Retail Q9650 Overclocking Thread

[Utnorris]

I have the same issue with my QX9650, but since they are the same or near the same under load I don't worry about it. At first I thought it might have been the IHS was warped, but I lapped it and I still have the same issue. Oh well, as long as it OC's high and it works I am not going to worry about it right now. I can pick up a Q9650 later on around Xmas if need be. Anyway, don't worry about it as long as there are no other issues. Otherwise RMA it.

Yep the Qxxxx cpu's have some quirky sensors.

[zlojack]

From what I've seen, a lot of the 45nm chips (don't want to say all) have quirky sensors.

[Devious]

Update, 4.185Ghz with 1.264v




Unfortunately, this is my Asus maximus' limit on FSB, wont boot with 470 even when i drop the multi.

[SNiiPE_DoGG]

I know its these damn x38/x48 chipsets + quads. I cannot wait to get my p45 avenger

[xguntherc]

MY 750i has hit 467 FSB for a clock of 42.05 Ghz on mine.. Stable.

Zlojack what do you mean, (Thats the Time Pressured one) and to RMA it. are you talking about the CPU.

I have that exact batch number. I thought all were different. Mine is L822B363 with VID of 1.2500 and I've hit 4.205 ghz with it and will try for more.
is that a bad batch zlojack?? Cuz I've not heard anything like that.

[bigslappy]

Mine had a stuck sensor & i let it idle for 12 hours & starting working JUST fine after the burn in ..... Now it screamms ..................

hi I have the evga 780i q9650 and flex 2 9200 running at default ATM but looking to overclock the cpu to 4 ghz can anyone help me with bios settings I also just got 2x gtx 260 which play crysis at 1080i on max setting min fps are 37 but got all these highend parts but running stock settings want my ram running at 1200mhz 5-5-5-14 which they can do with ease and CPU at 4 ghz + pls help thanks Davidoff

[xguntherc]

getting the CPU past 3.4 Ghz will make the SLI run better. as they need faster CPU..

you can very easily get to 4.0 Ghz on these chips.. even more so with the 780i. my 750i did it no problem. I'm sure your BIOS it a little different than mine. but start by disabling Intel Speed Step and C1E in CPU Features.
Then for the overclock. Start by getting Core Temp and telling us your VID. as that will help with letting us know what voltage to set.. Also at default voltage you should be able to hit 3.6 ghz or more. just punch in the number, save and exit.

Start with doing something like this. I'd set Ram to Manual and leave it at whatever the default stock speed is. clock that later after CPU is stable.
in BIOS do this.
set cpu voltage. aka vcore to 1.3v
set cpu fsb aka FSB/VTT to 1.3 also.
set VDIMM memory voltage to whatever mfg spec's call for. usually 2.1v
then I'd add a little to the NB as thats a big part of clocking Quads this high.

with those settings you should at least be able to hit 3.8 Ghz. at and 1.3v you might even be able to hit 4.0 ghz depending on what VID you have. Mine is 1.2500 and thats the highest you can get. I can't hit 4.0 Ghz stable with anything under 1.3312v but if your VID is like 1.2000 or so then 1.3 should hit 4.0 Ghz pretty easily.

Give that a try and get back to us!

[davidoff619]

will i need to do the pencil mod or any other mod im running water cooled cpu. i had a asus p5q dlx before which killed my 9800 gx2 but had no vdroop well maybe a tiny little bit but the 780i have quite a bit so i have heard. if the mod is need can somone point me in the right direction. i will check 2moz when i go home. then i will get back to you thanks for your help and advise so far thats why i love this forum every will always try to help you the best they can. thanks everyone here.

mine shows a VID in core temp as 1.1375v @ 4050.00MHz(450.00 x 9.0) Prime 95 Blend=100% load


YaHoo !

[bigslappy]

Just thrown my L822B363 in, Pack date 8/13/08, first boot with 1.25 in bios, 1.232v in CPU-Z. Vid 1.2375. Chip has potential, definately smokes the QX9650 i had.



Not too happy with my temps, i need to give my w/c a service.



cores 3 & 4 are like 9c higher than cores 1 & 2 when idle. 1&2 seem to catch up under load though.

ya Need to burn-in the CPU in for awhile before pushing these CPU's Hard ! the sensors will take a few days to move correctly .. as u can damage them & the CPU if pushed hard too early
.. A word of warning !

my CPU sensors were wildly different the 1st 3 days i had my Q9650 & then they have settled down......the sensors are now within 4 degrees of each other
& you should use the newest RealTemp 2.79.7 it is way more dependable with the newer quads

YaHoo !

If that is tru VID it will clock very nice. but warm. Any load Shots ?

[bigslappy]

can't do SS right now off to work
temps under load 100% is 39,38,38,41 in RealTemp Prime 95 Blend @4GHz

[Jor3lBR]

I bet you have C1 or other energy saving option enable and if you don't upgrade your CoreTemp, Everest and etc it will show a lower VID also...


I had the version before 0.99.3 and my 'true' VID was 1.11v and after I updated Everest and coretemp it corrected the VID to 1.2125v.

[bigslappy]

all these CPU's(the Q9650) are great everyone is hung up on the VID # not to worry .. just don't push them hard until burned in ...

How are you guys burning them in? Only leaving on idle for 24hrs? priming? What?

[cadaveca]

An intel rep came on the forum many months ago when QX9650 first came out. He suggested slow increase in voltages, running TAT or similar, for break-in. Huge jumps in voltage aren't a good idea...even 1.25v to 1.35v is a bit much...I have followed this and even after running IBT for a week @ 90c, I've noticed absolutely no degredation, and if anything, temps have dropped a few degrees.

I just picked a a rampage extreme to try out with this 9650. I know most people say the maximus 2 formula i have atm will clock quads better, but i'm stuck at 480fsb with the maximus. Maybe i can get more with the rampage. bbl with results.

Did you try 500x8 with your Formula?

[nugzo]

Did you try 500x8 with your Formula?

Yup. And 7 and 6. It could maybe doubtfully be memory. It works fine on all of my nforce boards though at 1000mhz. Tried 4gb too didnt help

[xguntherc]

Those are great VID's. as mine is 1.2500 and I need over 1.33v to get 4.0 Ghz stable. I was worried when I saw 1.2500 but it seems like ALL of these things are clocking great.

Also Devious. I can't believe your complaining.. Thats so NOT fair. you're very very lucky to be prime stable at 4.0 Ghz with only 1.23v like that first shot you put up. I need 1.3312v to be Prime stable at 4.0 Ghz. also at 4.0 your full LOAD temps are around 45c. thats very very good for air cooling. I WISH mine were that good, and you said you were not happy with the temps. lol.

So. I lapped my Tuniq. and now my Q9650 at 4.0 Ghz idles around 34c but I've yet to replace the top 120mm fans on my case, I ordered new ones. so maybe they will help my temps.


I'm thinkin about getting the TRUE instead. as I'm still not happy with temps. Loads are around 61/55/55/55 or so. I've seen many people with same, or higher clocks get better, and lower load temps. just like devious. I know he's on less voltage but still. these temps just aren't good enough for me.. I know the true is a little better. you guys think I'd benefit from getting the TRUE.

[bigslappy]

How are you guys burning them in? Only leaving on idle for 24hrs? priming? What?

as i posted earlier I idled mine about 12 hrs , then did a Light O/C for the next 2 days off & on , then stock voltages as I primed it for an hour at a time

Think it's like a new racecar run it easy at 1st but run it thru the gears idle/load/idle/load/idle/load/idle but not balls to the walls,or Redline it , till she's broke in !

[pascalbrown]

I've been messing about with this CPU trying to get it as far as I can within reasonable voltages and this is what I reached with a vcore of 1.42 actual. These are not prime stable, but they are benchmark stable. In terms of prime stability I'm only up to 474*9 at 1.4v with all other voltages fairly low.

I was aiming for 4.5GHz with my ram at 1200MHz. Not there yet...

Drop some water on that Puppy & yer off to the Races !!!

But Really .. Yes get a True ! but also play with settings as u should be able get the Volts down & still get to stable ,, but everyone's boards/setups are different soo what one guy gets u might not , but also you are getting better O/C's than some PPl also ! ............
