Any idea why mine isnt down clocking? speedstep is enabled, voltage goes up when under load, tried different bios , setting it to default ,still same.

using a gigabyte GA-Z77X-UD5H

balbowa look in easytune/cpu see what thats saying

Ive sorted it thanks, id altered power options in windows 8, id set it to high performance, doh....

My Effort

my sandybridge set up died.. the board screwed itself up so here is my first tinker, set voltage at 1.28v (haven't tried lower) on a MSI Z77 MPOWER...tested on latest prime stress test for 2.5 hours or there abouts here are the results!

Nice low volts and good temps dude.

24/7 for whatever the user desires!!!!. HT is off as I am testing for a specific reason that does not benefit from having HT on. I did briefly test with HT on and its equally as stable.

5.5 goodness!! DDR is nearly 2600 mhz too with BLK of 107.9! the IMC is strong in this one!!

Prime!!!!

3570k at 4.5 GHz running P95

Ive gotta z77 mobo and 3570K to 4.6ghz but need at least 1.332 vcore to get stable I guess I got a bad draw from the silicon lottery.

8 Pack · 24 Jan 2013 at 09:33

^^^^^^^^^^^a lot of the later batches require higher Vcore.

Gangster · 24 Jan 2013 at 15:51

Quick, noob question here but what is the stock vcore for a 3570k? Is it 1.2v?

setter · 24 Jan 2013 at 15:55

It will vary from chip to chip. At idle, mine is displaying 1.000v ono in cpuz.

it depends on each cpu,some will be high/some low

just look in the bios at stock clocks/setting and see how much is being used for cpu voltage

in windows it will be higher as loadline calibration and offset will add extra cpu voltage

Gangster · 24 Jan 2013 at 15:59

Thanks guys

I guess the best way is just run stock and see what windows reports in CPU-Z?

setter · 31 Jan 2013 at 21:31

Tried the following earlier. Ran it for an hour without issues.

vcore, 1.2900, (1.272 @load, llc on high)
pll, 1.65v
dram, 1.57500.
vccsa, 1.01875

But im getting freezes when playing bf3. Have to ctrl alt del, error saying bf3 has stopped working.

wazza300 · 31 Jan 2013 at 21:54

Usually not enough CPU voltage,look in event viewer/warnings for any whea errors

setter · 31 Jan 2013 at 22:00

Yep, quite a few showing up in event viewer. Game ran for just over 5 minutes before freezing.

illuz · 31 Jan 2013 at 22:01

Hope you crack that 4.5 soon mate. Have you tried BLK clocking @ 44x multiplier like I have done?

setter · 31 Jan 2013 at 22:06

Not yet illuz, baby steps here lol. Finding this a bit trickier than my previous x58 setup, straight in at 4ghz on it with relative ease. 4.2 with a bit of tweaking. The heat jumps quite substantially with ib once the voltage increases.

illuz · 31 Jan 2013 at 22:14

I've noticed that too! Really considering de-lidding my chip but I know I'd be a broken man if I messed that up hah.

setter · 31 Jan 2013 at 22:19

Gonna add another touch of vcore, give bf3 a quick blast. At least p95 running for an hour or so is a sign of some progress.

Dont think id have the cahonies to delid either, i once lapped a q6600 and tbh i was wary of even doing that.
