Help OCing my E6600- got 3.6 can i go higher?

AFK_Matrix · 4 Apr 2007 at 21:17

Hi,

Ok I am overclocking the system in my sig. I have got it stable on 30mins of OCCT at 3.6ghz @ 1.47v on water.

BIOS settings for 3.6:

Vcore - 1.4 +100mv (no pencil mod done yet)
Memory Volts - 2.259v
NB Core - 1.563v

Mem Mhz is 400 (shows 800 in my bios)
FSB - 1600
Multi - 9

Temps - 25 idle 35 loaded

Now I have tried upping the fsb to 1700 and upping the vcore to 1.43 (which is showing as 1.5v in windows) and I can get into windows but it instantly fails super pi 1m. So would the pencil mod i can do on my P5N-E be worth doing? Or am I not gonna get over 3.6Ghz?

I would say there is more in that cpu. Couple of points:

1. Your temp seems to be VERY good - is that taken with TAT? If so you definatley have room for further vcore.

2. Increase the vcore a little more. If you are brave then upto 1.6 for benchmarking although some are uncomfortable using that much for 24/7 it is (imo) safe for a few benchmarking runs to see if its vcore that holding you back.

3. Slacken your timings/lower your bandwidth on your memory. If windows BSOD then its 'usually' memory thats the problem - if it reboots itself then its 'usually' vcore thats the problem when under load.

4. 3.6 is an average clock for an E6600 so be happy with it. Getting it higher is luck of the draw and this usually takes a bit more vcore that dosn't scale like it did previously.

5. Well done

Failing SuperPI is more usually means a RAM error than a CPU error - but not always. But I'm also a little jealous: my E6600 is at 3.6, but it needs 1.475V to stay there.

Thanks for the advise W3bbo.

For temps I used the following programs as TAT refuses to work for me:

Coretemp
Speedfan
Everest Home
PC Wizard 2007
Asus PC Probe 2

All of them were around the 35 odd mark when under load, think it hit a max of 37 of one of the programs.

Will try pushing the vcore up a little more, would upping the NB voltage to 1.7 help as the NB is under water too?

As for memory I set the timings to auto so will change them manually. Any advise on what timings to use, kind of not sure on the whole memory overclocking thing

.

And when i first went to 3.8ghz i didn't change the volts and it froze at the XP load screen, so upped the volts very slightly. I got into windows but it blue screened, upped the volts some more and it froze in XP. Finally upped the volts to 1.5 and it failed Super Pi 1m.

So I am gonna play with the memory and also do the pencil mod tonight.

They are seriously low temps.

What is your room temp?

Not exactly sure as i don't have a thermometer. But its not hot or anything just at a comfortable amount. I can't see all those programs reporting it wrong can you?

Well I do have the side of the case off, but then that shouldn't do too much should it as im on water?

Will double check tonight.

Cupra · 5 Apr 2007 at 21:36

i can get 4.1ghz on my cpu but its running hot on orthos then crashes so with water you have a good chance of getting that stable witht he temps you have.. at 3.6 im @ 58load

AFK_Matrix · 5 Apr 2007 at 21:42

Well i spoke a little too soon lol. Seems Orthos stress the CPU a lot more than OCCT. I have posted a screenshot in the motherboard sectin under the ASUS P5N-E official thread here:

http://forums.overclockers.co.uk/showthread.php?p=9071952#post9071952

As you can see in that screenshot my Vcore is very high, so I have lowered it to 1.4 with no +100mv and at 3.6 orthos has gone 5mins without crashing where as before the pencil mod it lasted all of 30 sec if i was lucky. So I am very happy indeed

Just noticed that your memory is 5300, while it is a good set I would be wary of pushing it further than 800 (6400) speeds. Run memtest to test your memory. Usually tests 5 and 8 will throw up errors run a couple of full rounds to be sure it isn't the memory that is holding you back.

If it's the D9 Ballistix they'll be fine. Mine does 528mhz 1:1 @ 10-4-4-4 perfectly fine with 0.25v increase.

Listen to w3bbo he nearly knows as much as me.

So I echo his post

I have forgotten to mention I am running the memory unlinked at the moment, would this thus not be affecting the clock or would it?

w3bbo · 5 Apr 2007 at 22:17

If you are running it unlinked and at its spec speeds then it shouldn't interfere with your overclock, however it is best to run memtest to be sure m8, then you can take memory out of the equation

AFK_Matrix · 6 Apr 2007 at 00:59

Ok, tested my ram for 20mins in memtest and got no errors at all.

I have done 25 odd mins of orthos at 3.8 and so far so good, gonna run orthos over night and see if its properly stable.

Here is a screenshot:

And the BIOS settings:

Vcore = 1.45 + 100mv
Memory Volts = 2.353
NB Volts = 1.563

FSB = 1700
Multiplyer = 9
Memory DDR = 800 (this is unlinked)
Memory Timings = 4,4,4,12
Memory CMD = auto

So would this overclock be ok to run 24/7 (only if it passes orthos of course) or would it be better to take it back to 3.6 which i can do on less volts?

w3bbo · 6 Apr 2007 at 06:45

If you are happy running at that vcore m8 then it looks ok to me for 24/7 (orthos/3d mark pending). It is now at its max limit that intel recommend for vcore (1.55iirc?).

Applying extra voltage always has its dangers and will shorten the life of the cpu - by how much nobody knows, but if it cuts its life expectancy in half then it is still good for 5 yrs+ by which time it will be a dinosaur in comparison.

You can now start pushing the memory a little more now the cpu is stable.

Well done

Basic law of overclocking: just because yours does, doesn't mean his will. Every system is different.

Are you getting confused about the +100mV? The two settings are AUTO and +100mV. On AUTO, the system applies that 100mV as and when it sees fit. With the +100mV option selected you always get it.

Try 1.375+100mV or 1.4+100mV as now you've pencil modded it, you don't need the extra 100mV to cover the Vdroop.

I know, the D9 5300's have consistantly shown to be excellent performers way above spec and with very tight timings tho. My point was don't think of X being the limiting factor even if the idea seems ridiculous as you never know til u try

AFK_Matrix · 6 Apr 2007 at 16:13

Well I am orthos stable at 3.8

and the max temp was 50c underload.

Heres a screenshot:

One strange thing though, when i stopped orthos CPUZ showed that my multiplier had dropped to 6?? It even showed this in the BIOS when I reset, how comes this changed by itself?

Heres a screenshot:

Gonna see if i can get the volts lower although orthos was failing with lower volts, and it did BSOD so I have actually upped the memory volts and slackened the timings so will have a play with that too.

Thanks for all your help though guys, I am one happy lady now

netby · 6 Apr 2007 at 17:28

nice overclock mate
congrt.
3.8Ghz Orthos stable is a lot

but 1.6Vcore is not for me (chicken)

ballistix PC2 5300 should be ok at 400 mhz ( DDR2 800) at 12-4-4-4 with 2.2Vdimm

seems the cpu multiplier is not locked in bios- it should be 9 not 6 (6 is min,9 max)
you should have a option to lock it to 9( max) in bios
