Voltage Question

post #1 of 12
Thread Starter 
Right Now I have 256MB x2 of Corsair Value Select Ram in my computer running at 2.6V which is stock for my mobo's Ram voltage. I was wondering what voltage I could go up to without damaging my Ram. My mobo only goes up to 3.0V for the Ram and, also I don't have any heat sinks or heat spreaders on the Ram (Its just the bare chips themselves).

Hello and welcome to the forums Wilson,

I would personally not take value dram any farther than 2.8V. That being said, if you are not able to tighten the timings of your DRAM with a vdimm raise then there is really not any need for the raise. Are you at all system overclocked?

Yea, my CPU is currently overclocked @3.55GHz from 3.06GHz stock with 1.4V for my CPU. I want to overclock more, I believe I can because I have no heat issues at the moment. I can't OC anymore at the moment even when I up my voltage to 1.5V for my CPU, and I think my CAS latency is to blame (its at 3 right now)

Try setting a divider for the ram to make sure it's not running out of spec. That should do the trick

It's just a bios setting that lets the ram run slower than the FSB. It might be called limit mode or memclock max.

Here is the download for your motherboard manual:

http://www.chaintech.com.tw/download.../V915P(V2).pdf

You will notice in your BIOS setup a section called:

"Frequency/Voltage Control"

and a setting called:

"System Memory Frequency"

To set a lower memory divider you set the memory lower than the CPU. If your ram is PC3200 DDR400 then you would set the DRAM Memory Frequency to 333. Then when you overclock you will get a raise of both the CPU and RAM. Since the DRAM is lower than the spec, the raise will not render instability.
