well I've been into the bios screen, its a whole new world in there and all of it goes straight over my head other than boot sequences. I went into the screens that indicated anything to do with memory and this is what i found. CPU clock ratio 8 cpu host/pci clock default OS select for DRAM > 64MB Non-OS2 Base memory 640K Extended memory 523264K Total memory 524288K DRAM timing selectable By SPD DRAM RAS# to CAS# Delay 3 DRAM RAS# precharge 3 DRAM Dat integrity mode Non-ECC I'm sure that there is a lot more but is this of any use:confused:

I really appreciate all of this help. I dont mind having a look in the BIOS if there is some guidance. Providing I dont change anything then I guess its ok. I understand that updating the board could turn it into junk so I'll just look and not adjust anything. Can you remind me what keys I press to enter the settings screen.

I ran something else last night and this is it. In addition I found the manual but it looks as though they have grouped the boards together. I agree it does look as though they will all take more memory than I am trying to install so does that mean that something is broken.:D Operating System System Model Windows XP Home Edition Service Pack 3 (build 2600) Enclosure Type: Desktop Processor a Main Circuit Board b 1.70 gigahertz Intel Pentium 4 8 kilobyte primary memory cache 256 kilobyte secondary memory cache Board: Legend QDI PLATINIX-2 V1.XXBus Clock: 100 megahertz BIOS: Award Software International, Inc. 6.00 PG 08/27/2001 Drives Memory Modules c,d 120.02 Gigabytes Usable Hard Drive Capacity 76.41 Gigabytes Hard Drive Free Space SAMSUNG CDRW/DVD SM-352B [CD-ROM drive] 3.5" format removeable media [Floppy drive] WDC WD1200JB-00GVA0 [Hard drive] (120.03 GB) -- drive 0, s/n WD-WCALA1647667, rev 08.02D08, SMART Status: Healthy 512 Megabytes Installed Memory Slot 'A0' has 256 MB Slot 'A1' is Empty Slot 'A2' has 256 MB Local Drive Volumes c: (NTFS on drive 0) 120.02 GB 76.41 GB free Network Drives None detected Users (mouse over user name for details) Printers local user accounts last logon Matt 18/02/2009 18:52:18 Pauline 18/02/2009 21:25:39 (admin) Rachael 17/02/2009 21:35:11 (admin) user 19/02/2009 17:15:47 (admin) local system accounts Administrator never (admin) ASPNET never Guest never HelpAssistant never SUPPORT_388945a0 never Marks a disabled account; Marks a locked account HP DeskJet 840C/841C/842C/843C on LPT1: Controllers Display Standard floppy disk controller Intel® 82801BA Ultra ATA Storage Controller - 244B Primary IDE Channel [Controller] Secondary IDE Channel [Controller] NVIDIA GeForce 6200 [Display adapter] Samsung SyncMaster [Monitor] (17.1"vis, s/n HJDW200713, February 2003) Bus Adapters Multimedia Intel® 82801BA/BAM USB Universal Host Controller - 2442 Intel® 82801BA/BAM USB Universal Host Controller - 2444 NEC PCI to USB Open Host Controller (2x) Standard Enhanced PCI to USB Host Controller Intel® 82801BA/BAM AC'97 Audio Controller MPU-401 Compatible MIDI Device Standard Game Port Communications Other Devices Motorola SM56 Speakerphone Modem 1394 Net Adapter NETGEAR GA311 Gigabit Adapter Dhcp Server: 192.168.1.1 Physical Address: 00:14:6C:CB:3F:7D NETGEAR WG111T 108Mbps Wireless USB2.0 Adapter #2 primary Auto IP Address: 192.168.0.2 / 24 Gateway: 192.168.0.1 Dhcp Server: 192.168.0.1 Physical Address: 00:14:6C:ED:66:10 Networking Dns Server: 192.168.0.1 VIA OHCI Compliant IEEE 1394 Host Controller Standard 101/102-Key or Microsoft Natural PS/2 Keyboard Microsoft USB Wheel Mouse Optical USB Root Hub (5x) Virus Protection [back to Top] F-Secure Client Security 7.10 Version 7.10

Thanks for the update, cant you sleep or are you working nights:D

Many thanks for the reply. No I havent done that yet. Slot 3 has never been used but as the scan says, I think, both original modules were in slots 1 and 2. I will try the alternatives and let you all know the outcome. Would you expect the mother board to be capable of handling the extra 512meg module and are there any other more technical things that need to be done. I read somewhere something about voltages and things within BIOS and god knows what else, all of it straight over my head.:rolleyes: Nebraska, my word what time is it there and I'll bet its bloody cold:D

Hello everyone, This is driving me nuts so here goes. This is the result of a scan on my computer.... 256 MB SDRAM, PC133 256 MB SDRAM, PC133 EMPTY 256 MB SDRAM, PC133 256 MB SDRAM, PC133 EMPTY Maximum Memory Capacity: 262144 MB Currently Installed Memory: 512 MB Available Memory Slots: 1 Number of Banks: 3 Dual Channel Support: N.A. CPU Manufacturer: GenuineIntel CPU Family: Intel® Pentium® 4 CPU 1700MHz Model 0, Stepping 10 CPU Speed: 1693 MHz Its running XP Pro and is working very slowly so a ram upgrade seemed appropriate. Upon investigation there were two different 256meg manufacturers memory in two of the three slots. I purchased a single 512meg upgrade from Orca.... 512MB Module Orca Part Code: 64MLS64V6F-B49 standard 168-Pin DIMM PC133 (133MHz) ( RAM ) I now had over 1g of RAM but the PC would not boot, or at least it did eventually but very slowly, took out the old stuff and bingo on it came, took out the new stuff and replaced it with the old and bingo again. I rang Orca and we decided that another matching 512meg lump would solve the problem. That arrived, put it in and nothing, well eventually it booted but slowly. Took out the first 512meg upgrade and bingo, took out the second 512meg upgrade and bingo again. So individually they work but together or as soon as it goes above 512meg then nothing. I have checked on the motherboard manufacturers site and this is what it says.....

Is it possible that the board will only take 512meg? The scan says otherwise so what is wrong/'
