Intel Core 2 Quad Q9450 overclock Temp fears!!

nathancarter · Apr 3, 2014

Hello all,

I have read numerous posts about overclocking the Q9450 but i hope to erase any fears i have with you fine people.

I have a q9450 at 2.6GHZ

I have 8gb running at 800mhz (should be 1066) but was down-clocked as cpu couldn't handle it.

Also a Nvidia gtx 660 2gb

My temps sit at on Core temp and Realtemp

core 0 = 44
core 1 = 44
core 2 = 34
core 3 = 34

running prime 95 at full load my core look like this.

core 0 = 61-62
core 1 = 61-62
core 2 = 55-56
core 3 = 55-56

I have got a new heat sink an Alaska and my room temp is good, i have re-applied heat sink paste several time to get it perfect.

I am too frightened to overclock at the moment with these temps.. what else can i do?

I am so lost... is my ram suffering much from running at 800mhz as apposed to 1066?

That cpu is rated for a max of 71degrees.

Underclocked RAM don't cry.

Hello sunder25,

So with these temps i shouldn't overclock? and the under clocked ram is no bother (computer is solely used for gaming)?

sunder25 · Apr 3, 2014

I'd not bother about underclocked ram.
You can afford to OC your cores some for normal usage, nothing you do will heat them up as much as prime95.

Hello Sunder,

Thank you for the prompt response, i will now overclock my cpu to 3.0GHZ and my ram to 900MHZ i will reply with idle temps and also thanks for the info about prime95 i had a hunch nothing would use 100% of each core.

sunder25 · Apr 3, 2014

Woah not so fast.
The secret to a nice overclock is small increments.
Try 2.75-2.80

sunder25 · Apr 3, 2014

I'll wait for your results.

nathancarter · Apr 3, 2014

Hello,

Overclocked cpu to 3.0GHZ and ram is now upto 900MHZ

Idle temps are now

core 0 = 55
core 1 = 55
core 2 = 46
core 3 = 46

Im a little nervous to run prime95 is this idle temp ok? should i try to go further? or be happy with that.

nathancarter · Apr 3, 2014

oh.. opps i ran off and started playing around sorry

sunder25 · Apr 3, 2014

Idle temps are quite high,
I'd take it down a peg, or check temps under normal loads.
Play a game.

nathancarter · Apr 3, 2014

just downloading a game to test.

Idle temp is.. still rising...

core 0 = 59
core 1 = 59
core 2 = 51
core 3 = 51

sunder25 · Apr 3, 2014

Time to go to 2.8

nathancarter · Apr 3, 2014

well... what a mess around..

down clocked down to 2.8GHZ and temps jumped to 130c on all cores and computer wouldn't turn on until i removed cmos battery and put cpu back to 2.6GHZ.. temps are back at 44-34c

wtf...

sunder25 · Apr 3, 2014

Jumped to 130c?
That makes no sense lol.
Are you sure you didn't add a 0 here or there?

nathancarter · Apr 3, 2014

yeah i agree, i shut down went into bios changed multiplier from 375 x 8 to 350 x 8 and rebooted go to desktop and checked core temp and all cores were sitting at 130c! flashing at me!

I am confused!

nathancarter · Apr 3, 2014

i recall this happening to this same cpu years ago when i went to 350 x 8 it got crazy hot.. so odd..

nathancarter · Apr 3, 2014

thank you mate i will go read it now

Good luck!
