E8500 Overclocking

[xp0zed]

Hey everyone, Im new around here really impressed with the expertize around ehre.

Well i've been googling for a while now on the best settings to oc an E8500, First time Overclocking a CPU just wondering if you guys can give me some tips/advice on what settings to put in place in BIOS..

Here's my specs:
-CPU E8500 (Thermalright Ultra 120 Extreme Heatsink 2x120mm Fan)
-MB Asus P5QC P45 1600 FSB
-RAM 2 x 1GB Corsair DDR2 PC-8500 1066MHZ
-PSU Apevia 900 Watt
-GPU ATi * Sapphire HD4870 512M/GDDR5

Much Appreciated.

How far do you want to go with your processor? I just noticed you only have a 4pin cpu power connector, that may limit things a little.

Hello and welcome to the best tech forum on Earth. I recommend a First Timer like yourself to read this
http://forums.techpowerup.com/showthread.php?t=22916 .

Also read the other stickies and then ask if you have any problems or do not understand.

Im aiming to take it to 3.8GHz or 4 if possible, the thing is im connecting my cpu fans directly to the 4pins coming out of the PSU etc. Also thanks for the information SK-1,
I've read through it seems interesting, just need a few example figures to know where to start from, like typical settings for an e8500 overclock than i can probably work from there.

Definitely start with the stickys. Everyone has to start there first. Then after you have read it, we can help. I am currently using a E8500 running for 4ghz on only 1.29 volts.

I will do what I can to help you get there if it is possible.

4 will be a piece of cake, EO or CO stepping. With my e8500, I just kept it all stock voltage wise and start bumping up that FSB. Run some stress, then bump up some more till you need a volt boost. You can run your CPU safe up to 1.45v. I once even found, in Intel's own site, a page that said 1.46 was safe.

Still read our info in the stickys.

Yep as suggested, start with the stickies/articles/guides. Best thing you can do is take your time and read, research and learn about the components you have. Use Google, it's an excellent tool, search your motherboard, processor, power supply, etc...learn about them, see what others are using for bios settings, cooling, getting for temps, etc.

Guides will give you a general idea, when I typed the Overclocking is Easy originally that's all it was, to educate users that they can get the info they need by not just asking for help but by also helping themselves learn, which is extremely important. We can tell you settings, but you won't necessarily learn from that...you will then not be able to improve or optmize your overclock, maybe the suggested settings are unstable, we stay increase the CPU voltage to 1.45v or something, you do...it's stable, but could be stable on less voltage, your temps are very high and the chip is very stressed, that is a bad situation. So learning and researching are where you should be at right now, not the actual process of overclocking.

Find motherboard reviews that have screenshots of the bios screens, get into your MB's bios and get familiar with it. Find the settings that the screenshots provide within your bios, read the owners manual, learn where the Clear CMOS jumper is at and how to use it. Things like that are very important.

It's good to start by asking questions for sure man, my answer to you is now to read and research, sure we could probably get you overclocked by posting settings and voltages, but if you don't understand what you're changing and why, it'll do you no good in the future if something should happen or you change systems or try to help someone else, plus you'll be more confident when you do your first OC step and it boots into windows without issues because you took the time to take the correct steps to being properly prepared.

hehe sounds good man, so im gonna start off by bumping up fsb by 40 mhz a time, if i dont get a boot ill just reset cmos and up a notch in volts ill keep you guys informed thanks.. keep them ideas coming btw whas E0/C0 stepping?

 

[xp0zed]

ok atm i'v just changed the FSB from 333 to 390 and clock to 9.5, Core Idle Temp: 31c Load Temp: 40-45c Using core temp monitor and hmonitor. i was wondering how to use Super PI? It says select digits of PI to be calculated. Also any other stress test programs, seems some of the links on the thread 'must have programs for overclockers" are broken. I think i could clock it to 4ghz.. it doesnt even feel like its stressed just played 1 hour of Counter strike source. Temp didnt go over 45c

Hehe pushed it up to 4Ghz.. using 420 x 9.5

Also i've noticed something with my multiplier it keeps flicking between 6.0 and 9.5 in CPU-Z and Another CPU Monitor program, Any idea why?

 

[Pum]

The multiplier thing is an energy saving feature (forgotten it's name.) When the system is doing little it drops the multiplier back to x6 to save power, which should also reduce heat and electricity consumption - this is good. When you put load on the system it wacks the multiplier up.

I think most people disable this and similar features in the BIOS when working on OCing, and when they have their OC stable you can try enabling these nice but not OCing features.

BTW, which CPU cooler are you using?

Im using a thermalright ultra 120 heatsink with 3 120mm fans around the casing.. so it gets alot of air.. my load temp max is 46-47c havnt been over.. but i just had a crash i think, i went out and came back after 2-3 hours the pc was restarted.. wonder if i need to raise vcore to 1.3 sitting at 1.25 atm..

EDIT* also im new to this sorry if i sound noob but when people say raise vcore to add more power to cpu is that the CPU voltage? FSB voltage NB Voltage or what? because its confusing..

As previously recommended, I'd suggest reading the guides here and elsewhere - Google overclock* and you mobo or chipset. I found this guide very enlightening: http://forums.tweaktown.com/f69/gig...erclocking-general-bios-tweaking-guide-26112/ It is primarily aimed at Gigabyte mobos, but plenty of useful stuff in there for everyone.

What are you using to measure those temps? Is that core temp or what the BIOS reports as CPU temp?

Did you notice that according to CPU-Z and Coretemp, you only have one core?

 

[xp0zed]

One core? lol how does that work out? Also my pc was only stable for 2 hours on 4Ghz, i went out and came home it rebooted. I raised vcore it wouldnt boot up at all. any ideas?

Also when i turn SpeedTrap off it still uses energy saving so changes my multiplier back to 6.0 i have no idea how to disable it done some google research. Also googling how to oc doesnt help much because it all depends on what kind of board you use and mines a p5qc not everyone has good results with these boards.
