Is my q9550 crap? should I return it and try my luck again?
I bought a new q9550 e0 a few days ago to replace a dead q6600

my new chip runs hotter at idle than my old chip did

I am running on a ep45-ud3p gigabyte motherboard

the issue is the max I can hit stable is 3.8GHz 450 x 8.5 @ 1.275v w/ LLC enabled...

thats pretty crap I am sure...

however I can up the volts and get it into windows @ 4.0GHz

the fpo/batch # is L933B616

I purchased this at a local store

I have a chance to exchange it for another at no extra charge... what should I do?

I am running on water cooling tdx block, 77 bonneville heater core fan shroud, twin 120mm fans in a pull thru setup, DD D4 pump

my old q6600 (g0) was lapped and polished, I ran it @ 3.2GHz @ 1.168v and it would idle around 18-20c (room temp around 15-16c normally), at full load it would max out around 45c

however at idle my q9550 runs @ 3.82GHz @ 1.248v but idles at (0) 32C / (1) 32C / (2) 41C / (3) 42C

now the weird thing is it only gets to around 52c on all cores at full load

I'd be quite happy if I could get my Q9550 to OC 1GHz and then run under full load at 52C.
Seems to me you had a Q6600 that was the exception to the rule rather than a bad Q9550.

I've had both and my Q6600 ran way hotter than the Q9550 with everything else the same.

At 3.6 GHz, my Q9550 (TRUE/S-Flex fan @ 1.3625 volts runs at 58 C - 61 C. It will boot at 3.8 but it's not stable.

At 3.6 GHz, my Q6600 (Xig Dark Knight @ 1.425 volts runs at 61 C - 66 C.

Your temperatures, if accurate, are great.

Same here.

I think the OP got lucky with the Q6600 and now performance expectations are a bit unrealistic.

I'm typing this on my Q9550 and after a lot of tinkering I got it to run completely stable at 3.5GHz but I have to give it 1.31V in order to do that.

Under full load I'm getting temps across the cores of 60C, 54C, 53C, and 53C.

Core 0 always seems to run a bit hotter than the others and it's been that way from day one.

By contrast you are running 300MHz faster and stable with less voltage and lower heat so you're doing great.

I'd almost be willing to bet that if you took that CPU back and got another one you'd more than likely not even manage to achieve what you have now.

52c at 3.82 and it doesn't OC very well?

Even water cooling going past 450mhz is a constant tinkering keeping the Q9550 stable and rock solid, but even if you do get to 4G stable pushing 470mhz, good luck keeping it there.

I've had mine stable at 4030mhz, ran P95 Small FFTs and Blend tests, it passes with flying colors, restart the machine the next day No Joy, the Q9550 C1 Stepping seems to like 3.82, but I'm running 1.38750Vcore to get it there, idling at 42c P95 at 62c.

I think you're doing pretty good, just know when to quit and be satisfied with a good OC, and IMO a 1G OC is pretty good, and there is nothing weird about your results.

omg, what cheap bastard you are, mate :D  i have the exact same q9550 - E0 stepping with a zalman cnps 9500 cooler and i get the same 3,83ghz upper limit if i want the system to be 100% stable... the difference is that i dont see the 4x1ghz FREE performance bonus as a failure, just ´cause its not a nice round clock at the end... btw, what do you need a 4 ghz quadcore for anyway? the only time i was able to produce full load on it was when ran the stress tests :D  oh, yeah AND when running GTA IV :D

You are new here, so if you want to be here a long time, put a clamp on your language, read the forum rules and comply with them, as this is the only warning you are going get from me. 4ryan6

I can actually run this cpu much much higher... I hit 4.25 stable for 24hours on linX... its the temps that worry me...

:)  I run my q9550 at 3.4ghz V1.25 with TRUE + Noctua NF-P12 Fan.
It gives me 52C in Prime95 at full load and 33C while typing this :)

Anything under 70 C is safe. Remember, P95 is loading all 4 cores to 100%. The odds of any other app/game doing that for sustained periods is pretty small.
