help overclocking i5

Ok i am totally confused when it comes to overclocking I think i can do it from my desktop using a program called turboV but I have no idea how to go about it.

The image below is normal when I load it

This image is when I choose the ultimate profile but I dont see any change apart from the first one? does anyone know what Im supposed to do here?

it boosts your fsb to 140 from 133 so 20x140 = 2.80.. instead of the 2.66 stock

use CPU-Z to see the change, saying that i wouldn't class 2.8ghz from 2.66 an 'Ultimate' Overclock lol

Thanks do you think I'm better doing it through the bios then rather than on windows?

hi i have a question too.

i have overclocked my I5 to 3.3 Ghz

what sort of temperatures should i expect when its under load?

ps i only have the stock cooler so i am not leaving it overclocked!!

but when i do test it hits 70c pretty quick !

i have ordered a cooler and just wanted to know what temps i should be aiming for?

Personally I dont like it getting much over 70, but thats me

can probably go upto about 90 before risking damage but most people play it safe and keep a good bit lower than that. I'd say keep it under 70C

What cooler have you ordered? The stock cooler is useless so good work getting an aftermarket one.

And back to Munger, overclocks are always better done in the BIOS. Windows overclocking is a faster as you dont need to restart your PC everytime you want to change something, but when fine tuning BIOS is best, plus much easier to get stable and more options to help you get it stable

thanks will go find a guide tommorow and give it a whirl

at 3.2 I was hitting 72 on core 1 and 68s/69s on the other 3 cores after around 20 mins with a Corsair H50, 1 fan on intake/push/default thermal transfer material that came with it.. [edit] I forgot, this was with the fan at les than half the max rpm, didnt test with it at full whack. No doubt that would have crept up more over time but the rate of temp increase seemed to have slowed at that point.

Planning on putting in some AS5 or MX3 when I can be bothered to pull the cooler off.

I'll probably test it again with the fan at max rpm in a moment

[update]
With the stock H50 fan at full whack the temps seemed to have topped out at 59/54/54/54 (only after around 25 minutes of prime though) and arent going up as when the fans were on low, hope that helps.

The sticky in this forum is a really good starter guide to get you going in your bios. Worked for me and I'd never OCed before.

Basically, drop your cpu multiplier down low, then just up your fsb until you start getting instability in prime95 tests. You then know how high your fsb can go on stock volts. Then up your cpu multiplier until you get stability problems in prime again. Raise vcore a bit at a time (or drop your fsb a bit) to get it stable and continue upping fsb or cpu multiplier, adjusting vcore as needed to keep it stable, until temps prevent you going any further. After that you can mess about with fsb settings to overclock your ram by upping dram voltages and NB voltages if you want to push it a bit further.

Actually, just read the sticky, it's much clearer.

can any recommend a decent cooler??

i have no desire to really OC past 3.4ghz

i thought i had ordered one but never went to checkout!!

but now at least i can get some input

What sort of budget do you have? Its pretty much a case of the more you spend the better the results.

Best bang for buck (or at least Im led to believe that) is the Titan Fenrir, this week its just under £30.

Not really sure on any much cheaper than that, but if you want to spend more, look at the Alpenföhn Brocken (£37), Thermalright Ultra-120 or Thermalright IFX-14 (both £43) or a Prolimatech Megahalems (£50), though some of the last ones need you to buy fans as well which ups the cost even more!

But yea, all depends on your budget, there probably are good coolers available for less than £30, Im just not too well read on them sorry

Regarding the overclocking I use Corsair memory with XMS profile. With XMS enabled the memory rises to 1600mhz from 1333 and the CPU is capable of 3368mhz or even 3840 depending on how many cores are in use (the multiplier ranges from 21 on load to 24 (bus speed 160). Using an H50 the temp stays cool.

I don`t see the need for overclocking with my setup. I`ve tried the OC genie on my MOBO but that only gave me 3315mhz at 195*17...and it didn`t seem to go higher even under load.
