Retail Q9650 Overclocking Thread

[zsamz_]

790i need alot more juice to be stable 1.48 for same cpu same speed @ 1.38-1.4
my first q9650 wasnt stable @ 4.0 with 1.46v on 790i but it was @ 1.33 with ud3r

Striker Extreme is 680i, 4.5GHz with a quad will never happen on it with air-cooling. I used the Striker in my main rig for a year, it's a nice board but almost every P45 will kill it in regards to overclocking and performance.

OK well i don't want to get another board other wise i would just upgrade her to an i7, but if you guys could help me get started with overclocking that would be greati want to get it atleast to 4.0 and then see if i can go higher. What steps did i need to take to get started on overclocking it. What would i need to change, where should i start. i am not sure what setting i should adjust or anything, if u all could help me get started. Also tell me at what rate should i slowly move up at, where the limit is, that i should stop at, and what to look for that would really help thank you

Thank you all for the help.
my system is water cooled

Hello guys, I've swapped my 1.3 vid q9650 with 1.2 vid q9650 and I liked the lower voltages it needs for the same clocks. But this 1.2 vid chip is hotter than my old one. I've successfully ran LinX at 4400Mhz ~1.4V but it fails in prime95 x64 small fft with FATAL ERROR: Final result was xxxxx instead xxxxx.....
I've tried raising vcore/adjusting CPU GTL Reference Voltage/raising VTT but without success. I've made successful prime95 x64 small fft run with lower multiplier so memory and chipset have to be stable at this FSB(489).

Hi, I consider to buy one Q9650 because of bad company are taking the advantage of 4 cores. I found one with batch: L946b997, has someone tried this batch ? I will be happy if it will be stable 24/7 with low voltage with 4.0ghz.

[Hoss331]

It will probably do 4ghz just fine but it may not be at low voltage. I dont have any experience with that batch but from what ive seen the newer L9xx batchs dont clock as well as the older L8xxs.

[gergregg]

Core 3 sucks and requires major vcore for stability.

Wow, long time since I've been here. I see Sergio and don don still hanging around in here huh... Exiting.

Anyways I've got some cash saved up and I plan to get rid of my SLI 260's and snag a new Fermi card, either the GTX 480, or a 5870 depending on Fermi performance, once I do I'll no longer need this SLI 750i junker board I've got... so I'm wondering, the Q9650 is still a badass chip and I'm positive mine can go higher with a EP45 board.. but is it worth it to remove all this and get the new Motherboard, or should I just move to i7. i mean I don't really need it...

Basically I'm thinking of getting a Fermi card or 5870, then switching to the UD3P, and i might keep my current ram, or get something better. and try moving higher for a 24/7 clock on this thing. it works perfect for my now, I don't really need anything to much more.. but sometimes when I'm doing to much like encoding a Movie and playing Bad company 2, both CPU intensive I'll occasionally get a freeze, it's probably my 750i n oc.. I'd like to know it's 100% stable with a UD3P that will be much easier to achieve.

I have been following this thread for a while, since I bought my first Q9650 almost a year and a half ago. I just recently sold my 1.25 VID chip for a 1.1875 VID and the difference in temperatures is unreal. Also the 1.1875 chip has core temps all over the place. Core 1 is the hottest always, Core 2 is by far the coolest running core by as much as 9C, and the other two are consistent with each other.

I am getting higher temps and a lower overall overclock (9X460 @1.28 cpuz 74C only one core vs. 8.5X500 @ 1.376 cpuz 67C) due to the fact I am air cooling. I have a lapped TRUE w/ a San Ace 109R, and I think that I am going to need water to go any further.

Just wanted to say thanks for such a great resource (NapalmV5, Andressergio, Hoss, Radaja)

The Q9650 is still a kickass CPU. If you don't yet need 8 threaded ability, I'd grab a second hand UD3P, some nice Gkill Pi 9600's and have some fun. You should be able to get 4.2 - 4.5 depending on your chip, which will give you considerable power for less than a platform upgrade.

Now you have a low VID chip, you will need better cooling for sure. Good excuse to move to water cooling, that will really give you some headroom.

thanks mate such low vid to enjoy them at its best u need water but they do great at low volts

+1 for that

Hi all,

I found a sort of a bug in prime or in the CPU.....
When i stress test my CPU in prime95 it always crashes at exactly the same temprature. when it turns to 74C on core 1 then u see a dip in the tempreture it goes to 65 and then again to 74 and then worker 1 stops and the temp drops again. it doesn't matter how much vcore i give its always at the same temprature with the same error.

Error: FATAL ERROR: Final result was 48FCCFE6, expected: 26C78657.

I think this is a safety feature from intel. but its verry stupid for me cause i cant stress it to know if its stable...
My Q9550 @ 4.25 GHz i can stress it @ 1.248 volts (vid 1.1375) and @ 1.264 volts and @ 1.280 volts every time the same error at the same time (when the first core hits 74C this is the warmest core)
I know that its stable enough for me cause i can play all my games without crashes (including GTA4)

Greetings
MrDucky

guys, if I got cores 0 and 1 going exactly the same speed thru P95 Blend, while cores 2 and 3 are very different in speed (both slower....with 2.40B I could have one VERY fast, then cores 0+1 same speed, finally last core sloow)

What to change? I remember having nvidia chipset 750i SLI FTW, it had TWO GTLVREF (CPU REF), but no MCH REF....

advise me plz.

F9 BIOS + 2.50A is my new find.

I plan to get rid of my SLI 260's and snag a new Fermi card, either the GTX 480, or a 5870 depending on Fermi performance

Plz, SLI GTX260 equals GTX480. I found Corei7 @ 5.5GHz + GTX480 @ LN2...guess what, my 4.2GHz Q9650 and GTX260SLI beat it in Vantage....5.5GHz vs 4.2GHz Q9650 does NADA for FPS. Heat...GTX480 is a hot one.
I'll post a link to my comparison post at techpowerup - http://forums.techpowerup.com/showpo...postcount=1792

xguntherc, you already have a kickass PC and I don't think it's worth it to get a more expensive 775 motherboard for just a few hundred MHz more on the CPU. I fell into the trap of changing one or two components just to get and extra 200MHz here and there, and the resulting 4.3GHz I got from my Q9650 looked nice in my sig but didn't look so good in my bank statement, especially after I bought the memory, the TRUE, and the case fans I needed to go with it.

My advice: IF you upgrade at all (which I don't think you should), upgrade to X58 and keep your GTX260 SLI. I'd KILL for GTX260 SLI at this time but I just don't have the £/$ for it.

Best option is to take your OC down a couple of notches to 3.8GHz and you should easily solve your freeze problems without affecting performance noticeably, and without spending anything at all.

my old Q9650 VID 1.25




that was not prime stable, just 2D stable. I was able to run superpi 1M and thats all I really tried. It was on air as well, lapped TRUE with a single San Ace 109R, definitely too hot to prime or burntest.


here is my new Q9650, VID 1.1875



it does well at low volts but anything more than that will burst into flames

I am deciding on what parts I want for my loop, and I am thinking EK Supreme HF, dual DDC with XSPC dual top, 7/16" ID tubing with 1/2 fittings of some sort (bitspower), GTX 240 radiator to fit inside my CM690.

Can anyone suggest some quality fittings?

[Hoss331]

l0ud_sil3nc3, unless your dead set on keeping the rad inside your case I think a bigger rad would probably benefit you more than the dual pump setup.



On a side note I toyed around with wprime the other night and got a new best. I think efficiency can be better but so far so good.

honestly I have been thinking about stripping everything out of the case, and using the motherboard box, or maybe even using this case and getting a triple 120. You think a triple would be necessary even if it was a single loop cooling only the cpu?

WOW very nice wprime run, 5 Ghz is very impressive

what is the VID of your chip?

[l0ud_sil3nc3]

did this about an hour ago, not prime stable yet due to heat issues, however not bad for a single card as well

[In-Fluence]

Nice time Hoss! So is that on phase then? I'm getting my EP45-Extreme either today or tomorrow, so I'll see how it fares on this chip. I'm going to try for a ~5GHz SPI run, but I fear my PI's limit will not take me beyond 1296 like I managed with the 1Gb reapers.
Do you get a big difference in times with 2x1gb vs 2x2gb?

Very impressive for water, solid board too holding 560 FSB.

its hard on 2x2 influence...

this is mine not tuning OS too lazy to do that just shot it, its at 9,5 multi

Insane CPU mate, nice work. Have to see what it can do on the new board when you get it all together.
