I've just setup my new motherboard & chip, 2500k and AsRock Extreme 7 Gen 3. I would like to overclock to 4ghz maybe 4.2 and have no idea where to start.

My previous experience has been overclocking AMD chips on the old BIOS type. This is the first time I've used the BIOS.

I have increased the multiplier and that is about it. The turbo ends up being 4ghz, but that is the extent to my knowledge on this platform.

Would someone be kind enough to give me some details on how to achieve this please?

If your wanting to go to 4.0 on the chip this generally needs no voltage increase in most chips.

To achieve it simply go into bios and change the multiplyer to x40 and test you don't have to mess around with anything else.

I was unsure if it was that simple. Will try it and see how I get on.

Should I leave speedstep enabled?
 
Hey mate, that K2 is an awesome cooler, you can easily get 4.5 out of your chip safely. :)

a lot of people say use offset voltage as it only ups your voltage when load is applied but this is quite un-stable (especially on my rig), i have to up the volts more for it to work on offset that fixed voltage.

What i'd do to start with is go fixed voltage. Remember upto 1.4V is the safe zone. :)

What you need to do is:

  • Disable all C states (including speedstep)
  • Set multiplier to x45
  • Disable Turbo
  • Set voltage to 1.3v fixed (this a good starting point)
  • LLC to high (i think those settings are on that motherboard)
  • VVT to 1.1v

Then give it a run in prime 95...

If i t fails up it to 1.31,1.32,1.33 ect (or something similar)

I can get 4.5 stable on 1.3 pretty easy. If the D14 can handle it so can the K2. :)

My LLC is showing in levels. Level 1 through to 5.

Ah, like how mine works though I have 1-10.. Id go for level 2/3.. :)..

Level 1 under volts, level 2-3 gets volts as near to fixed as possible level 4-5 will/may overvolt. This is to what you set, so 1.30 on level 5 may become 1.33 underload, where level 1 1.30v may be 1.26 under load.

Currently running @ 4.3 on stock volts with Speedstep & C's disabled. Had a round on BF3 and rock solid. I'm so overwhelmed by how nice this chip is compared to my old FX.

Glad to see your a convert. :)

They are insanely easily.

4.3 is great, I only managed 4.2 on stock. Give it a bit more of a push. :)

Well I've got to go and collect my bike for the Cycle2Work so for the next 30-40 mins, prime95 can tell me how stable it's going to be.

Wish I'd gone Intel sooner. BF3 is lag free when loading and everything is so responsive. My only learning curve now is the new BIOS.
 
Good times. Let me know how it goes. :)

I know right. :)

Im not a fan of these fancy bios' they look shiny and confusing. Give me 90's bios any day. :)

sorry only just got back on the comp.
loooks like u have got some good info though,whats your ideal speed u want to get to? or are u pushing to see how far u can go?

It's been running Prime for 75 mins at 4.3 on stock volts. Will try for 4.4 and will be happy there.

under 1.4v.

If custom watercooled you can get away with pushing it to 1.45v

Benching, 1.45V (non-WC) - 1.5V WC

@snips: How did your Overclocking go buddy? :)

Still at 4.3 and stable on stock speeds.

Will push again later on this afternoon after I've managed to work out why my PC won't boot with my external drive connected. I got a feeling there's a wiring issue which may explain why my USB3 ports on my old board no longer work.

As soon as I can get this headache out the way, I'll aim for 4.4/5. So far so good and seriously impressed. I know I keep saying it, but it's great.

Off topic, any reason why I cannot get into the BIOS with my Logitech G510? It just doesnt respond to the F2/DEL option and I have to use an old USB K/B to get in.

Some strange issues there. I found that in Far Cry: BD my PC crashes if i remove my controller. It doesn't happen in any other game just that one. :)

Anyway, I assume you've tried different USB ports for your external? Have you tired a different hard drive?

Is the keyboard plugged straight into the PC or through an extender of some sort? That keyboard may have settings which may fix that issue.
 
So my wife has reported some teething issues:
- Windows update failed to complete and forced an unexpected reboot
- Keyboard then failed to respond and attempted a windows repair after booting to safe mode.

Despite being fine in Prime/BF3, there is obviously some fine tuning required.

vCore set to 1.3, LLC set to Level 3. Still running @ 4.3ghz and seems to be ok after 20 mins of prime, windows updates installing at same time.

What doesn't help is Windows failing to activate online, keyboard doesnt work in BIOS despite legacy USB being enabled. :(

On the up side, my other HDD works fine using the same cable & power adapter.

you can activate windows over the phone,pull internet wire from pc and activate, it will then give you the by phone option

badly crashing usually kicks windows into wanting to be activated again

with 16gb of memory try a touch more cpu/vtt also,maybe 1.10v from stock 1.05v

Yeah, it's my initial annoyance at having to move the phone from the lounge to the bedroom when it's not easily accessible.

The activation was due to a re-install of the OS, something I was trying to avoid.

CPU has now manually been set to 1.3v @ 4.3ghz, LLC to Level 2. Will run Prime while having tea to see how it goes.

Really appricaite your responses guys, this is such a learning curve with moving to a more 'modern' system. It's so alien compared to, as Doom said, a '90's BIOS.
