Guest razor Posted June 17, 2008 Posted June 17, 2008 Hello-- I have a new PC with Windows XP Pro on it and 4 GB or RAM for when I upgrade to 64-bit. In Windows 32-bit it is only showing 2.5 GB and I thought 3 or 3.5 was the max. I posted to a different forum and they said there is a switch or something I can add to show the max RAM. Does anyone here know about that? Many thanks, sd
Guest R. McCarty Posted June 17, 2008 Posted June 17, 2008 Re: What is the Switch to Show Maximum RAM? Boot.Ini - add /PAE However, even without that qualifier XP should natively see more than 2.5 Gigabytes. Was it home built or purchased from an OEM ?

I'm surprised its down to 2.5.
Guest razor Posted June 17, 2008 Posted June 17, 2008 Re: What is the Switch to Show Maximum RAM? Wow, you're good. Yes, it is a custom build and they used an OEM version of Windows XP Pro. I just got the rig yesterday (which was not cheap) and it is so unstable I could scream. It keeps crashing to either reboot or frozen screen. I have 30 days to get it stable or I get a full refund, but you know what a total pain that can be. I just started reading event logs and see system errors--which is not good. But I have to tackle one issue at a time. If you have any suggestions for how I can stabilize this system, I am all ears. Thanks for the switch too. sd "R.

Guest R. McCarty Posted June 17, 2008 Posted June 17, 2008 Re: What is the Switch to Show Maximum RAM? I'd concentrate on resolving the Event Log errors. New & Unstable isn't a good thing. Your Out-of-Box experience shouldn't require a detailed review to get things working. I'd be interested to know the primary hardware ( MB, CPU, Video ) to understand why the RAM count is below 3.0 Gigabytes. Regardless of the specs, you might want to install SpeedFan 4.34 to check temps. I've seen lots of new builds where the CPU heatspreader isn't properly covered in Thermal paste or the CPU Heatsink is poorly seated. Your instability could be due to overheating.

Guest razor Posted June 17, 2008 Posted June 17, 2008 Re: What is the Switch to Show Maximum RAM? Yea, I've thrown more stable PCs in the trash. The thing is very well cooled (in theory) with a huge Asus cooling system as well as 6 other fans in a Cooler Master well ventilated case. I use speed fan at work though, so I'll install that and see what is says. I haven't even done any strenuous with the system. It crashes during Windows security updates...etc. Here are the specs of the rig: NVIDIA 780i SLI nForce mobo and chipset dual NVIDIA 8800 GT SLI vid cards with 512 memory each Intel Core 2 Quad 9450 CPU WD 10,000 SATA HD. 4 GB Corsair 1066 Dominator RAM. Thanks. sd BTW. I'm not sure where to apply the switch for the RAM. Can you break down the config for me? "R. McCarty" wrote: > I'd concentrate on resolving the Event Log errors.

Guest R. McCarty Posted June 17, 2008 Posted June 17, 2008 Re: What is the Switch to Show Maximum RAM? Edit Boot.Ini, in the [Operating Systems] listing just add the /PAE to the end of the Windows XP call line. That's very Top-Tier hardware, wouldn't expect there to be stability issues at all.

In Windows 32-bit it is only showing 2.5 GB and I thought 3 or 3.5 >was the max. It depends. Some of your 4GB address space must be used to access your video RAM, BIOS, etc. That means that you will not be able to access all 4GB of system RAM. You're right that it usually works out to some thing like 3 - 3.5GB, so something's taking quite a bit of space. Do you have multiple video cards with lots of RAM? See http://members.cox.net/slatteryt/RAM.html >I posted to a different forum and they said there is a switch or something I >can add to show the max RAM. Does anyone here know about that? Don't bother with the PAE switch. XP uses PAE only for the DEP (Data Execution Prevention) facility, not for the expanded address space. MS Server systems use PAE for expanded address space, so does Linux. Not MS client systems. And the /3GB switch affects allocation of virtual memory and has nothing at all to do with physical RAM. -- Tim Slattery MS MVP(Shell/User) Slattery_T@bls.gov http://members.cox.net/slatteryt
Guest razor Posted June 18, 2008 Posted June 18, 2008 Re: What is the Switch to Show Maximum RAM? Well, you're batting 1,000. The cause of the issue became more evident when I started hearing a strange grinding sound coming out of one of the top fans. When I removed the siding, I saw that the heat sink brace lever was sticking into the fan. I barely touched it to get it out of the fan, and the whole heat sink came loose. The crashing must have been happening due to the lack of heat sink contact with the CPU. I tried to maneuver around inside the case to re-seat the heat sink, but it is ginormous and there was not enough room--not to mention it looked like it needed more thermal grease and I don't have any. The only way I could have done it myself was to practically dismantle the entire rig--so back to the manufacturer I go this Friday. It will be an amazing inconvenience, but the system was over $2k US and there is no way I will tolerate that kind of instability out of a brand new system. Thanks to all for the help! sd "R.
