Brushed IPA around the SPI-flash

Everything you need to know is on the forums, if you plan on upgrading the CPU in your 2009 Mac Pro you will first need to flash it from a 4.1 to a 5.1 and DDR3 1333 MHz will be come available after flashing to 5.1 although you might need to purchase new ram for this. and instructions on how to do so are a search away. also if you plan on new CPU's then you will want to go hex core 6 cores and will need to delid the CPU remove the ICH from the CPU. again instructions are a search away. or you can go with the shim method if your not confident with Deliding a CPU. use shims not stamped out washers.
As for a GFX card Mojave the soon to be released OSX supports AMD cards and one which falls into the Mac Pro's available power usage is the AMD RX 580 sapphire pulse card. but that has no boot screens, if you need boot screen then the GTX680 Mac edition or a flashed GTX 680 will suit better.
As for NVMe boot drives this is still not available from apple direct, but as you can see from this tread there are some with substantial knowledge on how this is attained. Samsung AHCI drives are supported but becoming harder to find as they are no longer made, but offer similar speeds to NVMe drives using a single PCIe controller card.
Good luck with your build and welcome to the forums!
It’s risky, but I only use it to clean boards when the humidity is high enough.

To boot from a NVMe drive, you need to inject the NVMe driver into your Mac Pro firmware, I can help you with that.
If you gonna buy a NVMe drive, look at Samsung 970 EVO or Pro, if you want a cheaper/bigger drive, HP EX920 https://www.newegg.com/Product/Product.aspx?Item=N82E16820326778

GPU depends a lot on what you do. So it’s better that you wait until you started to use your Mac Pro. Maybe you will need boot screens, or hardware encoding or CUDA. So, it’s the last thing.

.Definitely want boot screen but want powerful card for Fusion 360 CAD and video editing. Whats the best value with boot screen, especially in light of the new boot rom.
Results in MAC OSX 10.13.6 using RAID0 created by MAC OSX DISKUTIL. Slot 2
With 1 NVMe I achieved the following results:
Read: 2609.7
Write: 1925.8
With 2 NVMe in RAID0 I got the following results:
Read: 4301.3
Write: 3305.2
With 3 NVMe in RAID0 I got the following results:
Read: 4703.8
Write: 3846.1
With 4 NVMe in RAID0 I got the following results:
Read: 4793.5
Write: 3646.0
Okay so basically the best performance is with 2 blades. I mean thats highest difference from all blades and I guess the best option based on money versus performance.
Do you think the Amfeltec Squid with 4 blades in another slot would increase the results significantly? I am currently thinking of buying a card for 2-4 blades and bring them together on a software Raid with SoftRAID. With your results I better save some money and only gor for a 2 blade option...

As you can see with Amfeltec PCIe 3.0 and PCIe 2.0 tests ... PCIe 3.0 present the same results for 2, 3 and 4 blades ..
Amfeltec told me for the Mac Pro 4.1 Gen2 would be enough, no need for the Gen3 Card. On Gen2 the performance increased a lot with 3, 4 blades in that test!
Now I am again confused hahaha.
I am using 10.13 for now and depending on your budget one the most powerful gfx card is the NVIDIA GTX TITAN X. I got one from eBay for 550EUR with EFI flash. If money doesn't matter, go get a TITAN XP Pascal with EFI flash.
I still have a boot screen on my card and it is very powerful. But not sure if it fully supports 10.14 with boot screen etc.
The best choice IMO.I guess the budget choice would be the sapphire Radeon 580 8gb?
Now its a good time to think about putting in some kind of socket with all the Firmware mods you do ? Maybe something with just short wires. Makes live less riskyI forgot to find one little but crucial tool, the Pace micro-tips for my solder/desolder station. It's not something I use frequently, so maybe it's hidden in a box somewhere.
I found my Hakko ones, so tomorrow morning I'm gonna change stations and then I'll solder the SPI flash.
Another thing, don't buy cheap no-clean flux, at best you gonna get dizzy and can't desolder anything…

I purchased server ram with small heat sinks and swapped the large heat sinks of obsolete 512MB sticks. Didnt cared about the little speed loss from 800 to 666 Mhz. Thats an affordable way to get more Ram to the 3.1.
Was an easy swap but I had a box of 512MB Sticks, not all heat sinks fit on every server Ram.
Cleaning the old solder on the pads:

SST25VF032B initial solder on the pads, no-clean flux I have only create a mess, don’t work.

It’s not perfect by a mile and I’m not satisfied with the result, but will do nicely.
VDD, pin 8, it’s difficult to solder, heat sink. Had to up the heat to 450ºC to get it done.

The next one I'll have to do, I'll use a real solder flux to remove/clean pads and solder paste/hot air to reinstall the SPI flash memory.
I can do a lot better than that, but without flux, I just couldn't. Did it fast, without microscope and without my preferred solder iron/solder tips.Looks a good job to me, that is not easy to do, main thing is you will now have your Mac Pro back to its former glory. well done

That poor solder job will haunt me no more.
Got the Pace with the chisel tip and did a drag soldering, now I’m in peace with that.
You will need a microscope to find the solder job now.

One thing, that excess solder will make a lot easier to remove the SPI flash if I ever want to install that black Aussie SOIC8W socket.
