Corsair H50 failed after 72 runs in linx

[Gaidin109]

What your QPI voltage. I found that it needs quite a high one to stay stable. Memory, not CPU. Prime used to do that to me after 5 hours until I upped the QPI to 1.335v and the IOH to 1.14v. Now it'll run all day long on 4.2Ghz.

I sometimes wonder at the voracity of Prime95 results anyway. It seems as if it's the software that could be a little unstable. You can run OCCT, LinX, IBT all day long and have no problems. But 15 mins of Prime Blend and it shutsdown.

I have it at 1.395v currently, I will try running Prime later today again with QPI raised another notch, I have IOH currently at 1.160v as well..

I was having strange lockup issues with LinX yesterday, it would lock up instantly with my stable 4GHz o/c profile, so I went and downloaded it again from XS and it started working fine again!!

Must have somehow corrupted the software or something, I don't know, but really strange nonetheless..

I have just done mine at 4.2Ghz, 1.312v at bios, 20passes LinX. Ambient room Temp is 24c Case temp is 26c. top temp was 80c, 77c seems to be the sweet spot.

I also agree the thread-title is very misleading, I first though the cooler had failed, but its Bulldogs OC that failed, He should try to be a little clearer. Confusion abounds I'm afraid.

You made me jealous now with youir excellent temperature and can you post me back with a photo what did you do step by step with your H50 installing and fans too ? Also show photo of where is your fans on both side arrow point to ?

Maybe I got a little wrong on my H50 and probably not seated correct ?

That amazing of 80C temp for your 4.2 ! What bios vcore did you use when u did disabled Load line calibration and did you use thin layer mx-2 or drop a small size in the centre on the cpu ?

 

[Gaidin109]

Vcore is set at 1.312v in bios. QPI is 1.335v. IOH is 1.14v. Dram is 1.66v. LLC is on for the 4.2 OC, I only disable it for my 4.0 OC as its not neccessary as the vcore is low enough without it.

Both Apache fans are running at 1300rpm, All fan control is disabled in bios. They are configured in push/pull exhausting out of the rear of the HAF932 case. (I'm not taking it all apart to do a step by step photo shoot, itwould take too much time and is pointless.)

I used a credit card to spread MX-2 on the H50 coldplate and then put a small spot in the centre of the CPU heatshield and then fitted the pump assembly. Make sure the screws are tightened slowly a couple of turns on each one in order until they wont turn any more.
Here is a PIcture....

Also there is a 230mm side panel intake fan when the door is on. Also the pump is now fitted with the corsair insignia upside down, so opposite to the picture (pic was take just before i changed it last week)

off topic I know, but that HAF932 looks like it would be a really great case for a custom WC loop, look at the space in the roof of that case, you could get a really nice thick 120.3 rad up there no problem.

I am now using MX3 TIM, got some with an order I received yesterday with watercooling parts, and I must say I am really impressed, it knocked 5c off my load temps compared to AS5!

I am still thinking about getting one of these H50 units for my Fiancees rig, as the results you are getting are really good Gaidin.

Many thanks Gaidin109 as I will removed H50 off and try turn screw tight as a time until it tight enough. I put MX-2 with a credit card spread out on the cpu but I didn't put extra small dot in the centre.

I think my 8 fans on Antec 1200 isnt good enough for my H50. Maybe I ought to get the same case as your. Can you open up your side case and take 1 quick photo of your pump (the one you say turn upside down)

Thanks again mate. As I know I had a cherry chip same as you.

 

[bulldog147]

Are the Antec 1200 top fan facing upward or blow inside by the case default ?

 

[zero-one]

They're exhaust afaik.

Sometimes its not the Hardware thats at fault. It can be extremely frustrating to spend hours trying to work out whats causing the failure just to find out your antivirus is interfering with Prime or something other crap like that.

I actually run my PC at 4Ghz 24/7. I only ever have it running at the 4.2Ghz for comparisons like this one. It just gets more and more difficult to OC for smaller and smaller gains. I think running a 2.66Ghz CPU at 4Ghz is pretty good to begin with.

I was going to buy the 975 chip, now I cant understand why anyone would bother considering the price difference.

 

[Gaidin109]

I do believe you. I just miss your last post when I was doing 1024mb to run test.

Anyway, just done linx as following:

Problem size: 25854
Memory to use: 5120 MB
Times to run: 20

Passed after 1 hour, 18 mins and 41 sec !

Easytune6 read as following:

System temp: 39C
Cpu temp: 57C
North bridge temp: 59C
GPU: 41C

Real temp read as following:

idle: 41C 41C 40C 39C
full load: 88C 87C 84C 83C

Are these okay ? As temperature still too high for 4.2Ghz at 1.3125vcore at bios. Not happy about 88C !!!

Also, I got 8 fans in the case Antec 1200. 3 in the front, 1 in the top, three in the rear (2 fans as a push-pull H50) and 1 fan in the middle to cool down ram and graphic card.

Your Northbridge and system temps are higher (not too high) than mine which suggests to me that the airflow in your antec case isnt as good as it should be. Post a Photo of the interior so we can have a look. MIght be able to suggest something to get more air flowing. Also there is such a thing as having too much airflow, one fan could be robbing the air from another. Its no good if the cool air isnt getting to the components it should be.

I got 30c motherboard temp and 43c NB temp.

 

[bulldog147]

I had now done everything but I will fit new fan at the bottom case same as what Gaidin109 did. Here is my photo:

I had applied mx-2 a very thin layer on the cpu with a credit card and put a small dot in the middle on the cpu in the centre before attached the pump on the cpu.

I will do the test tonight. Hopefully I get around 80 degrees or less on the 4.2Ghz. Wish me luck.

Gaidin109: did you overclock straight away or stay on idle for abit longer while before start to overclock after you done all the installed of H50 setup ?

I'm not sure what you mean..?

If you mean have I run my i7 at stock, then yes, but not for long and only while I was researching Overclocking the i7, I bought the 4Ghz bundle, but it didnt come overclocked (OCuk ****-up) and it took so long to get to get the profile that I ended up doing it myself, with much better results I might add from the OCuk profile that was eventually supplied.

By the way, post a larger picture of your case with the airflow marked, like the one I done for you. I cant get any idea of case flow from the supplied photo.

I have just updated the Gigabyte UD5 bios to F9e and it seems to have reduced the vdroop slightly, I have got to do some testing but preliminary IBT is about 2c-3c lower.

although ET6 now reports garbage in the BCLK and QPI speed boxes and thinks I have a Gainestown cpu.????

The update is supposed to fix cpu abnormal temperature according to the notes.

Yeah, but the majority of the time I get any problems I automatically think it is hardware related, but after the problem with LinX last night, I now realize that problems can also be software related.

I have been running my system at 4GHz for the most part, but now that I am going to be putting the chip under water, I want it to be clocked to 4.2GHz, so that is why I have been playing around with it there for the last couple of days.

Running a 2.66GHz chip at 4GHz is amazing tbh, that is a 50% o/c right there!

As for buying a 975, the only thing that would be good for benchmarking for high scores with extreme cooling like Dry Ice or LN2, if you are on air or water I really don't see why anyone would want to buy a 975 over a 920 as they both o/c about the same under air or water anyway..

Even if I had loads of money, I would still have bought the 920 over any of the EE versions..

I see there is a 960 being released pretty soon, someone on XS has posted some benchmarks using the 960 on a UD5.. stock frequency of 3.2GHz, like the 965, but it doesn't have an unlocked multi, and it is D0 stepping...

Here is the thread I am referring to..

24 multiplier is nice, good find. Overclocking this is starting to annoy me, all seems fine for a while then it refuses to post and needs a cmos reset. Only at 4.0 as well.

If having a lot of trouble which doesn't make any sense I tend to blame it on a corrupted windows, knock it down to stock, reinstall and go again. Often solves the issue.

 

[Gaidin109]

Here is an hour of prime blend, with the F9e bios. temps were prviously about 72c-73c with the same ambient and case temps, so seems to be a slight improvement. boots quicker too. I am absolutely delighted with the load temps Im getting now. When I first got the bundle and the ocuk profile my load temps were 88c-90c with the fenrir.

I wonder how Bulldog is getting on with his 4.2oc.?

Thanks for concern of how I get on ? I done the test but sadly temperature went too high same as before, it really annoying me now. Temperature went up 1 degree highter from 88C to 89C now. I had now removed corsair H50 and installed Megahalems as temperature is lots better than H50. Temperature now around 80C using linx with 4.2Ghz. It so strange! as I think my H50 had a counterscrew issue problem.

Here is my new photo of what I did with Megahalems cpu cooler in my case:



Gaidin109, Firmware bios version - is it beta or final release version from gigabyte ? Glad to hear it all work out for you but for me, sadly I had to stick with my megahalems until I sent back my corsair H50 to holland as I knew from counterscrew issue problem.
