System memory FSB

I have been using intel 915glvg motherboard since 2005.It have 4 slot for memory. It supports for 400mhz FSB for RAM. I was using 512MB ,400 Fsb Hynix RAM.Recently I upgraded it to 1GB RAM .For this i installed a new 512MB RAM(400FSB) (which is not hynix brand) in another slot.But now my system shows that system memory speed is 333 FSB. When I remove any one out of them then system show 400 FSB.Why it is happening. The sencod RAM that I have used is not of Hynix brand.My old Hynix 512 Ram consists 8 ICs on it while new RAM which i have installed consist 16 ICs(8 on each side) on it.

Re: system memory FSB

Have you tried installin the memory in various 1,2/1,2/1,4 etc?
Its sounds like your mother board is unable to run the sticks at the rated speed as they are different brands and densities so its dropping the speed to 166.

Have you tried going into the bios and changing the ram speed there?
Also try changing the command rate from 1T to 2T to see if that helps.

Emachines t3516a memory upgrade

The eMachines T3516 uses an Intel D101GGC motherboard,

Two Ram Memory slots.
Maximum Amount for EACH ram memory slot is 1GB.
Maximum TOTAL Amount for the motherboard is 2GB.

Ram Memory used is DDR Sdram at 333MegaHertz, or 400MHz.
That is PC-2700 and PC-3200 respectively.

Uses Non-ECC, low density, Unbuffered, CAS Latency of 2.5, and 2.5 Volt.

Dell dimention 2350 socket 478 I upgrade celeron 2.0Ghz to pentium 4 3.0Ghz 530 The Bios show me the speed 1.5Ghz. Bios A02

The Dell Dimension 2350 Desktop PC motherboard, has an Intel 845GL motherboard chipset,
mounted to it. (System Information),

Here we see that the Intel 845GL chipset supports processors, with a -> maximum <- Front Side Bus of 400MegaHertz, (FSB = 400MHz max.),

The Intel Pentium 4 model 530 (3.0GHz. Also has Hyper-threading Technology. HT), operates with a FSB of 800MegaHertz, (FSB = 800MHz),

(Scroll down. Pentium 4 HT 530 )

You can't make the Intel 845GL chipset support a processor with an 800MHz FSB.
BIOS update or not, the voltage range will be too low. Therefore the FSB is low. Changing just the Multiplier will not do the trick either.

(BIOS Setup, Advanced Chipset Setup. Doubt the options of changing the FSB, and/or Voltage, and/or Multiplier, is available with that BIOS program))

Note your 3.0GHz processor is operating at 1.5GHz?

Max FSB supported is 400MHz, and your Model 530 needs 800MHz? (For max operation)

Post additional questions in a Comment.


[ Chip and Chipset are shortened terms for I.C.
Integrated Circuit,

The motherboard chipset technology used for your computer, has a Northbridge chip, and a Southbridge chip.

(Does not apply to motherboards that support the Intel Core i3, Core i5, Core i7, and Core i9 processors )

The Northbridge chip handles the faster capabilities of a computer.
Processor, Ram Memory, and High-speed graphics.

[ The AGP technology, and the PCI-Express technology, is High-speed graphics.
Using a graphics card in a PCI slot, or using Integrated Graphics, is NOT High-speed graphics ]

The Southbridge chip handles the slower capabilities of a computer.
Anything connected to the PCI bus, (Such as a PCI graphics card)
Audio (Sound)

[ CPU stands for Central Processing Unit. Another term used is Microprocessor, or Processor for short ]

So it is first up to the Northbridge chip, of the motherboard chipset, whether it will support a certain processor, THEN if a BIOS update will help.

Will pc2-5300 memory work in emachines t5082?

Yes it will work

Memory Type: DDR2 PC2-5300, DDR2 (non-ECC)
Maximum Memory: 2GB
Slots: 2
Each memory slot can hold DDR2 PC2-5300 with a maximum of 1GB per slot.*
*Not to exceed manufacturer supported memory.
Although the memory can be installed one module at a time, the best performance comes from using matched pairs of modules.

I would like to upgrade my cpu. Can I put a larger cpu? I have a compaq EVO D510 with a 1.8 processor.

You can upgrade the speed of the CPU. Of course in order to do that you must know the motherboard capabilities. If the motherboard is upgradable to 2.0ghz processor with the same specs with your 1.8ghz processor then you can upgrade. If the motherboard is un-upgradable, my suggestion is to replace the motherboard, get a new processor, memory module, etc. Meaning you just bought a new computer. For the mean time, upgrade your memory module. Un-install the software that you don't need. Especially the one the eats up the processor speed.

How do i change the memory bus speed on my dell optiplex 170l? The CPU is an Intel Celeron 2.4GHz. The mother board processor speed is 400MHz and the Bios indicates a memory bus speed of 266MHz and does...

You checked in the right place as far as looking in the BIOS, however, memory and CPU sockets do not necessarily have the same buss speed. My FSB runs at 1066Mhz and my RAM at 800Mhz, it all depends on what type of RAM you buy as to the bus speed. You can up the bus speed on your RAM if you wish to reduce bottle-necking, but I've only done that a few times. In order to adjust anything, you must set the settings to manual. Be careful when you change this stuff around though, voltages must also be adjusted accordingly.

Tried to add RAM but now computer won't turn on

Didn't we speak online about this a couple of days ago? You can't mix and match RAM. What you added is probably not the right config for that machine. You need to go to this link, plug in your machine information and then REPLACE, NOT ADD TO what you have.
