zsamz - by your sig you own both atm, how much difference is there in benching between a good 1366 near 5ghz with good rams and your SB setup? Im mainly doing 3D11 and 06 with some vantage and the odd earlier fm.

Cheers.

2200 cas7 stuff is one of the top sets you can have for sb;) love my 2200 cas7 pis
i doubt my cas6 mushkin bbse are better but gonna see next week or so
i know 30h6 sellin a nice set of ocz 2x4gb but forget about warranty ocz needs an invoice
if they had some sort of warranty i woulda bought them already

my 920+e760 is good for 5.0 stable so is my 2600k
but my 920 needs phase cooling .2600k needs water
sandy alot easier to overclock n faster but boring
i love the rex best

Cool, sb may score higher easily but then the fun is over, set the multi/vcore and its over, 1366 has alot more tuning options to try to optimise.

:-/

Okay so i'm not posting picture since i'm not done yet, mainly got questions...

2600k L048A937 D2 Rev
4.3ghz @ 1.28V @ about 68C on 2 cores slightly less on the others.
Prolimatech Megahalems Rev B
P8P67 Deluxe
Gskill Ripjaws 1333 CL7 (7-7-7-21 timings)

I seem to crap out if i go any higher. Is it possible i just REALLY need to bump up Vcore a lot? Also are these temps acceptable on that Vcore for a megahalems(i got 2 fans on it, some... no name and a 140mm noctua)? PLL is currently auto, i have not tried adjusting.

Any suggestions? Or should i just leave it, i am happy with 4.3 :)

enable pll over voltage and give it some more vcore you should be able to do 4.5 with ease

Nice chip Andre:up:

Most if not all SB chip will walled @ +50Mhz and only a few walled @ +99Mhz above its max multi (it will boot up @ +1X above max multi with less than 100.00 BCLK).

thanks bud :up: i will try more but will eat more vcore kinda scary but im on water and i see yours over 1.620 :D
i know it will not boot x55 as it goes back to def bios

Ever tried to calculate costs benching with SB and 1366 ?... with ya 970 you will be rapidly limited by board ( Bclock ) in the 3D department... find a good SB and it will eat ya 1366 for breakfast in benching... only 980 and 990X are still the ideal bench CPUs to due their unlocked multiplier...

Also less LN2 required ( if you want to push ya SB to the max , ideal temp control is must ) eg I have to keep my 5666CPU between -10 and -15°C, otherwise supeprpi32m and 06/Vantage CPU tests will crash, I can bench close to 5600 on the phase... but it's hit and miss then... sometimes it will erratically return me to the desktop as temps are too high or too low at a certain moment...

Indeed a SB CPU can be maxed out within let's say 10-20 minutes from opening the box... 1366 can be more fun to tweak, but so is REX and E8600...

Try 54X and use easy tune to find mhz wall.

I set Vcore 1.54 and LLC10 in bios

yes i use LLC2 same volts on BIOS im not using F4 but F3H wich i find very stable, how is F4 ? good ?
thanks mate !

Yay got my 2600K stable at 4.5GHz 1.35v. I tried 4.8 but i need like 1.44v+ and i'm not really comfortable with it. temps at 4.5 is low 70s and 4.8 is low 80s with a ambient of like 30C+. So far im runing LinX with AVX and getting 101Gflops and it seem all well. im happy. i still would like to hit 4.8GHz stable, what are alright voltages for it 24/7 1.45v?

@m4gg0t

I did a google search on safe voltages for SB and a lot say its only upto 1.380v loaded, some say 1.40 to 1.45v loaded I guess it really depends on the chip.

I've been at 1.45V loaded for 4 months on some of my chips and haven't seen any degradation but I have heard some do degrade pretty quickly at more extreme voltages.

guess no 4.8 for me.

dare not give more Vcore on water, but it has x57,try with an SS next
it's made ​​as a quick test, no fin tun whit mem.............;)

What's the default VID reported as on the first, second and third chips (at 3.4 ghz only).

For everday usage and gaming 4.5 vs 4.8 has no real difference.

great chip dumo !

Will 4.8 with 1.45v be ok for 24/7? i havent tested this yet but i will try later today with the new bios 1409.

Nice chip Dumo. :up:

MicroCenter should add a wing onto the store in your honor.

Im using +0.110v offset under bios to be for 4.8Ghz thats like 1.45v~1.46 actual voltage.

does offset work better then actual voltage? Cause i'm seeing with CPU-Z that my clock do not down clock to 1.6GHz it stays 4.5GHz constantly. I got SB because i wanted 4.8GHZ

After six 2600K (better was a X53) i tried a 2500K
I think its more easy to find a high multi 2500K because this one is the second 2500K that I tried...first one was a X55 also
I will try 2 more 2600K and if I don't find a good one I will give up...the hunting

6th 2600K and I can't find a good one...
