I recently built an office/entertainment PC for my dad. I put http://www.newegg.com/Product/Product.aspx?Item=N82E168... (Kingston 4GB, 1600Mhz, CAS9) in it. I just noticed on Newegg that the voltage is 1.7-1.9V which seems pretty high to me. (The site I bought it from never mentioned the voltage)
How simple is it to lower the voltage?? Is it just a case of going into the BIOS and lowering it there??
Also I would like to tighten the timings to CAS8 or CAS7 if I can.
Could you guys link me to a tutorial that would explain it all to a newb like me??
Yes you would go onto bios and lower it. If you're going to use tighter timings, you might need to use the higher end of voltage specification. Best way is to experiment and test. Why not go with two sticks of lower voltage dual channel ram?
