I have the mach speed P4M800CE mb. I recently upgraded my memory from 512mb to 2gb. I installed ocz Platinum 2gb (2x1gb) 184 Pin ddr sdram ddr400 (pc 3200) Dual channel memory.
When I check the memory in System Information - It lists Total Physical Memory at 512 mb and Available Physical Memory at 1.43 gb. How can I have more Available Physical Memory than I have Total Physical Memory ?
It sounds like something isnt working right, what operating system are you using, Vista? I would take out the original 512 and see what it says after, often ram isnt compatible if it is too different in size and speeds. Also, if your motherboard supports dual channel ram and you have the extra 512 chip it wont run in dual channel mode, you would run better with just the 2 chips then the added 512 chip.

*********** board is Asus old p4 Mother board.It supports maximum 1GB RAM of DDR 400(DDR1). According to your post your computer having only one 512 MB working RAM. If you want good purformance you can upgrade your computer by purchasing another 512MB DDR400 RAM and install it on another RAM slot.If your computer have only one working RAM slot,you can purchase 1GB DDR400 RAM & install it on older RAM place. I think it solves your problem.if you have any problem come back with more information. I will try to assist you more accurately.
This is the website link for your board on gigabyte website. http://www.gigabyte.com.tw/Products/Motherboard/Products_Spec.aspx?ClassValue=Motherboard&ProductID=2159&ProductName=GA-8VM800PMD-775
Suggest you have a faulty piece of ram or a clock speed miss-match. your board supports up to 2gb of memory.Try also reseating the memory.
Let me know how you get on?
HI there. There are loads of makers of memory and graphics cards out there to choose from. For the ram i would recommend Corsair or Kingston, you can get this ram as a matching pair so the both run at the same speed, the best ram to get is DDR 400. As for the graphics card, i recommend ATI radeon X1650 Pro 512MB graphics card. These upgrades will make your machine purr like a kitten with an excellent gaming experience.
Hi dwman113, Yes your Mach Speed MB will support 2x1 GB, Dual Channel Mode DDR2-800MHz, PC6400 memory modules. (Manual states the memory dimms should be paired). Also known as matched memory. Max Shared Video Memory is 256MB, refers only to the integrated built in video card. Click this link to help you understand what CL stands for; http://www.hardwaresecrets.com/article/26/3 Small example. CL3 runs faster than CL5. You can run any PCI-Express 16x graphics card & it can be rev 2.0. Graphics cards are backwards compatible which means it will also run at v1.0. You should not buy a SLI card because you only have 1 PCI-E x16 slot. To run SLI, (Hooking up 2 PCI-E x16 cards together viva a small SLI connector) your motherboard would need two PCI-E x16 slots & the board must support SLI mode & your's does not. Here is the main web site link for your Mach Speed MSA2-6100V MB. http://www.machspeed.com/specs/viper/MSA2-6100V.html If you have any more issues or questions just post it & we'll go from there.
Some MOBO support different type of memory modules like ddr 400, 333,533 and other, if your computer is working fine with that PC400 it only means that your MOBO is compatible with it. Since you're planning to upgrade the memory just get another PC400 because the memory should be the same to work fine.
Hi reisrui, yes it is odd. (It's not the first time I have seen this.)
According to you're manual on page 6, under Specifications. The manual say's you can run up to a Max speed of PC3200 400MHz, 1GB in slot one. In slot 2 you can run a Max of 1GB of PC2700 333MHz in slot 2. Every motherboard I have come across that can run two different speeds of memory. The system will reduce the Max speed to the lower MHz memory speed. If you currently are using 512MB PC3200 400MHz in slot 1 & add 1GB of PC3200 400MHz into slot 2 for a total of 1.5GB of memory. The motherboard will ruduce the total memory over all speed to PC2700 333MHz. Motherboards alway run at the lower memory speed if two different speeds are presant.
I can’t be 100% sure of the 1GB of PC3200 400MHz into slot 2, will run at all! Or if it will be reduce down to 333MHz. I am sure you can run 2GB of PC2700 333MHz, 1GB of memory per slot in you're board for a total of 2GB.
If I can help you further, feel free to post. Suggestions & comments welcomed.
