If I read your sig right... that's under water?

I get better temps than that at this frequency with a slightly higher voltage (1.29) with a Corsair H100... I think you might benefit from re-seating the CPU block and/or re-applying TIM.

Yeah under water with a 240mm rad and EK waterblock.

I'd definitely expect you to be seeing slightly lower temps than me.

Mine isn't a "good" clocker... can't even get 4.7 stable with 1.4V!

Others seem to only need 1.23-1.25V for 4.6 & I need 1.29

Currently running prime 95 small fft's with the following

4.6Ghz
CPU-Z reported voltage of 1.192v
Hottest core is 78 degrees

Looking ok so far?

very low volts for that overclock

try the newer version of Prime though - it stresses the CPU far more - the threads should show AVX

I googled prime 95 64bit avx and that was the one I downloaded from mersenne I thought! Will go look

Blimey, just checking xtremesystems.org and found a good reason for me to get Ivybridge 3570K. I've wondered about how good my TRUE 120 cooler will be, and here is evidence. This guy has good temps on a great overclock.

His rig: MOBO: ASUS MAXIMUS GENE V
CPU: i5-3570K @4,7ghz (1,25 vcore) (cooled by Thermalright Ultra 120 Extreme)
RAM: Corsair Dominator GT DDR3 (2x2GB) @2200Mhz (8-8-6)

Its not stable at lower volts, it is what it is.

WOW seriously it is not stable at something below 1.3v?
That is crazy

Mine needs 1.29 to be fully stable at 4.6ghz (well I use offset +0.70v (or was it +0.070v?

)). It will get through hours of prime, IBT, etc. on lower vaults but as soon as I run a game for a few minutes it blue screens, even though it's not running anywhere near 100% load in them.

Thats the cooler I have, and with its rather unflat base temperatures really are not that great!

What sort of temps do you get and on what system? I've always had low temps well below 50c, but then it's only cooling a dual core AMD. The max temps that guy with the 4.7Ghz O/C seems to be showing is 84c with the TRUE, which is about right from what I've been reading about ivybridge overclocks? No idea though if that's with a lapped or unlapped base.

...

I'd be cautious about that LinX is only showing 64gflops, a 2500K/3570K at 4.7ghz should be getting be getting well over 100gflops with AVX, imo he's either throttling or using an older version of LinX which isn't as stressful.

yeah - these Ivys are odd clockers

I too can be Linx, Prime etc stable - yet firefox will crash out ... or games will crash

I upped volts a bit, PLL and Vcore and setting LLC to Extreme and they went away - I think its to do with non full loads and altering volts - but not sure what it is

ie as the processor is not fully loaded - but loaded enough to go to one of the turbo states - not enough volts are being given to it

Seem to have hit the limit on my 3770K

4.6Ghz @ 1.27v

Prime95 small ffts hitting 85 degrees

I dont think the chip will go any higher. Either a **** chip, or Ivy bridge really is a terrible overclocker

Or if you turn HT off you drop about 10C remembering your never going to have your CPU under 100% load ever anyway.

Buckster · 7 May 2012 at 17:26

ah I'm not sure if the BSODs I'm getting are the CPU after all

before each BSOD I get the a weird pattern of Ai charger warnings (20 of them) in the event log followed by a BSOD

The driver \Driver\AiCharger failed to load for the device PCI\VEN_8086&DEV_1E26&SUBSYS_84CA1043&REV_04\3&11583659&0&E8.

Ollie1132 · 7 May 2012 at 17:27

Oh dear :/ do you know what you have to do to sort it out? :c

G-Sharp · 7 May 2012 at 18:20

Sorry for the noob question, but how do I make the voltage and frequency drop at idle using BIOS? The only reaon I am using the ASUS AI Suite, but I hate that the settings are not saved after a reboot.

hyperst · 7 May 2012 at 18:48

Worth checking your bus speed is not fluctuating too much while you start a game as I should imagine with the gpu kicking in it could make a blue screen if your gpu is unhappy at a higher bus speeds.

MrH · 7 May 2012 at 19:04

4.3GHz, I could go higher but honestly there's no reason to, and my temps are nice at this OC. 30 mins of Prime 95 just for the screenshot, been running BF3 for hours at a time with no issues.

RounD · 7 May 2012 at 19:20

Like the guy above it can do higher, but no reason to and I'm happy with volts, temps and the silence this clock brings. I also only ran Prime for half hour just for the screenie but it did pass an overnight test and has been perfectly stable in all my games and tends to run 10c-15c cooler in games.

mikeym · 7 May 2012 at 19:25

After a bit of tweaking I've got this but will be playing around a lot more in the coming weeks to see whether I can reduce temps / improve clocks. I've had 4.6 stable hitting about 85c max but I'm sure I can improve on those temps or at least get a better oc at the same.

One of the cores seems to be consistently 5-6c hotter under load annoyingly...
