RAM Upgrade I have an IBM 8122 model system ! it has P4, 3.06 Mhz & 915G chipset ! I contacted lenovo support and they said it supports 400Mhz FSB RAM only ! While on contacting local retailers, they say it supports DDR 400, DDR2 400 and DDR2 553 fsb RAM. the DDR2 400Mhz one is only available at lenovo support. costs 4000 bucks for 2GB while the DDR2 553 MHz is available everywhere at just 1200 bucks ! what should i do ? lenovo support says that it wont work properly with 553MHz while retailers say it supports 553. what to do ? what should i purchase ?

    thanx but i got 533 Mhz FSB 2x1GB RAMS.

    what you said is incorrect.
    Intel 915G motherboard supports both DDR and DDR2 and its the only motherboard that has this feature.

    nope...it has that divider in the mioddle.

    as DDR and DDR2 both have a divider in the middle.
    i searched google for the exact difference in looks !



    but in my board, both are supported.
    it came fitted with DDR 333 Mhz fsb. Worked gud
    Now i put 2x1GB DDR2 533 MHz fsb. It works gr8 !
    and both had different slots as shown above.

    maybe the key hole in my board is a bit large that supports both !

    even i cant make out as all 4 slots look the same !

Let them install it for you. Go for DDR2 667. If it works, gret, if it doesn't scale down... But DDR2, and DDR 400 aren't nearly the same, they won't fit onto the same system, as their pin configs are different.

If the DDR2 doesn't fit, you'll have to go for the more expensive DDR 400.

    Ok... interesting indeed. :) i stand corrected. I am curious as to how these RAM slots look. I'm guessing it doesn't have the normal divider on the board itself somewhere in the middle of the ram slot?

    :::goes to google with a curiosity twinkle in my eye:::

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),

http://support.dell.com/support/edocs/systems/dim2350/specs.htm#1101572

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

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Pentium_4_chipsets

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

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_4_microprocessors#Prescott_.2890.C2.A0nm.29_2

(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)

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

http://en.wikipedia.org/wiki/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)
IDE (PATA)
SATA
USB
Ethernet
Audio (Sound)

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

[ 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.

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)

Hey All, THIS IS URGENT. My PVCLE266M-L V3.0a will not boot into any OS. I have 2 identical boards. I can navigate BIOS on both of them with the DDR400 512MB RAM stick I have put in. (The specifications...


Your mainboard PVCLE266M-L does not support the DDR 400 Mhz RAM (PC3200) ie @ 400Mhz frequency. For the memory specfications it support "2 x 184-pin DIMM sockets support two2.5V DDR SDRAMs (DDR266)" maximium is 2GB or DDR PC2100 ie @ 266Mhz frequency.

PC133 is the SDRAM so it will not fit the DDR RAM slot.

You should not use the 400MhzDDR memory RAM on a Mainboard with a FSB(Front Side Bus) of 133 Mhz and the 400Mhz DDR Ram is not compatible with the mainboard.

Get the DDR 266 with double side chipset i.e.DDR1 RAM (DDR PC2100) RAM and it will be compatible with your mainboard. Sometimes single side chipset DDR1 RAM will not work on older mainboard.

Hope it helps.

No, u can't. ur motherboard is designed for pentium III processors with FSB -133 MHz, Socket-370 type. Pentium 4 processors have 400 MHz FSB, 423 Socket at least. But yes for memory, u can upgrade it to 512 MB.

Can I upgrade my CPU to an Intel Core 2 duo 1.7


You are basically limited to what was optional on the model. So you can only upgrade to one of the following cpus:

Intel Pentium M 745 (1.8-GHz) with 400-MHz front
side bus (FSB)
Intel Pentium M 735 (1.7-GHz) with 400-MHz FSB
Intel Pentium M 725 (1.6-GHz) with 400-MHz FSB
Intel Pentium M 710 TJ85 (1.4-GHz) with 400-MHz FSB;
operates at a lower temperature than other processors
Intel Celeron M 340 (1.5-GHz) with 400-MHz FSB
Intel Celeron M 330 (1.4-GHz) with 400-MHz FSB

And you are limted to 2gb of ram max on this model.

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.

According to SiS® official document, SiS® 748 chipset has limitation DDR supports:
CPU at FSB 200MHz mode, it will NOT support DDR400
CPU at FSB 333MHz mode, it will NOT support DDR200
CPU at FSB 400MHz mode, it will NOT support DDR200/DDR266

Depends on chipset http://www.asrock.com/mb/overview.asp?Model=K7S8XE

Upgrading Processor & Graphics card


The Intel® 845G chipset is optimized for the Intel® Pentium® 4 processor supporting Hyper-Threading (HT) Technology†. It is designed with the high performance 533/400 MHz system bus and integrated high-speed USB 2.0.

Max Cpu
Pentium 4 2.8ghz with a 400mhz FSB and
Pentium 4 2.63ghz with a 533mhz fsb

pay close attention when getting your cpu if it has a 533 front side bus and is faster than 2.63 then the actual cpu speed will end up slower (you will see something like 2.1ghz) if it comes on due to multiplier limitations
