Gigabyte GA-P35-DS3L Thread - Page 392

post #3911 of 4644
Well.. after many trials for now i manage to become down to 1,53v in BIOS , reads 1,504 idle and 1.488 under load and i had to increase 0.2 the MCH. temps went up to 76ºC wich is not rather good i asume (max temp acording to intel is 73.3). Will try going down bit more.. but i had reboots in orthos in lower levels wich is what scares me most..

Hey, I have a quick question

I've read that on this board the default ddr2 voltage is 1.8v

But with it set on normal, I plug in some 2v ram and it automatically is using 1.95v or 1.97v

Is this normal or do i need to reset my BIOS?

I ask because I don't think the ram needs that much voltage

AFAIK if it's set to auto the voltage will be read of the mem, you will see alot of specs where a stick has multiple voltages depending on the rate it's set at. But you can always override it and set it to what you want.

I've read some peops say thier voltage changes on reboot but I've never seen that myself.

I'd recommend setting it to what the manufacturers specs are and then boost it when the oc pushes it to failing.

IIRC the range is like 1.75-2.3 or so. I'm sure someone will pop in and correct me but this should give you an idea.

It failed at 1.513V in BIOS with FSB at +0.3 and MHC +0.2 (left orthos when i went work.. now im at work 3h later, conected from work to home and see that the computer had rebooted.. ie: orthos fail)

C1E and speedstep both dissabled.. whats going on.. this CPU was stable before at 1.44V ..now its not at 1,47 .. and temps have raised about 5ºC .. as i said before in orthos at 1h it reaches peaks of 76ºC ..it shouldnt

its not set on auto though, its set on "normal" and it still sets it to 1.97

how do i get the "default 1.8v" everyone says the board has

Link your mem. and fill in your system specs.

Good questions. The reason is that your RAM's stock setting is for 2.0, The boards default is 1.8, unless you manualy set the RAM voltage, it is just like "Auto". If your RAM's default voltage requirement is 2.0, your going to have a hard time running 1.8 without first doing some serious underclocking, or relaxing the timings. As Hueristic stated, linking is an option, but one you will have to calculate manualy as this board does not have an automatic linking feature. I still can't figure out why you would want the default 1.8 if your RAM requires 2.0

I'm going to be honest with you... You need to lap your HSF and Your CPU. It's not hard Iv'e done it with my E4300 and my Q6600. Lastly and what you need to understand is that your computer WASN'T stable at 1.44v because your multiplier was dropped to 6X. Without Speedstep, your truely going to find your CPU's maximum stable overclock. It's not easy, if it were everyone would do this. Take your time, record settings that work and their temps, and build from there. Good luck

Thanks for the advise.. but what i dont understood is the "wasnt stable" before.. it passed orthos certainly and was a bit cooler .. whats the difference with now with speedstep and C1E dissabled? Im not doubting it.. its that i simply dont know

that was very helpful, but as for the reason its because i dont want to run it at 1.8, but i would know exactly what to add to get it to run at exactly 2.0, but as for the system auto setting it, its not setting it at 2.0 its setting it at 1.97, is this fine and i should just leave it... or what?
