Having trouble installing a piece of hardware? Want to know if that peripheral is compatible with Linux?

But the offcial site of RAM says that RAM is working on 4/5/6 latency. Wouldn't that mean it should work? And why it says DDR665 and 332 Mhz and not 667 Mhz and DDR2 as dmedicode output?
I have submited the problem to ASUS and they will respond in 48 hours.
Yes, it should work, but I think the BIOS doesn't support it, so that's why it doesn't work. It could work, but the BIOS is getting in the way. That's not to say that a new BIOS would fix it, that depends on how much they care for supporting other RAM.
I downloaded UBCD and on USB i saved bios file and aflash2.exe (this file i have on my original DVD when i bought omputer). I went to freedos (by UBCD) and updated BIOS to latest 218 version. I inserted my new RAM and BIOS still doesn't recognize it. So, i will have to switch for another one, this time for CAS 5 and 667 Mhz.
Thank you both for such a generous and exhastive help. I will report my progress in following days.
I have bought a new RAM from Kingston and this didn't work either. Specifications:
I have tried module with old and new BIOS and nothing worked. I think that the problem is in my computer. I give up.
Official Kingston site suggests i should use module with 800 Mhz C6 (i found this info later on when i already bought the other module) but i doubt this would work because dmidecode shows i run RAM on 667 Mhz and memtest tells i have C5. ASUS support in Slovenia suggest i should use the module Kingston suggests.
Maybe i will buy it in the future but right now i am really pissed
I suggest that you have put in enough of the hard yards,
take the unit to a reputable PC shop and stand there
and let them do the upgrade. I think that the extra
fee would be worth it now.
I recall a @$%@#@%@$'ard of a Compaq laptop doing
exactly the same thing. In the end I had to get
genuine HP/Compaq memory to make it work
(by luck coincidence a mate at a local PC repair
shop sold me a handful of modules for a song,
and there were two of them; BUT not after I
cumulatively spent a lot of time mucking about).
In that case it wouldn't accept DDR SODIMS that
were faster, or higher latency.
One day i will take my computer to some company to arrange correct module. But i just don't get it why the bought module didn't work because it had correct Mhz and latency. Well, that's why proffesionals are proffesionals and enthusiasts are enthusiasts
I wanted to do it by myself because i really like to "experiment" with my computer and i am really low in cash (damn recession
It has nothing to do with professionals or enthusiasts. It has to do with the BIOS supporting individual RAM sticks.
Here's a strange example with a laptop of mine. It is laptops that mostly have the issues, but they can sometimes occur on desktops. One of my two RAM sticks on a laptop died, so I bought 2 new ones thinking I would replace both because the other one might fail very soon. When I replaced both, to my huge surprise, the laptop didn't boot. Here's some combinations that I tried:
slot1 + slot2
1 new + 1 old = boot
1 old + 1 new = boot
1 old + none = boot
none + 1 old = boot
1 new + none = no boot !
none + 1 new = no boot !
1 new + 1 new = no boot !
I cannot explain this in any way, except that the BIOS is f'd. It is the latest BIOS available.
Strange indeed. Years ago i have changed RAM on my desktop computer and all went fine. So i concluded that changing RAM on laptop would be peace of cake. My a**. Shouldn't BIOS developers take more care developing BIOS and releasing more BIOS updates?
So, did you find solution for your laptop? When did you bought those RAM modules?
I bought the modules from a store, but the laptop is old and the BIOS was released long ago, maybe that's the problem. There was no solution, the laptop is too old and the HDD also is failing and it will not detect a new one that I bought, likely another BIOS issue. Maybe the best thing to look for in a laptop is if the BIOS is updated for supporting new hardware.
