8GB (4x2GB) F2-8500CL5D-4GBPK stable config???

Asus P5K Premium
Intel Core2 Q6600
2xF2-8500CL5D-4GBPK

What are the recommended memory bios settings for using with 2x F2-8500CL5D-4GBPK Kits with my Mobo??? Can i use the memory stock/default settings (1066mhz 5-5-5-15, 2.1v) with stability and good speed???

[GSKILL TECH]

Yes, but in addition to the basic DRAM settings, you will also need to raise the NB Voltage to 1.40V to stabilize the memory controller. Also, tRFC timings may need to be increased. Keep us posted on the result.

Ok thanks!!!!And If i use the modules in DDR800 4-4-4-12 2.0v? No need to increment NB voltage...so no need to add stress to NB...??? Isn't that right???

[GSKILL TECH]

Depends on the NB, so if it is slightly unstable, you can try to increase NB Voltage a little bit to see if it can be better.

Thank you

ok than...
When you say in your first answer that i need to put the NB voltage in 1.4v, ist's a must...? If i don't it won't work???

[GSKILL TECH]

Yes, motherboard Northbridge (memory controller) will be overloaded with full slots of DDR2-1066 2.10V

Thank you

One Last question: and this two configurações hipotesys:
1066MHZ 6-6-6-18 1.9v 4x2gb
Or
891mhz 5-5-5-12 1.8v 4x2gb

With this two configs the NB can be at stock voltagem?
Thanks once more

[GSKILL TECH]

Maybe, you will need to test to find out. If the system is unstable, then you know you may need to increase NB Voltage to stabilize memory controller.

Ok i now i can test, but as this memory kit is in market for a couple of years from now, possibly you could already have seen those configs working on iP35 motherboards (stable), without needing overvoltage of the NB...and than through your valuable feedback i wouldn't need to do experimentations...know what i mean??? that's the basis of my question formulation!
Thanks for your support!!!

I am getting a stable 8GB system with 2x4GB F2-8500CL5D-4GBPK with following configs:

Dram frequency - 1066mhz
Dram timings - 6-6-6-18
Dram voltage - 1.95v
NB AUTO - Without overcloking the northbridge!!!!

Greetings!!!

Update- i put the NB voltage in standard value which is 1.25v...Still stable!...evaluating..

[GSKILL TECH]

Good! Keep testing for your ideal settings. Each memory kit and system is slightly different, so when overclocking, experimentation is necessary and inevitable.

I am testing 1066mhz CL5 8GB with NB auto...system stable for now...just NB idle temp rised from 35 to 37c...load temp 39c...i have played the new tomb raider for half an hour and no sign of instability. Do you think is to stress for NB...should i reduce to CL6 1.95v 1066mhz???

Thanks
