I have a perplexing problem and have worked on it for a couple weeks now and need assistance.
I had been running on a E6600 at 410x8 for the longest time (months). Did a normal reboot one day and the system did the double start (as if something were wrong) and reset the overclock. No biggie I thought, just go into the Bios and load back up my overclock profile. No dice. No matter what setting/voltage I have tried since then it won't get past the memory test before it does the double boot and resets the settings.
I have even tried just to manually enter in the stock speeds instead of choosing auto to see if that worked (like it would before) and nothing. The only thing that will completely boot is if the FSB is set to the default settings.
I even tried another CPU (e6550) to see if I cooked something in the processor....no dice either (meaning no overclock in the bios). The weird thing is that I can use Easytune (last resort) to overclock and it works fine, however the settings will not survive a reboot. But it does overclock fine.
I need to retain what hair I have left, so help me
EDIT: I even tried different ram....same result (ram test fine at all speeds I have tried with memtest)
I did some initial o/c last night and the best 'stable' I could do was 3Ghz 9 * 334 , I've tried ( 9 * 356) but I was rebooting while stressing the system, no matter how much voltage I'v e applied up to 1.45V....LOL My memory was running in 4-5-4-11 @ 2.10V, I've tried 5-5-5-15 @ 2.10 without luck...
I'll try 8 * 400 tonight.... How should I setup my memory (timings/voltage) for it?
Any other sugestions?
TIA

I have had my e6400 OC'd to 2.8ghz for awhile now. Setup in mobo was:
FSB: 400
Ram: 2 (1:1)
Multiplier: 7
Voltage: 1.325
Now, I just got my 120 extreme, which means my temperatures are a lot lower so I decided to push this chip more. So my initial thought was to just increase the multiplier to 8. No luck. I then pushed the voltage up to 1.4 and still no luck. What is up with that? 1.4v should be able to make it run at 3.2GHZ no?. Any thoughts?

I'm new to OC but wanted to give it a shot based on the hardware I have purchased over the last 6 months. I thought I could get a little extra horsepower out of my chip - no gaming, just office type applications. Eventually, I might even get a game or two
My setup is:
Vista Ultimate 32 bit
965P-DS3 Rev 1.3 with F11 bios
E6600
XFX Geforce 7600 GS with latest drivers (169.25)
Corsair xms2 (2 x 1GB)
Zalman 9500 cooling
I started by stepping though the tutorial to get my baseline, however when I do this, the system seems to run very slow. It is slow to load at startup, slow to load programs, and seems to be chugging along (at a slow pace). Prior to this, I would startup and the welcome screen would pop up within seconds, now it takes about 45 seconds. When opening CPU-z, Coretemp, or any program, it takes about 5 seconds for the UAC to popup asking if it is okay to run this program.
Also, I get "Display driver nvlddmkm has stopped responding and has been recovered." I'm thinking that this could be the root of the problem, but I'm not sure.
When I load the fail safe values in the bios, everything runs quickly again, although the processor is underclocked at 1.6. This thing should be very fast and I can't seem to get even the baseline to work. Any ideas on where to start troubleshooting? Could it be something with the video drivers? Why does the fail safe run so fast compared to the optomized defaults?
Thanks in advance for any suggestions,
John
I'm interested in what you find about this, rbreding. I have similar issues with my P35-DS3L board. Although in my case I only had the board for a week (stable OC and all) before the first "double boot" occured and now it's very flaky. It seems almost ok if I leave the system voltages etc on auto. But any time I try and adjust settings manually to reduce heat, bigtime problems occur. Even doing nothing but enabling FSB freq control but leaving it on the default for my processor can make it reset!I have a perplexing problem and have worked on it for a couple weeks now and need assistance.
OCZ 4GB DDR2-800 (5-4-4-15 2.1V),
This is only a guess, but I would immedately set your memory volate to 2.1V if you have not already done so. Set the MCH voltage to +.2 to help drive that 4GB of memory.
The second thing to try is to remove ram and just run 2 GB.
I will need detailed information on exactly what all the MIT menu items are set at to really make a good guess at what is going on.
I will fix the orthos link. Thanks.
I also have an e6400(DS3 P965 r3.3) and I got it to 3Ghz and don't use a NB fan but my CPU heatsink/fan has fins that deflect air to blow on it. The thermal paste used on the NB isn't always applied evenly and that could be part of your problem too. If you have some good thermal paste you might want to reapply some on the NB. Also what board do you have?
So does anyone have any ideas about my problem? Is it my northbridge overheating?
The long and the short of it is, put the fan on the NB, $5 and couple of dabs of RTV silicone adhesive and you do not have to worry about it. There is no way to determine exactly what your issue may be as there is insufficient information. What memory do you use and what is the manuf suggested voltage ? What were the FSB and multiplier setting etc. etc. It seems the cpu Heatsink/fan is working fine so that is probally not the issue.

Ok, I just finished reading pretty much the entire thread. Great work Bill!
You do not provide sufficient details. Is the drive always plugged in ? Is it seen in the bios but not the OS ? Not ever seen ? etc. etc. This thread has some good ideas. http://episteme.arstechnica.com/eve/forums/a/tpc/f/24609792/m/644008649831 and in the thread it indicates the fault might be with Intel's Storage manager software. The OS should have been installed with AHCI drivers either with the floppy method for XP or using Vista built in. Set the bios to AHCI and raid even if you dont use that functions so the AHCI drivers that use "Hot Swap" are available to the system. Set the MB bios like you were using raid but just leave the drives as "standalone drive" in the raid setup.I've got a Gigabyte GA-P35-DS3L that's giving me double boots (cold boot problem?) and loses OC all the time. I'm also having a problem running my external HD which is running on eSATA (doesn't work in USB mode either).
First question, do you have any suggestions about how to get my external drive working?
A Dell.Second question, what do you recommend I buy after I sell this piece of sh*t MB?
You do not provide sufficient details.
I am suddenly having issues with this board and rebooting. It appears to be shutting down but then the monitor goes black and the system lights stay on. I then turn off the power supply switch and when I turn it back on, the computer doesn't turn on when I hit the power switch. If I walk away from it for 10-15 minutes, I will find it turned on already.
Here are my specs:
Vista Home Premium 32-bit
E6420
DS3 rev 3.3 Bios F12
XFX Geforce 8800GTS 320MB
Patriot Extreme 800 1GBx2
I had the system overclocked at 8x400 for awhile, but then when I had issues I removed the overclock and still get the same problem.
I read about warm boot issues and tried my PCI-e at 101 and 105 Mhz, added +.1 volts to everything for stability, but still have the issue.
I also recently switched the HDD from the purple port to the yellow and disabled the AHCI options in the BIOS. Could this have something to do with it?
I tried disabling legacy USB devices and my machine booted with the external drive this morning. I'll try it again tonight to see if it was a fluke.
I tried enabling AHCI but Vista just crashed. I'm guessing I have to enable the Vista drivers in the registry before enabling it. I'll try that tonight too.
Agree 100%What a superbly detailed question!
They are exactly the same in function and you can use whichever one want as far as I know. You WIN ! You made me look at the manual
What the deal seems to be is one is labeled PWR LED and one is labeled MSG LED and if the manual can be believed they both operate the same way.
S0 On
S1 Blinking
S3/S4/S5 Off
The difference is one is 3 pin and the other is 2 pin. If you have a case with a 3 pin connector for the power/sleep led you use the three pin separate header. I have never used one but I believe some cases have a combination green/yellow led and the three pin connection will cause the LED to be green when the computer is in the ON state and then the same LED will be blinking yellow when in sleep. If your power LED has only 2 pins use the one with the other front panel connections. And if you case has 2 LEDs do what you think best cause I don't know, and would just try and see. Many times I have had to modify the LED connection/connector by moving a pin/wire over in the casing.
Dear Motherboard Manufacturers.
Next big trade show please get all together, get drunk or whatever, hire some boobs if you have too, and sit down and decide on a standardized Front Panel connector layout and remember to include a couple of extra pins. ITs ONLY BEEN 20+ FRAKING YEARS . And after you sober up, tell the case manuf about it too. Thanks, appreciate that. Oh and it would be cool to have extra pins for a drive activity LED for each SATA drive so you might need to invite Intel too. One connector to rule the Front Panel...
Bill.
PS Dont be worried about giving the CPU a little extra voltage as your testing continues, you might be amazed at what 1.375V would do.
