Just de lidded my 3770k

i believe for intel burn test to work properly there has to be more than one run as the outputs are compared to deduce the system is stable

i will have a go after i have finished prime, ty for pointing that out

Muel said:
When you say de-lidded, do you mean you removed the lid completely and bolted the cooler directly to the chip, or did you replace the stock compound with better stuff?

replaced stock ***p for liquid pro and refitted IHS

so max temps after 10 hrs prime was 75c but i had to up the vcore to 1.424v.

gonna work on my turbo volts and current limits to drop volts

you wanna be carefull how far you push voltages,it might degrade the cpu,temps are fine but personally i wouldnt go above 1.4v cpu voltage

you are right, i have dropped to 4.7GHz 1.33v, i didnt see the point in 100MHz and 0.10v MORE :eek:

Very nice results.

For IBT, as above, you'll want to do at least 5 loops, and you could do as many as 50 if you wanted to be certain.

Setting memory to "max" is good as you're getting close to peak performance of the chip which would be 32*4.8 = 153 GFLOPS. However the 111 GFLOPS in the previous screeny is a little low, probably just because it's the first run and hadn't got into the swing of it. You really want to see about 80% of max, or 123 GFLOPS.

Doing more runs might make it stabilise at 123 or more, but if not it might be paging, in which case you should set it to custom and use a bit less than max memory until you consistently see 123 GFLOPS or more.

IBT isn't as easy as just pressing "run", but it's extremely powerful.

will do but where did you get 32 from? now im at 4.7 should i be looking at 120 / 150 gflops?

would you think this would be worth doing on my 2700k??? opinions please. i would'nt mind having a go if worth it

hell no you will kill your cpu!!!

buzzlightweight · 3 Aug 2012 at 17:13

Ok so more than happy with temps

but my gflops are low, how can i rectify this? is there anything wrong with my oc? prime and ibt are stable?

buzzlightweight · 3 Aug 2012 at 17:37

H100 with corsair HP SP air fans

MADMAN said:
nice was wondering why the temps were low

Those fans go so well with the H100.

Reminds me I got my H100 here hopefully the pump is fixed in this one !

because i took the IHS off the CPU and replaced the ***p intel put underneath with liquid pro.

So this is the knife i bought -

it has a very thin blade but still there was only one corner i could get it under to begin with, once it was under i down to the next corner, to the next, to the next.

This were my tools of mass destruction! lol

This is what it looked like once i got the lid off but thats not the end of it

This is what it looked like after a long time spent cleaning it, the silicon is a biznitch to get off the IHS

I used my finger nails to clean off the silicon, it was too dodgy with the knife, it just took a while

If you take a look at where the notch is for the socket locator, notice i did nip the pcb

luckily it was the very edge!

wow very brave ! id be so scared lol id live with the high temps

trust me a steady hand and patience is all you need, even 4.8GHz @ 1.42v didnt go over 75c after 10hrs of prime

Reagrding GFlops in IBT.

Disable HT and manually set the threads to the correct amount.

HT gives poorer results in IBT.

ok ty sin

is the 3820 soldered?

only ivy has NOT been soldered!!!!!!!

Makes you wonder. a £3 job makes the chip work properly. What's Intel thinking.

Maybe along the lines of 'whatever'.

Special '3790K Overclock MGHZ' edition? tsk tsk... Solder that thing!

true dat!

sadbuttrue said:
Based on the number of failed attempts, it averages slightly more than a £3 job

lol people need more patience and a steady hand!

wazza300 said:
haha a £3 gamble more like,probably due to cost they use the cheapest thermal paste they can get their mits on?

i think it is all down to cost and they didnt want ivy to out shine haswell which i think it will

haswell is all about the igpu!

After changing my motherboard it meant that I had to remove the 3570k that I de-lidded. I was surprised at how staining the liquid pro has been.
I had use it on both surfaces of the IHS. The copper bottom of the CPU cooler was quite stained and patchy and the lid of the CPU has stained so that you couldn't easily read what is written on it. The underside of the IHS (above the core) is discoloured slightly.
It took quite a bit of work to get the surface of the CPU cooler to be stain free again, I was surprised at how much it must have penetrated. I thought that it didn't have an adverse effect on copper..?

I have removed the liquid metal now (too messy to apply easily) and instead used this...

https://www.overclockers.co.uk/showproduct.php?prodid=TH-000-GD

...it is very easy to apply and the overall temps seem about 3 or 4 degrees higher at most.

The liquid metal pro is a superb TIM in its cooling capabilities but in use it can be difficult to apply and if you should ever drip a small amount on your board you can have real trouble in removing it. I was quite enthused about it at first but I just couldn't see myself using it again.

well i have a tin of brasso and a tin of elbow grease ready if i ever need to remove my cpu :eek:

thanks for the heads up on the Gelid Solutions i will keep that in mind but i have to say i am taken by LP

buzzlightweight · 5 Aug 2012 at 17:06

Even Stulid said it was a great TIM the only draw back is the amount of effort needed to clean it up.
For regular users who will not be de lidding i recommend a std TIM like the Gelid but for those who seek a drop im temps by de lidding i recommend LP, as shown in this thread the temp diff between MX4 and LP under the IHS was very very noticeable!

buzzlightweight said:
OMG liquid pro FTW

CPU Cooler H100, 10 mins of prime @ stock, Liquid pro on CPU and IHS (UNCURED!)

CPU Cooler H100, 10 mins of prime @ stock, MX5 on CPU and IHS

CPU Cooler H100, 10 mins of prime @ stock, MX5 on IHS only

tell me this is not the best results!

MX4 / LP / Difference

core 0 44c 39c 5c
core 1 43c 38c 5c
core 2 45c 36c 11c
core 3 46c 39c 5c

those few degrees can mean a lot to an OC'er

buzzlightweight · 5 Aug 2012 at 20:06

i bought this, but you can get a smaller tube, demo kit, this, i was in no way referring to Liquid ultra!!
