Max Safe Voltage for DDR RAM - Page 2

I'm guessing this is the value DDR400 RAM?

If you're using infineon chips (I'd like to know which ones) your max voltage will be around 3.0v, after that you won't see much, if any help from voltage increase. You'll be fine at 2.9v unless your sticks are ready to die anyways. You'll probably be looking at 225-235mhz max for a standard infineon DDR chip.
Stick 1:

Part No: 64D64320GU5B
Serial No: 08368E27

Stick 2:

Part No: 64D64320GU5B
Serial No: 074D6322

Infineon, just like PROMOS doesn't scale well with voltage, so you're better off letting it stay at stock (2.6v) voltage and see what you can get out of that. I had some impressive timings on my PROMOS stuff and 184MHz.
Couldn't care less about timings unfortunately as it has a negligble effect on gaming performance, RAM speed on the other hand.....

see if you can take a real clear picture of them or put ALL the info off the IC chips themselves...

The serials off the stickers dont mean much...It really depends on what IC's you have till we can give you the best advice...

Kingston, like all companies used all brands of chips and they all act differently...until we know exactly what you have we wont know how to help you...

if it defaults at 2.6v you could have Infineon or TCCD or such ram.. I wont expect too much out of Infineon with older stuff..I got mine up to 240ish but that was about it...And they do NOT like voltage...they did better on less...2.65v max on mine...2.7v made errors at 225

Try loosening your timings and seeing what sort of bandwidth you get compared with tighter timings. It helps.

I'll try getting a pic of them but I currently don't have a camera. Will try borrowing a cam phone or something.

But won't anything less than 3-3-3-8 lead to degraded gaming performance? Also isn't it loose enough?

Anyways I've got it now at 2.5-2-2-5 1T stable at 2.7v.
