Re: UD3P and Q9550 Overclock Problems

All 4 cores at that temp? What are the idle temps and room temperature?

Re: UD3P and Q9550 Overclock Problems

I was going to attach all 4 graphs of the cpu temps but it looks like I can only do one attachment at a time? If not, a little guidance would be appreciated. Anyway, cpu 2, 3,and 4 run one or two degrees cooler. The room temp is a cool 65F and the case is a Lian Li P61 with all the fans running.

Oh ok cool ambiant makes sense

Re: UD3P and Q9550 Overclock Problems

Check posts by conners and acebmxer like the one acebmx linked.

The big core voltage difference will go if you enable llc ,load line calibration.
1.33 will be like 1.31 under load ,that kind of thing.

re: Cpu Vcore displayed voltage
It's normal with your mobo to see that the displayed voltage (at idle) will be 0.04 volts lower than the value set in your bios.

A snip from Conner's bios settings with the same mobo and cpu:

Conners q9550 @ 3.80GHz [8.5 x 450]
MB Intelligent Tweaker(M.I.T.)
Robust Graphics Booster ...............: Fast
CPU Clock Ratio ...........................: 8 X
Fine CPU Clock Ratio.....................: +0.5
CPU Frequency ...................: 3.8GHz<-- note much lower setting

See if setting a lower CPU Vcore is fully stable and if it eliminates the wake from sleep issue.
Stability testing needs to be run for at least 6 - 10 hours. A 24 hour test is even better.

Important note: When Conners went from 3.6 to 3.8GHz, he was smitten by the overclocking bug and didn't stop until his system was stable at 4.25GHz.
Who knows, he might even try for an even higher o/c.

Re: UD3P and Q9550 Overclock Problems

It ain't cpu-z or OCCT that is causing the wake up problem. I had this thing running at 4.7GHz for hours under load with no problems - even lowered the Vcore voltage to 1.26 and it kept running. Then I let it go to sleep and it would not wake up without me turning off the main power switch and then finally after several attempts by the MB it resumed Vista. I then increased the voltage to 1.3V and still had the problem. I lowered the FSB to 425 or 3.4GHz and everything worked like it should. It looks like at least one other person has this same issue. Any ideas on what I should change would be appreciated. I can make the problem occur anytime I so desire - just go beyond 3.4GHz!

Sorry ProfJim I posted before I read your post. I think I hit all your points by accident but I would just like to get to a system that runs quietly at 3.8GHz and will wake up like a good boy so Windows Home Server can do it's back up thing in the middle of the night.

Well this person has a completely different setup, not the same board anyway.
I do suspect it's has something to do with the BIOS, but I don't expect GIGABYTE to put much effort in it as it's not realy an overclockers board.
The reson I suspect BIOS is the difference between power on vcore and target vcore showed in ET6. It might however be just a glitch in ET6.

Re: UD3P and Q9550 Overclock Problems

If you add your bios version and mobo version to your signature, you'll make it much easier for us. Changing "UD3P" to EP45-UD3P will avoid confusion, as there are several UD3P motherboards in the Gigabyte lineup.

You should contact Gigabyte tech support directly and briefly describe that you're having sleep issues above xxxx frequencies. Your rev:1.6 mobo only has two bios versions, and they differ from the available versions for the rev:1.0 and rev:1.1 EP45-UD3P motherboards.

Re: UD3P and Q9550 Overclock Problems

Do you have any suggestions on the best way to get Gigabyte Tech Support. The last time I tried as soon as I said OC they went silent.

[profJim]

Re: UD3P and Q9550 Overclock Problems

You might have more luck if you can skirt the issue by stating that your system is completely stable when running your system at 3.6GHz but the wake from sleep function does not work, and you would like to know when they will have a bios fix to address this issue.
Maybe they'll be more responsive if you ask if you should RMA your motherboard.

I wish more forum members included their operating system version in their forum signature like you did. Add "rev:1.6" to your signature and I'll keep quiet :)
Let us know if tech support replies to your inquiry.

Re: UD3P and Q9550 Overclock Problems

For what it's worth - Gigabyte Tech Support says its a common problem with an overclocked Crossfire enabled board and an Nvidia Video card. Something about getting back in sinc when exiting sleep mode.
XFX says -
BRIAN 8/28/2009 6:04:13 PM] Hi, I`ve never heard of that before. Overclocking is not an exact science and some aspects may not work right when you are pushing components past certain points. If it is stable at 3.4GHz, then I would keep it there. If only sleep mode doesn`t work at 3.6GHz, then there really isn`t much that can be done since when you overclock anything, it is not guaranteed to work. Also, if you are not overclocking the card, then I really don`t think that this is going to be a video card issue. Thanks, Brian."
Can you believe it? I think I bought my last XFX card!

When I look at the three systems on this forum that have experienced this problem they all have Nvidia based video cards?!

That is normal, Power ON Vcore can be default or anything you have set in the Past. Target Vcore is what you currently have set in the BIOS. Same applies to the Freq tab

Here is mine so you can see it is normal



Basically you can ignore that left section as it is random and rarely correct, same applies to settings you see on the left in the BIOS, they are NOT Auto settings.

Re: UD3P and Q9550 Overclock Problems

HELP! I could not leave well enough alone and did a CMOS clear. I thought I would start fresh and maybe... clear up any problem I might have created along the way. Wrong. When I rebooted with the settings that I thought were stable prior to the CMOS clearing the system would only run for a few minutes before getting a CPU failure (different core each time I tried). In fact, it would not even boot at 3.7MHz. So here are my latest settings. The system runs for hours under OCCT 3.1. at 3.6GHZ. The system idles at 1.33V and runs under load at 1.28-1.30V?! The cpu temps never get above 50C but I'm cheating since the room temp is 65F and the cover is off the case. Anyway, the system will still not boot at 3.7MHz. Does that mean I got a lousy system and 3.6MHz is as good as it gets or is there something I should look at changing? I have tried upping the Vcore voltage to 1.38750V, CPU Termination to 1.32V, MCHCore to 1.32V and DRAM to 2.06V but it does not seem to make a difference. Any suggestions would be appreciated.

About the VID comment - what I meant was the second Gigabyte Tech did not seem to know that the VID is burned into the CPU by Intel and that is what the default Vcore voltage was in the BIOS. So I guess I was mistaken when for some reason I thought it changed from 1.25V to the 1.28750V based on something I did.

Re: UD3P and Q9550 Overclock Problems

After your CMOS clear, did you load Optimized settings before applying your bios changes?
Did you restore your bios settings from a saved bios profile?

Go into your bios and confirm that following are the same as your bios template:
CPU Clock Drive = 800mV
PCI Express Clock Drive = 900mV

note: Some of your voltages are too high for 3.6GHz and 450MHz
