Hi y'all!

Just wondering if the voltage for DDR2 4-4-4-12 800MHZ would be the same with DDR2 600MHZ 3-3-3-9. I read somewhere that these two settings are theoretically the same performance so I thought the voltage would be the same. Also, which one would be hotter?

Thanks in advance!

The voltage is probably going to be the same (1.8volt). They should offer about the same performance. Going below a certain frequency though, can hurt the performance. The 800mhz ram has the advantage to be able to sync with the fsb 1:1 for overclocking. I would think the 800mhz ram would run a little bit hotter. If they are the same voltage, the temps aren't going to be far apart though.

all memory sticks have different voltages as spec'ed by the manufacture, look on the website or package and it should tell u, most high performance sticks are 2.0 to 2.3 v

The JEDEC standard for DDR2 is 1.8V. Advertising that you don't meet the spec doesn't make it ok.
Buy most Mushkin (or even A-Data), and it will run at its listed timings at 1.8V. Buy that Crucial, or OCZ, or Corsair that is 4-4-4-12 at 2.1V, and chances are it will be 6-6-6-18 (or worse) at 1.8V. What does that suggest about the OC potential of the Mushkin?

Thanks for the quick responses. I already have the ram, I was just wondering about the settings. Currently I'm running 300MHz FSB, and my ram's spec is 4-4-4-12 DDR2 800MHz 2.2V - crappy ram. So if I were to run 600MHz, proportionally, the timings should become 3-3-3-9 to theoretically have the same performance.

The big question here is, what voltage? Common sense tells me it's 2.2V, but I really don't know.

Of course I'm Prime testing it to get it stable, but knowing the answer to this question is helpful.

It's probably going to be 2.0-2.1v (I'm just estimating). Set it at 600mhz, then lower the voltage until it's not stable anymore.

Exactly what I was doing, except computer would freeze at any voltage level. Stupid ram, can't even handle the tighter timings.

Change of plans. I did 333MHz and the ram's default settings of DDR2 800MHz 4-4-4-12 2.2V. This was my original setting and looks like I'll have to live with it until I get some better ram.

Thanks y'all for ya help!

its always best to run at 1.8V and try lower your timing until it become unstable.thats how you do it.
