thanks. I don't use that many Asrock boards.

I've no problem with MSI / Asus boards. Looks like I'll have to try again.

As you know, UEFI / Manuals are almost never helpful.

shld be same as kmar extreme 4.

so....

just dont do adaptive or offset mode for haswell.

Instant overclocked by: AceCombat, ktek, owikh84 & kelvinchen
Just a fast overclocking, took us about 2 hours to get this done.
The objective is to build a best C/P rig only.

Intel Core i7 4770k @ 5.0GHz
4 cores 8 threads (1.472 vcore in BIOS)
Gigabyte Z87-D3HP
Corsair Dominator 2x2GB 1600MHz @ 2600MHz
Sapphire HD4850
Gigabyte PowerRock 500W
Corsair H100 with 4 fans

SuperPI 32m stabled. Running more tests real soon.
Full size images.

remember cpuz validation

I have no problems with my Asrock Z87 extreme4. Just set the CPU voltage to 1.2v and booted up with CPUz showing 1.192v. You're using the newest CPUz right?

The older CPUz actually showed 0.888v on load and 0.800v at idle.....

Is it with you? Anyway, i got it in my phone.

ur email got ma, just paste the validation link here

using latest. shows me the numbers you mentioned. sometimes 0.894.

i felt it really weird cos the option is there. I set the voltage no matter how it just doesn't go above 1.0

all tried. all fail.

my style of OC is i don't use off-set / adaptive whatever. I prefer just set the vcore. Unfortunately this OCing experience took up 2 - 3 hours of my time.

k. now I'm going to update firmware, just in case it's firmware issue.

Latest version as in 1.64.3?

If I remember correctly, I downloaded the newest from CPUz's website but it is actually not the newest, showing the weird voltages.... It was only when I downloaded the link in the first page of this thread where it showed correct voltages....

Try the link in the first page

ok will check.

my side confusing already.

Asrock UEFI 1.776 vcore = CPU-Z ~0.88 vcore
Asrock UEFI 1.2xx vcore = CPU-Z ~0.64 vcore

cheeehhh vomit blood. so many hours fiddling all because of CPU-Z.

That also I downloaded from the site and installed some more.

In the end had to Google out the 1.64.3 to get it to show the correct vcore.

doing 4.2 nicely now.

Nice chip spotted. Later sure kelvinchen will hunt for a good Hynix RAM to strike for 3000+ IMC.
Looks like you guys had fun with overclocking there. Too bad couldn't join (I chose my GF) =.=/
Welcome back to OC world, AceMeimei

Your OC needs some tuning to make it more efficient.

4770K @ 4.9GHz and RAM @ 2600 10-12-12-27-2T:



4770K @ 5.0GHz and RAM @ 1866+ should yield 6m 20s.

bro owikh84,come to join next time oc project...need your Hynix ......

OK finally got it OCed.

Tested stability with video encoding.

4.4ghz failed no matter how I tried, even with 1.35vcore.
4.3ghz 1.25 vcore = passed.
4.3ghz 1.225 vcore = passed.
4.3ghz 1.20 vcore = failed.

Using the Cooler Master Seidon 120M, AIO WC unit. Testing the product ........ not exactly an impressive AIO setup. I feel that my air coolers can do similar / better. Can't do comparison now cos this ITX board is really small.

Will be getting ATX LGA 1150 board(s) next week so another round of OCing would ensue.

Why video test instead of prime95? I can't get the CPU to run straight at 4.3ghz. Disabling Speedstep / TurboBoost results in default speed only.

Prime95 on the above setting doesn't push it to 4.3ghz, just hovers at 3.8ghz. The video test pushes it to 4.3ghz though.

Now I go do further test. See if Prime95 can push it to 4.3ghz for further test.

*ok I just ran Prime95 Small FFT test (didn't run the suggest test in 1st post cos that one doesn't push it to 4.3ghz) and the AIO WC couldn't take it.

interesting. More interesting when Haswell-E comes out i am jumping on it.

Haswell main market is notebook n ultrabooks. They all going to get a performance upgrade with longer battery life n better graphics with iris pro,
seems to be more or less what kmarc was describing.

Btw i expect some cheating on cpu related benchmarks. Haswell u can change multi n voltages during stress runs. As long the new settings are correct, no issue.

Newest version of prime95 (build 27.9) would be able to stress your CPU adequately as it uses AVX FFTs. However, I found out the hard way that for windows 7, you need SP1 to enable AVX.

You should try linx 0.6.4 (10.3.7) but ensure your rig can run AVX. My temperature almost hit the roof with AVX.



Vcore of 1.100v @ 4.1Ghz already hitting 75-79'c (about 10 mins). If I increase vcore to 1.2v, temps will hit 81-86'c in an instant.

The most I can do with the temperature in my comfort zone is vcore 1.153v @ 4.2Ghz

What's your temp at 1.20- 1.25v?

Dunno how true but this OCN guy said that he got a 4670K Costa Rica batch from NCIX.

Hopefully it will hit our stores soon. Our hope for better chip.

WOW... naked...

Ace.... how much u building w this rigs
