Tcontrol works by reading "too low" when it's below a "certain temperature point" but then "too high" when above that same "certain temperature point". The temperature point looking at documents seems to be near 55C real Tcase.

Ok, so if I got it, 55C its the "breaking" point, Tcase(real temp)<55 Tcontrol read low temps. So my readings are "low" Tcontrol=CPU 57C; Cores 48C full load, can I make an logical conclusion that my Tcase<55C?

As you can see some posts before I got photos from my system running, the white fan is at 110CFM and blow air over PWM HS, and i feel the difference between PWM/CPU, I know is far from be accurate reading, but reflects the software reading difference values, in bios CPU temp reads 28 and PWM 45.
Only the MSI runned fine 2750 @1.3v.

Well, I have some temp probes cables, and still have an K7M board with pins to connect, so if I put the probe between CPU and the socket (I have one able to insert there, just don't know here), can I read Real temp in the K7M system?

OK...... Was able to finally get the OC working on this thing only problem is that for some reason I am baffled to why the computer wont Boot with Ram at 1066 set in Bios is it the Ram or is it me? My Ram does over 1200MHZ
Thats a fact guess its me or does some Ram just not get detected when set to 1066 max value in Bios? Also from what I see my board responds better to being set through FID/DID not by CPU Multi any words of wisdom on the 1066 Ram setting in Genie Bios and why my PC wont boot with it set on that?

Modest OC
@ 2420MHZ @ 220 Bus Speed X11 Multi HT Link Frequency @1980mhz NB Frequency @ 2200mhz / Ganged Mode all at stock Voltage

Cmon fellas help a brother out and lay some info on me

[aGeoM]

Brother I did your settings with mems @1066 system booted fine.
Bios 307.

So your ram is not yet supported. KTE mentioned some time go that modules without 1066 JEDEC mode need to be prepared by the bios developers in a more manual way.
Nevermind 4-5-5-16 are the best timings i could choose in the bios in that mode, unfortunatel i could not yet reach a 300MHz ref HT.

I tried it the FID/DID way here first and it did not boot with a 13x multi using the cpu clock multiplicator worked, so I thought it's the better way.
Seems sometimes the DID's and FID's are not set to proper defaults.
What made you boot finaly, 800 mode or FID/DID?

There ya go, 2.2GHz for the NB is abit high for stock (1.25V).

Whats the word on this when even at defaults loaded in Bios with Cool & Quiet = Enabled CPUZ does not show Cool & Quiet working and consistently staying at 2300MHZ Clock Speed and voltage is consistant with 2300mhz clock speed in Both CPUZ & SG? Signs of dying chip>>?????? Anyone else see this show its head?

1066 Divider in Bios for this Ram is NO-GO Tried everything through Voltage High and low all trfc settings for all dimms at once higher trc Values NO-Dice this Ram will not work on this 1066 divider and is consistent with 3 different Bios Version too!

[Brother Esau]

Announcement:......... We all need to comprise a List of whats working with Phenom Processors with the 1066 Divider set in Bios! ......We also need to Band together and comprise A Methodical Overclocking Approach of DO's & Don'ts for this Board with Phenom Processors in Addition to a List of Fully Compatible 2gb & 4gb Ram Kits that will run @1066mhz through Bios.

I believe that this is a necessary evil and should be comprised for all to use especially for new comers to the Phenom Architecture so they don't destroy their IMC or Board due to lack of knowledge or just being a Meat Head with their approach to overclocking in general let alone throwing a very Complex Phenom into the equation

For CnQ to work you need the phenom drivers for winxp (no need under vista), CPU and NB voltages and "CnQ" must be set to "AUTO". Then choose the proper windows energy profile and the frequency should drop to 1.15GHz at ~1.05V.
Of course you can tweak the two p-states as described at page #24 here.

[Undersea]

Brother,

Do these have something to do with setting to higher then DDR2800?

Sorry I have DDR800 and a X2 so I can't tell you for sure & a M2RS 3/10/08 Bios:

[Brother Esau]

AMD Cool & Quiet ...Update:......OK gents found out what the Issue was with CPUZ , SG , Everest all showing clock frequency and voltage @2300mhz while Cool & Quiet was Enabled in Bios @ Optimized Defaults......It appears that when I installed the AMD Power Monitor Utility yesterday Evening it was reading the wrong values so I set Power scheme to (High Performance) and it still showed the same Frequency Attributes Irregardless Guess its a Vista /Software Issue.......Big surprise!!! So I figured I would Uninstall it due to the Fact that it does not register the values correctly .......So I guess by Now its Apparent that I did not set the Power Scheme to (Balanced) Prior to uninstalling it

So I have reinstalled it and low and behold Power Scheme is still at (High Performance) and have now set it to (Balanced) and Houston we have lift off......All Systems ...Normal

The Ram Issue is Pending and don't expect that to change until changing out Ram Sticks!

[KTE]

ok, I give up. I was lucky not melting the board when I did 2900Mhz @1.53v

You really can't expect any IC which is above 20W TDP max to run cool on air with that voltage now, can you?
Yep, it'll be idling (no CnQ) above 45C alone.

KTE, OCing in my point of view, isn't lowering nothing, more CPU/NB/HT/MEM MHz @ the most stable configs, finding the balance (G spot ) it's my gold, for 24/7 use and smooth as silk gaming.

Same here but that's different to how you find the max oc for a CPU. I work backwards from max to find max stable

That's why I'm a litlle frustraded with DFI compared with ASUS/MSI, she's cold like Artic waters, maybe that's why I'm getting so low temps.

The board makes the CPU cool?

This is a board limitation I guess, since your boards alter the VID and changing VID means CnQ won't work (won't drop). If you're using boards which change volts only, CnQ should work with any voltage as long as you set default VID.

Undersea: MSI 790FX and GBT 790FX/X run 1066 mode fine for a while now.

Fifty lashes for me I promise when I get my Phenom I will re-read that monster thread.

So when do we see some benchies Brother?

KTE..., my friend..., I never doubted about your knowledge, far superior and wider than mine, if you said so, I believe in you and learning from you. But I have the feeling that you are missing the ability of the HS to absorb/dissipate the heat, and cooling the IHS on your equation.

Same here but that's different to how you find the max oc for a CPU. I work backwards from max to find max stable

Me too, but for all system, not only the CPU.

The board makes the CPU cool?

Was trying to make a joke, since I haven't realize if I found the "G-Spot" on DFI for be so "cold". Sorry for my "Beach" English, only 2 years English on High School, ages ago.

Now, seriously I just order an 9850BE for 199 euros, expect to arrive by the end of next week. It's available in Germany since yesterday.



Edit: Just saw my hwbot rank.

I have 2x1GB SuperTalent T1000 and it's working fine with 1066 divider. I was able to push them to 1200MHz (225MHz FSB with 1066 div.) with the latest BETA BIOS.

[justapost]

Tried another raid config:

Raid0 250GB with four hd's and 850GB Raid10 with the same hd's.

Old Driver/F6-Driver
Raid0


Raid10



Raid10 performance seems to go down on average and up on burst with new raid drivers. Over all the CPU utilistation goes down to ~50&#37; of the old results.
Also if you compare the results from the 2GB raid0 with the 250MB raid0 you'll see that the average goes up ~10MB/s.

[KTE]

Ok, so if I got it, 55C its the "breaking" point, Tcase(real temp)<55 Tcontrol read low temps.

That's a guess by me and that's only Tcase (center of IHS). Tjunction (internal diode) temp. is higher. But yeah 55C seems very close to what it is. The diodes in k10h also have an errata where they read too low temps.
You just have to use common sense and basic physics knowledge to discern whats correct and not; 1.4V/155W on a 1.23V/95W TDP chip is going to be very high load temps. In the 70-75C region Tjunction with a TRUE and 2x 105CFM Deltas, 20C ambients, which is not far from the throttling temp.

Brother, you'll need to read quite a lot for Phenom, it 'aint that simple as X2/C2. Spend some useful time now and quit messing around


Achim and aGeoM should know all there is to it without you needing any other material.
Drop your NB to 6x and the MEM to 667 mode, blast coolers on full then try oc'ing Phenom.

When targeting some hwbot's scores then I clock someting down to achive it. For me Phenom in some way isn't different from X2 or K6-2, only have more variables to play.
That's why I'm a litlle frustraded with DFI compared with ASUS/MSI, she's cold like Artic waters, maybe that's why I'm getting so low temps.
