Hi all, not sure if this has been posted elsewhere, but i have some questions on the QX6700 overclocking with the asus commando mobo.

Ive recently had many attempts to oc my qx6700 but none have been very successful, the recent 2.8 (280x10) ghz was rather stable...with 1:1 fsb memory clock speed at 1120 mhz (1066 mhz is my memory's stock speed)

tested orthos for an hourish and its stable but the temperatures are kinda high... 75-85 ish celcius on each cores (using core temp) on load and 65-70ish on idle
asus pc probe on the other hand showing 60-65ish celcius on load and 45-50ish on idle (wtf difference?)

i tried to push it to 2.9 or 3.0 but it just crash/bluescreen/unable to boot up... a few 2.9 attempts was "somewhat" successful, but orthos is giving me errors, so i doubt it would be stable to run with that clock speed. at the same time, on load each cores was running on 95-100 celcius
and pc probe showing 65-70 celcius, thats rather.... horrible i have to say.

any idea on the heat issue? or its my vcores/other voltage settings too high? im using a big typhoon VX as cooling with the thermal paste that comes along with it.

basically im trying to push for a stable and not insanely heated processor that runs at around 2.9 or 3.0 clock speed. appreciate if i can get some advise/help/guidance on this. (im a total newb in overclocking btw, first time attempts, and on my new expensive rig XD)

increase the voltage to cpu... below 1.45v should be safe.. back down the memory speed/timings.. stabilize the cpu at your desired speed first before increasing ram speed.. increase ram voltage as well... dont exceed 2.2v

fsb:dram .. 1:1.. would be 280:280(560MHz).. if your RAM speed is at 1120MHz.. then you are running at 1:2 ratio.. 280:560(1120MHz)

Need to know. Are u ocing on stock HSF?

Read properly:
- This is what TS said in the first post:

ive set the vcores to 1.5 still want to increase?

after digging through this forum a bit i just realized i noobed on the vcores and its a lil too high that whats needed... causing unnessesary heat...

but my fsb i run at 300, 10 multiplier... guess that still isnt right... so basically pump more on fsb and lower multiplier to achieve 1:1 fsb/ram ratio?

wow, so low. i can easily go to 3.4GHz. I think ur CPU got problem.

or are you pushing with 1:1, maybe your Ram issue??? not ur CPU?

your present ram ratio is too high.. not at 1:1.. but at 1:2 as I pointed out. FSB beyond 333MHz is possible.. worst to the worst increase the multiplier to 11 or 12...

p.s. I am running my qx6700 at 370MHz FSB.. aiming to go beyond 400MHz on a P965 DS4

maybe vcore issue, set too high and causing a lot of heat problems.

and yeah im trying to go for a 1:1 ratio, thing is my ram default clock speed is 1066 mhz and its quite a waste if unable to get at least that, but im also trying for 1:1... so yea atm running on 1:2 as beastx pointed

beastx: umm if fsb333mhz is not possible then how ur pushing for over 400 and actually running at 370mhz currently? let me know please

and whats the multiplier do actually, besides being the multiplier to the fsb and resulting the end clock speed of the processor (thats all i know bout the multiplier currently)

Multipler is there for intel to set to mark on their processor speed for the market according to the grade of the processors based on stable default speed at a certain voltage.

QX6700 and all the extreme processors are unique in that you are free to set the multiplier to that u desire.

Your problem is most likely that you are pushing your RAMs too hard, When you get a stable cpu speed at 1:1 you can adjust the ratio to 2:3 or 4:5 so that your RAMs would be at 1000MHz or so.. adjust the RAM timings (5/5/5/18..6/6/6/24.. 4/5/5/18 etc..5/6/6/20) and voltage accordingly(up to 2.2 would be ok)

If 280 fsb is all you can do the by all means increase the multiple to 11.. that would bring the cpu to 3.08GHz. I reach 370 by dropping my multipler to 9.. to get to 400 and beyond I may have to drop to 8 or 7, all the while keeping the cpu vcore within 10% the default voltage. There is also chipset/FSB/bus voltages to consider. Increase FSB speed would be better than multipler increase is because it increases bandwithwidth for more data feeding the 4 cores.

sorry. but i dont think u need a new thread here. please use the ones above
