neilthewolf01 Posted May 31, 2009 Posted May 31, 2009 RAM problem Hi, hope I'm in the right section. I recently had to format my drive and re-install windows xp home due to a 'virut' in my system. Everything has gone great and everything is working as it should now....except for the RAM I'd installed a couple of years ago. My system is not recognizing the new RAM or should i say its not using it. In BIOS settings it shows that i have 1,500,00MB of memory. In My computer/system properties it only shows that i have 250MB of memory. In System tools/ system information it tells me that i have 1,500,00MB Total physical memory. But only 30.00MB available physical memory. I have tune up utilities installed and it also doesn't recognize the RAM installed. I have also been back onto crucial.com and it recognizes the RAM Before my problems with the virus the extra RAM i installed was working fine so i know its compatible. Is there anything that I've forgot to do in the format or re-install that would effect this. I have a intel pentium 4 cpu 2.80GHz on windows xp home. Oh and i have virtually nothing installed that could be effecting the memory. Any ideas? Thanks Neil Quote

Jelly Bean Posted June 1, 2009 Posted June 1, 2009 (edited) What is make and model of your mainboard,this maybe a mixed RAM issue as in size and speed or a dual channel mode issue? EDIT: Are you questioning the "Physical Memory" or the actual RAM showing in computer properties? Read this: Computer data storage - Wikipedia, the free encyclopedia Edited June 1, 2009 by Jelly Bean Quote Rwy'n ceisio fy ngorau......................
neilthewolf01 Posted June 1, 2009 Author Posted June 1, 2009 Sorry, mainboard is Dell computer corp. 02Y832 The main issue is pc is struggling when more than 1 application open. It seems obvious to me that the installed RAM isn't working. Before my format the RAM was showing up in my computer/properties now it isn't. When i originally installed the RAM i could see a notable improvement in my computers performance. I hope this explains. Thanks Neil Quote
Jelly Bean Posted June 1, 2009 Posted June 1, 2009 Have you updated drivers and installed the latest chipset? Quote Rwy'n ceisio fy ngorau......................
neilthewolf01 Posted June 1, 2009 Author Posted June 1, 2009 I have updated the drivers but i don't think I've put in anything about a 'chipset'. would this make a difference and if so how do i do it? Thanks neil Quote
zinglebarb Posted June 1, 2009 Posted June 1, 2009 if you pull the 2x 512 does it report properly Quote Q9550 P5Q pro mobo 4 gig pc8500 ATI 4870 Scythe CPU cooler Vista X64 5 HDDs 3 optical OCZ modular psu
Jelly Bean Posted June 1, 2009 Posted June 1, 2009 Remove RAM and place in the first two slots two matching sticks is it showing up? Quote Rwy'n ceisio fy ngorau......................
neilthewolf01 Posted June 2, 2009 Author Posted June 2, 2009 Have tried what you said and it shows up in bios settings but doesn't in computer/properties or in tune-up utilities. I have tried different combination's to but the same thing happens. Ive also updates chipset and drivers. Thanks Neil Quote
neilthewolf01 Posted June 7, 2009 Author Posted June 7, 2009 sorted. OS install mode was on in bios setup. Turned it off and suddenly pc recognizing ram installed. Anyone want to explain why. Thanks Neil Quote
Jelly Bean Posted June 7, 2009 Posted June 7, 2009 Oh excellent.Just wrong setting in BIOS. Quote Rwy'n ceisio fy ngorau......................
Tootech Posted June 7, 2009 Posted June 7, 2009 OS install mode was on in bios setup Didn't have a clue what this meant so I looked it up, and this is a quote from a Dell service manual. Turns the OS Install Mode on and off. The default is Off. When set to On, memory is limited to 256 MB to allow the installation of older operating systems that have 2 GB memory limits. Quote
