failing Orthos stress test

[rappy]

With the help of a member on this site I adjusted my P5B Deluxe to a moderate OC. The system booted up with out a hitch. I ran Orthos "Small FFTs " for a little over an hour (no errors). I run the "Large, In-place FFTs" test and it fails less then a minute, as well as the "Blend-stress CPU and RAM" test. I am not sure what I have done wrong? I am VERY much a newbe at this so I will list some data:

CPU-Z
CPU
Core Speed -3200 MHz +/- a few MHz
Multiplier - X8.0
Bus Speed - 400.0 MHz
Rated FSB - 1600.0 MHz +/- a few MHz
Memory
Channels # - SIngle
Size - 2048 MBytes
Frequency - 400.0 MHz
FSB: DRAM 1:1
Cas# Latency - 5.0 clocks
RAS# to CAS# Delay
RAS# Precharge - 5 clocks
Cycle TIme (tras) 12 clocks

This is what is in the BIOS

Jumper free Config: AI Tuning (Manual)**CPU Frequency (400)**DRAM Frequency (DDR-800MHz)**PCI Express Frequency (100)**PCI Clock Synchronization Mode (33.3MHz)**Spread Spectrum (Disables)**Memory Voltage (2.10V)**CPU Vcore Voltage (1.4000V)** FSB Termination Voltage (1.300V)** NB Vcore (Auto)** SB Vcore -SATA,PCIE- (AUTO)** ICH Chipset Voltage (AUTO) I am not sure if I have this setting correct?

Under CPU Configuration - Everything DISABLED, besides VANDERPOOL TECHNOLOGY (Enabled)

Under NB Chipset Features:
Memory Remap Feature (Disabled)**Configure DRAM Timing by SPD (Disabled)**DRAM CAS# Laency (5)**DRAM RAS# to CAS# Delay (5 DRAM Clocks)**DRAM RAS# Precharge (5 DRAM Clocks)**DRAM RAS# Activate to Precha (12 DRAM CLocks)** DRAM Write Recovery Time (6 DRAM Clocks)**DRAM TRRD (10)**Rank Write to Read Delay(10)**Read to Precharge Delay (10)** Write to Precharge Delay (10)** Static Read Control (Auto)

Any help/advice would be greatly appreciated.

You're running single channel which may cause a few problems. The proper configuration is to match the slot colors with your memory. Put both sticks into the Yellow slots and that will run dual channel. See what happens.

 

[Accord99]

Try disabling Static Read Control. I had similar problems with Prime95 until I disabled that setting.

 

[MADMAX23]

First of all, install your Ram dimms in the yellow coloured slots...right? Then give the NB: 1.45v, disable the static read control and give your Ram memory 2.15v.

Now try these conservative/relaxed settings for your RAM memory ok?
Here they are: (Starting from top to bottom)

5-5-5-18 (or 15)-6-42 (or 35)- 10-10-10-10

If ORTHOS keeps failing, shut down your Pc and unplug the power cord from the power supply, remove one Ram stick, boot and test Orthos, if it fails, do the same, turn off your pc, remove that stick and put in the other one, boot and test...if ORTHOS keeps failing...then you should up the FSBv to 1.40v and maybe the Vcore too a little....every system has its tweaks....

Take your time, be patient, the worst case would be that your Ram memory is not working properly, I mean, is defective...in that case RMA it, but first TEST...if you need to clear all doubts, up all voltages to Max values except Vcore, set it at 1.55v in Bios. You can give your Ram 2.3v for testing, don't worry, that won't hurt it....except for a 24/7 overclock...you know what I mean...

Hope this helps....Good luck!

Well just got a chance to install the DIMMs properly, disabled the "static Read Controll" and set the NB Vcore to 1.45. Ran the blended test and this time it errored out at about 4 minutes (rather then less the one minute). I guess that is a step in the right direction? I will contine to adjust.

[rappy]

Well after spending the last few hours messing around with settings, it doesnt look like I got to far. The best I can get Orhtos blended test to run is between 3 to 6 minutes with memory Voltage @ 2.15 (or Auto)**CPU Voltage 1.4**FSB termination Voltage 1.3** NB 1.45 and memory set at (top to bottom) 5-5-5-12-6-42-10-10-10-10** Static Read Control disabled. I also followed (as much as I could since I am still much a noob) MADMAX23's settings, and removed both sticks and tested (each time failed) and I also bumped up all the voltages to test. That failed as well. So I am lost???? Any other ideas or settings would greatly be appreciated.

You're on the right track.

I am not sure the RAM is the issue though; it shouldn't be anyway.

Could you try 8x401, not 8x400, with the settings you just mentioned?

Also, you may very well need more vcore. 1.4V in bios is only around 1.35V in Windows, which is basically max stock.

If jumping to 401+ & raising CPU vcore doesn't work, i'd try upping all the voltages (FSB/NB/SB/ICH) one step & NB two steps.

 

[rappy]

I think I got it.....well at least Orthos ran OK for 30 minutes (will test for a few hours latter in the evening). Her are my current settings:

CPU Freq(400)**DRAM Frew(800)**PCI Express(100)**PCI Clock(33.3)**Spread Spectrum(off)**Memory volt.(Auto)**CPU Vcore(1.4125v)**FSB Term.(1.4v)**NB Core(1.65v)**SB Core(auto)**ICH Chipset(auto).

RAM memory is- 5*5*5*12*6*42*10*10*10*10

Now, IF i want to bump it up a bit more , what settings should I bump up as well? Vcore and FSB? Or should I keep it at this level since I still want/need this to be a safe OC

Rappy

 

[rappy]

Ok...So I got it to 51 minutes then failed. Now what????

Rappy

 

[RandomUser]

My core system is nearly identical to yours (ASUS P5B, E6400 and 2Gig of Corsair XMS2 PC-6400 RAM) though I'm also a semi-newbie.

You haven't mentioned any temperatures yet. What are your CPU and motherboard temps during these tests?

As long as they are <55-60c under full load, you can bump up vcore one notch at a time to see if that eliminates the errors. I've been told that keeping temperatures under control is more important than the exact voltage that corresponds to them.

Different CPUs are going to require different voltages to achieve the same overclock without errors (I got lucky, and my CPU overclocks to 3200 at only 1.325V, but others have needed 1.4-1.5V on identical setups).

I'd also suggest keeping memory at 2.0 or 2.1 instead of auto, though I suspect that it is your CPU that is having issues, not your memory.

 

[rappy]

ok...so now my noob-ness comes out. I cant figgure out why the clock speed now shows 2568 MHz??? My current settings are:

AI Tuning(Manual)**CPU Freq(400)**DRAM(DDR 800)**PCIExpress (100)**PCI Clock(33.3)**Spread Spectrum(Disabled)**Memory volt.(2.10)**CPU Core(1.4)**FSB(1.3)**NB Core(1.45)**SB Core(AUto)**ICH(Auto)

ugh.....???

Rappy

 

[rappy]

With a bit of help I was able to get it back up to 3.2 GHz, but I still cant get past the blended Orthos test (approx 50 minutes) I have no clue what else to do. The best I can do is with 400 (CPU) freq - DRAM Freq @ 800 - 2.1 Memory voltage - 1.4 CPU Voltage - 1.3 FSB - 1.45 NB Vcore. I have the DRAM set at 5-5-5-12. I have been changing mostly the memory voltage and FSB voltage, but each time I do, I only get 2 to 5 minutes in Orthos. Could it have anything to do with my PSU?????Any other suggestions would greatly be appreciated.

Your memory is failing because you've set it to 5-5-5-12.......

Give this last number a value of 15 or higher, until 18, you'll see more stability, I promise.

"5-5-5-18 (or 15)-6-42 (or 35)- 10-10-10-10"

Also, you do not need to give the NB 1.65v....with 1.45v it should be enough, but for testing, leave it at 1.65v for now, once you find your system is stable, try lowering the NBv to 1.45 and test again.

Also you can set the Cpu v to 1.5v in Bios, that would discard it from failure....

Good luck!

Bump, sorry, Internet collapsed....

The Corsair XMS2 6400 is rated at 5-5-5-12 so it should work.

Like a broken record - I still cant get over the 1 hour hump @ 3.2 GHz. BUT there is some good news. Lowering the CPU freq to 375 (3000MHz) and all other settings the same (including memory) I am currently running the blended Orthos test at 1 hour 20 mintes. What does that mean??? Not that I need 3.2 GHz, but now it has become personal between the computer and me The sad thing is that the computer is winning!

There are a few issues with the Orthos beta and Core 2 Duo processors. The key question is will your system when overclocked run the applications you use everyday? If you had made it over an hour then it appears to me that heat is playing an issue with either your CPU or RAM. Also, on the P965 boards any setting from 365 to 400FSB is overclocking your MCH and will cause additional stress on the system. Try 401 FSB, memory at 1:1, MCH at 1.5+, memory at 2.2V 5-5-5-12 (lower it once you get it dialed in), CPU at 1.425V, PCI-E at 103, PCI fixed, FSB at 1.3V, and try Orthos again. I have witnessed plenty of Orthos stable Conroe systems that will refuse to run 3DMark06 along with Q4/BF2 at the same settings and vice versa.

 

[rappy]

Thanks Gary. I am at 2 hours currently. I will let it run a bit more and try some of the settings you suggested. Heat?? I have wondered if my Freezer pro would bo ok, or should I move up a step in cooling?? Right now, Core Temp shows about 61c to 63c, while Asus is showing the CPU temp at 56c and sytem at 40c. ps - what is MCH?

Thanks,

Rappy

MCH is the Memory Controller Hub or the Northbridge as it is more commonly called. Are you using AS5 on the Freezer Pro? The Freezer Pro is a good cooler, not one I would use for upper end overclocking but for mid-range clocks it should be fine. Also, Asus temp reports are usually high, yours seems to be okay considering the voltages. Another area that will help is removing the cheap pad material on the MCH and replacing it with AS5, usually drop the temps about 5C.

 

[rappy]

Yup - used AS5 for the CPU. So I should remove the passive heat sink(i think thats what its called) on the NB, add AS5 then reinstall it??? Ir maybe replace it?

By the way, I got just over 2 hours last night before it crashed (best timeing yet) with 375 as the CPU Freq. Again, I am truely lost on what I need to concentrate on to get this thing stable.

Rappy

 

[MADMAX23]

Did you try to run Orthos with your Bios at default settings before overclocking? I mean, test if your system (CPU and Ram mainly) is Orthos stable at default CPU and Ram speeds, timings and voltages. If you don´t know them set everything to AUTO and the FSB Bus speed to 266.

Once your system passes 6 hours (at least) of ORTHOS Blend test, you can overclock....if it does not pass that test...you may have a hardware related issue...

Good luck!

I have a 6400 @ 3.2 , and Orthos fails at 4 hours.. It failed in 4 hours at 2.8 also..

Otherwise, I'm 24 x7 stable with all the stuff I do .. Mostly Distributed Net's RC5-72 project and video work .. I haven't rebooted in 4days ..

 

[jhh979s]

I have a P5W DH, I know its different but I had a few issues when OCing my e6400. I read a few forums and found that setting the DRAM timings by SPD to "enabled" solved my problems. Its worth a shot.

Ugh....THis is killing me....Again, This is the best set up I have had so far. I have tried all the suggestions, but no luck. To be honest, all the different settings are starting to blend together. I am just wondering what I really need to concentrate on? FSB? Memeory Voltage? V core???? ect. I installed the latest bios(706) and ran the blended test (default setting) and I t ran for about 5 hours (I shut her down).

RUn SmallFFT for 12hours and if it doesn't crash you know your CPU is good. Then run memtest to check memory.
