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:rolleyes:

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.
 
Make sure the ram is set to 2 in the bios options.

You will need to press Ctrl+F1 at the main bios screen to see more options.
 
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

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.

Really? That's handy to know, as i have the F7 BIOS (came with the board) and am having no end of trouble getting my overclock stable.

It will be stable through 6-7 hours of orthos but locks up the screen after 10mins of UT3.

May have to look at the F11 BIOS then. Sorry for the hijack.
 
I am running F12a bios because the system-2 fan would not go to full speed
as this is were i plug in the fan that keeps my 8800GTS cool.

I am runing a Duo2 6300 @2.4 at 1.06V, ram at 668 rock steady now for months.
temps @ 21c. No reason to overclock it more as i cant find any program
that needs it.

Also if you have a HD on the Intel sata2 port one can you look in device
manager and see if the DMA mode is set to 5 or six please.
As i cant make my HD go to DMA mode 6 when it should.

Have you got a spare power suply to see if its that.
 
I wouldn't worry about upping the MCH or FSB voltage on the P35 chipset board. I went up to 512 FSB before mine needed upping using a lower cpu multiplier.

In bios disable anything not use >>>> floppy drive/Firerwire/IDE/ print/com port etc
Disable C1E
Disable EIST

Both I found made system unstable between 1.46 and 1.51 CPU volts.

In overclocking page

Disable Graphics booster
Disable C.I.A.2
DLL setting on option 1

If you are setting RAM timings manually only manually set:-

CAS
RAS to CAS
RAS precharge
TRAS
Me for example 5,5,5,15 but that is in excess of 1000mhz with PC6400. Also upped the DDR overvolt to +0.2.

All other to auto except ACT DELAY which can cause BIG instability issues as it doesn't seem to auto set. Set that to 42 to be on the safe side. It has a tiny impact on performance but but can destroy an overclock.

The sudden restarts after applying settings is normal on this board and if the settings are not holding its a sign something has been set very wrong.

Apart from the motherboard what kit are you using, CPU/RAM?

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
 
I had the overclock not sticking problem on a p35 ds3 after i updated to the latest bios ...turns out clearing the cmos sorted it.

Our systems are almost exactly the same.:p

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?

It is 10 hours stable at 3.8 so far at 1.55 bios volts but I've gone back to 3.6 again until I get a better CPU block. Hits 63C at times with a Themrochill PA 2.120 and a 240 blackice gts so I wouldn't try going that far with out a similar amount of cooling.

F11 got me a better overclock than F8 and has sorted out memory error issues in between the two bios's. It has loadline calibration, which I think sorts out droop issues. Has more CPU support.

Photos of bios settings to get me 3.6. I could go down on the CPU volts a step or two just over do it a bit to make sure its stable.
CLICK IT

from my experience, the F4 BIOS was the best. Any bios up to the F11 were completely unstable, and the F11 BIOS can't support as high a memory clock but it stable at 1:1 instead of 4:5

Still happening to me now from cold boot with my p35cds3r ..thought it was sorted.
 
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.

I found that too but even working at lower frequency it still benched a faster score.

My P35C-DS3 board wouldn't hold its overclock yesterday - the BIOS wouldn't save right... well, just what the original poster said. I did have a USB drive plugged in at the time. Will fiddle around tonight and see if I can fix it. I need the USB mouse and keyboard for OSx86 though.
