Sony Vaio S Bios Mod For Gt640m Le

[Croak]

RAM size still won't be a serious bottleneck, DDR3 is still an issue, and there's only about 10% OC headroom in the RAM.

Also, if you do ship it back, please don't open it. That way Sony can sell it as new again and not take the hit on the return and have to sell it as a low/no margin refurb for something that wasn't their fault.

So with these insane overclocks could 1GB VRAM become an issue when playing at higher settings and AA due to better FPS, or is the performance at 1600x900 to take advantage of anything over 1gb?

I'm thinking about shipping my order back when I get it and ordering a unit with 2GB VRAM.

Not sure if this can help :


Playing Battlefield 3 at 1600 x 900 default Ultra Settings on Campaign Mode(heavier)

Just incase you were wondering :
The GPU and Memory Load got some white lines due to Alt-Tab while playing the game. Not Throttling or anything.

Amal - Are we making any progress on getting the updated links?

Amal, interesting that your GPUZ looks a lot different than mine. I'm assuming that you're using the 950MHz mod too. At rest, shouldn't those numbers on mine be a lot lower? And some of the other numbers like memory usage don't show up for me either compared to yours.

Here's mine:

So here's something I was thinking about that might be relevant to this mod...

The 640m LE is basically the same core as the 650m--384 shaders but stock core clocks are 500Mhz instead of 850Mhz on a stock 650m (with ddr3). So if I understand correctly, the 950Mhz is pushing this core beyond what even a stock 650m runs.

My W110er (with the 650M) scores 2200 graphics and P2400 in 3Dmark11...Very close to what is being reported here with the 950Mhz mod. Even though folks are saying temps are still safe, albeit somewhat increased, I'm more worried about power consumption with the stock 90 Watt PSU...

For comparison, my W110er with dual core Ivy Bridge + 650M when under full load gets very close to maxing out the Clevo 90 Watt PSU. Some retailers selling quad cores already include a 120 Watt PSU because of this.

Now the Vaio...has a bigger and brighter screen to power, backlit keyboard, etc...If everything else is the same hardware wise (with a higher clocked kepler core) what is to stop the vaio from maxing out its 90 watt psu too?

TL;DR -- Does this mod increase power consumption beyond what the PSU is capable of? Anyone test this yet? I would with my meter, but the bios got taken down.

If that was the case, users would've definitely reported some kinda throttling. However, till date no one has faced any such problems. And anyway, accoding to Notebookcheck.net, S13A consumes a maximum of 60W, therefore, the 90W psu provided should suffice.

Kepler uses memory in smart way up to 2GB of it. It always keeps few MB free and uses the rest of available memory as buffer. The more you have the better. However, even the 1000mhz GK107 is not powerful enough to run max AA and high resolutions in modern games. You should be OK with 1GB version but 2GB can probably offer smoother gaming experience in few situations.
If amount of available memory is getting low, then FPS can occasiolanly drop drastically, because card is needs to dump some buffed info in order to make room for new one. That usually results as splitsecond hickups, which can be very annoyng when playing FPS for example.
Personally i went for 2GB version, since the price difference was worth it imo.

Amal - Are we making any progress on getting the updated links?

Looking good I guess.
MODDER will share the link later.
Will put it up immediately after.

Patience my friend.

Here's mine:

By right it should be like that, and yes I'm using the 950 MOD.
It should drop back to idle clock when doing nothing.
The Load numbers only show up when you use actually use it.

For example, if you open up 3DMark11 without running the benchmark yet, the clock will stays at the full clock, but the load will be 0%, and temp wont increase much.
Once you run the Benchmark, the usage/load will definitely goes up, and temp will start to increase.

Good point there.
Never thought about the limitation of the PSU.
Don't have the tools to test it out though.

Basically why you are seeing a similar scores to yours is because of the Boost features.
Currently the Boost features seems to be locked by something on the VAIO S GT640M LE.
Cores also won't budge above the basic clock, eventhough you OC it. GPU-Z might shows that it increased on the info, but sensors will show it as 950MHz max instead of the new OC clock.

As for your GT650M DDR3, your base clock is 835MHz, but your boost clock can go up to 950MHz.
Usually when you run benchmark, it will boost to 950MHz.
That is why we are seeing the same scores here.

I think that the answer of my question is evident, but did this mod modify the consumption of the 640M? Or is it the same? It seems that the modder don't touch the voltage, so I suppose that there is no difference?

If that was the case, users would've definitely reported some kinda throttling. However, till date no one has faced any such problems. And anyway, accoding to Notebookcheck.net, S13A consumes a maximum of 60W, therefore, the 90W psu provided should suffice.

No link beetween throttling and power consumption, the laptop will take the power on the battery.
This is the case with the MBP retina, the consumption is 92 watt and the power dapter is 85.... and nobody speak abot that problem which is a shame on a laptop at 2300€.
Old MBP 2011 with 6750M and 6770 was affected.
