A few questions about the i5

I’m going away later this year so am selling my Desktop PC witch 4Ghz QuadCore (OC’d Q9650) and replacing it with an M11X.

I think i’m going to save a few £’s by going i5 over i7. When using throttle stop is there much difference between the two?

I understand the chip is a dual core with hyper threading. Does hyper threading only work on applications which support it or does it work all the time?

I here SETFSB is now compatible with the M11X. Has anyone had experience combining ThrottleStop and SetFSB?

Will the i5 using throttle stop run while gaming at 1826mhz with a multi of 11 of FSB of 166 (If stable) or does it use a higher multi?

Thanks for any help.

EDIT
On a side note I understand the 1333Mhz RAM is limited to 800Mhz. Is it possible to tighten the timings of the RAM to compensate?

 

SetFSB supported the M11x for a long time but only in the shareware version. There is no free alternative for now. EDIT: There now is.

The i5 uses a 12x multiplier with 166, for 2Ghz. Check out the Supercharge i5, i7 thread, CSurfy managed to combine both with an i7.

The RAM is already running at CL6. No point tightening any further.

 

I dont mind purchasing a little software.

So could SetFSB be used to get say 180FSB x12 with Throttle Stop?

Thanks for the reply.

 

Yes, but that overclock is not guaranteed.

 

Also looks like it may crash on idle when the multi jumps.

Ether way 2Ghz should be nice. The review I read of the M11X put it behind the old Dual Core for gaming. I guess with these tweaks it'll now perform better.

 

It crashes because it's unstable with the high multiplier if you're are referring to Csufy's i7 M11x. i5 owners won't be affected by this as much as everything will be lower clocked in general.

I wouldn't regard any performance results in any R2 review as valid- we intend to use Throttlestop to enable much higher performance then the review machines and I haven't found any review testing the R2 with Throttlestop.

 

This is true. Throttle Stop really is a great bit of software.

So I'll stick with the i5 then. Save some cash for my trip!

 

Given the stability issue Csufy has experienced with the i7, is it likely the i5 may actually outperform the i7 when setfsb and ts are set to optimal for overall, (read surfing and gaming) usage?

I admit to being a complete buffoon where oc is concerned.

 

It's unlikely to outperform the i7 as it needs to run at a much higher BCLK to match the i7 clockspeed. Using Csufy's example, he achieves 2.55Ghz by 182*14. In order for an i5 to get the same clockspeed, it will need 212BCLK *12.

Memory and BCLK will the determining factors to stability, both of which very hard to negate- BCLK has a wall ~200-210mhz and the 1333mhz RAM uses CL6 timings, meaning it won't overclock well (~1000-1050). I haven't tested if the M11x R2 can boot at timings higher then CL6.

 

Could you not loosen the timings in the BIOS to give more OC headroom? Also will 8GB make life more difficult?

 

There are no timing settings in the BIOS, you will have to force higher timings by editing the SPD with ThaiPhoonBurner. I haven't had success with that in my time with an R1. I haven't tested 8GB before so I don't know. I do know at CL6, 1066 and 1333 RAM clock similarly- topping off at 1050-1100mhz.

 

Thanks for the info.

 

Thanks Davy!

 

No problem.
