NP9262 RAM Chip Manufacturer

To anyone who has upgraded their RAM in the NP9262 to 4 gigs after-market, could you please post the Manufacturer of your chips? I recently purchased OCZ 2 x 2 gig chips of DDR2-800 to upgrade from 2 gigs to 4, and they just don't work (cause extreme graphic anomalies). They also result in the same anomalies when used in my AW m9750 with SLi, so I think there's something wrong with the chips (although they pass a memtest).

I think OCZ chips just may not be good. I'm curious what other people have had success with (e.g. Transcend, Crucial, pqi, etc).

Thanks.

 

It does not really matter about which brand.

Most memory has a lifetime warranty, and also has the same memory chips.

 

How many sets of OCZ RAM have you tested? Perhaps you just got the 1 bad apple in an otherwise perfectly good orchard of apple trees?

 

Volker also bought 2x2GB.he should have it tomorrow.

Ther's another guy who wrote in forum that these were the best.

 

He wrote that the OCZ were the best?

 

Yep,get them replaced, OCZ works , I`ve seen people having 9262s in their sigs with OCZ 4GB 800Mhz RAM.

 

Dumb question. Have you tried one at a time and mixed with original to try and identify if one of the new sticks is the issue and not both? As that would depending on the outcome with no more information (if neither works alone) than before. Or that it is not the brand just a bad stick?

 

He did say that they past the Memtest mem test .. pun intended

 

I did another memtest last night, this time in another laptop, and the chips passed again.

I have a theory:

using a 32-bit OS, you can't get the system to work with 4 GB of RAM unless you have that 4 gigs installed when you do a clean install of the entire OS. If you clean install with 2 gigs and then change to 4 gigs, it causes issues (this is my case).

Also, if you do have a NP9262 and a 32-bit OS, doesn't it only address 2.8 gigs of RAM anyway? So I'm only missing out on 800 megs, not a catastrophic loss...

 

Yes,Kind of.

yes 32 bit Vista will only 'see' the 3.5gigs before SP1 and with SP1 it will 'show' the full 4 but it will still only use 3.5. I read that they did this because of newies calling support saying their computers were not showing all the ram

 

I started with a 2gb [Super Talent T800SB1G's] Laptop last June and several months ago I replaced with two sticks of OCZ2M8002's. Runs WinXP without problems.

Recently [within the last month] Sager upgraded m/b with same sticks installed...

 

I have OCZ 2x2 gig installed for about 4 months now and haven't had any issues with them in my N9262.

 

Ok, you have a proposition; now what's the theory that supports it? I have a system (old vaio) that originally came with 512MB - 256MB fixed/256MB replaceable - when the OS was originally installed (factory pre-install). I upgraded the replaceable unit to 512MB, for a total combined RAM of 768MB, without reinstalling the OS and without any noticeable effects (other than that certain things ran a little faster afterwards ). As anecdotal evidence, that would tend to contradict your proposition, so a theory behind your proposition that is capable of explaining both your problems and my lack thereof is necessary.

Alternatively, we can just apply Occam's Razor and conclude that the most likely problem is with the memory itself - are your sure that the memory in question is the appropriate memory for your system, in terms of timings and latency? Also, while memtest is good, it cannot take the place of the ultimate diagnostic - trying completely different 2GB sticks in there to see if the same error occurs.

Lastly, what CPU are you running? If I remember correctly, there were some issues with the Q9450 and Q9550 being able to handle 4GB of RAM in the D901C initially - perhaps the problem you're experiencing is related to whatever that problem was (it's obviously been solved since Sager is now offering the Q9x50's in the NP9262).
