3500 overclock/Core temps

Try the 133 memory divider and 240 HTT just in case 166 makes the board run the memory at tighter settings making it unstable as the overclock takes it back up to 200. I have my memory settings configured manually to get around such problems.

It shouldn't do because 10 x 230 with RAM on a 166 divider puts the RAM at 191MHz and therefore not even at stock. Reset the CMOS, then when you're ready to try again, I would try upping the vcore up a notch.

Battled on and reached 11x214, x4HT, 166 RAM if I try 215 its no go drop to 214 everythings 100% ok. Tried different combos with no success. Upped the voltage from 1.4 to 1.55 still no go. I'm not sure but I may have read of a prob with my MB (Gigabyte GN-K8N-SLi) going over a certain FSB any ideas or comments?

What I mean is if the ram has SPD settings for DDR333 (ie. 2-2-2-5) which are much tighter than it would run at DDR400 (ie. 2.5-3-3-7) then when using the 166 divider the motherboard automatically uses the DDR333 SPD settings and so the ram when overclocking heads closer DDR400 it can cause problems due to the tighter settings.

I set all the memory settings manually to get around that problem.

Can you tell me what settings I should try? I haven't quite grasped the memory timings yet. I think the current settings are 2.5, 3, 3, 8 but don't quote me as I'm on a differant PC. Also after 4 hours of Neverwinternights 2 my core temp according to speenfan was 55deg, normal, bit high, too high????

Well you can just set it manually to 2.5-3-3-8 although AMD 64 motherboards usually have various other memory settings that might require manual configuration too. My DFI NF4 Ultra-D has about 15 settings and I managed to get them all manually configured with the help of A64 Tweaker to learn the defaults set by the board and also some threads on diy-street containing example memory settings.

I suggest you try 133 or 100 for the memory and 240 HTT again. If it doesn't work then bump the CPU voltage up a little although you probably won't need to go much higher for 2.4GHz. If the default is 1.4v then try 1.425v or 1.45v or whatever but probably not a good idea to go higher than 1.5v depending on your cooling.

Also you might want to download CoreTemp and use it to monitor the CPU temperature although maybe it'll report the same as SpeedFan as I haven't used SpeedFan in a long time.

I'd say 55c is reasonably high for default CPU volts but it depends on factors such as case temp and how good your cooling is at getting the hot air out of the case.
