Memory problem on Epox 4sda

I recently got a 1.6 NW and 4sda which overclocks well upto 2.13 (133 fsb/ memory 166 ) and also a bit further to 139 fsb with memory at 1/1 ratio.
The problem is that when I try to push the memory (DDR 2700 Samsung Major on 3rd ) above 166Mhz it becomes unstable. I have tried raising the voltage as high as 3.0v and using the least aggressive settings. I have also tried three different sticks of Samsung but still no luck.
I can get it into windows at higher speeds and it will run for a while so long as it does not get pushed to hard i.e. gaming.
Anyone got any ideas what could be holding it back?:nervous:

Use bios 2408 and 2.7v you should be able to do alot better than 133cpu 166memory.

Maybe you have a bum stick or something I have tried original and 3rd party samsung and both do over 200 memory. None will do over 180 on the 4SDA with cas2 thou only cas 2.5.

Maybe just try different memory settings but trying voltage over 2.7 with samsung only seems to make things worse.

OK got it running now at 200Mhz YIPPEE!
What it needed was a gradual "Burn In" Here's what I did.
1 Used sandra memory bench too burn it for 4 hours at 166Mhz and 2.5v
2 Raised voltage to 2.7v then another 4 hours burn in.
3 Raised Mhz to about 180Mhz then gave it another 4 hours burn in.
4 Raised voltage to 2.9v then another 4 hours burn in.
5 Raised Mhz by increments of 5 Mhz giving it 4 hours burn in each time until I hit 200 Mhz
6 Played Counterstrike all day YAY...
This may be a bit overkill and it took about a day and a half but it totally worked.
I did not realise the burn in process was so important but apparently thats what it takes with the Samsung memory.
BTW thats 2 x 256 sticks:-D
Thanks for the reply Mr Fix It

Timings are 2.5,3,3,6 at the minute but I'm hoping to get them a little better. Don't want to go any more voltage though.
BTW I'm now up to 204Mhz lol :-D

You didn't post your actual memory results.

I can do ~2800MB/sec with the same timings at a 133MHz FSB and 2.94GHz on the clock.

That 1.6GHz will overclock higher but you'll need to go back to slower RAM again for it to be 400MHz DDR again at 160MHz FSB.

Scores 2951 Mb/sec for both Ram int and Ram float
Can't figure out how to get a screenshot onto the post though

Linear then, those are at 408MHz DDR you gave.

I will have some PC3200 in a few days so more agressive timings will yield better throughput.
