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.

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!

hehe gratz...

a well Brother Esau, i got the same problem with the phenom 9600 BE that i can't set my 2gb OCZ Flex XLC (PC2 9200) at 1066 it will just not boot,
800 works though but isn't stable

Still working on 667mhz but it works so i'm just waiting for a better bios.

still on bios 11/22/07

So the MSI board and I know the Gigabyte boards have the same problems with 1066.

Have you all tried the new bios?

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.

[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?

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.

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?

[Brother Esau]

Sorry man just moved back to the East Coast , 2 months ago been in my new place 1 month cats been sick Bios Website to get Designed and Built just allot of Sh**t to do in general

No problem. I've waited this long I can wait a little longer. Man I can't wait to get a phenom.

Where you at? I'm in Jersey.

New Jersey heh?? Oddly enough I am New Jersey Born & Raised and grew up in Tinton Falls next to Red Bank Exit 109 OFF the Parkway Live in Wilmington, NC now and very happy to be back home on the East Coast after 5 long years and I lived in Wilmington North Carolina 7 years ago and its really nice down here and I am glad to be back

hehe found it both thank you.. i hope there's some tests at my house next weekend under water cooling with that great chip

Having four WD 500GB RE2 hd's here atm so it was time to try a raid0 with them.

Results:

Old Raid-Drivers (07/07)



HDTach:
Burst: 227.3 MB/s
Rand. Access: 12.9ms
Avrg. Read: 140.3MB/s

HDTune:
Burst: 108.4MB/s
Rand. Access: 11.2ms
Avrg. Read: 146.4MB/s


F6 Raid-Drivers (08/07)



HDTach:
Burst: 246.4 MB/s
Rand. Access: 13.0ms
Avrg. Read: 150.7MB/s

HDTune:
Burst: 113.6MB/s
Rand. Access: 11.1ms
Avrg. Read: 153.9MB/s

EDIT: Also i inspected the F3xA0 PCI register which holds the information in bit 29 which voltage mode is used (1 = slam mode, 0 = step mode).
I expected step mode in CnQ but it is also slam mode here.

[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% 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.

[Oese]

150mb/s
you guys use vista or xp?? wonder if raid would work like that here as well.. THAT would be NICE

1066 booting.

Now i just spoke with my good friend Gary who is a little more upto date with phenom testing that i am regarding booting at 1066.
he explained the new bios files for the MSI, GBT and Asus allow 1066 to work easier that the DFI, this does not mean it won't work though.

I asked if tRFC at 195 was needed...it's a MUST setting

I asked if tricking the board with timing and voltage before speed helped...seems it is needed in some cases..Like with the DFI.

I asked what timings did you have to run, he quoted the 6's (i thought it would be), so try 6-6-6-18 or 5-6-6-18

So if you are looking to test whether 1066 works, go to 2 dimms only, set 6-6-6-18 tRFC to 195, relax the subs and set 2.0V...this all at DDR800. Reboot,
Go back to bios and set 1066, and try to boot again.

I am trying to get a 9850BE to resume testing, when it arrives i will post how and if I get it working.

[Brother Esau]

God Bless ya Tony Good to see you and thank you for your continued assistance

Ok I am going to give this rig another shot, after two bad bios chips on the board. I have read a ton of things about how the general population is stuck at 2.7ghz, but then I read some stopping around 2.9-3.0. I have read something about the northbridge speed being a limiter? Its the stuff in my sig, I have it in my basement where the ambient is about 18C, and I have tons of air flow in my case. I had my 5000x2 BE running at 1.60v and still under 60C at full orthos load.

So what I am wondering is what are the basic bios settings I need to be looking at beyond fsb/voltage/memory timings. I have heard about this nb speed or nb multiplier?? What other things do I need to consider that I didn't have to with my old X2/590sli setup?

Hahaha .........Not as easy as that my friend you are going to have to re learn AMD Overclocking now that you are on K10 that is a must and you cant get around it!....Start Here and re read it a few times and be patient ........DFI UT 790FX-M2R / Phenom Overclocking
