Howhigh can I set the voltage?

post #1 of 16
Thread Starter 
I just got DDR2, and I have been playing around with it lately

This memory seems to like voltage, since I have already got it to 916mhz on 2.1v.

How much higher should I set it? I have plenty of cooling with a 120mm fan from my gemin right over it.

They say keep volts < 2.3, or +.2 over max (ie my HZ's are rated for 2.0 to 2.1 and that means 2.2 to 2.3 is fine)

Fishie.. you might read through this thread. It will give you a good idea of what's happening with DDR2 and voltage.

THanks, any idea what chips I have? That thread only seems to apply to D9's.

I would be very careful going over 2.3. DDR2 was only meant for 1.8V. It is being stretched to the limit. D9's are good chips, but they have a high failure rate.

2.3? Sounds good, that's .2 higher than where I'm at now. I'm hoping it will let me get to 1000mhz. Hey, one can dream, right?

Also how do you know it's a D9?

You take off the heatspreader and look, to be sure that is, and yes over 2.4 it seems that d9 chips start failing if they are ran at this voltage for very long.

Less the 2.4, I wont run mine over 2.2 without active cooling but thats just me.

The d9 chips have a high failure rate because people push them to the limit, when you run ram at 2.6 or 2.8 they will fail (ddr2 anyways) and people do that with d9 chips hence why you see the oh my ram died oh but why

For 24/7, stay at/under 2.25V.

I did tests with my ram at 2.45V, but will never do it again.

The only thing holding my heatspreaders on is this squishy white tape between it and the chips. There is no clip over the top like most. Think it's safe to pull it off?

I would be careful removing the heatspreader. I have heard of people actually pulling a memory chip off the PCB board.
