The Unofficial Gigabyte GA-P35C-DS3R P35 Board Thread

[mrfatboy]

There is a new beta bios (F4i). The "changes" say exactly the same thing as the F4g version. Does anybody know anymore about the new bios?

here is the link

BIOS F4i

 

[SniperDaws]

Im using that bios now, the only thing i can see thats diffrent is the fan speed control is missing the intel option.

Wow those tuniqs truly are massive!

Nice

Forget auto overclocking, follow one of the overclocking quides & do it manually. You'll get far better results & stability. Here's the settings I use:

Advanced BIOS Features
-----------------------------
Limit CPUID Max to 3 = Disabled
No Execute Memory Protect = Disabled
CIE = Disabled
TM2 = Disabled
CPU EIST = Disabled
Virtualization = Disabled

MB Intelligent Tweaker - press CTRL-F1 before going into this screen to bring up extra options
--------------------------
Robust Graphics Booster = Disabled
CPU Host Clock Control = Enabled
PCI Express Frequency = 100
C.I.A.2 = Disabled
Performance Enhance = Standard
System Memory Multplier = 2.00
High Speed RAM DLL Settings = Option 1 (dont think this does anything when manual timings are set)
DRAM Timing Selectable = Manual
System Voltage Control = Manual

Then its just a case of playing with the CPU Host Frequency & voltages (while monitoring temps of course).

Remember this board defaults DDR voltage to 1.8v. The XMS is rated at 1.9-2.2v so your instability could be a result of that. Up it a notch or two. I have mine set at +0.4v (2.2v) for running at 450MHz CL4.

Also you might find the RAM timings are defaulted to a safe setting of 5-5-5-18 (mine were) so you'll need to adjust these manually to 4-4-4-12.

Hi @ll, Dear Users of the P35C-DS3R,

I would recommend not to play to much with those beta bioses. It seems that the F4G could kill your MB. I killed mine with the F2. There seems to be a problem with some boards and especially after the F4G upgrade.
I assure you it's no fun, mine was dead after 2 days.

But see for yourself : http://forums.tweaktown.com/showthread.php?t=25051

I have now the second one for a day, lets see what future brings.
Greetings

I've been running the f4g bios since I built this system. It's been about 4 weeks now. So far so good. Knock on wood

 

[MRGOOCH]

There is a new Bios rev. F6a beta. One of the things it corrects is a keyboard issue. Anyone know what that was?

 

[5t3v0]

Where's that available? Version F4i is the highest on the Gigabyte UK site. This too claims to "Enhance PS2 keyboard function" in the description. Perhaps its to fix the fact that it wont restart from the keyboard after going into hibernation. Has anyone had any luck with this? I have to press the power button with the F2 BIOS. I've not had the balls to try a beta BIOS.

 

[SniperDaws]

Thanks mate, ill give it a go.

so my ram needs to be set at +1 to make it 1.9v ?


im going to mess around with it in the morning, im getting mixed results with temps though, is it safe to say that the bios temps on this board are accurate?

YES and YES. The core temps are not accurate though with speedfan, et al. You need to add 15C to core temps.

I would go even higher. According to Corsair specs our RAMs need 2.1v to run at 4-4-4-12 at 800MHz, i.e. +0.3v on this board. If OCing over 400MHz cpu freq, then you'll probably need to add more as I did.

BIOS temp is most accurate but you wont be able to watch it while testing. Most core temps are dubious so just watch the CPU temp in whatever app you're using.

That cant be right cos ive had mine running at 80c if thats the case.

 

[5t3v0]

Are you saying you're hitting 65C already? I thought you were still on stock.

It's definately right for the 6750 chips. I thought it applied to all G0 steppings. I could be wrong but you definately better figure it out quick if I'm right.

This is stock running idle with a Vcore of 1.1, if i set it default in the bios its 1.27 which seems a little high for a G0.

this is exactly the same setup under load.

This is how bad rumors start. My brain works faster then my typing hands

Ok, if i go off my temps in my bios and speedfan im a happy chappy and feel i have room to overclock and increase the vcore a bit, if i go off the temps using Core Temp then im ready to take off this heatsink and throw it in my back yard for the dog to play with.

Heres a thing though while running Prime95 there is no way that my cpu's could be at 70-80c cos in my case it nice and cool, my northbridge is nice and cool (8cm fan pointing at it) and my cpu heatsink is only warm to the touch, if that thing was anywhere near 80c id be burning my hand.

So im up in arms, ive considered that the heatsink isnt making contact with the cpu so that could be why the heatsink isnt red hot, but then the temps would rise instant from idle to load instead of creeping up so there is good contact between heatsink and cpu.

im starting to lose the plot now, ive been sat messing about nearly 24/7 since tuesday and im tired

 

[mrfatboy]

I must be really tired also. Maybe it's the heat today. Anyway what versions of the temp sensor programs are you using. I forgot coretemps new version fix the temp problem.

I'm using

Coretemp 0.95.4 - These temps are accurate!!!!!!
Speedfan 4.33 beta 18 - you need to add 15C to CORE temps
Intel TAT tool 2.05.2006.0427 - You need to add 15C to CORE temps

My 6750 temps are for comparison using speedfan (adding 15C to core temps.

Note: only 15C needs to be add to Core temps. Everything else is fine.

northbridge 44C
cpu 23C
HD 31C
Core 0 33C
Core 1 33C
GPU 56C

Sorry for the confusion. My bad

 

[SniperDaws]

Ok, look at this and check out the Vcore and temps, should i reseat my heatsink ?


http://s14.photobucket.com/alb...&current=Hightemps.jpg


im thinking Yes now, if i have it at default vcore for this board ( 1.3v in bios and 1.24 in CPU-Z) im in the 70's and 80's according to Core Temp 0.95.4.

 

[5t3v0]

I very much doubt that your heatsink is the problem. Why dont you install one of the Gigabyte apps from the mobo cd & compare. I personally dont trust any of these apps too much, especially cross-mobo 3rd party ones. However, I have found that speedfan cpu temp at idle is very close to the BIOS cpu temp so I tend to go with that. I have also set the CPU Warning Temperature in the BIOS PC Health Status to 60C & have never had an alarm yet. You'd also have an unstable system if it was too hot. Dont be a slave to those core temps

im nearly smiling here mate, i also have my bios set to go off at 60C and i ramped my Vcore up quite a bit to see if it would work and when speedfan hits 60C then my bios alarm goes off, im going to stick with my bios temps and speedfan and just forget about my temps cos im sick and tired of this like i said before if it was 70-80C my pc would be like and oven simple as that.

Cheers Stevo


EDIT: i turned on Auto fan in bios, my temps are that low my fan has stopped, when i fire up Prime95 it kicks in when the temp goes up, with the fan off its still cool round my cpu and my temps arent rising.

Those temps are high but probably normal for a stock cooler. You really shoud throw that thing away and get a Tuniq Tower for $45. It's well worth it for peace of mind and give some room to play for OC. I have been reading other threads for Q6600 temps and everybody that has a tuniq or better seems to be in the 35C range. Just $45 and be done with it. Make sure it fits in your case.

 

[5t3v0]

SniperDaws, I presume you've seen this article? While your temps are in the safe range just now, you dont have any headroom for raising the vcore. As MrFB says, you definitely should get a better cooler. Even a cheaper brand like the AC Freezer which I have is adequate if you dont want to spend Tuniq Tower sort of cash. What's your case ventilation like & is it hot where you live? I would probably stick with disabling the cpu fan control & running 100%. Its easy fore me to say dont worry about core temps when mine aren't an issue here in bonny baltic Scotland. Keep at it mate. I wouldn't want you to fry that nice chip of yours.

Edit: What thermal grease did you use - the pre-applied stuff on the heatsink? It might be worth reseating with some AS5. Can you get it out without taking out the mobo?

 

[SniperDaws]

im convinced that Coretemp is incorrect, my temps idle now With CoreTemp is 40-40-38-35
and 58-58-56-54 on full load with Prime at a Vcore of 1.056 and its prime stable, but im going to buy the Arctic Freezer on monday, as for Case setup, its a full sized case 2x80mm fans blowing in from bottom front and 1x92 blowing out from rear middle of case and 1x92mm blowing out at rear top of case, all cables tidy and neat, all dust was cleaned out prior to install.

The cpu compound was the stuff that came on the heatsink, ill be adding AS5 to my order and ive read about how to apply it correctly for quad cores, a thin line down the centre, and im living in Manchester mate just a little down from you old fruit and temp in my room is 20 degree's so quite cool. ill let you know how i get on when my cooler arrives.

Best of luck! BTW, nice new sig. Seen one like that somewhere before
