I just got my S460 and they came out with the s560, then the SZ. What’s really getting me is that the S460 only runs the ram at ddr400 instead of 533… but the cpu bus is 533. after checking with intel, I see the chipset does support DDR 533. (Heck the laptop came with ddr533, and I upgraded to a gigabyte of 533)

And looking at the sony bios… there isn’t really any option for memory speed. Now it seems like the s560 is a cosmetic upgrade with a slightly better video card and ddr 533 memory.

I know people have managed to hack/flash TR3 bios onto TR2. I was wondering if it was possible to do the same on the S460 by flashing on the s560 bios… That might enable the ddr 533.

Hi there,
you dont need a bios upgrade for this. just make sure that both ram modules are 533mhz ones, if you mix 400 and 533mhz then both will run at 400mhz speed. in case you play alot of graphic intensive games i suggest to put in two equal modules (2x512mb 533mhz) so they run in dualchannel modus. This way the accesses from the graphic card to system memory when more than 32MB is needed will not slow down the overall traffic to the cpu.

there are some fixes around in the internet so you can get the S5-Bios on S3 and S4 models, but i would not recommend them. the bios update was mainly done due to thermal issues. The S5 has a new designed fan and the fan on/off settings and fanspeed is different. you will probably end up with a constantly running and louder fan…
