PQI ram?....or MoBO?

[alexsabree]

Basically i have had nothing with problems with my ram.

I wonder if its my ABIT AS8-V MoBo?? heh, think not


I have one stick of 512mb ram from PQI
And a stick of 256mb ram from PQI

(Shouldnt they be compatable?)


1st time i booted up my mobo:
256mb in slot 1
512mb in slot 2
(It didnt work)

Then i switched teh two......
(Still didnt work)

Then i put:
512 in slot 1
256 in slot 3 -WHICH IS IN DUAL CHANNEL-
(GUESS WAT, IT WORKED, BUT IT FROZE WHENEVER I HAD TO USE MORE THAN 512 mb RAM)

Somewhere inbetween i found the right place to put the ram and it only showed 512 mb... and it didnt freeze or anything. Then a couple days later it didnt work)


Wat is going on?...


The only answers i have is that maybe the 512mb ram is dead, becuase the 256mb works perfectly when its alone
(Thats wat im using right now)

BTW: i have a very nice mobo. so i could try to add more power to the ddr slots. That might b it, right?

Sounds like the RAM is your issue. Personally, i would not try to up the voltage on the DDR slots.

Buy some Quality RAM and you won't be disappointed.

RAM is so cheap these days it crazy.

Run memtest86 from http://www.memtest86.com/ using one stick in your motherboard at a time.

That will determine if it is your RAM that is faulty, and which stick, if any.

My guess is that your motherboard isn't appreciating the mixmatch of RAM. I say either get all new RAM, or get a matching stick, if you find no problems when running memtest.

.. well i can only run memtest on 256.. and that seems to work fine by itself.

I also was trying to get another pair of 256, but they changed it. I cant find my model any where. Will it not work right if i get the same brand but different model?

BTW: My model is 256mb PQI #MD4456UOE


And dont worry about my 512.. i think its just broken, cause it wont work in my friends build.
