Hi, OC'er here.

Just built my half new rig yesterday.

1. i7 4770k batch L344C551 Malaysia
2. Giga Z87X-D3H
3. Kingston HyperX Beast 2400Mhz CL11 8GBX2
4. Corsair H110 LC
5. Corsair 500R casing
6. SILVERSTONE Strider Essential series ST60F-ES 600W (9 months old)
7. Asus HD6870 1GB (9 months old, after RMA 2 times)
8. Kingston SSDNow V300 120GB (reused)
9. Creative X-FI Xtreme Music

Choose this mobo mainly becos it has PCI slot for my old sound card, and i dun need those fancy gaming features in those gaming/OC board. Weirdly Gigabyte become very silent when comes to Haswell platform while it been dominated by ASUS. Hopefully this mobo can give some solid OC performance.

Quick test, stock i7 running IBT, around mid 50-55'C, 3.9Ghz at voltage 1.11 (High voltage or not??)
Tried quick OC without change voltage setting, 4.2Ghz boot into Windows, quick run IBT for 5 minutes no crash, LinX after 10 minutes system restart. Will try to do some serious OC after i update my board BIOS. Target at least 4.6Ghz.

Anyway, any place in KL provide 'professional' delid service? Or we have to do our own? May I know who done it here?

Yeah, that one is full load temp, i set IBT @ 12GB RAM test.

i set at max fan and bump speed all the time, becos not really that loud actually.

I plan to delid myself using razor blade, should be not so difficult. Just need to watch out the tiny cap at one side.

Anyway, is it OK if after delid i just run it bare chip without reinstall back the IHS??

Huh? I search forum alot of modders run without IHS, no?

Thanks for your wish.

Sad OC result. Don't know whether due to cooler no sitted properly or what. 4.4Ghz with 1.25Vcore CPU already start throttling.

In stock, temp delta between idle and load is too big, which is around 45'C. Load temp during LinX is from 70-85'C, However when i touch my H110 radiator with hand it actually just slightly warm only. Just feel the heat just trap inside the IHS...if really no improvement after i resit the cooler, might as well consider delid the damn thing.

1.2v i can boot into window but once linx started, the pc bsod...so i just set to 1.25 without test other intermidiate vcore...

Resit my H110 cooler today, still the same, the temp is very high at load even on stock frequency and voltage.

Stock temp idle 33, load 75-80. Delta over 40'C. Is this normal? The thermal paste used is Cooler Master X1 Extreme Fusion.

Back in core2 era, OC is just a simple task for me. For this Haswell I have absolutely no idea for it, it just like a stranger to me.

day 3 i OC my CPU, i understand something from the sensor.
1. memory voltage 1.65V will absolutely increase the CPU temp, hence those performance RAM is actully can run at tighter timing and faster clock with lower voltage (ex 1.5V), am i right?

Anyway, i really feel disappointing with the temp, although sensor reading is 90'C, but the heat cannot transfer to the cooler, just waste my cooler capability.

Actually i have no plan to OC RAM, but well, running my RAM at 'default' 2400Mhz already mean i OC from Haswell point of view.

Regarding temp drop after delid, -30'C is just an absolutely best case can achieve, i doubt everyone delid can get the same result. I search the forum, mostly drop around 10~ 15'C only, correct me if i'm wrong. I just worry lesser gain when i delid (<10'C drop), not worth if like that.

Anyway, yesterday i got frustrated by the result, so i pump 1.4v and clock to 4.7Ghz, can boot and running GRID 2 without issue. Today will try to hit 5Ghz with this voltage.

Yesterday just bought a table vise. Now waiting for that moment of indiscretion then will do it....maybe a year later . I will buy G3220 as a backup before i do it. Now just settle with 4.3Ghz with 1.22V.

Anyway, read the forum about temp reduction after delid, it actually depends on originally how loose the contact in between IHS and die, if the gap already small, delid and reapply TIM might only give 7-10'C reduction. 30'C just a rare case.

U, no doubt about that.

They will released 'OC enhancement' Haswell by mid year, they will 'improve' TIM for this unlocked chip, seems like maybe they back to solder TIM...

This is my final OC result, i think i will settle with this speed. Only validated by AIDA64, LinX, IBT, Prime95 result will no doubt out of the question and i dun need that as well. Will try and see stability during daily usage/gaming.

If this new i7 4790k can OC to 5.0-5.2Ghz on AIO over my 4.5Ghz 4770k, do you think worth to upgrade or not??

The released 4790 is non k version, so can't overclock.

i7 4970K Review by Tomshardware.

Same voltage, same clockspeed, the so called Next Generation polimer TIM only 6'C cooler than 4770k crap TIM? What a joke.

Might as well delid the damn 4770k rather than 'upgrade' to 4970k.

Have u try upping ur VCCIN? Put ur Vcore at 1.35v ceiling (1.44v is too high already), up ur VCCIN and enable LLC to highest setting VCCIN can try until 2V (default 1.8V, but will register as low as 1.65-1.7V if LLC is disable). How about uncore multi? Try x40 or below when ur OC reach 4.5Ghz and not stable.

Why the majority 4790k reviews that i read all praise on the 'new' TIM but in fact it only cool down to 4-6'C when head to head comparison (same clock and voltage)? They self satisfy or what? In fact a delid 4770k can give 10-20'C improvement? They tends to forgot the solder is much better than that.

Hi, anyone here delid using hair dryer + vice method??

Just order CLU, tomorrow night gonna delid by using hair dryer+vice method, wish me good luck.

Hi, yes, this method is relatively easy.

U should untick stress CPU, instead, just stress FPU, From your temp reading in CPU stress mode, i bet FPU stress will bring your setup to 85'C+
