***The Official Wolfdale 8200/8400/8500 Overclocking Thread ***

my system at present.
notice the DRAM:FSB ratio

how do i drop this?

Urm it will be in the bios somewhere (on my p35 board its in with the fsb controls as ram timing auto (or 1:1)) just have a peer in some of the options that relate to ram and an option being auto (or 10:8 as everest points out)

Edit: just seen the bios picture on the o.c. phase select put it on something like manual then down to cpuclock vs memory speed should be the one you need to switch to 1:1 (or something similar) instead of auto

the only options it gives me are:
AUTO
1:2
1:2.4
1:2.5
1:3
1:3.3
1:4

mine is set on 1:2.5 to get my ram @ 1000mhz

how long do you recomend running either for?
i've got Prime (free version) on my pc currently

Most people suggest an 8 hour run of small FFTs to check that your CPU is stable, you can run blend for the same amount of time to test for overall system stability too if you can be bothered :D

My latest effort is in my sig, vcore is 1.29v in the BIOS, think I'll try for 3.8GHz next.

For a first time not too bad......hopefully:) Think I'll leave it there for now. Not really much point in pushing it further is there?

Set voltage to manual in bios and my core voltage dropped by a fair bit. Probably should run Orthos for longer than 50 odd minutes but cba right now.

Just got my e8400 the other day & here what Ive managed so far




Vid is set @ 1.2v bios - I think core temp is a bit off though cos my case is ice cool (all air cooling) - real temp is showing about 12 deg c less than core temp?

Currently benching @ 4050Mhz - gonna give it a few hours yet....

I just got an 8400 and despite my better judgement can't resist giving it a push. Can't find any results in here with a 965 chipset, any idea what to expect? 4GB XMS 6400 on an Asus Commando on stock air at the moment. Won't get time to build up the new rig till the weekend.

That's on an Asus P5K Vanilla (pencil mod), with 2x2GB OCZ Platinum + 2x1GB GeIL Black Dragon (both PC2-8500).

Running 1.475v in bios, which gives 1.45v idle, and 1.41-1.42v load (without pencil mod would give 1.37v load).

I simply can't get it stable at 440FSB because of vdroop, it needs at least 1.42v under load, but it keeps dropping down to 1.41v; and I don't want to raise the bios voltage any higher as I'm already hitting 1.45v idle - I think I need to buy a harder pencil for the mod :P

Temps go up to 85C load, but I'm running on air (might get a better cooler and reset it better, or lap the CPU).

Have you tried upping any of the other voltages i.e. VTT, MCH, ICH?
 
Got rid of my 2GB of GeIL RAM (so running only 4GB OCZ now), and am getting some slightly better results now, still not 100% sorted the new OC, so will post about it later once I've settled it a bit more - currently stable at 442FSB, but crashes within 2 min on OCCT at 445FSB :(.
 
i've not been able to get above 3.7 stable yet. i've clocked upto 3.9 but wasn't stable.

should i be happy running just 3.7 or round it up to 3.8?

i'm connecting up my new PSU tonight (Corsair TX650w) so i may see a more stable overclock compared to the COLORSit 600U 600W i have currently (i know i know it's rubbish which is why i've changed it :p)
 
Depends what voltage you are prepared to push though it really, I'm running 1.46/1.44v now, and will not push it higher, so it's a matter of me finding the max OC I can run at this :)

CPU VID: 1.15V

On a MSI P35 Neo2 FR with 1.325v(Bios),this shoots down to 1.296v under load.

Temps seem fine at about 55-57`c under load.

All in all im really pleased with the E8400, a hell of a lot faster than my old X2 3800 + :p
