[Praz]

but does it or not has the LLC like loadline calibration? or tell me how much is the vdrop

Yes it does.

[Praz]

The strange things is that if i leave the strap menu to AUTO and go from 266fsb*9 to 355*9 (meaning that the memory will go to 1066Mhz) the system start successfully without touching any NB-SB-VTT voice.

On auto the strap/divider is changing when FSB is scaled.

hey guys im havin some problem trying to get my Q6600 stable here.
does this cpu really require more then 1.45 for it to be stable 400x9?

[japanese]

no it doesnt mine with cpu vid 1.2850 i do it stable with 1.432

[AKHandyman]

Got my X38 up and running real COOL like ... just now really getting into this mobo and so far I like what I see ... this is my test bench and I just put a little ole AMD 60mm fan on NB heatsink and a 70mm aluminum on the backplate heatsink so that the air blows through and over the RAM temps are WAY LOW ... (notice window open and temp outside right now is -10F )



As you can see I am just starting out on my overclock adventure, but hope to achieve some decent/stable OCs so that I can do some gaming in the near future ...

[SNiiPE_DoGG]

nice wait till you boost up those voltages on the chipset, you'll wish you had an 80mm (once you close the window that is)

be sure your cpu vtt is 1.6 in bios and set the the GTL ref to 110/109 for the cpu cores, use these charts to find the gtl for your NB: http://www.edgeofstability.com/artic...fault_gtl.html

[lazy]

so the vtt needs to be that high even for a 400x9 setup and not a 450x8?
figured since its less fsb i can run it with less vtt voltage

[OnDborder]

AKHandyman, what is that heatpipe used for, coming out from under the mb, on the right side of the photo?
I like your cooling system(window open with a foot of snow)

[Ace-a-Rue]

Great info Ace, thanks! (FWIW, Maximus Extreme requires about the same NB and VTT voltages as you are using for quad core stability at 450+ fsb.)

What are you using for gtl reference settings at 450 fsb on the yorkfield?

right now i am using:

CPU GTL 1/3 REF VOLT = 122
CPU GTL 0/2 REF VOLT = 122
NB GTL REF VOLT = 124

[Ace-a-Rue]

nice work ace
so you likin the board as much as me?

it's growing on me!

[Ace-a-Rue]

Nice OC Ace-a-Rue and it appears it takes a lot to get 4.0-4.5ghz out of a
QX9650. I am just hoping the lower Yorks QX9450 or QX9550 can do 4.0 really well with low volts on this mobo.

i found up to 4 ghz (1000 mhz increase), i only needed 1.28v for actual vcore (1.15v is default set by this board)...the last 400-500 mhz required a large increase in vcore.

[AKHandyman]

nice wait till you boost up those voltages on the chipset, you'll wish you had an 80mm (once you close the window that is)

Ha ... I have another nicer fan on the way, but this 'll do until then, and Sniipe, what do you recommend I start out with on the volts for my E6850? I was hoping there was a BIOs template for this board w/E6850 ... I've done some easy OC'ing, but this BIOS does have a lot more than I am used to ...

I've tried 412x9 for 3.7GHz, but it always fails. I've upped all the voltages and still I can't get it stable.

I'll have 3DMark scores for the HD2900Pro at these settings later.

[AKHandyman]

That is the backplate that comes with the Thermalright IFX-14 ... it is actually sandwiched between the back of the mobo and the backplate bracket under where the CPU sits ... I guess it helps cool the CPU as well ... so far I haven't seen any temps on either core go over 50C (I am actually doing prime right now with a tweak to find some stable voltage for the NB ... )

What brand of RAM are you using? You know, I had a similar problem with my DFI Inf 975 board where I couldn't go past 400x9 without a good prime run making it crash ... I just kind of let it go as it is my everyday 24/7 rig, but this baby I want to really mess with and see what I can do ...

you are fustrating yourself over WHAT!?...being OCCT or P95 stable!...if you are not folding or playing heavy cpu demanding games, you are wasting electrical energy and time...it proves nothing to me...use the wPrime bench...if you hack that you are fairly stable....if anything happens after proving wPrime is valid then it is a memory timing issue.

stable is an elusive word...each of us have different definitions!...i say stable is: what ever you do and your OS doesn't freeze; get BSOD; programs close out on their own; random reboots or games drop back to your desktop.

[zanzabar]

dose the default fsb changer actually work on this board, ide be interested in just getting a higher default clock and working from there, like taking an e6850 and bumping it from 333-400 default and then getting started


and is there any way to lock the strap on the board or could that default fsb limit them

if you mean only increasing your FSB and nothing else, "Yes!"

right now i am using:

Thanks! Looking forward to trying this board out.

im having the same problem with mine also, although ive tried up to 1.47 volts for 400x9 setup

And yes i will be running wcg on this when im not personally on it so i need something stable..

I just got a pos Q6600 it pisses me off

[AKHandyman]

Well, after tweaking a bit with some of the voltages, and running a bit of Prime95 for a few hours, I think I have at least a good starting point ... thanks guys ... hope to post a few screenies of solid/stable work ...

[zsamz_]

here is a bios template for e6850
i'm sure volts can be reduced but that for later
can do either do 1000mhz or 1200mhz 5-5-5-15

cant go higher than 500fsb need more time n new bios

[AKHandyman]

Here is my first memory bench ... not too bad for a beginner ... but I know I have a long way to go before I can become an Xtreme Overclocker ...

[johnp1983]

set gtl settings 68% to 70% of voltage settings
on auto it will be set @ 67% its too low
cpu vtt must be set slightly higher than cpu v
improper gtl setting will give you many problems
gimme your voltage settings i'll give you gtl settings
btw i'm also new to dfi lol

Hello zsamz, maybe the problem can be found in the gtl settings. I leave it on "disabled".
I was trying two type of config: one with the vcore at 1.42 that I use for 425*8, and another with the vcore at 1.47 for the 450*8.

At this point I don't know how to set the memory strap because everytime i move it the mobo doesn't start on the next boot... even if i try a 267*9 with 200\800 (as example).

By the way, can you give me some trick about the NB e SB voltages? What is the maximum vcore that I can give to them? Are they involved with my faulty boot?

Thank you for your help!

On auto the strap/divider is changing when FSB is scaled.

Mmmh, so what can I do? Maybe I can try first with the settings reported zsamz?

Bye e thank you!
