A75A-G35 (Llano) no CPU Voltage?!

This MB it really bad. In BIOS, there is no CPU Voltage setting. What does it mean? Only NB and SB Voltage? Completely useless because no OC is possible. I hope they release new bios or do something about that

You call a low-profile board "useless" because it is not suited for overclocking? When you want overclocking, why did you not buy a board that is not low-profile and actually more suited for overclocking?

How to increase cpu voltage on A75A-G35?

Please tell me how to increase cpu voltage on A75A-G35(I changed pstates in BIOS but voltage not changed!)? and then tell me range of voltage in 1-7 Pstates?
Thanks.

Q: I cannot adjust the CPU Voltage on my A55/A75 motherboard?
A: Due to a hardware limitation on this platform, you cannot adjust the CPU voltage. However, you can adjust the NB voltage which is the same on this platform.

The NB voltage setting is below the "Advanced DRAM Configuration" and the only way to increase a cpu relating voltage on that board.

A75A-G35 Overclocking issues

Hello Everyone,
I put together a new Llano rig not too long ago with an AMD A8-3850 APU, 8GB GSKILL Ripjaws X DDR3 1600 memory, and the MSI A75A-G35 motherboard. With the stock BIOS, 1.0, I could use the OC Genie function to quickly overclock my components. I updated to the latest BIOS because it fixed a problem with the CPU fan failing after sleep mode. So now I have the newest 1.4 BIOS available and I try using the OC Genie function and it fails. The computer reboots and says that the previous overclock failed. I have tried tweaking the settings myself but it still gives me the same error. Sometimes it even gives me three beeps before POST indicating that the overclock failed. When I reset to defaults everything is fine. Keep in mind, I do not have a separate video card installed but do have two PCI cards, a sound card and wifi card to be exact. I've tried everything I can think of. Does anyone have any ideas of why it won't overclock anymore? Or am I just out of luck?
CPU: AMD A8-3850 Llano
RAM: GSKILL Ripjaws X 2x4GB DDR3 1600
PSU: Cooler Master 500W PSU
HDD: 1TB Hitachi Drive
GPU: None installed
Expansion cards: sound card and wifi card
ASUS DVD burner
Thanks,

That ram is supposed to be a 9-9-9-24 timing. Most boards default to much lower. I had the same situation recently. Also, the auto oc tried to fry my memory by boosting the voltage on it to 1.7 when it ran fine overclocked at 1.5.

***Strongly recommendation: For AMD platform, please follow the voltage/timing as specification to stabilize your system instead of select AUTO/Default.

[Solved] A75A-G35 gives no video signal over HDMI, resolution over DVI limited

Hello community,
following problem: I have been using my A75A-G35 board with an A4-3400 Llano APU, the APU has been connected to a 19" BenQ FP91GP monitor via a DVI cable. I got its maximum resolution of 1280x1024 with no issues.
Now I have purchased a 24" Dell U2415 monitor with a maximum resolution of 1920x1200 and wanted to connect it to my computer. However, I got stuck:
1. I get no signal whatsoever using the HDMI output and a HDMI>HDMI cable. I have tested a different computer and connected it to the Dell with the same cable successfully, so the cable and the monitor should be fine.
edit: Disregard the following as the problem with the DVI cable appears also with the other computer. The problem is therefore just the fact that the HDMI output of the board doesn't work!
2. I get a signal with a DVI>DVI cable + DVI>HDMI adapter. I can access the BIOS, the boot manager and see the boot screen, however once the desktop should be displayed the screens turns black and the monitor keeps switching to standby and back on again, the screen staying black all the time, however. But before installing the driver package (for chipset and video, downloaded from the MSI website), I could see the desktop with a resolution of 800x600. Also, if I boot into safe mode, I can see the desktop and increase the resolution up to 1280x1024. Higher resolutions up to 1600x1200 are available, however selecting any of them results in severe screen flickering.
3. If I boot my Linux install, I have almost the same behaviour. I see the boot messages but then the screen turns black when the desktop should appear. However, if I connect the old BenQ monitor to the VGA port, I get a signal on both screens, however both screens have the resolution 1280x1024 and I cannot increase the resolution of the Dell, because if I try to, the screen turns black again. Lower resolutions than 1280x1024 are possible, though. Note that the "second monitor trick" does only work with Linux, with Windows I get only a black screen on both monitors.
As a side note, the DVI cable I'm using is a DVI-D single link, so the maximum resolution it supports is actually exactly the resolution of the Dell, 1920x1200.
Thanks for any hint,
Photon

your welcome!
when you said your problem and the symptoms I thought that board sounded familiar as alot of people when it first came out that we had to explain that to them so I had a look and yes it had the jumpers to switch ports for its digital display display signal to be routed to another port so i thought that was the cause!
have fun with your board now you have it in HDMI mode!

A75A-G35 will not boot

Hi
Have the motherboard A75A-G35 (MS-7695 ver1.0 printed on it)
It was working without problems for a few month. Suddenly it stopped to boot. Hangs with BIOS check code (right-bottom corner of screen) - 99 (Super IO Initialisation?).
Tried to clear CMOS - no results.
Tried to boot with only one memory module installed - no results.
When plug-in PCI card: ST-Lab A142, Ultra ATA /133 (Silicon Image Sil0680) (for my PATA devices, not connecting them) - it hangs with status B2 (Legacy ROM Initialisation?)
When plug-in PCI card: 3 Port FW100 Firewire IEEE1394 Agere FW323-03 (alone, w/o other PCI-cards plugged(usually they are plugged both)) - it stops with 99 code too.
I don't know which status is earlier 99 or B2, but I thinks it doesn't matter in my case, because halts w/o any cards too.
PC speaker beeps once(short) as usual, keyboard indicators blink once(after beep) as usual to.
Even tyied to boot w/o keyboard.
Tried other Power Supply Unit - no result.
What I can do to resurrect it?

A75A-G35 C6 mode issue

Hello all,
I have an MSI motherboard with following specs:
Rosewill Stallion Series RD500-2SB 500W ATX12V v2.2 Power Supply
MSI A75A-G35 FM1 AMD A75 (Hudson D3) SATA 6Gb/s USB 3.0 HDMI ATX AMD Motherboard with UEFI BIOS
AMD A8-3850 (using integrated APU graphics)
2 x 4GB DDR3 G.SKILL Ripjaws F3-12800CL9D-8GBRL @ 1600Mhz
1TB WD Blue Caviar SATA HDD
80GB WD SATA HDD
SATA DVD-ROM drive
I have a problem similar to one another person has with the A75A-P35. Windows (regardless of the version used) reboots at random times. I have tested the memory and it is good. So are the HDDs and DVD drive. Apparently, I've run into the same issue that when C6 mode is enabled, it will cause Windows to randomly reboot without any warning or Windows Event information. All video ceases and the screen goes blank.
I've tried re-flashing my BIOS thinking I had a bad flash, but it didn't work. I have since disabled C6 Mode. I haven't had any further stability tests. But it always seems to happen when the CPu seems to be trying to "sleep". Any suggestions?

MSI A75 G-55 CPU Voltage

not sure which mode should i post
this is first time I use msi mainboard and never see this bios style before
I want to know which mode can i adjust cpu voltage.
i've fond only this mode named Pstate but itsn't working.i was try changing it to auto pstate1 or pstate7
but voltage still at 1.352v both clock at 2.7GHz and 3.3 GHz
now i'm stuck at 3.3Ghz because i can't increase it. Thank for help

Thank you
but I've found this pic
It's MSI A75MA- G55 Bios having CPU voltage under Dramconfig
then this is My Bios MSI A75A-G55 doesn't have this mode.
Wondering if I flash bios to newer version from 1.1 to 1.6.Will this mode show up or not ??
So I might chang it to A75MA for Overclocking right ??

Problem with CPU Voltage

Hello
I build new PC with:
i5-760
Noctua NH-D14
MSI P55-GD65
G.Skill 2x2GB CL7 ECO
Antec TruePower New 750W TP-750
TwinTech GF 9600GT
I have problem with CPU voltage as even when I set it for example to 1.201v in bios, under load it overshot to 1.256-1268. The best is when I oc`ed cpu to 4GHZ and set voltage in bios for 1.30v it overshot for 1.45v+! Not to mention that temps are skyhigh from that. It doesn`t matter if I try to put BIOS Vcore on 1.1v on stock because under load it still rise to 1.16. I turned off all eist, c-state, turbo boost, phase led and switch phase, set vdrop to low and still something is wrong here. I updated the bios under dos from USB stick to newest 1.9 version in order to update CPU micro code without error and it not helped. I want to know is that even possible to fix or should I RMA MB or CPU.
Minor problem is with sysfans as they power on for a second and turn off instantly to start working again when I see list on devices in post. After rebot when my monitor is switched off it takes something like 5 sec to power monitor on and another 5 to show bios, is that normal?

I have similar issues, it's hard to tell which measurement is the most accurate, there are 2 different measurements in the control center that don't match up with the figures set in the bios. The only way to be sure would be to get an expensive accurate multimeter but If you're only interested in running a stable overclocked computer without knowing the exact figures then get the computer running stable and lower the voltages until it starts to become unstable with prime95,
Or you could work the other way round, set the voltages so it boots but doesn't run prime95 for long, then raise the vcore and vtt one at a time until your happy with the length of time prime95 runs without errors. I'd be happy with 24 hours, I seem to remember errors creeping in at around the 9 hour mark on the setting below what I have it set to now.

How to get higher cpu voltage during load when using "auto" with P67A-GD55?

I have a little question regarding cpu voltage: When i set vcore to "auto" i get a nice low voltage when idle but during load i only get 1.264 max and that is to low.
Is there a setting to increase the voltage during load and still have the cpu vcore set to auto?
Thanks
System:
P67A-GD55 with 1.8 bios

Quote from: Bernhard on 01-May-11, 15:25:22
OK, so you are able to set your CPU voltage manually. You need to consider that the auto voltages will compensate only up to a certain OC level, after which the user usually has to do manual adjustments. This auto compensation differs for each hardware combination. As HU16E suggested, try low VDroop and see if it helps. The other alternative is a BIOS flash, or manual voltage settings.
I tried low vdroop but it didn´t make any difference. But it´s ok, i can set the vcore manually but i was just investigating if i could get the best of both worlds with the powersavings auto vcore offers during idle

MSI 945GCM5 V2 how change cpu voltage

I have Dual-Core E2160 VRam CPU voltage 1.3.. its lowest? I dont know where in Bios can this be changed.. because iam on stock 1.8GHz and temp is still 70°C+ in idle. (but in bios its wrote 50°C)

The Alpine 11 is almost as weak as a boxed cooler. It is a most simple all aluminium cooler without any heatpipes that is limited to just 95W TDP max. According to Arctic it cools a i5-2500K 3°C better than the boxed one.
Measure temps under load and in idle with Core Temp and report back.

BIOS doesn't change CPU Voltage P55-GD65

I have a P55-GD65 with BIOS Ver 1.7
No matter what setting I put the the CPU voltage it seems to run in auto only. I have tried many combination's of settings that I have read on the forums but nothing seems to be working.
Has anybody had this problem?
Thanks,
Mark

Yes even when I have Intel C-STATE and Intel EIST disabled.
The voltage is much lower. I can't over clock because I cannot up the CPU voltage. I have the CPU multiplier at 21 and the clock at 155. If I go even up to 156 on the clock my system will blue screen.
When I put the voltage in Auto and monitor it and then put it in manual and crank it up to 1.45 and monitor it the voltage behaves as it is in auto. I have XMS 1600 memory and the Mugen B rev 2 cooler so I know that is not an issue. I might have a defective MB. I've been building PC's for years so I'm not a newbe. I've usually used Supermicro boards and this is my first MSI board. The board is very nice and if it worked it would be great. I was going to build another system with that board but am a little gun shy now.
Thanks for all your help.

CPU Voltage of 11.7V Why?

Hi,
today I looked to the command "dmidecode" to visit the cpu voltage. I saw that the voltage is on 11.7V, is that an Error? And the other thing I visited, is that the cpu clock is always on 2.400MHz, but the system utilization is very low (only few % on each thread). Why is that?
This is the output of the command:
Version: Intel(R) Core(TM) i7-3517U CPU @ 1.90GHz
Voltage: 11.7 V
External Clock: 100 MHz
Max Speed: 3800 MHz
Current Speed: 2400 MHz
I hope someone can help me.
Murmel

You should be using lm-sensors for these data. Even then, unless someone knowledgeable has verified each voltage output and mapped it to the correct motherboard sensors, you are guessing. To look at both endpoints, vcore and frequency, try i7z-git from the AUR. It reads the MSR values directly from the CPU.

[915 Series] CPU Voltage and clock multiplier

The manueal of 915G combo says(page 3-24):
Adjust CPU Voltage
The settings are used to adjust the CPU clock multiplier(ratio) and CPU core voltage....
I dont know how, and you?
Can anyone explain that to me, please.
cheers

If the value has a "v" or "X.XX", it'll be the value for setting the CPU voltage as Mutiplier settings only comes in full numeric value like 1, 2, 3, 4... 20 etc.
My guess of why it is being phrased as such is mainly to due the different settings to o/c a system may require a minor increase of the CPU Voltage to keep the whole system to run stablely.

I don't own a Neo2 anymore, although I wish I did. IMO it is THE best s939 AGP board out there. It is good to hear there is some dividers available in the BIOS now too, lol.
Anyway, if you mess with the different CPU voltage settings, you are sure to find a combo that puts it right where you want it. And I measured the vcore directly off of the board with a mm - I don't usually trust apps for that sort of thing when pushing 1.7+ volts into a 90nm or 65nm CPU.
It is also my experience that Ntune should only be used in case of emergency, if all else fails. I have had nothing but problems with that stupid program and I wouldn't touch it again with your PC if I had the choice. If you've got clockgen, A64 Info, and Core Center, you can rule the world.
