Done, they replace the board
All working as it should be     

rebuild back my system.. early rig was destroy by  kebabom psu

some quick stress testing  .. 50minute

cooler via  air cooler  Prolimatech Supermega dual fan setup 
asrock z87 fatal1ty professional
cheapo ram ...  early ram was destroy too

it okie or fail   any tips for me 

which one better adjust multiple @bclk

- Intel i7-4790, i5-4690, i5-4590, i5-4460 (Haswell refresh).
- Intel serie 9 chipset (Z97).

hi all.. i got i5 4570@3.2ghz using asrock z87 pro3 and gskill ripjawsx 2133 8gb ram.. i know that i cant oc non k haswell but i tried changing the cpu ratio to 33 instead of 32 and i changed blck to 104.2.. i got 3.4ghz and it is stable.. is it ok to do this? is it will damage my proc? sorry noob here.. 1st time overclocking.. thanks

so how high can i go with my setup? currently testing with 3.5ghz and stable so far.. max temp is 70c

Guys, is Win 7 x64 SP1 having prob displaying the correct Haswell freq??   

Owh, one more thing
I cant fix my Bus Speed to 100 even I put manual value & Spread Spectrum Disable
Is that common for Asrock board?

The Z87 KILLER FATAL1TY also runs its BCLK a bit shy of 100MHz, so you will see some slightly reduced clocks when you check those.

What is pointed out above, which is not much, is basically all the "issues" I had with this motherboard.

The OS and driver install were near perfect as noted. It worked exactly as it should and never gave me an issue with BIOS changes or hot-swapping data drives.

Thanks for the tips but is that possible to set the value by 0.1 increment?
I cant test right now coz working, might check up later   

Wow w0ot?! Such nice review almost cannot believe what exactly this board could offers   

owikh84
Ive read over the net, few forum regarding OC not recommended Prime95 for Haswell as they mention Prime95 gone really beyond the limits
They suggesting AIDA64 as it were optimized for Haswell

Wht dya think?

So how bout IBT? It seems that IBT further extreme compared to Prime95
Example, at same setting, my rig fails stressed with Prime at 40 minutes
But for IBT, it seems much faster, at 7th round it BSOD   

Prime is more into power consumption?
That means it stress the PSU as well?
Is your rig passed the Linpack 11?

Ahh ic, in my situation, when I ran IBT, setup 43x100 it could passed
But when I increase the multi to 44x100, it crashed/ BSOD, both are same vCore
This mean I need to increase the voltage right? Btw, does the cache multi affecting our OC stability??

0x101 = increase vcore
0x124 = increase/decrease vcore or QPI/VTT... have to test to see which one it is
0x0A = unstable RAM/IMC, increase QPI first, if that doesn't work increase vcore
0x1E = increase vcore
0x3B = increase vcore
0x3D = increase vcore
0xD1 = QPI/VTT, increase/decrease as necessary, can also be unstable Ram, raise Ram voltage
0x9C = QPI/VTT most likely, but increasing vcore has helped in some instances
0x50 = RAM timings/Frequency or uncore multi unstable, increase RAM voltage or adjust QPI/VTT, or lower uncore if you're higher than 2x
0x109 = Not enough or too Much memory voltage
0x116 = Low IOH (NB) voltage, GPU issue (most common when running multi-GPU/overclocking GPU)
0x7E = Corrupted OS file, possibly from overclocking. Run sfc /scannow and chkdsk /r

Running CPU Cache Ratio faster than processor core frequency does not show any performance gains so we recommend staying in sync with the CPU ratio or within 300MHz (lower than CPU frequency).

Might not be the right place, but since it has some relation to the BIOS update to H87/B85 chipset that enables overclocking of K series Haswell;

i5-4440 in an Asus H87M-E motherboard with BIOS version 0604 out of the box (dated 30/8/2013). Detected as i5-4440 in BIOS, Windows 7 (My Computer -> Properties), CPU-Z, HWmonitor.

Then I flashed the BIOS to the latest one at https://www.asus.com/Motherboards/H87ME/#support to 0904 (dated 17/1/2014). The changes I observed;

Still detected as i5-4440 in BIOS, Windows 7. But in CPU-Z and HWmonitor it now shows i5-4670S.
Still clocked as 3.1ghz with 3.3ghz turbo like a 4440 and 84w TDP, as 4670s suppose to have 3.8ghz turbo and 65w TDP.

Anybody knows what happened here?

what is the common stable voltage for 4770k at 4.5ghz 24/7?
does it need to run 4c/8t?
may i know best batch for this CPU? I need to know as im planning to get 4770k.

Can S, T SKU be overclock ?

S and T cannot overclock.

owi,
link for CPU-Z 168.2 in OP will expiry soon.......
that's the reason,I always upload also to mediafire.

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.

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.

just want to ask, what is the common voltage for i5 4670k at 4.0ghz? does it need to manually set the Voltage if overclock speed at 4.0ghz?
