Is this safe? q9550 clocking

Seeing you're under water.. OC the easy way. Push your volts up to 1.35v and save your BIOS settings. Then, reboot and go in to your BIOS again, and up your FSB by about 50 for the first time I'd say, then try boot in to Windows.. if it does, go back and add another 25 - 50 on, and so on and so forth.. though be careful as temperatures rise on a Quad quite quickly due to all the extra power they use. Keep going until you can't get a stable boot in to Windows, then knock off 10FSB and see if you got a stable boot and stable in Windows, then you're done :)

(the NOOBS way by the way ;))
 
Thank you TheMadDutchDude. I tried last night and got to boot at 3.6 but tried to go higher with no success. I left it then because it was late so I will try your method today. Noob method or not I didn't know it and usually try to do all the settings at once, which is probably why it didnt work.

I read the overclocking thread awhile back, printed instructions and got my other chip (Q9450) to run stable at 3.52 for months on that same board. Now I seem to have no success at all with the Q9550.
 
This is weird- No display after overclock?

When my oc failed last night I turned the rig off completely and left it till I had more time. Today it booted up with an oc of 3.74 no probs, except that cpuz reported my core voltage at 1.57 which must be way too high.

Following TheMadDutchDude's advice I dropped the voltage to 1.35, saved the settings and rebooted. The rig appeared to be booting and showed hdd activity but I had a blank monitor? Seeing as I appeared to be stuck in a boot loop I rebooted without changing anything and this time it booted up and the monitor started properly and showed me at 3.74gb oc and cpuz reported 1.347.

How can I lose the display when I oc? The Geforce 8800GTX card is set to 100mhz which I believe is normal, so I am not oc'ing the graphics card with the cpu and it failing? I run a Corsair HX620 psu so I doubt it's that. Does anyone have any idea whats going on? It could be that I am getting a decent oc but not being able to see it as the monitor display drops out. It is not the first time this has happened either so for a time this stopped me trying to oc. :confused:
 
You're under the 1.45V Voltage and the 72.4C temperature mark. (That's what intel themselves state are the max safe voltage and temperature) so you're a-okay. ;)
 
This black screen is most likely due to you having hit the FSB on either the CPU or the motherboard, I get that when I try to boot up at anything above 438FSB, even with 1.6v through my chip and 1.45v on the NB. I think it is the CPU due to my mate being able to boot up at 500FSB on his Q6600.

The only thing you can do now, is keep trying, give up after about five goes, up some of your VTT voltages and that lot, see what kind of result you can pull. Or try 1.4v through the CPU and see what that gives you.

Best of luck with this, don't try if you don't want to burn out anything though I think you should be alright.

The best thing in these situations is to keep your side of your case unscrewed (or off) so that you can reset the BIOS ASAP :)
 
Thanks for the advice.

I got mine running stable at 3.51 and at 1.35v under stress temp was about 35c. Not the best overclock but I was happy enough with it.

I installed Nero 9 yesterday after using a clean up program to get rid of the remnants of Nero 8. Rebooted and got BSOD several times, even at stock optimized settings! Bloody computers, will have another go at getting it back up tomorrow when I have more time. I have no idea why that happened because it shouldn't have made any difference?

All part of the learning curve I suppose...
 
Can you manage to read any of the message at all? Maybe it is a memory error, I know Vista doesn't like me OCing my memory at all. Even at stock voltage, stock speed and stock timings (C4) it won't boot.. just BSODs all the time which is very annoying. Maybe one of your sticks of memory is faulty and therefore letting you down?

What motherboard are you using to try and OC this Quad?
