Why it doesn't use the RAM memory?

October 22, 2016 at 08:58:48
Specs: Windows 7, Intel Core 2 Duo E6550 2.33GHz / 1 GB Ram :/
I recently bought 2 x 2GB RAM DDR2 PC2-5300 / U667MHZ DIMM memory and when i inserted (booth of them) into my pc, it didn't started (black screen, no beep ...) i removed one of them and the same, and then i added one of the old one(512 mb, ddr2 sdram) along with one of the now one. it started, opened windows and into system info says that it has 2 GB installed and only 512 mb usable.
In the BIOS says that into DIMM1 it's 512 Mb and DIMM2 2048 Mb of RAM.
I updated the bios from ver 5.22 to ver 5.31

The motherboard it's MSI ms-7525 ver 1.0

Are you sure you have bought RAM compatible with the motherboard?

Perhaps go to:

crucial.com

and run their memory scan util. It's free, safe to use - and will tell you exactly what the specifications are re' RAM. You download a wee small file, and the scan then runs...

It will also advise on any other upgrades that you "could" apply re' RAM and hard drives...

You don't have to buy RAM from Crucial - often the same chips can be found (for example) on Amazon at lower prices; but not always.

"The motherboard it's MSI ms-7525 ver 1.0"

Apparently it's an HP board. It's unusual that it didn't beep when the RAM was installed. Try cleaning the contact edges of the RAM with a pencil eraser, then wipe with alcohol or acetone. Make sure the system is unplugged, lay the tower on it's side, then snap the RAM in/out of the sockets a few times to make sure it's making good contact. Then try booting up again. If you're running Win7 32-bit & using the onboard graphics, don't be surprised if the memory amount in Windows is 3GB+/-.

The motherboard see them both, but only one by one(only 2 dimms available) along with a old one. Into BIOS it says that it is installed 2,5 GB

I'm not 100% sure, but when I bought I've checked for it and on specifications was " DDR2 PC2-5300" too.. soo, what can be wrong?

And one more thing... On the new RAM units it's no label. The specs that I've said are from the EBay site.
It could be unsupported by the motherboard, but what BIOS says it's still non-sense

As I suggested above - run the crucial.com scanner to confirm exactly whic RAM is suitable?

Also do you get same effect (only finds 2.5gig installed) with each new (a single) stick installed with the 512?

Yes, only 2,5gb... but only in bios it shows this way
Into system info says 2gb with 512 usable

I've scanned on crucial.com and there it shows the 2 GB into one slot and the 512 MB into the other one

Did you look at crucial's recommendations for which types and size(s) or RAM are viable/compatible... It's one of the reasons (if not the reason) for running the scan utility. The results are on the righthand side of the page after the scan. There will be RAM information, and probably hard drive upgrades it suggests.

I took a look there and the specifications was the same as what I got.

You may need to manually set RAM settings in BIOS to make them work properly.
Pay attention to Speed, the secondary numbers like Latency, and the voltage (often overlooked). Sometimes the machine may be setting it to the default voltages and the memory may need a slightly higher settings. For example, your original memory may have needed 1.5Volt and the new memory may need 1.65Volt. With one stick at that voltage it may be getting enough for in BIOS to operate but not fully in Windows but with two sticks, it may not be getting enough to each stick to start up. It may be that the BIOS is running off your older stick and reporting on the newer stick but ignoring it as non-functional. Set settings for new RAM, save and exit but shut down before Windows starts, then swap both new sticks in and see if that works.

The bios is so poor that got only few options. It cannot overclock anything, cannot set any voltage or fervency. Only the main options there and that's all.

Even on limited BIOS as on factory machines (HP, Dell, etc), there still should be RAM settings available. One all memory there is a sticker that will tell you the optimal settings for it including the speed, the voltage, the secondary numbers including Latency, etc.

I Googled your motherboard manual and many of the hits include HP/Compaq like this one:
http://support.hp.com/us-en/documen...
You can search for the manual for your system specifically and it should show you BIOS options. That and the Crucial scanner as mentioned should help you. The above link does show that you can use faster memory.

Hello guys.. I got back with even more trouble.. I've changed the motherboard and still doesn't work. I got an Intel dq35jo now. But that's not all. I tried with the old RAM and worked... Until I had the bad idea to set the wrong memory settings in BIOS. I set 800 instead of 600 and now it don't start anymore ... It beeps 3 times ... And this mean that it doesn't see the memory. After that I've tried the same non working memory in the old motherboard and it worked there

... Bad idea..I know

Use jumper to reset the BIOS to factory defaults, then go in and set time, date, memory, hard drive and boot options, PCIe/graphics is used, etc. Save and Exit.
If you were looking got more BIOS options, Intel boards were not the best option. If your memory has XMP option, then set BIOS to use that option since it will use settings stored on the memory to configure the optimal settings. Otherwise use the listed specs on the small label on the memory itself (copy specs or take pic with phone and zoom into it).
