** Official ** Gigabyte UD3 P45 Series -- EP45-UD3 / EP45-UD3R / EP45-UD3P

[NoGuru]

thank you for your help (and quick reply) NoGuru, bumped up the term and pll still a no go, i guess she just doesn't want to go any higher

If you play with your skews and ref's, you might be able to squeeze a little more, but that is already an impressive clock.

I'm still on BIOS F10e. I have forgotten how to get this one off the board, since it locks in.

Can someone reiterate on how to get it to flash?

[vailr]

If anyone is interested, there have been recently released beta versions of "Gigabyte Mac Edition BIOS" for several Gigabyte P45 boards.

The author would probably like feedback about any compatibility problems, as far as running standard non-OSX operating systems, such as Windows, Ubuntu, etc. while using these modified bios.

[radaja]

so if you flash to one of these bios's you can install mac?

OSX has already been installed while using the official Gigabyte bios, but doing that requires some workarounds. The forums at insanelymac.com are one source for further info. The eventual goal is to be able to boot the retail Snow Leopard DVD and install directly. All the while maintaining Windows, Ubuntu, etc. dual-boot capability.

Hello

First excuse my english.

My PC configuration is

CPU = Q9550 E0 vid 1.2125 in core temp
Cooler: Noctua NH-U12P
Motherboard = Gigabyte EP45-UD3-R rev.1.0
BIOS Version = F12
Ram = OCZ DDR2 PC2-9200 Flex II 4GB Series
1150MHzDDR2
CL 5-5-5-18
Available in 4GB (2x2048) Dual Channel Kits
Unbuffered
OCZ DDR2 PC2-9200 Flex II 4GB Series *EOL OCZ Technology

After Upgrade my bios to F12 I have reached a OC of 3.61 GHz (i Think that it is stable) I passed 3 hours of orthos with the hotest core at 55 Cº and 20 cicles of intelburn test with the hotest core at 61 Cº.

However I think my setting could be optized to reach better voltages and temperatures and setting better my memories for 3.62 GHZ.

NOTE: I have reached 3.8 GHZ (448x8.5) with the same setting changing only CPU Vcore to 1.2125 value and now i´m testing (intelburn 20 cicles passed and max temp 63 Cº in the hotest core) <now testing with orthos.

Well my setting for 3.61 GHz are

Thank for your help

That's a good start. To try and push your FSB even higher, change your CPU reference to 0.775 and MCH reference to 0.80 while you have termination set to 1.2v, then move it back up to 1.28 (CPU and MCH references will both move up as well). This works well for a lot of people with q9xxx on these boards and I think you could push as far as 470-500fsb while still keeping low temperatures (and maybe even overclock your memory if you get near 500 ). Good luck.

Before i´m tryng 3,8 with lower CPU VCore

A question. I´m confused with

I set CPU Termination…..1.200V*.......: 1.280v and i set this settings as AUTO but is it correct (OK)? Or with AUTO i have too high voltages?

Thanks

What is the latest available BIOS for the Rev 1.0 of the EP45-UD3P please?

For some reason my PC can no longer boot from my OCZ Vertex 30g when AHCI mode or RAID is enable in the BIOS, the machine just hangs at the Intel AHCI BIOS screen.

If I switch back to standard IDE everything is fine.

The machinie will boot using AHCI / RAid if the OCZ Vertex is not plugged in, I have been able to create a RAID array with two disk in the machine.

Everything was working fine than for what ever reason it stopped.

I have tried all the obvious things, reset BIOS, flash BIOS etc but I can't seem to fix the problem.

Any ideas?

1. Set CPU termination to 1.2v
2. Set CPU reference to 0.775, and MCH reference to 0.80
3. set CPU termination to 1.28v (and CPU and MCH reference will change - this is ok)

From here you might be able to get some higher FSB. I hope this is easy to understand now

@Slinwagh - there's a registry edit you can do to enable AHCI, it was posted by bluestang the other day:

A stupid question.

These voltage are lower or higher than I Set CPU reference to 0.760, and MCH reference to 0.90 (with CPU Termination at 1.280v)

I bag your pardon if question is stupid.

And MCH/DRAM Ref.…......0.900V?

Thanks

Hey guys just a heads up that my golden Q9650 is up for sale:

[radaja]

everytime i was looking for a golden Q9650,in the back of my head i always said
"i wish Jor would sell his to me" and now i've just went back to i7
and now for a little crystal ball action.... someone is going to be very happy soon

Can someone tell me which MOSFET water block to get for my GA-EP45-UD3P

Bought Jor3's chip. Thanks JoR3!

Bought Jor3's chip. Thanks JoR3!

And it went to a great home! I'm sure it will shine in your hands

So does this mean your selling the 9550, if so whats the batch and vid again?

Yes, the VID is 1.1750 and Batch is L944B663

NoGuru,thats awesome that you got it.be sure to post up your results

I see you have found yourself a nice batch 920 How's it clocking?

[MrDucky]

man if i had other cooling then a Z600 i could get to 4.5 to maybe :O cause im now on 4.25 with 1.264 volts but my cpu already hits 65C and my chip is Such a low vid 1.1375. but i dont have money for new cooling :X good to hear the CPU has a new Great home

[NoGuru]

NoGuru,thats awesome that you got it.be sure to post up your results

I will, though don't expect them to be as good as Jor3's.
I do all my clocks on air, might have to change that this year.

That's the whole kit, you can get blocks seperately
