RAM Problem : Please Help

[subratabera]

Hello everyone,

I have a computer with Celeron 1GHz processor, 128 MB RAM, Mercury 810 series motherboard. Recently I have installed an additional 128 RAM with same specification of my previous RAM (133 MHz, Hyundai), but after that my system become very slow while booting (particularly Fedora core 5) and sometimes during normal use (Windows XP). When I run my system on single 128 RAM (on any empty slot or any one RAM card), it works fine. But when I install both my RAMs, it just slow down my PC. Can anyone suggest what is the real problem and also possible solutions.

Thanks in advance...

not always havin the same config. the two modules will work fine b'coz the manufacturers r diff......

try out both RAM individually , if both the RAMs works fine that means thay r not supporting each other....

the only suggestion i can give is CHANGE UR PC.....

i m sorry to say that but at that config. it's just a crap.....

Thankyou very much for your help and suggestions Ayush...
By the way I am also thinking of changing my PC, but when something new and different will come into market like MRAM.

Thanks one again...

have heard bout XRAM but no MRAM??whats that stuff?
Many thing new has come after the SDRAM..like DDR, DDR2 nd DDR3[on cards].
What r u waitin for??There is a hell difference b/w SD nd DDR2.

Hello aravind_n20,

Here is some info on MRAM for you.

MRAM
------
Magnetic RAM, a new memory technology that promises to provide non-volatile, low-power, high speed and low-cost memory. Often described as the 'holy-grail' of memory, MRAM has the potential to replace FLASH, RAM and even Hard-discs.
MRAM is a memory (RAM) technology that uses electron spin to store information.
MRAM has been called "the ideal memory" - potentially combining the density of DRAM with the speed of SRAM and non-volatility of FLASH memory or hard disk, and all this while consuming a very low amount of power.
MRAM can resist high radiation, and can operate in extreme temperature conditions. It is likely that we'll see the first MRAM in applications that need such properties.
MRAM requires less far less memory refresh than DRAM - leading to better power consumption. It is also speed-competitive with SRAM (the cpu CACHE memory). So MRAM can mean much more storage in mobile devices, with longer battery life. MRAM will eventually be made in high densities, and will perhaps replace your computer's HD - leading to a fast computer that can instantly be turned on.
MRAM normally functions by constructing minuscule magnetic fields at intersections in a grid of nanoscopic power rails. When current attempts to travel through a power rail which is opposing the polarization of one of the magnetic field bits, its current flow is mitigated and the bit value stored by the field is detected by this weakened current flow.

MRAM wont hit the market anytime soon. its just a conceptual technology. First intel and AMD will push all limits of DDR2 and when the DDR2 tech will hit the max capacity; only then will they look into other techs.

Thnx a lot.guy.....an entirely new info.

Hello everyone,

I have fixed the problem with a little GRUB tweak...Here is how...
I just added mem=224 to the kernel line of my grub.conf file...

root (hd1,4)
kernel /vmlinuz-2.6.15-1.2054_FC5 ro root=LABEL=/ rhgb quiet mem=224M
initrd /initrd-2.6.15-1.2054_FC5.img

and that's solved my problem. Now my system (Fedora Core 5) is as fast as before.
