I'd be happy with 4.7.

Delidding I think equals intels get out of jail free card with the warranty being voided, I'm sure they would love everyone to do it. Therefore the other option being to enjoy as is until out of warranty and save the delidding as something to look forward to later.

Would you recommend de-lidding to someone like me? I mean, someone with at least a half decent chip. Or would you only advise the risk to someone who has little to lose?

I am not going to say whether people should do it or not. I think I am one of the few who managed to stuff up their chip doing it.

All I will say is that, in my case at least, it really wasn't ever worth it to begin with.

And, quite frankly, I don't imagine anyone getting much more than an extra 100MHz, maybe 200, out of the process.

I won't ever do it again, I can tell you that :D

Sadly, seems I am not even getting 4.7 stable on new chip. Hadn't really done much in way of pushing and stability testing since getting it, but have been trrying to play some BF3 last couple of days, and is crashing to desktop.

Wonder if I didn't stuff my board as well :(
 
Actually, this chip isn't mediocre, it's rubbish - looks like I might not get anything over 4.5 stable.

Oh well, I get 30 days to return anything at place I bought it, so think this one is going back...
 
did some accidental experimentation last night (bios update - you can't save your oc settings)

seems memory speed does effect Vcore required ... these with my Samsung memory

1600 1.35V, CPU @ 4.5 - needs 1.225V

2200 1.45V, CPU @ 4.5 - needs 1.285V

quite a difference
 
Is there anyway to turn the igpu completely off? I've been getting blues screens and I suspect it's down to putting clock+volts of the igpu to their min. Doing this reduces load temps by around 5c. I had a week of non-stop solid folding and temps averaged around 70c, now after a blue screen just now I put igpu clocks+volts back to normal and temps going above 75c on full folding load.

system blue screened on a youtube video with hardware acceleration turned off which is why I suspect the igpu, though last blue screen was when I came out of a game, is igpu on the ivy in use then? Event logger after recent blue screens reveal nothing

I had gpu clock down to 400 and volts I think at 0.75 something

I'm stressing my 3770K @ 4.7GHz at the moment and it needs 1.35-1.37 to run AIDA64. I'm thinking my chip isn't that great considering a lot of you seem to be doing 4.5 etc on under 1.3. I wonder if having all 4 dimm slots filled is causing this?
 
Am I right in thinking that to get over 4.3 on 3570k requires setting a cpu core v rather than having this set to auto?

Setting an actual value for cpu core v stops you having low volts when the multiplier backs down when not under load?

What are these offset volts I see people mentioning, I can't see that in msi mobo?

How long on prime blend would be considered stable?
 
Hi, I am struggling to get P95 stable and seem to be encountering infrequent BSODs whilst idling at the desktop, but everything is fine whilst gaming.
It BSODs under prime (small FFTs) after just a few minutes with all workers running still and max core temp of 75*C. I'm currently 15 minutes into stressing with 1.208 vCore

How do these OC settings look? From what I've read this voltage is quite high for 4.3GHz

Multi - 43
BCLK - 100
vCore (load) - 1.200 (1.204 idle)
LLC - Auto

Any help would be appreciated, thanks
 
If you're blue screening I suspect you just need to keep gradually increasing the vcore until it stops. My 3570 isn't a great clocker at all an needs 1.296 for a stable 4.4 ghz. At 1.284 I could run 30 loops in IBT and prime for over 12 hours, yet it wasn't rock solid and would occasionally blue screen.

Happy with that. :)

Hey Freddie. What cooling are you using? My temps get very toasty at just under 1.3v!
 
Currently testing under prime blend as I've found that harder to achieve than small ffs.
Passed a few hours last night before stopping it as I didn't want to chance it overnight until I'd done a long test whilst I can check up on it.

However, what was stable last night wasn't when starting from cold this morning but seemed my mem needed a bit more of a nudge to volts.

Currently testing;

CPU ratio : auto
BCLK : 100
Vdroop / LLC : auto
CPU core v : auto
Core ratio limits : all set to 43

vCore (load) : 1.168 acording to CPU-Z
Temps averaging 64c
2 hours stable so far and no WHEA errors in the event viewer, system log.

Mem running at 2133MHz 1.5680v
 
I usually leave mine running over night and if it's still going in the morning i'll leave it running until I get back from work. If no errors are reported in prime after that have a quick check through Windows system logs for WHEA warnings. If that's all good then a week or so of general use and gaming before being happy.

It may simply be the memory voltage that affects required cpu voltage. This was the case with the 1156 platform. On my i5 750, lowering the memory voltage also allows me to lower the cpu voltage at same speeds.

I remember reading that the difference between cpu and memory voltage should be as small as possible. There was some technical explanation, but it went over my head :)
