Thanks for the info, I don't think raid 5 is needed if I'm striping 3 drives in raid 0 (I guess it's just giving up the options for in the future).

Why doesn't the card have a heatsink? Is it due to the fact it isn't a full blown PERC 6, or should it have one and I need to get one installed?

Is a BBU really necessary for raid 0, or is that dependent on the write setting still?

The card doesn't have a heatsink because it doesn't have a REAL processor onboard - the main chip is the SAS controller. Raid 1 and 0 (which are the only ones supported by the card) don't really involve any processing, and so the SAS controller handles it all. If you find the chip gets hot you might like to glue a heatsink on, but it probably won't be necessary.

The card also does not support a battery at all, and one isn't necessary as it has no onboard cache. It will run fine in RAID 0, not sure how speed will compare to the PERCs, but it should be pretty quick with a few decent SAS drives on it (make sure you enable the drive cache though - this might be disabled by default). Caching with no BBU is generally a bad idea, but as you are running RAID 0 with no redundancy anyway I think the performance benefit should be worth it.

I cannot get into the CTRL - <R> config screen it just hangs when I try also none of my 4 1TB WD Green drives are found on boot up.

Think I need to tape up the pins? Any ideas greatly appreciated.

Running firmware 6.1.1-0047

Thanks

Edit - Just checked and there are 2 types of cables that shipped with the card one a straight connector the other a right angled. Have tried both but still no joy.
Tried the tape mod on pin 5&6 no go. After hitting ctrl -r it sits there for ever saying pls wait

Hi All!

I have done a lot of reading through this thread, so my apologies if this has already been answered.


I have an Abit IP35-Pro, which has 2 PCI-e slots; one 16x, and the other 4x when using the first slot (which I am).

I want to get a Perc5i for my system, but I am very concerned about the compatibility of this card with my mobo. I have seen conflicting reports, alot of them here. I know about the tape fix, which helps with intel based boards, but can anyone confirm that this card DOES work in a IP35-Pro, and if so what you need to do to get it to work (tape mod?).

Thanks!

Tape trick used (actually pink nail polish?)

Abit IP-35 Pro, bios 14, LSI firmware, works great!

If I had $1200 I could get 6 new Seagate 450GB 15k SAS drives through Seagate partner program. I will pick up a 7200.12 1TB and a 500GB 2.5in drive for around $100 for both. I can only get 1 of the SATA drives and 6 of the SAS drives.

Wow thanks for the info beast

I think I'll go for it, I should be able to get it for under $60US delivered. I have all my important data backed up, so worst case scenario is I have to replace a drive and re-image everything.

Thanks again for the info!

Thanks

I was running 3 15k 73GB in Raid0 before I moved the Perc5/i card to another machine. I am now running 2 WD 250GBs single platter drives in Raid 0 off the intel controller and I can notice no difference at all in speed and boot times. The benchmark is slower and I have notice no difference in applications speeds. If you havent gotten these drives I would go SSD. Just my 2 cents.

Hi, everyone, need some help.

This is very weird.

I have a system that's using ABIT IP35 Pro XE with Intel Matrix RAID.

I decided to upgrade the system to use Dell PERC 5i SAS controller. After masking pin 5, 6 and installed the driver, flash the LSI ROM, the system recognized the new RAID 1 disks, which are 2 WD Raptor 150GB 10,000 RPM SATA drives.

However, I was unable to format the virtual disk with NTFS and it always gives me error message "Windows was unable to complete the format" after 99% formating.

Later I found that it was because Windows SBS 2003 R2 was unable to format the disk since it's larger than 137GB! Isn't this a limitation back in Windows 2000?

If I make the partition less than 137GB, than it formats perfectly.

The weird thing is that I have another 500GB disk right inside the system. So how come Windows 2003 was not able to format this new RAID array?

Any idea?

*EDIT*

problem fixed by install XP on 500GB disk and install PERC driver and then use Acronis to delete and format the partition. Now it works under Win2003.
