Another Sony Z 8gb Question

Hey Guys

I have been reading through tons of posts about 8gb on the Z. Mine is a VGN-Z555DN. I am using bios R2170M3. I have no problem switching bios if need be. The ram I am looking at is this Newegg.ca - G.SKILL 8GB (2 x 4GB) 204-Pin DDR3 SO-DIMM DDR3 1066 (PC3 8500) Laptop Memory Model F3-8500CL7D-8GBSQ

Just wanting to make sure this will work and what Bios would be best.

Thanks for all your help

 

Nobody...I ordered the ram so I hope it works. Can anybody tell me what the best BIOS wound be

 

R5031M3 or R4044M3

 

Thanks NHT

 

Old Z-5xx? No, do NOT install R4* BIOS. Stay with R2*
Either 2169 or 2171, depending on what you want/need.

R2169: Allows EFI boot, and thus ability to turn on the "Advanced" menu in the BIOS. Does not work with Windows 7 nVidia graphics.
R2171: Disallows EFI boot, exposes one of the two VT options from the Advanced menu to the user, allows Windows 7 nVidia graphics.

 

If I install the 5 series of BIOS will my machine not work properly? Will the R2171 work with 8gb of ram? I read through this post and it looks like this BIOS will not work with 8GB http://forum.notebookreview.com/sony/480610-sony-vaio-z-vgn-591u-w-8gb-ram-2.html.

 

No, the reason why that wasn't working wasn't the BIOS version, but because it was SODIMMs with 8 chips per side -- only ones with 4 chips per side will work.

If you read a few post more in the thread you posted, you'll see that 8 GB ram does indeed work with R2171M3.

As for why you shouldn't go to a newer BIOS is because all you achieve that way is adding hardware support for hardware you don't have. But the expanded BIOS versions also have more problems with the ACPI tables. The main symptom is inability to suspend from Linux, or having to replug devices after resuming in Windows.

(And whatever you do, don't install a second generation BIOS, because in those, 8 GB RAM support has been disabled. First and third generation are the only ones that allow 8 GB RAM.)

 

Crap, I ordered ram with 8 chips per side. Has anybody got this ram working on there Z? I can send the stuff I have back when I get it, but it would be easier if this just worked.
