I built my PC about a year ago. Specs: MOBO: GIGABYTE GA-965P-S3 LGA 775 Intel P965 Express ATX Intel Intel Core 2 Duo E6400 Conroe 2.13GHz LGA 775 Processor Model BX80557E6400 CORSAIR XMS2 1GB 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Desktop Memory Model CM2X1024-6400 I wanted more RAM, but didn't have enough money at the time. I recently bought 2GB more of the same except its dual channel and 4-4-4-12 instead of 5-5-5-12(the orig) Does the difference in timing matter? I placed the dual memories in yellow slots 1 and 3, and the old one in red slot 2, and red slot 4 empty. Do I need all four slots covered? The bios at start up says its in flex memory mode, but when I go to My computer,view system information,general it says I'm only running on 1.00 GB of RAM, instead of the 3 GB I have installed. Any advice? THANKS!
Hi, I reckon you should check there is no issues with your RAM first. check each stick on its own by removing all memory and rebooting the PC, using a single stick of RAM each time. If all works no probs, it looks like a config issue. I have just read about the Flex Memory option and found this: - Flex Memory Technology, a feature that allows differing sizes of memory modules to be installed, while maintaining the dual-channel DDR2 operating mode, so you can stay with 3 sticks in dual channel and should have the same performance. Flex Memory Technology where it can be configured to support single-channel or dual-channel DDR2 memory configurations. Depending upon how the DIMMs are populated on each system memory channel, a number of different configurations can exist for DDR2: • Single Channel – only one channel of memory is routed and populated, or if two-channels of memory are routed, but only one channel is populated; can be either channel A or channel B. • Dual Channel Asymmetric – both channels are populated, but each channel has a different amount (MB) of total memory. • Dual Channel Symmetric – both channels are populated where each channel has the same amount (MB) of total memory. If there seems to be no issues with the RAM used individually, I would again try the system using Dual Channel (only the new 2x1Gb Sticks), then if this works add the remaining RAM a stick at a time. This will eliminate faulty RAM, faulty RAM sockets, and only leave configuration as the possible problem. If this is the case maybe someone who has more experience with this motherboard / setup can help you.
if you still have the MOBO manual read carefully the section on memory sometimes main boards have special rules when messing with RAM ie: anything over a billion Megabytes of ram has to be in large modules and only placed in 0 & 1 banks
OK. It seems I got it to recognize all the sticks now, but not using full capability. Here are BIOS: Total Physical Memory: 3,072.00 MB Available Physical Memory: 595.79 MB Total Virtual Memory: 2.00 GB Available Virtual Memory: 1.96 GB Page File Space 2.40 GB How do I change the settings? What is Page File Space?
WB pmaknelho! Your post doesn't seem to make sense unfortunately. The Page File is a method used by Windows, to utilise some of your hard drive storage as virtual memory for Windows. It can basically turn your disk space into memory to use for applications etc. Your BIOS shouldnt be reporting the size of virtual memory Windows allocates for the page file since the BIOS is viewd in your BIOS settings, which means Windows hasnt yet loaded? Are you sure your posting the correct info? It seems to be recognizing your 3Gb RAM (2x 512Mb, 2x1024Mb) in total, but says only 2Gb is available. Have you configured your motherboard to use 1Gb for other things like the onboard video etc?
