Over Recommended Voltage Question

post #1 of 4
Thread Starter 
High I have some Ram that needs 1.85V to RUN

I just picked this up at work.
http://www.newegg.com/Product/Produc...82E16820231275

Max voltage 1.5V

What would happen if I run it at 1.68V with the 1.5V in with the other RAM?

No problem, Unknown, SOL


-ARKaMAN thanks

First off, in general you shouldn't be mixing and matching memory modules. You basically have to set everything at the lowest net settings, or be prepared to tweak it until it runs just slightly better than that.

You also have bigger problems than just voltage. When you run memory modules, they all have to run at the same voltage, speed, and timings. This means that you'll be running your Mushkin memory at the low speed and looser timings of the G-skill modules. Now, since the Mushkin modules are probably pretty high quality, they may very well be able to run at the speed and timings of the g-skill memory at 1.5V. So that's what I'd do. Set everything to the stock settings for the G-skill memory and see if it works.

Again, all memory has to run at the same settings.

Since memory becomes more stable as voltage is incresced, stability won't be a problem. The problem is too much voltage, and you don't know what is too much until the memory fries.

I would guess 1.68 would be OK.

Higher voltage does not necessarily increase stability. All it does is increase the high/low margin for transistor switching, which helps prevent floating states. However, the higher voltage does increase heat, which can undo those effects. Furthermore, there may be artifacts in the silicon that make certain islands of voltages or frequencies unstable because of resonance or other strange material properties.

Furthermore, that's A LOT of volts for those modules. A 12% increase over spec. Since those a are budget modules, I'm not sure they could take it.
