MeltdownPrelude

I have an e6850 CPU that i've been trying to overclock. When i bought it a year ago i read many many many reviews saying that it was the latest epic legend of OCing, many people breaking 4.0 on air.

Im not that ambitions but -


I cant even keep it stable at 3.6. Hell, i cant even run orthos for more then 20 min at 3.2. I cant, for the life of me, figuer out what im doing wrong.

To start, i ran my computer at all stock settings with orthos for 24 hours with no errors just to be sure all my hardware is fine.

i have an MSI 680i mobo and 2gb 800 ram set to 5.5.5.15 it is not linked to my FSB.


Ive take small steps with my voltage from stock settings up to 1.52v and never any higher then that as its listed as unsafe by intel and all other users i read about never had to go higher.

My temps are always perfectly safe, i've never seen it go over 52c even under load. Regardless even at only 3200mgz my computer locks up after 20-30 min of orthos no matter what i set my volt to.

Am i missing something or am i the only poor ******* on the planet to get a dud e6850?

its not a dud E6850 but if you keep cranking up the juice to 1.50 it will be


give us the make and model numbers of your ram sticks

which motherboard exactly do you have ?


download and run cpu-z then give us a screen shot of each tab from within cpu-z


if we had digital pics of each screen in your bios that would also help alot ...... especially the overclock settings in the bios screen

use image shack or similar to post pics

im not at home so i cant get the info rite this minute, but why would my ram matter when its not being overclocked at all and its set to stock settings fully tested? its name brand ram i just dont recal off the top of my head. my mother board is either a MSI pn6 platinum or diamond (i have two computers i dont remember which one has which without looking at them)

i also have a 750watt corsair for my psu

linderman

need to verify you have ram sticks which are compatible for your motherboard .....that is a situation which can be far from a slam dunk!



especially the nvidia chipset motherboards, they are very fussy about memory

MeltdownPrelude

i would have thought that a 24 hour run of orthos would have proved the ram is fine, but ill check the exact info when i get home

linderman

if you had a successful 24 hour run of orthos you are fine

MeltdownPrelude

only at stock CPU FSB settings, overclocking by even just 200mhz (OCing only the CPU not the ram, they can be done seperately) makes my computer freeze after only 10-20 min of orthos.

im just really frustrated having a legendary OC cpu that i cant even boost 200mhz with reasonable stability. Ive looked all over the net, i have never found anyone that didn get it to at least 3.6 yet i fail at 3.2.

Is it maybe because ive had it over a year? i didnt want to OC it when it was new, didnt want to risk any damage. but now that ill be building a new computer in a few months i thought i may as well squeeze every ounce of power out of it that i can.

linderman

ok then (thanks for the added info) we are back at the ram

there is "value" ram which will run at stock settings better it takes a much better slice of ram to overclock with, most likely that is your problem

overclocking requires a capable "team" must have

good mobo / cpu / power supply / ram sticks / cooling if any ONE of those are weak, kiss the overclocking good-bye

MeltdownPrelude

Its Patriot memory and i was mistaken about the 5-5-5-15 its actually 4-4-4-12.

my cpu cooler is a zalman, i think its "9500" or somthing like that.

the mother board is the "diamond" version of the p6n

I have no "bargin" parts, everything i bought i did fairly extensive review research ahead of time.

Any thoughts as to why i cant get a stable OC? I dont understand how ram that isnt being overclocked at all could effect my CPU overclocking. not that i have bad ram, it was like 200buck when i bought it.

oh and my video cards are 9600gt sli

linderman

are you running two sticks of memory or four ?

which bios revision are you running now ?

MeltdownPrelude

two stick of memory now, after i realized regular xp cant read 4 i put the other two in my other computer. My bios version is whatever is stock, i never flashed them. I generally go by the rule that if bios arn't causing a problem, dont muck with em'

linderman

for good overclocking results you will definetly need to update your bios, as long as your use the version which reqiuires a floppy disk or USB stick you will be fine .......flash to the latest non-beta bios

linderman

http://www.msi.com/index.php?func=do...1&prod_no=1168



there is some good updates in there for you, considering bios version 1.2 from 07/2007 added improved support for 1333MHZ cpu's

1.3 is the version I would update to .......follow the instructiuons listed on the bios page >>>>> your motherboard manual will outline the procdure using a floppy disk drive

MeltdownPrelude

my bios are 1.3

MeltdownPrelude

Same results with overclocking, cant get it stable at any speeds over stock.

images are of stock settings. ide like to at least get my computer stable at FSB 1511 (3400mhz) but no matter what i set my CPU voltage too (from stock of +0.00v to +0.1250v) Orthos freezes my computer after 10-20 min.

The CPU-Z picture is with orthos running otherwise my multiplier lowers it self to 6, regardless of eist being disabled (read comment below)

one somewhat separate questions - why is it that with "intel eist" disabled, as you can see, and with my power options set properly, does my idle system reduce my multiplier to "6" and not go to its proper setting of "9" unless there is some load? Disabling EIST *SHOULD* disable that feature but it simply doesn't.

linderman

I remember the 680i chipset doesnt like to run memory above its stated speed ...... so I would use the "unlinked" fsb memory option


set timings to 4-4-4-12

then try again

MeltdownPrelude

its already unlinked as you can see i have it manually at "800" the other tab would show that its at 4-4-4-12 already i just didn't take a screen of it. thought i mentioned it in my origional post - im not overclocking my ram at all

linderman

I am at a loss why you cant get anything out of that set-up ......... the 680i is not a whirl wind overclocker compared to the P35 and P45 chipsets but you should be able to hit 3.4 ghz like a breeze

linderman

have you tried manually sertting your memory voltage to 2.0 volts

and .01 volts to your NB

and add .03 volts to your cpu

linderman

with an aftermarket cooler I would "expect" to hit 3.6ghz stable with that cpu
