***The Official Yorkfield Q9300/Q9450/Q9550 Overclocking Thread ***

lol, i aint gunna pay the inflated current prices that people are charging now, will wait 6 weeks or so, by then watercooled guys will have tried 1.55v/1.6v too, i'd be happy with an q9450 for £200 and 3.8ghz. Dont want any less though.

Regardless of how its cooled if you run a yorkfield at 1.6v 24/7 its life is still going to be drastically reduced due to electromigration.

Go kill your own processor :p
 
It's normal for new releases to appear in OEM form first as they are usually made available to system builders before the retail versions are made available to the general public.

Yes but the 9450 being on OEM when the 9300's are out on retail doesn't make sense :confused:. Didn't they all get the same release date?.

If the release date is the same (I think it is) then the 9300's on retail should be accompanied by the 9450 in retail with OEM being the first CPU's to be released to the public.
 
I have tried highish volts 1.5v, dont work, you hit a FSB wall before you run out of volts. so it dont make a lot of difference. I am at 465*7.5 using 1.296v (CPU-Z), cant go any higher stable, what ever volts I give the board or CPU
Thought I would clear that up and I have a fairly decent board in a P5E.
I reckon the cpu has much more in it (with good cooling) as they run a little hot, but current boards dont, when they have, I reckon these CPU's will be very good, when boards can run them in excess of 500fsb.
 
Er. Good example of the really messed up temp monitoring. Honestly. I don't know what to believe at all. Running Orthos small FFTs. Will take the voltage down if it's stable as is.



It's on a Noctua UH-12P.
 
Have the same problem with my Wolfdale, if a problem at all, it’s just the on die temp probes cant really be trusted anymore on these 45nm processors.
I really doubt its hitting 70C with 1.23v, one would hope not anyway.
 
Backed it down to 460FSB fluctuates in bios between 1.280 to 1.288. I actually set it to 1.3250

Currently running at 3440Mhz (430x8). I'm a bit annoyed that my chip seems to be a little voltage hungry compared to some reports. At least it's still in the safe range though. Any tips on my voltages? My core's unstable at 1.275v but seems to be stable now - I'll try to take it down tomorrow. Running a Rampage Formula/Q9450 on air. Also what should I be putting my CPU PLL at?

Just for a test put your voltages at these settings as 430FSB is poor mate, you should be getting at least 450.

FSB at least 450
PCI-E 101
CPU volts 1.4v
FSB termination 1.5v
DRAM 2.2v
NB volts 1.65v
SB auto
Over voltage control auto
 
Just had my Q9450 priming for 5 hours,i cant get it to boot at 3.6 even with 1.4v will try that when i get a new bios for my maximus.

 
That's not to shabby Deluxe1! 3400MHz Quad Penryn is nothing to sniff at, look forward to some benchies once you finished your stability testing. I wonder if those temps are correct? Seems a little bit high for 1.232vCore but I guess it depends on your cooling?
 
Hey, How do I test all four cores at once? I ran Orphus two seperate times (seperate folders) but It only tests the same two cores, My CPU at stock in AI Probe says around 26-28degress but in (RealTemp) core temp they all hanging around late 50's when testing 2 cores with blend, is this high? when idle they are about late 40's or 51ish. Is this normal?

What is the safe/stable highest temp of these cores, So I know what to aim for when OC'ing and testing.

ATLANT3AN

Using Thermalright Ultra 120 Extreme
 
I have been doing some more testing today to see how low I can get the voltages for a 460 FSB.
Here are my findings, hope this helps.

3.46ghz
FSB 460
vcore 1.30625v (bios setting) actual 1.264v
CPU PLL 1.7v
FSB termination 1.4v
NB 1.49v
SB 1.100v

Did this as I didn't want the previous auto settings giving more volts than I need.
