Phenom II x4 955 BE. default and OC Voltages?

[Hendaia_xg]

Hi, I have this cpu on "asus m5a97 evo r2.0"
The default 3200Hz voltage is 1,368 (high load)
If I change the multiplier (in the BIOS) the voltage increases automatically and It is not posible(well im a noob) go lower, I can go higher only.
Righ now I have @3611Hz and the voltage is 1.452

Im asking for help because Im reading that those voltages are crazy high. 1,360 is the default value

You should be able to take manual control of your voltages in the 'Tweaker' menu, or by using the AMD OverDrive utility.

If you have the serial number of your CPU you may determine the 'stepping.' C3-steppings will OC higher with less volts, and are identified by the last digits of the serial numbers -- likely ending in -MBOX for a retail chip.

I have a MBOX one stepping 3, revision RB C3.
And yes I can tweak the voltage (sure I could, sorry im dumb)

Well I leave the OC like that (I hope its a decent setup because Im a noob, may I should decrease the voltage)

Current CPU speed =3636 MHz
Target CPU speed = 3600 MHz (I tried to set this higher than current, but current go higher automatically after a reset, even using that autoOC option of the bios)

Memory Frec: 1199MHz
NB= 2025MHz
HT= 2025MHz

CPU offset Voltage 1.4520

With a C3-stepping and your motherboard, you should be running 3.8GHz or so at 1.3825v VCore. Try to keep the volt-offset to a minimum (+0.025v would be wonderful). You may use the volt 'sliders' in AMD OverDrive (AOD) to test within Windows -- there is also a slider for the CPU multiplier.

Higher volts = more heat. Drop the VCore as low as possible while maintaining stability, especially with the stock cooler. Always test for stability and HEAT (AOD will give you a 'thermal margin') The VCore moves in +/- 0.0125v increments.

You should be able to boost your IMC/NB to 2400MHz at 1.25 NB volts (keep your HT as close to 2000MHz as possible). This will greatly increase your memory bandwidth and reduce latency.

Are you running 2200MHz RAMs?

Thank you very much. I will need time for that, Im very noob so I go slow. But this is a great basic info. Thanks!
My RAM is:

4.096 MB Patriot Memory DDR3 @ 800 MHz
4.096 MB Kingston DDR3 @ 667 MHz

Both are 1600, for some reason the kingston is capped, or its fake, I dont know.

No worries. We just have to make sure we are both on the same page.

RAMs are 'double-pumped' so 800MHz x 2 = 1600MHz. Being that your RAMs are mixed (dogs and cats living together!), memory will normally 'dumb-down' to the slowest speed and timings. On occasion a system will not manage this very well on its own. No problems, though, as you may set the speeds and timings manually in the BIOS so they work their best together.

In your RAMs documentation it should list your speed and timings. Simply list the specs of each other side-by-side and compare them. For an exhaustive explanation, check this out from Hardware Secrets.

The memory timings are given through a series of numbers; for instance, 4-4-4-8, 5-5-5-15, 7-7-7-21, or 9-9-9-24. These numbers indicate the amount of clock cycles that it takes the memory to perform a certain operation.

You simply take the 'highest' number from each stick of RAM and use that as the timing for both sticks when you manually enter the information in the BIOS.

Then, those cats and dogs will be making sweet, sweet memory love :lol:
