My mobo isn't very good for OC and can't set much more than about 240MHz for HTT (FSB), because that and the insignificant difference in prices between Athlon II X2 240-245-250 (my 250 costs me only 4€ more than the 245), so i bought the 250 just for the higher multiplier, i was sure that minimum i could get from 3300MHz (220x15) to 3600MHz (240x15) with my processor, RAM and mobo, and so it was...

The limit for overclocking too much my processor is that my mobo couldn't down the multiplier for NB, and it goes x10 (overclocked to 3600MHz the NB Frequency is at 2400MHz, less or more the maximum recommended), fortunately i could down multiplier for HT Link, so i don't go under 2000MHz for HT Link overclocking my regor, i setted at 1600MHz in the bios (x8), maybe at 1800MHz (x9) it could be stable too, but with SuperPi perform best HT Link at 1920MHz than 2160MHz. If i could change the multiplier for the NB maybe i could overclock my processor up to 3700-3900MHz, but with this limitation i couldn't go my NB Frequency above 2400MHz don't matter if i up VCore, NB core, etc... but well, to 3600MHz frequency for the processor and 960MHz for the RAM it performs very, very well...

Sorry for my bad english, bye!

g'day guys
Got a 240 the other week so thought id sign up and add it in here, reading on here was part why i got one.
was going to get a 6000 or 7750 a few months back but thought id hold off for a while and am glad i did.
the Regor seems a fair improvement over the older X2s.



at 3.4GHz it failed 4secs into OCCT but windows would still load at 3.5GHz so should go a fair bit higher if i could up the volts.
This Mobo only has options to change bus speed and ram volts in the bios though.
temps stay pretty cool with the stock HSF when the room temps arent too high,
probably wont cut it come summertime though as it gets pretty hot down here

By the looks of the cpuz, you're overclocking your memory too. Which often causes instability. Go into your bios and set your ram speed to 3.33x or 667 and try your stress test again.

yea the rams at 472 but its good corsair c4 stuff though. in all reviews i saw of it its made it well past this speed at the c4 rating, mines only running at c5 so should do it easily. i bought it for this reason as i figured i probably wouldnt get the option to change the speed with the cheap mobo.

I started on an ECS mobo as well, I dont care for the layout of the bios.

Paddy510, for testing purposes (as MRHANDS mentioned) try dropping the memory frequency a tad just to see if that helps with stability. Kind of a shame though that your motherboard does not have an area where you can change the cpu voltage.

Good luck

Good luck guys!
There's two reasons i got to these settings; max the dram speed, & the cpu has never completed booting (even safe mode) above 3.7
(266-7) * (13-13.5) is the other (more stable ) sweet spot since the cpu can set to around 3.5 ghz, mem ends up being just under 1066, & i can still push the fsb.

The other thing I've figured out is that the Asus M4N78 pro BIOS will remember the multiplier even when I go back to all auto. This makes it possible to then boot into windows and have the Asus AI Suite utils push the boundaries or not without rebooting & changing the bios settings.

I was able to get the 295 fsb(showing 293.xx on cpu-z) by:
1. setting the bios settings.
2. reboot back into the bios
3. hit the power button (while in bios) to reboot again
4. let windows attempt load.

My theory is that the 1st boot sets sets the values I entered, & the second boot recalculates the auto values based on the running entered values. It does seem to pause a few seconds longer than usual. I will try this a few times to see if I can reproduce. I found this last night , completely by accident, while i was trying to boot into a hard-coded 12.5 * 295 as I had a week or so before.

(insert blah-blah-blah here)

I've looked into coolers & the Ultra ChillTec Thermal Electric CPU Cooler looks like a nice cooler. If i went with the v10(monster!), there wouldn't be any room for the chipset cooler (or to crawl inside)

Okay this was just to see if it would load windows. I did run super pi 1m.

will have to try an see if its stable when i have the time.

ArthurDent, the memory frequency can still run at stock if you play with the multiplier...or are you trying to overclock the memory? Sorry I think I misunderstood you.

Badave, great job man

SuperPI 1M is somewhat of a good sign of stability. Hopefully you get positive results later on. That is a awesome OC!

Good luck
