Title: 4GB vs 8GB
Post by: Telstar on July 02, 2009, 01:55:23 am
Somebody said that he heard differences raising the memory up to 8GB, then the differences where gone (diff software so apples and oranges).

Because DDR2 and 3 is dirt cheap nowadays, anyone tried or can try this on his computer?
I planned to get 4GB for my dedicated computer, and with xxhe architecture more shouldnt offer any improvement.

hmmm

I tried to read it upside down, but still don't understand. Was it too late for you, or is it too early for me ? :whistle:

Btw, I tried with 0 GB. Completely black. Of course this is a virtue of the memory player. :yes:

Probably me... :D
Anyway i meant physical ram not pagefile.

No, that is not what I meant. I just can't get what you are saying.

You probably don't want to say that differences kept on being there until the boundary of 8GB was surpassed (like from 8-12 GB it didn't matter anymore).

So, just adding more memory makes a difference is your message ? (but what about the 8GB then).

Anyway, to my own (XXHighEnd) experience, using less memory is also good for SQ. But, there may be a technical reason for this, like using less mapping (address space can be indirect). I did't investigate whether this still may apply, but if you think of old Dos days it mattered (tricks to get over the 640MB boundary).
This is one of the reasons the whole memory management was put up side down, and it helped indeed (SQ).

Personally I think it is all too complex to work out, but despite I never tried it, I will believe that stuffing in more memory (without the need to utilize it !!) will improve SQ.

Instead that's exactly what i wanted to say :)

Title: Ram problems
Post by: AUDIODIDAKT on July 04, 2009, 04:22:32 pm
finnaly,

I took my PC apart,
Because still having those BSOD 's everyday

And whatteyouknow - faulty RAM (this going on for 4 to 5 weeks now, OS could have errors too and have to check all my FLAC that I have moved around from disk to disk) :sad:

But cannot exactly determine witch RAM or maybe MB slot
Want to make sure witch one is the faulty

When testing all 2GB Ram seperately nothing to be found
Problems start with 2x2GB (now having 6GB and everything is fine and pc is already running 24 hours without problems)

Is there a better way to test this then memtest.exe ?

And can it be that, going from 8GB to 6GB (memory adressed as "Flex" instead of Dual channel interleaved) sound diffferent.
Can't say for sure, but have the feeling it does.
Too short to say. (or maybe it doesn't)

Grtz

memtest x86, from bootable cd.
2h at least. One ram bank at a time.

Sorry, there is no better choice. Once i brought two dimms to a shop and let them test cuz i didnt have a working pc at the time. I was lucky that they did it for free :) One was faulty and i got rma from crucial in <1month. Of course in the meanwhile i already bought other faster dimms and sold the crucials when i got them from rma :D

RAM errors are VERY common, even if you dont overclock them.

I think 8 > 4 is the absolute fact that the extra sticks of mem help cut down on vibration on the MB, And! by plugging up the 'holes'/empty-slots that are usually left open to take in all kinds of 'interference', they/extra memory acts like a shield!!... well then, there you have it. :)

just wanted to let you know it doesn't matter for SQ.
2GB, 4GB, 6GB, 8GB, it al sounds good to me.

Tnx for feedback.
I suspect that 4G+ sounds better with not tweaked OS, where lots of resident cr*p suck resources.
