Q9450 OC / Temps / Settings

[Gen]

i don't have a 45nm quad but intel states max VID is 1.3625v. i would not go over 1.4v load, 1.4v vtt or 1.4 pll on any 45nm chip.

Ok, Im under the voltage on idle and load. VTT is 1.4 from 1.3 stock (not sure if I can lower that or not, I will have to check stability). And I dont believe my bios/mobo has a 'pll' option (or its not named pll).

So 1.4 is the highest 24/7 voltage (to get 2 years out of this chip possibly).

500. But I can't go beyond 30 minutes because the onboard VGA keeps dying and crashing the computer. I need the 9800GTX here....

Just disable it

[ACE76]

so would you consider it better then the ultra 120 extreme? cause im shoppin for a new HSF cause im questioning my zalman 9700 nt at the moment.

Wow, I'm in the same shoes as you...I'm not trusting my Zalman 9700NT anymore either and i'm actually surprised it isn't cooling better considering it's very shiny and straight bottom...I ordered the Xigmatek Red Scorpion cooler which is an updated version of the much hyped S1203 cooler...only thing I didn't like was the fan's cfm rating so I ordered a 110cfm fan to use instead of the stock one

I'm trying to cool a QX9650 so I hope it does better than the Zalman.

110cfm sounds loud, which one? imo i would go with a true and use low noise fan(s) like a yate for the same performance (as long as price wasn't a concern).

I don't have anything else to connect the monitor to at the moment. :p

Pish, seen higher output fans then that:

yes, so have i, i was mainly stating how loud those fans are. i have a silverstone fm-12x that i don't use and it is so loud @12v that i can't use the phone in the same room

Anyone... what is the general consensus on the highest 24/7 volts on high end air????

On water it's a 24/7 system @ 3.8GHz now for me after hours and hours... of stress testing /zzzZzz

High end air is not far from my water system.
It depends a lot on the cooling on the N/B too.
But 3.8Ghz too I guess.

Anyway, besides world records or such I don't see the point to go to 4GHz+ when we are already lucky to have a 100% stable 3.8GHz while staying in safe voltage ranges.
I burned too many boards and too many RAMs. I don't want this to be the first processor I burn

[RunawayPrisoner]

Aww! Don't be... safe! Intel doesn't like it when you are!

But seriously, I think on either extreme air or water, 3.80GHz should be the limit. Unless you think you are adventurous enough to stand 4.00GHz (1.48v vCore!). 3.80GHz at 1.38v is really a lot to me already. And the X3350 chip only required 1.304v for 3.80GHz, too...

I agree. I mean the zalman 9700 nt is a beautiful cpu Hsf and the build quality i second to none but its really only good for stock to mild OC systems and for the price i paid it should be able to hang with the big boys.

Got my stuff in a week ago, been running it at stock and decreased CPU voltage to 1.05 from 1.2. Have spent the last few hours trying to stabilize my overclock now. So far 3.6 stable at 1.375 and +1NB for 2 hours. Time to try 3.8. Only thing that kils me is the difference between the motherboard reported temp of 43C and realtemps 57C. Not sure which to believe as it is such a big difference. Realtemp reports my idle at stock as 42C and im on water.

[RunawayPrisoner]

Ouch... I just found out that this is all I need for 475:

vCore: whatever works.
vPLL: 1.50v in BIOS
vFSB: 1.20v in BIOS
vNB: 1.43v in BIOS (1.45v real)

So... almost all stock! vCore is a bit high, though. (But everything else is shockingly lower than what X3350 required!)

Well 3.8 was a no go. I am unwilling to up my voltages any more than I did for 3.6 so I guess I'm stuck here. Not too bad tho, now I'm just gonna work down the voltages a bit for my 24/7. Running 30 minutes at 1.35V or reported 1.31V in EasyTune.

Sounds exactly like what I have on my Abit IP35-Pro board ...

[Richard Dower]

What voltage are you guys finding is nesscary for 3.6GHz?

[JustComputers]

Rich, i have my voltage set to 1.356 in bios, it is showing as 1.3v in EasyTune and cpu-z(1.442) is reporting it at 1.28 which is probably bugged. This is prime stable for 4 hours. My temps are 41C reported by EasyTune and 56C reported by RealTemp. Not sure which to believe as RealTemp seems to report my stock temps @ idle somewhere near 45C.

[YorkiS]

I have it in 1.280v and runs very well

24/7 @ 3.6GHz

Real Temp reports correct temperatures for me, so... that might be a sign for you to back your volts down a bit.

[sbinh]

Look likes CORE#1 is not running ... Temps on other 3 cores are ~45*C while core#1 = 27*C ...

[JustComputers]

Might be working fine Runaway. But I am getting really bad temps at stock voltage and stock speeds. 40C idle, on watercooling. Then with increased voltage and overclock under full load it only jumps to the mid to high 50's seems like too little a jump to be reporting correctly. As far as Easytunes reading, i would never trust them as I believe they report the socket temp. On a positive note at 3.6 I ran a 13.588 1M SuperPi and a 19106 in 3dMark06 (750/1100 9800gx2)

[sbinh]

These are what I got ... from 2 different boards:


Asus P5K-Dlx, OCZ DDR2-1066
vcore: 1.25v (BIOS)
vdimm: 2.10v(BIOS)
Temp idle: ~33*C (RealTemp)
Temp full loaded: ~48*C (RealTemp)




Abit IP35-Pro, OCZ DDR2-1066
vcore: 1.35v (BIOS)
vdimm: 2.10v(BIOS)
Temp Idle: ~42*C (RealTemp)
Temp full loaded: ~58*C (RealTemp)

[RunawayPrisoner]

Nice chip, SBinh. I guess some are just nicer than others. In fact, I bet I can get 4GHz stable with yours at 1.42v vCore... whereas with this chip I have right now, 1.50v is required for 4GHz stable...
It could just be because the motherboard is trying to compensate for the PSU, though. I shall see to that later on.

3.6GHz on the Rampage board is really easy.
I just set strap to 333, FSB frequency to 450, the right voltage for my RAM and all the rest on Auto.
It's OCCT stable and I can see the CPU voltage fluctuate around 1.27V under load.
(I checked the other voltages selected by Asus with Everest and it's safe/ok).

Usually "Auto" settings was a NO for me when overclocking but it seems Asus improved a lot for that.

For 3.8GHz, it's close to boot in Windows just with FSB frequency set to 475 and all the rest on Auto.
The only setting to change to make it fully boot to Windows for me was to set N/B core voltage to 1.73V.
Then you need to tweak the settings to make it OCCT stable.

1.73v for NB? Seriously?
