Hi,

I finally managed to get my two Adaptec 4805SAS SAS PCIEx4 8 Channel controller cards to work, all thanks to the P6T Deluxe.

Previous attempts to get these up and running meant that I had to lose the onboard SATA controller, on whatever socket 775 board I tried these on, first time I plugged these in, they worked from the start and no other controllers conflict at all, saves me having to buy a server board for these to actually work on at least.

Thought i'd share this, would love to know the driving force behind why it is now possible, i'm thinking the maybe the QPI to thank for this?, anyone have any ideas?

Why wouldn't you use the onboard SAS vs. installing SAS controller cards? Was it only to have the ability to run more than 2 SAS drives?

SAS is different then SATA black.... the P6T-DLX doesnt have onboard SAS, only onboard SATA. now it could work cause of a change with the ICH/SB that is used, there is really no telling.

hmmm... they advertise onboard SAS am I missing something?

hmm weird, last time i looked at it, sas wasnt listed...

p6t deluxe v1 has SAS controller, p6t deluxe v2 doesn't

Yea sorry, it was the v1 board with onboard 2-channel SAS.

The last time I checked these cards were like £900 each, but I spotted them with a bunch of other old VGA cards selling for £5 and jumped at them, that was about 5 months ago, I bought some SAS to 4x SATA cables off ebay for like £12, but I couldnt get these cards to work in my then rig without losing the onboard SATA controller (which held all my RAID's at the time), tried moving from X38 to X48 but still no good. So put them to one side.

I've bought this P6T Deluxe v1 since, tried them in here and they work like a charm with all the oboard SAS, SATA controllers working also...fantastic!

I'd love to buy a whole bunch of SAS drives to really give these cards a workout, but for what I paid for these i'm content with just expandability for extra SATA HDD's(16 SATA drives on the two controllers +8 on the P6T dlx(incl 2ch SAS) = 24 SATA Drives) for now.

I thought the X58 NB was just an X48 NB but with the memory controller stripped out, if this is the case then is it because the CPU's IMC can allocate the resources better than what the X48 NB could do?

Or maybe the QPI having higher throughput than previous interconnects to handle the added load of the cards?

Any ideas?

two things either the added load is stressing the PSU or possibly the BIOS of the raid cards is overriding the onboard controller.

Thanks for the suggestions Adrgontattoo, but my attempts on the X38 & X48 were with the same 950W PSU, all at stock voltages with a Q6600 so i'm doubting the PSU is the problem.

On the RAID cards I can enable/disable the boot BIOS which would allow for onboard RAID to also work, but it always disabled the onboard RAID on the X38 & X48 no matter which setting or PCIE slot I tried, whereas with the X58 board, both just work from the beginning, so I can't see how the card can be over-riding the ICH10R controller on the X38 & X48 without is doing the same to the X58.

I understand so far the the ICH10R is basically the same for the X38, X48 & X58?
Could there have been tweaks made for the X58's ICH10R controller for the X58, but wouldn't they have called it the ICH11R or given it some mad revision number?

Anyone have any other ideas/suggestions?
