Memory Voltages

[coxmaster]

Finally got my motherboard back.. got it all put together and running great. The only problem(s)..

My memory will not change to the correct voltage/speeds. I have set the memory to 2.1v in BIOS but they still say 1.8 when checking with CPUz. I also noticed it is running at 400mhz.. rather than 800mhz.. so there is actually a need to get them up to speed.

I also noticed, my CPU temps seem a bit high at about 48ºc for CPU 40º for Core0 and 41ºc for Core1 Reading from Speedfan.

Are those temps ok? And how can i force my ram to the right speed.. Its OCZ Platinum btw

Try clearing the CMOS and try resetting your memory voltage again.

As for CPUz reading your memory as 400Mhz, don't worry about that as its correct as you are using double-data-rate memory(DDR2 in your case). Your memory is clocked at 400MHz with an effective speed of 800Mhz hence the term double-data-rate.

What Tjunction does CoreTemp show? It should say 100C.

[coxmaster]

Alright, Bios is showing my RAM at 2.1v so thats right. Maybe its just CPUz thats wrong.

As for the 400vs800.. dohh, i shoulda known that from A+

Im workin on disabling driver signing so i can run CoreTemp, so i'll have that posted up in a sec!

[coxmaster]

Alright, CoreTemp is showing this: http://img180.imageshack.us/img180/1018/corefx4.jpg

The CPU is under about 25% load..

[werty316]

Are you using the stock cooler that came with your CPU?

What are your idle and load temps?

[coxmaster]

Yes, im using the stock intel HS and fan.

I just ran some tests and the load temp is 59º for Core0 and 61º for Core1

That seems a bit high to me....

[werty316]

Well case airflow as well as the ambient temperature could be a factor as to why your temps are higher than expected.

[coxmaster]

Ambient temp isnt the problem.. its about 68ºF in my basement...

According to SpeedFan my AUX temps are only 26ºC Which is pretty good. My GPU temp is only 42ºC according to GPUz.. and thats with the fan nearly off.

My CPU was much cooler before i got my replacement mobo.. what could cause this difference.

Also, my fans right now are flowing Front to back, so the PSU fan and rear exhaust are both sucking air from above the CPU. Should i reverse the rear fan so it blows onto the CPU area?

[werty316]

The PSU fan as well as the fan at the back of case are usually setup so they blow out the hot air while any front case fans will blow air into the case so I wouldn't change the orientation of the fans.

Try seeing what kind of CPU temps you get with the side panel off of your case.

[srpeters18]

Those temps are actually pretty normal for the stock HSF. Are you overclocked? Also, if you use SpeedFan, the CPU reading is correct but with the newer processors it reads all the cores 15 degrees cooler. If you click on the configure button and go to the advanced tab there is a drop down box. Select the one that will display both cores and set the temperature offset as 15 for both cores and don't forget to click the box that says "Remember it" on both as well. Now your speedfan readings should be the same as your coretemp readings, and you get the other speeds and temps as well.

[coxmaster]

Taking the side panel off didnt make any real difference. I would assume the fan on the side helps atleast a little with getting air to the CPU.

@srpeters18: The temps were about 10º cooler before changing out the motherboard.. It is currently overclocked.. sorta. 2.33ghz-2.36ghz. Not what i would consider a "major" overclock. So if thats about a normal temp i shouldnt be concerned then? Or would it be worth my time to reseat and put on a little more thermal compound?

Or less compound, maybe he has too much.

[coxmaster]

That actually could be the case Miker..

I used more this time than before. Ive never really though about how much i need. I put a dab of it on which was a little bigger than a pea. Is that too much?

[srpeters18]

Yeah, too much will have the same effect as not enough. Should be more like a grain of rice. Assuming you're using arctic silver 5.

[coxmaster]

Hmm.. well it seems probable that i have too much then. Its not AS5 though, its ZeroTherm.. they didnt have any AS5 when i went to get it.

Supposedly ZeroTherm is nearly as good though. So i guess i should clean the heatsink/cpu and reseat right?

[srpeters18]

That's what I would do.

[coxmaster]

Alright, i'll go back and reseat the CPU ASAP.

As for the memory.. it still wont go above 1.8v... Is there anything other than BIOS i can try to get it to where it should be?

Will manually setting the timing work?

[coxmaster]

Alright, got the CPU reseated with less thermal.. wow that made a difference.

The CPU is running at 37ºC while folding.
Core0=40º
Core1=42º

Still the same problem with the memory though :(

[werty316]

Didn't you say that the BIOS is showing your memory as set to 2.1v?

CPUz doesn't show your memory voltage. As far as memory settings goes CPUz shows the voltage and timings of your memory if its programmed with a SPD spec.

I think you are confusing your memory SPD specs to the actual settings you have them set to.

EXAMPLE:

This section in CPUz doesn't show what your current memory settings are as these are the SPD settings that are programmed into your memory.

[coxmaster]

Ahh ok, so in CPUz under the SPD tab it shows 3 different frequencies, each with different timing, but all with 1.8v. That isn't actually what the RAM is running at..

Well i guess thats good then. All i need to do now is change the timings to 4-4-4-15 rather than 5-5-5-15.

As for command rate, do i want T1 or T2? Or does it really make a difference?

As you can tell, RAM is one of the few components im not experienced with.

[werty316]

You shouldn't have any problems running the Command Rate at 1T however if your system is unstable try setting it at 2T.

Performance wise on an Intel setup, the difference between 1T and 2T is minimal however its quite opposite on an AMD rig.

Generally you want to run it at 1T but sometimes thats not do-able like for example if you have all four memory slots filled where in this case you have to use a command rate of 2T.
