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

The quads are a lot more resiliant to voltage abuse than Wolfdale's. No more than 1.7v PLL on Wolfdale. The max I have noticed a difference is with 1.9v. And yes I have tried well over 2v.:o
 
wats a good temp to have this processor running at? i've clocked it to 3ghz and its running at 24C, so im sure i can get some more juice out of it, but dont want to up my fan speeds too much.

Ive managed to get 3.8 but as soon as i try 3.85 it starts to restart before ican get into the bios to up the voltages and by that i mean shows the bios then restarts.
 
I'm somewhat sceptical that VTT of 1.4V killed that chip, if they were that sensitive chips would be dying left, right and centre (especially when people are giving them 1.7-1.8V :o).
 
Quickie... Got my new Q9450 2 days ago. After struggling with the crappy Asus P5N-T mobo I eventually seemed to get the system stable by manually altering most of the settings in BIOS to stock speeds as the 'auto' settings just seem to have a nightmare. I haven't pushed the chip too much yet, and am now just running it at 3Ghz. It looks happy and stable at about 50-55 degrees under load after cpu testing for a couple of hours.

However, I left it on overnight and all it was doing was downloading....no great CPU stress or anything and I wake up this monrning and the PC has black screened and after rebooting I check BIOS hardware monitor and the chip is running at 70degrees. :( Me confused ;)
 
I would believe it as even at stock they show high temps, have compared this myself.
This is going on what I see, not whether the temp sensor is faulty or not.
 
my Q9450 has been running a bit hot at idle at about 50-55c ish and 70 under load during gaming. However I just took out one of my 8800GTX cards for testing, and for some reason y CPU temps have now dropped by about 10degrees. Why would having 2 cards in SLI effect the CPU temp that much?

if its all aircooled then its just the heatdump from the fans, I find that totally believable.
 
Have to say these (much hyped!) Q9xxx processors are looking pretty pathetic. Only getting around 3.5Ghz on average and at very high volts doesn't look at all good tbh.

More than happy I went with my E8400 which does 4Ghz at 1.29v. Looks like getting a Q9xxx to 4Ghz on air is all but impossible and, at 3.5Ghz, you'd need to be doing something which makes very efficient use of all four cores to actually beat the dual, i.e. rendering, encoding etc.

Think my E8400 is set to stay until Nehalem now.

well you started the thread on the 30th march, wheres it coming from, outer mongolia strapped to the back of an aging yak? :p

after manageing to scrape 3.5 prime stable from mine clicky clicky ive given up on it & sold it on. no gain or loss on the deal. "might" get a Q9550 later on in the year, there again i might not.

really wish i hadn't sold my Q6600 G0 that did 3.85 prime stable at only a meagre 1.35 vcore

you sure its not just current motherboards holding this chip back

maybe bios updates will solve the issue
 
Glad too see Intel are keeping up their high IHS quality standards
