post #53631 of 67884
I actually have about 5 or 10 little blower fans i bought ages ago for something. Was thinking of using those for something but i dont remember off hand if they are 5v or 12v so i need to check. They are small enough to squeeze into the space behind the radiator/cpu fans.

Also if i switch the top fans from pushing out to pulling in then theres some airflow on the other end of the VRM and that rear area right there but i think flipping those fans might mess with the airflow through the case and through the rad... Might just have to try it and see. I have other fans laying around.. I could shoehorn in a 90cfm 140mm xigmatec fan in place of that little one but the little one shifts an absurd amount of air for the size of it and its firing it all out into the northbridge and over the VRM sinks.

Rome wasnt built in a day though.. This is my first setup fan wise. If i really need to i can make up brackets and stick a few small/powerful fans in that area.

This was also a "budget" build as much as was possible. The xigmatec 140mm fans i got used as they were removed from cpu coolers and was an auction for 3 of them. Building up a rig for the gf also so im coming down with stock corsair case fans and cpu cooler fans at the minute lol

No the rear of the motherboard where the socket is.

fan blowing onto rear of mobo to cool socket and rear of vrms


small fan fitted at rear of mobo

This will help you with your socket temp, it's one of the first things we recommend here.

just dropped to 4.7ghz and lowered vcore 1 step (can possibly lower it more though, was just a tester for temps). managed 2 passes on IBT AVX on high before i manually stopped the test when tmpin2 eventually hit 81c. i cleared temp max/min before starting the test after letting all temps stabilise at idle for a few mins. the min temps you see are my idle temps here at 4.7ghz, much the same for 4.8 and 4.9 at idle. not sure if its because i ran the max test at 4.8ghz and ran high at 4.7 here but it seems like temps were slower to rise. tmpin1 actually held in the mid 60's but coming towards the end of the 2nd pass started creeping up and i pulled the plug at 81c.

is there any other indication of it being stable that doesnt require sustained full load that causes temps to rise as much? gta doesnt pull as hard on the system so while i may not be able to run 4.7 or 4.8ghz for extended periods of time in IBT AVX i can sufficiently regulate temps for gaming in gta v.

im not looking for 24/7 bragging rights just a real world OC that i can regulate sufficiently for gaming. these runs in IBT AVX are with all fans at 100%, i was running gta at 4.9ghz with all fans on smart mode.. 75% on cpu fans up to 40c (100% by 45c), front and top case fans at 80% up to 40c (100% by 45c) and the little screamer on VRM/northbridge sinks at 75-80% (100% by 45c) and i heard the CPU fans speed up once for a few seconds and the little fan sped up about 3 times for a few seconds so its able to regulate in gta just fine,

.

I'm kinda done with it. You keep saying the same things over and over.

If you decide to give it a shot in the proper way, start lower work your way up in steps. And then get across some problems and actually have questions about the process I am glad to help. No problem.
But I don't want to keep saying how I (and most of us here) advice you to approach your overclock.

Lastly, no. I don't think there is another way to clarify stability without actually stressing the system. That's the whole point of stability testing after all. biggrin.gif
But you can just run it on 4.9 and game if you want. You will get into problems in the long run though. But go ahead. smile.gif

About the fan behind the socket. I mean actually behind the socket. Like in, screwed down to the right side panel having it blow air on the backside of the motherboard and socket. Exactly against the back of the Corsair cpu block.

About the small fans. Sure, go ahead. More is usually better, especially with the hot-heads Vishera's.

Fan orientation. My actual thought when seeing your fan setup for the first time was to change the orientation of at least one top fan. I prefer positive pressure so I'd change both fans to intake. But if you only change the rear fan around so it blows in fresh air, the vrm gets some flow and your radiator also gets fresh air. Alternatively you can change the radiator itself around, what is actually recommended by corsair anyway. Making the radiator pull in fresh air and the two top fans pull it out of the case.

Thats what im saying though... Vrm and nb get lots of air as is and with the top fans pulling then its sucking the heat and air from the small 3000+rpm 0.7a fan out the top.

Plot thickens on this mystery tmpin1 high temp reading... https://forum-en.msi.com/index.php?topic=254668.0

I just ran 1 pass on ibt avx with case side open and could feel no heat on nb or vrm sinks. Supposedly msi say its a dummy reading in that link above?

It could be your chip, but I would say it's a mix of your chip, not so great mobo and lacking cooler.

The recommended temps are to keep CPU Cores around 60C ish and Socket at 70C ish but I think the new numbers are be 70C for the Cores and 80C for Socket. Any one who started OCing a while back though try not to get near 70C period though on Visheras.

The lesser quality 6 Phase design of your MSI can hold back your OC compared to a lot of the users with a kitty (sabertooth) or ROG mobo with some of the best Mosfet/vrm at 8 phases.

From my experience if you can't pass IBT VH 20 runs you have a high chance of freezing or crashing in some games. Even 20 runs might not be enough for final stabilization tests. I agree though do not go above 1.56v especially with your current cooling. Only options are to have a inefficient mid/high OC with high voltage or a efficient mid/low OC with a lower voltage setting.

As for the comment about everything is unstable if not running at standard speeds. You sound like hurricane. You are right, but if you test your OC ridiculously and your PC never crashes then you can live your life without worrying about instability until something appears to crash your PC. You do mediocre testing then there's a higher chance your PC will crash on you during an important thing. More to worry about if tens of people tell you your not stable.

Haf 922 with 5 Coolermaster 200mm fans fitted!
There's fans on the VRMs, fan on the northbridge, on the southbridge, on the rear of the socket, plus many more to guide the airflow thru my case, the joke is I need to file a flight plan with my local airport when I start the ugly beast!

I was waiting for these pics haha

if the reading doesn't change then yes it isnt really a sensor...vrm fan should blow down on the vrms not pull from it...the socket fan I'd on the back of the motherboard not the front that blows on the rear of the socket and I'd offset so it news on both the socket and back of the vrms...I'm just trying to figure out why you are refusing to run a proper stress test...according to your screen shot you didn't overheat with the few runs you ran on high...if you are freezing on any of the ibt runs you either need better cooling, more voltage, or more cpu nb voltage...or a combination of any of these...cooking would be my guess with those volts it won't be tamed by an h55 with any fan configuration...

The motherboard you have will probably not get past 4.6 ghz on IBT AVX , even with a very good supporting cast of quality psu and cooling. That said you can usually game etc at higher clocks than you can stress with these chips because not many games will fully load 8 cores, at least not for very long ( mostly just during load screens etc.).
Others have given some good advice, but it's up to you to follow it or not. Unless you have a spare motherboard, I'd keep clocks at 4.6 and the voltage below 1.5
Just a bit of information for you to consider, the difference in wattage between the stock VID and the 1.55 volts you are trying to push is at least 150 .

This is not IBT AVX verson, sorry I'm not just picking on you but just wanted to point this out.
You'll find the AVX version here http://www.overclock.net/attachments/13202

When I set it to run a few passes on High (with a butt load of things running even) it looks like this

note the huge difference in GFlops and Time.

tmpin1 is socket. No doubt.
When you see the screenshot you posted, that temp reading raises from 40 ish to 80 ish. And 40 idle seems like a temp you can expect in your situation with your clock.
So, sorry to say but it isn't a mystery high temp reading. It's just you going crazy on the not so great board and cooling. biggrin.gif

Agreed, agreed and agreed.

I have a kitty so i can talk my share. Previous 990fx ud3 also had 8 phases but was nowhere near as stable as this little kicker.

Others have given some good advice, but it's up to you to follow it or not. Unless you have a spare motherboard, I'd keep clocks at 4.6 and the voltage below 1.5
Just a bit of information for you to consider, the difference in wattage between the stock VID and the 1.55 volts you are trying to push is at least 150 .

Yep.
Like I said a few pages back. "If he wants to go on with what he is doing and damage things prematurely, feel free".

Crazy, right? The amounts of heat these chips put out. One could easily cook on it. tongue.gif

You'll find the AVX version here http://www.overclock.net/attachments/13202

When I set it to run a few passes on High (with a butt load of things running even) it looks like this

note the huge difference in GFlops and Time.

Oops. That slipped by me.

Thanks Sandman, how are you btw?

Doing GREAT, well till win10 came my way.
Having to slightly re-tune the OC due to this. (not that it's a bad thing) biggrin.gif

Thought I'd better point that fact out about the non AVX as we all know how the true AVX adds even more stress/temps etc than standard version.
If he thought he was having issues with heat before...
