!!! Issues with UD3P !!!

[northnyc]

Hello everyone,
I recently buit the configuration from my signature and ever since have been experiencing troubles with stability.
At first I used the Corsair XMS 2x2gb 1066 ram but it was faulty so I got the Crucial wich is with micron double sided chips but ddr2 800.
At current clock levels 445x9 vcore 1.37, vmch 1.32, vddr 2.02 and with loose timings I was able to run Prime95 twice for 9 hours error free.
Even though the pc is prime stable it gets random freezes and a blue screen appears saying something like dumping memory and a countdown starts or just freezes.
Any ideas what might cause that? I am almost possitive that it is something in the BIOS.
Here is what my BIOS settings look like:

MB Intelligent Tweaker(M.I.T.)
Robust Graphics Booster ...............: AUTO
CPUSupport....................: [Disabled]
x C4/C4E State Support..................: [Disabled]
CPU Thermal Monitor 2(TM2) ...........: [Enabled]
CPU EIST Function.........................: [Disabled]
Virtualization Technology................: ???



CPU: E8400 (E0) + Xigmatek S1284EE + Arctic Silver 5
PSU: CORSAIR TW750W

Thanks in advance to all!

Re: !!! Issues with UD3P !!!

Max out something.
Since your on 800mhz memory now that should be the easiest to test .
See how far it will go with lowered cpu multiplier and raised memory multiplier if needed.
See how far it will clock with its 800mhz epp settings(if it has them) entered in bios,then see how far it will go on standard 1066 timings and at what voltage,that kind of thing.

Once you have an idea on those settings(without tweaking mch and cpu voltage much)I find it helps a lot.
NB temps seem to be able to get higher fast,if you dont have a fan blowing on the nb heatsink,good to have it blowing on the memory too,mho.
My NB fan is controlled by the sys temp sensor(im not sure where that is),but i believe its closer to the southbridge.Im using a seperate nb temp sensor.

For testing I like occt configured to use a utility like speedfan or everset because it shows exact temps and speeds at any time there is a failure,with graphs over time.

For example I was happy enough with 1.4 entered in mch v and it ran for hours on prime ,I locked up once on WoW,n got a failure on occt about 20 min into a test suite a few times.
I checked the graphs and voltage variations (on all outputs 3v/5v too were high) so 1.42 seemed to cure that.
Thats v individual tho and Im not saying that banging in some mch will cure any probs.

I have a 490 fsb v safe,comparatively,bios setting saved : it needs lower voltages V especially for memory but it has a lot of settings on auto.pll/cpu ref/ etc took me a long time to work out for 500fsb

Oh yeh get some setting stable on testing like 5-10mhz fsb/cpu ref higher than what you want to run 24/7stable .So if you want to run 500mhz fsb(2000) with a x8 cpu multiplier(4000 mhz) 24/7 get 505-510 mhz stable under testing that way you know you wont be right on the edge.

Re: !!! Issues with UD3P !!!

Try 2.0D for the system memory multiplier.
Run Prime in small FFTs mode and see how fast/whether you get errors there. If it fails faster in blend then it's usually a RAM issue while a failure in small FFTs is usually CPU related.

Re: !!! Issues with UD3P !!!

Your problem is probably due to some incorrect bios settings.
I see several possible bios settings that might be causing your problems, but we need more info before we can make specific recommendations.

Create a signature that lists your system's components.
Add a link to your ram's full specifications.
We will be able to help you after you've posted with this info.

Re: !!! Issues with UD3P !!!

I cant find the signature field in the settings so here it is:

Gigabyte UD3P rev. 1.0 BIOS F5 @ 1.32V | Intel C2D E8400 E0 @ 4.0Ghz (445x9 @ 1.37V) | Xigmatek 1284EE with I7753 Bracket + AS5 |
Crucial Ballistix 2x2GB DDR2 800 @ 2.0V | Seagate 500GB 7200.11 32MB cache | BFG 9800 GTX | Corsair TX 750W |

and this is my memory: BL2KIT25664AA80A - 4GB kit (2GBx2), Ballistix 240-pin DIMM , DDR2 PC2-6400 from Crucial.com

Re: !!! Issues with UD3P !!!

Your F5 bios is old and might be holding you back. F9 is the current latest supported version.
DO NOT USE @BIOS TO FLASH YOUR MOBO. Q-Flash in the bios is the safest way to flash.
Read the Bios Flashing Guide before you flash your mobo.

Forget 4.0 GHz for now. Drop down to 3.8 - 3.9 GHz for initial stability testing.

Change the following and test for stability. Once stable at your desired goals, additional memory tweaks will provide more performance.

CPU Host Frequency (Mhz) ............: 445Mhz <-- change to 440 for now
System Memory Multiplier ..............: 2.00B <-- change to 2.00D for now (once your system is fully stable, try 2.00B for better memory performance)
Advanced Timing Control
tRRD...........................................4 <-- set to AUTO for now
tWTR.........................................20 <-- set to AUTO for now
tWR...........................................15 <-- set to AUTO for now
tRFC..........................................58 <-- set to 52 for now
tRTP............................................8 <-- set to AUTO for now

Channel A Timing Settings ............... [Press ENTER] <-- to set Static tRead Value
Static tRead Value.........................: ??? <-- set to 8 for now (9 might be needed when using 2.00D memory multiplier)

Channel B Timing Settings ............... [Press ENTER] <-- to set Static tRead Value
Static tRead Value.........................: ??? <-- set to 8 for now (9 might be needed when using 2.00D memory multiplier)

Channel A Driving Settings ............... [Press ENTER] <-- to set Drive Strength <-- set to 1066
Channel B Driving Settings ............... [Press ENTER] <-- to set Drive Strength <-- set to 1066

CPU Vcore ....................: 1.40 (1.37 in OS) <-- 1.35 - 1.38 will probably work
CPU Termination .............:1.22 <-- 1.24 - 1.30 might help stability

MCH Core ......................:1.32 <-- too much hurts stability, for 2.2GB PC2-6400 memory, try 1.15 - 1.26 (start low and go higher if necessary)

Advanced Bios Features
Virtualization Technology ..: ??? <-- set to Disabled unless you're running VMware

Integrated Peripherals
Legacy USB Storage Detect ......: [Enabled] <-- set to Disabled while overclocking (must be Enabled to boot from a USB drive)

Primary memory timings = 5-5-5-15 should work fine. It's OK if you want to leave them at your current (looser) settings.

On your next post, include a screen shot with:
Memset: Include the SPD and ">>" tabs.
Cpu-z: main screen
EasyTune: Advanced tab --> Voltages panel (the screen that shows multiple voltage settings in the bios)

To add your hardware list in your signature, press USER CP in the upper left corner of the web page. Under Settings & Options on the left, select Edit Signature. Save your settings when you're done.

For better or for worse, post your full bios test setup in your next post.

Have fun!!

Re: !!! Issues with UD3P !!!

profjim I just updated the BIOS with the steps from the quide to F9.
I entered the settings you suggested.
I ran prime95 small FTTs for 30min without problems (i know its not enough).
Here is a screenshot of the settings:

Re: !!! Issues with UD3P !!!

CPU PLL is way too high.
It looks like you left it on AUTO.
Which makes sense, I omitted the following setting:

CPU PLL .........1.500V.............: [Auto] <-- set to 1.57

Change this setting ASAP.

Samll FFTs primarily test the cpu, not ram. Blend Testing works cpu and ram.

IBT (Intel BurnTest) is excellent for a short but thorough stability test.
Just be sure to watch your temps closely.

Looking good so far!!

[northnyc]

Re: !!! Issues with UD3P !!!

changed PLL last night and then ran Prime95 blend test for 8 hours error free.

[profJim]

Re: !!! Issues with UD3P !!!

So far, so good!!
In your original post, you said:

I was able to run Prime95 twice for 9 hours error free.
Even though the pc is prime stable it gets random freezes and a blue screen
appears saying something like dumping memory and a countdown starts or
just freezes.

Any good news on overall stability?

[northnyc]

Re: !!! Issues with UD3P !!!

Even with the old setup it gave me blue screens and froze rarely, probably twice a month but still annoyed me. Now for just a day its fine, I haven’t had any troubles.

Re: !!! Issues with UD3P !!!

tried 450x9 with same settings from above, same voltage as well and couldn`t power on.
Will need either more voltage or better memory.
what are the following:

No execute memory protect?
CPU Thermal monitor (TM2)?
PCI Express seto to auto or 100?
load line calibration?

[QUOTE=northnyc;295955]tried 450x9 with same settings from above, same voltage as well and couldn`t power on.

what are the following:

No execute memory protect? buffer attacks etc leave enabled
CPU Thermal monitor (TM2)? cpu throttle back protect eanble
PCI Express seto to auto or 100? 100
load line calibration? reduces v drop on cpu volts when OC. though intel spec allows for v droop.

Re: !!! Issues with UD3P !!!

If you still need help here post me your full settings that fail, and let me know how they fail and I can offer you some advice.

You likely do need more Vtt (Termination) and possibly more MCH voltage, but I would need to know your memory multi choice that you tried above for 450 to advise

What voltage amount does that 2.02 Memory setting give you actual? You can check in PC Health page or with Everest in the sensor section
