Reseating heatsink and reapplying the thermal paste may help. I had a similar situation with a Q6600 back in the days and turned out there was a bubble amid the MX-2. No, you can't find it by simply checking core temps; you have to open it up and check physically. Due to the MX-2's watery nature I changed back to my good'ol thicky Ceramique. Since then I no longer suffered the clock degradation again.

ned help whit GLT to the cpu
Late to the game here
Just pick'd up a Q9650 FPO L828A446
4.2GHz was a walk in the park, but my concern is the temps.
3 cores are nice and cool 29c-31c but the 1 core is a staggering 40c, this is water cooled and yes I have checked the mount and reseated twice.
Anyone else have this issue or am I the lucky winner today?
I'm in no hurry to lap the the chip for I might sell it if I cant do 500x9
I have the same thing on my 9650. One of my sensors is always a LOT higher than the rest. I attribute it to sensor error. I have a hard time believing that one core on the same die could be 10c higher than the rest. I just ignore it.Quote:

But; if i never even looked at my temps and I relied on the cpu-overtemp-protection I bet I could use this chip for years, and NEVER have a problem.
Just my 2-cents.
ASUS P5Q Deluxe Bios 1805 Q9650 L844B809 VID: 1.250
volt set to the fsb
watercooling
4.4GHZ 1.36v
4.5GHZ 1.52v xtream high or :confused:
4.6GHZ 1.56v
Thanks for the reply,Quote:

No tweaks, first run

As a matter of fact. my core 1 is also the high one. Other 3 are 'normal'.
Folks, don't bother with any core temp readings below 50°C - they are simply not accurate. Quote from this recently released Intel datasheet regarding the thermal sensor issue:
From my own tests, I found it better be corrected to "60°C" to be closer to reality. Anything below 60°C in my experience doesn't make much sense at all.Quote:
The digital thermal sensor (DTS) accuracy is in the order of -5°C +10°C around 90°C ; it deteriorates to ±10°C at 50°C. The DTS temperature reading saturates at some temperature below 50°C. Any DTS reading below 50°C should be considered to indicate only a temperature below 50°C and not a specific temperature. External thermal sensor with “BJT” model is required to read thermal diode temperature.
Also here's an article at Tom's HW that's worth reading. It talks about how to set the Tj Max value accurately for your CPU.
Im pretty sure posting a link to toms is against the forum rules or at least it should be.Quote:

I have found that to be true.
After testing yesterday, the temps seem to even out above 50c or so, core1 is still 10c higher on load but it now dosent bother me so much.
Thanks for the info
Hey Grn i have the same batch :up:, my mate Jor3lBR get it for me and also the UD3P great combo !!! still on my way to my country, such a low vid it's hotter than my other 1,25vid, but in the end he told me that the domino was not doing good contact so will see how it goes on my D-TEK block, also some sensors where stuck at first start all stock but after some burn in days they start movingQuote:

I wanna thank all members of this thread and others for all the great help always and specially to my friend Jor3lBR for his hard work and patience, thanks
for your pics, screens and all the time you spent on finding a good one and testing it day after day :clap::clap:
You rock mate :up::up:

Gold chip, bro :up: Congrats
Thank you mate :up: I'm anxious waiting the combo :DQuote:

Yes you have a sweet chip there for sure, and you have motivated me , I just managed to reduce vcore for 4200, still tweaking but its looking good

I told you there is no better combo then the UD3P+Q9650 :up:
Your system was great to tweak, took me those 3 days as you know we talked most of them during the OC's in MSN.
Hopefully it will arrive safe next week so you feel the power of 4500MhzQuad!
:rofl: That was my intention :D, so far i sold the MF2 it was holding me back like crazy this UD3P are awesome mobos :up:Quote:

Thanks my friend of course i'm happy if have no more fingers to cross :rofl::rofl: my hands and feet are crossed to pass customs this next daysQuote:

Core Temp reports VID as 1.15 so does Real Temp.Quote:

Messing with clock skew now to settle this chip down.
Yes this UD3P's are much better for sure...you'll get some rock solid clocks there...Quote:

Batch# L844B801 SLB8W Pack date 01/29/2009
VID 1.25 (no stuck sensors)
4.05mhz Linked and synced with 8GB's of DDR3. This was very difficult to achieve with my S2E, she's a real beeatch with 8GB's of RAM. Have posted and booted in Vista as high as 4.14mhz linked and synced but not prime95 blend stable. Working on lowest possible cpu volts with LLC disabled now. looks like she needs at least 1.42 underload to hold 4.05mhz.

On the S2E's it over volts to hell, it has also been linked to instability with BSOD's at idle and what not. I have not had any issues but I wanted to have stable settings both ways.Quote:

I think I have a crazy board.
Nice work there man... GReat chip and nice of Jor3 to help you out and mail it there.
I'm now wanting a better board after seing you people's results. but I've yet to try and OC my chip with my new Water loop. I'll be doing that tonight, or tomorrow.
