Gigabyte GA-P35-DS3L Thread

Awesome. Looking good. I'm trying for 3.6 GHz and am at 3.48 right now. Going to go for the next step right now.

Having a bit of a problem. Once my computer has been running for some time, all procceses go to core0 and only core0. On a fresh boot of the system, when I run Prime95, all 4 cores are stressed. But when this problem occurs and I run Prime95 it only stresses core0. I do not have a way to reliably replicate it, other than just using my system as normal until it occurs.
This happens on essentially stock settings. I have only disabled the following:

No-Execute Memory Protect
CPU Enhanced Halt
CPU Thermal Monitor
CPU EIST Function.

The only other thing I changed was the memory voltage to match what my memory was rated for. The problem occurred at both the to 1.8V and the 2.2V the memory is rated at.

System Specs:
Q6600 Stepping B, Revision G0
Gigabyte GA-P35-DS3L, Rev. A2, Bios F5
Crucial Ballistix 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)
BFG 8800GT OC 512MB
COOLER MASTER Real Power Pro 650W PSU
Zalman 9500A
Not sure where to start to even track down this problem. Any help would be much appreciated.

Hi guys, im running at 2.4GHz now (from 2.2) but just wondering if any settings will lower my temps (even just a little...) because its running at about 28C idle but when i stress it with Orthos it goes up to 59-60C... thats a whole 32C jump..so is there any way to lower it slightly until i can get a new HSF?

There's not much you can do other than stepping down your core voltage (which will affect your stability) or reducing your OC. Core voltage is the single biggest factor in heat production though.

A couple things you could try:

- Make sure your cabling isn't impeding your airflow in your case.
- If you have room for another fan, perhaps add one more fan to your case.

That load temp isn't too bad, even though it's a large jump. Most of the advice I've read from experienced OCers have indicated that as long as your load temps stay at around 60C you're fine (and many of them are happy as long as it's below 70C). Your chip's thermal specification is 73C, so a load temp of 59 to 60 shouldn't be something to worry about.

Once you get an aftermarket HSF on there you should notice a big difference. Be sure to use a good quality thermal paste as well - and make sure it's applied properly. Cheers.

I just got this motherboard to overclock my E4300. I successfully overclocked the CPU to 2997 Mhz Using 333 FSB and OCZ DDR 667 Gold series. The core voltage is set at auto and it does get hotter than stock speed (58 orthos stock - 71 orthos OC) but it doesn't get any errors after 8 hrs running. It runs very smooth especially in games. Now the problem is that just last night I noticed that if I shutdown the PC (first time since I've got the motherboard) the BIOS will reset the CPU to default settings when I power back up. Resetting and keeping it on it will run 24/7 at OC settings but if powered down and back up it will reset to default. Anyone have any ideas what is causing this, is it heat related? BTW I have the latest BIOS F7.

Any help greatly appreciated. THX

Do you have an external HDD connected (USB)? I read about a guy having this same problem with his board and it turned out it was because he had a USB external hard drive connected and the board was trying to boot from the external drive. Once he disconnected the drive before booting, it would keep his settings.

Failing that, check your CLR_CMOS pins to make sure the jumper hasn't been left on it in error, and maybe check your battery isn't dead.

No, I don't have an external hard-drive connected, but everything else I have connected is through the USB, printer, mouse, keyboard, webcam. Also, I do believe that the battery is OK because it still holds all my setings including the saved CMOS profiles I have saved. I have started experimenting with some BIOS settings, first I disabled the C1E, EIST, and Auto voltage settings. My theory is that perhaps the BIOS doesn't react fast enough to adjust the voltage at start once the CPU fluctuates in speed with the EIST and therfore believes that the V setting is not enough for the OC. So I'm trying to find the min stable V for the OC with no throttling. enabled. Let you guys know my results. Also any further suggestions would be helpful.

BTW, When I set a specific V in Bios and I go to windows CPU-Z has a different number! For example, I have 1.35 set in Bios right now and in CPU-Z it says 1.28-1.296 fluctuating, Which is correct/more accurate?

I was concerned about this as well and everything I've read has indicated that CPU-z is more accurate. So I'm going by that. I have my BIOS core voltage set to 1.4 something (can't remember the exact value off the top of my head), but CPU-z is showing 1.392 volts). I believe CPU-z is correct.

The fluctuation is due to a phenomenon known as vdroop. Mine drops by .016 volts under load. Sometimes the drop is a further .016 volts and it will fluctuate between the two voltage droops. I have a theory about that though, as it seems the second droop only occurs when my OC isn't stable.

Anyway, as far as your BIOS resetting goes, I don't have any other ideas other than make sure EIST is off. I've read a number of threads on various boards that mention this happening, but it doesn't seem to be happening to everyone. I've got my chip OCed to 3.52 GHz now with a vcore of (according to CPU-z 1.392 volts). I shut it off every night before I go to bed and fire it up again in the morning and so far the BIOS has never reset on me.

My board's the revision 2.0 and the BIOS is F5 though.

*edit* Oh, my keyboard and mouse are both USB (I'm using the Logitech G11 keyboard and have my mouse plugged into one of the keyboard USB ports). My printer is from the Stone Age, so it's connected via parallel port. I don't have anything else connected as yet.

Thanks for the info. I've disabled EIST and C1E and am currently working my way up on the voltage settings. I just turned off the coputer for a few minutes and powered it back up and the settings did not reset! Don't know which of the actions I took fixed the problem but I need further testing to be sure that it is really fixed and won't happen again. I also have the rev 2 board but the latest bios.

BTW does anyone else have an E4300 rev L2 stepping 2 CPU with a Tj max of 100??? Just wondering what temps evryone else is getting. To me they seem high compared to other core 2 duo chips. Also since it is a 100 Tj max does that mean that I am safe @ 71 C orthos? If I set the auto fan speed setting in Bios the fan runs at a low speed and goes a little higher but not full speed at full load, so I'm assuming that the temps are fine otherwise the cpu would crank the fan full speed. Anyone know?
