Optimal RAM Setting for 4GB Multiprocessing under WinXP32
hey there folks,
searching through the forum I can see there’s already lots of discussion for optimal settings for multiprocessing for AE. However I couldn’t see one that addresses my scenario.
my system:
Intel Quad Core 2.4Ghz (Q6600)
4GB DDR2 RAM
P5Q-E Mobo
Consumer Nvidia Graphics board (however I’ve disabled OpenGL rendering as this conflicts with AE multiprocessing according to what I’ve read)
if you really have to know it’s a eVGA 9500 GT 512MBI’m broke, it was the best my ailing credit card could handle…
My memory usage settings are set to 120% (Max Usage) and 60% (RAM Cache)
OS Windows XP professional with the /3GB Switch turned on. AE sees 3GB as it boots, Windows itself reports 3.25GB if you click on it’s properties (My Computer > Properties tab)
I’ve yet to manage to get a multiprocessor preview to actually run/playback, I get a ‘ping’ error sound, the preview starts to churn slowly (though I’m testing this on a heavy duty hd comp).
Soon I begin to think this sucks so I hit the RAM Preview button again to just watch it play back, it keeps preview rendering and I see the info box report that it’s initialising background processes.
Yes.
After the preview has started rendering, not before.
Once it finally comes to a halt, I get the unable to render multiple frames simultaneously message in the info box, and my RAM preview doesn’t play.
I’ve tried changing the RAM cache (as low as 30%, and as high as 80%) to try and either restrict the number of cores it’s trying to use, or to make more RAM available to the cores. (it will only use either 1 more core, or 2 max).
I get identical results every time.
Firstly has anyone got a suggestion for an optimal configuration? I could turn off MP but really what’s the point of the multicore cpu if I can’t kick some ass?
Secondly, in my thirst for wanton power on a budget, I bought a quad core, would I have been better off with a faster GHz dual core CPU if 32bit Windows XP can’t make enough RAM available to the cores due to it’s 32bit architecture and 4GB physical address limit?
I wish I could afford a Mac.
any help greatly appreciated, I shall bear your children and carve your effigy into mountains etc.

There are no optimal settings for Ram usage,
it all depends on what you want; longer previews, more cache …
Working in 2.5D actually benefits from Open-GL a lot !
In you case, working with HD, you would need more Ram…
so start saving 😉
and more Ram requires XP64 or Vista64.
XP32 cuts out 750MB Ram and uses some remaining memory for hardware-mapping.not the answer you wanted heh 🙁
some solutions;
– buy Nucleo Pro (uses memory far more efficient than Multi-Proc in AE)
– buy extra Ram + XP64
– buy XP64 (will give you the full 4GB)
– Overclock you CPU + good CPU-coolerAbout overclocking; normally I don’t tend to advise people to overclock, but the Q6600 is a case apart.
A Q6600 is easily overclocked to 3GHz without voltage adjustments and a good 30$ CPU-cooler. I’ve got 2 machines running at 3GHz and even Renderking does it 🙂Mac or PC doesn’t change a thing, buying a good machine just requires good money !
cya,
Jan
