Overclocking with the BCLK on a "non K" Cpu and a non overclocking board

post #1 of 6
Thread Starter 
Hey Guys

Hope this is the right area to post this thread so here goes...

I would like to ask your opinion on something which a friend and I have debated on for several weeks now, and I'd like to see whether I have some valid points here.

So firstly i'd like to confirm what my PC's specs are:

Gigabyte B75 D3H
Core i5 3550 (3.3GHz OC to 3.9GHz Turbo) Coolermaster Hyper TX3 EVO Dual 80mm Fans
16GB Patriot Viper DDR3 1866MHz running @ 1678MHz 7-7-7-20 (Lowered the timings to compensate for the lower clock)
Asus GTX 480 (Stock)
OCZ Vertex 4 SSD
Coolermaster EX2 625W

etc,etc (as per my sig)

Okay - so I've read many many MANY a thread about how dangerous overclocking with the BCLK is.

but just could I wanted to I decided to give it a try with a very small increase, since some say 101MHz is fine, 103MHz is fine, and some even say 105MHz us fine.

so I upped my BCLK from 100Mhz to eventually landing on a BCLK of 104.7MHz to give me roughly a 3.9MHz Turbo Clock.

I have been running with my BCLK on 104.7MHz for roughly 3-4 months now, and haven't had 1 single data error nor, blue screen, freeze nor crash.

Well I will give you my point of view on the matter and your comments would be greatly appreciated in any way.

1. Why is overclocking with the BCLK considered to be so unsafe? (Yes all the components are tied to the BCLK) however I have "somewhat" compensated with the Overclock by means of:
-Buying higher rated memory
-Left My GTX 480 at Stock, since its automatically overclocked it by virtue of the BCLK (I normally overclock all my VGA cards)
I run a SSD (Nothing to compensate for the higher BCLK here)
CPU has a decent cooler
Ambient temperature is good
Not pushed the BCLK very far

So if I've done the necessary why are people so dead against it?

2. The life of the CPU is shortened yes, but by how much shorter? Will it even be relevant before I upgrade anyway? (If the life is for eg. 10years to 8years, should I even be concerned?

3 Then I made this statement, overclocking shortens the life of the CPU, however in my very humble opinion, overclockers generally have superior hardware compared to those with stock systems, better CPU coolers, better cases, better case cooling, better monitoring, better knowledge or what signs to look out form etc, etc. Since they know what they're doing (generally) they would necessarily inflict the level of hardware damage that someone would, for example that has, a poor case, crappy CPU cooler, huge dust collection, etc, etc

So if I was to look at a time time, Person A who is someone with an Crappy cooler, poorly mounted, poor paste application (or old paste, or even NO PASTE) no case fans, and high ambient temperature, and no free airflow. (to me this is CPU torture)

Compared to person B (like myself) Overclocked CPU, regular cleaning, Good CPU cooler, case air flow, sufficient and done the correct way, etc, could even have longer CPU run time than a person running a CPU at stock?

right now I am going to continue running my CPU overclocked using a "non K" CPU on a "non overclocker" board i.e. B75 Board

I have benchmarked, ran various apps, gamed (last game was battlefield 4) everything under the sun without a single error whatsoever

I can only comment on my first hand experience, and thus far everything seems peachy.

oh yes, i do consider myself to be relatively experienced, so no, i'm not doing this blindfolded, lol!
I overclock using the BIOS, don't do the whole software overclock thing...

Yours comments please?

Thanks!thumb.gif

1) Overclocking with the BLCK isn't considered unsafe, it's just known on Sandy and Ivy Bridge to cause instability. Meaning, most people try to play with the BLCK and can't even get 100.50 out of it let alone 103 or 104.

2) You aren't overclocking your CPU by much, that chip turbos to 3.7 you pushed it to 3.9 that's hardly an overclock at all. Not trying to burst your success but realistically, that's only a 200MHz increase.

3) The days of people losing their CPU life span by a large margin from overclocking are mostly gone. Aside from overvolting your chip by a large amount (over 1.45v VCORE). Most people with 1.45v VCORE and under see regular life span with their CPU. Meaning, not too much degradation. Since the average overclock is 4.5GHz most people are under 1.45v, way under and because of that their life span is basically unaffected. As in they will upgrade their CPU and Motherboard long before the CPU will die on them. Basically though, with your understanding it is in most ways correct. People who are computer enthusiasts will take care of their computer better than someone who is not, so they will probably get a longer life out of their components anyway.

By the way, that chip can do at least 4.0GHz or so with the BLCK + Multiplier combinations. All you have to do is go into the BIOS change, set active processors to all and raise the CPU Ratio to 40 if you can try 41 too. You will probably have to raise the VCORE voltage a bit or raise the offset a bit to hit 4.1 or 4.2 (not much more voltage though) which I believe is close to the the max that have people achieved (around 4.2GHz). Not sure how limited you are on your motherboard with what settings you can change but that chip can do at least 4.1 or 4.2 on or close to stock voltage.

Thanks for the quick reply BiG StroOnZ

I actually just wanted to test the theory regarding the BCLK and the apparent damage it causes, used my PC as normal, gaming, using apps, and everything else just to see if any type of error would surface.

Yes its a marginal increase, starting at a BCLK of only 101MHz I slowly worked my way to 105 (Which shows 104.7 in CPU-Z) I will take it further, but I prefer doing it in very small increments and thoroughly testing it as apposed to just having it boot, bench and claim that it works.

So currently im on 105MHz, looking to get it somewhere to 107-110MHz if I am allowed, obviously closely monitoring it for any kind of foreign behaviour.

I don't want to push the BCLK too much, since the GTX 480 will be the limiter, since its already a "hot head" at stock, i'll need to keep a close eye on temps, but so far it hardly touches 80degrees on full Load which is encouraging.

Thanks for the tips, much appreciated!

man i too have the gab75-d3h but i have it with a i5 3470.
how do you change the bclk on this mother board?
and if still possible change the bclk on this mother board, what bclk i should put?

aditional info:i have Cooler master Hyper 212 Evo. and 2x4gb 1333mhz. and sapphire hd 7770 with overclock (by me) pciexpress will auto overclock with the bclk change right? i should underclock the GPU.

There will be point where PCH Voltage and PCI-E Voltage will need to be lifted as well as DRAM Voltage. There will also be a point when it doesn't matter how much voltage you run it won't be stable. Most I have ever run 107 BCLK on my current board with a Xeon E3-1271 v3.
