The Unofficial Gigabyte GA-P35C-DS3R P35 Board Thread

[mrfatboy]

It's time to replace it.

ANOTHER UPDATE: You will be amazed!!!!!!!!!!!

I had tested the memory (read earlier posts) and 1 stick failed the other passed in Prime. The voltage was set to +0.3 (the memory is rated for 2.1V (1.8+0.3))

I dropped the voltage to +0.0 in the bios and the memory that was crashing passed Prime for 3 hours. I then decided to up the timings to 3 3 3 12 and it worked again for 9 hours last night. Bear in mind this is the memory that was crashing within 1 minute.

I have heard that this board may overvolt memory (absolutely crazy!!!!!) - so maybe one of the memory sticks dont like this higher memory voltage (especially if it the motherboard is overvolting it).

Also thinking back I had the memory voltage on AUTO when doing the first tests so maybe the errors occured before as the motherboard was AUTO putting it on a higher volt? I know im clutching at straws here.........

Hi there

I jus bought this motherboard and connected everything up but the CPU fan doesnt work im running a Intel Duo core E6750 2.66ghz 1333 FSB

Does the board have some sorta BIOS setup where the CPU fan will come only come on when the chip gets warm enough?

 

[spluff]

the fan doesnt start straight away on mine takes around 3 seconds....... hope that helps ( i changed nothing in bios)

Use this chart to adjust your memory voltages. I think you should be using +.2v to get a 2.1v (2.13v acutal). Then try to isolate the problem from there.

Delta---------Actual voltage
+.0v----------2.00v
+.1v----------2.00v
+.2v----------2.13v
+.3v----------2.24v
+.4v----------2.37v

thanks mate - CRAZY though isnt it............ that all these problems have occured because Gigabyte cant even get the voltages correct!!!!!!!!!

I am still a bit lost why 1 stick of memory would fail +0.3 and the other was fine, but the memory was fine at +0.0.

I would have thought it was the other way around.........

The only explanation is that the +0.3 as we all seem to understand is overvolting and this voltage is causing the memory to error.......

WEIRD!!!!!!!!

Thing is now I have received my memory so I dont know which to send back........ what would you do?

I would first set my memory to spec. I assume your memory is 2.1v @4-4-4-12. So set accoordingly with +.2v on the mem voltage. Then run your tests. They should be no errors. What ever fails send back. Good luck.

there is an option in the bios to disable this behavior and run the CPU fan full blast at all times. It is in the PC health menu called smart fan control method, disable this and your fan will run at all times even when the chip is cool.

Yes, to get best GPU and "System" temps, put a 120mm at bottom of your case, blowing both at gpu and SB heatsink/ICH9R. My 8800GTS ambient temp and system temp now both show the same, 37-38C.

Be VERY careful moving all SATA cords away from the fan: idle system temp rose to 51C when they blocked airflow ! Gaming system temp was 55C...with cords away; <40C gaming !

Hey All,

Stumbled across this excellent thread after I had purchased a new GA-P35C-DS3R board at the weekend and was having some problems with it. I have read through bits of it (Yes its massive) but I have a qu regarding the northbridge chip

I upgraded the bios when I got it and it is giving a temperature reading in the PC health section now.... G(MCH) I believe it is (computer is at uni house so I can't check at the min) Anyway after playing C&C3 for around an hour I checked the temperatures and the temp for G(MCH) was sitting at 70oC! Surely there is something wrong here? Is this not way to high?

The G(MCH) refers to the Northbridge (P35 CHip) right??.....When I got the board it had the problem sometimes seem whereby the heatsink was not connected right to the P35 chip....was basically see-sawing on it and I had to remove it and apply new thermal paste!! However this was my first time doing this and I am now afraid I didn't do the paste correctly hence the high temperature...

so basically is the temp reading too high? What is the max. temp allowed? Will the system auto shut down if it exceeds the recommended temp? And what can I do to fix it!!?!

Thanks for your help!!

 

[mrfatboy]

starfoxy, welcome to the forum!


1st, please put your rig in your sig so we all know what we are dealing with.

2nd, We need to know your ambient temp (room).

3rd, Are your overclocking now? what are you settings?

Just has a reference my Northbridge is 47C stressed. So yes, you are definately higher than me There is a link around here that talks about the northbridge temp. Just search for it. But generally, I think you are still in the safe zone.

Also, check out this thread. Tons of info.


6750 - p35c OC thread

 

[starfoxy]

Added Rig into my sig..... Sorry I forgot to say I haven't tried overclocking yet, I only finished the build at the weekend.

Room Temperature I would have to check when I get back up to the house today but it is usually around 25/30oC!

Thanks will give that thread a read to and see what I can find


EDIT: When I turned on my computer today it was sitting at 66oC!!!! And it hadn't been switched on in days....how can that be?!

5t3vo, do you want to take this one? :laugh: hmmmm! what could it be?

 

[shimurlz]

I finally set up my new pc based on this mobo but i'm having some problems with it. The first and most annoying problem is with the onboard LAN. I don't know why when i boot the system the onboard lan doesn't start itself until winxp pass the load screen. This represents no problem when using win xp because after it loads the onboard lan starts and operates normally. But when using linux (ubuntu), after the linux loads, the onboard lan does not start itself like it happens with win xp and i end up without lan functionallity. What could i do to solve this problem ? What i found to help is enter the bios before load ubuntu and start the smart lan, when i do this the onboard lan works in ubuntu.

The other annoying problem is when i enable in bios the option CPU FAN Fail Warning, when enabled i always got an odd bios beep sound (much longer and louder than normal) but the system starts normally after it.

i'm using the F4 BIOS, but this problems also happens with other bios versions (F2 and F3).

Hi, i'm having a problem with this board and was wondering if any of you can help.

I've been trying to use my old optical DVD drives and HDD through the IDE port on the motherboard so I can install windows and then transfer over all my old documents etc from the old HDD.

However the motherboard fails to reconise all of them (however, it did see one of the hard drives once, but then I tried a different cable and it didnt work, then tried the original cable that I just used and then that wouldn't work.)

I've tried resetting the BIOS, using different jumpers on the drives (fairly sure i dont need them if im only connecting one at a time though.), different IDE and power cables from the PSU and nothing seems to work.

Any suggestions?

My Specs are;
2GB (2x1GB) CorsairTwinX XMS2, DDR2
1 x EVGA 8800GTS SuperClocked 320MB DDR3 DVI PCI-E Graphics Card
1 x Corsair VX450WUK 450W PSU
400 Gb Western Digital WD4000AAKS Caviar SE16, SATA300, 7200 rpm, 16MB Cache, 9 ms

Been away for a while guys, but haven't missed much by looks of it. I replied to starfoxy's PM with details on my NB fan setup.

starfoxy, where are you getting this reading of 70C from? If its the system temp in speedfan or something then this isnt the mch temp. The sensor is on the mobo, allegedly near to the ich9r chip. What's your case ventilation like?

 

[mrfatboy]

Welcome back, 5t3vo

I read a post a couple of weeks back about NB temp reading. Supposedly there is a NB temp reading in the BIOS in the PC health section. But only when you are not overclocking! I think there was something else you had to have to set to have this reading show up.

Search for "NB or Northbridge temp" for exact directions. I just ended up putting a digital thermometer on my NB to get the temp. I wanted the OC temp anyway.

 

[starfoxy]

Yea mrfatboy that is where I got the temperature from....if you have the bios set up so that Intel's QST controls the cooling AND no OC'in then a temp for G(MCH) is shown. However I changed the cooling method and since then when I changed it back to what I thought displayed this temperature it didn't so I have been unable to monitor it for a few days now

I am using a P182 Case.....pretty good vent I think!....Have used the computer all week for some pretty intense gaming and haven't had any problems yet (Fingers Crossed!) 40mm fan ordered, will fit according to your PM Stevo, thanks for your help guys

 

[sgrinavi]

With regards to the system in my sig (GA-P35C-DS3R)...

Does this sound like an MB issue?

A few weeks ago I had an issue with my video; there was not any. I tried everything and nothing helped. I was getting ready to RMA the board and removed it. I had the whole thing apart and then figured I would test it with the board out of the system. It worked. SO.. I put it back in the case and it still worked.

Over the next few days later I upgraded 2 sticks of RAM to match my Mushkins, replaced a hard drive, installed FEAR and a few other bits of software. One day I start getting BSODs, I can not pinpoint exactly when, I set the BIOS back to stock speeds (without any help) then the video started cutting out again, reinstalled drivers, removed programs, removed ram, etc, etc, etc.. The video output randomly returned, I switched out video cards & memory - without any change.....

The BSOD dumps do not yeild consistant results; it appears to be an IRQ conflict, but nothing shows up in device manager.

I removed the RAID and, on a new hard drive, reinstalled the OS (xp x64).

1. Installed windows

2. Added net card drivers

3. Added wireless drivers

4. Added chipset drivers -- which worked at first, showed as USB 2.0, but after a re-boot the SB ports came up with a yellow flag in the device manager and did not work. Once I rolled each USB device driver back they returned, but as 1.1 ports... uggggggggggg

5. Tried to install on board sound drivers, failed looking for updated HD drivers

6. Tried to install SP2, BSOD started AGAIN!

7. Rolled back system to step 2.

8. Tried to install SP2, BSODs almost instantly.



Any Ideas??

I'm having trouble clocking the FSB any higher than 389 MHz on a GA-P35-DS3R. I've tried increasing the FSB and MCH voltage, but to no avail. Anyone have tips for overclocking the FSB on this board?

I have had mine up to 440 at a 7x cpu multi but did not see any point in stressing the system that much....

What processor & ram are you running? whats the cpu multi? did you lower the ram multi down to 2?

 

[4836348435]

I have a G0 Q6600 and Crucial PC2-8500. I've tried CPU multipliers between 6-9 while leaving the RAM multiplier at 2. This works as long as the FSB is 389 MHz or lower. As soon as I set it to 390 MHz or higher the system becomes unstable--even if the multiplier is 6. This is preventing me from overclocking any higher than 3.5 GHz (9x 389 MHz).

 

[sgrinavi]

Have you tried with loose RAM timings?

 

[4836348435]

Yes, I've tried with loose RAM timings. Still, I should't need to, right? With a multiplier of 2x and 389 MHz, the RAM is only running at 778 MHz.

 

[sgrinavi]

I was stuck at 3.4 until I jacked the voltage up to read 1.41 in cpu-z.. I think it was about 1.48 on the MB, but I don't recall.

389x9 is about average under air for g0 OC's...

Do you need to leave your RAM loose? I dunno, it can't hurt tho.
