what is the make and model of the memory?

what happens when you only insert one 2GB memory stick?

desouza420 · Apr 10, 2015

Manufacturer : Kingston
Type : DDR2-SDRAM PC2-6400 (399Mhz)
Size : 2048 MB (1 ranks, 8 bank

i used to have 1 x2GB DDR2 and it was working correctly
but after i bought 2x2GB DDR2 and im having this reservation from my hardware

No it isn't "reserving" memory, your just using it all up with everything you 'load' all the time on boot.
Use a simple tool like AUTORUNS.exe to turn off all the extra stuff loading, but you still will normally eat up 1-2GB just loading the OS, Antivirus, etc. Your real solution would be to go 8GB if you need more RAM on your system, but considering the very old age *DDR2) it isnt' worth the investment, as this system is way past it's performance > cost ratio.

yes but this shouldnt happened

Yeah it WOULD as you have ONBOARD Video http://www.gigabyte.com/products/product-page.aspx?pid=3485#ov
Which takes a portion of your RAM and puts it to the GPU onboard to use. If you mistakenly set it in BIOS you could have up to 2GB or can be (per the Mobo Manual) also a default that you can't get around (thus need more RAM as I mentioned).

Again though, this is a OLD DDR2, so it isn't even worth the matter of cost VS performance when a new system with the same amount of money put into it would be more performance for the same sort of costs.

ive just disabled on board VGA because i use another graphics card
but nothing has changed still the 2GB RAM is reserved by hardware

Already looked at msconfig->tab boot-> advanced options and see if max. mem. is unchecked?

Tom Tancredi · Apr 11, 2015

Well how did you disable the video? in Windows? Wont' matter, I was speaking in BIOS. Which is also where you can set the amount of RAM to be 'shared' to the GPU (aka dedicated).

desouza420 :

Did you add 1x2gb or bought a new set?

Don't think the memory controller can adress more than 256mb to the onboard vid. so 2gb is way to much imo to be hardware reserved.

desouza420 · Apr 11, 2015

Vic 40 :

it was unchecked

desouza420 · Apr 11, 2015

Tom Tancredi :

ive disable it from the BIOS

desouza420 · Apr 11, 2015

Vic 40 :

I bought a new set of 2x : DDR2-SDRAM PC2-6400 (399Mhz)

Tried bumping the Vram to 1,9V?

desouza420 · Apr 11, 2015

how can i do that?

Vic 40 · Apr 11, 2015

You should go to "MIT" in the bios then look at " DDR2 OverVoltage Control" and it allows you to set memory voltage.

Normal Supplies the memory voltage as required. (Default)
+0.1V ~ +0.4V Increases memory voltage by 0.1V to 0.4V at 0.1V increment.
Note: Increasing memory voltage may result in damage to the memory.

So set it to +1 and save with F10+Y.
I did put the warning there,but +1 should normally be fine.

desouza420 · Apr 11, 2015

Vic 40 :

i just did that but i havent notice any difference

Vic 40 · Apr 12, 2015

You could go for +2 and see if it does.Other wise is there probably no point and could you revert to the stock settings.
Tried one stick at a time as suggested?
