Anyone still running a ASUS p5q and a q9550?

[happy medium]

I just bought a q9550 chip that was supposed to do 4.0 with 1.26 volts.

I have it at 3.6 at 1.34 volts @ 60c load running prime.
Besides the fsb, cpu voltage and memory adjustments, I really don't know what the other settings are for.

I tried google and other peoples settings and I did get it to boot to windows @ 3.9 ,but with 1.4 volts. Prime crashed in seconds.

I tried it at 3.6 @ 1.32volts and it booted to windows but failed prime in 20 seconds or so. This tells me with a little less voltage its the cpu thats the problem . Correct?

Is there something I'm missing?


Can anyone help?

 

[Kenmitch]

Yep....See sig

I didn't have much fight going to 4ghz....was set it and forget it

I'm currently at work tho....I may be able to give you my settings tonight depending when my daughter goes to sleep.

What's your mem specs? To get 4ghz you need some good memory

Did you consider your power supply maybe not strong enough?

Overclocking results do very from board to board also.

P5Q vanilla?

You're going to run into FSB/NB GTL issues.

A lot of times for the P5Qs, once you hit around 425-450 FSB you have to get FSB & NB voltages + GTLs just right to get any further.

Try with a lower CPU multi to see this.

If you're running 7x450 & getting errors, i'd say that's not a CPU issue; that's a board instability...(assuming your RAM is up to the task).

 

[happy medium]

I have G-skill ddr2 1000, the memory was running at 900 or something like that with the divider.
It's a Asus p5q deluxe board.
I was thinking about the psu but I ran some Crysis with my gpu and cpu overclocked and it ran great. I thought it would stress the 12v rail the most.
But it could be shaky rails mabe? Mabe I have to overvolt to compinsate?

Yea when I run above 424 fsb it seems to start to flake out.wierd.
Mabe I should do a bios update?

If you could give me your settings that would be great Kenmitch.

Thanks guys for the help.

Oh I did try the 7.5 multy @ 450 fsb and it screwed up windows on startup.

Edit: if it was the board, why when I drop the voltage .002 just on the cpu does it crash @ 3.6? Thats why I thought it was the cpu.

Here's a post i made a while back on XS...going to repost it here.
All my settings are there.
Be aware it's highly unlikely my exact ones will work for you, but it'll give you something to look at anyway.
(Obviously you won't be doing the same CPU/RAM speeds; looks at the voltages more.)

Just want to offer some encouragement for people running 8 GB on this board.

It can be done, albeit sometimes a PITA.

This is with my new OCZ Platinums.

Notice how low i've kept the motherboard voltages?

You really do not need a ton of vFSB or vNB on this board.
It's very much a finesse mobo though.
Brute forcing by using higher voltages pretty much never works...believe me, i've tried.
If you spend time with it, get your vFSB & vNB & GTL perfect (and yes, they have to be perfect or you will get nowhere), it's not bad.

I actually sold my UD3P because i found for 8 GB, my P5Q-D was a more solid board, a lot less flakey.
For 2x2 GB, no question, UD3P is miles better.
But at least for me, my P5Q-D i much preferred for 8 GB.

I'll try these. ANd thanks
I just got a blue screen and reset after playing CSS for 2 hours @ 3.6.
Wierd.

This is what works for me at the moment.

I'm kinda waiting for my HD5850 to show up before I finish tweaking my system....In case it makes a diff

I've had my chip up to 4.14ghz so far....But think I'll just tweak her out at 4ghz as it'll be less work for me and just bragging rights anyways

I tried both sets of settings. As soon as I go above 425 fsb, it boots to windows very very slowly and never finishes.

I'm at a loss for idea's.
Its now sitting @ 3.6 stable with everything on default or auto except the ram voltage is at 2.1 and fsb is at 423.

What kinda vcore does it feed the chip on auto?

What bios version does your board have?

 

[happy medium]

1.32/34 on auto

The latest bios.

Just played a 2 hour marathon of Crysis Warhead without a problem.
I don't think it's the power supply.

 

[Kenmitch]

My board is running 2005 bios....Not sure if downgrading would help you out tho.

Hmm....If your comfortable with flashing bios and willing to try out a modified version I did read that some people did have good results from it. Guess it increases ram compatability

http://www.xtremesystems.org/forums/showpost.php?p=3898769&postcount=1945

I was gonna try it but decided if she's stable at 4ghz why bother.

Not sure who you bought the chip from but....You do trust them?

You could always run to best buy and pick up a corsair power supply and see if it helps....If not just return it

You have tried reseating the ram and doubling checking all your cables etc I'd assume

 

[happy medium]

I'm gonna need a new psu soon anyway for a video upgrade.
I might try that bios you linked. I don't think the board likes this odd ram speed I have.ddr2 1000. I noticed the 400 memory divider not working correctly. Its running at 1016 right now with the 333 divider.
Cpuz shows it as pc6400. I wish I had a stick of 1066 to test it.

Huh?

You realize the RAM ratio is calculated based on FSB speed, right?

And it's not 333 divider, it's 333 NB strap.

The ratio you are running is 5:6 or 1.2

FSB = 423
423 5:6 (1.2x) = 507.6 (DDR2-1015)

You should be sticking w/ 1:1 while you work on getting a higher FSB stable, unless you already know your RAM's max.

Set to 400 strap, & choose the lowest RAM speed (this would be DDR2-846 @ your current FSB.

Oh, & here's the XS thread on GTLs.

happy medium, i see in your signature that you run a 535 watt power supply. is that what you are trying to get 4 ghz with on the Q9550?

Do you think this is my problem?
Even though I can run a game like Crysis Warhead with both my cpu (3.6) and gpu gtx 260 overclocked with out a problem.

When I try to overclock 2 more fsb with prime it fails quickly.
I would think that running Crysis would stress my 12v line more then JUST prime with no gpu?

How many watts does a overclocked q9550 run 140 mabe? 12amps?
My gtx 260 underclocks itself in 2d. 75 watts idle?
2 harddrives and 2 dvd drives.

If not please educate me.:thumbsup:

And thanks for your help

 

[hclarkjr]

i would get at least a good, quality power supply in the 700-750 range so that you have some overhead. do some reading here on good power supply to choose http://www.jonnyguru.com/index.php

 

[Kenmitch]

I'm kinda leaning toward memory issue. Try to slow your memory down as suggested above and see if it helps.

 

[happy medium]

When I go over 423 bus ,I do use the 1:1 divider. The memory runs at high 800's.

I think I'm getting a Corsair tx850 for crossfire 5830's anyway.

Thanks for the Johnny link.

good choice on power supply :thumbsup:

n7, could it be a fsb hole like i had on my old UD3R P45 & Q9550?

in some UT3 Vipers DM right now btw

 

[happy medium]

I tried 450,475 fsb,just in case. At 3.9 it booted to windows but at 1.4 volts.

thanks again

Edit : something to add, I was playing CSS for about an hour,when I went to quit the program it bluescreened.
Starting to think its the memory.

 

[BTRY B 529th FA BN]

Make sure you have the latest bios first of all.

Now, if you have all dimm slots occupied it will be alot harder running high fsb for something like 4Ghz... my 4Ghz is done by 500fsb by an 8 multi. I am running 2x2 & DDR2 1000 so I don't have to worry about hitting a memory wall when trying to overclock; thus 500fsb is my max without overclocking the ram. My Q9550 is almost near the Intel vcore max. In bios it's at 1.375 but with vdroop it is a steady 1.34v and stable.

First I would drop your multi to 6 and run Memtest86 vX.XX to see if your ram is stable at 1:1 ratio. You'll need to burn Memtest to a disc and boot into it. So say if you have DDR 900 then 450fsb would be 1:1 and DDR 800 would be 400fsb at 1:1 and so on. This way you test to see if your memory isn't the problem. After about 3 100% passes in Memtest86 (you can do this longer but i'd do 3 at minimum) boot into windows at the same low multi of 6 and 1:1 ratio of your ram. Mine was 6mulit x 500fsb = 3Ghz in windows. This way I knew there wasn't so much pressure on the CPU and RAM there-by isolating the motherboards subsystem. This is where you test the NB. One of the best apps to test the MB subsystem (NB circuitry) is Prim95 Large FFTs.

A few settings I have:
**Clock Chip Control**
CPU Host Freq - 500fsb
PCI Express - 100

**DRAM Performance Control**
Performance Enhance - (I would keep yours at standard until you get a stable OC then play with this)
System Memory Multi - I am using 2.00D

>>> Standard Timing Control
Manually set these to the Memorys factory settings (mine are 5.5.5.15)

>>> CPU ***ALL OF YOURS IN THIS AREA MAY VARY FROM MINE***
Load-Line Calibration AKA LLC - Enabled
CPU Vcore - 1.37500v
CPU Termination 1.320v
CPU PLL - 1.650v

>>> MCH/ICH
MCH Core 1.400v

>>> DRAM
Dram Voltage - 2.080v (my max is 2.1v - try keeping it under the very max)

MANUALLY SET THOSE VOLTAGES AT STOCK FIRST then raise them accordingly. You've eliminated your memory by testing your memory's Max advertised rating so that's when stuff like Vcore, Termination, PLL, and MCH Core come into play. There is a .0500 difference between the Vcore and Termination so try to keep that difference at all times.
You will probably pass P95 Large FFTs at the lowest multi at your max 1:1 ratio and/or fsb.

So, when you start getting blue screens and or not booting into your OS that's when you slightly raise those settings. PLL & MCH (MCH is your NB) would be a good place to start then if you keep failing your boot or blue screen in P95 raise your Vcore but keep that Termination at a difference of .0500v

With that, you should keep testing to you reach your OC goal. Be careful not to overheat your chip beyond 70*c on the cores. 70*c is conservative but good advice.

You may also want to test your system stability with LinX - maybe 20 or 30 passes at the most memory you're allowed by the app. This will heat your system up tremendously so keep an eye on your core temps. I personally use Hardware Monitor which monitors your core temps and Northbridge temps as well as giving your voltage readings, fan speeds, etc..

If you have any more questions feel free to pm me. I pm'ed you as to not steal that thread's topic.

Have Fun and Good Luck!

Thanks Btry,

Its definitly the motherboard.

Settings:

Multy 6.0

fsb strap 400
Dram @ 849 (I have gskill 1000)

cpu voltage auto
All the rest auto

Passed large prime.

Went to 425 fsb, and windows had trouble loading, but did slowly.

I have some studying to do with these settings.

cpu GTL voltage reference (0/2)
cpu GTL voltage reference (1/3)
Cpu PLL voltage
FSB Termination Voltage
NB voltage
NB GTL voltage
sbridge voltage
pcie Sata voltage

I wish I knew the values of each on auto ,and which to raise and why.

Can you try a different FSB other than 425 at a 6x multiplier? Try out 440 or 450 or 460. Also can you post what your northbridge temperatures are? I know on my P5Q Deluxe that my system would crash if the northbridge got above 70c.

Also if your system isn't stable at 450mhz fsb with a 6x multiplier, try removing one stick of ram. Also try switching your ram sticks around to other slots.

What is your AI Clock Twister setting set at? Set it at Light while trying to determine a stable overclock for now.


This is definitely an awesome board though, I'd find it hard to believe yours would be so much worse than other people's. Here's a screen shot of mine running a 65nm quad core (it'll actually boot into windows at 500mhz).
