MSI DKA790GX a day of testing

[Titan7171]

Well after looking at all the threads of the different mobos out I did finally decide to purchase this mobo

Here are my findings

Pros:

excellent packaging (like most higher end mobos)
overclock cpufsb up to 280mhz so far
overclock HT link and nb frequency up to 2500mhz
overclock cpu to 3.1ghz@1.29v (stock) 100mhz increase over sb600 @ same V (but I got a good cpu)
sb750 3.4ghz@1.45v / sb600 3.4ghz@1.55+v

cons so far: (may be user error until someone steps in to help)

cpu voltage only goes to 1.45v
have to lower cpu speed with higher nb/ht speeds(270+) again due to low cpu voltage
Havent seen any difference using ACC but Im still testing its been set at +2 for all overclocking so far.
heres some validations

Ill be posting more validations and begin testing in 3dm06, superpi (Useless @3.2ghz)

so if you see something that can be modified to give me better results please add in, also how to get higher volts in bios settings.

Thanks in advanced

more pics to come

You can change a setting in AOD's configuration file to allow higher voltages than 1.45V. However, you should be careful as 1.45V is not considered "low cpu voltage" for an X4. It's rather high already.

Ok If your BIOS looks like Below then try adjusting Values@STOCK CPU CLOCKS to find how the Volts scales....

Im cleaning my loop and will check back later, This should work , Use Stock CLOCKS so you Know youll stay cool while testing


1st ,,
CPU VDD and CPUNB VDD should set or Raise VID values when VDD is raised...

The Higher the CPU VDD the Higher you Can raise your Volts while ADDING CPU Voltage (V)...

If you run the CPU @ 1.4volts the VDD should be raised to say 1.35 - 1.4VID then you add CPU VOLTAGE or needed Vcore...

2nd,,
CORETEMP will show VID value OR AOD..

I use CORE TEMP to see VID and HWmonitor to see Vcore value...

If i know im gonna use more than 1.4volts for CPU i set CPU VDD to where my VID reads 1.4vid in CORETEMP @ STOCK CLOCKS ... Then i ADD VCORE(in your Case CPU VOLTAGE(V) ).

What ever VID shows in CORETEMP as you raise value of CPU VDD the NBVDD will raise at the same rate...

So if you Raise The NBVDD it will raise the VID values just like CPUVDD does...

Im on water but i Know the Max VID is to be 1.55vid ..I use this for Both...


Remeber,,
Set the CPU @ stock CPU CLOCKS set VDD values for BOTH CPU/NB to Read 1.35vid in coretemp..(The VDD value is same for both,, if you Need more VID Raise the CPUVDD ONLY use CPU VOLTAGE(V) if Xtra Vcore is needed..


Note:
The NB VDD does not need to go above 1.35vid unless you are pushing The NB over 2400mhz...
IF you Set NBVDD higher than CPUVDD it will self adjust to NBVDD(VID values)NBVID will not adjust higher than CPUVID it will default to what you set for NBVDD(VID value) value.

If your worried about the Voltage going through the roof it wont!

Keep Vcore set @1.31v while you raise the VDD youll see what i mean.. As you Raise the VDD it should Raise your Vcore too and well above if needed...This should enable you too increase Volts above 1.45volts While using CPU Voltage(V) to dial in cores once the VID is where you want it. I believe im on the right track for ya..

790GX/3 and this Mobo adjust the same way Seeing they Did not implement VID seperate in Bioses this works for now.

I usually raise the VID to be with in .500v or my CPU vcore..

Example ,,
1.45v for CPU i would Set Default value for Vcore then Raise the VDD to get 1.45 vid = 1.45vcore...Then you add more CPU Voltage(V) to go above 1.45v.



I hope this does it..Watch your Temps,,They should not go up much or any @Stock Clocks.
Small steps and If all goes good then start Clocking that thing.

Hey thanks for the reply this cpu been up to 1.59v on my K9A2 Plat and completed 3dm06@ over3.4ghz @1.55v. cooling is more than adaquate so Im not really worried.

Is this where you change the value?<CPUVID>130000</CPUVID>, What do I change it to??

Ok I noticed this in the bios both raise at the same rate

So if you Raise The NBVDD it will raise the VID values just like CPUVDD does...

ok I been up to 2500mhz and used 1.4v

yes it seems I was doing the same thing and you are confirming it

790GX/3 and this Mobo adjust the same way Seeing they Did not implement VID seperate in Bioses this works for now.

I usually raise the VID to be with in .500v or my CPU vcore..

Example ,,
1.45v for CPU i would Set Default value for Vcore then Raise the VDD to get 1.45 vid = 1.45vcore...Then you add more CPU Voltage(V) to go above 1.45v.

this is where the problem is,once it goes past 1.45v it sets to auto as there are novalues above 1.45v



I hope this does it..Watch your Temps,,They should not go up much or any @Stock Clocks.
Small steps and If all goes good then start Clocking that thing.

Ok Ill try it this way

[Titan7171]

so how I do I get the higher voltages in AOD?? what do I change?? Is this where you change the value?<CPUVID>130000</CPUVID>, What do I change it to??

[Titan7171]

Im stuck here till I can get higher voltages



heres validation at 270fsb 3.25ghz

all stock voltages
