Q: RAM and SSD PC upgrade for Photoshop stacking

Post by jac B »

Hi,

I use a PC with:
-CPU: intel core i7 7800X [clock freq. 3.5GHz/4GHz, 6 cores, socket 2066];
-RAM: Corsair Vengeance LPX DDR4 DIMM 16 GB - 2 x 8 GB 2666MHz [2.666MT/s];
-Solid state drive: Samsung 970 EVO 250GB NVMe M.2 [M.2 80mm, 3d v-nand (TLC), PCI-e 3.0 x4, 3.400MB/s read (seq), 1.500 write (seq)];

The memory is fully used and the SSD capacity is too small for Photoshop ‘stacking’ 70 RAW photos (91.300Kb per photo). The processor nor a graphics card don’t seem to be a bottleneck. Or I’m wrong?
(how) Do you know if a Samsung 970 EVO Plus 1TB and a Corsair Vennegeance LPX 32GB DDR4 3600MHz are sufficient for Photoshop ‘stacking’ 300 RAW photos?

Indented upgrade components:
-RAM: Corsair Vengeance LPX DDR4 DIMM 32 GB - 2 x 16 GB 3600MHz [3.600MT/s];
-SSD: Samsung 970 EVO Plus 1TB [M.2 80mm, 3d v-nand (TLC), PCI-e 3.0 x4, 3.500MB/s read (seq), 3.300 write (seq)];

FYI: I'm using the latest (non subscription, free trial) Photoshop (Ps), Lightroom (Lr) and Lightroom Classic (LrC) versions.

Regards,
Jac B

Hi Jac,
Do you have any problem with the performance of the stacking of the 300 shots a 10MB ?
BTW, PS is not the best software for the stacking!

I could't and didn't try 'stacking' 300 RAW photos, because the PC already failed Photoshop ‘stacking’ 70 RAW photos (91.300Kb per photo). Thats why I ask for upgrade help. Do you have (an) upgrade suggestion(s)?

Can You explain why, because I viewed a video (https://www.makro-treff.de/de/article/f ... ht-gemacht) where is told that PS stacks the most clean and only after PS doesn't give the wished result, try Zerene Stacker or Helicon Focus.

Hi Jac,
As far as I can see you don’t have any problem with your PC but with PS :-)
PS is really good for the retouching but not for the stacking.
You can download and test Zerene Stacker (or Helicon Focus) and check your PC.
BTW, I have already calculated with Zerene stacks based on more than 1500 single shots (TIFF – files a 184 MB )

Thanks for clarifying. That is good news.

Thanks. When you say Ps, do you mean Lr and LrC as well or not good for pre- and post- processing?

That are a lot of files and MB's.
Your TIFF example raises another question, about the photo pre-, stack- and post- processing workflow, namely: (how) is it possible to: 1) pre proces in (Nikon) RAW, 2) convert RAW to Zerene-format, 3) Stack processing, 4) convert Zerene-format to RAW, 5) post proces in RAW? Which tool(s) are best use for the conversion and what will be the resulting RAW-format?

Jac

Hi Jac,

I don’t recommend anything but I only can describe my workflow:
- taking of the photographs in RAW
- developing and conversion of the RAW-files into the TIFF 16 bit by LR
- calculation of the stack by Zerene
- final retouching by PS / Topaz
- resizing for the WEB by WebSharpener

BTW, your PC is good enough for the stacks based on 300 picts :-)
But for the future you will probably need a second SSD :-(

Why, a second SSD for processing or for final storage?

Hi Jac,
Both :-), because you have only a small 250GB SSD (probably with Windows).

Thanks for helping. Yes, indeed Windows.

You have a 2066-system with i7-7800x and that system uses 4 channels of DDR4, instead of "normal" 2 channels. You do have 8 ram slots on the motherboard right?
The best thing would be to add 2 more identical DDR modules to the ones you already have, or buy 4 new modules if you want faster memory speed. The official ram speed support for the 2066 is DDR4 2666/2400 (only 2400 for the Intel 7800x cpu) so DDR4-3600 is not officially supported, but I have seen people using ram speeds of 3000 and over at least. You will need to go into the bios and select using XMP-profile for the ram to run at its full speed.

Hi Bakwetu,

Thanks for your explanation, suggestion.

Where in Windows 10 can I check (not change) with which DDR4 ram speed the i7-7800X (2066 socket) is actually running?

Which intel motherboards/systems/sockets/processors officially support DDR4-3600?

Jac

In my experience from other process intensive tasks, RAM speed (and matching RAM modules) is not that critical.
It‘s nice to have and you might gain a few percent speed increase, but it‘s not worth spending a lot of money on.

Having enough RAM can be really important and speed up things significantly (as can having a fast SSD and or course CPU), so this is where I would invest my money.

I never really tested speed on stacking software though, so others here will have more insight on that.
