what batch do you have?
Printable View
mine needed 1.23v for 4257MHz.thats why i think you have got a great one on your hands.
whats the batch number and vid?

and 4124 with stock volts.

My trusty ol' C0 E8400 made it to 4.82Ghz today. I think i may have had the voltage a little higher than what it needed. I think it was the ram and/or the NB making it unstable.
It was 1.58v under load.

I get 4.0 stable at 1.248v.. not too bad for a C0 :p:
Hey guys,
I am just reporting here::
For all those wondering about lifetime of overclocking etc.
I have an E8500 C0 Overclocked to 4.250Ghz, @ 1.45Volts, down to 1.42with vdroop.
Temperature range is from 30C to 50C.
So, the CPU has lasted me for over 1 year now, running 24/7 stable. So
Will your E8500/E8400 last for more than a year on 1.45V? Yes it will!
I am jealous you guys. Damn NICE overclocks. 1.25V @ 4.25Ghz!!! Thats insane. At 1.45V i bet u can get close to 5Ghz, 24/7 stable clock!!!
I am thinking if I should sell my C0, and go for a E8500 E0! :D get like 5Ghz 24/7 clock :D
what fpo/batch and what vid is it?
Also ... here is my new e8400 fpo Q842A (my EP45-UD3P says vid 1.200 but Biostar runs it default with 1.144Volts hadn't had time yet to try clocking it on the Biostar) :D

EDIT: And a question. What do you think about a combination of this water cooling components:EK Supreme + Magicool 240mm Extreme + 2 Scythe Ultra Kaze 120mm 38mm 2000rpm + EK flexible tube + black metal fittings + Laing DDC-1T PRO (modded to Ultra) + rezervoir EK DDC X-RES 100 + aditiv Feser Base Corrosion blocker? Is it a good one? Is compatible with Gigabyte EP45-UD3P and/or Biostar Tpower I45 ? (these are the mobos I have at home right now ... must try Biostar and see how it compares with UD3P)
Thank you,
Florin

Great vcore for 4250mhz.
^ great chip :eek:
my E8400 requires 1.18~ real under load for 3.9 (Stock, VID is 1.212)
1.19-1.20 for 4GHz
1.32~ for 4.3~ :mad:

what max volt can i go with my e8500 c0 for 24/7 ?
thanks

I don't try with less vcore, but this motherboard ( DFI UT T3RS ) is strange, she doesn't like low vcores :lol:
What batch of E8400 should I go with?
I got a choice of Q844 OR Q843.
Which one will OC better ?? Thx
Hey guys can u tell me your batches/Frequency/Voltage?
I got a choice right now, E8400 E0, Q844 batch or Q843
Which one should I buy?
OK,.. so I went and bought the E8400 E0, Q843B035.
Let me tell you, it performs almost the same as my older E8500 C0.
I got the f**king worst E0 ever created.
Right now, it fails at 490x9(4.4Ghz) @ 1.36 Volts, and needed 1.33Volts for 4.190Ghz. Now that is messed up!!!!!!!.
at 4.4Ghz its fails orthos after about 10 mins, Here are my full configs:
CPU Voltage: 1.360V
Northbridge/SB Voltage: 1.360
DDR Voltage: 2.2V
FSB: 1.3V
CPU Core1 GTL Ref Voltage: 0.67*VTT
CPU Core2 GTL Reg Voltage: 0.69*VTT
MCH GTL Ref Voltage: 0.67*VTT
CPU PLL Voltage: 1.7V
If you think these are too high, I also tried the lower voltages and still didnt work.
My mobo: Biostar Tpower i45
Mem: OCZ Reaper HPC PC8500 2GB
Can you guys tell me what the F**K is going on? I mean all the other E0s in this thread run very nice on low Voltages, and the Q843 Batches are good too.
Edit::: I also loosened up my memory (looser than a magicians sleeve actually, 7-8-8-18(5-5-5-15 stock)..
help be4 i explode for wasting $200 for this POS.
Thanks
1.57PPL ? isnt the safe limit for that at 1.450 for 45nm ?
default is 1.5v
Mine is at 1.54v since always.
K some facts : you really think you can get away with a mere 0.03Vcore increase to go from 4.2 to 4.5 ?
Why don't you try to stabilise 500FSB first with eg 8 multi. Those voltages you are pumping through the NB and CPU seem way out of control... Did you verify the voltage outputs via a DMM. Or are these the bios voltages you put in ?
Which Orthos test does it fail ? Blend, Small or large ?
First determine the Vcore via Small FFT , then work on the rams later...
You are going too fast and are wasting maybe a perfectly okayish CPU by just pumping volts. More isn't always better. Each board/CPU needs a certain combination of values to work, just upping one setting is not always enough...
Also did you copy a template of someone ? Sometimes that doesn't work at all... ; GTL tweaking and co is very CPU, Mobo, RAM dependant... try 3 the same boards and they all might need diferent settings
I never really worked with the biostar as my board smoked from day 2 at light load... I immediately sold the RMA...
I would start from zero , use 8 multi and slowly work ya way up on the FSB... else you will end up to be a very frustrated user... it could be ya CPU is a pos, but the voltages I see here are totally out of bounce...
hmmm for me ORTHOS With Priority 1 is nothing!!!
Hi, it's my first post on XS ;)
Anybody have E8400 Q840? It's good batch?
Hi there? Did you disable your Epu-6 engine(Asus P5Q mobo), before you oced e8400?
OK so: I tried everything from scratch at 8x multiplier, and voltage that is 0.025+ above stock, because If i leave it at auto, i dunno what voltage is gunna end up. Screenie::http://xs942.xs.to/xs942/09325/dsc049482870.jpg
So, with these minimal voltage increase I got up to FSB of 463mhz. At this FSB, i pass orthos CPU stress and the gromacs core. When I do the blend and ram test, fails after couple of seconds.
What should I do from here?
