Even without any modifying of the settings, TAT is saying I am running 50 degree temp.
On an interesting note, BIOS says I am running at about 29 degrees without overclock, 40 degrees with an overclock.
I also remember that someone said TAT was not working for E4300s?
Oh, for cooling I have an Antec 900 case with a case fan right over the processor, and then the stock fan with some cheapo Silver Thermal Compound from Dynex, which is a generic brand. ANd I agree, with such a mild overclock, hell would I even need thermal compound?
TAT works on Intel chipsets. You're comparing 2 different C2D temperatures, like apples to oranges, so please read the Core 2 Duo Temperature Guide again, then test and post your variables and results as shown in the Guide.
A simple breakdown (as I understood the guide). The BIOS reads an external temp sensor, which since it's further from the heat source (the CPU cores) it'll read lower than TAT (which reads temp sensors INSIDE the CPU cores).
Ok, followed Core 2 Duo Temp Guide but still have some questions. I ran everything as planned and here are my results:
I am now running 240 megahertz with a 9x multiplier, for 2.16 gigahertz. I am letting BIOS run on auto for voltage management.
Without any load:
TAT says 54 degrees on both cores
Speedfan says both cores are 39 degrees and temp 1 and two are both inbetween 30 and 33.
CPUZ says the BIOS automated settings are running the vcore at 1.424. The sped is 2.16 with 240x9.
On full load:
TAT (with both processors clicked to 100% full load): I let it only go to 87 degrees on the first core, 85 on the second before I stopped full load testing. This means I have a 30 degree variance, which the C2D guide says is unacceptable.
Speedfan says the temps for Core 2 and Core 1 are 68 degrees and 70 degrees, respectively (this is the information at the bottom of the list on the right side where readings are listed).
CPUZ shows the Vcore to 1.394.
After reading the C2D guide I am not sure if I understand it, but are these temps highly abnormal for a E4300? I tink that when reading the core 2 duo guide it said that TAT should not go above 85 degrees, but there is was, reading an 87 degree temperature.
Of note: I am running a P965 chipset, which the guide says is trouble. Could it be the chipset?
Here are my specs:
E4300 overclocked to 2.16 gigahertz with stock cooling and Dynex thermal compound.
650watt Xclio powersupply
Antec 900 case, with another fan located above the processor.
Ambient temps say 29 degrees celsius.
Ambient= 29 degrees celsius
CPU Cooler= stock (I have no idea what the model is, but something tells me its the one that comes with all C2Ds)
Frequency= 240 megahertz
Motherboard= Gigabyte S-3
Vcore= it is varying I guess because I left voltage optimization on auto, but 1.424 with no load and 1.392 under load.
Would this place so much load on the CPU to achieve these crazy temps? Should I disable it?
Also, I've been getting past 85 degree temps on TAT under full load, and Core Temp says more like 89 (!). I will re-align the heatsink tommorow.
If Core 1 and Core 2 inside Speedfan is Tcase heat, than shouldn't it be the same as 15 degrees below TAT's rating for internal heat?
My thoughts are that TAT is off, I do remember reading some place that the E4300 was not read properly by TAT and henceforth it would post temps 10 to 15 degrees hotter than it actually is (and if TAT is getting 87 degree temps out of the processor, according to the Temp Guide the computer should of shut down). My only thought on that though is SpeedFan says it is lower than CoreTemp and TAT by roughly 15 degrees.
Realign the heatsink? Remove some excess thermal compound?
I have not had a chance to try it yet, but will do so when I get the chance.
Interesting note: before I took off the fan to put some thermal compound on, I think I was getting 20 degree temps in BIOS. This may be the sign that I am running to hot (as now its 30 degrees and I reset the processor to stock settings).
Anyone want to provide a newbs guide to installing a fan that comes with a Eseries processor?
Ok, re aligned my CPU and removed some thermal paste as I thought I had to much (question, should, when I take off the fan, there be a layer of thermal paste on it and the processor, or should the fan have minimal amounts on it?).
Anyway, My start up temps at Tcase are 29 degrees. Tjunction hovers around 45 in TAT, so its ok.
On full load, TAT reads 65 degrees celsius and CoreTemp reads around 63. Speedfan says Tcase is at about 50 degrees, so its ok.
My question is now:
what kind of overclock can I get without increasing Vcore? I think it goes that if I increase Vcore I increase heat right? So I dont want to do that. Could I leave it at about 1.325 or 1.35 and still get temps around this with a 266 fsb instead of a 200?
I flashed the BIOS back to its original settings. I disabled absolutely everything I could find that did not result in system failure. Then I went into MIT and set the Vcore to 1.35 (hang the flashing "Voltage not optimized" thingy"). I set RAM to 2, or 1:1, and set the processor to 266.
Now it is running awesome. Temps according to CoreTemp are around 46-50 degrees on idle (Tjunction). Speedfan is giving my 32 degree Tcase temps.
On a full TAT load, dual instances, CoreTemp is giving me 70 degree ish temps, never going over 75. Speedfan never goes over 60.
This is still kind of hot, so I will lap my CPU and heatsink soon, but overrall its amazing! I have not tried a torture test yet, no Prime95, but it boots and runs fast as all get out!
