I have been trying to get vista home premium 64 bit to run stable with 4x1gb of ram, but am unable to do so.
My system is,
amd athlon 64 x2 dual core 6000+
geforce 6800 ultra
4x1gb crucial ballistix tracer ddr2 6400 ram
asus crosshair M/B with latest bios.

It runs stable with any 3 modules in any 3 slots, but I get artifacts across the screen and games are unplayable with all four in.
I have tried kb929777 patch but still no good.
If anyone can help I would be most greatfull.
 
Holding my breath, as i'm planning on running 4 x 1gb RAM with Vista Ultimate 64bit...

You sure you don't have a faulty stick mate,i'm running 4x1GB sticks with vista 64 with no issues at all

Try memtest on the sticks just to be sure ;)

I had this problem too, try playing with the memory timings a bit, worked for me. Wouldn't even boot with 4GB before, just got BSOD at boot, but is fine now with all 4 sticks.
 
Memory modules seem to be ok. I have the timings currently on 4-4-4-12 2T
with voltage on 2.2v, these are manufacturers settings, but still the same problem. I have read that it could be the amd memory controller not liking anything over 3gb, but there was no backup to this claim.
 
I had similar problems with 4 x 2GB sticks.

After trying various solutions I narrowed it down to the BIOS not liking four sticks of memory. I'm currently running a beta BIOS and no problems so far.

My system is also Asus based - the V3-P5G965 barebones.
 
Yes but you will get between 2 & 3gb of useable RAM available to the OS. It will be nearer 2Gb if you have two graphics cards or a mass of addin cards
 
Vista Business X64 running fine here with 4 x 1GB

Certainly 2T is normally required. And I've also heard that sometimes you need to increase the northbridge voltage a little
 
I am using crosshair M/B, how much can the northbridge voltage be increased
without doing any harm, also I am using 2T on the memory timings already, and it is at 4-4-4-12 with voltage set at 2.2v which is manufacturers rating.
Still does not seem stable at the moment.
 
I have had my fair share of problems with RAM on this new computer using vista 64 bit but i think a lot of it is to do with my mobo, i finally have it working now, stable, i went through all the voltages and timings under the sun, any patch, updates everything, the thing that seems to have worked *touch wood* is setting the RAM to 667mhz in the BIOS and now it seems stable...again *touch wood*
 
I had problems with 4x1gb sticks og GeIL with my mobo. Used to bomb out on Memtest too. Tried every configuration under the sun, it refused to work with 4x1gb. 3x1 was fine, likewise 2x2gb. But would not work properly with 4x1gb. Even bought another mobo and tried it (The first was a 965p-DS3 1.0, the next a rev3.3) Did it on both. Luckily i needed 2 boards anyhow.
 
Stable

I had all the latest drivers for my 6800 ultra. I have bought and installed the bfg 8800 gtx card, installed all the latest drivers, and my system now seems stable with all four 1gb modules in. Can anyone explain why they think it now seems stable. They are set at 4-4-4-12-2T and 2.2v.

NO you can't! Just like XP you need 64 bit that will address up to 32GB

32GB - and the rest.
64bit can in theory address 16 exabytes of RAM (16,000,000 GB of RAM)
Most OS's do however place a hard limit between 8GB & 256TB
