i7 Overclocking......

AeoNGriM · 21 Sep 2009 at 15:41

I know it varies from chip to chip and setup to setup, but as a rule what is the max an i7 920 can/should safely overclock to?

As far as you want to push it mate!

Most folk here aim for 4-4.2GHz, but I know guys running 4.5GHz under water.

i would worry more about temps and voltage rather what it can clock too. Both are on the intel spec sheet.

Thanks guys!

I've seen people pushing loads more voltage through their chips than what the Intel Spec Sheets say, though they are using extreme cooling..

running mine at 4.2 ghz with vcore 1.28 - max temp is 80c

True mate but he said safe, i would not like to recomend to lets say a newer member of the community to shove 1.x volts etc just cause the XS guys do if you know what im saying

Indeed.

I would say 3.8-4.2 depending on chip, anything more is a bonus.

I would say 4.0 using 20X200. That way, your memory will run according to spec. I could be wrong though.

If he is using 1600MHz ram then yes, but tbh, using 191x21 wont make much if any difference to performance.

True. there's no noticeable difference but not all Mobo's likes the 21 multiplier. I also noticed that my Mobo Asus RIIE is showing different TDP's as the multiplier varies.

191x21 = 150.xx W
200x20 = 130 W
211x19 = 111.xx W

Something which I believed affects how hot your system will run specially during benchies.

i know my board doesnt like the low multiplier+high fsb situation. To get my i7 near 4ghz i have to use 21*186 (3.9ghz)

reygjabla · 21 Sep 2009 at 20:02

What board are you using?

samir_ansari · 21 Sep 2009 at 21:00

biostar x58

reygjabla · 21 Sep 2009 at 21:05

Have you tried the 20x200?

samir_ansari · 21 Sep 2009 at 21:09

yep, wasnt stable for me, although im pretty sure its my chip with the limit and not the board actually - I have been reading that the board is a very good overclocker

reygjabla · 21 Sep 2009 at 23:33

Have you tried upgrading the BIOS? Could benefit your mobo some way or another. Me? i've done 5 or 6 bios update before I manage to clock it stably.
