BIOS check stops at "checking NVRAM"

My PC has just developed the above. I've tried reseating the RAM (2 x 512 DDR 266), but haven't yet tried replacing the CMOS battery. Will this solve the prob lem? or is there another fix?

BIOS NVRAM checking - not passed

I have had even new sticks of ram not work in one machine, but are fine in another. Put the old ram back in and make sure everything works like you want, then try the ram again. If they are still giving problems, unfortunately it looks like even more ram is your solution.

The ram slots on my ga-81865gm-775-rh-as MB are reporting my ram chips as 512k each rather than 1g each. The chips are 400mhz, supported, Kingston kvr400x643ak2/1g. I've already removed the ram and...

Hi, you can download a manual here:

Your mainboard supports:

Type: Dual Channel DDR 400 / 333 / 266 support
  1. Max capacity: 2 GB
  2. DIMM slots: 2
* Due to standard PC architecture, a certain amount of memory is reserved for system usage and therefore the actual memory size is less than the stated amount.

Its maybe a setting in the bios or you missing a driver that causes the problem.
Or one of you ram modules is defect.

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.

I want to extend the RAM memory on my NEC computer. The motherboard is a GA-8SIMLNF Rev.1.1. It has two memory slots and presently one slot is occupied with a PC2100U-20330-A1 256 DDR 133 CL2 memory. I...

Check your manual (Gigabyte will have the manual on their website), to make sure your motherboard can handle 1Gb of Ram, or more. Generally in my experience, medium aged motherboards handle 1GB per slot, max (mine uses PC3200, not PC2100, and will take up to 4GB in its 4 slots).

You'll want PC2100 ram (easily searched for on, either in 2x512MB sticks, or a single 1GB stick for your open slots (bringing you up to 1.25GB).

Hey Richard, your board has 2 x 184 DIMM slots, that are both usable, with a maximum capacity of 2GB, supported RAM types are 333MHz, and 266MHz..

Hope this is what you are looking for,

DDR 266 is DDR, not DDR 2 . The 266 is the frequency value in Mhz.

Try having the memory refunded or resell it on Ebay, so that you do not lose your money.

Here is supported memory, many older motherboards do not accept modules of over 512Mb each, ask to the seller:

I can't recognize what specific RAM this motherboard accepts..

Dear sir,

In reply to your post- Generally now a days we use DDR400 RAM(DDR 1) for this type of motherboard.So DDR 400 RAM is More compatible then other RAM,you can use this RAM for your motherboard to obtain good performance.

good luck

The front side bus speed of the processor is the limiting factor of your RAM speed.
The Processor has a 400 Mhz FSB, hnece your RAM runs at 266.
For RAM to run at 333 (PC 2700), you'll need a 533 FSB Processor.
