I'm going to do this anyway but....
 

So - when I load some saved games in OM they crash the game - it just freezes up on the loading screen. I've noticed it's more prevalent if there's a convoy in the vicinity and I'm wondering if my two gigs of RAM are up to the job. Anyway I'm off to slot in some more - One thing it oughtn't to do is make anything worse, but can I expect this to fix the problem?

I'm assuming this isn't a general issue with OM because if it was it would be all over these forums

Four gigs should help, also get the 4 gig patch for SH 4 from the downloads area. I had the same problem with OM also, even with plenty of RAM, just never saved with a convoy near.Convoys are much larger on Allied side. Saving near IJN convoys, much smaller compared to those in OM creates problems as well.

This really is a mystery.
I have been lucky so far (knock on wood).

HP Pavillion (found tossed in trash due to burnt graphics card), with:
1.8 Ghz Core 2 Duo;
2 Gb RAM
Nvidia GeForce GT 440 w/1Gb memory (bought as replacement)
500 Gb HDD
Win 7 Ultimate x86 (32 bit)

Never (so far) a corrupted save, not even with enemy convoys in radar.
However I never saved under water due to advice from experienced skippers on this forum.

SH3 and SH4 in high settings for the most part.
SH4 w/1.5 version (UBM).
Only a few minor mods. I'll consider popular mega mods after I finish my first career.

I regularly run a couple of system clean-up and tune-up programs, and I'm also careful about the start-up list.

It only happens with OM - I had OMEGU loaded, and I removed that and went to OMPLOT, which seemed to help. It hasn't crashed mid-game yet, but just had the first bite out of a big convoy, surfaced about 10 klicks away and saved, ready for the next installment - went to load and it hung up on the loading screen - I currently have 2 gigs installed so this should take me up to 6 - I just grabbed the Large address aware patch - I'm assuming that's what I need - Let's see what happens......

Bubblehead1980,
I don't mean to side track this thread, but could you or anyone tell me exactly what "the 4 gig patch for SH 4" does?

Thanks...

it allows for more then the 3gb set limit of ram to be used

What Webster said. Does help with CTD issues, I rarely get CTD's since installed it.

I must be lucky as I never had a crash in OM unless OMEGU is installed too.(Which sucks as I really like the stuff it adds.)

Well, if this does the trick, I'll probably reload it

Does that include XP?

Yeah - As I understand it, when the game was written it wasn't thought likely that the machines it would be played on would have more than 2, or 3 gigs of RAM, so the game only looks for that amount - What the Large address aware utility does, is it tells the game that there's more memory for the taking. It's certainly improved the frame rate - Now to see if I can load my saved position....

Thank you again Mr. in_vino_vomitus.
You have been very helpful once again.
I have 4 mgs in my XP, maybe I should give this a try.

I would say so - I don't know if the game uses 2 or 3 gigs as standard, but if you have 4 then some of that is definitely going unused

While running the allied side of the game I never had this issue. About a month after I started playing the axis side only I began to run into this bug. Now it will almost never load a saved game unless that happens to be on where the game saved it in port after a patrol.

I'm going to test the theory about convoys but I have saved it before on the allied side with huge convoys and task force's and never had an issue.

I run the game with 8 gigs of ram

Well - adding an extra 4 gigs hasn't cured the save problem, but it does seem to be running smoother. I tried to reload a couple of saved positions - all with a convoy in the vicinity - the game just crashed, it didn't hang up - The save that finally loaded was one after the first pass at the convoy - I'd got a bit too much separation, I think, and I suspect it despawned - either way, I couldn't regain contact.
