Yea, but such slots (PCI with 64 bits and more then 33Mhz speed) exits only in server motherboards, which unsuitable for gaming... and such mobos usually already have PCIe 8-x slots anyway. Unless really old, of course.
I really doubt that such converters exist, too. Adding an extra peripheral that may cause instability into a server does not sound like a good practice at all - specially there is plethora of PCI-X RAID and whatnot cards of all kinds avalable.

I finally got my 5/i installed and running with 2x IBM/Hitachi 146gb 15k SAS drives. It runs perfectly on an X38 asus maximus formula using the pin 5&6 tape trick.

Check my HDtune benchmarks below.

This is running pretty much stock with a 1mb stripe (not sure if 1mb is a bad choice, advice anyone?)

But to report, I'm, most impressed with the performance:

read performance:

file benchmark:

now looking for a non raided SAS system drive and dedicated sas 15k swap drive, probably an old 36gb sas.

Hope this helps. The 5/i is definitely worth buying in my opinion.

SAS is awesome

And if I was you I'd definitely decrease that stripe size to about 16kb, those drives are fast enough to handle it. The tradeoff with stripe size is that lower stripe = smaller files get broken up more (and therefore faster to read) but large sequential transfers might take a small hit. Either way, anything larger than 128kb is only for very unique applications.

I am a little sad because i see reports of my mobo "p5w dh deluxe" not working with these cards

*EDIT*
Fixed a typo

The card supports 8KB, 16KB, 32KB, 64KB, 128KB, 256KB, 512KB, and 1MB stripe sizes.


I'm doing read/write benchies still.... 20MB/s average read improvement over ICH9R in 3xRAID0.

It turns out that defrag performance isn't affected by RAID much at all.

I'm just going to end up with 15-18 Read/Write benchmark sets.


Did they do the 5+6 pin mod? It should work then.

When I installed it, I noticed it installed drivers for 2 PCIe bridges. I know the chip to the left of the ARM processor is a PCI-> PCIe bridge chip.

here's my hdtune read (the write test gave an error, as it said i had to remove the partitions, of which i have only one... ) :
edit: this is with 8x36gig 10krpm sas, raid0...128kb stripe

@sumilux: after trying the many stripe options, 128 worked best for me: stand alone workstation for CS3, some rendering, tossing avi files about. i wouldn't go below32k, unless you are doing some sort of mail server thing. i found 64k to be a sweet spot for medium size file usage (this is the default for the lsi hba i have ran, i forgot if the perc was at 64 when i first fired it up...). 128k gives me speed for what i do, and seems to show up well in these type of tests. love that low access time you got there

Benchmarks are up... it's a lot to digest.

Whar?!

Oh, OP...

~Gooda~
