8400 @3.6 but wants 4.0

[bk2life]

oh and i made a mistake, my memory is
Kingston HyperX 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory

i have 2 sticks.
from what i have read, up the voltage to 2.2 and set them @ 1066 with timings of 5-5-5-15-23 2t

i tried that, system wouldnt boot, only in safe mode.
i dropped 1066 to 1000 and changed timings back to stock, and comp booted.

although icant reproduce any of these numbers, and "stock 5-5-5-15" settings arent working on my board. im @ 8-8-8-24 right now. if i try to change them, i boot into safe mode.

Lets load up some GPU folding and get you on the board. I would like to see a 3D Mark 06 score in SLI from the thing....

(if these temps are accurate?)

Real Temp is the most accurate for reading your 45nm core temps & I would use that to gage if you are in the safe zone on your temps.
The CPU temps will only be slightly less than the core temps at full load.
Mine are just 4F off of what the cores are while under full loaded.

There is no stead and fast rules when it comes to OCing a system.
Each & every single system will be different with what it takes to OC it even if they are exactly alike!
So one might be able to clock higher than the next with his system setup than the guy next to him. That's just the way it is.

There's also variables to consider like what components were used in the build...
Like Powersupply, motherboard, memory, make and date of manufacture of the chip all come into play.

So just work with your system & find out what it can do.
So yours needs more vcore, so be it...

Rich has the same exact system I have, but it takes more vcore for him to get his system stable at higher clocks & thats just the way it is.

Memory timings are going to take a bit more to get them right.
Personally I wouldn't have gone with Kingston memory for a high performance system at all.

Did you set your memory divider to 1:1 or Lock them so that they aren't being overclocked with the system?
If they're already clocked pretty high then you are going to have to add a lot more voltage to them to get the timings tight.

Also, my personal opinion is you'd be better off with Corsair, Transcend, G skill, OCz, etc for a high performance system.
These will work with you better on setting timings & not fight with you so much as they are designed for this.

So if you want to stay with the Kingston, up the volts to get them stable for the tighter timings.
Since I don't know the specs on that memory I don't know how much voltage they can take so you'll need to look that up.

When running prime you will need to run an instance on each core or download a multi-core version. |MG| Prime95 25.7

You might want to play with FSB voltage (vtt) and GTL reference voltages, 58% - 61% will be the area to play in with a dual core.

Here is the pics i took of the before and after

Very nice....

[Daniel ~]

Things seem to be going well here! ":O}

I just wanted to say Welcome home and Back to life. Enjoy your Reincarnation as an Overclocker! ":O}

Very punny Dan.....

[bk2life]

yeh a bit cheesy, but its ok.

been working the past couple of days, so i have not played with ram timings or anthing else.

computer has been working really nice.

i can really see a difference from 3.0 ghz to 3.9 ghz in speed of my programs.

im not sure how much of a difference Oc ram will make, but when i get time i will try again.

[Samuknow]

Over Clocking the ram has little difference. The timings will make a better difference.

[bk2life]

yes the RAM timings is what i meant.

i try to change them and my computer wont boot. i look up the specs, and the website says they shoul dbe at 1066mhz and 5-5-5-15 in stock trim.

mine boots up at 800mhz, and like 6-8-8-23.

i was able to up the speed to 1000mhz, but any more and it wont boot at all. on the rams website it also shows 2.2 volts, and that is what i set mine to to get the 1000mhz.

also if i up my fsb to get 4.005mhz i have to up my voltage from 1.32vcore to 1.400 for the computer to be "stable" on prime95

to me that seems like a high jump in voltage to go from 3.89ghz to 4.0ghz

i read all sorts of "reviews" of poeple gettin 4.0 all the way up to 4.5 with lower vcores than i have ever ran.

[bk2life]

in this pic you can see my voltages, and my cpu usage in speedfan.

my zune program playing music, uploading files to my server, photoshopCS3 running in the background, prime95 running torture test, Microsoft outlook downloading email, i tried to get as much running as possible to fully stress out the cpu, and had no hickups.

not even noticing a slowed down system, music never missed a beat, and temps maxed at 60c at the highest reading.

does this look good overall to the master Oc'ers in here?

if these numbers look good, i would like to next get into messing with the ram timings.

thanks for all the help from you guys....

[bk2life]

13 hours 34 mins on prime95.

max temp at 59-60c load
40-41c idle

It's not uncommon going from one clock speed to another higher one that you have to really up the vcore for it to be stable.
I have the exact same thing with my system.
Right now I'm at default vcore @ 3.30GHz, but to get to 3.40GHz I have to increase my vcore from 1.2700v to 1.4000v.

There will be the rare case when someone gest a very good CPU that will be stable at higher speeds, but these are few & far between & usually hand picked.
From what I've read on the E8400 1.4000v is very common for 4GHz.
Another thing you have to keep in mind.
Even though your bios is reporting that your vcore is at 1.4000v doesn't mean it really is. Most of the time it will be much lower than that because of vdroop.
When I have mine set at 1.4120v it's actually running at 1.3480v because of vdroop.

Lastly, I've found through a LOT of testing & benchmarking the best way to get the most throughput on a NB system is to have your FSB as high as it can run. You can OC your memory to the sky, but if your FSB isn't running fast enough to process the information & move it along it's not going to do you any good at all & most of the time actually will Hurt the performance of your system!
Now, if you can get the timings tighter on your memory this will help on throughput. But some memory doesn't like to cooperate with you at higher speeds even though it's suppose to run at those speeds.
Once my OC hits a certain point with 4gigs installed it becomes impossible for me to keep the 4-4-4-12 timings no matter how much voltage I run to them!
It's because of the added noise & crosstalk between the memory modules & this causes errors.
That's why it's always best to run 2x2Gb dimms cfg instead of 4x1Gb dimms like I have. But for $20 a pair I couldn't resist.

So if you are happy with the speed you're at now, then don't give it more volts to get it any faster as this will create more heat.
Your temps a very good but I think your at the "comfortable" limit for your Zalman cooler as you got the 9500 instead of the 9700 which would have given you more heat dissipation.
If you push it higher it's going to be a bit on the hot side, too hot for my liking but that's just me...

[bk2life]

which air cooler is considered the bes for disspating heat?

when i built this machine, i saw zalman, and since reading i remembered the name, but i didnt know (at the time) the 95 and 97 series.

i have no problems switching to a new cooler, and noise isnt a big concern either.

i see some of these other machines running cooler and lower volts then mine, an me being inexpereinced, im "playing and learning" as i go on what is good, and what is better.

the voltage doesnt bother me much, i have read 1.5 and 1.6 and these chips are still alive, so the 1.4 for mine is fine with me.

but i do know electronics, and heat=death.

also i am considering water cooling, as i live in arizona (desert) and i have a few fans on my 900 case, and its pretty noisey now.
if i switch to water i could get rid of several fans and be quite a bit quiter, and alot cooler on the heat index..

[MUff1N]

So I gather you're living down in the Valley.
I'm up in the cool air of Payson.
Nights are getting very cool now & we've already had temps in the lower 20's here.
We have 2 other members here that live in the valley as well, one in Tempe & the other in Glendale.

As far as cooling with air, for the price the Zalman CNPS9700 is a good buy at the egg. There are other's too that are much bigger & will cool even better but if you're going that route you might as well go to water cooling.

The lower temps you are seeing here is on water so they can tell you a good WC system or get you setup with the right stuff.
Then you can OC that puppy up to 4.7GHz...or higher!

yeah im in glendale also!!

what is the guys name, or maybe have him pm me

low 20s yuck

i had to deal with -19s last year in afghanistan that was major yuck!!

ccperf721p is the one that lives in Glendale.

Now that I've been up here for the last 4 years I kinda like the cold & my computer loves it!
I hated the heat down in the valley. I lived & worked there most of my life.
I can always put more cloths on to stay warm.
Besides my backyard basically is 3 Trout lakes that I go fishing in all the time. Last year my best Trout was 7 1/2 Lbs.
