Going for maximum OC

Roverno · 11 Dec 2011 at 07:39

Hi all,

Basically, over the Christmas period i want to try something along the lines of an extreme OC on the rig in my sig. I want to see if i can push to 4.8 or 5.0. For this i will obviously set all fans, and my ALC Vantage on max etc, and i will get a fresh windows install on a different HDD just in case, but i also will need to save my current bios settings and select whats best for a temporary maximum.

Does anybody know the ins and outs of the Ex4 G3 ASRock board and can tell me what settings i might need to enable/disable. Also any tips on what to look out for in the process would be great.

I don't want to be party pooper but your seriously building yourself for a short lived hype. 200MHz is probably negligible.

Whats your vcore at the moment? to get the 4.8GHz?

Roverno · 11 Dec 2011 at 10:31

im not at 4.8 at the moment. Im at 4.6, i havent really changed the voltage much to get to this point, i was just a little lazy and settled at 4.6 once i got it. Didn't really push any limits for attempt to get Vcore as low as possible.

I ran a 2600K at 1.512V, 5Ghz for about 5 months and I didn't notice any degradiation, although temps rarely went above 60C

I'm not saying 1.5V+ is safe, but aslong as your temps are reasonable (below 80C) then for benchmarking I think 1.5V is ok for the Vcore.

Intel state 1.52 max so as long as its cool, should be fine.

Roverno · 11 Dec 2011 at 12:21

Humm, i got quite a lot of head room there then. Or is 1.52V just for 2600k? im on 2500k...

Threepwood · 11 Dec 2011 at 16:43

For the 2500k. Google 2500k and 1.52v

Interesting, Just wondering about load line calibration. It is designed to offset the effects of Vdroop on the core when the current increases? But how do i want to manage this? i think i get 5 levels on asrock ex4 gen3, level1 implies constant while level 5 has a steep gradient. assuming that level 5 allows a large Vdroop while level 1 offsets all voltage drops.

Am i right? or completely wrong?

i dont think Intel have said a safe volt limit

Roverno · 11 Dec 2011 at 18:58

They definately have, if you look on the 2500k they sell on OCUK they give the voltage limit at the bottom of the page. Intel do sometimes say 1.52v but that is just because it is possible, but not necessarily safe.

cjgardens · 11 Dec 2011 at 19:08

any proof of intel saying this?

Roverno · 11 Dec 2011 at 19:16

nope

i have seen it mentioned that some have a stock vid of that.

i would not like to go that high myself. but you hav a 3 year warranty anyway so it doesnt matter to much. just a bit of hastle

For the i5-2500K, i7-2600K and i7-2700K OcUK currently state this on the product page:

- Do not exceed 1.425v core voltage, doing so could limit lifespan of the CPU

^^There is a difference between what 'could' and what 'will'

Here is a link, of a conversation with intel...

A rep there tells the person to look at page 78 of this sandybridge document, where the max is stated at 1.52.

I'm, presuming that is offical enough?

There's also a difference between could and should

In that document Intel State the maximum theoretical VID is 1.52V but I've yet to see a Sandy Bridge processor with a VID anywhere near that.

Roverno · 12 Dec 2011 at 12:27

I will prob just push up the very maximum that OCUK insist is safe then, maybe a little over. I dont need a long term OC on high V, i just wanna see how far mine will go.
