Speed-limiting AND OCing?

simple process.

1. Turn off SpeedStep\ThermalControll

2. Look up your CPU and find out what VCORE its designed for. sit it manually to that number.

3. Up the FSB only by 5 each time, then when it gets unstable back it off 1FSB by 1FSB untill you find the stable overclock.

4. Turn speedstep back on. No need to have your CPu constantly overcloked when you've set a new 'max' for speedstep to go to.

5. proffit!

How did you go, sluthy?

I've managed to get things stable @ 3Ghz by upping the FBS (+0.05v), Northbridge (+0.05) & CPU (1.4v, up from 1.35v) voltages.

OCCT was fine after an hour & Memtest had no errors after about 13 passes, but i'll leave memtest going overnight just to be sure.

I think if things are sweet come morning, i'll leave it at 3Ghz as my temps are fine idle (33-35), but getting up there on heavy load (63).

I'm looking at getting a Thermalright Ultra-120 extreme with a decent fan in prep for summer....i've come down with this overclocking bug alright.

I've been running @ 3GHz (9x333), RAM x2.4 (800), all voltages stock, since yesterday afternoon, and all is well. I ran OCCT for an hour, the highest temp peak was ~58C. I'll eave it this way for a week before I go back and attempt 8x400 again (I might need to up a voltage or two this time).

Should the FSB match the RAM? Like right now, my FSB is 333, powering ram @ 400. Should my FSB be 400 to line up better?

I'll run Memtest while I'm at work this morning and check it at lunchtime.

That's a stupid remark there Master Scythe. The reason is that any overclocking on his board will automatically disable SpeedStep and EIST. You can't enable it back on unless you clock it back to stock speeds.

@ sluthy
To be honest, you don't need to set RAM perfectly at 1:1 but it does help in limiting the RAM limit. About your overclock, just let it burn in at that stage and then try again later.

@ Milano
63C is rather high for a Core 2 Duo. I'd replace whatever you have as a cooler ASAP soon. Then you might be able to push it harder to 3.2-3.4GHz...

Actually, I've got EIST and SpeedStep etc on with OCing at the moment and it works fine. When quiet, the multiplier drops to 6x (2GHz) and ramps up to 9x when I work it.

PS: I thought the multiplier was locked on these models, only unlocked on Xtreme models (QXxxxx etc)? Or can these BIOS's work around that?

Multi's are locked on all but the extreme editions, yes.

I always turn Speedstep/EIST etc off, I don't like the idea of my system constantly changing speed, as long as you have adequate cooling, there's no problem.
Intel CPU's are locked from raising the multiplier, unless you have an Extreme edition....they didn't explain it properly

Okay, I let Memtest86+ v.2.0.1 run for 5hr48min this morning while I was at work, and in that time it racked up...1522 errors. That bad? :O

I've since turned it back down to stock speed. Any ideas?

(Mind you, I don't think I've ever run a memtest on this, my old one or any other PC that didn't have at least some errors.)

1522! That's shocking. DDR800 RAM right?

That's only during OCCT stress testing though. Besides, aren't these C2D chips meant to be able to tolerate anything below 70C??? (they're sitting at 33-34 now btw).

When does EIST actually kick in? I mean, lets say i'm in windows, loading a bloaty program like Photoshop, will EIST enable there, speeding up the load time? Or will it only enable during more extended demand periods, like in games?

Yeah, 2x PQA 2x1GB DDR800 from MSY. I've turned it back to stock speeds and I'll run Memtest overnight.

EIST slows down or clocks down the CPU when it is in idle. It's disabled when you load up something that will load the CPU such as Photoshop, Cinebench, games and the like.

That's a stupid remark there sora3.

Unless this is the only gigabyte motherboard to do this, then you are plain wrong.
It will still underclock when idle etc.

Overclocking then turning thermal\power mangement back on simply sets a new 'max speed' when the system needs it.

prove me wrong, and the 3 PCs i have in my bedroom alone running gigabyte boards will apologise.

Yesterday, after running the first couple of tests:

This morning, after an all-nighter:
http://s322.photobucket.com/albums/nn414/sluthy85/?action=view&current=09092008001.jpg

It appears to be one particular bit giving me errors over and over. Is that right?

I wouldn't know - I always turn it off. never had it running on any of my comps.

Does that screen indicate that there is only one bit at fault giving me the same errors over and over?
