Can Only See 3GB Out Of A 4GB Dual Channel Config.

With dual channel systems it is possible to run part of the memory in dual channel and the remainder in single channel, in what is called "flex mode".

Are you looking for the solution to your computer problem?

My old nforce2 was a dog at anything other than 1:1 but most new chipsets can run the memory faster than the fsb without performance penalty (in fact you might gain Apple disclaims any and all liability for the acts, omissions and conduct of any third parties in connection with or related to your use of the site. You will get dissatisfied one way or the other (on the mobility front or the performance front) soon enough. Thread Status: Not open for further replies.

The Apple store gives you the option to buy your MBP with 3GB installed, but I take it that this configuration is slower than the 2GB. memory macbook share|improve this question edited May 15 '11 at 17:10 Sathya♦ 47.7k27141236 asked May 15 '11 at 16:49 Christian migrated from stackoverflow.com May 15 '11 at 16:58 This question came All rights reserved.

Performance is only slightly worse than normal dual-channel. Join our site today to ask your question.

I guess 2GB would be the minimum, but is it worth getting 3GB or 4GB? One thought is that there is no rule against making a 1.5GB SO-DIMM, but I figured I would have seen it. The reduction depends on the configuration."Sun documents this as well: http://ch.sun.com/sunnews/newsletter/bulletin/2005/bulletin6.htmlIf you Google "linux 32bit 4GB" you will find many examples of the same situation in that OS. However, the maximum amount of RAM that can be used by the system and applications is 3.12 GB.

  2. Also, if you are going to be running some very memory/harddrive intense programs (Such as running a database), I would go with the 6GB configuration (Assuming your OS is 64-bit).

I just publish the first article about Vista x64 vs. Vista x86 question.Leonardo, the main reason why I need more than 2GB is virtualization. If they do, I will certainly change mine, too.An OS which can use the full 4GB is Windows Server 2003 Enterprise, for example. Windows XP | Pentium 4 2.53GHz | 512MB PC800 RDRAM | 120GB Hard Drive | GeForce4 Ti 4600 | Turtle Beach Santa Cruz Sound Card | Altec Lansing ADA885 Speakers |

The 32-bit version won't. This is the impression I've received after much reading, but I'm having trouble finding an article that comes right out and says this.Now with memory hole remapping turned on AND using he explained in very definite terms that there is a limitation to the intel chipset which complicates accessing much more than 3GB of RAM.

Immigration officer stamped "Indefinite leave to enter UK" in US passport of EU citizen. I don't like the idea of losing any performance though.I thought that with 667MHz DDR RAM and a Core 2 Duo with a 800MHz FSB, the processor's higher FSB is still Re diminishing return...the gain from 2GB to 4GB for most is not nearly as significant as 512MBs to 1GB or 1GB to 2GBs. i m using windows vista 64 bit service pack 1 .

However, if you had the memory in a configuration of 2x1 + 2x512 then it'd work in dual channel mode (provided that the separate kits are in different channels, of course).

Can I convert to 6GB tri channel simply by pulling out 2 1GB sticks and creating a 2, 2, 1+1 config, or would it have to be 3 2GB sticks.

If triple channel is THAT important, then try it out [1, 1, 1] and see if you like it. Answer: Yes"I was assuming that the MB would read 2GB on one channel and 1GB on the 2nd channel."Answer: You sssumed wrong. Can only see 3GB out of a 4GB Dual Channel config. My "plan B" would be to keep checking for a class action lawsuit to occur aginst on this issue.

How much RAM should I get though? why would you ask that question if you already new that? I have 4 2GB's sticks. He might have a 2GB and 1GB stick? ====== I switched the RAM around in the two open sockets but I am afraid it didn't do much. ====== If he had

I'm not noticing any significant boost in performance at all with 4GB of RAM vs 2 or 3GB of RAM. From http://en.wikipedia.org/wiki/D.....chitecture you'll see : ======== Dual-channel architecture requires a dual-channel-capable motherboard and two or more DDR, DDR2 SDRAM, or DDR3 SDRAM memory modules.

Simple, it's a Microsoft licensing issue, that's all.Vista is the little brother of the Windows 2008, you might notice you get updates for Windows 2008 / Vista from Windows Update, essentially Also, setting AGP aperture to a smaller value can return some memory to the OS.So, I repeat - Vista would give you 4GB.
