Has anybody gotten an AMD Phenon II x4 965 BE to work properly on an ASUS Crosshair AM2 motherboard? - Page 5

GREAT NEWS!!! Its supported.
After more reading : the Crosshair is single power plane, not dual power plane, because of that the bios stuck it to the lowest performance mode (200Mhz x4).
Tools like K10Stat and Phenomtsrhing try to CHANGE of performance mode, or try to apply the settings on the highest performance mode, which change nothing.
Using CPU Tweaker 1.4 (latest version doesn't work!) it's easy to set the multiplier and reach 3.2GHz (click on "CPU" tab, remove the "/2"->"none" then up the multiplier to 16).
Will need further tweaking to set voltage and stuff, but basically, it works !! no need to spend more money smile.gif

...but, V-Core 1.212V is the maximum reached to allow booting, CPU tweaker fail to modify it, is there another soft to do that ?
For now it's unstable.

edit: its stable at x14 (2.8GHz) using 1.212V, CPU-Z is displaying a constant 12.000V. Will maybe upper to x15 x16 to test, or maybe upper the system clock a bit (but temperature varies brutaly between 42/47/52 while building on all cores, so I'll keep safe things).

I'm seeing this alot, but it is incorrect. My sig rig is running a m2n sli dlx (AM2 board) and a Phenom II x4 business class (locked multi) 955.

All thanks to the M2N club, and Gyro was a HUGE help.

Overclocks to 3.6ghz before vrms shut me down also. thumb.gif

Can you change voltage in bios?

Those temps seem pretty high, especially on such a low voltage; also consider adding some cooling to your VRM area.

Done! Stable at 232x14 1.218V, nearly equals the cpu spec. highest limit. which explain why they didnt release proper support.
mail me if you want all config screens : l_skarab at hotmail dot com

edit: not stable, lowered to 212x14 1.218V, it looks it wont be stable upper 3GHz.

Happy to reach the 3.2GHz, maybe I'll decrease it a bit if that's cause temp/stability problems (have a cheap cooler but not the standard).
Anyway staying under 60°C seems acceptable looking other posts.

But, something is strange on this board, it's not dual power lane, but the cpu alim is 8 pins (not 4, there was a protector on the 4 other pins that I removed to put a 8 pins alim, before removing my old Athlon X2), maybe it's not for cpu only don't know...

Ok, 212x14 1.218V (2.9GHz) is stable with highest usage.
Temperature is fine too.
Wont try to go 213. gg smile.gif

It was a high price MB, and is life time seems really high, that's why I prefer to keep it till it dies.

(edit: but your 1.3V isnt reachable on my board, from the bios at least, it wont boot)

FWIW i have a $3 92mm CPU cooler with a decent MX2 application and I get those temps above after hours of prime95. It is a Coolermaster TX3 rebrand refurb i grabbed on Amazon. Good deal on that one... shouldve bought a few more.

You can do better on less volts. Maybe reseat the cooler?
