Wrong temps with Phenom II?

[Smartidiot89]

Hello! When I first installed my Phenom II 920, my temps were at 17C with Cooler Master V8, which didn't sound realistic. Now with a stable 3,5ghz clock its at 21C idle and 32.5C maxload which just doesn't seem right at all considering I am using 1.5v. Anyone know what the problem is? Cause it seems that many people can actually monitor the temperatures, and AMD Overdrive of all things SHOULD be able to read this stuff correctly?

Also AMD Overdrive doesn't seem to like my BIOS clocking <.<

First off the pic you linked shows 1.35 in both AOD and CPU-z so why are you saying that you are using 1.5v and second why would you think you need to use that if that is the case. Third at that speed and volts the temps are a little low for air cooling (unless you have a really low ambient) but they are not way off.

Dont use Amd Overdrive,uninstall it and clock in bios only....and then use k10stat to change multi when you geting a good fsb so you can lover multi in bios.

I am overclocking solely in BIOS, and I have k10stat installed.

CPU-Z shows my CPU VID, not my actually V.Core which is at 1.5v, so i find it very hard to believe those are my true temps. And it was 17C idle without any clocking and if that was true I wouldn't be sitting here with my t-shirt I can assure you

250 x 14 = 3500mhz
V.Core: 1.5v
NB volt: 1.2v (stock 1.125v)

Using a somewhat dated MSI K9A2 Platinum V.1 with Beta Bios 1.7B4. Could it be a motherboard issue that my temps aren't showing correctly?

my 920 thermo is broke. sometimes it will read in the low 20's but must of the time it reads 0 in all software. even in bios its stuck at 41 and never moves

[The Coolest]

Phenom's DTS doesn't report actual core temperature, while in K8s the DTS reported the actual temperature of each core.
In Phenom AMD only left a single sensor, placed in the center of the die. This sensor reports a reading that is not an absolute value. There's a certain (unknown) offset that needs to be applied to be able to tell the absolute temperature, so this type of reading is not very accurate, unfortunately.

My guess is that this is the best bet.Beta BIOS for the board is the probable cause for the temps reported.

[Smartidiot89]

Ok thanks for all the help yet again. Won't care to much about AMD Overdrive, but the temps bothers me @_@

Hope it gets fixed with the official v1.7 BIOS, if not atleast i know 1.5 - 1.55v is ok with high-end aircooling.

its about 20C off

[The Coolest]

Well the problem is this temp could be variable. AMD never mentioned what that offset is or how to get it.

using the temp probe on my mobo it looks like its about 20C off i'm looking at ordering a true temp probe to measure it. the asus was spot on for every other chip i have tossed in it so unlesss this chip is funny it shouldn't be to far off

[roofsniper]

finnally got my phenom II 940 in and its idling at around 45C. my phenom 9600 idled at 30C. using a zalman 9500 as a cooler so its not the best of coolers but still 45C for idle seems a little steep. i hope the sensor is off or something. anyone know of any programs that can monitor or find out cpu amps? it also jumps up 2-5C at the slightest load.

[Smartidiot89]

its about 20C off

Thanks that sounds like a decent variable, would meen I had about 53C full load with 1.5v @ 3,5ghz

[crazydiamond]

u cant get 3.5ghz stable lower than 1.5v? most people could get that @ stock V's..... might try lowering v's, i know some people were finding instability w/ too much v's

[largon]

I hear turning ACC on in BIOS can sometimes fix squirrely temp readings.

[Russ_64]

My temps look okay - using BIOS at idle gives 35c and Speedfan with load on 2 cores is 40 - 42c.

@ The Coolest - I tried the latest CoreTemp 0.99.4 but it showed wierd numbers for chip (FSB and Multi's) - I saved a SS and Reg dump - will PM this weekend.

Will try that :P Also it seems I can't find a way too change the Northbridge multiplier (if there is one?). Was running at 3250mhz when the CPU was only clocked to 3,5ghz (250x14)

I suppose you mean 2250MHz since the NB multi is set to 9 by default.

You can raise the NB multi by adjusting the HT multi in BIOS, if you set the HT multi to 10 the NB multi will follow. Strangely the HT multi will remain at 9 if you check with CPU-Z.

Yaeh sorry 2250mhz.

Now my motherboard has gone loco

I can't change anything in Cell Menu, except disable Spread Spectrum and tweak volts. If i change HTT/Multiplier/HyperTransport/memory you name it I get a blackscreen and my screen doesn't get any signals, the system won't even post. Only way to solve it is through Clear CMOS. I can still clock with AMD Overdrive without a problem, but BIOS clocking is impossible with this BIOS suddenly. It worked like a charm 2 days ago but now, impossible. AMD Overdrive isn't the most fun utility to clock with :/ Reached a 3,5ghz stable clock with AMD Overdrive thou, but I want the darn BIOS to work

Think I will wait until the official v1.7 BIOS comes to this motherboard, if it doesn't solve my issues i'll just have to get a new Motherboard i guess.

Strange, maybe it could be a problem with the 1.7B4 BIOS. I'm still using the previous version 1.7B3.

Will see if the official v1.7 will solve my problems, but might get a new motherboard instead. Looking at ASUS M4A78-E atm.

[eknny]

Sorry to hijack a bit but does coretemp show the offset applied temp of the DTS or the unapplied one for b3 phenoms?

[The Coolest]

Core Temp doesn't show any offset for Phenoms.

[eknny]

How would I apply the offset in coretemp? When i try put -20 it gives me a very large figure

[The Coolest]

I don't understand the question.
If you use -20 Core Temp will show a reading of 20C lower than what it does w/o an offset, if you use 20 then it'll show 20C higher.
