Nanya Elixir ! don't think you'd get much of them ???

For psus, grab a Corsair HX-850 should keep you happy for a few generations of upgrades

Well, the chipset seems to be the limit for memory at most scenarios. 1600 is barely stable at 9-9-9-28, and 1.9v but at any lower frequency i can change the CLs quite much more.

For 800Mhz the configuration is 5-4-4-12 (or 8 or 7) at 1,5 volts. This also proves that these sticks can run on 1600 on 1.5 volts. Seems that the board has really bad trouble with power supply of memory when voltage is bit higher.

If those sticks will not be overclockable (as they are not) they will be at least good vantage point for detecting issues on memory or chipset side.

Note that 1600Mhz 9-9-9-28 is gives 65 000 3dmarks and 800 5-4-4-10 gives 65000 3dmarks too. No change of performance at all (while FSB 400). At all this system will be quite limited. Even FSB 450 is too much for the system, CPU can boil any water at this frequency. FSB 433 should be fine, while i will test whether lower CL or faster frequency will improve system performance.

99% sure it's problem with specific memory modules' ics you're using. Different modules give the chipset different levels of stress.

For now i just now that 800 mhz 5-5-5-14 at 1,9 volts is unstable same as 1600 9-9-9-28 at 1,9 volts, but 800 5-4-4-10 at 1,5 is 100% stable. Much more a power supply problem. Strangely that overvoltage can lower stability. Maybe somewhere is acumulating heat.

Today i found Corsair HX650w at the store near my house. Quite strange while i prefer travel across the city to different store

1. I thought that i bought PSU which was somehow damaged. The tables i had for OC prepared with old PSU were unusable instantly.

2. I set voltage for memory to 1.9v, FSB to 400. CPU was a bit OCed so its voltage is now set to 1.3v. NB and SB are running on default settings, while I am constantly lowering VTT voltage. Now I am at 1.205v and system stability is unaffected. At all values are exellent, including temperatures.

3. Now it seems that 1.9v is some kind of Default value for memory controller. This specific voltage setting for memory can cure any other trouble which occurs with the system. This might help a lot when overclocking the CPU and the board itself.

At all I dont believe that Nanyas are best in the world - i did not expect that when I bought them, but now it seems that best memory should be 1.9v tolerant.

I began to perform standard test. For me it means to set all values to "on" when i am sure if the feature is supported. Also i set FSB for 400 during this phase. Also it means that i set voltages to lowest or default values (except cpu which ic OCed, and memory while it cannot run on lower voltages because of chipset)

Results are disturbing. Computer is unable to boot while memory runs at 1600 and timing and memory features are on "high" settings especially the "enhanced data transmitting". Also co mputer may freeze at random during gameplay. Might take some hours until computer fails.

CPU power management is excellent. Temperatures are also very good, but it is certain that for better OC water cooling should be necessary for CPU. This piece of silicon is not the best one, but i have to remember that i dont use any of power saving features.

Overall system performance is just amazing. Only thing that i need to upgrade is memory to 16 gb.

Mostly all failures during this phase of testing is memory. Not able to run XMP2 profile althought it is supported both by board and memory sticks. Several functions does not work fine.

End of test:

So the testing took much longer i expected. Hopefully the results might help.

First of all i replaced PSU as you know - Now i have one 650 watt corsair. This changed everything, mostly VTT voltages are now much lower. Then I set everything to default.

FSB 400 is default for the board and RAM but not the CPU this was only OCed part during the test and the CPU core voltage was the only thing which had to be tweaked.

Memory voltage has to be set to 1,75 since x48 does not support lower voltage for 1600Mhz on Memory.

Tests by Linx show that sometimes first test will fail. Reason was unknown for a while. even when CPU and VTT voltages were a bit rich the situation persisted.

Symptoms were strange:
- CPU temperature was cca 5 degrees lower then the test failed everytime.
- the performance was half of three quarters of test which completed sucessfully

Solution was to add some voltage to Northbridge core. After that the issue cleared and never repeated again. This confirms that the Board has some problems with power. On the other hand the CPU power supply worked during this test great. Energy provided to CPU was stable without any major trouble.

CPU voltage issues but seems much more complicated. Once i start tests with 3dMark2003 (which uses only single of CPU cores) the test crashed at the beginning of the "Trolls lair". Previously i calculated that 1,45v should be enough for overclocking of x3360 from 333 to 400 fsb and it works. With this voltage the test passed sucessfully and later when i lowered it to 1,375 it worked too. Only thing that differs from linx is usage of graphic card.

Interesting but indeed a good psu might change the voltage requirements
