Very disappointed at hyperthreading. First time to OC. Help

Before I got this Acer Aspire E14, I was reading articles about i3s superiority over AMD cpus because of Hyperthreading Technology's presence on Intel cpu for 2 years.

But what the hell when I got this laptop with i5 4210U HT enabled, it's lag and slow on switching from windows to windows. I play this online game (https://www.youtube.com/watch?v=6OnXidh1i14) which needs Pentium 4 2.ghz and Nvidia gt 8800. As I play it on my laptop, it's graphics is glitchy, kinda slow. And when I switch to Google Chrome from my window-mode online game, it slows. Also, When I was creating an avatar, or creating appearance of my character, THE GAME CRASHED (not responding), which I didn't experience on my desktop. My CPU of desktop is much reliable. My 3-year-old Athlon II x3 450 @3.2ghz is very much noticeably faster than my i5 4210 HT Enabled ~.~ I expected too high on this HT. I thought it's good at multi-tasking.

I'm planning to OC this i5 4210U (turbo up to 2.7ghz from 1.7ghz) to only at least 2.0Ghz to make sure it's safe. Is it possible to oc this to only 2.0 or 2.1ghz??

I havent OC before, how to overclock?
What safety measure do I need to take?
And what should I NOT DO?
Do I need to buy laptop cooler?

(Off topic: What's the difference between i3 laptop cpus and i5 cpus when i5 cpus have dual core only?)

Is everything else running as it should be? What do you see in the Performance tab in the task manager at idle (nothing running, all windows closed)? There may be some process in the background eating up those CPU cycles and causing slow behavior and instability.

You really can't overclock on a laptop as their power supplies are rated exactly for what is in the machine as it comes. The cpu is most likely not your problem, it sounds like the graphics card is either garbage or you need software updates. The I3 is generally dual core only without hyperthreading and uses less power, The I5's are usually quad core or dual core with hyperthreading (simulates 4 cores)

The 'U' at the end of that processor means 'ultra low voltage', that processor was designed for ultra notebooks, meaning thin, light & LONG BATTERY LIFE.
This also means that most likely the laptop you have has no real graphics power, therefore lousy game play. That laptop was never designed to be any kind of gaming laptop.

Turbo boost means the CPU automatically clocks up on demand (and when it has thermal headroom - safe temperature and power levels) to the max speed listed (in this case, 2.7 GHz) on one core, and slightly lower speeds on multiple cores. It's automatically managed by the CPU and only runs for short bursts, unlike a sustained overclock.

Agree with the above that this isn't a high end CPU ("U" variant of i5 as discussed) though I still want to make sure the OP doesn't have any other software issue. So is there slowness elsewhere or unusual activity evident in the task manager (under "performance")?

There's nothing running on background, this is new laptop. Not much apps installed. This laptop is supposed to be Win 8.1, but running 7 instead.
I opened the Processes and the game is 700,000 K. Chrome has over 100,000k. Others don't exceed at 10,000k.

All windows closed (except 1 tomshardware.com reply chrome window) ~ When I closed all google chromes, these chrome.exe*32 (7 of them) wasn't remove. 69,000k, 37,000k, 59,000k, 40,000k They were not removed. Nothing else. Why aren't them removed when I closed the entire google chrome??

Under Performance, the CPU always at 50% when playing. Physical Memory reached the peak of 97%. My Aspire has 2GB ram, planning to upgrade it, will it speed up my system anyhow? When I open more windows, will it not slow anymore?

MY GPU IS INTEL HD 4400.



Yes I was not expecting any much on this laptop's GPU, but I expected more on the CPU, I did the "alt+tabs" to change from this Online game to Google chrome, Since this has Hyperthreading technology, I would expect no slows on switching.

So.. Hyperthreading doesn't increase the efficiency of my i5 when switching windows?

Ahh okay. Well I thought this laptop can be OC'ed manually. I don't need battery life. Anyway, if I upgrade the ram to 4 GB, will it somehow reduce the slowness?

ONE MORE THING::: Flickering

I see some horizontal flickering on the background. But when I opened up a google chrome (white background) it disappears, but the background has flickerings.

HOW CAN I DOWNLOAD THE INTEL HD 4400 SOFTWARE UPDATE?

Hyper-threading is a clever trick by Intel that makes one core work like two but not as fast as two actual cores. As to this specific case, the high load in one window may be the issue. Since this game is 1.older and 2. played i a browser it probably can't use more than one core which means hyperthreading isn't relevant at all. What limits you would be the low sustained clock speed. Turbo boost won't help much either, since as discussed above it's for short bursts only. You have a 1.x GHz sustained speed on one core here. Even though that core is more advanced and efficient than the Athlon core on your desktop, it's hard to overcome that big a difference in frequency.

Does this flickering happen constantly or only in this browser game? The latest driver should be available from Intel support website

That will be about as helpful as downloading a new laptop.
