gigabyte ga-g1975x can someone explain the settings

[Wrangler88]

ive got the gigabyte ga-g1975x board,
just wondering with allthe overclocking settings, what voltages when changing the settings is it referncing the added voltage to?

also what are these voltage, - im used to north bridge south bridge etc, not how the bios has it listed..

pci- overvoltage control - is this the southbridge voltage control
fsb overvoltage control - is this the northbrigde voltage control
dimm overvoltage control - does it start at 1.8v's and go up from there?

sorry i sound like a noob, just wasnt sure on the naming of these voltages, im also used to picking a voltage not adding a .1 volts to stuff, specialy since im not sure what the default value im adding that .1 volt too, thanks ! hope this makes sense...

pci-overvoltage control is for the Northbridge/PCIe frequency voltage and has more voltage options than Asus P5WD2-E mobo, overvoltage is just Gigabytes terminology for overclocking above Industry accepted standards eg. JEDEC.
fsb overvoltage is just what it means - fsb voltage.
dimm overvoltage control starts at default for DDR2 (1.8v) again from JEDEC standards.

Nice to see someone else on here has this mobo too, I just got mine yesterday, but have not set it up yet (waiting on Cedarmill chip) :)

Can anyone tell me what temps their findning? I am reading 1C/33F in the BIOS and on the EasyTune-5? Also has anyone flashed the BIOS ad did it help anything?

I'm not having much luck overclocking regardless of Vcore although my chips has unlimted potential the board just doesn't seem stable all the time?

Also Hyperthreading Diable? Enable? and Why?

Luckily I measure watertemps before and after inlet/outlet respectively and the chip is running approximately 26C at 19C Ambeint.

Yea, the Easytune5 hardware monitor doesn't show CPU temp correctly. It says something like 212c. But speedfan temps are working. Mine is -30 with the Vapochill so that prolly don't help you much. I still playing with the overclock. It's best just to use Easytune5 to test the overclock then make changes to the bios after you find a working overclock. Then disable Easytune

[Liquid3D]

Thank you, but actually EasyTune-5 (which I never use for OCing, I always use BIOS) is reading temps accurately, the 0C/32C reading is being generated from within the BIOS.

I know this question isn't "sexy" for the NEWXtremesys forums, but can you tell me about HyperTheading. If it's diabled in Pentium-D's below 955X should I disable it in BIOS? Does it make a diff? has anyone verified this diff?

Thank you

[Wstinkbait]

Funny, My bios hardware monitor cpu temp is blank. Don't know what's up with that.

I don't think HT enabled would make any difference but I would disable it. Older boards would hide it if the CPU did not support it.

If you have a 930D cpu, it does not have HyperThreading by design. All the current preslers do not have it, only the 955 EE.

Thank you it's nice to know people still help each other. I guess I knew it didn't but was wondering why the board gave me the choice.

I just flashed to F2 BIOS will let you in on any changes with this one. I believe Gigabyte is working feverishly on a new BIOS, although by the temps their not sure if they have a fever, or are hyperthermic....:eek:

[IluvIntel]

I just set this board up and are having trouble getting it too post. I get a led display at bottom of Mobo flashing "l " and in the second led display something that looks like a backwards "C". My optical drive sounds like its stuck in a loop or something, I have nothing displayed on the screen.
The mobo manual does not mention this strange symbol displayed on my 2 Led lights at bottom of mobo...:stick:

Can someone who might know something about this mobo help?

Update: I have 2 PSU's setting this up and both are new, but 1 was faulty....
However, everything is OK now.

[Wstinkbait]

you prolly have a OC setting out of tolerance. I get this when I try to go over 18x multiplier. Press the blue button at the bottom of the board for 5 sec or until it goes off. then press and release the red button next to it. The MB will come on and post with default bios settings.

hmmmm, I was'nt overclocking, just setting it up for the first time and I always start of at defaults. But thanks anyway for that advice about those buttons on the bottom of mobo, the silly mobo manual gives the most brief description about what they are and leaves you scratching your head...

I am amazed at how the whole system today has been standing up to some early benchies and with everything in bios for voltage controls on auto or defaults. I have the "F3" bios installed. :woot:
As I type this I have several programs running in the background @ 4.25ghz and whole system is practically quite as a mouse... :clap:

[Wstinkbait]

F3 ! , cool I knew it was comming and have been looking forward to it. Had mine up to 5.3G when it crashed. 5.1G @1.6v seems to be stable with the 955xe on Vaporchill. Maybe new bios will show some improvements.

[Liquid3D]

Where In G.O.D.'s name do i find this F3 BIOS I can't seem to locate it at their site?

EDIT: found it, it's here for anyone who wants: F3 (http://america.giga-byte.com/MotherBoard/FileList/BIOS/bios_g1975x_f3.exe)

Although what concerns me is the "definition" which really says nothing except the "Xpress Recover 2 support." I know many manufacturers don't itemize every fix. I wish they would but i belive the truth might be too ugly in some cases for thweir public persona. I also wonder how times a result seemingly dervived from flashing the BIOS is simply wishful thinking?

For example think of the people whom try to overclock and have bad results, then one night they come across the "new BIOS" which lists something such as it does above, however; nothing remotely related to anything which migt coost their overclock. They try overclocking again and perhaps enable something they missed the first time, or perhaps it's more likely the ambeint temp is 19C instead of 25C as it was the first time they tried? Now they get this great overclock? Is it because oif the BIOS or the fact they found a new BIOS which had nothing to do with the overclock except it prompted them to try again which then allowed one of more of the contributing factors above to give a different result?

This is also known as the Philosophy of Causality, that the overclock you obtain is not necessarily the result of some rendom event but that the event was inevitable based on a series of events which came A priori

[Wstinkbait]

I can't tell any difference, My CPU temp is blank in the bios but Speedfan reads it correctly. on cold start (completly off for hours) system will boot to 5.1G (18x,288FSB, 1.7v) it will run stable for hours, but overnight the system crashs and will not post, Error 26 (internal clock Gen) Set defaults and It's good to go. I'm thinking the NB is getting too hot. The heat sink is hot enough to burn you. I'm concidering Water Cooling the NB or maybe even TEC. I'm currently working on pelting the Crossfire cards.

I have trouble booting at 3:5 with 4 x 512mb sticks, even if the SPD are at default.
My board only likes 1:1, which is of course the most efficient but would be nice to experiment with different ratio.

How are the rest of you finding the Vcore consistency when O/C ?

[Wrangler88]

teh vcore of this board SUCKS with a dual core proc my intel 930 i can only get to overclock to 3.75, itll go to 3.82 but i dont feel its 100% stable, my vcore voltages are all over the place, i really wish someone would come out with a fix for it, its a nice board other than that.... im also running a sparkle power uspple with a 12v rail w 36amps...

I'm avoiding dual core overclocking partly because of that reason, too much juice needed for a good overclock.
I mean 65nm fab has definately improved things compared to 8xx series but still room for improvement with power consumption.

I can get full 100% cpu load all day like about 16 hours at 4.67ghz from 3.2ghz default and so far extremely stable with some 40 processes running - all this with cheap cpu air cooler and system enclosed in a case. But only have 1.3v max for load according to CPU-Z v1.32. Good for single core without Vmod yet !

Anyone with this mobo tried running SuperPi_mod1.4 32mb run when overclocked ?

I can do 1Mb and 8Mb runs, but 32Mb after initial first calculation, get "rounding error" message from SuperPi. This is at 4.93ghz - 1:1.

Suggestions ? :)

Another thing, what the hell does "i-Lock" do or not do from bios ?. I have "enabled" or disabled" as only choices. It would be nice if mobo manuals explained esoteric settings a little better.
