View Full Version : E6850 L718A overclocks
looks like a bunch of us who got the first batch of shipments in the US ended up with L718A chips. thought it might be useful to see what kind of results we're getting out of this batch.
L718A190, pack date 6/27/07 - have to admit i am fairly underwhelmed so far. first stabilizing at 9*400=3.6Ghz. chip can survive basic usage at voltages as low as 1.35V but won't stand a chance in a long torture test (dual orthos + 3dmark06 loop + hdspeed). needs about 1.425V before torture tests pasts, and i haven't even had a chance to verify that past about 4 hours yet. so far this could pass for a decent E6700.
gets fairly hot too - core reaches some 58C after hours of torturing, of course that is on air and in closed case, as those are my constraints for this system.
oddly enough it looks like it can stand torture at 9*367=3.3Ghz at nice low voltages e.g. 1.275V, which gives some much better temps. for some reason this thing seems to want exponential increases to voltage past 3.3Ghz. but there is a lot of tweaking still to be done so i won't be writing it off yet.
other results?
Why you are starting another thread? We have many G0 (E6850) threads here ...
i saw at least 6 people on this forum mention that they just received E6850 from batch L718A and it would be useful to see the results, if only for future reference of people buying particular batches of E6850.

i agree, thanks for sharing
In light of these new fsb 1333 chips , we're all categorizing them as g0 and its already well documented that not ALL of them are monster overclocking chips. reporting the batch helps us differentiate
I probably have 1 of these also, ill post results when my e6850 gets here friday
what cooling are you using jpm and where did u buy from?

exactly... honestly what i need from this system is a moderate overclock at low voltage, which is potentially as hard to obtain as an aggressive overclock at high voltage.
cooling is with an ultra-120 extreme. got good contact (both surfaces are fairly flat) with a thin layer of as5, and that is after remounting several times, so i don't think the cooling is holding things back. it's a bigger issue that i've packed this into a lian-li pc-s80 with other silencing equipment, which complicates the air cooling (but did i mention it is very, very quiet?). this is actually a fairly interesting system in terms of design tradeoffs, i'll post photos at one point but first i'd like to get the clocks stabilized... for now, just collecting data.
i bought from priceguidenetwork.com and received it on 6/19. i'm already seeing chips from batches L721A and later, in fact this is the earliest batch i am yet to see codes for on the retail chips.

Do you have different ram to try it on, otherwise try one stick.

So the famed G0 isnt the monster we had hoped for.... still waiting to see further batches of this stepping before I buy into it.

Can somebody please test max fsb even just screenie stable.... Thanks.....
Nice clocks btw guys.....
i will post some more results this weekend, as i've been doing some long torture test burn-ins all week. since i need a stable, quiet, low-heat, closed-case system, i haven't been pushing the higher clocks -- right now it looks like i have a torturable configuration at 8*413=3.3 and 1.28 vcore. i do know that this chip can at least boot into windows at 4 ghz on air, but i'm fairly sure it will need serious volts (>1.5 vcore, 1.55 nb, 1.20 sb, etc) and better cooling (airflow) to survive real torture.

this is what I have got using just "auto" under the cpu voltage so far...I also added 15C to my temps with speedfan:

well i've had a week with this E6850 L718A and i'm warming up a bit to it. with a reasonable amount of effort i can push this to 9*425=3.825ghz on air, with 4gb memory hitting 1020mhz / 5-4-4-12, orthos stable:
http://troud.com/private/bmf-reloaded/bmf2-oc5.png
... but doing so required pumping 1.575V (bios) into the core and 2.15V into the memory, neither of which i am quite excited about doing for a few reasons.
personally i think i will tend to stick with a much cooler configuration at 8*413=3.3ghz @ 1.26V with memory at a 1:1 ratio 825mhz / 5-4-4-12:
http://troud.com/private/bmf-reloaded/bmf2-oc6.png
low voltage has advantages -- i'm actually very satisfied with those temps, considering that this is in closed case on air. less heat means i can afford to reduce fans and airflow, which is a big part of this case being extremely quiet.

not as impressive as i thought these chips would be. If mine clocks the same im selling it for a Q6600 since they are hitting 3,6 on air.

well i'm happy with 4.0 i'm sure i can do 4.2
by the time i'll need a quad i'll get the 8 core cpu:D

well; i reinstalled my 6850 and the temps are now thru the roof (LOL)
1.5v is enuf to push my chip past 85C tjunction and fail dual orthos very quickly.
initial erroneous/low??? temps have all disappeared. I now have ctemp95/94 and speedfan 4.32 and TAT and ASUS probe giving me the SAME readings. (after swapping out my 4300)
currently 1.37V at 32C @ 20C ambient @ IDLE.
now at 450x8 dual orthos ok; tuniq is as tight as it will go.
Dual Orthos takes me to around 68-70C @ LOAD@ 1.4V/1.35droop. - and that is at 20C ambient!!
So my formerly very cool chip is now apparently not so cool - even though the heatsink base does not feel warm at all....all my coretemp type readings are now quite high.
So; this chip still needs very good cooling to achieve its potential.
Otherwise it's obviously got a good FSB potential - I have run it at 500x7 - i seem to reach optimum sandra score at 480x7...@8200MB/s
But i'll need better cooling in summer where ambient is 8-10C higher :eek:
not as impressive as i thought these chips would be. If mine clocks the same im selling it for a Q6600 since they are hitting 3,6 on air.
agreed, at least my chip has not panned out to be the low voltage, low temp, high clocking beast that people were touting.
i am minimally satisfied with my chip, because finding an E6x00 chip that does 3.3ghz at 1.26V on air would not have been a good bet. but if my goal was highest possible clocks, i would be disappointed.
but i am still interested to see what the other results from this and other batches are. intel is binning heavily and i'm sure some lucky people will receive some golden chips, even possibly in this same batch.
seems like these chips want some voltage if you wanna go above 3.6GHz
mines a L719B batch and im currently running 9*400 on water, but only had it on for 1day currently running on orthos for few hrs @home
just wish i had a better memory divider on my mb

Mine is L718A, and same experience, wants too much voltage to be stable beyond 3.6Ghz.

I still believe in G0 and that the US guys got a bad batch initially and that newer ones will do better. I've seen in a swedish forums now 3 users that found max stability on high volts on air at about 4.1~4.2GHz and 4.3~4.4GHz windows clock shots. Stepping L722A186.
hehe its an awsome chip, its Stable in a game at 2 hours atleast at 4.2ghz
so ill take that if i leave it at this setting, it will settle in a little bit more after time.
at first boot i was able to keep it all prime stable at 3680mhz with only 1.34v
seems like im a little lucky guy :)

high volts? how high are we talking about here?
my setup is with 1.375vcore right now, and im sure its not a problem getting over 4.0GHz as long as i bump up the voltage to 1.5
well its high for my 4.1-4.2 i need between 1.65-1.70
its goes easy up to a certain mhz then it goes Boom, and it wont help nomather what you do...i can understand that u can reach 4ghz, that i can do with 1.50 something, it is when higher mhz is reached the difficulty begins :) and which cpu u got, bad or good? :)

infa, to be fair, comparing water to air is apples to oranges. i would hope that you're seeing dramatically better results on water, otherwise there is no reason for water cooling to exist.
ehm, where did i compare water against air cooling? i just told my success with my cpu?
and even if i got water im not getting any higher than a 4.1-4.2 stable clock..maybe its the board, maybe the cpu.
sure i got lower temps then air, but in this case it wont help me that much if i look at people with aircooling.

your sig shows a watercooling setup, is that not the case? water cooling takes heat away better and faster than air and so i would expect to get higher speeds at lower voltages (e.g. 3.6ghz @ 1.34V vs. my 1.45V)... effectively the scale is shifted when the cooling is more effective, we will both probably top out around 1.55-1.6V, but water will hit higher mhz at every step...
yep it is, but i wasnt comparing like that ...or i wasnt thinking of it atleast..heh.
just wrote it , never ment it to be a comparisson or something.
well well.. :)

I got a 6850 yesterday & its a L719B chip! I haven't seen any B chips on these forums yet, it currently running orthos for 3 hoursat 3.7Ghz 1.36V:D will test more though!
I don't think my DFI board likes my PC&P 850SSI PSU because according to smart gaurdian my Vcore dips like mad! 1.42V Idle & dips to 1.36V loaded which in my opinion is crap!

I have been testing my E6850 for a couple of days now (L722A241). Here is what I have found so far.
Highest boot so far 4104 Mhz @1.56 V core 1.548 Load. Stable for playing around surfing the net but not prime stable.
4005 Mhz Same settings as above. not prime stable
3960 Mhz @ 1.53 vcore, 1.52 load. Prime stable for an hour. Core temp 55c
3850 Mhz @ 1.50 vcore, 1.48 load. Prime stable for an hour. Core temp 50c
3600 Mhz @ Auto vcore 1.3??. Prime stable for an hour. Core temp 40c.
So there seems to be a big increase in vcore between 3.6 and 3.8. Doesn't seem worth it to me to push Vcore past 1.50v so I will call mine stable enough for everyday use somwhere between 3.7 and 3.8. I am quite happy I can run at 3.6 on stock voltage and may end up using 3.6 for every day use.
