Retail Q9650 Overclocking Thread

[nick2crete]

Running only on a Zalman 600Watt with 4*16 = 64A on the 12V rails.

Thats not the total of the Ah ..it doesnt work like that..
Mine has 20Ah on every 12v rail (4) but only 48 total..

[LOCO LAPTOP]

Hmmm, is that sarcasm or what? You have decent clocks for x48, but it's no secret that UD3P is king of the hill when it comes to 45nm quads.

Incidentally, I'm parting ways with my Q9650, UD3P, and 8GBs of G.Skills F2-7200CL4D. I've successfully primed them at 8 x 525, and 8.5 x 520. PM me if interested.

Edit: 8.5 x 520 with 8Gbs is my 24/7; just to give those interested an idea about stability.

Not sarcasm. I had nothing but problems ever since I got the Rampage until last month when I got my 5th replacement board.

This 5 GHz q9650 club.. the efforts in taming the heat this thing spits out at load.. very nice.

I have an interesting time air-cooling this chip's 4 Ghz prime95 runs.

I suppose real overclocking begins with real cooling, hunh?

As i said before I run my Q9650 at 4428mhz now (492x9) @ 1.4v on a 620w PSU which is only doing 12.03v on the 12v rail

On a rampage extreme too

Just bumped it one nudge to 1.4v from spec in sig

EDIT: From what everyone is saying in this thread it sounds like I am EXTREMELY lucky to have this clock, on this mobo, with this PSU

[InfinityG35]

After a lot of effort I got my system stable @ 4000 (445*9)

PLL = 1.50
VTT = 1.34
VCore = 1.40 (LLC disabled, load = 1.28V).

Mem @ 1068 5-5-5-18 2.1V

Rest on AUTO.

- System is prime blend 8h stable
- Linpack 50 runs stable
- Memtest 8 hour stable

However, 3Dmark06 gives an instant crash and also 3Dmark01 crashes after 2 runs.

How to overcome these errors, more MCH? MCH at auto = 1.20

Anyone have any templates I can use for getting past 3.0Ghz on my EVGA 750i FTW?

I can post at 3.6Ghz, but I keep BSOD'ing or getting core errors on OCCT.

I set my BIOS to 1600FSB and Vcore to 1.28, trying 1.3v now. Everything else on the BIOS Voltages are set to AUTO and I have my RAM synced to my FSB.

System specs:

Motherboard: EVGA 750i FTW
CPU Cooler: ZEROtherm Nirvana NV120
RAM: 4GB OCZ ReaperX
Video Cards: Nvidia GTX 260's in SLI
Monitor: Acer P243W 24"
Power Supply: Ultra X3 1000w

^ get an ep45 if you want to really oc your q9650

+1 for that

and watercooled.. thats lucky ?

if you guys want lucky.. heres lucky: http://www.xtremesystems.org/forums/...d.php?t=206237 4.8ghz - all air cooled

if id want to watercool.. 4.8ghz fully stable easy peasy

[NapalmV5]

+1 for that

sup sergio!

glad more of you have opened up to ep45-x and are taking your q9650 to new heights

Ew, nvidia chipset. I see that you have SLI, so you can't really switch to the ep45 unless your willing to remove one.

I like SLI, it does generate too much heat, but resale value of my GTX 260's are too low now.

I would get that board in a heartbeat if I didn't run SLI' but I went the gaming power route I guess.

I've upped my Vcore all the way up to 1.3125 which will be the furthest I will go, and it still fails OCCT. This makes no sense at all! I'm peaking the 70C mark too.

I just want to hit the magical 3.6Ghz.

I was able to go from 2.4Ghz to 3.0Ghz on my old Q6600 w/ upping the Vcore a notch and ran rock stable. I do the same here I Blue Screen... wtf.

[Dinho Fatal1ty®]

Nice nice nice !!!

[xguntherc]

Not sure what to tell you with that 750i there. and why is 1.31 your limit. that is stupid. When Intel says the limit for vcore is 1.36 and that is just them being EXTRA Cautious. when really we can run these Q9650's at 1.4v all day!

Also nas, I think part of your problem is that ghetto Nirvana cooler, you have one of the best s775 CPU's on the market. that was a pretty penny to buy, yet you have a $25.99 cooler on it. I'd suggest you get a TRUE, or a S-1283, or a Cooler Master V8 on that thing. and then you'll be better. OCCT fails with anything over 62c. (That was OCCT's Default when I installed it on my system). so that could be why.

my 750i was only able to take my Q6700 to 3.66 Ghz. but my 750i got my Q9650 to 3.8 Ghz my FIRST time. and 4.0 Ghz was just a few voltage clicks higher. I've done 3DMark06 runs at 4.3 Ghz also. but not stable. but then I've never went over 1.38 on vcore either.. but that is because I live in a desert and didn't have water. but now I'm running water, and I change my voltage all the time.

[xguntherc]

Also, I was wondering if everyone here on this thread would post there current 24/7 vcore for there Q9650's. Also post your Max vcore if you'd like. but what I'm looking for is a list of 24/7 vcore's that people have run, and possibly for how long. I think these Q9650's have a vcore limit close to 1.5v just like the Q6600's and just like Nehalem, since i7 recommended vcore limit is 1.5v and they are made using the same 45nm High-K chips as Yorkfield and other 45nm chips.

So ya, can you guys post your 24/7 vcore on your Q9650's please. I'll go first.

I've been running 1.33 in BIOS, 1.312v CPU-Z at 4.0 Ghz for about 7 months now.

Sorry for Double post!

[NapalmV5]

^ 24/7: believe it or not 4.6ghz on air/thermalright ifx14/ep45-extreme

and no such thing as 1.5vcore limit

[NapalmV5]

heres how fast q9650 is @ 4.6

[xguntherc]

I'm not saying 1.5v is the limit.. I'm saying that is Intel's recommended limit. These chips have NO limit. it's as high as the user wants or dares.

what is the highest 24/7 vcore you used Napalm for longer than a month or 2.. Your saying your 24/7 is 4.6 Ghz... awesome. at what vcore??

oh and nice to see you around here again. I owe my 4.3 Ghz clocks to you for ur help and good info.. Thanks Man!

[NapalmV5]

ive been running these voltages since last year

the 1.2125vider @ 1.58vcore @ bios
the 1.2500vider @ 1.60vcore @ bios

whos got the balls to run that?

so many inquire about vcore yet only so few got the balls!

[NapalmV5]

@ idle/@ bios ^

[NapalmV5]

and heres why i got to run it ~1.6vcore

video - this beast draws a whole lot of juice


sound - this beast draws a whole lot of juice


+ areca raid/2x ssd

if it wouldnt be for all that ^ no need for 1.6vcore.. 1.5 would do

[Loco23]

Absolute maximum for Core and FSB termination voltage - 1.45v. From Intel® Core™2 Extreme Processor QX9000¹ Series and Intel® Core™2 Quad Processor Q9000¹, Q9000S¹, Q8000¹ and Q8000S¹ Series Datasheet
My Q9450 worked at 1.525v very well for a few months

[NapalmV5]

my q9650s have been running @ 1.55-1.60vcore/1.60-1.66vtt on air since last year

benched my 1.2125vider @ 1.8vtt/534fsb for quite some time.. still runs it

[Loco23]

On my mobo VTT limit is 1.7v
I feel i can do more than 5004Hz, but VTT prevents me from it

[tool_462]

@ idle/@ bios ^

Curious what load temps are and what fans you have on the IFX?
