Seems wrong

[Addicted]

I'm a complete noob at overclocking, however i learnt that changing the FSB on my Q6600 B3 was a simple way to get it to 3Ghz.

My Spec:

Q6600 B3 @ 3Ghz / Noctua u12p

Gigabyte P35-DS4

OCZ 8GB (4x2GB) PC2-6400C5 (JUST changed today)

Ever since changing it (from Corsair XMS2 PC6400C4), the memory timings were changed to default as they used to be on 4-4-4-12 with my other mem, and now it seems my quad is much hotter than it should be, and im not sure why:

Here's a pic of my bios:

piepiepie.co.uk/pub/vcore.jpg

Surely the vCore is way too high here? yet its set to auto in bios :S

CoreTemp + others:

piepiepie.co.uk/pub/coretemp.jpg

(cannot post URL because i dont have 15 posts )

(as you can see in this pic, i have even set the ram timings back to really slow speeds just to make sure it wasnt these)

The CPU used to idle at around 30-33C, but now it's idling nearly 50C so something cant be right?

I've even reseated the heatsink today and applied new compound, but it's made bugger all difference!

I just wondered if someone could take me step by step through what bios settings should be what, so i dont knacker my system up!

Thanks alot,

i saw the pics, and the core temp pic, the frequency of the cpu is a bit weird, take a look at mine

first: put all your mobo on default (reset it if you can)

then use cpuz again, also your cpu is running at 1,9ghz and it normaly runs at 2,4 at minimum

According to that bios screen, you are putting 1.558 volts through the processor. I'm surprised its not hotter than that. Reduce your voltage NOW. You haven't got water or sub zero cooling so you are putting your CPU in serious danger.

I don't know the exact voltage it should be (obv it will vary processor to processor) but you should be looking at 1.35-1.40 at absolute most.

In addition overclocking will increase the power draw of the processor.

Set the Vcore manually.

Never, ever, leave the voltage at AUTO if you're overclocking. In fact try not to leave it at AUTO anyway.

, also your cpu is running at 1,9ghz and it normaly runs at 2,4 at minimum

the reason that the speed is 1.9 is because the multi is at 6 not 9,looks like speedstep is on

hmm, i see, i never had this problem since my mobo dont have it , anyways thanks for the info.

addicted, a normal voltage for this cpu would be 1,25 ~ 1,35 try getting it down like the guys said. or you cpu could fry

ok so all that i need to do is set the cpu voltage down to what it should be and that will make it ok?

It was running at a low voltage before, i assume because i used all 4 slots instead of just the 2 ram slots it increased for some reason.

I noticed that reading up on guides i also need to disable speed stepping and other shizzle like that. When i go into the bios, what exactly will i need to change?

See:

pcstats.com/articleimages/200711/GBTGAP35DS4_BIOS2.jpg

What do i need to set each of those to?

Sorry to be a pain in the arse!

I'm no expert, but haven't you got 1.5v OVER the already set voltage controls on the DIMM?

I thought there was one setting for DIMM voltage, and the overvolt was just to pump even more in if you're hardcore? I'm amazed that the RAM hasn't let out the magic smoke yet.

Like your highlighted CPU one should be 0. Because you set the Vcore in another page and it's already at the correct 1.35v

that's not a screenshot of mine, thats just an example screenshot of the settings i must set

sorry i was not clear!

Phew! Cripes I almost had a heart-attack.

 

[Addicted]

:]

so just set those two you said and leave the rest as auto, or..?

Phew! Cripes I almost had a heart-attack.

me too lol, anyways first try tweaking only your multiplier ( the Q6600 get 3ghz at 333mhz x 9 multi. and you dont need to touch the voltages (at least that worked for me, also i can do 3,4ghz w/o touching it but i dont like to pass 3,0ghz since were i live is pretty hot, and im using air cooling.

yea i only changed the FSB without changing the voltage on my old ram.

when i installed the new ram, because the voltage for cpu was set to auto, it felt the need to up it to nearly 1.6V,no idea why, but i've fixed that now!

also, what did you set the FSB to get it at 3.2 and 3.4? those would be nice to test!

i'm in the UK so it's not particularly warm here at any time!

hmm for an air cooled cpu, also for 24/7 OC maybe 3,2 is the barrier (at least for me since it gets pretty hot here hehe), but you could try 3,4ghz if you wished, also use prime 95 to make an stress test so you can see if the overclock is stable. good luck with the overclock mate

thanks

by the way, i take it i should not go over around 65C really?

 

[soapsupah]

hmm for an iddle cpu i wouldn't pass the 45 ~50 c, but at full 65 isnt a bad temp (depending on your cooling solution, and how much you OC'ed). also if you could, tell me the heatsink and fan you are using to cool your q6600, but i really think 3,0 ~ 3,2 ghz the max i would accept using an air cooler ( ijust dont feel good with big temps).

im on the noctua u12p with stock fan (120mm @ ~1300rpm)

just tried to set it to 3.2, failed to reboot, then rebooted itself at 2.6, so i assume i need to up the voltage?

what is the max i can realistically go to? i assume that increasing the fsb also affects the ram? so what is the real real max?

 

[soapsupah]

hmm the cooler is pretty good so the temps wont be so high, also there are some Q6600 that cant pass the 3,2ghz line (i dont have a clye why but i know some that can't, and i hope isnt your case) another tip, try setting the clock speed at the max you can before it cant reboot then go back a little until it reboots, also try tweaking your voltage a little higher (if its at 1,25 ~stock speed i supose) you could put it at 1.35 or 1.45 i dont recomend passing this line aswell, also your mobo will have a big role in OC'ing i can oc until 3,4ghz with my MSI P35 Platinum (if you can google it to see its FSB etc because i dont remember) i will take a photo of cpu Z also i hope it helps with something.

also other users could help with it since when i OC i normaly just touch the clock x multiplier, (to do a 3,4ghz i had to elevate my voltage from 1,25 to 1.40).

ok thanks, ill have a look at it

could it be that either my quad wont go over 3ghz, or that i havent set the voltage high enough which is causing it to reboot?

i assume it is going to be both, but i'll do the incremental steps anywya, and see how far i can get!

p.s.: here's the link to my mobo specs:

i think i have one of the quad's which is stuck at 3Ghz, i tried 343 + 353 as multipier and neither seemed to work, unless i wasnt upping the voltage enough!
