Intel Core i5 760 help

[bakaaa]

Hi all

I have a Gigabyte GA-H55M-UD2H Intel H55 Motherboard and am looking to upgrade the CPU, at the moment I have a i3 530 Clarkdale 2.93GHz @ 4.00GHz. I understand that the best cpu I can go for with that mobo is the Intel Core i5 760 2.80GHz (Lynnfield) (Socket LGA1156) Do you agree? Can anyone help me with the bios settings to overclock this cpu to around 4ghz?

Many thanks in advance

those boards are great for overclocking i3 (dual core) but the power delivery circuitry is a bit weak to take a quad (i5 750/760) much over 3 ghz if I remember right.
It should be fine with the CPU at stock or slightly over though.
whether you should buy the 760? depends on price, I wouldn't go over 100 as for 245 you could get

and

which would slaughter a 760 at 3.2 (and probably even 4ghz), clock around 4.2-4.5GHz, and leave you free to sell your old mobo and ram which you could probably get about 100 for

upgrade cost after selling old kit: 145

or just enjoy the PC you have, depends on how much money you have/want to spend, and how bad the upgrade itch is.

What games do you play (or apps if you don't game)? also what other parts (graphics card, hard drives etc?) there might be other things which would improve performance more

I have a i5 750 CPU using the same motherboard. Mine is currently running 4.0Ghz stable 24/7, when completeing benchmark testing i take it higher, but the following is exactly what i have set mine to.

Your motherboard is exactly the same motherboard i have so hopefully if you copy my settings then hopefully you will get a stable O/C

Each CPU is different though.

1. Disable the TURBO BOOST facility.

2. In advanced frequency settings menu enable the BCLK (base clock)

3. Now increase your BLCK frequency from 133Mhz to say 190Mhz. This should give you a nice O/C of 3.8. More Mhz in the BLCK will raise the O/C

4. Now we start on your memory find the SYSTEM MEMORY MULTIPLIER (SPD) when you have found that, enter that, if your RAM is over the rated 1600mhz you (if you want to of course) keep it within that figure so you would choose a divider, which in my case and yours would be 8.

5. Now we need to overvolt your system a little. Return to the MB Intelligent tweaker on the front page BIOS, and enter the advanced voltage settings.

6. Make sure the load line calibration is set to enabled.

7. Then underneath that line (CPUVcore) enter to start with 1.35v (this is to start with it may need more of less) try not to exceed 1.425v

8. In the same menu increase the QPI/VTT to 1.37v and then the PCH Core to 1.14v, then CPU PLL to 1.9v and lastly the DRAM voltage to 1.64v

9. F10, press enter and hopefully your PC will boot up with a nice 3.8Ghz O/C

10. Check temps via REALTEMP GT 3.6 (mine is currently residing around 35 degrees, cooling is a Thermaltake FRIO) And check that your O/C has been applied by using CPU-Z

11. Run Prime95 to check everything is working OK, make sure temps are 80 below, mine normally hits 65 max.

Mine is good for 4.2Ghz when benchmarking. scored over 33k Vantage, and just recently completed the 3D Mark11 with everything stock and scored 5468k

Great mobo IMO and Custom PC rated it aswell.

Also just to add the LGA1156 supports a couple of i7 CPUs those being the 860/870, however for gaming, which is what my pc was predominately built for, the 750 or 760 are an excellent choice.

ReAPeR101 thank you VERY much for your reply, very useful. I have a Arctic Cooling Freezer 7 Pro Rev 2 CPU Cooler which I hope will be ok for the job. Trying to buy one new upgrade a month until battlefield3 comes out Next month the video card! Thanks again

 

[ReAPeR101]

Artic Freezer Pro is a good budget cooler, i used to use them on all my system builds, now i have a good search around, read the forums to see what is best and what other people suggest.

If you are going to buy one new then you would be better off selling what you have and swapping to Sandybridge. It's madness spending £160+ on a i5 760 when a 2500k costs less and is faster. Pick one up second hand as you will likely be looking at £70-90 for one. Looking at completed listings on the bay they go for as little as £50 these days.
