Stable or non stable?
C0 or E0???
Well it is up to your cooling and voltage
For E8400 C0 stable,4.2ghz with reasonable vcore stable is doable and max on air/water should be about 4.8ghz ish for normal chip and load of voltage
For E8400 E0,4.5ghz with reasonable vcore stable is doable and max on air/water should be about 4.9-5ghz,maybe a bit more for normal to decent chip and load of voltage

I've asked so because i've a E8400 @ 4.8GHz daily use,so far still with air cooling only

What vcore & cpu cooler ???

Here's my E7400@3.675Ghz@1.29v

Maximum temperature is quite high when running prime95

Question here..

1.How much wattage differences if i overclock my E8200 from 2.66Ghz to 3.2Ghz
in idle/load without bumping voltage?

2.With overclocked E8200 to 3ghz,does it equal to E8400 power consumption?

Here is my result for E7400@3.72Ghz@1.3v

Passed the 1 hour Prime95 test with maximum temp of 73C!

Was an AMD oc-er before and this is the first time oc-ing Intel. Seems like 4ghz mission is completed today morning and finished stressing just now



Intel C2D E8400 E0 | Gigabyte EP45-UD3R Rev 1.1 | OCZ Reaper 1066 DDRII

For now will be running at this settings before attempting higher clockspeed.

wow! it only needed 1.2V to reach 4Ghz? Impressive!

To be exact its 1.225 in BIOS. Thinking of going undervolt but I think that's fine for me for now. Just passed 1 hour of Orthos blend priority 4 but no SS pulak. Maybe going higher after this.

I think yours can go til 5Ghz..

Try it slowly, and post it here!

Try to change performance level to 7 or so,basically tighter performance level at given FSB net higher bandwidth and lower latency

Sure mate.

can I ask something btw, I never used Memset before, its just for me, a memory monitor, I usually change the timing in bios. So to apply performance level to 7, can I just straightly change it thru Memset and hit apply ? Which one do you suggest me to ?

both BIOS and memset will do... for BIOS, a failed PL settings will result in unable to boot up to BIOS, then need to off on to reset settings... for memset, ur pc will just hang

That explains why my PC hang just now, and everytime reboot after entering windows it'll hang, back to square one

Currently with PL 8 with 2.00D. Everything seems fine with 4.2ghz now at still 1.225v, will do some stressing and keep u guys up to date.

Thanks bro.

i always do the PL setting in bios, as doing it in memset yields me a freezed screen once.
i just can't go into windows with the PL7 i set , and since memset is in the startup sequence,
i only manage to go into windows when i uninstall the memset program.

That was what happening to me just now,after saving the settings and apply after restart, I couldnt go into windows with PL7, and it kept freezing after loading windows, at last I just reset everything in bios, start from scratch. Even PL8 only takes me to 3.8ghz.

Btw here's my latest ss -



Its 1.25v in BIOS, at last I have to increase the vcore from stock. Anyway does anyone know the stock vcore for E8400 ? My bios default is 1.235v. Think this is sweetspot of the proc under low voltage, after this will try out with 2.40B.

Stock should be 1.275 from CoreTemp right?
But VID differs from board to board.

-pWs-

ahhhhhhhh.... at last.... managed to bench wprime and superpi under 4.5ghz @@....

its also my first time able to click start menu>shut down under oc settings HAHAHAHAHAHA

Anyway mates, after we determine our oc settings stable after (doesnt matter Prime95,OCCT, Orthos) few hours of stressing, can we enable CIE,CIA2 and EIST ? Any chance of causing instability ?After enabling back do we have to stress it again just to make sure its safe ?

for C1E, shouldnt be a problem in most cases... mild OC hardly cause problem when C1E is turned on... as for EIST, its automatically disabled once u manually set the vcore and multiplier... EIST is controlled by the OS, u can alter the settings in Power Options... as for CIA2, i don't know what's that -_____-

Added on July 21, 2009, 8:30 amshouldnt bother too much about performance levels i guess... from what i see in benchmarks, they dont give overall performance boost... PL8 @ 450fsb 1500MHz easily pwns PL7 400fsb 1600MHz when i ran everest memory benchmark

btw stock vcore for each proc is generally not the same... but most are within your VID
