My E8600....is there room to go higher??

post #1 of 13
Thread Starter 
I am running an E8600 3.33 OC'd to 4.125 STABLE on an ASUS P5n-E SLI board max'd out ram @ 8gb + nForce 650i SLI Video.

I am running H80 Water Cooling.

20% Load 52-54C

100% Load 59-63C

VID 1.25

Think there is any room to go higher?? If so, where should I begin??

Thanks,

James

it's been a long time since i've had my old e8400, but i do not remember voltage that high.... It seems really high.

That voltage is killer lol.

How are you getting 1.25 volts?

I think his VID is 1.25,not to be confused with his current vcore. CPUID is showing over 1.5v So unless its bugged hes using over 1.52v or even more if he has vdroop.

Yeah, don't go over 1.45v on the vCore. It could be auto voltage kicking in?

All that you should have to do is raise the FSB to what the RAM is rated at, add some vCore voltage and go from there.

Seeing as you're running 8GB you're less likely to get a higher OC.

You may want to give the IMC/Northbridge a small voltage bump, I remember my E8500 did 4.1GHz with;

1.33v or so
1.52v on the RAM (I had 6GB DDR2 800) - I ran the timings overclocked to 5-5-5-15 from 5-5-5-18 too
A bump on the North-bridge (It had some weird name on my Ep45-UD3P)

It's been a long time, I can't really help you out more unfortunately. You could also try loosening your RAM or getting some better RAM but at this point unless you can get it for really cheap or free it's probably not worth it. (1100MHz RAM is hard to find/expensive usually)

Your temps are fine too, up to 70c is okay but you shouldn't be getting there though. Especially if you're at 1.52v right now when you use less it should be a lot cooler. I remember my E8500 topped out at 42c with a Hyper 212+, it had the bugged sensor at 41c and only worked from there upwards. The stock cooler would do 73c at stock for reference (1.25v)

Thank all of you for your input. I haven't tinkered with my settings since 2010 and have had it at the settings you see running since then. From what I remember, when I gave less voltage it would not stay stable. I will play with this with the suggestions that you have recommended I start with. I do remember getting 4.8ghz but was not stable and really was just too frustrated to try to find out why. re: Memory I currently am using Micron technology PC2-6400 (400mhz).....there is a faster memory that is compatible with my motherboard??

Personally I woudnt get more upgrades for lga775 and less for a 1.5v e8xxx because the limit is around 4ghz and newer cpus are faster than 4ghz e8xxx..maybe getting a xeon lga771 and do the lga771 mod if you dont want to spend more money on a new cpu quad core

Yes bring the Vcore down, its way to high for your OC. For reference, my E8500 was prime stable at 4.03 w/ 1.21v set in bios.
