Intel QX9650 overclocking thread

Post your overclocking results voltage etc used for your 24/7 clock aswell as your benching clock . All forms of cooling are welcome. Please include prime , cpuz , benching screen shots and FPO/batch numbers when possible. I will add mine soon I'm still tweaking at 4.0ghz

[giorgos th.]

fpo?

 

[giorgos th.]

the batch number of your processor...its in the big sticker on the box

 

[trt740]

having a bit of trouble getting stable at 4.0ghz 12x333 at 1.296v is priming now any advice.

 

[Solaris17]

1.35v

 

[hat]

That's a huge step in voltage dude.
Do what the E8400 people do. 1.31-1.32 volts in the BIOS. Should be good.

 

[Solaris17]

i didnt kow you guys could spep voltage in .01 incriments. i said 1.35 because mine goes up .15v and that close to 1.3 wont be enough at 1.3

I run my e8400 @ 4.5Ghz with 1.63750 vcore with x9 multi / 2000FSB / 1.4 volts to FSB REMEMBER TO CHANGE THE Voltage on the FSB NOT JUST THE DAMN CPU CORE!

You got one too???

Ahh man to go Q6600 or stay up with the crowd QX9650.....what to do, what to do.

hmm, i would say go q6600, you can get some great results, but if you have the money and the love for overclocking - go qx all day.

I have everything but the money

that article has merit, but think of it this way - how long have you owned the same proc for 4 years as your main rig?? You might retire it to a server, on a LAN party rig, or a family computer or something - then you drop the clocks some anyways, and the article does clearly say that improved cooling helps, and the prolonged esposure just makes the chip need more voltage. My average life for a proc is 1.5 years. In that time I like to push it to the max, run it 24/7, then move on, put it in another computer at a great price to someone and move on.

 

[trt740]

okay I'm stable now had to up the nothbridge and FSB voltage slightly.

 

[giorgos th.]

i give 1.344Vcore for 4ghz - 24/7 with air cooling.
4.7 max pi 1m for now and 5470mhz for 3d benching under cascade cooling.

Ahhh, thank for this thread Tom. Will come in handy in the next couple of days (my baby is due in today. I'm dying of anticipation. )

Man this will be a busy weekend for me. This cpu, my Transcend are due back from rma, my pump is due in for my gpu loop, and I have a new monitor on the way, and I have to work on top of that. lol. Good times, good times.

these chip are hot under load similar to Xeon 3000 series

Similar to the Xeon 3000 series? My x3220 is the coolest running chip I've ever owned. Congrats on the QX9650 though. Looks like a sweet chip!

i envy you, that does sound like so much fun!

 

[asb2106]

OHH sweet, TRT - you went with a qx! Nice choice! I would love to do so myself, just cannot spend the money on it right now. Man I wish I could run a quad @ 4ghz and only 1.32 volts My q6600 takes 1.65 volts to get there, and there is no guarenteed of stability

 

[mandelore]

this is an old screeny i took from the superpi thread. gonna try with much higher fsb shortly

Well what I mean is put say 1.40v after voltage droop, through your x3220. Remember I owned two x3210, one that did 500Fsb and I also owned a X3220 and two Q6600's, so yes because the of the extra voltage the X3000 series uses it does run slightly hotter and gets worse near 1.4v+ than a Q6600. Now in the case of the Qx9650 at 1.40v, because it has more on chip memory and runs at 35watts more than a Q6600 and 30 watts more than the X3000 series it gets alot hotter, yet it runs better than a Q6600 at lower core voltage just as the X3220 does. Hope thats clear what I said up.

Also my chip runs super stable 24/7 at 10x 395 or 3.95ghz but the minute you add 5 Mhz the needed voltages jumps up a bunch. I'm trying to figure out now if it's my ram running at near DDR1200 causing the problem (DDR2 1200 in these P35 boards seems to cause stability trouble during higher overclocking) or is my heatsink getting over whelmed and making my chip unstable. My chip even at very low voltage will prime for around 1.5 hours but one core fails, it is usable in games and everyday computing, dvd burning etc all the way up to 4.4ghz . It will even prime95 blend all day long stable but small FFT /FPU's will only run for a few hours and fail. Unless I bump the voltage to 1.328v to 1.36v, anything over 1.4v starts to overwhelm my Cpu cooler during prime small FPUs touching 70c. maybe I just have a under acheiving chip or my motherboard doesn't overclock it well. I'm working on it but it appears when I drop my ram I get alot more stable. Still even at 3.95 my video game performance has jumped big time.


Hey guys anyone who has a Qx9650 and is getting different results feel free to post them and refute anything that is different than what my perception here is.

mandelore can you post your 24/7 clock.

 

[trog100]

u might find u have to up the voltage slightly for real 24/7 stability.. where my e8400 has ended up under load at 4 gig after a few weeks running.. ..

i dont think the chips run hot.. simply read hot..

trog

Very nice but man do these chips run alot hotter under load than the dual cores they idle really cool but loads a different story, atleast with my chip it is. Also a program Paul turned me on to stresses Cpus alot more than prime, Occt when it running at max you almost cannot use the computer. Unlike prime where you can surf the web etc..
