4790k idling at 60c and CPU throttling in AIDA when XMP set (2400c11)

Thanks again.

The more I think about it, the more I feel like I haven't actually damaged anything but until I get home I'll still have nagging doubts.

I guess I could have warped the board, socket or the bracket but I only tightened by the tiniest of amounts...no idea how checking the h60 was seated properly then tightening a whisker could get me to such a bad situation.

Also, in bios last night I noticed that at 1.218v I was idling at 50c+ @4400mhz.

On the stock cooler with a poor paste application does that seem alarming to you? This was without the XMP loaded.

Cheers.

you have to be pretty heavy handed to cause damage.

i take it you used a screwdriver to tighten up ?, if you did then unless you push down with a bit of force and/or REALLY tighten the thing to the motherboard to damage it.

what does the chip read at stock settings, in bios and on something like cpu-z ?

thing is with the stock coolers most arn't meant for overclocking, and mmj mentioned that the chips seem to run a touch hot even on stock volts, so see what the stock vcore is and it will give you an idea of how much your adding when your on 1.218.
 
Thanks.

No I'm ultra careful and only went about 1mm past hand tight the first time then maybe the same again the next time with a gentle push to check for give. However it went pear shaped from there and I was throttling in bios after a minute or two. I understand that I probably badly unseated the block when I checked for a good join but I really didn't think things would go that wrong.

It's really hard to get a clear picture in my head of where I'm at with it at the moment as I didn't have to test it all properly last night. I just got it to a reasonable temp with the stock cooler so I could sleep.

All I can say for sure is that idling at 800mhz it's 1.14 ish and about 29c but in bios it ramps to 50c+ At 4400mhz and 1.218 volts on the stock cooler.

Wish I'd run a game or something like that just to check I haven't caused a bad join.
 
if the default clock/vcore sits at 29 ish then i don't think you've got a major problem with the cooler.

admittedly load temps matter more, but if the default clock/vcore was idling at 40-50 then i'd be more concerned, just looks like the vcore your adding to get the overclock is the main problem.

can you overclock it at all on default vcore ?
 
I think it could be good to clarify my situation here.

The only overclock I have ever had on was the RAM XMP.

When I turned off the XMP my temps were about 77-81 in AIDA with FPU.

At this point I tried to make sure my cooler was properly seated and that's when things went wrong.

As my case doesn't have access to te underside of the mobo I had to disassemble the pc and because I just wanted to make sure my chip and mobo were ok I quickly slapped the intel cooler on.

My current idle of 29c in windows and 50+ In bios are on the intel cooler at optimised defaults setting in BIOS.
 
well the 77-81 temps arn't really an issue, there at the top end of safe but it depends if it was after 30 seconds or a few minutes.

what are you using to read the temps in windows ?

had you noticed the temp in bios before the issues ?


also, what bios is the board running.

Thanks.

Top end of safe? Well for the past month the XMP overclock has had me in the mid 80s touching 90 in lightroom exports.

Here's me thinking 77 was ok! It was after a few minutes by the way.

I use hwmonitor, can't remember previous bios temps and I'm on latest f4
 
had a look around and seen a fair few mentions of high in bios "idle" temps.

any idea what the room temp ?

if the vcore is set to "auto" , set in manually to the default shown in bios.

noticed the case listed in your spec, what sort of air flow have you got setup on it, maybe try taking the case sides off just to make sure thats not an issue.

what make of memory are you using ?

edit:

just had a thought back to the H60, did you have it set up for max rpm on the fans ?

Room temp was about 20 last night.

I'll try setting voltage manually to 1.218.

When testing the h60 with the XMP on I had the case closed but last night when I tried again it was open. These were my best temps by miles. Fan is an SP120 high performance and it was definitely at full speed. Incredibly loud and lots of air flow.

Previously I was running the stock case fan and cooler with the XMP overclock but I was also blocking the case with the cages. From now on my drives are going on the floor of the case. I understand why my previous temps were so high now...before last night's brief success and euraka that the XMP was causing the high temps.

Memory is Kingston hyper beast 2400c11 at 1.65v.
 
Things aren't looking great.

BIOS reset and temps are 75 ish in gaming with the stock cooler and touching 92 in lightroom export.

Soon up to 100c with the H60.

I'm starting to think something is seriously wrong now.
 
ok I've gone back to the stock cooler and now things are a lot worse.

Bios takes my CPU towards 100c pretty much straight away. Of course I now have minimal paste but I turned off the instant I was in BIOS.

Surely thermal aste cannot account for this?

I've read you can run without paste.

I think i must have warped my board, any takers?

If I slap a layer of paste on tomorrow and my temps seem semi normal I'm just going to be glad I didn't totally mess this rig up.

if its higher with the h60, either theres a problem with the unit or its not seating properly.

i'd leave it alone until you have some thermal paste, then clean the processor & both coolers.

also, check the motherboard around where the cooler sits etc make sure you can't see any obvious damage.

did the board come with f4 already loaded ?, might be worth reflashing the bios

Yes it feels solid and connected with the h60 on.

Last night all I did was try to gently move the block and tightened slightly but maybe that has done it.

The board seems fine to me and appears to make a straight line across the heatspreader and the heatspreader itself seems fine.

Underneath the board at the socket it could look slightly bowed but I honestly can't see how that would have been caused.

If the board is bent and requires a thick coating of paste to work, what am I looking at temps wise do you think? Is it going to be liveable with?

Also I've inspected my cpu and mobo pins and they are absolutely fine.

Thanks for your help.
 
having a look around there seem to be a few mentions of high temps on these processors, so doesn't seem to be just you.

if the board is warped i don't think extra paste will make any difference tbh, and extra paste will cause higher temps than some properly applied.

might be worth trying to undervolt the processor a touch if you can.

also, go into bios and turn hyper threading off see if that helps drop the temp, i know its not ideal full time, just want to check if it affects the temps.
 
Ok well I'll have to hunt down some paste tomorrow.

If that doesn't get me up and running again then I'll have to think about getting a new board one wa or the other...or maybe finding some way to prop it up from underneath.
 
Quick update as waterfox decided to lose my post...

Socket appears to be slightly bowed underneath, exactly as you would expect it to look had the CPU installation stressed it...it's in the same direction of force. I do not believe it is possible to do that by over-tightening the H60.

The board appears absolutely straight.

When I took the heatsink off the stock cooler and lay it on the CPU there is no give whatsoever, it feels perfectly flat and secure. Obviously I realise that if the board is warped and pulling the cooler to one side then that will cause these terrible temps.

I'm going to try the stock heatsink tomorrow placed flat on the heatspreader and weighted down and hold a good fan above it. I firmly believe that if temps are fine this way but not with the cooler installed that I have a warped board.

If thermal paste sorts all this out I will be surprised but I've not given up all hope yet.

Thanks again for your advice.
 
Another update! Success at last of a sort.

Stripped it all again and remounted the stock cooler.

Idling at 29c again and ARMA 3 took it to 63c.

Hopefully it can take the XMP again now.

Just need to get this H60 working now,
 
Yeah I did finger tight last night with no success.

Part of me is tempted to leave it but I can play arma 3 on low on the hd4600 when the ram's overclocked so I'd like it sorted for tonight as I'm not getting my gpu until next week.

I'm going to hold down the h60 by hand next time to see what sort of temps that gives me then compare to when it's screwed down.

if you work the h60 the same as you have the stock cooler and it still doesn't perform then it could well be a problem with the h60.
