A75MA-G55: Lab Burst Mode temp sensor bug

Me and a friend were on a quest to find the best BLK frequency on stock voltage and finally arrived on 153MHz to be the max possible on stock voltage.
We went some benchmarking on 7-zip, GTA4 and wPrime without problems, only we can't measure the cpu core temperature because of that no software can't give us an honest result.
Then our heads came up with an idea, howbout 2hours Prime95 then quick reboot and check temps from Bios.
2 hours later quick reboot, enter bios and there we almost passed out... CPU temperature: 128 degrees Celsius but case temp on 27degrees C.
We left the system off for 3 hours then checked again from a cold boot, 128 degrees C again! then we changed to default settings and there we go 25 degrees C, we switched back to LabBurstMode and temperature showed us again 128 degrees C.
Maybe this was a planned Helloween trick from the MSI team But this have to be looked at.
System:
2x A8-3850 chips
2x 1866MHz Kingston 4GB
2x 1600MHz OCZ Gold 2GB
MSI A75MA-G55
Asrock A75Pro4-M
500GB WD Black
2x 500GB WD Green
Corsair TX650

I checked the changelogs for the standard BIOS release series of the A75MA-G55. There are two references to "Lab Burst Mode".
The first appears in the changelog for the E7696AMS.138 [v1.3b8] release:
- Change setup item "Enhanced Spread Spectrum" to "Lab Burst Mode".
The second reference appears in the changelog for the E7696AMS.139 [v1.3b9] release:
- Fixed Lab Burst Mode always enable when OC more than 133Mhz successful then load default.
That tells us three things:
1) The option should be available be available in the E7696AMS.130 final release under the name "Lab Burst Mode" and as "Enhanced Spread Spectrum" in all final releases before that.
2) The "old name" for that option suggests that it has to do with "clock modulation" (because that is what Spread Spectrum generally does).
3) Spread Spectrum probably may need to be enabled first in order to get access to the "Lab Burst Mode"/"Enhanced Spread Spectrum" option.

BF3 w/ A75MA-G55 OCed

I have my llano(16-3650) clocked to 140+ bus clock with lab burse mode enabled, it runs everything great and passes all benchmark tests except for BF3. With lab burst mode enabled and base clock above 133, BF3 has weird problems(you dont run as fast and people warp all over in multiplayer. Once base clock is put under 133 it runs great again(yes i tested on the same server). Anyone else had this problem and have any suggestions/solutions? I hate to put it back to near stock speed but thats the only way it will run the game right currently.

I tried A8-3850 on 150MHz BLK and play Dead Island, no problems(In fact it was smoother than ever!). League of Legends... everything went in slow-motion and speeds up randomly similar to a overly spec'd HD-TV. I think it's depending on game when overclocking a bit too much. (But damn 150MHz on 1.376v is pretty damn impressive, GJ MSI engineering team!)
Ya, it works fine for some games/apps(SC2 works great) but with BF3 it does weird stuff similar to what you are describing. If I put it at stock clock it runs bf3 fine.

Yet another bug in Photoshop CS3: Lab Colour Mode

Using Photoshop CS3 Standard (english) on Windows XP SP2, I cannot switch to Lab colour mode. Or rather, I can, but the image will turn completely black. In the channels palette in Lab mode, there are four channels: L, a, b, and Lab. The three single channels obviously contain the correct data, and I can select each one and the display will show the correct greyscale representations of the L channel, the a channel, and the b channel. But it won't show the colour image of all channels combined, i. e. the Lab image; this will appear simply black instead.
Fortunately, I still have Photoshop CS2 installed. So due to this and numerous other bugs (particularly the §@#!& printing) I am using Bridge 2.1 and ACR 4.1 but not Photoshop CS3. This application is just too buggy to get serious work done :(
-- Olaf

The exact same thing happened to me just 2 days ago. It was the first time I had ever tried LAB, in any version of PS, and all I got was the black box. I switched to my earlier version (PS7 in this case) and tried it, thinking that maybe my computer wouldn't support it for some reason, since it's several years old. PS7 displayed LAB just fine... I went back to CS3 (I had closed it down completely) and when it restarted - it LAB worked correctly, BUT all my preferences had been reset to default! So, I agree with the previous poster who commented that it may be a preferences thing. You should also check the color management settings in your earlier version & make sure the CS3 has the same settings. I have no idea if that made a difference or not, but I did notice that my CS3 didn't have the same color settings as PS7 did. Try resetting preferences to default, shutting down CS3 and restarting, and then check to see if CS3 will display LAB correctly.

Problems new build A75MA-G55

Hi all,
I put together a new system last weekend, which ran for about 2 days, and then it basically stoppedworking properly. The hardware components are:
MSI A75MA-G55 with an AMD A8-3850
2 x G.Skill Ripjaws-X 8 GB, PC3-12800, 1600 MHz, 9, Non-ECC
SSD Kingston HyperX 120 GB, S-ATA III / 600
Seasonic X-400 Fanless 400 Watt
The whole thing is in a Fractal Design Define Mini box, and the OS is Ubuntu 11.10 x64 version. When it was running, it suddenly froze; after I restarted it, it did not boot and crashes with segfaults and kernel panics (both "normal" Ubuntu and the safe-mode). Once in a while it actually boots (both normal and safe mode) but is not stable and freezes after a few minutes. I have tried the following things, with no result:
- ran memcheck for 24 hours; no errors
- used a different harddisk w/ Ubuntu; no boot
- used new Win7 install and Ubuntu Live USB sticks; no boot
- updated bios to v1.3; this went without errors but still no boot (and re-tried the above again as well)
What I will try in addition is to use a different PSU to ensure that is not the problem.
What I would like to know is, if there is a way to test/validate the motherboard and/or APU without an OS (and another board) and if anyone has any idea what the cause of this can be. Any help/input/ideas is much appreciated!
Thansk in advance,
Joost

SafeMode is not a bad test for possible memory problems, but it doesn't seem to run all that well there either?
Ubuntu is not my department. I was considering a mal-functioning memory, too. What other kind did you try with?
You can also try without the hard disk altogether, and see if things keep running well for an hour or so. Try having BIOS hardware monitor visible during that time, to see if temp. keeps climbing. That is usually evidence processor isn't very fond of your memory.
Use a single stick. Set memory speed down. Make sure memory gets the volts it wants, try 1,65 volts for example.

No need to clutter up the beta thread with final releases when it is readily available at the MSI Global Website for the mainboard; http://eu.msi.com/product/mb/A75MA-G55.html#/?div=BIOS
Don't use Live Update. For flashing, use the forum's USB Flashing Tool found here, along with instructions how to use it; https://forum-en.msi.com/index.php?topic=108079.0
Like I said earlier, I can't download the 1.3, it says my bios is the latest. And if MSI could be sweet and put a download link instead of pointing to Live Update.

Difficulty with CJC using on board temp sensor - SCB-68

I am trying to do Cold Junction Compensation using the built in temperature sensor on my SCB-68 connector block. I am using the 6224 M Series PCI DAQ card. I am having two problems:
1. I found a procedure on this forum for reading the temperature sensor which, in my case, is at channel 16. So, I have my connector block switches set so the Temp sensor is enabled, and I am in differential mode. I created a global channel called "TempSensor" and set it to channel 16. I applied a scaling of m = 180 and b = 32 to get farenheit. When I do this, and I test the channel, it reads a temperature of 75 degrees. This seems a little hot for my office, which is probably more like 68 degrees. Any idea what might be wrong? I don't have to connect anything to the board to read the temp sensor, do I?
2. I've connected a type T thermocouple to channels 20 and 28 (differential). For CJC, I can set it manually by estimating the temperature in my office as 68 degrees and puting that value in the CJC Source Constant field. When I do this, the TC seems to work great. It reads around 68 degrees in my office, and more like 85 if I squeeze it between my hands. So, now I want to use the "TempSensor" global channel to do my cold junction compensation automatically. When I select my CJC Source as "Channel" and enter "TempSensor," I run the test and get temperatures of 176 degees F. What am I doing wrong?
Thanks for any help!
Kevin

Dear Kevin,
There is a really easy way to test your thermocouple using the Built-In CJC of the SCB-68. The only time I set up a global channel for the CJC is to make sure that it is working correctly. The CJC temp does not indicate the temperature of your office, it indicates the temperature of the SCB-68 board. My CJC value is 2 degrees warmer than the room temperature. 75 degrees is a reasonable temperature to get.
After you check the CJC to make sure that it is working, you can set up the task in the Measurement and Automation Explorer (MAX). Expand Devices and Interfaces>>NI-DAQmx Devices. Right click on your device and select Properties. Click on the Accessory Tab and add the SCB-68 to the second connector and click Configure. Check the box for Reference Temperature Enabled. Click the two OKs to save your changes. Then create your thermocouple task normally and select your CJC source as Built-In.
Now, it will detect temperature changes that you add. Please let me know if you have any questions. Have a great day!
Sincerely,
Marni S.

Conditional actions in Photoshop can't test for Lab color mode.

I’m posting here because the feature request/bug report form isn’t currently working for Photoshop.
I wanted to create an action to determine if the color mode of an image is Lab, and if so, convert it to RGB. But there’s no conditional action test for Lab color mode. The list of conditions that can be tested includes RGB, grayscale, and a couple of other color modes, but not Lab, Does anyone know of a workaround? Can I get it done with scripting?
It would be a big help if the next update of Photoshop CC could include a conditional action test for Lab color mode.

This for example would convert an active Lab image to sRGB:
if (app.documents.length > 0) {
if (app.activeDocument.mode == DocumentMode.LAB) {
app.activeDocument.convertProfile ("sRGB IEC61966-2.1", Intent.RELATIVECOLORIMETRIC, true, true);

HD7950 temp sensor always zero + auto fan always 100%

After installing new card and latest CCC software and drivers as soon as windows starts, the card fan goes to 100% even at idle. In Performance section of CCC GPU temp reads 0c at all times even under load.
Tried uninstall CCC, remove card, re-install card and then CCC, no dice... same problem. I can manually adjust the fan speed in CCC but it's a PITA and shouldn't be necessary.
Do I have a faulty temp sensor perhaps?
Thanks....

Quote from: flobelix on 26-November-12, 13:46:47
Obviously either driver isn't correctly installed or it's indeed a sensor misreading caused by a defect.
Remove current driver in safe mode using>>Driver Fusion<<. Reboot and install latest MSI driver:
Thanks for the suggestion. Gave it a whirl but still the same deal. Temp 0c - Power 0% - Activity 0% - Fan 100% from the moment Win7 starts no matter what the card's doing.
Only thing I didn't follow to a T from syour suggestion is that the free version of Driver Fusion said it required upgrading to Pro to remove all driver items even in Safe Mode.

GPU 0 Die Temp Sensor ERROR on a MacBook Pro. Can anybody help?

Hello.
My wife has a 15-inch, 2.4GHz MacBook Pro model 3.1 laptop.
All of sudden the screen started to flicker, and after that, it could no longer be booted. Applelogo visible but the timewheel stops and nothing happens.
I managed to get hold of a copy of ASD (Apple Service Diagnostic) for her computer, and I found out what was wrong:
There is a test called "Temp Sensor - GPU 0 Die Temp" that fails. I get the following message:
"Temp sensor GPU 0 Die Temp test 1 - Sensor Reads Within Operating Range
- Check to ensure that sensor reads within operating range.
ERROR - Unable to read sensor
- TEST FAILED -
Temp sensor GPU 0 Die Temp test 8 - Sensor Noise Test
- Checks that sensor Noise is within spec.
ERROR - Unable to read sensor
- TEST FAILED -"
If I look in the "Hardware Profile" under "sensor" I find the following:
"Sensor
type:            Temperature
location:            TG0D
low-limit:            15
high-limit:        85
reading:            1.0
description:        GPU 0 Heatsink Temp
noise-tolerance:    1.0"
The thing is that the problem seems to be intermittent. It comes and goes. All of a sudden the test passes and I can boot the computer. Some days the computer can work for a whole day, so it doesn´t seem to be related to temperature.
What do you guys and girls think? Is this fixable by myself? Does anybody know where this sensor is located? Maybe it´s just a bad connection, since it´s intermittent?
I feel I have come a little bit on the way to be able to solve this issue, and it would feel like a failure to be forced to leave the computer at an Apple Service Center, if it´s even worth it to do that. There is a risk that the computer is not worth a repair.
Could someone please chime in here for a clever advice?
Thanks.
Bo Reimer.

Welcome Bo!
It may be related to a known problem with MBPs 3,1 and 4,1. Some had a bad Nvidea Geforce 8600M GT video chipset that could fail under high heat cpnditions. There is an Apple Repair Extension Program (REP) that will fix the defect at no charge for up to four years from date of purchase:
http://support.apple.com/kb/TS2377
You'll need to have an Apple retail store or an authorized service provider check the computer with a special test gadget for positive ID of the problem to qualify. If it does, you get a new logic board. Reported turnaround for the fix is from same day to three days.
If their test does not turn up the Nvideo curse, you still have an affordable repair option if you live in North America (It would he helpful if you fill in the "Geographic Information" field in your profile--at this point I'm having to assume you're in N. America)).
The option is a depot repair. Apple sends your computer to their central refurbishment facility and bascially fixes anything outside of cosmetic damage for a flat fee of about US$315--much cheaper that a new computer. Taxes and shipping may apply.
People who have used this option are reporting excellent results and a turnaround of about one business week.

Problem with Bios 2.0 MSI A75MA-G55

hello, I need help ....
A few days ago I did the update the BIOS of my MSI-A75MA-G55, which is 2.0 and he has presented problems. It has a processor (AMD A-8 3870K) before trouble could overclock to 4.0GHz, but now it goes from 3.6ghz: (... By increasing to over 3.6ghz pc does not start and I have to clear the CMOS for reuse ... the second problem is with the GPU hd6550D now I can not run any game at medium quality such as "far Cry 3" or "Bioshock Infinite" and before if I could .... the previous BIOS version was the V13 or 1.3 which everything worked.
The characteristics of my pc are:
- MSI Motherboard-A75MA-G55 (MS-7696)
- 3870K Processor A-8
- 2x 4GB Corsair Vengeance DDR3-1333 (667MHz)
- Hard Drive WD 750GB 64MB Cache
- Thermaltake CLP0575 Frio OCK
Thank you in advance ...!
Sorry do not know much English ...!
Note: I did a BIOS flash, with the tool provided here, to downgrade the BIOS version and I could not because at the end and restart the PC had always the same version.

As the problem is only bios related from your report tell MSI about it so the issue can be fixed: >>How to contact MSI.<<

In iOS 7 is there a way to turn off that new camera burst mode?

I like the old camera ability to keep your finger on the shutter and release to take a photo. It helps avoid camera blur with certain close shots you are trying to frame, and was one of my favorite "hints on using your camera" for the iPhone.
But with iOS 7 this has turned into burst mode, which is driving me crazy.
Is there a way of turning off burst mode for the shutter button and having it work like it did before?
Thanks,
doug

Thanks, Doug. I'm a little disappointed to discover so few of us who miss what I consider one of the iPhone camera's cleverest refinements. Being able to hold one's finger on the shutter and release to take the photo is something I did by habit, and now sorely miss.
Most troubling to me is that the change represents a shift to favoring an entirely new way of taking photographs — a style I'd conservatively call, "by the seat of your pants". That's never the way I've taken photographs.
Like Nadnerb19, I'm hoping Apple reconsiders its priorities, and gives us the option to make a choice between machine gun style photography and the steadier, more 'focused' approach afforded by previous versions of iOS.
