P35C DS3R Reboot Cycle

[Dominik]

Greetings,
yesterday i assembled my new System with those Specs:

Mainboard:
Gigabyte GA-P35C-DS3R P35
CPU:
Intel Pentium E5200 2x2.5GHz
RAM:
2x2048MB Mushkin SP3-10666 CL9 KIT
GPU:
ATI X1900XT
PSU:
Hyper 700W

After i assembled it i tried to run some Tests, and the System shows the "Constant Reboot Cycle" behaviour described by many Users in the Forum.
I read through all the Threads but have not yet found a Thread containing a Solution to my Problem.
Strangely the System works after 3-10 Reboots and runs rock solid ( i ran a 12 Hour Burn in Ram/Cpu Test), but seems to reset to some default Bios Settings.
What is even stranger is the Fact that this Problem only seems to occur in Dual Channel Mode with 2 Ramsticks inserted, i tried it with only one Stick inserted, and i had no Problems anymore.
I updated to Bios Rev F12e, tried the most relaxed Memory Timings (i maxed every Latency), tried to run the 1066 Memory on a much lower Frequency, but nothing seems to help.


Now i am a little dissappointed because most of the Mainboards i used before had been Gigabyte Mainboards, all were rock stable, very reliable and well designed (i never had Problems of any Mainboard-related sort)

I would be very happy if anyone knows a Solution or if i would hear any official Statement regarding this Matter.

Is my English really so bad that noone understands my Problem? :-D

Re: P35C DS3R Reboot Cycle

In the MIT section of the bios alter:-

1) Performance Enhance = Standard

And if that is Mushkin DDR3 (i'm guessing it may be)

2) tRFC = 70 - 80 (Refresh To Act Delay)
3) DDR3 voltage = 1.6 - 1.7volts ***

*** What is the Max warrantied Voltage rating of your memory as stated by Mushkin. This can usually be found on a sticker attached to the module.


What frequency are you running your Ram at?

Re: P35C DS3R Reboot Cycle

Thank you VorLonUK! , i will try that.
Yes it is DDR3 and the Bios says it runs with "800" (Mhz), but i also tried some of the lower Preferences.

Re: P35C DS3R Reboot Cycle

This is 1333Mhz ram, not 1066Mhz, just so you know for sure.

Can you please post the model # of your ram for us, it is on the sticker on the ram

And then please fill this in with what settings you are trying to save and use that fail to boot, so we can see what you are trying, and we can advise you of what you need to change.

This is Just a template I use to ask people their settings, pay no attention to the numbers in it, replace with yours
