p5w dh deluxe & 4gb ram

Kimbo · 09-05-2006, 12:53 PM

i have read some information regarding the 4gb barrioer for 32bit systems before (http://blogs.msdn.com/oldnewthing/ar...14/699521.aspx).

so if i was to get 4gb ram (4x1gb sticks) then even in the worse case scenario the system would always see 3.5gb of memory, right ? or thereabouts. so even thou i loose half a gigabyte, 3.5gb is still better then 2gb. agreed ??

and would this missing memory affect dual chanel memory ? would it force it into single chanel ?

has anyone got an asus p5w dh deluxe with 4gb ram ?

I do not have that board, but there really is no problems associated with running 4 sticks of ram, just a slight drop in synthetic memory performance. Although unless you are doing some massive photo work, there really is not an advantage to running 4GB.

what i wanted to know exactly thou, is what this setup shows in winxp (32bit), i think it would show 3.5gb ram not 4gb.

XP likely will tell you that it is 4GB, but it can't make use of it. I read somewhere that XP can only address 3GB.

with my amd machine when i tried 4gb of ram it read like 3.28gb or something like that. never read 4gb.

ok well that i know, so even thou 4gb (3.x under 32bit os) is "overkill" in principale for the new BIG games (ut 2007, alan wake, crysis et al) 3.2 is "better" then 2gb or in fact 1.6. (because on a 2gb system about 400mb may be used by the os and drivers and such)

i wanted to know because if i did another upgrade of memory it will be the last memory upgrade for a while. so i'm thinking get 4gb of corsair dominator 8500c5 for like $1400 and that will last for 2-3 years.....

I'm about to. Vista 32 bit supports 4 gb. of ram. Home Basic will support 8 gb. max and Home Premium will support up to 16 gb of ram. XP 32 bit will see about 3 gb.

1. keep me informed.... are you going to install xp as well ? i suppose... vista is not ready for prime time.. take a screenshot of the windows system task manager (tab 3), performance after you have 4gb please and post it here.

2. so with these big games (crysis et al) 3 gb surely is better then 2 gb. (and i still think from what i have read that it's more like 3.5gb) so having 1.5gb extra as opposed to a 2gb system makes sense... for a system that will last 2-3 years (maybe) yes yes ????

I will keep you informed. I was going to install xp x64 and see how everything works. If it works out with the drivers, programs and games then I will keep that installed and dual boot with vista RC2. X64 will see the full 4gb. Vista will definitely take advantage of all that ram. If x64 gives me problems, then I will install 32 bit xp.

Kimbo · 10-27-2006, 12:53 PM

yeah, xp is the one i'm really interested in, not vista or xp 64 because we know they can address haps of ram....

when are you doing the upgrade ?

Probably within the next couple of weeks. I have pretty much decided what parts I am buying. If nobody has an answer before then, I will throw xp 32 bit on it just to see what happens with the ram. I am curious about it too.

Kimbo · 12-17-2006, 04:32 PM

hey jericho ???
did you get it ??? i suppose not ??

Jericho_abx · 12-17-2006, 06:43 PM

I had alot of trouble with the p5w dh deluxe. I received 2 bad ones and now they are sending a 3rd which I am going to sell. I bought an abit aw9d-max and it works great. No problems at all.

32 bit xp and 32 bit vista only see the 3 gb. of ram. You have to use xp x64 or vista 64 bit to see and make use of the 4 gb. of ram. Sorry, I didn't reply sooner, but I completely forgot about this thread.

The OS maps a memory range for PCI devices and such, in the (IIRC) upper memory range. This is static and part of how a PC (or at least Windows) manages memory-mapped devices. Therefore a 32-bit (Windows) OS will only be able to utilize 3.whatever GB of RAM, since the rest is used for memory-mapping.
