Q9450 OC / Temps / Settings

[nezzari]

Ah, I didn't see the previous posts. Yea, makes sense.

[Sem]

my Q9450 (L812B028) does 3.6 at 1.39v OCCT stable

will run prime overnight

temps seem funny

at full load coretemp shows 72,63,64,60 and realtemp shows 59,49,54,50

Just recieved my Q9450. Still waiting on my P5e3 Premium...
Batch nr: L806B255

Anyone has a Q9450 from the same batch as mine ?

Thats b/c core temp has the Tjmax wrong. Use realtemp.

How do you know about real temp but dont know why there is a difference in the programs???

where can I get q9450 oem ? sorry for offtopic

i know all about realtemp/Tjmax etc just posted both results anyway

what im talking about is the variation across the cores

my cpu isnt perfectly flat but its no worse than my E6600 and that had pretty even temps

the cooler is a thermalright ultra extreme

[jas420221]

oh my bad...!

when you say 'load' I assume you mean running small fft's in PRime 95 or OCCT correct? PLaying a game is not full load on the cores as most games out now most certainly do not balance our hte load on teh cores. Maybe thats why?

i had vcore - 1.4, vtt - 1.6, pll -1.6, nb -1.7, sb 1.6 --> WOW voltages!

i know right,kiss that setup goodbye so0n,lol.

1.4, vtt - 1.6, pll -1.6, nb -1.7

i cant belive 1.7nb and 1.4vtt everyone knows that killed a qx9650 in here.

Vcore doesn't really seem to play a part in these chips anyway. The FSB wall is hit long before the vcore gets dangerous.

Even the Q9550 doesn't look like it's getting past 4ghz too often, even under phase.

4ghz is quite easy with Q9550 (X3360) with any good cooling. I'm finding fsb wall is hit somewhere past 475fsb. Board is IP35-Pro (temp), cooling is xigmatek hdt-s1283 push/pull fans.

I just got my Q9450, Batch L811A851. Pack Date 5/02/08. VID 1.125 testing it right now. Also i think its a hard overclocker, but I'm going to do a burn in first. Its Idling hot at stock volts. 40C. Max temp on load is 62C right now.

[chance]

Great What's your CPU VID? I think in Q9450 is not so much important cause i've got one VID 1.250v and it's much better than my other with VID 1.050v.

I'm working on it right now. But the VID is 1.125 i think, But Its at 1.3325 in bios right now at 3.2Ghz, Currently in stress test using voltage 1.27. This thing is HOT at any voltage. I have no idea why. Core 1 is currently 70C, Core 2 is currently at 64C, Core 3/4 is at 67C. My Q6600 wasn't never this hot. Also the Chip idles hot too for some reason, its about 65F in my room right now. I don't get it. it should be running alot cooler then this.

Just picked up one from a local Microcenter. It's L812A528 with 5/5/08 pack date.
One odd thing though, there was also another one with 5/5/08 pack date, but older batch of L811A9xx
By the way, MC is still selling a Q9450 for $299

[Warboy]

I got C1 stepping, I think there is a problem with C1 and my motherboard, I can't go above 430 so far. I gotta keep trying. The C1 stepping started to get worked on Bios in the 1004 bios for Maximus Extreme. I'm trying 1007, and 1101 right now. No luck. The CPU is still running hot. But Max Load temp has gone down about 2-4C.

[jas420221]

Warboy you running coretemp or real temp fo rthat quad? Core tmep is 10C hot...

I've tried Real Temp first, then Core Temp, then Everest. Most of my readings are from Real Temp. v2.5

Have you considered lapping your CPU/CPU cooler heatsink?

I just did the other day, and core temps have fallen between 5-10 degrees C.

Testing stability @ 3.6GHz right now

[Cob]

I haven't the balls to lap mine yet. I'm gonna wait to see if the Wolfdale degradation is really true or just a myth.

I'm dying to do it as currently under folding load my core temps range from 46c to 54c.

[jas420221]

There is nothing wrong with those temps COB... though I agree any little bit can help!

[Cob]

Yip the average temp is fine, but the 8c difference between the coolest and warmest core is annoying.

[GreyMouser]

I just got finished running some tests with my new Q9450 from MC yesterday. Packed 5/5/08, and it's running hot too, with a 10 degree difference between the hottest and coolest cores. Don't remember the batch number right now, but the VID was 1.125. Maybe this latest batch is somewhat of a bad run?

Did you guys run that test on Real Temp? To see if you have sticking sensors? (grasping at straws here). The differences in mine are at most 3Cm normally 1-2C (pre calibration of course).

[Cob]

Yip I did, and the sensors were fine

[Nits]

I think the stuck sensor thing only happens @ load - not when idle, so it should be easy to tell. Mine are also stuck on idle. After lapping difference between cores @ load is around 4-5 degrees.
