Alienware mobo did you have to do anything special to get it to work?

Jiggerdad:

I did not have to do anything special - the BitFenix Prodigy case and 700 W OCZ ModXStream PSU "just work" with the x51 motherboard (other combinations may work as well; I'm not sure what the critical factor is). Getting the ModXStream PSU to fit in the Prodigy's PSU bay is a bit difficult, but it is certainly doable.

It turns out that I found a nice deal on an SSD, so I bought it and tried using it with the mini-PCIe SATA 3 controller... without success. However, I couldn't even get Windows 7 Device Manager to detect the SATA 3 controller at all, so it's possible that my particular controller was DoA. For now, I'm going to just use my new SSD over SATA 2.

If anyone has a suggestion as to something else that I could try to get the SATA 3 controller working, or proof that it should work, I may try messing with it again. Alternatively, if I really need SATA 3, maybe I'll just upgrade the motherboard someday...
