Request: GA-EP45-UD3 (without P, R or L) Intel RAID

[Dexter41]

Hello. I have a Gigabyte EP45-UD3 (rev 1.0) motherboard running a C2Q Q9400 overclocked to 4GHz (500x8). I am very happy with this board except for 2 things:
- It doesn't wake up from sleep (S1 or S3) when overclocked heavily (like I have it) and
- It doesn't support Intel RAID, only the Jmicron chip supports RAID and it kinda sucks.

The sleep issue I can live with, but I would love to know whether this mobo is Intel-RAID-capable through a BIOS mod. Is it? Could anyone please try to mod (or tell me how to mod) the latest non-beta bios (F9, located here http://www.gigabyte.com/products/product...=2920#bios ) to unlock the Intel RAID?

I would be extremely happy.
Thanks in advance.

RAID enabled (didn't change text from SATA AHCI Mode though)
RAID OROM 10.6.0 (11.0 is problematic with some external RAID cards and Intel stopped using it, so I also have)
JMicron 1.07.28

Untested

Thank you. I will test it as soon as i have some time to.

Well, this BIOS bricked my board. Maybe the southbridge present on my board isn't ICH10R but just ICH10... Anyway I fixed my board by googling a solution to force the MB to boot from the backup bios... Thanks anyway.

If you have any idea why this bios bricked the board, you can fix it and upload another version and I will test it. Now I know how to boot from backup, so no problem if it gets bricked again...

Hmm... I'm not sure. I didn't do anything out of the ordinary with this. I'll look at it again sometime soon and double check everything, but if that didn't work then I can't promise I'll be able to come up with something different...

Hi
I know this is an old topic however I confirm the proposed modded BIOS also bricked my own EP45-UD3 rev1.0 MB. Had to shorten pins 4-7 on the main BIOS chip to get out of this trap, none of the other well-known recommendations worked to make the board boot properly. Pins 5-6, 1-6, none worked as well.

So... I tested it 'just in case', as Intel states its ICH10R supports >2TB sata drives, but this requires an update to the manufacturer's BIOS with the Intel bits to support it.
I found no convenient up-to-date BIOS here for this MB, or on other forums. Anybody has a clue ? or some time to provide with an 'not-sit-recent-but-works' BIOS including Intel support for >2TB drives ?

Thanks !

The GA-EP45-UD3 (without P, R or L) MB has the ICH10 Southbridge, not the ICH10R version which supports Intel Raid. The best setup, if using the Intel SATA ports with a 3TB or greater HD, would be to first install a supporting OS in a 2047MB MBR partition since this MB does not support UEFI bios. Then set the remaining space to a GPT parittion as large as you like.

I made the following changes to the GA-EP45-UD3 rev 1.0 F10b bios downloaded from Gigabyte's website

ICHAAHCI - ICHAAHCI12
SATA2 chip - j3_10724.bin
8111C ethernet - rtegrom260.lom
NCPUCODE - updated to cover the latest LGA775 CPUs & LGA771 Xeons (using sticker and MB socket mod)

Hi,

The GA-EP45-UD3 (without P, R or L) MB has the ICH10 Southbridge, not the ICH10R version which supports Intel Raid.

I was mistaking due to CPU-Z reporting I have an ICH10R. I thought it was a BIOS-limited ICH10R version. However I never forced any EP45-UD3R BIOS, I guess it is a 'little bit' more complex

The best setup, if using the Intel SATA ports with a 3TB or greater HD, would be to first install a supporting OS in a 2047MB MBR partition since this MB does not support UEFI bios. Then set the remaining space to a GPT parittion as large as you like.

This is not my main HDD. So I was expecting it to work as expected as a DynamicDk+GPTPart, but it didn't, reporting 746.39GB instead of 2794.39GB.
I know it works when pre-formatting the drive on another system, but as this is an internal disk and I often change the partitionning of the 5 drives, this is quite annoying.

I made the following changes to the GA-EP45-UD3 rev 1.0 F10b bios downloaded from Gigabyte's website
ICHAAHCI - ICHAAHCI12
SATA2 chip - j3_10724.bin
8111C ethernet - rtegrom260.lom
NCPUCODE - updated to cover the latest LGA775 CPUs & LGA771 Xeons (using sticker and MB socket mod)

Just installed it, works like a charm, however I don' t 'see' any change from the SATA perspective. The drive still incorrectly reports its total size, while the already created GPT partition reports its 3TB size.

But I'd like to really thank you for trying ! Just for fun I O/Ced the Q6600 G0 to 3.6Ghz, pretty stable for now, with 1066MHz RAM on a 5/5/5/18 timing.

Let me know in case you feel something can be done for the SATA part.

Again, thanks !
cheers,
Sylvain.
