I think the main reason we haven't heard about it is mobo companies still want you to purchase their better boards. If the cheapest z87 board will work just fine, then why spend more unless you need a specific feature of that board. It just hurts their bottom line.

There are good reasons for purchasing a more expensive board, though. Such as specifuc features you need or better on board parts for enhanced durability.

I think this is due, in large part, to the introduction of FIVR, that is the moving of a lot of the voltage regulation logic from the mobo to the CPU and making it configurable. I think higher-end mobos still give you a lot (though arguably for much more than it's worth, that is you're paying a high premium), such as much more robust components, etc which would provide better durability especially as you push voltages higher. However, it's all hand-wavy...

To make sure if the mobo useless or not .. Probably need to run a gold batch on the cheapest x87 with a Standard overclock feature. If the cpu can go as high, darn it hurts. Speaking of overclockability.

Hey,



Thanks for the guide. I have a question regarding memory oc,
I have my 8GB(2 x 4 GB) memory rated at 1333mhz(Corsair CMV4GX3M1A1333C9) ,if i leave the DRAM settings to AUTO
It detects it as 1333 Mhz(1:5).
However i can manually set it to 1600Mhz(1:6), the system boots fine and infact i benchmarked IETU,and got a 100 point increase ,so i am sure it is at 1600mhz.I didnt change anyother thing in BIOS.

During bencmark i noticed that the processor TDP increased by 2W and temp by 1c

Is it safe to keep the memory at that frequency, i want to know before i stress test it biggrin.gif.

Thank for the reply Doug..... and i am doing fine other than being some what frustrated and confused lol..... yes Vring/Vcache on voltage...the only place i could see that voltage that auto has set for it was in the bios and in XTU...however i shall go and get HWMON now and find it....XTU shows Vring/Vcache voltage "0.800" nearly the same as bios shows it so i guess its was running just under a volt via the Auto settings....however i am sure it moves around under auto...as for gigabyte boards we don't have any kind of option to set our voltages and then take that figure we just set and take it from manual to adaptive.....

Adaptive On gigabyte boards is auto....so you are either in auto mode or manual mode....you can not set a voltage and then tell the gigabyte board to use adaptive on that figure..

You said ......"XTU says vring is 0.8v??? you set it to 1.1v? this is defo vring we're talking about? What is you're uncore multiplier set to?.....and yep as above it is Vring/Vcache ....i am talking about and yes i set it to 1.100 volts that's only a small increase ....do you think that's to high then as you seem worried about this setting?....also you asked what the Vring/Vcache multiplier set too ....it is on standard for gigabyte boards which is x35 and on a gigabyte board that means it turbo,s up to 40x.....4.00ghz in a stress test or when the CPU turbos up so my cache is set to x4O when the CPU is under load which is default....



Btw

So my settings are as follows now for 4.30ghz, do the look correct to you?

muti x43
cache x35 = x40 turbo
Vcore 1.225v
Vring/cache 1.100 v
Vrin 1.820V

Yes get it from intel website. $25 for 4670k and 4770k. Not much as far as the TOS.

I'm pretty sure it lasts as long as the warranty does. But as the TOS states, it can change any time they feel like it. I still haven't gotten mine tho lol

It's $25 man. Is that paranoia worth $25? Sounds like it should be lol. I'm probably going to get it, cuz my chip is pissing me off right now, I just may fry the thing...

FWIW, I have warrantied 2 4670K's that were overclocked/overvolted using the regular standard warranty that comes w/ it. I think perhaps they check for physical damage, but that's it.

thanks a lot, i searched their website and google and couldn't find it, the link is super useful!
i'm thinking maybe that's $25 well spent though i'm by no means extreme.... too bad it doesn't cover delidding haha, since i'm sure my temps would drop by a good 20C if i did it smile.gif

ha, so how did you explain the damage? "they just stopped working"? smile.gif
