[First Look] DFI 680i LT NF-680i LT SLI (56K Warning~~~)

[Wizzard005]

My instinct is that you need way more vCore than 1.425 for 3.8GHz. Also, at those kind of FSB, you will need to tweak GTL. You very well may have hit a wall at that FSB/MHz (I don't know anyone that's got a quad running at that speed on this board) but you won't know til you give it max juice and tweak GTL. Welcome to the fun that is OC'ing a DFI board!

Here's my experience with running at that speed... I had to max every voltage and it still wasn't stable... http://virtualrain.blogspot.com/2007...-at-38ghz.html

What is GTL? I have a E66000 not a Q6600 . I am able to start booting at 4.0Ghz however it blue screens, so i though the cpu need more vcore. I have it at 1.6 atm and dont know how to make it go higher?

My settings now are 1.6vcore @ 3.84Ghz @ -10c on ideal and about 4c on load.

I would like to get a stable 4.0Ghz with this cpu at least. I would very much it it to be prime stable, but if i run prime now it will simply hang after a few mins.

Should i have to mess with any of the other volts? SB core? or whatever? PCI 100Mhz ?

any info would be great!

Also anyoe know the limits on the NB vcore? What is too much? I have noticed if i put it up too much the system will hang, however too low the system wont boot!

ok,
1. Leave GTL alone, CPU VID SPECIAL ADD will take you higher than 1.60v I don't have the table but I just increase the values 2 at a time reboot and check volts until I get to the desire volts (be careful of frying your cpu)

2. Increase your NB volts to 1.48v SB volts to 1.60v and your LDT 1.40V.

3. For now don't worry about overclocking you pci bus.

Try this and report back with exact behavior on your system

i was able to boot once into windows @ 4.02Ghz CPU at 1.6 and NB was 1.5something... Since then i haven't been able to boot with those settings.

Even at 3.8Ghz its not prime stable, after 5 -10mins the system will hang. Not sure if its the cpu or something else that needs more or less volts.

Hey guys, I got my new CPU today, I have a Q6600 with B3 Stepping. We tested this CPU on a intel motherboard with the same Ram and we were able to get 3.8Ghz before it got too hot for the thermaltake cooler we tested it with. So since it pasted our test on the other motherboard I figured lets put the tec on it to see what it can do on this DFI motherboard.

So far we are able to get only 75Mhz over stock????

Everything you re-boot it hangs on error code 18..

No matter what clock or vcore or NB vcore it gives the error code 18

Anyone else have any problems with the Q6600 not posting? If so you have one, please kindly share your settings..

Another weird problem. Using Everest cpu benchmark photoworks, on the dfi motherboard stock clock it gets 12000 , on the intel motherboard it gets 26000

Same ram same CPU, what is going on here? The DFI motherboard says to be the best on the market, so far it runs like a ECS!!

Any help / info would be great

This board is not as easy to setup as any other boards outthere. You are not going to slap that quad and raise FSB to xxx mhz. It is just not going to happend. You need to spend sometime with the board and read about each setting and use the trial and error method of testing.

I have read all over that this board is not the best for the quads.

Test on
M.

thanks for the input, tested ended yesterday. I ordered a P35 motherboard instead.

Its funny, my evga motherboard i got better clocks on it, this dfi is very fussy..

[Gorod]

Any one has a BIOS for QX6850 with that board ? The old 4CTST521 wont recognize CPU correctly The new N5FD723 has multi limited to x9 ...

[Gorod]

sigh ... just found out that cant realy use 4CTST521 BIOS , even at stock clocks it eventualy drops multi to x6 . It's been almost a month since QX6850 hit Retail and still no BIOS to support that CPU ? Not even at least a beta ? Cmon DFI ... why are you doing this to us ?

1) 4CTST521 - serious FSB overclock issues , multi drops to x6

2) N5FD723 - theres no unlocked multi , x6 multi drop issues under question ... still testing .

[Wiggy McShades]

so is the 723 the best bios for the Q6600 G0 stepping? or is that still 521?

[The Nemesis]

Personally this board is not good for overclocking quads yet. The 521 bios is the best but once things heat up, the multipiler drops to 6. I'm waiting on thermalrights new pwm cooler or I'm gonna have to break down and add water cooling to 'em. The 723 bios flat out suxed for me. I could get nowhere near the overclocks I got with the 521 bios.

dfi boards are always fussy..only like certain rams...etc.

same reason i am sticking with what i have now...it clocks well

what mobo did you go with?

[X.T.R.E.M.E_ICE]

Will this board do 600FSB with quadcore

[thorgal]

Will this board do 600FSB with quadcore

lol, 'course not Not even with a dual core

[X.T.R.E.M.E_ICE]

lol, 'course not Not even with a dual core

sorry i posted in the wrong DFI thread. i meant to post in the P35 1.

[killingspreez]

Hi,
during the bios-flash back to 521 my system crashed (right in the middle of programming the bootblock).
now i need someone i can send my bios chip to and who can hotflash a new bios on my chip.
somebody from germany or europe in general would be great!
please contact me, if you are able to help!

of course i'll pay u for it

What BIOS is best for this board for C2Ds?

What BIOS is best for this board for C2Ds?

I'm using 0521 but someone here told me that he liked the 723 better (got better results) I think I will try it(0723) this weekend.
I have read over at DFI forums that some people gotten error 88 after flashing bios to 0723. (reason why I'm still debating to try it)

Peace

[The Nemesis]

each time I got 88 error code I was able to bet the board to post when I switched from quad core to dual core.

[virtualrain]

each time I got 88 error code I was able to bet the board to post when I switched from quad core to dual core.

Great!... maybe DFI should ship a dual core chip with each board to help us recover from these f'd up errors.

I had to RMA mine due to an 88 error that I could not recover from.

After overclocking my friends G0 to 3.6GHz on his EVGA A1 board in just a few hours (no fuss at all), I'm very unimpressed with my DFI board experience (it took a week of fussing to get it to the same clocks).

[justin_c]

anybody have a vcore/vdroop mod for this board? i really want to pick up a evga 680i a1, its going for 199 canadian @ ncix.

[Kampfzerstorer]

Yeah this mobo is pretty busted if you ask me. Too much time for results you can get eslewhere with far less time.

[SchiuZ]

Hi all, I am trying this motherboard with a Q6600 B3, I am so noob that I can't understand witch BIOS is in the motherboard. I discovered with Everest that the BIOS date is 05/21/07 so I suppose that the BIOS is the 2CTST521 or the 4CTST521 but I really couldn't understand more.

I suppose that the 2CTST521 BIOS comes by default, but I am not sure. Please tell me:

1) How to find the exact BIOS that I have on the motherboard.
2) If I can try the new N5FD723, I read that this BIOS could be a motherboard-killer.

Thanks for help .

EDIT: I forgot to say that my motherboard is the DFI 680i LT T2RS and not the DFI 680i LT T2R .

[SchiuZ]

I wuold aslo like to know, if possibile, if there is some vDrop MOD (pencil) on this motherboard that you can do to fix the IDLE - FULL voltage difference .
