Well, other people have been making threads detailing their OCs so they can ask questions as they go through it, and I'm pretty new to this so I'll join in with the trend.
Specs: Asus P5B
E6600
Thermalright IFX14
4Gb Geil PC6400 ram (4x1Gb)
Antec 900

I'm getting idle temps of 24C and load of 34C, and thats with the heatsink just mounted, so over the next few weeks apparently it should fall a couple as the AS5 seats itself properly, or whatever it has to do.

I had the CPU running at 280FSB (2.52Ghz) before the cooler, so I'm starting at 300FSB and will be slowly increasing it. But before I start, I wanted to set most things in the BIOS away from 'auto' but there are a few I'm not so sure about.

CPU freq is at 300
Dram freq: DDR2 - 750Mhz
PCI-E freq: 100
PCI clock synch mode: Auto (only option is 33.3Mhz)
Spread spectrum: Auto (Can be enabled or disabled)
Memory Voltage: Auto (1.8 to 2.1V in 0.1 incriments. Geil website states Working Voltage : 1.8-2.2V)
CPU Vcore voltage: Auto (Starrts at 1.7 and falls in 0.125 increments - Which should I start at?)
FSB Termination Voltage: Auto (1.2 to 1.4 in 0.1 increments, and 1.45. Not sure where to start here, either).

I'm not sure where I should start he CPU Vcore at, any help?

Edit: Just tried booting with it all as said above, got a bluescreen with an error in pagefile.sys and a page fault in non paged area, I think it was. Dropping CPU freq to 280 and trying again.
Edit2: Still bluescreens. Going back to default :/
Edit3 (Because I like editing): Back into vista with everything set to auto. The fact that before it used to boot with CPU freq at 280 means I'm doing something wrong. Could it just be the RAM not getting enough juice? I have crash logs, if they will help.

Dont be greedy and give the GeiLs 2.0 or 2.1v, they love it.
Click to expand...

Erm, which is it? Give them the 2.0 or not? :P CPU-Z says they are running at 1.8 at the moment, and thats on auto. I'll disable the Spread spectrum as well, though what is it?

I've read lots of different things about what the stock Vcore should be, as the BIOS didn't seem to indicate it. 1.325 is apparently the default. In CPUz, its reading 1.184V and Core Temp says the VID (I guess its the same thing) is 1.2625
So, tomorrow I'll set it to 1.325, ram to 2.0V and then see if I can push up the FSB without it bluescreening.
 
Right, a couple of things have popped up.

If I set the memory voltage to 2.00V, the value turns red and gets highlighted, 1.9V is ok though. I'm going to boot with it at 1.9V for now. I also did some more reading, that the stock voltage can vary between cores. So, rather than risking setting it too high, I'm going to set it at 1.2625V and see what happens. If it doesn't boot, I'll try upping it a bit.

Edit: Well, its into windows ok with that, no bluescreen. CpuZ says voltage is going between 1.192V and 1.224V, core temp says 1.2625V.
However, this is strange. I've disabled speedstep, and I'm getting some sstrange readings. Core Temp and the intel TAT say I'm running at 2400Mhz. However, CPU-Z (Version 1.44.1) is switching between 1.6Ghz and 2.4Ghz, as the multiplier jumps between x6 and x9. I know thats how the speedstep works, so not sure whats going on :/
Edit2: 280 FSB bluescreened with an IRQ_LESS_THAN_OR_EQUAL, gone down to 270 and it seems fine.
Just tried 275 FSB and it bluescreened, 0x0000007E error, pointing to vx3000.sys which is my webcam driver... I don't see how that could have caused a bluescreen :/
Edit3: And now the 270FSB is bluescreening. DRIVER_IRQ_NOT_LESS_OR_EQUAL pointing to ecache.sys (0x000000D1)
Finaledit: Everythings back to default/auto values and its all working fine again.

Please, any ideas as to why its all failing?

I tried upping the voltage to around 1.3V but it still won't boot up without bluescreening.

I'm guessing its the ram, but I'm still not sure about changing the voltage, since 2V and higher turns the number red, with a dark blue background. I don't know what this means, but it looks bad :3
 
Ok, thanks. I'll set it to 2.1V and see if I can boot with it.

And how is speedstep enabled if I've disabled it in the BIOS?
 
Its not that its not accessible. There is an option for SpeedStep that I can change. I've set it to 'Disabled', but it still throttles the CPU when I'm not using it :P
Its not really a problem, as I'm using my CPU most of the time anyway, but its just a niggle.

Just tried 2.1V on the ram, and its just bluescreened in exactly the same place as before T_T

Thats my BIOS settings. I'm not doing anything stupid there, am I?
 
Ah, not a clue.
Though I'm more interested in somehow managing to overclock rather than disabling speedstep :(
 
Ah, finally. Thanks a ton :D

Set the vcore at 1.3700V
Ram at 600Mhz

Its running 100% load at 40-44C (Though one core is a couple of degrees hotter than the other)
Should I now just keep pushing the FSB up? I know you're supposed to do it in steps of 5, but with around 15C to play with, could I do larger steps, or could this damage the CPU?
Also the voltages seem strange in Vista. Coretemp says the VID is 1.2625 and CPU-Z is reporting 1.296V. Thats almost 1V thats being lost somewhere :/

Thanks again :D
 
Well, I'm not sure if I have speedstep enabled or not. The Intel TAT and Core Temp are just saying 2790Mhz (310FSB). However, CPU-Z is alternating between 1860 (310x6) and 2790 (Core voltage 1.328V at the lower value, 1.288V at the higher value.)
That voltage is rather strange, as apparently its drawing more power when its working than when its idle...

The pics are basically showing that SpeedStep is disabled in the BIOS :P

But as you said, it doesn't really matter, as its going back up when I fold or load up a game. I'm still slightly worried about the voltages its reporting, or is it normal to report more volts when idle?

Edit: Its now sitting at 330FSB in the BIOS (Though 329.8 in windows ¬_¬) giving me 2968Mhz. 35C idle and 48-50C under load. I think I'll stop when I get to around 55C, as 60C is about as hot as you want an E6600 to go, isn't it?

Edit2: 370FSB, 3327Mhz. 40ish Idle, 54 under load. I'll probably go for another 10FSB, and stop there. Though would it be worth trying for 400FSB, as then the ram would be at 800Mhz, or is that not too important?

I kinda feel like a muppet for having been running it at stock for a year :D

Well actually, it was overclocked when I first got it. Then the heatsink fell off and temps rose around 10C after refitting it, so I had to remove the OC.
I had it at 380FSB and it froze while running prime95. would that just be from a lack of voltage as well? If so, I should be able to get up to 400.
 
Okie, I'll try upping the voltages, but the FSB voltage I have at auto. (I assume this is the FSB termination voltage). What should that be set to at default, as my BIOS doesn't tell me what the default/auto values actually are.
Also, sorry for being a nubcake, since I didn't realise what the C1E you were talking about was, even though its right there in my screenshot. Turning it off, and pushing some more volts into it now, here's hoping for the 400FSB

Well, I've been bluescreening with almost every error under the sun (Just had a bad pool header) on 380FSB, with Vcore up to 1.45

The lowest FSB voltage was 1.2 so I've set that to 1.3. Also disabled the C1E.

Vcore now at 1.4625 (And its gone from being a pink colour to red, persumably meaning danger :3 )
Edit: Just had a REGISTRY_ERROR bluescreen. Do I still need more power, or have I hit a ceiling?

I've not managed to boot into windows with it, though I only tried it with 380FSB. Should I keep upping the Vcore all the way to 1.5V, keeping that 380FSB?
 
Will do. Though out of interest how would it be a problem with the memory? Wouldn't something have shown up earlier?
(Now trying 1.3850)
 
Ah, thanks. Made it into Vista on 1.4850 (should have been 1.4 in the prev post) but it BS'ed after a couple of mins. 1.5 is the next stop :3
 
1.5 threw up a bluescreen as well so I turned the PSU off, removed the new 2Gb of ram and turned it on. No signal. replased the graphics card, nothing. replaced the ram, nothing. So I'm posting this with the battery in my hand.

EDIT: Nope, still no signal. There's an LED on the graphics card that flashes when its turned on, and thats still working, so it not completely dead. But I'm not sure what else to do T_T

Edit2: Brain fart moment, everything is ok. Still, I've decided to stick with 1.3875V and 375FSB. Its basically a 1Ghz overclock, and thats enough for the moment. Thanks a million Cob for all of your help :)
