Need help OCing E4500

post #1 of 43
Thread Starter 
hey guys, heres my rig:

Intel E4500 @ 2.2GHz (stock) w/ a Tuniq Tower cooling it (idles at 17c, load at 29c)

MSI P7N Platinum

2x MSI 9600gt's

2x1GB Corsair DDR2 800 Ballistix

Corsair 620HX 620w psu

My issue is this: i can't get my processor to overclock correctly without being incredibly unstable. Is there someone with experience with my board that could help me out? Tried running at 3.0GHz @ 1.35V and got no luck with that, juiced the northbridge southbridge, ram, everything to see if it was them. i have spread spectrum turned off. i even set the ram timings to auto so that it could set them to whatever so that it would be stable. as it is, my E4500 is bottlenecking my 9600GT's and that's not something i want to have happen. if i can't get the E4500 to perform well enough for my 9600GT's, should i snag a Q6600 or E8400? I know theres batch issues with the E8400.

anyway, thanks for the help.

800MHz is a pretty healthy step up for any CPU so I wouldn't doubt if it takes some more vcore to get to 3G. Did you jump straight to 3G or did you work your way up with FSB and volts? My e2180 takes about 1.4v to get to 3g. You CPU should be able to get a decent overclock so hold off on that CPU upgrade for now.

yeah i went by 25mhz increments, and it booted stable fine, but got a BSOD the instant prime95 started. as for the voltages, i have no idea what to set that to. i just sort of picked a decent number that kept my cpu under 1.55vcore
any help with that?

lol, you'll need to go to 1.4v to make your CPU stable, theres alot more then just blind guessing to overclock your system. Have you lowered the ratio for your RAM speed yet? It must be running at 950mhz by now if not.

Can you please download CoreTemp and post the VID number of your CPU? Once I get that I can help you more.

I will help you get where you want to be..... 1st of all, what is your goal for an overclock?

You can start by viewing and learning the bios in your manual here http://global.msi.com.tw/index.php?f...36&type=manual

So here's your little orientation to overclocking on your board....






My advice to you is to start out small...

CPU FSB - 333x9 (3GHz Effective)
CPU VCore - Try 1.4 V if you cannot post or boot windows increase to a maximum of 1.5
FSB Voltage - Leave Stock for now
MCH (NB) - Leave stock for now
RAM - Set to 333 with a Multi of 2 that will put your DDR2800 running at 667, therefore you should have some headroom to tighten timings.
RAM Volts - Whatver is needed for stability, you can increase this as needed.


The over all goal for you should be 400*9 = 3.6 GHz with your ram set at 400*2 = 800 (Stock Ram Speed) which will give you a 1:1 ratio and the ability to tighten timings as well.

One little question, what's your stock load CPU voltage?
1.25, you should be overclocking very easily.
1.35, you didn't get the best chip of the crop, it meets the standard specification of the e4500 (2.2ghz) and it takes more voltage do the work of a same e4500 @ 1.25v, results will be different from chip to chip, if it takes 1.5 to overclock to a mere 3ghz, you just were unlucky and didn't get a nice chip.

But most likely, you just didn't lower your ram speed. Set it a notch slower and loose the timings a little if needed and you should be able to overclock past 3ghz.

I got a E4500 that has a VID of 1.2000v and I can get it to 3.2GHz at 1.3000v Orthos stable.

Just need to replace the stock cooler.

I had a E4300 with a VID of 1.3250v and it would take 1.4500v to get it stable at 3GHz.
Super Over 9000!

thanks for the responses and dealing with me as a noob, heres my coretemp and cpu-z screens.




read the manual a few times now, got myself pretty well oriented with the BIOS. the only thing is I have no idea how to change the ram multiplier, or, is it just at 2 because its ddr2 memory (thats what ive heard at least)

what i did when i attempted to OC was just eventually got to 3.0GHz [left the cpu multiplier @ 11, jumped fsb to 1138 (thats what it says in my bios, its definitely not 1138, i just dont know how to get it down to the normal readings) and upped the voltage to 1.35. left the ram at 800.]

will post later with results
