halo.... i'm now using an i5-750 with asus p7p55d motherboard with kingston hyperx 4gb ddr3 1600 mhz....
so my question is... at what voltage which is considered correct or i should say... safe for overclocking my dram???
because i read at bios it stated that my dram voltage is at 1.7++v........ can anyone answer me about this?? because i'm still very new in overclocking..... thank you....

Do not increase DRAM voltage over 1.65v it could damage the RAM controller which is intergrated into the CPU.

Don't mess with your RAM voltage too much. 1.65 is stock for those Dimms and personally I would leave it at that really no need to go higher then 1600mhz all you will be doing is creating more heat for very little real performance gain.

And that could happen too.

Well JEDEC spec is 1.5V, Intel max is 1.65V. I would not ever go over 1.7V, but IMO if you need to bump it up to 1.66 or 1.67V it shouldn't hurt (but, since it's over spec it could, possibly, hurt). I know that some mobos don't have 1.65V, only 1.64 and 1.66 and most people will then run at 1.66 no problems.

Anyway, yeah, do not go over 1.7V, at that point just increase the timings and drop the voltage. RAM doesn't make a huge impact on performance (because it's already lightning fast)

I don't mean to hijack this thread, I just have a relevant question. You guys mentioned that going over 1.65 V is not good, but my Kingston PC2-5300 (667Mhz) sticks currently run at 1.84 V at average, and I never overclocked anything in my system. Is this bad or what? The sticker on both sticks says "1.8 V".

DDR2 is a higher voltage RAM that DDR3 so 1.8V is fine yonyz

Standard voltage for DDR2 is 1.8 volts. Stand voltage for DDR3 is 1.5 volts. Don't compare apples and oranges. :)
