Post your E4300 Overclock!

[CompuTronix]

Let's double check. Please fill in the blanks:

when expressing Idle & Load test results, it's also necessary to define the variables such as:

Tcase = Idle & Load
Tjunction = Idle & Load

Ambient = Room Temp
Chipset = Model
C2D = Model
CPU Cooler = Model
Frequency = CPU Clock
Load = Test Programs
Motherboard = Model
Vcore = CPU Voltage

Thanks,

[Viceras]

Tcase = 16-19C & 35-41C

Ambient = 19C (Yes its cold here in Sweden :twisted: )
Chipset = 965P
C2D = E4300
CPU Cooler = Arctic freezer 7 pro
Frequency = 2997MHz
Load = Orthos - Prime (vista OS)
Motherboard = GA 965P DS3 Rev2
Vcore = 1.350

Ok I think thats it 😉

EDIT; Not sure if it matters but NB@+1 FSB@+1 DDR2@+2 vCore 1.350

 

[CompuTronix]

Tjunction Idle & Load?

 

[Viceras]

Tjunction? would that be system temp if so its 30C Idle/load (Fans right on it 😉)

Interpretation

* The first part of the spec refers to a single measuring point on the integrated heat spreader, which would be in contact with the CPU cooler. Since there is no laboratory test sensor at this location, the CPU Case Thermal Diode is used to display the CPU temp in BIOS, where thermal tables are stored to emulate the heat spreader. This represents an average value between dual cores operating at unique temps. Intel's Thermal Case Maximum spec (Tc max) of 60c is the hot limit, 55c is warm, and 50c is safe. The single CPU Thermal Case sensor is how Tcase temp is measured. Tcase is the CPU temp displayed in BIOS, Motherboard Utilities, and SpeedFan 4.32.

** The second part of the spec refers to mobile processors without an integrated heat spreader, measured by internal Digital Thermal Sensors. Since Intel's Thermal Analysis Tool (TAT) is a Notebook tool, and desktop C2D's have an integrated heat spreader, the software tool "Core Temp" compensates ~ 2c higher, and shows Intel's Thermal Junction Maximum spec (Tj max) of 85c as the shutdown limit. 80c is overtemp, where TAT redlines and the CPU throttles, 75c is hot, 70c is warm, and 65c is safe. The dual Thermal Junction sensors are how Tjunction temps are measured. Tjunction is the dual core temps displayed by TAT, by Core Temp and SpeedFan 4.32.

Thermal Flow

Heat originates within the cores, and is highest where the dual Tjunction sensors are located. Heat is then dissipated throughout the CPU die to the socket and motherboard, and to the Integrated Heat Spreader, where the single Tcase sensor, located between the cores, is 15c lower. Heat is then transferred to the CPU cooler, and finally to air inside the computer case. CPU temperatures are then determined by computer case cooling efficiency and Ambient temperature. Regardless of Load, Tjunction is always ~ 15c higher than Tcase, and Tcase is always higher than Ambient.

Findings

The temperature differences between Tcase (BIOS, Motherboard Utilities and SpeedFan 4.32), compared with Tjunction (TAT, Core Temp and SpeedFan 4.32) is Tcase + 15c = Tjunction. TAT can be used simultaneously with Core Temp for thermal benchmarking desktop C2D's at 100% continuous load. 50c Tcase and 65c Tjunction are sustainable full load temperatures.

[Viceras]

Tjunction temps from Speedfan = 25-28C Idle / 36-39 Load (Orthos 90%FL + Browesing, Music & Full sys scan on System Mechanic :twisted: )

Appreciate all the help / advice I can get; Thanks for your time 😉

The Comp is actually still very responsive 8O

Maybe i'm reading it wrong this is what Speedfan says; Temp1 - 30C Temp2 41C Temp3 -2C Core 0 41C Core 1 41C if that makes any sence at all to anyone 😉

 

[TyroneShoelaces]

I'm not looking to break any speed records... just wanted a nice, stable overclock...

Gigabyte DS3
2GB Corsair DDR2 800
E4300
7800 GT

9x320 = 2,880 MHz
RAM Multi = 2.5

The part I find amazing is that I didn't have to increase any voltages, and IN FACT, I am UNDERvolting the CPU. Currently have it at 1.3125. I will do some testing to see how low I can go and stay stable. Ran Orthos just fine overnight.

My only concern is temps, while undervolting and using a Scythe Ninja in an Antec 900 case, the temps get up to around 70C using TAT. I think I'll try reseating the Ninja, or trying some Arctic Silver. Right now I'm using the Geil Copper.

Can anybody with experience using both Geil Copper and Arctic Silver testify to how much better A.S. is, before I go buy a tube?

Thanks,
TyShoe

 

[Viceras]

TAT adds +15C to the E4300 This may just be a vista bug but from my experience all other temp software has been 20 - 15C lower than TATs readings with this chip/OS

 

[CompuTronix]

I'm still working on your temp response, but you should know that the Guide was updated 3/5/07, and redefines TAT's relationship, as well as other programs, with respect to erroneous temps, so your comment has been superseded. I recommend a re-read of the Guide, with emphasis on the Troubleshooting section.

[TyroneShoelaces]

I'll definitely reread the temp guide. If what you say about TAT and the E4300 is true, it makes sense... I hit around 58 with Orthos. So, I actually have a little more room to try higher, then?

Think the Arctic Silver would help, too?

-TyShoe

 

[Viceras]

Ok will do Thanks for your effort; Update to my temps they hold true during the TAT + Orthos 10minute torture test (The PC was responsive throughout 'Not very but still :twisted:') At its height TAT read 15C above Speedfan for a Max of 56C on each die all other temp monitors read 42-43C So its obvious TAT is giving a false reading or atleast i hope it is 😉

Ok off to read the revisions

 

[CompuTronix]

I can't analyze your temps without complete information. Please fill in the blanks:

when expressing Idle & Load test results, it's also necessary to define the variables such as:

Tcase = Idle & Load
Tjunction = Idle & Load

Ambient = Room Temp
Chipset = Model
C2D = Model
CPU Cooler = Model
Frequency = CPU Clock
Load = Test Programs
Motherboard = Model
Vcore = CPU Voltage

Stock Voltage no mods there, just a good aftermarket heatsink and fan ..

E6300 @3.1Ghz



@40C


Very Stable ... Next is 3.7 then I'll return the chip for a new one lol j.k

 

[CompuTronix]

Viceras, so the information you gave me for Tjunction Orthos and Prim95 Load was incomplete?

 

[Viceras]

Sorted even if TAT is true which I highly doubt i'm still within normal tempratures according to your guide; Excellent, i'm delighted with my first OC my only worry is how addictive its becoming :twisted:

Final Fully Tested setup;

E4300 @ 2997MHz (333x9) 16-19C Idle / 35-43C Full Load (TAT100% + Orthos 88%) DDR 800 Underclocked to DDR 667 (tightened timings to 4 4 4 12) Voltages; DDR +2 (2.0v) FSB +1 (1.30v) (G)MCH +1 (1.55v) vCore 1.350v

Now to build another; :twisted:

 

[Viceras]

No, the info is complete I was just double checking 😉

 

[CompuTronix]

Stanby...

 

[MEGAWATTZ2000]

How can some people get away with not touching voltage or memory settings while others have to try different steps etc? :?

 

[Viceras]

Because not all parts are identical some are better than others, besides all S3 and DS3 models need the NB nudged up one from what i've read.

 

[CompuTronix]

What is TAT idle?

 

[Viceras]

TAT Idle 35-40C

 

[CompuTronix]

Thank you...that presents a completely different picture...standby...your answers are coming...

Comp 8)

 

[CompuTronix]

Tcase = 16-19C Idle / 35-41C Load
Tjunction = 40C Idle / 56C Load

Ambient = 19C
Chipset = 965P
C2D = E4300
CPU Cooler = Arctic freezer 7 pro
Frequency = 3.0 Ghz
Load = TAT 100%
Motherboard = GA 965P DS3 Rev2
Vcore = 1.350

See the problems?

Thermal Flow

...Regardless of Load, Tjunction is always ~ 15c higher than Tcase, and Tcase is always higher than Ambient.

No temps can be less than ambient, and Tjunction is always 15c above Tcase. Although TAT meets these Parameters, Core Temp, SpeedFan and Everest do not.

Scale

The temp scale shown in the example below illustrates the normal ~ 25c range between Idle and TAT @ 100% Load, and the typical ~ 15c difference between Tcase and Tjunction. 50c Tcase and 65c Tjunction with TAT @ 100% load are safe and reasonable temperatures.

Tcase/Tjunction

--70--/--85--85-- Shutdown
--65--/--80--80-- Throttle
--60--/--75--75-- Hot
--55--/--70--70-- Warm
--50--/--65--65-- N
--45--/--60--60-- O
--40--/--55--55-- R
--35--/--50--50-- M
--30--/--45--45-- A
--25--/--40--40-- L

Results

Tcase (BIOS, Motherboard Utilities, SpeedFan 4.32) = 30c Idle, 50c Load
Tjunction (Core Temp, SpeedFan 4.32 highest core) = 45c Idle, 65c Load

The above temp Results are normal. If you run TAT and Orthos simultaneously, TAT provides 100% Load, while Orthos does nothing, so don't run them together.

Variables

Even false temperatures have offsets which can be analyzed, and when given correction factors, may still be reasonably accurate.

Parameters

(B) Tjunction is always ~ 15c higher than Tcase.

(C) Tcase is always higher than Ambient.

(D) Tcase Idle should be ~ 2 to 15c higher than Ambient.

(E) Tjunction Idle should be ~ 15 to 30c higher than Ambient.

As you can see, except for TAT, your temps don't meet the Parameters.

Troubleshooting

(A) Vcore will typically sag ~ .025 volts under Load.

(B) Offsets between Core #0 and Core #1 of ~ 3c are normal.

(C) SpeedFan 4.32 can be configured to correct for Tcase and Tjunction offsets.

(D) Any hardware and / or software may misreport Tcase and / or Tjunction temps.

(E) 965 chipsets may misreport Tcase and Tjunction temperatures with +/-15c offsets.

(G) TAT may not run on Vista. Orthos Priority 9 Small FFT’s simulates 88% load ~ 5c lower.

The problem is that your Tcase temps are offset by -5c, and your Tjunction temps are offset by -20c. TAT is close, but in your circumstance, is still low by 5c. I recommend that you follow the Offsets section of the Guide to configure your Tcase CPU temp for +5c, and Tjunction Core 1 and Core 2 temps for +20c.

Offsets

If temperatures don’t meet the Parameters, then SpeedFan 4.32 can be configured to correct for Tcase and Tjunction offsets. From the “Readings” tab, click on the “Configure” button, then click on the “Advanced” tab. Next, click on the “Chip” field directly under the tabs, then use SpeedFan’s “Help and HOW-TO” icon included in the installation Program Group. Under “Contents” click on “How to configure” then click on “How to set Advanced Options”. Read this entire section including “Other interesting options” and “Temperature x offset. When configured, SpeedFan will provide a means to display all 3 Tcase and Tjunction temperatures correctly. SpeedFan is also extremely useful for observing temperatures and voltages using the “Charts” tab, while thermal benchmarking with TAT.

Corrected Results:

Tcase = 21-24C Idle / 40-46C Load
Tjunction = 45C Idle / 61C Load
Ambient = 19c

Hope this helps,

Comp 8)

 

[TyroneShoelaces]

Tcase = 19-20C Idle / 54-55C Load
Tjunction = 34-36C Idle / 68-70C Load

Ambient = 18C
Chipset = 965P
C2D = E4300
CPU Cooler = Scythe Ninja Plus Rev B
Frequency = 9 X 320 = 2.88GHz
Load = TAT 100%
Motherboard = GA 965P DS3 Rev2
Vcore = 1.3125


How does this look? One thing that jumps out at me is this...

(H) Idle to Load Delta should not exceed ~ 25c.

I'm getting a Delta of 35C.

Thanks,
TyShoe

 

[Viceras]

Hmm, Not sure I understood that, the case is colder than the room and the room temp is 19C in everest the GPU Ambient is 29C would this be considered Ambient temprature?

Looks like theres much more i have to learn :?

EDIT; Just seen your edit so does this mean my temps are normal? high? should I go down a step or two? I'm going to start lowering the voltage see how low I can go.

Thanks!
