My idle temp is 47C with Core Temp 0.96.1 on IP35 PRO
Is this right?

Probably not.
I'm getting 28c and 21c? so i don't think its reading right.

[Zeus]

My temps don't seem to fluctuate half as much as my Conroe did, both cores are steady at 37ºC idle, my conroe fluctuated all the time between 34 and 37ºC and always had ~2ºC difference between both cores.

Temps seem right to me, i'm using coretemp 0.96.1

Ok, I'm screwed. What BIOS are you using?

[deathman20]

I get that screwed reading as well.

I get 42C Idle temp but it creaps up after I put it under load to what seems to be proper tempature.

I used the 14 Bios temp didn't seem to move at all and Beta 16.04 bios worked but as mentioned stayed at 42C til I moved past that tempature I think.

Have the same setup. What are your temps idle and load?

[GOESA]

Haha guys thats nothing,

Mine is at 58 always, but does not get hot at all, under load it gets 60-65celcius, I think its buggy reading in the chip, does not bother me.

Wish i knew, i think they're about equal.

How's yours?

I almost have the same setup like you.

Asus Max, WC with Fuzion, crucial 8500, e8400.

4230G on 1.35V orthos Load at 55 degrees? Are these normal temps?

What were your load temps (using what sw?) with a orthos load or something?

[unclewebb]

CoreTemp is the only program guaranteed to be reading the value of the on die digital thermal sensors (DTS) within the Intel core CPUs. Any change in the version of the bios you are using will not change what CoreTemp reports.

You can use CrystalCPUID to read Model Specific Register (MSR) 0x19C directly. The data contained in bits [22..16] of this register is a 7 bit number which shows you how far you are away from TjMax. CrystalCPUID also lets you select which core you are reading the DTS data from. This same data can also be displayed using CoreTemp when you go into the settings and select "Show Delta to Tjunction max temp."

CoreTemp then takes that data and plugs it into this simple formula:
Absolute Temperature = TjMax - DTS

For the E8x00 series it is assuming 105C for TjMax.

Check out post #210 to learn how to test temperature monitoring software.

In previous testing of the dual core Conroe processors I found CoreTemp to report absolute temperatures very accurately from about 45C to their TjMax of 85C. In my opinion the DTS sensors are not accurate at low idle temperatures and will typically report too low. Intel designed and calibrated the DTS sensor to trigger throttling at TjMax=0 and CPU shut down about 20C after that but has never publicly documented its use for reporting idle temperatures.

GOESA: I think its buggy reading in the chip, does not bother me.

Another user reported having a cpu where the DTS on one of his cores was stuck at a fixed value. It could go higher under full load but not any lower. It would be highly unlikely that both cores were stuck at the exact same fixed lower value. If anyone sees that then try turning down the core voltage and MHz to default or lower and see if you can force the temps lower. If it still doesn't go lower at idle then you should return it. If it overclocks like a MOFU then I'd keep it!

Just got my 8400 today

I have about the same setup.. Asus Max, 8500 crucial, with only a cpu WC custom system D-tek fuzion.

Running 9x475 with 1.33 Vcore. I am getting 53 with 54/59 on cores using everest on Load with Orthos!

What are your other voltage settings and what are your load temps?

[Praz]

As long as you're confident that temperatures are in check, out of the way readings are probably just that. A lot of these chips are reporting erroneous values for temperatures.

Anyone wanting to return their CPU because of temperature readings need to do it through the place of purchase. Intel does not recognize 3rd party software as a valid temperature reporting method for RMA.

[avrionis]

Look at the description, it said 45nm ready, but sometimes you do need to flash the bios.

I am not sure if they will overclock well with 4 sticks of ram but with 2 sticks there are plenty of great results.


Edit: E8400 @ 4.32ghz with 1.4v

What were some of your load temps?

[Bail_w]

What were some of your load temps?

With 1.4v and my watercooling setup, my load temp were around 60 and idle at 42. I remount my block couple times already, maybe i should remount it again.

[Blackwhite]

Did anyone try run E8xxx on Abit IP35 - I heard it doesn't support thi CPU yet.

[Viss]

Started playing with E8400 #2, again Q746A328. Not that much to show yet but start looks promising.

Hehehe , you won't take out the mobo like i told you , but you did something much better instead

Nice clock

[Garrett]

Damn loc.o... or should I say Viss?

Exact same stepping but even booting @ 1.28v @ 4.0ghz welcomes me with a BSOD... could it be the mainboard? (P5K)

[doom_st]

Have the same setup. What are your temps idle and load?

-40c

[CERO]

Got a E8500 on my way, will get it on tuesday next week probbly, looking forward to it.

[Devious]

Stayed at work till 6:30pm waiting for Advancetec to deliver my E8500 ( should finish work at 4pm ) Rang them 3 times over the course of the day and they kept saying its on its way.


Thats no benching for me this weekend... arse!

[GLENBOY]

hiya devious i thought i'd get mine today from advancetec as well so its going to be monday then , we hate waiting

It could be your ram? maybe update bios? try to play with it first then attempt to hit home run later?

how hot is the cpu? i can't even guess my temp idle 42/47 load 67 on highend water (42/47c @ stock 42/47c @4.1) and so on...... remounted 2 times already, i can run orthos 4.1@ 1.296v but since i don't know the temp is that max for now untill i know more.
