ok Guys as the title says ive been doing my first OC today on my UD5H with a i5 3570k. cooling i have is

http://www.overclockers.co.uk/showproduct.php?prodid=WC-041-OE&groupid=962&catid=1532 with one small change i have the black ice radiator 54mm thick version


Crrently im sitting on 4.4ghz with a vcore of 1.176v

and my temps under OCCT avx compatable linpack with 90 percent ram use (out of 8gb) after an hour is

core 0 61
core 1 62
core 2 60
core 3 64

according to HW monitor and the registered highest temps are 65c

is this good?

and what is pll and what should it be set to its on AUTO just now
 
Temps and voltage are good, so you have a bit of headroom there to push higher. For PLL,, lowering this can actually help with oc'ing. 1.65 i have set on mine.

was going to post a picture but i must be using image shack wrong lol

thanks for responding setter if i can get away with auto then im happy as i said im new to over clocking just hoping to get to maybe stable 4.5ghz for stable everyday usage :)

Man these chips do run a lot hotter than 2500K's. I can pull 4.5 stable on mine's with 1.26volts and it never went over 63degree's. And that's on AIR with a Hyper 212!!

You have plenty of headroom there for 4.5 dude. Good work.
 
Looks good, and as occt uses linpack, (same as ibt/Linx) this will generate temps a bit higher than prime 95. 4.5ghz should be doable easily enough, though you may find that you need a higher jump in vcore. I needed an increase to 1.3200v when going for 4.5ghz, 4.4 was ok at 1.2800. Temps rose a little, (76c max) though my chip is a bit of a volt hungry lemon and is air cooled. With watercooling youve got less to worry about with temps.
 
Yeah xdcx its hard to believe 10nm can cause such a jump but when your working in such small scale every bit counts lol i went for water so i could look good and expand later.

it took quite awhile to set up (for me atleast) i leak tested it for over a day lol i think i have most air bubbles out after that time but im told can take up to a week to get every last bit of air out.

Im happy with it so far like my OCing justa few tweaks needed i think lol ty both for being very helpfull :)
 
you need to find your stable cpu voltage at load

then apply it to dvid,loadline calibration affects how much cpu voltage is applied aswell so you need to find the right balance of llc and dvid that = your cpu load voltage

so if "Crrently im sitting on 4.4ghz with a vcore of 1.176v"

id maybe try cpu voltage on normal,medium llc and a negative offset of -0.05 or maybe -0.010v

then stress cpu and see if it uses around 1.176v and adjust dvid if need be

you only really need to use 1.65v cpu pll for overclocks above 4.5ghz imo
 
wow i knew id be in for a tough time thank god for laptops lol im trynig my 4.5ghz oc as we speak i have had to make a huge jump as setter said im at 1.224v im just slowly increaseing if i BSOD till i hit that sweet spot. i got it to boot at 1.2 but its bsoded after about 5 mins on occt ive tryed the tens like 1.210vcore im litterally creeping it up trying to find these sweet spots lol
 
you'll be fine just keep going,for 4.5ghz follow that guide i posted but to increase cpu voltage just add one/two clicks more dvid and retest till your stable rather than set a fixed cpu voltage

turn on all power saving aswell,it wont affect stability
 
no its personal choice,i just don't see the point running full speed/voltages all the time when I can let it scale up n down in speed/voltages depending on what stress I put on the cpu

should see slightly better temps with offset/dvid aswell
 
Wazza is spot on, personal pref but I totally agree with him. There are plenty of guys running fixed voltages in the high 1.2's/1.3's for years with no issue but I personally don't think there are many people out there who need to sit wth their chip running like that totally.

By the way, I see a lot of that for these i5 chips, obviously they are all different but around 4.4/4.5 some chips seem to have a sweet spot and then to even get that .1 above this it requires what seems to be a hefty voltage bump. Some see it as low as 4.2 whereas some guys hit 4.6 on low volts before a bump is needed.

Sounds like you are doing a spot on job anyway and going about it sensibly so you'll have 4.5 probably by now I am sure anyway.

For the record I run 4.4 24/7 but was benching on 4.5 which I had to go into posi offsets. If you are finding you need to bump volts and do this for 4.5 I would stick with that 4.4 clocking for 24/7 stable, it's still a big bump in performance really and will run cooler as you weren't throwing much volts at that. Easier said than done though, I know if I was in your position under water I'd be laughing and clocking higher anyway ha!
 
Yeah i have gotten to 4.5ghz using a vore of 1.224v

Highest core recorded temp wise hit 70c

i do think its a big bump in vc for 100mhz so i may do as you say an d just accept 4.4ghz for less volts
 
I don't thinkso,you need to use very little amounts in dvid,

And choose the right llc level,high llc level and low dvid or a low llc level and high dvid

For 4.5ghz I'd try high llc and +0.010v dvid and take it from there
 
he's using ivybridge chip

paste between internal heatsink and die vs sandybridge soldered internal heatsink

Wow, those temps seem high for water.

My PH-TC14PE can keep my 2500k at 1.37V cooler than that when stress testing.

You cant compare a 2500k to a 3570k in regards to temps. The latter is a hotter running chip, this is due to it using thermal paste between the cores and the integrated heat spreader. The earlier gen intel i series cpu's use solder which dissipates the heat much better. The only way to overcome this is to remove the heatspreader and replace the paste intel used with a better aftermarket brand. Off course though this validates the warranty.
