Both are actually same hot. It is not a good idea to compare Haswell @ 5.0GHz with Ivy @ 5.0GHz, considering Haswell has roughly 10% IPC performance gain over Ivy.
Hence, you are going to compare like Haswell @ 4.7GHz vs Ivy @ 5.0GHz.

Today is a rainy day. So sleepy in the office so I decided to overclock my office rig the HP pavilion HPE H8-1340D.

The machine is powered by i5 3570, cooled by Intel stock HSF, and single stick of 4GB Ramaxel 1600MHz C11 RAM:


i5 3570 3.4GHz @ 4.0GHz | 1 X 4GB Ramaxel 1600MHz 11-11-11-28-1T @ 1600MHz 9-9-9-24-1T


Intel Extreme Tuning Utility is used to tweak the overclock.

wtf...you oc your office pc...lol

I also have one HP high-end workstation pc in under my name in office, i7 with 16gb ram... never think to go oc it le

Hehe.. better don't kill it if it's out of warranty already. I have 3 other HPE in my lab with i5 3470 + 8GB RAM and waiting to be tortured haha.

Got bored again today I am working in the lab although it's a public holiday outside lol.

i5 3550 3.3GHz @ 3.9GHz | 4GB Kingston 1333C11 + 4GB Hyundai 1600C11 @ 1600MHz 9-9-9-24-1T

can u over clock a i5-3750?

Do you mean i5 3570? Yes you can, you will need to change the base clock, which in turn will affect you ram frequency.

yes 3570. haha.

base clock? how do i do that?

Before that what mobo are you using? You will need to change it in your bios. Have you done overclocking before?

g77m-g43 msi mobo. nop havent tried b4. haha. still newbie

Here is a guide for Ivy Bridge overclocking. If you go to the first page on this forum, there are a lot of guide posted by owikh84.

Since you using a non-K processor, overclocking will be hard. I'm not sure if you can adjust the multiplier. I suppose the base clock is the only way to overclock a non-K cpu. Read the guide and ask more on what you are not sure of.

ok i will cheack it out! thx!

3570 can overclocked? wihout a K

All the non-K i5 and i7 can go up 4.0GHz and is essentially just changing the turbo. Normal turbo speed for your CPU on all cores is 3.6, but will be 4.0 if you set a 42 multi. 4.2 will be for 1 core.

is it eas to overclocked? mine now is 3.4ghz

Overclocking through BIOS settings is as easy as ABC.

haha i didnt really explore the bios seting yet.

Hi guys, new oc-er here. Here's my first attempt on oc my i5-3570k 3.2Ghz to 4.2Ghz. I'm using Intel Burn Test to test my stability. Can push it even more?
Is Intel Burn Test enough or I need run Prime 95 24/7?

your temps looks good for higher OC.
Try 4.3-4.5GHz and see if your cooler can still take the heat.
As for the stress test it's all up to you. Of course the longer the test the more confident you are in your OC.
But for me, 20 runs of IBT or LinX are more than enough.

Alright, u think it's possible to use the same stock voltage while oc-ing it up to 4.3? Cuz I'm using offset -.050v at the moment for the 4.2Ghz. Using custom wc to cool things down atm so I think should be able to handle it?
