I cant seem to get q6600 stable at 3 ghz.....

[Romstar]

I got my q6600 set to 310x9 and am at 2.8 ghz. I would like to reach 3 but everytime i raise the fsb(I have to raise voltages a little too) it starts up and runs fine but when I run a game after about 15 minutes it just shuts off and restarts or so. Sometimes sooner sometimes longer.

 

[skyguy]

CPU Temps? vDIMM setting? vCore setting? Mobo?

 

[Romstar]

it was at 1.35 V core when I had it at 3ghz(I downclocked it to 2.8). Speedfan read 46(but went to 47 one time) when i was running orthos at full load. It was like 39 idle in speedfan. My mobo is a badaxe2 by intel and I dont know the Vdimm or what it is or where I could find it.

 

[Romstar]

btw I set my fsb voltage too 1.25 if that helps

 

[skyguy]

Sounds like vCore may have to be a bit higher than 1.35v. And vDIMM may have to bump up +0.1 or +0.2v as well, depending on what your RAM's specs/rating/etc is.

If it only happens 15mins into a game it could be overheating. mine shuts itself down when ti gets to a certain point in degrees which ive now configured it not to get too.

 

[Romstar]

I highly doubt it is over heating due to the fact that I got the thermalright heatsink with a 90 cfm 120 mm fan attached to it and speedfan reads 47 C max at full load.

 

[Romstar]

well I just oced again to 3 ghz and i ran orthos and got an error after 5 minutes. and Speedfan reached 51 C .

 

[skyguy]

Unstable overclock. 99% sure. Probably vcore needs to be increased. Could be vdimm, hard to say without knowing RAM specs and settings though.

 

[Ogdin]

Definitely sounds like more volts required.

 

[Hatman]

If he managed to get to 2.8gig then his ram should be able to get to 3gig.

Sounds just like the simple not enough voltage problem.

 

[Romstar]

ram is pny 8500 5-5-5-15
cpu temp in speedfan just hit up to 58 which is the highest its ever been and orthos ran good for 7 minutes but gave me some fatal error crap about about hardware failure. idle temps are 39 C

 

[skyguy]

vCore man, vCore. Up the vCore.

 

[Romstar]

well I dont know if I've posted this but there is an fsb voltage setting which I have raised. Should I have raised that at all or just left it at default??

 

[skyguy]

Raising it a bit won't hurt. But it's vcore you want to increase, that's probably the culprit.

 

[jjw]

My mobo is a badaxe2 by intel and I dont know the Vdimm or what it is or where I could find it.

Pretty sure this board is not a good overclocker. I don't remember if there are 'any' memory voltage settings available.

 

[Romstar]

well I raised the Vcore and it is running smoothly now but my only concer now is temps. At full load I am getting 58-59 C in Speedfan but orthos has been running perfect for about an hour so all is good as long as it doesnt fry lol.

 

[skyguy]

Welcome to Overclocking........the perennial frustration of finding the perfect balance between speed and high temps

 

[Romstar]

is 59 in speedfan too high? because I have been told to not pass 55 lol.

 

[Doctahg]

Forget speedfan...you need Coretemp or TAT or Everest. Then you'll get the real(as you can get w/o a probe) temps of each cores.
Right now, with my E6600 at 3.48mhz..Nvmonitor says 34C..same as speedfan will...but Core temp gives me 37-39. Your cores are absolutely alot hotter than you think.
My cpu is at 1.325v, FSB 1.4. Mobo at 1.5
I am using the Enzotech Ultra X by the way. Worked much better than the TR 120 Ultra...

That's in an Evga Nf68A1 mobo..

 

[Romstar]

TAT doesnt work in vista 64 bit ultimate and neither does core temp and everest does work but I have no clue how to find teh damn temperatures in that program.

 

[Doctahg]

They work fine for me. I'm running Vista Ultimate. They all show almost exactly the same temps ALL the time.

 

[Romstar]

64 bit?

 

[bydesign]

The temps show up in the system tray or if you open up computer and sensor icon in Everest. I run the 64bit version of Vista so I feel your pain. The number seem to be in line with Intel's TAT.

In XP I'm stable with 6600 until 3.7GHz Vista wouldn't boot unless it's around 3.6GHz and not stable over 3.4GHz. At three 3.6GHz I get all sorts of hard fault in the memory resource monitor. So I think it memory issue, just kind of interesting that XP has no problems at all.

I have one of the early E6600 and never run over 1.325V up to 3.4GHz I used 1.45V to achieve 3.7Ghz. I would say up that core voltage.

 

[Doctahg]

I'm running 32 bit for now, 64 later....
I have a B step 6600. That one seems to be the best Ocer. Not sure if I need the volts I'm using, but things are stable in everything. I did get one problem at 3.6 out of the blue, but I didn't push anything after that as I just wanted to USE the CPU lol. I dropped to 3.48 and have had no problems so far.
