Instability with 4gb ram?

[Guest Zootal]

Has anyone noticed any instability with XP64 when 4GB of ram that goes away

when using 2GB? I'm struggling with a random blue screen problem that seems

to go away when I run with 2GB of ram - any 2GB. The actual error varies,

and tends to be strange stuff like pfn_list_corrupt, etc., which usually

points to hardware problems. So far it seems to work fine if I run with 2GB,

and it doesn't seem to matter which memory sticks, or which slots they are

in. This makes me wonder if my mobo just can't handle 4GB, or if there might

be XP64 issues with that much memory?

There were some issues with Outlook and a couple of other applications and 4

GB, but not with XP x64 itself. However, there are a LOT of motherboards out

there that don't handle four DIMMs as well as they should. This can

sometimes be improved by tweaking the voltage up a bit to the RAM. And

motherboards that do fine with it today, may develop issues over time.

Especially if the power supply is a bit marginal, and you start to add

additional power using things to your computer. I'd also look for a BIOS

update from your mobo mfg - sometimes that can help.

Re: Instability with 4gb ram?

 

I'm currently playing with the memory voltage. I have another board, an Asus

M2A-VM that won't run unless I manual set the voltage to 1.8. then it's rock

solid. I'm not sure what "auto" means, it apparently isn't 1.8v. <sigh....>

 

I'm wondering if I should get a set of 2GB sticks, instead of trying to use

four 1GB sticks?

Re: Instability with 4gb ram?

 

Yup, if it will use 2 GB sticks, go that way. I've got an oldish A8V-VM that

is the mobo for my Windows Home Server, and I had to swap out the 512 Mb

sticks for a pair of 1 GB to get up to where I wanted to be for WHS - 2GB.

Nothing I did would allow it to even boot with 4 sticks in.

Re: Instability with 4gb ram?

 

With some motherboards it's a timing problem when all four slots are full,

not a voltage problem. Try running the RAM at a slower speed.

RE: Instability with 4gb ram?

 

seems like a board power distribution problem. some boards are notorious

for that like foxconn.

Re: Instability with 4gb ram?

 

It's an Asus board. However, that doesn't seem to mean much anymore - Asus

boards aren't as good as they used to be. That could very well be the

problem, since any two sticks run fine. Not sure what I can do about it,

though, other then get a set of 2GB sticks.

 

Hmm...here is a thought. the board comes with a set of memory heat pipes,

but they only cool two sticks. I wonder if they would make a difference? I'm

thinking not because I'm currently running the board with the cover off and

a fan blowing inside. That dropped the internal temp by about 10+ degrees

(telling me I have piss-poor circulation inside the box with the cover on).

There was no problem before I took the cover off, I just didn't like the cpu

temp hitting 130 degrees F.

Re: Instability with 4gb ram?

 

When all four RAM slots are full on many motherboards it's usually

necessary to relax your memory timings . If your command rate is at

1T (one clock cycle) then change it to 2T (two clock cycles).

 

Are your 4 memory sticks the exact same model? It is recommended that

the modules you use be of the same size, speed, arrangement etc.

Re: Instability with 4gb ram?

 

Time for a new (and better) box. A well designed enclosure should run cooler

when all the covers are on, not when you've got the cover off and a fan

blowing on it.

 

There are quite expensive enclosures, such as Lian Li, that have been

reported to be very good, and are certainly cool looking, but in a more

reasonable range, the P18x series from Antec made a huge difference on a

machine of mine that had heat problems. (see an old blog post of mine:

http://msmvps.com/blogs/xperts64/archive/2005/12/07/78351.aspx for details.)

Re: Instability with 4gb ram?

 

Funny you should mention Foxconn. I've used their boards for years with no

problems. The A79A-S, which I'm currently using, has an additional power

connector near the pcie slots, as well as a power connector for the cpu and

the main power connector. Maybe Foxconn finally got a clue? that they need

more power connectors to start with?

 

I'm finding the same thing as I found with my Asus board - two sticks are

stable, four sticks are not. I have a set of two 2GB sticks on order, due to

be delivered tomorrow, so I will find out soon if this fixes the problem.

 

Anyone have experience with Crucial memory? I'm replacing it with Kingston,

and I'm not 100% certain if a) one of the crucial sticks is bad/weak or b)

the boards really can't handle four sticks at once or c) the crucial is just

not a good design in that it is the reason I can't run four sticks at once.

 

I'm leaning towards the sticks being bad/weak/poor design. I notice that if

the case gets warm, but not unreasonably warm, they will fail diags and as

soon as they cool off they run OK. They are not getting too hot - just warm,

and they should work fine at the temps I've seen them fail at.

 

IOW, I'm still not sure if it's a bad memory stick design (Crucial), a

defective stick(s), or if the boards just can't handle four sticks, as

others have mentioned.

I've used Crucial memory for years. Very high quality, IME. And certainly,

if any of their memory fails, it's covered.

Re: Instability with 4gb ram?

 

I talked to Crucial about it and interesting enough, they told me to

increase the voltage on the sticks even higher, up to 2.2v, and said they

would most likely not run at 1066 with default bios settings. I ran with

2GB for a day, and at one time found my swap file was at about 800MB

usage...and I remember when 640k was a lot of memory lol.
