Sony Vaio UX memory settings

[maloosheck]

I am new on this forum, so please bear with me.

I am in process of upgrading ram in my Sony Vaio UX380N. I was wondering if there is any way to enable BIOS settings regarding DRAM timings.

Shall I attach the bios file here?

Upload or link your bios, I can take a look at it, most likely it won't be possible if the DRAM timing settings are not in the Bios strings_

The file can be found here: http://esupport.sony.com/US/perl/swu-dow...=VGNUX380N&upd_id=3252&os_id=29

If it will not be possible to enable BIOS DRAM timing settings, would it be possible to locate them in BIOS and hard code them? I am particularly interested in tRFC (Row Refresh Cycle Timing).

Thanks so much.

There apparently is no Memory timing settings built into the Bios anywhere that is hidden, to add a new feature into the bios that isn't there to begin with could be possible but that would take a lot of work and apparently is beyond my knowledge. it'll require a lot of hex editing and even then there's still the risk of bricking the bios_

Although I didn't see any Memory timing settings, I did see one that is interesting, there is a setting to adjust the Multiplier on the CPU to raise it or lower it, which is pretty cool, but unless you have an unlock CPU with an unlock multiplier this feature redeems useless to unlock

Well, I am not surprised.

Is there any way to find out if the CPU has an unlocked multiplier? I am actually upgrading a CPU as well and having that option available might be useful as well. I assume that the default is that BIOS uses multiplier set in CPU, right? You have not seen any FSB adjustment setting by any chance?

'Frequency Ratio'
'Select the internal ', 0Dh, 'frequency multiplier ', 0Dh, 'of the CPU'

I found these strings, so I know that you can adjust the frequency multiplier of the CPU,


Now flash with your own risk, I use Pheonix bios Editor to edit it and I enable the Bios Recovery Feature in the Multiboot features_ Which for some reason some Pheonix Bios are disable__

Remove the (MOD) Part of the filename and flash it_ Cross fingers and hope it works =] if it does Enjoy the new feature although like I said, its pretty useless unless you have an unlock multiplier CPU_

Please flash at your own risk, Battery installed and a/c power pluged in and Close all Programs running in background

It was strange that Pheonix Bios editor upon Emulating the Bios you attached, it showed up like that which I thought was odd_ but I was successful in unhiding the Frequency Multiplier Feature in the bios_ I hope it works for you if you do decide to flash it

Most laptops and desktop CPU's are multiplier locked and I don't think there is a laptop CPU that is multiplier unlocked_ use CPU-Z to find out information on your CPU and then Google it to see if its lock or unlocked, altho I highly doubt you will find a Laptop CPU that is mulitplier unlocked

You can use SPDTool version 0.63 to flash your Ram sticks with custom Timings

http://www.techpowerup.com/spdtool/

in that link you should go read the Discussion thread_ now I have to say that only some computers support it, so far every computer I've owned and use this tool on has worked, but there are a few computers that won't support it_

When you flash the Ram sticks sometimes the program will become Un-responsive_ Just leave it be until it completes, I find that its pretty normal_ Its a great tool, risky to use but awesome when successful

I flash my 667mhz Samsung 2gigabyte Ram sticks with my Kingstons 2gigabyte 800mhz Ramstick Profiles and now I have my 667mhz ram running at 800mhz and its been 6+months and stable =] It is a truly wonderful tool to input custom timings also if you don't have the features in the bios_ Now this tool is flashing the ram stick EEPROM so its permanent_

Just use with care and do lots of research on it before going forward, GOOGLE is your friend
