Mercury PI865GM memory problem

Hi All, 
I have a Mercury PI865GM Mother board.I have installed two modules of 1GB 400MHz RAM modules. But my system detects them as 333Mhz. How do I make my computer to recognize them as 400MHz. I know there is a jumper setting I need to change....but I lost my manual, hence do not know which jumper to change. 
Please help.

Dear Nagesh,
Its not a big issue, all Higher Frequency Rams comes with Backward compatibility, but this compatibility works with only branded Rams.

I have a 512 DDR2 (533 FSB) RAM in one of my slot in Intel D102GGC2 Mother board,can i put a 2 GB DDR2 ram in another slot.If yes then What FSB will match and what is the maximum capacity of ram per slot?


This motherboard will support maximum 2 GB of total system memory. so configuration is should be 1GB + 1GB or one 2GB in one slot. If you attempt to install 2GB + 512MB, this is unsupported. but you can try if might the system can read it or not. there is no serious problem for installing memory exceed than maximum system memory...
Memory supported is DDR2 533 Mhz and DDR2 400 MHz...(sometimes on the market DDR2 533 will described as module name PC2-4200 and DDR2 400 as PC2 3200)

Does ''FOXCONN 8657MF-series'' supports 400mhz fsb of RAM


Yes, you can add it. The faster 1 GB will be downclocked to the speed of the slower 256MB.
 But it would be better for performance to remove the 256 MB one completely.

Hi I also have a P4m800-M7 rev 3.1 motherboard and a 512mb of ram.. my question is, is it okay to put another ram but in 1gb size its pc3200, will it work? thanks!!


Hi,

The motherboard supports 2GB maximum memory. 1x1GB in each slot.

Maximum clock speed is 400MHz (PC3200), so the memory module you have should work fine.

Please remember to remove the power cord before installing the new ram.


Regards.

I have an asus k8v-mx motherboard running only 512 mb of ram what type of ram would suit this mother board and could i fit a 1 x 2mb ram instead of 2 x 1mb?


Dear Sir,

*********** 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.

good luck

HOW TO FIND RAM CAPACITY OF INTEL D102GGC2


Intel D102GGC2 Motherboard Each memory slot can hold DDR2 PC2-5300 with a maximum of 1GB per slot.*
Maximum Memory Capacity: 2048MB
* Currently Installed Memory: 512mb Number of Banks: 2
* Dual Channel Support: Yes
* CPU Manufacturer: GenuineIntel
* Although the memory can be installed one module at a time, the best performance comes from using matched pairs of modules.
Your MotherBoard Supports up to 2GB of memory.

You have 512mb, you can add 512mb to the empty slot.
, however,It's a good idea to keep them the same if you can.
You can install memory that is: DDR2 PC2-5300 (PC2-5300 is 667Mhz) you can use 1gb memory in each module for best performance and matching pairs since your motherborad supports dual channel.you can use sound card and SATA hard disk for higher disk support

PI865GM Memory issue


I cannot find anything in your motherboard manual about a jumper setting to change the RAM frequency. However, the only thing I can find is on the CPU PnP Setup Page in the CMOS setup utility that says DRAM Frequency (currently set to auto).. Perhaps you can try changing this to 400MHZ (if the option is available).

There may be a jumper setting somewhere, but without a proper photo of the motherboard, or a better manual, I cannot find it...

Upgrading ram


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.
Mike

Ram upgradation for 845glad mother board


Hi! If you have orignal Intel D845 then you need ram less than 333 Mhz (Around 266mhz or so) and do remember to check that it is advisable not to use RAM of more than 1GB as you won't be able to find a 1GB RAM(DDR1) with 266 Mhz or less.

RAM upgrate


you can upgrade to a max of 2gb on that board. These are your 1gb options: 1GB PC2700 333MHz DDR Memory, 1GB PC2100 266MHz DDR Memory, and 1GB PC3200 400MHz Non-ECC Unbuffered 184-pin DDR DIMM Memory. Install a set of any of these and your off and running.
