Kingston HyperX KHX3200AK2/512 Problems :(

Been working on a build for a friend - and we are having problems with his stability and ram.

Pertinent specs are:
XP-M 2600+ @ 2.4ghz(stable as I can get it right now)
Asus A7N8X Deluxe r2.0
(2) 256 HyperX KHX3200
FX5900 Ultra 256

Here is the issue that I have with the situation. His ram defaults in bios to 2.5-3-3-8 @ 200mhz @ 1:1. Set to SPD, its the same specs. Only when I lower the mhz to say, 166, 133 or so - do I get improvement in timings.

This ram is supposed to be stock 2-3-2-6-1 @ 200mhz. So to test it, I threw it into my system at stock speeds (P4 3.0 @ 200fsb, etc). My ram has the same stock timings, cept its corsair(sig). It defaulted at SPD to the same crappy timings of 2.5-3-3-8 @ 200mhz.

Is this ram defective? Should I get him to RMA it? Or am I overlooking something?

Thanks!

isnt there an option to set to custom or something so you can set the timmings your self to see what it can do and give it all the volts you got

Sure is, and if I set it to its supposed stock timings/speed - it wont boot.

put the rated timmings in and set the vdimm as high as it can go

Keep in mind that that RAM is probably CH-5, which doesn't like tight timings much at all. Like Sophisticated said, trying cranking the voltage all the way up. If that still doesn't work, you could probably get the RAM RMA'd.

I'm having the same problem... Same RAM, I'm not really sure what I'm going to do.

I'm using an Asus P4C800-E Deluxe mobo and I called up Kingston and now I've got it running at 2-3-2-6. I have voltage at 2.65 and what you need to do is slowly overclock each timer. I did them like this:
1. 2.5-3-3-8 (save and exit) |
2. 2.5-3-3-7 |
3. 2.0-3-3-7 |
4. 2.0-3-3-6 |
5. 2.0-3-2-6 V

And it works fine now, I get higher scores on 3DMark03 as well .
