i5 2500k help!

post #1 of 3
Thread Starter 
Hey guys, just got my new rig set up today.
System Specs:
i5 2500k
Patriot Sector 5 1600mhz ddr3 16gb
Asrock p67 extreme 4
gtx 260's SLI (for now)
corsair gs700 psu

I have some overclock questions and such about my cpu and memory.

Here is a pic: Warning: Spoiler! (Click to show)

My question on this one is:
it says the core speed is about 1600mhz and the multiplier x16.0 , this jumps back and forth between 1600mhz and 4000mhz as well as x16 multiplier to x40 multiplier. Is there any way to have the cpu running at a constant 4000mhz and x40 multiplier? The system lags and freezes up sometimes, not really seeing a huge performance increase from my last AMD a8-3850. Please help with any tips on making my system run faster and smoother.

In this one it says my memory DRAM frequency is around 800 mhz. I dont get it because my memorys stock speed is 1600mhz. What do i change to make it run at a constant 1600mhz?

Here is the last pic. Just for references: Warning: Spoiler! (Click to show)

One last thing. Im running two gtx 260's and sometimes one of the cards( the secondary card) just shuts off, like the fan just shuts off . Is this like loss of power or something?

All help appreciated. Thanks

That's just how these Sandy Bridges work. At idle the 2500k is at 1600MHz to save power / save energy / produce less heat. When you start a program or a game it will go up to what ever clock you are at (either stock 3.3GHz or the speed you have OC'd it to). You can turn it off in the BIOS if you wish (should be called Intel Speedstep).

I have DDR1333, and CPU-Z says my DRAM frequency is 666MHz, so 800MHz for DDR1600 is completely normal (read: correct).

I really can't help you with the graphics card shutting down though though, as I'm not familiar with multi-GPU systems. But my guess is that it's something else than the PSU (700W should be enough). But my wild guess is that the cavalry of overclock.net is coming to your rescue soon. wink.gif

Ahh I see. Well ever since I wrote up this thread, I have been playing a few games and running some benchmarks and I am very impressed. I think im going to leave the Speed Step on because its just great. I did overclock my 2500k to 4.0ghz with some feature in my BIOS. This thing is very impressive, I love it. As to the graphics cards, I narrowed it down to a faulty sli bridge. When i had the sli bridge between the two 260's i would get screen tearing, discoloration, and random shutting off. But when I removed the bridge its running like a champ. Guess i just received a Piece of Sh** bridge from ebay. Oh well, the graphics cards run fine without the bridge in SLI. And im very impressed with the performance I'm getting with such old cards. Just put my order in for a XFX Double D 7970 biggrin.gif so I think I will receive even better performance with that, along with better power consumption and less noise/ better cooling.
