Multiple ram sticks

[monkeygoat 0]

I recently upgraded from 256MB of DDR Ram to 768, by purchasing a second stick of 512MB. The problem is if I have both installed at the same time I'll get messed up textures, static sound and ctds.

With only 256 or 512 installed the game runs ok. Does ofp have some kind of problem with 2 sticks of ram??

Thx in advance for any help. (hinthint)

OFP won't care, but your system might. Some systems require matched SIMMs/DIMMs to be installed. If your system is otherwise stable, simply changing the AGP Aperture size may resolve the problem.

Heh, Once I tryed to see if I could mix OEM brand 64meg stick with HP 128 meg stick of pc100. When I ran a program that used the ram, some windows file got destroyed and I had to reformat.

Mister Frag they're both dimm. (sorry if I just got the wrong end of the stick, but i'm pretty clueless).

How would I change the aperture size?

Nevermind, got off my arse and found out how to do it. Gonna try it now.

You need to go to your Bios setup. Play with the diff. aperture size 32-64-128-256. Remember less aperture = system more stable

Stupid ram, aperture fiddling didn't work.

I don't understand why there is a conflict though, the ram is exactly the same type just different sizes.

Many motherboards can get flaky with unmatched modules of memory. For instance my gaming computer is a K7VZA using a VIA VT8363/VT8363A and VT82C686A/VT82C686B chipsets, which gets unhappy unless the PC100/133 modules are installed in same size pairs or triples.

I've had this problem too. I bought a 256 stick to complement the 256 I've already got and most programs ran fine but OFP would just crash straightaway.

Anyone have any other tips?

There is no simple answer to this question, it is very system-dependent.

As stated before, some systems will accept dissimilar memory modules, and others won't. Some systems will also not allow all banks to be populated with RAM, which is ludicrous -- why have the banks if you can't use them? Another possibility for causing problems are bad memory timing parameters (CAS settings), overclocking, or simply bad RAM.

I think my Asus MB manual recommends using pieces of ram that are identical in size and brand. They list a bunch of 'certified' modules for the chipset. I happily mix a stick of Nanya and Hynix of different ratings.

I suggest you download a program called DocMemory, and perhaps one called MemChecker (though I had a couple of non-errors reported once with that one), and thoroughly test your ram. If they dont work together flawlessly and consistently, then dont mix them.

I also suggest you check the model numbers on the chips, look them up at the manufactures web site and get their ratings. Dont run them beyond their ratings and expect stability. You may be able to run both at the lower rating of the two.

mmmm, dim sims!

Just wanna let you know that I had problems with my additional RAM stick as well.

Problem was solved by setting the memory timings in the BIOS to the lowest possible value.

Try this; it might prove to be the solution for you...
