Recently I pulled my old Acer Aspire E560 out from the heap of junk in my attic and decided to see what I could do with it.
I replaced the anemic Pentium D 915 CPU with an Intel Core 2 duo e6400, put in a Geforce 9800GTX+ (way OTT together with the intel Core 2 duo, I know, but it was a leftover from an other project), 2 x 2GB kingston RAM, and a random 550 W PSU I had lying around.
Finalized it with a fresh windows 7 64bit install......and.....it moves! At least a lot more than before Benchmark scores from Novabench shows a total score of 561 for the system after upgrade versus 229 before. (The 2 x 2Gb RAM modules were in on the pre-upgrade test as well)
Now it was time to squeeze some extra juice out of it, hence I checked in at overclockers.com
However, to my understanding....now, the BIOS, AMI R01-B1 04/02/2007 does not allow for overclocking. This is the most recent BIOS version I could find on Acer support.
Now my questions.
1 Is there a way to overclock that does not rely on a cooperative BIOS?
2 Would there be any way that I could "unlock" the BIOS?
3 The BIOS, and then of course WIN 7, does not see any more than 3 out of 4Gb RAM. CPU-Z detects all 4Gb. I have tried to clear CMOS, switch around the RAM modules, all to no avail. Any Ideas on what to do to make all 4 Gb visible and available?
