I have recently bought a 3770k to replace my 2500k. When I tried to overclock the cpu via the clock ratio, it wont let me surpass 39x (3.9Ghz). I have a few questions in one.

Firstly if I change to ratio to 39.... will the CPU boost above this?, i dont think is it from the benchmarks I have been running?

Should i just overclock the BLCK? (I have no experience in doing this, so advice would be appreciated)


Any help on what to do next? and why it is only letting get to 3.9?

NOTE : When i had the 2500k, on the same board, it could set the clock ratio to whatever I liked :(  help ?


Can provide Pic's if needed...

You may need a bios update , what motherboard do you have ?

There are two ways to overclock , clock ratio and BCLK and you can use one or the other or both, Clock ratio is the better way.

The boost should be turned off when overclocking.

What motherboard do you have?

The chipset drivers may also need to be updated.

What revision is the motherboard? 1.0 or 1.3?

Even when you get this sorted out your going to find that the i5-2500k will overclock better then the i7-3770k. It's well known that the Sandy Bridge CPUs as a whole overclock better then Iv Bridge.

I'm sure the 3770k overclocks better then the 2500k...

Its revision 1.0

The i5-2500k works great with the Z68 chipset motherboard, while the i7-3770k works better then the Z77 chipset motherboard.

You will get better results if you have a Z77 chipset motherboard.

That's not necessarily true. Plenty of people have good overclocks with Ivy Bridge and Z68 motherboards.

Overall, the 2500K will hit higher clocks than the 3770K. Not sure where you're getting your information from.

Okay, so, when you got the bios, you did get them from the GA-Z68X-UD3H-B3 (rev. 1.0) page? (http://www.gigabyte.com/products/product-page.aspx?pid=...)

Also, are you willing to try the beta bios?

Finally, after Googling a bit, it seems like only Gigabyte 6 series boards have this issue. (http://forum.giga-byte.co.uk/index.php?action=printpage;topic=8761.0)

I'm not looking for a huge over clock any way.... I think were going off topic. Do you think the solution is to get a z77 board then?

I had the money so why not... Your probs right but I'm not going to cry over it.... At stock speeds its faster, that makes me happy. I loved my i5 but I wanted a change and I had the money, I wanted to slash some cash :p

If you want to go ahead and get one, do it. If I were you, though, if you're going to get a Z77 board anyway, you should try the beta bios.

Hmmm...good idea. Have you heard of this problem before?

Any Z77 boards to recommended

Not until I researched it for this thread, but people were saying that Gigabyte was going to release bios revisions that fix the issue, and the beta bios might be that. While, personally, I don't use beta bioses just to be safe, if you're going to get a new mobo anyway, it can't hurt to try.

Recommendation depends on your budget for the mobo.

Okay I've had a relay from gigabyte tech support. They gave me a very blunt response, telling me to update my BIOS.

I'm gonna give it a try and I'll post the results

Do you think I made a bad choice choice upgrade from i5 2500k, although I did sell it to a mate for £100?

I woulda kept it. It's still a very good processor. Unless you needed hyper-threading for something, it wasn't necessary at the moment. Don't worry about it, though.
