Try to get to 4.1

post #1 of 8
Thread Starter 
Hi all,

Now that my system is running cool (42/43C on OCCT load) and steady at 4GHz, I need some advice to hit 4.1

I am stable at 4.0 with 1.46 vCore

At 4.1 (same NB, same RAM freq/lat, same HT that at 4.0), I get "error on core x".

The cpu doesn't hit the heat wall, I guess, as it doesn't even reach 44°C.

I've been told that if the vCore is too low, I should get a reboot, and not a core error... Is it right?

This a guess on my part but I believe too little vcore usually leads to a dropped worker in prime95. I dont use OCCT but considering it doesnt bsod in p95 with too little voltage, I assume it wouldnt in OCCT either...therefore my guess is too little vcore.

In my experience, bsod in stress tests is usually the memory or IMC (cpu-nb) clocked too high and unstable.

Since you didnt mention whether you increased vcore after setting to 4.1 I would say try 1.48-1.50v, you have enough headroom with your temps and you are on water...that voltage should be plenty safe.

Try it and let us know.

You should be ok up to 1.55 vcore with your loop.

Is your rad inside your case, or is your ambiant in the 18-22 range?

Incredibly off topic, but two questions BallaTheFeared...

1) Which Rasa kit do you have that allows you to hit 5.0ghz?
2) Your Memory is clocked 2150mhz right? Not 21500mhz?

Haha, yeah one more 0 never hurts.

Most SB chips can do 5GHz on the mid-high end air coolers, but to answer your question I have the RS240 kit with the gtx 470 added in.

I have my rad in the window like I did with my 1090T - I can fold at 5GHz with upper 30 lower 40C temps. But these chips also have cold bugs, it won't boot for me sub zero.

I'll let you know what happens when it warms up - but I'm thinking 4.6 will be a good spot in the summer for me (I'm not a fan of high temps with high voltage - but the chips seem to take it).

I think you should stay at 4.0
1. The extra 100Mhz likely won't make a difference
2. Your motherboard has no mosfet cooling, in which case I'd limit to 1.5V (though being 8+2 it's fairly capable). If you want to take full advantage, you will want to install mosfet heatsinks, because I have doubts on air getting near the mosfet area. Reliable mosfets/power phase are important for high TDP processors, and the heatsink can really help.

I got a great guide for this favorited at the ole' house, shoot me a pm and ill link it too you when i get off work skmanu.

As far as general oc'n tips, may suggest clocking your chip to stock everything, getting out some scratch paper and clock up one thing at a time to figure out where you mobo is at. Looking for post limits here. Once you know what how your nb/ht so on and so forth is going to behave, then its time to visit your memory and fsb... or vice versa... each item should be done seperately, and have easy access to your cmos clear dip switch... youll be using that a lot... this process may take a day or two and lots n' lots of reboots. At the end of it, you will know not only what your core can do, but what your mobo can do as well, also you will find out real quick were your heat walls and weaknesses are.
