Gigabyte GA-P35-DS4 fails to keep overclock, fails to boot from cold?

[Biomanic]

Hi guys, im new here.

I have this problem and I hope somone can help me with. I just changed my motherboard from a 680i based chipset to a P35. This board fails to keep any overclock what so ever and what I found it to be is for some reason during the saving process it shuts down the power and back on way to fast. This causes some problem with the bios and fails to post, thus rests my clock to default.

I had got it to post a few times and all my stability test shows my overclock is fine. I thought I was sorted when I then shut down my pc and booted from cold. I found out that my USB drive was stoping the post boot, it will always reset my bios to default

So we have two issues here.

1) Fails to post during the save of a overclock.
2) Fails to cold boot when a external drive is pluged in, not till it resets the bios defaults.

Does anyone have these problems and if so have you sorted them out?

Thanks.

Yes I have both USB mouse and keyboard off in bios. I have F8 bios.

deuse, when yu say ram at 2 what do you mean, the devider? I have my devider to match the rams stock frequency 800mhz, I think its 2.4.

Thanks.

I had the same problem with my 965 DS3, you need to up the MCH voltage to +0.1 for the overclock to stick

Naud

Iv just tryed to jump the voltage to 0.100v and it makes no difference. Even If I overclock to 1mhz above stock it will not retain the overclock. I prety sure its because the way it shuts down and back on so fast. If I twitch my PSU off when bios turns the pc off, then I choose when to boot back up, the overclock stays.

Thanks for the info, il check later on today and see if iv missed anything.

My pc spec is as follows..

ThermalTake Monzart TX, Enermax 720w, GB P35-DS4, Intel e6600 @ 3ghz(Water cooled),Ocz Reaper PC 640 2Gb ,8800gt oc on water, Audigy Platnum. Pioneer 109 DVDRW. WD 250gb Sata II, Seagate, 120gb Sata.Silverprop Cyclone EV block, XSPC Radiator,D5 pump

Our systems are almost exactly the same.

How on earth did you mannage to get 3.6ghz out of your e6600? You know what, I cant even get 3.1ghz, what settings you using?

khemist, was your problem only happining when the pc had to shut down to set the overclock? Any seting I make that dont require the complete shut down always stayed.

What does bios F11 have over F8?

I sorted my cold boot out. For me it was legasy USB sotrage detect fuction on that gave me the cold boot.

YZFAndy, I see you have all the items enabled in bios that iv been told to disable.

Iv been at this for a week now, and when I say a week its been full on.

The cold boot issue was for sure having USB legacy detect turn on in bios. Either way usb legacy detect didnt work and would force the power to shut down and reset bios.

The problem regarding keeping clock settings is very hit and miss and somtimes it would hold while other not. For a test I overclocked by only 30mhz, first boot kept it, second reset the bios. I then loaded my stable 3.06ghz profile and it loaded? I then went back to a stock clock then back to the 3.06ghz and it failed. When I got the 3.06ghz to stick, I went into windows and did 3 hours of TAT tests, it was fine. I then went into my other windows but found that the mouse wasnt working so I hit the reset button, this reset but then shut down the pc power and guess what, it reset to stock.

Iv changed the Gfx card, Moved the memory in different slots, changed the PSU, under clocked the memory and timings. flashed bios to F8 and F11 and cleared CMOS. The only thing I havent tryed is different memory. Then later on today I found a review on my very memory, the Ocz Reaper pc640 which was tested on this very board, the system clocked no problem and in fact this memory went to 1000mhz.

Anyone solve this as its still with me and cant put up with it no longer. If I even pull the power pllug when the pc is off, next time I power the pc Up all my settings are gone after 3 recycle post attempts.
