Bios reports incorrect memory speed

MF750-- Have installed 4 512 PNY Gamer memory chips @800. When booting up the machine, the ram shows up as 677. I have already tried flashing the bios to the latest version, but to no avail. Forcing the ram into 800 via the bios config does nothing either, except cause the amount and speed of the ram to show up in bold white on boot up.

Thanks for any help

    Yes all memory mods are 800.

    KriHard, What do youmean setup new bios? I have already flashed it and tried removing the battery, not avail, then reflashed again, but still same problem.

    Maybe a better question is, will by bios reporting the speed as 677 limit the memory to that speed, or wil it run as 800 regardless?

    BTw, I incorrectly stated the motherboard. It is a epox mf570, not a 750

  • mrc420 Jan 26, 2008

    AS I stated earlier, I already flashed the bios to the latest version.

    On your advice, I tried using only one stick, but the bios still reports it as 677.

    All Indications on the motherboard manual say it does support 800.

    I also have tried contacting Epox, but thier technical support dept. stated they are closed.

    Thanks for trying cosisf!

I have the same MoBo that you speak of. Have you overclocked any portion of the settings under the advanced tab where you found the memory speed? Overclocking affects all aspects of the system. You may want to download CPUZ and check the settings from there. Also, you should download NVIDIA's Performance Control Panel so that you can control the speeds of your system more easily. Good luck,

Try to update the BIOS ! ... it may correct the problem ...

when using only one module at a time, doest it work on the correct speed 800Mhz ?!

the system will be working on the BIOS declared parameters, at 677 !

Also read all the indications in the motherboard user manual, regarding memory (supported brands, speed, slot allocation .... )

thought i hope the BIOS update will do the trick ...tell me if it worked ...

I upgraded my gategay gt-5428 computer memory 1 gb to 2 gb but still runs with i gb, what i did wrong?

Hello Erik,

Are you absolutely certain that the new module is compatible with your system? Go into the BIOS and see if it is recognized there.

Crucial shows that your computer takes DDR2 memory with support for DDR2 PC2-5300, DDR2 PC2-6400 speeds.

Make sure it is not ECC memory. ECC is not compatible.

If you are sure of the compatibility, I would try to install the old one by itself first and make sure the system boots. Then I would remove the old one and install the new one by itself. Try booting. If it doesn't work, you may have gotten a bad module. (It happens.)

Just FYI, here is the crucial link for your computer:

Thanks for using Fixya.

Tried to upgrade ram with 2 new pc133 sticks of 256mb ea. Didn't work. What's wrong? Are there switches on the motherboard I need to change? Or something else?

No there are no DIP switches to change, or jumpers to move on your motherboard, in regards to your BIOS recognizing ram memory installed.
(BIOS. Basic Input/Output System. This tiny program, {64MB in size usually}, that is burned into your BIOS chipset, is what recognizes ram memory on your computer)

Things to know about the older Sdram ram memory.
1.It's really SDR Sdram. Single Data Rate Synchronous Dynamic Random Access Memory.
DDR is Double Data Rate Sdram, DDR2 is Double Data Rate 2 Sdram, and so on.

Point? All ram from SDR to DDR3, IS Sdram.

2.Standards have been set by JEDEC for computer ram memory starting from DDR Sdram on up. This standards were not implemented back in the day of SDR Sdram.

Point? Ram memory manufacturers didn't all follow the same standard, and ram memory made for one computer, would Not work in another computer.
This means you need THE ram memory for YOUR eMachines computer.

Main factors when buying SDR Sdram,
A.Correct type. You know this. SDR Sdram.
168 gold plated contact pins on the bottom of the ram 'stick'. (82 on each side)

B.Correct 'Speed'. ('Speed' is slang for Frequency Rate) You know this. SDR Sdram that operates at a frequency rate of 133MHz. (Or also known as PC133)

C.It must be low density Non-ECC ram memory. It cannot be high density ECC. (Error Control Correcting. Used for Server computers mostly)

D.Correct CAS Latency. Also known as Ram Timings. 3-3-3-3-2 would be normal for SDR Sdram.

E.Correct Chip Configuration. How the DRAM chips are accessed. DRAM chips are the black rectangular chips on each side of your ram memory 'stick'. Also what size the DRAM chips are in MegaBytes. (MB)

F.What the Maximum TOTAL Amount is for the motherboard. Is it 256MB? 512MB? Or more?

G.What the Maximum Amount is for EACH ram 'slot'. (Correct speak for 'Slot' is Bank)

H.Do you have four ram 'slots'? You MUST have a ram stick in Slot 1. This is the slot closest to the processor. It is the first ram slot the processor 'reads'.

Install the RAM on memory slot and Switch on your system and go to BIOS settings. There you can check whether your RAM is working properly or not. If it shows no memory installed then the RAM Chip may be damaged.

Memory Useage Concern

That memory amount does not sound correct - it might be the free memory count. What does it say when you go to CONTROL PANEL -> SYSTEM? If it has a low memory count, try this.

When the machine reboots, press the delete key or F10 key to enter the BIOS and have a look at how much memory the BIOS is reporting. If it seems incorrect, you may have mismatched memory (so only one of two chips is working), or one of the chips may have become unseated in its bay. Turn the machine over and unscrew the memory bay door and reseat the chip(s) if necessary. If you reseat them and the memory reported is still incorrect, you might have faulty memory. Actually, faulty memory chips have become extremely rare.

As a last resort download SISOFT SANDA LITE for free on the web (or from and then run its memory test tools. Laptop memory is very cheap right now, so you might consider replacing if it has become faulty.

Good luck...

Memory Recognition

The BIOS recognizes the same speed chip. Say, "PNY 512mb 333mhz 12ns". If you mix and mismatch, the BIOS won't see it even though your motherboard will take the differant type chips. They should all be the same.

Ram Memory

your motherboard my only recognise two of the same size or make of ram. try the 1024mb in on it's own and see if the bios allows the system to boot and recognise it. see what windows recognises, go to my computer, right click, properties and in the main window it will tell you processor speed and look to see how much ram is showing
