Hi, I was planing to get a Q9550 as an upgrade to my E6600, and I was concerned that the Quad might not work with my motherboard, since I read on some sites that it might not work, is that true?

Or may I use the Q9550 with my current motherboard?

Greatly appreciate any and all information.

Thank You.

well sory to say u mobo mite not support the q9550 bcos of the FSB...but it can support the q6600....Go with tat...

thx for the info, just went threw asus's forum, looks like ppl have issues with it, and asus basically lies about support for it with the bios update, i was hoping to get the Q9550, as my last cpu before building a new system with the i7 in about 1.5 yeas from now.
the q6600 doesnt look to be much of an upgrade for the money ...sam clock, only 2 more cores...

yeah ....mayb if u could live with the E6600 for 1.5 yrs then its fine....but i feel that the if the q6600 can overclock so welll mayb u could try ur luck wit ur E6600...overclock it (if u motherboard allows which i doubt cos of the chipset..)but still give it a try ...
so mayb a 3GHz E6600 could stand a chance for those 1.5yrs...

Very good plan. I've had X1900, E6600 & 2GB DDR2-PC6400 FOR 2.5 YEARS. All ways runing at 3GHz, it's still a fast machine. A month ago I upgraded to a X4870, Q9550 & 4GB DDR2-PC8400. With the latest bios, she perrs along at 3.2 GHz. Just like yourself, I'll upgrade in 1.5 years. Thats one hell of a good life span for a P5W DH Deluxe, and it will still be a relavently fast machine then.
I gave it fast hard drives as well, 74GB 10,000 rpm, 2x 320Gb Raid 0, 320Gb, 1TB, 500GB internal back up, 500GB external back up

I used to own that motherboard. Solid performance and features, but I sold it due to it sticking on the BIOS load screen for about 40 seconds. It was beyond frustrating.

it works for me...

I got my new Q9550 processor today
and it works fine with the motherboard

asus p5w dh deluxe

I have all the latest BIOS and other ASUS related motherboard downloads installed prior to... installing the new chip

winXP initially ran a very fast check disk on the 1st start-up with the Q9550,
but after that no problems

The Q9550 has a multiplier of 8.5. According to Asus (and my P5W DH Deluxe), they don't support .5 multipliers. What multiplier are you using?
September 15, 2009 11:32:04 PM

I also meant to say in my post above that I was running winXP 32bit and a BIOS v.2801

the v2801 BIOS would not start my computer with windows 7 7600.xxxxx etc... 64bit

It just kept rebooting and would not bring the windows program up, so I changed drives on start up to winXp, then downloaded and installed ASUS BIOS v2901, which can handle both 32bit & 64bit O/S's

then after I installed v2901 I changed my drives back to my win7 64bit and it started right up & operates fine

----

Note: I've been gradually buying some new hardware items (month to month) and updating my current computer to an updated: Win7 Quad Core 2, 775 system (I'm still waiting on the new ATI/AMD video cards that are coming out in october after the win7 final release)

They just came out with a card (not yet released) that will handle 7 HD monitors... all from 1 video card... WOW!

----

Not to sure about the multiplier... where would I check that?

I'm going to buy a new motherboard in a week or 2 and redo my win7 64bit system to run on that with the Q9550

GIGABYTE GA-EP45-UD3P LGA 775 Intel P45 ATX Intel Motherboard

Then I will revert back to another computer build using my winXP 32bit O/S, my older Intel E6300 chip and this ASUS P5W DH Deluxe.

and switch between O/S systems by using a quick 5.25 quick change-out drive BAYS...

and then build another server system using the ASUS & the E6300 chip

You can see the multiplier in the BIOS and in CPU-Z. I'm positive your Q9550 isn't running at full speed. You'll like the GIGABYTE GA-EP45-UD3P.

That's rather interesting. It looks like a multiplier of 8.5 is possible at auto settings. In Advanced Settings, CPU Configuration, can you see that the current ratio is 8.5?

Here's another picture:

I set the bios setting back to default after installing the new cpu & didn't make any adjustment to them, so here's what they look like in... Advanced Settings, CPU Configuration

That answers my question. As you can see, the max ratio and actual value are 8, not 8.5 as would be expected when using that CPU. You can also see that the L2 and L3 cache are displayed as 0 KB (not an issue). I would also expect VT not to work with that combination, therefore you couldn't use it to run Hyper-V.

Thanks very much for the picture.

Hi

I try to get my ASUS P5w DH to work with my new Intel Q9550 CPU,
I have upgraded to the latest BIOS 2901,

I am using the CPU setings mentioned here, but,


- The system can boot into bios, and I can load for instance Win XP installer, or Linux installer,
I can leave the system in the menu for 1 hour ( to check for temperature power or other issues),
but as soon as I try to install or run the WIN XP installed on my hard drive the MB turn off power, and system restart.

Any ideas?
I use a geforce 7300 PCI express video, I have 1X 1GB RAM.

The system probably crashes and reboots. If it powered off, it shouln't power on again by itself. Did you test the memory and what is the CPU idle temperature?

What memory and memory settings are you using with this?

I recently installed a Q9550 on my P5W DH, but couldn't boot into Windows 7 (64) until I dropped the bus speed to 266 (recommended on another site). But, I didn't play with my memory settings at all beforing dropping this.

My memory is DDR2-6400, but according to CPU-Z, it's running at 333 currently.

Good day all.
I too followed down this path when, on cyber Mon this year, Tiger Direct briefly advertised the Q9550 for $209. Hot damn. I had been wanting to upgrade to a Quad Core and this was opportunity knocking prominently.
You CAN run the Q9550 on the P5W DH Deluxe (I’m using BIOS 3001). However the P5WDHD’s 1033 FSB and lack of fractional multiplier support does not permit you to fully exploit OC’ing the Q9550.
The native FSB speed of the P5WDHD is 1033 MHz. The newer BIOS seems to be designed to handle the situation as best it can. My P5DDHD, running in AUTO, sets 354.28 x 8.0 to achieve the 2.83 GHz native speed of the Q9550; effective FSB of 1417.13. But this doesn’t leave you much room for further OC’ing since you’re already well above the native FSB of the P5WDHD. Too bad. I ran my E6600 – which this board is exceptionally well suited for – at 3 GHz on air, rock solid.
On the up side, there IS a significant performance boost over the E6600. The quad cores kick in extra horsepower. The system is stable.
I’ll be moving on to manually tweaking to up the speed. I haven’t had much chance to experiment yet. I’d be interested in what other folks have been able to achieve. But this isn’t the best MOBO/processor combo.

Hi All,

I have been working hard to get my P5W DH Deluxe ready and stable for my new Q9550 and RAM and this thread definitely helped me but I'd like to tell you what I did.

Here are the steps I took to get it working.

- Install latest BIOS from Asus.
- Unplug system and remove old CPU, remove all memory and remove the battery from the motherboard. Wait a minute or 2.
- Add your new CPU with great Thermal SIlver Arctic paste and a decent CPU fan (I personality didn't use the stock Intel one cause they shipped a defect although it works just fine)
- Add one chip in the slot closest to the CPU
- Turn the PC on, make sure you get BIOS to post and go in BIOS.
- Set clock or any other defaults like boot order, etc
- Under Chipset Configuration, enable system for 64 OSes. (3rd option down)
- Under JumperFree Configuration, change to Manual
- Increase MCH (NorthBridge) voltage from Auto to 1.55V min
- Make sure the memory voltage match your component, it should by default.
- Increase CPU Clock from 333 to 366 -> +/- 10% overclock for the CPU
- Make sure the RAM Speed is lower than what your RAM can take. I had PC6400 capable memory chips but the system is stable at PC5700 with 4 chips... There may be chips out there that are better quality but people are right that 4 chips is hard to setup on this MOBO.
- When I get more time, I'll try to squeeze in a bit more power out of there. I tried to run at 400 but system became very unstable...
- Install Asus PC Probe II
- Install Prime95 and run LONG stress test on your system to make sure it's stable and temps are fine. From my reading, Mobo should get about 45C and CPU should not be allowed to hit more than 70C under continuous heavy load.

You can run Windows Server 2008 x64, but will Hyper-V work? According to Asus, VT is not supported when installing that CPU.

I just bought the Q9550 for my P5W DH Deluxe not realizing the issues people were having with that configuration. It's been 1 1/2 years since your post, what has your experience been since this set up? I get the blue screen of death when trying to boot into Windows 7 64 bit after installing the new chip.
