E8500 OFICIAL O/C THREAD!

This was giving to me by AndyOclock - thanks again.
this gives me 3.60GHz

and setting CPU VTT to 1.22
and PTT to 1.50 but have not got round to doing it yet.

E8400
VID 1.225
C0

4Ghz with 1.3v in bios. Quite a huge vdroop though under load.

Temps have dropped quite well since the AC5 has had many hours to settle in. Was hitting 68c even after 5 mins of prime. Ambient temp is the same as before (22c). CPU is cooled with just an Akasa 965. Not a bad little cooler for heatsink & 92mm fan. :)

GURUSAN i c you have nice clocking!
want to push mine as far as it can go!

is your stable?
which cooling u've got?
is speed between 4 and 4.6ghz differs a lot?
 
Yeah it's stable, I'm under watercooling but this particular chip seems to run very cool and I'm not using a lot of voltage (1.42V load) so I think it could be cooled under air at these clocks fine.

And nope, the difference between 4 and 4.6ghz is not really noticeable at all except for in benchmarks :) I just hate wasted potential....for example I never understand people who buy E8600s and then clock them to 4ghz at 1.18V or something. I mean WTF is the point in that?
 
You think you can go to 4.8GHz?

Also, which games you playing right now that are using up the whole cpu or core?
 
4.8Ghz ... not sure with my stepping C0, E0 i sbetter, but do not know how far it should go!
saw on youtube 4.8ghz!

GTA V i have heard can't run on P4, so it needs Dual core!

Click to expand...

so i guees there is no point if i won't c difference in performance to go to 4.5ghz?

personally me, thinking that i should drop to 3.8ghz as no difference at all with 4Ghz!

3.8ghz more stable...
 
for some reason i need about 1.29v just to get my e8400 stable at 3.6ghz (c0 stepping)

+ my bios cpu voltage selection seems a bit inaccurate so i dont want to move my clock
 
with my 3.8Ghz (e8500,CO) no problem, almost everything on AUTO!

but 4ghz still not stable after couple of days, raised CPU Volt to 1.4V in bios (so far so good) , in CPU-Z showing 1.37....-1.38V.
 
If none of you guys see difference in those high oc's, just get a Q6600 and overclock it to 3825MHz (on air) and you will see a difference then. For example with games like GTA 4 use more than 2 cores. I think there is going to be lots of new games coming out that will be using more than 2 cores soon. Alan Wake I heard will be, looking forward to that :)

Also you benefit a lot when you decide to transcode something or decode and stuff :)
 
I've had a Q9650 at 4.4ghz and did not see a difference between an E8500 at 4ghz in any game I play.
Q6600 is just a step backwards in my opinion....and I don't play GTA4...I've never understood the GTA games, I've always found them extremely repetitive and boring, very unsatisfying.

By the time there are actually some good games showing significant real-world benefits from Quads, I will probably have upgraded to either i7 or Deneb.
 
If all you do is gaming then yeah maybe. But then again, I dont see how its a step back when you dont use the extra mhz. I feel like if I went to dual core and got 4.6GHz it would be a step back for me. I mean I dont plan on upgrading for at least 1 year, maybe 2. So Quad is better of in that case ;)
 
Got my 8500C0 at 4.2 running a 440FSB with 1.45v... Not sure whats holding me back at the moment, but any higher becomes unstable... Motherboard definately has the ability to go faster, need some more tweaking...

Any way to dump my bios settings so I can post them?
