it's real SSD and you can de-activate expresscache completely (to have that ~20gb free for temp dir, etc.)

sellitus + andy... could you share screenshot of device manager / disk drives section?

what makes you think it's faulty? default configuration (with HDD+SSD) is that expresscache dedicates ngff ssd for caching and therefore ssd drive is not visible in windows explorer. You can check if expresscache is operational by admin cmd line eccmd -info

mibix... you were dropping the batch file to patcher, you need to drop actual BIOS file to patcher, and then re-flash the patched file back

xizorkun... i have slv7's bios and SLI working nicely under w8.1

i have automatic switching... (little notification shows that i have plugged in headphones, etc) my audio driver version is 6.0.1.7083 (oem preinstall updated to w8.1)

toxic.. are you running 8.1 with 32 bits or 64 bits?

hmmm... expresscache works very nicely... after few hours of usage it will get up to 70% read hit-rate and using system is almost as fast as with pure SSD. The caveats are that expresscache is poor in write caching (it seems to be write-through cache, rather than write-back, which is safer, but a lot slower in write-intensive applications). You can even instruct expresscache to pre-read directories with eccmd command line (see google for "eccmd command line" to get help how to create/tune it) so I would say if you don't have full SSD, expresscache is well worth it!

any info about differences compared to 1.xx or 2.xx versions?

btw. if you upgrade 2.5" ssd and copy partition you may want to get rid of xpresscache and use msata as temp drive

i currently running kingston ssd v+ 120gb but i'll move to samsung evo 840 1tb; it has basically best value (capacity and speed) for money, with usb kit, it costs around $550 in amazon (i moved previous hdd to external and did part copy with Macrium reflect, which is free)

Is there a list of confirmed (i.e. non-bricking) tunable options in unlocked bios? -j
