Strange Memory Problems

[cardzz]

I have a K8N NEO2 Platinum with strange memory Problems.....

I have 1024 MB (2 x 512) of TwinX 3200LL (2-3-2-6 1T) that it seems to

refuse to go any faster. When I'm trying to overclock

I set the "divider" to 166 Max Memclock and leave the timings at

2-3-2-6, run the FSB to 240, and, when I can get it to POST, the

memory test runs and then it says Memory clock is 166 Mhz ?????

It should be 200...right? When I put a single stick of Samsung

PC3200 (3-3-3-8) it changes with the FSB...@ a FSB of 230 the

Memory Clock reads 191 Mhz, @ 240 it says 200Mhz, boots and runs fine in single channel mode. Why won't the Corsair change from 166Mhz??? Is dual channel different?? Is the Corsair somehow locked??

Have you tried using only one Corsair module at a time? You should also relax the timings to 2.5-3-3-7 just to see if it's your memory controller having issues with the low latencies and higher clock speed.

 

Overclocking the integrated memory controllers is a bit complicated, to be honest.

I will try 1 module at a time, but kinda defeating the purpose of dual channel isn't it?

 

Also, It's not really a higher clock speed is it? 200 FSB (pc3200) is 200 Mhz (DDR400) 1:1 ratio right? So, 240 FSB @ 5:4 ratio is also 200 Mhz as far as the memory is concerned, sio I shouldn't really have to relax anything.(I didn't have to with the samsung, it ran at rated speed)

 

It just bothers me that a cheesy stick of Samsung RAM out of my wife's e-machine (retail $399.00 including a 17" monitor) beats my $300 Corsair RAM!!

The 1 module idea is only for testing purposes to eliminate variables. Also, in the past , the MSI bios' do some wierd things, especially when it detects low latency RAM. And, when you add in trying to run asynch, that can complicate the issue.

 

In addition to running a single stick and reducing the timings, have you tried to OC at a 1:1 ratio? Just for testing purposes, can you try the whole deal at stock (200/200) and see how it does? That should show you if it is the RAM or the MOBO.

 

Hang in there, you'll get it sorted. Mike.

 

PS: I forgot to ask, are setting the timings manually or using SPD timings?

I hear what you're saying, but it's not quite that simple.

 

Please, try one module at a time or both at 2.5-3-3-7 and see what happens.

 

Also, you might want to run at stock and test the modules at 2.5-3-3-6 by running Memtest86+ to see if the toss up any errors.

Tried them one at a time and the meory clock at the boot screen does change, but I can't get much past 210 FSB on either stick.

 

I haven't tried stock settings and an overclock.....DUH! I guess I just assumed it wouldn't work!

 

BTW it runs great at stock speed!

 

P.S. I've used SPD and manual.....You see, when you drop the Max Memclock (divider-Ratio-RAM speed whatever) from 200 to 166 the memory automatically wants to go to 2-3-2-5 1T instead of default 2-3-2-6 1T. That being said, You manually have to change it back to default or more relaxed because it's "really" not 166, after the FSB is overclocked it's back to 200.

 

This is giving me one hell of a headache!! :bigeyes: LOL

 

I'm just gonna get me some G. Skill PC4400 and call it a day!
