E8400 and an overclocking newbie

post #1 of 8
Thread Starter 
I built this computer a long time ago and in the past never bothered to overclock it much (I think I stopped at 3.4ghz). I got bored of it and didn't touch the computer much for over a year and just a couple days ago got bored and decided to give it all a shot. I followed an overclock "guide" I found somewhere about my combo and matched a bunch of settings in the BIOS as a starting point but I want to make sure its all safe, so I was hoping I could get some confirmation on a few things.

My hardware:
Antec 1200 (WAY TOO BIG FOR WHAT I WANT)
ASUS P5Q Pro
C2D e8400 @ 4,005MHz
Scyth ninja heatsink (I think)
GSkill DDR2-1066 (2x2GB)
Powercolour HD4850
Corsair HX620w modular PSU
2x WD Black 640GB
1x Crucial M4 128GB

I leave all fans on low speeds and have replaced the stock antec ones with some super quiet Noctua's or something, HS has a fan on it.

OC settings (from memory, but I can post CPU-Z and BIOS snaps when I get home)
Multiplier: 9
FSB: 445
PCIe: 105 (I don't know what this does)
FSB strap: 333 (I don't know this one either)
DDR2: 1086 (I think)
DRAM: 5-5-5-15 (I know lower = faster, but that's all I know)
CPUv: 1.375v
CPU PLL: 1.6v (again, no idea how or why to choose a setting)
FSB termination: 1.28v (another one)
vDRAM: 2.20v
NB: 1.26

I remember somewhat how to decide what the FSB is meant to be, and how it relates to ram/multiplier and why lower vcore is better unless it impacts stability. Using a program I found called "CoreTemp" I saw that I was averaging 30-35c on both cores at idle, 45-50c after 5-6 hours of non stop video encoding that I was doing last night. What else can I do to test my system for stability? Memtest and I remember their being some CPU stress testing program. Thanks for reading!

please return this value to defaul (100) or at max 101. This can fry your hdd if go too high.

Yikes! Alright, putting that back to 100 the moment I get home. If you dont mind explaining what does that setting do exactly? The little walkthrough I followed mentioned nothing about it being dangerous

the pcie is the controler for the pcie slots on the mother board it isnt recomended to change the settings on it unless you want to have your graphics card soudcard and anything else thats atached to your motherboard bursting into flames

you can overclock it slightly but i dont think thieres any improvment in performance just a lot more heat plus the chance off something expensive bursting into flames

I don't recall the pll being that high for an e8400. I recall that kind of pll for quads back then. I recall 1.5v max...

I should have come here first! I'll revert everything as soon as I get home, do you think I'll lose stability with my overclock by putting those select things back to default?

you shouldnt lose stabillity if anything stabillity will be improved

Well, I'm back from vacation! I somehow convinced myself to do what I didn't need to do and I picked up an XFX HD 7870 with twin fans and installed it yesterday. I also took the time to clean out my computer for the first time in over a year and my god the dust that came out! Organized all my cables and removed some unnecessary hard drives to put the remaining two and the single SSD way down in the bottom cage. Much much happier with it now. With the 4ghz overclock, SSD, and new videocard the computer seems to be running significantly faster than before and temps went down after the cleaning and organizing. I also did a test run in the original crysis last night to see how much performance has changed as I don't have any newer games since this one.

Old settings were 1680x1050 with everything on medium or low and 0xAA (had to use second screen to play)
new settings are 1920x1200 with everything on very high (except for physics) with 4xAA and am finally able to use the primary monitor. I must admit, I'm a touch disappointed by the graphics in this game at the high settings, I guess I expected more from the maximum settings. The biggest issue is the way things pop into high res at a relatively small distance but regardless, I'm satisfied with the performance. Maybe I'll look at overclocking the card a bit?

EDIT: I lied! XFX HD 7870, not MSI. Editited post.
