Is it advisable to turn of turbo boost?

[markvis14]

Hello,

I've done a mild overclock on my i5 2500k processor. I simply changed the multiplier to x44.

Should I disable turbo boost in my bios? And, or, maybe think of anything else?

Thanks in advance.

Has it held out under a lengthy burn in test?

Hi Qdos, what tool can you suggest me? Also another thing I noted, I am noobie at this.. but my memory dram frequency is at 668.7 Mhz

I guess that should be higher right? Assuming it originally runs @1600Mhz?

I ran Super Pi a few times and that went fine.

Have a look at the thread below

It sounds like you have your multipliers set incorrectly for your RAM, assuming your motherboard supports a bus speed of 1,600Mhz - so I would definitely adjust that foremost.

Thanks Qdos, this will help me a lot. I only just got this system, build it myself. I've looked around and between 4.4-4.5 Ghz should be fine with a i5 2500k. I am not using a stock cooler so temps should also be fine.

Okay, so I am a bit confused with what I should set my system memory multiplier at.

I can pick between:
8.00
10.66
13.33
16.00
18.66
21.33

I've tried 16.00, then it shows as 1600 in the bios. But when I go into windows it tells me it runs at 802Mhz (9-9-9-24)

 

[Qdos]

If it's dual channel RAM then 800Mhz would be right...

It's double data rate RAM (DDR). 2 x 800 = 1600.

800 is what you should expect to see.

Hey guys, thanks for your replies.

I changed everything back to default. When I look in CPU-Z my ram shows as 668.7 MHz
Check the screenshot:

My ram is 8GB DDR3 Ram and should be running @1600Mhz.

But like you are saying its dual channel so it should be fine?

Dual channel ram will show clock speed 800.mhz each which will total 1600 mhz with the sticks each running at the suggested speed

if you up the ram frequency to the 1600mhz that will help you OC better and give you more room to play with

If you are new to this though ,I would read alot more about the multiplyer fsb ram timmings they all co exist to help the OC experience better

there are members here with much more experience with Intel over clocking

Just remember not all settings will be the same as others different systems different behaviors and block walls of overclocking

That test won't exercise turbo-boost. Turbo-boost only comes on for a core when some of the cores are idle. Prime95 usually pushes all cores at the max., so turbo-boost won't activate.

If it is a mild overclock, then you are probably OK.

Yes it's advisable and if you decide to push your clocks to 5ghz then disabling HT is also advisable.

 

[markvis14]

It's not an i7 Simmo, so it doesn't have HT.

Thank you all for your help, I got it running stable at 4.5
