What is your intended use for the PERC? I assumed as you said it was for your server that you wanted a storage array, and needed the onboard RAID to boot (presumably) a RAID1 OS array from. Your Highpoint card is also likely faster than the PERC in all respects (although may have issues with some SATA disks due to the IOP348), so if you need speed you would probably be better with that.

You can try the pin mod (check the OP), although if your board is ok with the PERC in the x4 slot it would be odd if it has SMBus problems with the x16/8 slots.

If that fails, maybe try a few different versions of mobo BIOS & see if you can boot it?

I'd just like to thank all those who helped me with my problems and issues a few pages back. It's all working good and I learnt a lot.

Thanks.

I want to cry

Finally got around to putting in my perc 6i in my 3u case and found out it won't fit. The cables coming out the end are too tall. I probably spent 2+ hours looking right angle cables only to give up.

Any suggestions? (and no I really don't want to cut the case)

So it's either one or the other
I have a 5i set up on a P5K-Premium and found I had to move away from the onboard SATA ports completely, and also, do the nail-polish trick.

I now have 2 x drives in raid1 and 6 in raid5 all on the perc and it works fine. I played around for ages trying to get the card to work properly with drives running on the onboard SATA ports, but eventually gave up and went the other way.

LMK if you manage to get it sorted, although I'm moving to a 4tb NAS shortly, so might be redundant anyway.

The ONLY other thing you can do is get PCIe right angle adapters OR PCIe ribbon adapters.

Agreed. I was out of space due to having 2x 4870X2's in my system with another x8 slot available beneath it. Grabbed up a PCI-E ribbon cable and my PERC-6 is chillin on it quite nicely standing sideways. You could easily pull off a similar feat with a ribbon cable/right angle bracket.

Well, now apparently the Perc won't work at all, and I have no idea why. I did try 3 different BIOSes too (and I already did the pin mod).


I dunno, I'm gonna try messing around some more, maybe try disabling the marvell controller or something.


Edit: Ok this is weird, I put the card back in, booted up the PC and voila everything works. lol I'm so confused now.

Above is my HDTune benchmark for my RAID 5 which I was hoping would perform a little better. I'd appreciate any insight in how to improve it's speed.

RAID setup is as follows:

PERC 5i in first PCIex slot of ASUS P6T with pin mod + BBU attached
PERC 5i watercooled with Gigabyte Blue Eye as per this forums guide
Using stock 256MB DIMM
7x 1.5TB SATAII 7200rpm Seagate in RAID 5
Adaptive Read Ahead
Write Back
128kb stripe
Latest LSI driver for Vista 64: 2.20.0.64 (Have tried Dell version with no change in performance)
Latest LIS Firmware: 1.21.230-0598

System Setup is as follows:

ASUS P6T Vanilla
i7 950
12GB Corsair DDR3 CL7
Toughpower 850W PSU
9800GTX+ in second PCIex slot
2x Samsung 320GB Onboard RAID 0 for boot drive
Vista Ultimate 64 Bit

Notes:

The purpose of the system is for editing and compositing footage from the Red One 4K camera. The footage is 4096x2048 in resolution and is very demmanding on both processing poser and hard disk speeds. The file system of teh camera is a FAT32 variant and as such, files are gegmented every two gigabytes. So it is very rare that i am working with files larger than 2GB. That said, i am interested to hear if i have made the right choice in my stripe size of 128kb.

Interestingly, i was able to use the card fine in my P6T without the pinmod, but if i did the system would detect 4GB less of RAM. Soon as i put the pin mod on my full memory showed up. Just thought i would post this for any other P6T users.

I'd say you should make the stripe size much larger. Optimize the setup for larger stripe sizes since most of the files on that raid array will be extremely large. I'm surprised on those speeds though, I'd expect them to be faster.

You might want to consider getting 512MB of RAM on the chip though, it might help (especially if you have 7 very large drives).

ok, ive ordered this: 512MB 1Rx8 PC2-3200R-333/400 DDR2 ECC Registered RAM

from here: http://cgi.ebay.com.au/ws/eBayISAPI....=STRK:MEWNX:IT

as recommended in a previous post. I will post more benchies when it's in...
