I was thinking the same thing. I'm surprised it hasn't died yet.

1.72!!!!!!!!!!!!!!!!!

Are you mental?

Btw, I almost forgot about this thread.

I am now able to run 3.5Ghz on this 680iLT without a problem. I set the Voltage to 1.6 in the Bios and it turns out as 1.560 in the OS. Runs Small FFT's in Prime95 quite fine but I will run it for 5 hours long somewhere in the coming days.

nice work with 3.5ghz..

i havnt read the other page, who then hell put 1.72v into their CPU? you're insane. you will destroy that chip.

That seemed to work fine, I can't be bothered to test it's real stability since I hate running those voltages (didn't run for longer the the booting up, starting 3Dmark06, running it, screenshot/save and then to turn it off again... I was downstairs eating breakfast). I can basically run up to 3.3Ghz without upping the voltage any higher then 1.408. But any higher and I have to go mental. And like I'm ever going to notice the difference between 2.7Ghz and 3.57Ghz... Especially in gaming since I only have one Videocard; that is my bottleneck, not my CPU. I can still run the same FPS on Crysis with this thing clocked at 2Ghz as it would be 3Ghz, or 3.5Ghz for that matter.

yeah you will only notice that difference in benchmarking, or if you moved to an SLI setup or a much more powerful single GPU.

but yeah, NEVER have voltages that high haha. can seriously reduce the lifespan of your chip. once the damage is done, its done.

I've never attemped to overclock any of my systems because I'm a newbie, but I'd like to take a stab at it. I have the same mobo (XFX NFORCE 680i LT SLI) and CPU (Intel Quad Core Q6600). I was wondering would it be possible to overclock to 3.0ghz without changing any of the voltage settings? Would I even notice a difference from 2.4 to OC'ing to 3.0ghz?

hey buddy, welcome to OCN.

first things first, can you please go into the User CP link at top of the page, then in the left menu click EDIT SYSTEM and fill in your system specs.

makes things way easier when helping you, we can see what RAM you have, GPU...all that.

3ghz should be reachable without voltage increase...it can depend on your actual batch of CPU, board, everything. best thing to do is leave the voltage on auto and adjust the FSB to 1333mhz (333 x 9 = 3.0ghz..pretty much).

then take note of the Vcore level your board sets automatically. if its above say...1.35v, chances are your board is putting in more volts than required. you SHOULDNT need that many, however all chips are different.

do you have aftermarket cooling on the CPU, or the stock Intel cooler?

Thanks Its my first time trying to OC. I apologize for not entering in my system specs, I didn't realize you could under User CP. They are entered in now.

I'll list them in this post:

Intel Core 2 Quad Q6600 (Kentsfield) 2.40Ghz Socket 775 1066MHz
Ultra ChillTec CPU Cooler
XFX NForce 680i LT SLI
2X 2gb OCZ SLI PC6400 DDR2 800MHz
Corsair HX1000w PSU
BFG GeForce GTX 280 OC
Cooler Master Cosmos 1000
Enzotech SLF-1 on Southbridge
Thermalright HR-05/IFX on Northbridge
5x 120mm Scythe Slip Stream fans

Used OCZ OCZTFRZTC Freeze Thermal Extreme for thermal compound on CPU, Northbridge and Southbridge

I'd like to run Vista Ultimate x64 on my system. Haven't installed it yet. I just put everything together and booted it up once to make sure everything started. So everything in the BIOS is set at factory except for the RAM voltage which I set to 2.2. I read on a few sites that ppl were having issues with the XFX NForce 680i LT SLI mobo and they fixed it by setting the RAM voltage to 2.2. I just hope I am not one of the unlucky ones that got a lemon. Read that a lot of ppl have had DOA boards or the XFX NForce 680i LT SLI would run for a week and then died. (crossing my fingers) Which is why I replaced the stock heatsink on the Southbridge and Northbridge.

no need to apologise, all newbies forget to fill out the specs.

nice rig mate

ok, well since your new to overclocking, my first advice is DO NOT play with any voltages, unless you know exactly what they do, or you have done it before.

its good when people post their voltage levels as safe and you go ahead and copy them, but as you have read, all boards are different and therefore just be careful.

the first things first, if you want some decent overclocking, you will wanna flash your motherboards BIOS to the P31 if you can find it. i did post it on this thread ages ago, but i dunno if its still there. if i still have it at home, i will re-host it. otherwise dig around. P32 should be fine otherwise.

the reason you want this BIOS is, it is the 680i BIOS not LT, which means for some reason more compatibility and a lot more overclocking/voltage control options, which will help later.

you also wanna ensure your ram is running a 1:1 ratio with your FSB. when you go into your board, you will see something something called the FSB and it has a QDR figure next to it. i cant remember exactly how it looks. thats your CPUs FSB, and for quads its multiplied by 4, hence QDR (quad data rate). @ stock, it will say 1066. divided by 4 = 266mhz, your FSB. with a 9x multiplier on your CPU, 266 x 9, = 2.394ghz, or 2.4ghz your stock speed.

sorry if you know all this, best to explain it all though just in case.

now, to ensure you have a 1:1 ratio with your RAM and FSB, get the actual FSB, stock 266 for the moment, then double it. that should be your ram speed, since RAM is Double Data Rate. so basically, a 1:1 ratio would mean your FSB is 266mhz, and your RAM is 532mhz.

3ghz is a pretty big leap from stock, what you should really do is increase your CPU speed in small increments. a lot of people say 5-10mhz increments, but that takes too long lol and as long as you have all voltage settings on default or auto, you cant go too far anyway. worst case scenario, your PC wont boot, and after 3 resets or so the BIOS generally resets itself back to stock.

to get 3ghz your FSB, as QDR, needs to be 1333mhz with your multiplier set to 9x (333x9= 2.99ghz). but dont jump there just yet.

set your FSB to 1156mhz, which = 2.6ghz. 200mhz is a pretty big jump first go, but from stock, seriously, its not that bad. you should manage that clock fine with all stock voltages.

then from there, i usually go up in at least 30mhz increments. to work it out, say you have 2.7ghz.

2700mhz divide by 9 (your multiplier) = 300mhz, your FSB. 300mhz x 4 (your Quad Data Rate) = 1200mhz, your FSB QDR, which you enter into the motherboard settings.

give it a go and let us know.

also, before you start, right down all the stock voltage levels for your CPU (Vcore), your South Bridge (SB or MCH), your North Bridge, cant remember what the BIOS calls it, stock is nearly always 1.35v, and your CPU VTT.

from memory, stock volts should be 1.5v for the South Bridge, 1,35v for the North Bridge, 1.26v or 1.27v for the Vcore and 1.2v for the CPU VTT.

dont touch those yet, just take note, and watch to see if they increase during your overclocking. if they do, stop, record what levels they got too @ what clock speeds you set, and come back to us.
