i5-2500K/2600K batch number and o/c results

[makaka]

people do not waste your time with linux or intelburnintest , i was stable at 4.7 ghz with 1.31v 12 h linux and 12 h intelburnintest but i got bsod in less than one hour with prime 2.64

What would you recommend time wise on prime 2.64 to be fully stable!

4 hours would suffice

2600k - batch L042B208 - cooled via chilled water
Below is Areca 1880, 13xR0 Acard 9010 - new 4x core pcm05 WR
5315 is pretty close to max unless a new bios surprises.

What temps are you getting on chilled water with 2600k! Am thinking of going to chilled water!

[Johnny87au]

thanks mate! Have got some more results with even lower Vcore coming! Am getting weird results in temps thou! Core 1 70c Core 2 83c Core 3 80c core 4 78c
Am not sure if my waterblock is on perfect to get a 13c difference from core 2! Has anyone else used this thermal compound IC Diamond 24-Carat!

Is this only something new or have you noticed bumps in vcore from the start? It wouldnt be the TIM you used more like the mounting pressure..

All sorted now cpu block needed to be tighter!

I prefer just gaming, unless you have a second computer to use at the same time.
Especially when your temps are skyrocketing, you can just do a VERY quick run of prime95 (even 30 seconds!) just to make sure that you don't immediately crash. Because if you crash within 5 seconds of launching prime, you actually risk OS corruption if you run other programs....

So are you able to use lower voltages because your temps are real low or because your chip doesn't require more than 1.21v for 5.3Ghz? Also, I thought these chips had a cold bug around 3-7c, did you have any issue with this?

Batch L040B165



Dont laugh at efficiency, was run with W7. I also realize that 2 of the tabs are cpu haha. Been at this 10 hours and 10 beers. XP and cold tomorrow

What are your temps? That is the highest OC Sandy Bridge I've seen yet!

I don't know the answer, but either he got a really golden chip, ot it seasm more likely to be a CPU-z bug, it's not reading the right vCore.

I ran prime blend last night on a 2500K @4500mhz, got an error after 3h42min. This was with 1.270vcore which was 50runs linx+sp1 stable. Should I up the vcore ?

When I get an error in prime it also always seems to be on the last core ?

[Leeghoofd]

My PC is 1 hour prime stable at 4.5 1.285Vcore, lowered it to 1.275, haven't had an issue in any game... if you want it to pass your stability mark, up the vcore one notch to 1.275, otherwise leave it and enjoy the power of SB

Think your pc will be fine for daily ops... read the above :p haven't had a hickup yet...

Good morning guys,
Based on what I've seen so far - for cooling for SB, ideally - I would have the following -
1. For 24/7 - megahalems or super megahalems with good case air flow - with some small luck and skill - 5g stable 24/7
2. For benching - either very good chilled water - down to around 0C (needs to be better than mine) or spring for an SS.
Preferably an SS with some temp adjustability to cope with SB cold problems.

A few lucky folks have found such a good chip that they can reach 55x+ multi's on just aftermarket air.
Based on what we've seen so far, these will likely be only the very lucky (or the very wealthy) few.

edit - For SB I have not noticed lower volts needed when under chilled water.
Part of this is that I'm going after the max score and so operating at high voltage to try to get the max out of it.
The above run was 2x Coolit Boreas in series to a GTZ block, idle was about 16-17C at 1.57v (bios), LLC level 1.
Load temps? I need to check sometime - I'm sure its way up there.

hallo, what is "cpu pll overvoltage" ? Is it dangerous to enable? I enabled it and that made me be able to bench with 52x ratio. plz answer I need to know what it is

Thx

Have just ordered a Hailea Ultra Titan 1500 for chilling my SB and 580GTX hopefully should get better temps but am not going to run to low because of condensation! Nice setup There!

pcmv at 1.61v, 53x multi, ht on, give you an idea of how cool SB runs, this under chilled water, good air probably not much hotter -

[SteveRo]

yes a very good chip, congrats to the Mr. Eldonko, the best I have seen is 57x.

Nice temps at 1.6v! Am running mine at 1.36v 5Ghz at the minute and get about the same temps watercooled! I hope chiller can brings temps down and stay at 5Ghz 1.36 or better!

Get yourself some good mem and score a decent score Great cpu

Thanks buddy

Wasn't benching for Pi just max multi but ye will get round to Pi score one day... I have plenty more interesting things to play with atm.

Sorry that sounds a bit funny but Pi means nothing to me
