POOR (1st) overclocking - Page 2

My advice with the board is to find the thermal-throttling and turn it off in the bios...
Cool'n'Quiet?
Smart CPU Fan?

Well, I found that not everything was exactly stock. I forgot to re-set the RAM timings.

Now that everything is normal, OCCT passed over 4½ mins w/o problems.

I have the impression that my Corsair XMS can't handle the "guaranteed" 2-3-3-6-1T.

Just a moment for the screenshot...

Here it is. With stock speed and voltage.

You can trust me on this one, Core Center's volatages are usually way off. It says 1.49, my actual is 1.45. So it is best not to trust it, or any other software monitor for that matter.

Like the stock voltage, which is currently set, is 1.35v, and Core Center displays 1.40v.

Also, 12v, which measures 12v on my DMM is 12.3v in Core Center.

What I find strange is that it AMD Power Monitor always displays the same core voltage.

I think that the solution is to return the computer to the shop so that they can check it. It's a bit unstable even with the stock params. and can't overclock or run at Corsair XMS guaranteed timings...

Read the fine print. Corsair XMS 3200CL2 is only CAS2 on Intel systems. On an AMD, you have to go to CAS2.5. I've got the same memory and they wouldn't even run at CAS2 at 166Mhz.

From Corsair's product specs for TwinX1024-3200C2 :
Quote:
Tested at ultra-low latency settings
- Tested at 2-3-3-6 settings on Intel and AMD platforms
http://www.corsairmicro.com/corsair/...024-3200c2.pdf

On the "SPD Timings Table" in CPU-Z it states
200MHz 2.5-3-3-8
166MHz 2-3-3-7

In fact, it seems it just couldn't run with 2-3-3-6 timings with CMD 1T : With 2T and 2-3-3-6, Torture test in OCCT ran over 4 mins without problems.

Just before posting : I looked in Corsair's FAQ and there it states 2.5-3-3-6...

I've been able to run at 2.5-3-3-7-2T 218MHz FSB but lowered to 215MHz just to be sure. Got the NB @ 1.30v and Vcore @ 1.45v. I also run the RAM to it's 2.75V spec instead of 2.6v now.

I was able to run 2-3-3-6-2T 200FSB and 2.5-3-3-6-2T 210FSB.
I didn't try RAS 6CLK with 218FSB. All I know is that 220FSB doesn't work.
