Dumb Question:What does the 4 gig patch do?

Jan Kyster · 11-30-10, 08:49 PM

Thought of making a really heavy mission with quadzillions of ships, but then it struck me! The OM Museum!
Always known as a "Not To Be Used!" option because of crash!

So loaded OM with all stuff and quite right - SH4 crashed.

Here's the Process Monitor screendump.
Note how the max. memory use do not exceed 1.65 GB! but it still crashes...

Now the LAA patched SH4 Process Monitor screendump:

Conclusion:
Reason for SH4 crashing in Museum, is because of the 2GB limitation. Using the LAA patch now allows for opening the museum.
Max. memory 2.21 GB for OM!

However, the sea is very strange.
Like high speed water flow... but of course, noone has ever seen it before...

Been running with the LAA patch for some 10 hours and have found no side effects, so I would say it's safe to use.
And if you would like to see the Museum, it's a must have!

/edit, note re. memory use.

Extra memory used for 9 to 23 ships = 1.40GB to 1.48 = 80MB
With Max memory = 1.65GB = crash, then we have 1.64GB-1.48GB = 160MB in real overhead.

Which is only twice of what required to meet 22 ships in the open ocean. No harbour, shallows, land etc.

All my installs now have the LAA patch. Imho it's a must have. Thanks for the hint, BubbleHead!

Btw. Bubble, you should change the thread title to "[Solved] What does the 4 gig Patch do?"
It does nothing but good!

Thanks for the info;

I tested the premise and can confirm that the museum is viewable with the 4Gb patch installed on Win7, 64 bits.

@Jan Kyster,

Great report!
I knew you would give us the needed facts in a
concise way.

I run SHIV 1.5 modded to TMO2 on XP Pro on x86 processor. I have 4GB memory. I tried to install patch by executing it and got error message saying it can't install 'cause it couldn't verify version of SH.exe. Huh? I installed it in C:\SHIV, not C:\Program Files\etc..etc. What am I doing wrong?

12-02-10, 06:38 PM

Did you browse to your install folder or just click and hope it would find it?

12-02-10, 07:13 PM

I browsed to C:\SHIV 1,5 which is the folder that I installed into. There is an SH.exe in that folder. I tried three other folders which also have modded versions of SHIV and got the same error, something about can't verify the version of SH.exe.

12-02-10, 07:30 PM

OK.
It was my fault.
I pointed to the 1.2 version by mistake.
Don't know why I have that .exe hanging around.

I'll rebuild and update the patch.
Thanks for catching this.

LAA patch is the same 4GbPatch? I have this in SH4; TMO with RSRDC OK, but OM, without museum. Glup!

No, it's not. But the end result should be the same. Setting the Large Address Awareness-bit.
However I prefer the "original" work since this have some more features and may handle all kinds of programs... follow links in above posts.

OM Museum - Glup??

Can open it at any time. It do take some time due to the massive amount of ships and planes, but eventually it gets there...

Impossible to open without allowing SH4 to use more RAM than it's native 2GB (=1.6GB) address limit permits... as screendumps above shows.

Fish40 · 04-20-11, 03:08 PM

There is a utility hosted here, just for the SH4exe. I also installed the LAA, and have used it for Il21946 with UP2.01, and BOBWOV with the 2.11 update and multiskin. It seems to have cured some random CTD's in both of them as well.

Charlie901 · 03-01-12, 09:33 PM

Tried to install this Patch to the SH4.exe and keep getting an Error that it can't patch due to the SH4.exe being an "Unknown" version...???

I have version 1.5 and am pointing the patch to the C:\Ubisoft\Silent Hunter 4... folder.

What could be the problem???

Jan Kyster · 03-01-12, 11:44 PM

Use this generic patcher instead... http://www.techpowerup.com/forums/sh...d.php?t=112556
