DDR2 Ram Max voltage limits? for non heatsinked ram

post #1 of 8
Thread Starter 
So forsay some Generic Kingston Ram can I push 2.1-2.2volts through them?
I got them running at 800mhz DDR2 at 5-5-5-18-24-2T with 2.1volts

I have all 4 slots populated will this be dangerous? In terms of burning up my ram? Because they got no heatsinks on them_

I think more important is if you have any air that blows over and through your mems versus having the heat sinks. Mem heat sinks in general have very very little effect on mems. Also try to stick to the rated voltage for your mems, if you are OCing going 0.1 volts higher than rated should be fine.

Memory is rated at 1.8volts only_ and I sorta doubt I have a good enough airflow towards them =[

RAM is rarely heat-affected or heat-limited, even with non-heatsinked modules. You'll probably run into issues of stability at a frequency determined by the quality of the RAM/modules rather than any issues with temperatures.

Yikes, you need 2.1V for 800Mhz 5-5-5? I'm assuming they're highly generic with 800Mhz 6-6-6 rating or so?

I just brought them down to 1.995volts @ 5-5-5-15-24-2T

Running a few OCCT Linpack runs right now to see if they are stable_ I'm going to keep dropping the timings til I can no longer boot or til its not stable_

I'm going to see if I can hit 4-5-4-15-24-2T lol

Yes they are extremely generic lol with 6-6-6-18-24-2T at DDR2 800mhz clocks
http://valid.canardpc.com/show_oc.php?id=1809667

I can't seem to push the FSB anymore, its at 245 right now and I wish I could get it to 267 but anything above 245 just won't boot, not even 246 =[

I wanted to overclock the CPU to 2.4ghz!! but that seems impossible

Heres a current validation, This is my old rigg and now I finally got around to optimizing its overclocks =]

For DDR2 keep it below 2.3

Okay so right now I restarted the computer and got them down to 1.905volts 5-5-5-15-20-2T

Note* I started at 2.1volts just because I didn't expect them to boot at 1.9volts- I might be able to go lower =O

Not bad for generic Kingston value ram lol

I'm trying to aim for 4-4-4-12-18-2T if its possible on these cheap ram =]

Thank you for for inputing +Rep
