Unlucky Haswell CPU?

Its probably nothing much but the Proposed Processor Graphics Voltage drops from 1.000V to 0.500V ? im new at this so was wondering :)

My i7 4770K is at 4.2 atm hope to get it higher but hey ho ,
There is 1 way of making sure you get a better overclocker and that is buy a cpu/mobo combo that has been overclocked before you buy it! but weres the fun in that ? ! lol

Hm not sure. I do have the onboard GFX disabled, might be why, or some powersaving? :)

No, you don't have to be happy about it but accept that you rolled the dice and lost, take it gracefully on the chin like most others would do.

Not, like you have, have a tantrum that even my 3yr old niece would be embarrassed by. :rolleyes:

I have called to cancel my RMA, as I was being petulant/frustrated about the CPU.

Not in a happy place right now, so apologies if I was OTT with my responses to anyone.
 
As a last-ditch attempt, try setting processor cache voltage to 1.180v manually, and give system agent voltage a +0.200v offset in the bios. Knock uncore/cache ratio down a click to 39x, and try vcore at 1.22v.
Looking at your settings, I think you may be overdoing the vcore and your problems could be down to insufficient cache volts.

I may be wrong (probably am...) but worth a shot?

Yeah. I thought I was going the wrong route, as increasing the vcore brought no more stability than leaving it, in fact I dropped from 1.29 to 1.25 and had an evening of BF4 and testing (x42) with only one crash before shutting down. I managed x43 with some stability, so I think you are right, I'll try tonight :D

EDIT: Just to say, following on from your point about the cache volts, I have knocked it down to x33 and 1.180v, as it should (so I understand) eliminate the BSOD 124, possibly related to uncore/Ring(?).

Thats what I've read, but testing at the moment :p

Well, nope, not really. Currently sitting here at:
Multi x 43
VCCIN 2.0
Vcore 1.33
Vring 1.05
Uncore 36
All Cx Power states Disabled (for testing only)
LLC Extreme/Turbo (seems to make little difference to my own stability)

I can happily boot into windows with 4.4, but have no stability when running IETU. Temps are fine with the Be Quiet, idle 33-36, max load 77, so I have headroom. I've avoided going higher with vcore even though my temps are fine, as 1.4 on air seems to be the agreed (so I read) upper limit.

Just have no stability over 4.3 which is annoying as I seem to have room to increase heat/voltage. Vring is the uncore voltage(?), so leaving it low, 36 etc) shouldn't need a bump in voltage, or have I got that completely back to front?

As a side note, easy tune, which I ran for giggles, took me to 4.7 before sanity kicked in, and I uninstalled it ;)

I've read that the whole system affects the overclock, right down to the quality of voltage the psu is giving.

True, I guess I'm limited to 4.3, but that said, as I know it makes it into windows, and performs, other than a stress test, I know it can do 4.4 with some tweaking, so I'll continue ;)
 
I'm surprised no one has pulled you up on double posting mate, if you have something to add before someone else has posted, you need to use the Edit button matey.:D

what gpu do u have ?

Gigabyte Radeon HD 7870

Can get semi-stable at 4.4Mhz but wont fully complete more than 10-15m on AIDA64/ETU. Temps are fine, AIDA64 81c and ETU 77c load temps. Cooler is the Be Quiet Dark Rock Pro 3. Right now, its not cooling, maybe 4.5 would need it, just trying to find the limit. Happy with a stable 4.3, but know it can do 4.4.

Core x 44
Uncores 40 (or less)
vCore 1.35
VCCIN 2.0
Vring 1.1
LLC Extreme
Dram 1.5v @ 1333mhz
C States On

Put Vring to 1.2
Click to expand...

Yeah I did try when you suggested it earlier, but it seemed to make no difference to stability so I was scratching my head :confused:

So, update on current progress. I did up the Vring as you suggested, and am running at the below settings:

4.4MHz - Multiplier x 44
Uncore x 36
Vcore: 1.35
VCCIN: 2.0
VRING: 1.2
LLC: Extreme
K OC Enabled (Can't remember if I had that on Auto before but I enabled it anyway)
C3 Enabled - All other C States Disabled (other than Thermal)
Intel Turbo: Enabled

Temps are quite good on AIDA64/XTU with max peak of 85c under load. I've still got to run more lengthy tests, but is stable at the moment. I'm cool with the temps, but might try to lower the Vcore a little, and is it has to be, drop to x43, but I'll see how it goes today ;)
 
My i5 3570k only does 4.3GHZ @1.35v with constant voltage so I am even worse off than you yet I am not complaining, I haven't been lucky but maybe next time.
 
Out of interest, was this an OEM or retail CPU?

I've found OEM chips from the big retailers that build there own systems to be poor overclockers. I suspect some binning is going on with the OEM chips with the good ones being cherry picked for their OC'd systems.

I had an OEM 4770k that wouldn't boot above 4.3ghz to sold it on ebay and got a retail 4770k and bam, booted into windows @ 5ghz with 5 mins tweaking.

It was Retail.
Happy with 4.4 at the moment. C3 is nice, very low Vcore on idle, and stable at load. Still to OC my memory (sammy green) which I understand from here can OC very high, so that's next on the hit list.

Good to see you're getting somewhere!

I spoke to soon....

BSOD at x44. I also noticed my VID was 1.35, but Vcore was 1.389v, a little to close to 1.4. That said, temps on LinX, XTU and AIDA64 were never more than 85c max after several hours. Anyhoo, opted to try for 43 stable (40 Uncore), and reduce the voltages to as low as I could. What was strange (haswells seem to be very sensitive?), is that it required 1.35v to be stable (one BSOD) at x44, but only 1.27 for x43?.

I think I'm yet to find the right balance between Input, Vring and Core voltages, but I'll keep trying. memory passed SuperPI 32mb at 9-10-10-21 @ 2133 - 1.5v (which i hope is good), but I'm testing with it at 1333 default timings.
