2009 Mac Pro Processor Change – how to resolve errors?

I have a Mac Pro “Eight Core” 2.26 (2009/Nehalem) that I was running with dual X5690 (3.46GHz/6-core/12MB/130W) processors for the last couple years (yes, I’ve got the 2010 firmware hack on it). Been running fantastic, but I needed to do swap some hardware around and so ended up needing to take these processors out and put some older processors (that were from another actual 2010 Mac Pro; 2.66 GHz 6 Core Xeon X5650 x2).

After the transplant was completed I fired it up and immediately got a light on the right side of CPUA:


I held the power button in and immediately turned it off. This light then lit (“OVTMP CPUA”):

I figured something must be up with the heatsink as it seemed as though the screws for the 2009 heatsinks ratcheted down tightly and immediately instead of having some give that would indicate that it was in contact with the CPU (lidded CPU btw). Made me figure that perhaps the heatsink was not pressing down the CPUA processor enough. I also recalled that the previous processor that was in here may have been SLIGHTLY taller.

I then took the heatsink back off and put about .5 to .75 mm of copper cut to size for the Xeon lid and used thermal paste again to make up for this possible spacing issue. I repeated this for CPUB. The heatsink seemed to ratchet down better this time as I could feel some pressure being applied and the torque didn’t stop immediately as before and thus i could torque it down a bit.

After doing this, I unfortunately found that the same error lights were emitted – no change.

I also went ahead got some additional feedback from the DIAG LED button:

I’m not really sure what to do at this point. Should I add thicker copper to make the heatsinks apply greater pressure to these Xeon processors?

I believe Intel has pretty good heat protection for these processors, so I don’t believe the processor would be “burned out” at this point, right?

Further, would resetting the motherboard by removing the battery and / or pressing the reset button beside the battery (above the 1st PCIe slot / behind the GPU) help at all?

Any other ideas aside from buying a new processor?

Is there a simple image processor that can reduce image color depth (convert 24-bit RGB to 2, 4 or 8-bit indexed color)?

I have a need for a quick/easy image processing application under Ubuntu 18.04 that will allow me to view, crop, scale down and reduce color depth/color mode (number of color bits per pixel) – with and without dithering – of 24-bit JPG input images and export them as PNG. I’d like the option of reducing to 4, 16 or 256 colors (2, 4 or 8 bits per pixel).

GIMP has these capabilities, but I’m looking for something less bulky.

In Windows (and OS/2 before that!), I was a longtime user of PMView, a speedy viewer and processor. I can continue to use PMView through WINE (there is also an IrfanView app that works similarly through WINE), but I would prefer a Linux app.

I have tried a number of applications. I like the simplicity, cropping, resizing and even the color manipulations of gThumb. But gThumb does not allow me to save a PNG at less than 24-bit. Same problem with Shotwell and Mirage. I’ve had no luck getting usable results with Pinta.

Ubuntu 18.04.2 LTS support for Intel Core M Processor

I never installed a Ubuntu Desktop on Intel Core M processor before and not even on current laptop. I am trying out Ubuntu 18.04 LTS. I am facing non-smooth animations of app drawer and stuttering of UI. I came from windows 7 and laptop was working super fast with aero enabled.

Wayland vs Xorg & Lightdm vs gdm3
I dig a little bit and found that there can be issues with wayland/xorg or lightdm/gdm3 configurations. I read in a thread that wayland doesnot support old driver hence, switching back to xorg would fix the issue.
Another article point out to use open source drivers in wayland configuration because vendor drivers does not support wayland as it is pre-mature right now.

System Monitor
In anther thread it was suggested to remove system monitor as It was causing stuttering. I checked my cpu usage and it was 100% for 1 core. So, I removed it.

Remove xorg/ubuntu-desktop – dist-upgrade – Re-install xorg/ubuntu-desktop
I tried fixes like as mentioned here:
1- remove xorg
2- dist-upgrade
3- install ubuntu-desktop

and disabled the wayland
1- disabled wayland in gdm3 custom.conf

Currently, I am running on xorg configuration and I am still feeling that experience is bit laggy. I am suspecting that it might be issue with Core M processor or I need to install the correct drivers.

I need community input on this as to have some pointers to move forward with experiments.

Processor Power Management

I am using a AMD FX(tm)-9590 Eight-Core Processor × 8 on Ubuntu 16.04. I’ve had freezing issues come up on Windows 10 before, these were easily solved by limiting the maximum processor state to 99% rather than 100%. I need to be able to do this on my Ubuntu machine now as well because the freezing issues are occurring when doing installations.

Anyone aware of how to change this settings, as I was unable to find specifics that were permanent changes for AMD and Ubuntu. An example of the windows fix can be found here. Thanks!

Smart One Page Checkout Breaks Credit Card Processor

I’m using AheadWorks Smart One Page Checkout for Magento 2 and for some reason it completely breaks my authorize.net credit card processing.

I receive this error in the payment.log

'response' => '{"transactionResponse":{"SupplementalDataQualificationIndicator":0},"messages":{"resultCode":"Error","message":[{"code":"E00076","text":"dataDescriptor contains invalid value."},{"code":"E00076","text":"dataValue contains invalid value."}]}}',   

That’s an authorize.net error code, but the only detail they give on their error code lists is that an invalid value was given. The credit card section also has a display error that may or may not be related to the error code.

Here is a screenshot with the display error marked with an arrow.

enter image description here

I cannot tell whether this display error is causing the invalid submission or not. Authorize.net credit card processing works perfectly fine the second I disable One Page checkout, and the error occurs even on a brand new clean Magento 2.3.1 installation.

I’ve tried all I can think of and am looking for any ideas on potential solutions.

Thanks in advance.

How does the memory of a 64bit and 32bit processor work

In this article, the author states that a 64bit processor can theoretically reference 2^64 bytes of memory. What does he mean by this statement, or rather the word, reference?

Also, I visualize the entire RAM to be divided into little memory cells, each having an n-bit binary number that represents a given instruction or value that is needed for running any program in the computer. Is this visualization right?

If it is, then for a 64bit processor, what would be the number of memory cells in the RAM?

Will replacing 4 GB DDR3 ram (2GB+2GB) with 10 GB DDR3 ram (8GB+2GB) work with Intel i3 processor?

I have system with Intel i3 processor, 4 GB DDR3 ram (2GB+2GB). I am thinking to expand ram with buying 8GB DDR3 ram. Will Intel i3 processor work with configuration of 10 GB DDR3 ram (8GB+2GB)?

What factors or configurations related to RAM or motherboard should I check with before configuring system with 10 GB DDR3 ram (8GB+2GB)?

Seeking an International Payment Processor / $25,000 monthly

Hi, so i have a unique service that processes about $ 25,000 in payments a month. US payment processors don't seem interested and we're trying to find something better than our current processor in Ghana. Yes Africa Ghana where half our payments fail probably because US banks see Africa as a red flag.

It's not illegal in any way, we have very low charge backs (less than 1%), and surprisingly PayPal works/accepts our platform. If anyone here thinks they have something that will accept an…
