on a more depressing note, I can't even get my vcore to go above 1.000v with this Asrock Z87E-ITX.

Spent some 30 minutes or more with the interface with no luck bumping vcore. Probably one of the worst UEFI / BIOS i ever use.

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.

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.

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.

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.

oh like i mentioned, i use Small FFT settings. Prime95 stresses the processor adequately.

yes, downloaded from 1st post.

I'm using Windows 8 though.

donno. i see temps going beyond 80c, so i didn't continue with it.

aiyah this owikh84 - i thought put CPU-Z to proof ownership only.

nah, 4.3ghz clock image for you. hehe.

if yours is average then mine sucks.

I can't get to 4.5 with 1.25v.

looks alright. It's better than my chip.

need you to explain a bit for my understanding.

why is it considered not successful?

wouldn't that be more like not-so-optimal? because he did reach 4.3ghz and looks stable.

and why is it you say that it's throttled?

and so you determine throttle by LinX Gflops?

interesting. your definition of "not successful OC" is very strict.

my definition of fail is can't reach OS and can't run decently stable. i see his, can run 25minutes LinX i would consider successful already.

sorry ah, not so advanced in OCing so will ask you Q.

from his screenshot, how you see it's throttled? Based on LinX Gflops?

my unit reached 4.7ghz at 1.35vcore but can't even run my video encoding test.

4.6ghz seems to be stable at 1.3vcore.

ES. Findings are like what you saw on the other sites.

Hopefully retail units would be better.
