Could someone clear this up for me?

Hi, I bought the Geil Ultra DDR 6400 Cas 4 kit from OCuk this week. On Cpu-z and everest it's saying that the memory is DDR2 667 PC5300 RAM. Why does it say that? Does it mean that the memory modules I have aren't PC6400 but 5300??

Could this be why I can't change my timings to 4-4-4-12 from 5-5-5-15, without the computer rebooting on me?

What should I do?

Many thanks.

I increased the voltage to 2.29V (increasing it further would be higher than the highest range according to Geil (http://www.geilusa.com/proddetail.asp?linenumber=74 , with the changed timings. Managed to boot up into windows, but then system rebooted again, and BIOS returned all settings to stock.

Just tried single sticks and swapping around with them to avail.

Do you want me to take a picture of my BIOS?

Is there anything there I need to change?

2.00 is the lowest it goes.

All those settings are as it's stable right now.

When I drop the timings, I increased the Vcore to 1.38V, increase the VDIMM 0.425V to 2.29V.

I also increase the MCH another 0.05V.

Still it's not stable.

I guess there won't be that much difference between CAS 5 and CAS 4 in normal computer usage/games. I think I might try the F3B BIOS. Just need to know where I can download it.

Ok, after installing the F3B BIOS, I've loaded up CPU-z and my CAS latency is now set at 3. With timing of 3-5-5-15.

I'm just testing the RAM now.

Should I put it back to 5-5-5-15 or something else?

Edit: CPU-z says it's at 3-5-5-15. But the BIOS says it's 5-5-5-15. :/
