Q6600 OC

[ImperfectLink]

EVGA 680i SLI with OCZ reaper pc6400 running at 915mhz (3:2)

 

[DJBoo]

I just built a new system and went with the Q6600 on sale at microcenter for 199, $214 with tax. See my sig for system. I tried to go 3.6 ghz but at max utilization I was close to 70c say 68c Tcase 70c Tjunction , so I backed down to 3.2ghz, running good

I am getting idle 38 to 40 c and load 58 to 60c (Tcase temps) , thats max load with 4 prime95's going on cpu.


I have read max TCASE for Q6600 GO is 71C and MAX TJUNCTION is 100C per core , correct me if im wrong.

yeah mine was getting hot at higher clock too. my case has terrible air throughput though so i think its attributed to that. after the pencil mod my vdroop virtually went away. vdrop is only 0.02V as well.

What heatsink are you using DJ?

 

[ImperfectLink]

ah woops. helps to read sigs. I'm using a tuniq tower.

bump to see if others agree or not with Q6600 GO max temps.

This link is awesome for finding Intel specs - http://processorfinder.intel.c...m=2774&sSpec=&OrdCode=

For G0 specifically - http://processorfinder.intel.c...tails.aspx?sSpec=SLACR

Thermal Specification: 71°C

Thermal Specification: The thermal specification shown is the maximum case temperature at the maximum Thermal Design Power (TDP) value for that processor. It is measured at the geometric center on the topside of the processor integrated heat spreader. For processors without integrated heat spreaders such as mobile processors, the thermal specification is referred to as the junction temperature (Tj). The maximum junction temperature is defined by an activation of the processor Intel® Thermal Monitor. The Intel Thermal Monitor?s automatic mode is used to indicate that the maximum TJ has been reached.

it's in my sig. I think the temp is a lil high still. Have anyone opted TT120 TX1 for something else? Like AS5?

I like AS5 ot TX-2 for my Tuniqs. TX-1 and Ceramique were both balls hard to get to form a thin layer for low temps. TX-1 is like silly-putty if anyone remembers that stuff from the 80's.

Your temps are no-doubt rather high give the 1.6V you are putting on that sucker. Is that really correct and not a typo? Shizer. My G0's run 3.3GHz all at <1.33V (small FFT stable). Why so much Vcore on yours?

 

[GarfieldtheCat]

Q6600 G0 running at 3.5GHz @ 1.392V, RAM running 1:1

Max temps with small FFT's are ~61C on all cores, and is 12 hours prime stable. Running a TRUE with an undervolted 120mm fan

lol i meant 1.16v:laugh:

I'll update it now.

Then yeah I'd say your temps seem a tad high for that voltage (1.16V) and clock (3.2GHz). I'd blame the TX1 before anything else. Replace it with some AS5 and your temps will likely drop 5-7C.

Yes, I have to say, something is awry. 1.16 vcore and 60c temps on a G0 are just out of line.Either your case airflow is bad, or your mounting is not quite on, or your thermal paste is too heavy or something.....

I get 44-48c @ 1.35 vcore @ 3420 on the G0 Q6600 machine I am typing on. It was up to 54c when it was not in the Antec 900 case. But at that vcore and speed, you should be where I am or better...Unless you live in the Sahara.....

I really cant find out what to clock my Q6600 at, atm I am running 9x356 = 3200 but with a 1.41Vcore, but this gives me a 70-85 core temp readings. And I cant see how this can be real its supposed to be that hot :/


Setup
Q6600 G0
Abit IP35Pro
Scythe Infinity

woah.... i just remember to tell you guys that each chip carryes a YMMV (your milage may vary) tag.

So unless you can get down to the same bin, meaning if mine was L722B123 you would need to find another L722B### to get any real comparison with it.

And even then, theres always golden eggs and black sheeps amung the batch.

So use values as ball parks. Maybe even stadium parks. And people have different cooling @ different ambients which will offset temp comparisons by a lot.

i'm testing my Q6600 1.2125VID with OCCT right now


8 x 425 = 3.4ghz 1.325vCore
1:1 Ballistix 850mhz 2.2vRam
Ds3p Rev2.0 F10 bios

 

[Schmide]

I just got my system up and running with vista 64 watercooled with a TDX. Haven't started overclocking yet.

Running Prime for an hour on at 2.4ghz and getting (coretemp)

c0 38-40c
c1 39-42c
c2 34-37c
c3 37-39c

(the 800000 LLI are much hotter than the 4000 LLI)
If i wake up with numbers like this, this is going to be a great oc chiper.

 

[taihuia13]

Mine 1.38 in bios at 23 degrees ambient hottest cores get on prime small fft is 63.

 

[LOUISSSSS]

i was 2 hour OCCT CPU stable with:

Q6600 g0 1.2125VID
1.3375 vcore
8 x 440
Ballistix DDR2 800 440mhz 4-4-4-12

 

[Drsignguy]

Got my Q6600 G0 @ 9x345=3.1 with a voltage of 1.400 (idol). CPU-z reports 1.392, with 4x2048 geil. OCCT stable.

 

[Syzygies]

I found it helpful to make a spreadsheet grid, volts by Ghz, to track which combinations did or didn't work. One tends to see a line of feasible combinations, before one gets into crazy territory and voltages bend sharply upward. And 3.2 to 3.5 Ghz is not crazy territory.

For my G0 Q6600, the following pairs work:

3.2 Ghz, 1.28750 V (62 C max at full load)
3.3 Ghz, 1.31875 V (+0.03125)
3.4 Ghz, 1.35625 V (+0.03750)
3.5 Ghz, 1.40000 V (+0.04375)

So my numbers curve up a bit from a straight line, but I'm not yet at the brink.

One little-understood source of instability is "refresh to ACT", for which there's an advisory over at the OCZ support forum, and a mention in Kris Boughton's latest mobo review on AnandTech. I came back from a trip to find formerly stable overclocks now unstable, and started raising Vcore as a knee-jerk response, until it became clear that wasn't it. I then found a better 3.2 Ghz overclock 9x at 356 FSB, 1068 5-5-5-18 DRAM than the 8x, 400 FSB, 800 4-4-4-15 DRAM that was now failing me, and decided to live with it. But it was nagging at me that my mobo couldn't handle 400 FSB at tight memory timings.

Relaxing "refresh to ACT" to 54 bought me absolute stability. Nothing was wrong with my mobo or memory, just one more thing to learn, instead. Hey, it was getting boring until this issue, but I can see why people buy Dell.
