What will happen if i change memory voltage to 1.5v when their suppose to be 1.65v? loss of peformance?

anyway, i just recieved my new ram, its 1.65v memory, will this work fine in my mobo? doesn't say in manual :S ram i'm using now is 1.5v, so could someone let me know, and also tell me the difference of a 1.5v memory and 1.65v memory. Thanks
Yep, if you didn't reinstall, Windows wouldn't work, or it would bluescreen, or if the platform was that similar that it actually booted, it would only use one core, since the single-core HAL and the multi-core HAL are different (HAL = Hardware Abstraction Layer)


Regarding RAM it's all different, for example my DDR3 RAM is normal 1.5 volt RAM up to a certain speed, but then it's rated at a faster speed at 1.65 volts... So it's basically RAM that's pre-tested for "overclocking"

Memory is almost always more stable at higher voltage, so if you're having stability issues, you can usually tack on 0.05 volts or so...

1.65 can be set in the BIOS... some BIOS support XMP profiles which setup the higher-voltage and speed settings automatically... if not, just crank up the voltage to 1.65 and check the speed and timing is correct according to memory documentation.

so when i pop the memory in the voltage would probably be 1.5v then?

No effect on performance.
Maybe on the potential of your frequency/timing combination.

Same deal with CPU voltage.

Wait, what kind of temps are you getting with your cpu? Too much heat and it will downclock itself. Those run relatively cool however.

Anyway, if you have a 939 chip in your old rig that has a 2mb total cache, it would make sense that it seems faster. Each core can theorhetically move more data at once due to the larger cache. That would give the impression of it being "snappier". Its just a theory I came up with. Its totally irrelevant tho if you're old cpu is 2x512mb cache.

I don't think that basic tasks like internet browsing are gonna be that much difference between processors. The speed difference is seen in the more cpu intensive applications such as gaming, benching, etc...
