swishamane: if you can cold boot @ those settings then you got one hell of a chip, i'm running 1.32v through my cpu/nb to get it stable @2800 but im also running the cpu @4.7 so some of that added voltage was to help stabilize my cpu clock, but still your volts @ those speeds are pretty impressive.
Understandable. Wanted to make sure....
I just alomst sounded like you were making them one in the same or related... Sorry about that...
One thing that I realized about BIOS 1.51b is that when you set the HT Link Speed multi to auto, it gets set to whatever the CPU-NB multi is set to... but when I set my CPUNB to x15 for 3Ghz and my HTLink to Auto it showed 3ghz as well in the BIOS but in CPUZ it showed as 200.... (Not 2000)
Okay gentlemen..... These are my findings...
Note: (Just we're all on the same page here... Using the term cold boot I'm referring to shutting the PC Down, Flipping the PSU switch to off and Draining the caps by holding the power button for 2+minutes)
-Board revision: MS-7577REV 1.0
-CPU revision: 955 C3
I'm running BIOS 1.84beta right now and @ CPUNB Multi set to "x14" for 2800Mhz I cannot cold boot no matter what I do. CPUNB multi @ "x13" for 2600Mhz I'm good as most of us are!
BUT, I starting thinking about the fact that I can "cold boot" @ 2800 (x14) on this board with BIOS 1.51b... What I did was change the CPUNB multi down to "x13", then first bump the HT ref Clk to 215 for a CPUNB freq of 2795Mhz, booted into the OS, shut her down....... She cold Booted fine, right into the OS... So I push HTRClk to 218 x13 for CPUNB of 2834MHz and warm rebooted into the OS to make sure that it was good to roll with programs and booting. Sure enough, I shut her down and waited.....
She cold booted fine @ 2834Mhz... It has to be something with the Multiplier on CPUNB. Now I'm sure that it's related to the BIOS, which is my first and most powerful thought being that I can use the "x14" multi for the CPUNB with a cold boot fine... There is no other explaination for it. There is no real pattern with anything else EXCEPT this one thing... Which in my opinion has to be the issue...
AGESA is a bootstrap protocol by which system devices on AMD64-architecture mainboards are initialized. The AGESA software in the BIOS of such mainboards is responsible for the initialization of the processor cores, memory, and the HyperTransport controller
So that being said, if you go to the MSI website and look at the changes done to the BIOS, AGESA was FIRST changed in the OFFICIAL BIOS 1.5. BUT then it was Change again STARTING @ 1.6, then 1.7 and 1.8 as well. So IMO there has to be some sort of Difference in the Coding of the Generic Encapsulated Software called AGESA....
Okay, good NEWS!
I set my HTRClk to 231Mhz Which gives me:
CPU- 3811Mhz @ 1.42v (BIOS)
CPUNB- 3003Mhz @ 1.38v (BIOS)
Ram- 1540Mhz CL6-6-6-18-24-1T @ 2.02v
HT Link- 2079Mhz (Stock v's)
And to let you all know.... She does "cold boot" @ 3003Mhz CPUNB.... So it may not enable the use of the multi @ higher than "x13" on a cold boot but Hey, at least it can cold boot @ over 3ghz CPUNB!
Hope this helped!Edited by Mastiffman - 2/7/10 at 9:34pm
