Hi Team,

I am looking to upgrade my CPU from i5 2400 to i5 3470. The mobo is P8P67 Pro Rev 3.1. I have noticed something about these CPUs, the Graphic Base Frequency.

i5 2400 @ 850mhz
vs
i5 3470 @ 650mhz

I'm trying to understand what is exactly the Graphic Base Frequency and does it affect the gaming (throttling the GPU for example or wtv, my GPU is Radeon R9 270X.

Thanks in advance for any information.

it can damage if not done properly, blackout during the write, etc.
check your BIOS version, it just may be the right version already. version 3207. boot tino the BIOS and the version should be prominent.
if you do not have the proper BIOS version the CPU will not pass post and you cannot test the chip. the BIOS version must support the CPU First.

prime 95 is designed to stress the CPU.

the onboard GPU in the 2400 is running at 850 mhz. but if the load requires it can speed up to its max speed of 1.1Ghz

the GPU in the third generation chip, 3470, has a lower base clock but the same max speed of 1.1ghz.
the lower base frequency is to use less power, but when the need arises (gaming) it turns up the power and speed to max.

above only applicable if you are using the GPU built into the CPU. with a dedicated GPU the onboard has NOTHING to do with gaming performance.
simply the speeds above are moot to your situation as you have the 270x.

Your GPU is the R9 270x so the onboard chips you are asking about will be dark, not being used. at 0mhz.

@R_1
Thank you for this explanation. I wanted to make sure it wouldn't affect anything. I think in overall then, the i5 3470 would perfom better than the i5 2400. There will be no advantages from my actual i5 2400 vs the new i5 3470.

I hope my mobo P8P67 Pro (rev 3.1) will accept this cpu with no problem. Maybe at least just a bios update.

better performer yes. no advantage unless you count heat production. the motherboard supports all three i5 3470, regular, T, and S. but you are correct in that a BIOS update will be needed. Version 3207.

Then I am missing nothing after my research. Yes the 3470 is lower in TDP.

In any case, my mobo is limited to Ivey Bridge at max so if I want to make a little upgrade, the max I can get is even the 3570.

I will try to stress the new cpu for testing and hope everything will be fine.

Thank you again.

the motherboard support an i7 3770k on the same BIOS version as the i5 3470.
the i7 3770k would be the fastest the board will support.

That would be great if I find that CPU with a good price. I was refering to 3570 because I found someone selling it too. Maybe one last question please. If I have to test the 3470 on my mobo, do you think I must update the BIOS first before testing or I can test the CPU to see at least there are no problems and then once home I can update my BIOS? I am asking that because I heard that we shouldn't perform BIOS upgrade with no reason. It could damage things if not performed well !

And I think the best way to test a CPU is running a specific program and run a stress test.

Thank you.

Okay, the BIOS version is 1502. That's what msinfo32 shows me under BIOS version. There won't be any damage either if I update it and still use my actual 2400. I will just have to make sure of the CPU and update the BIOS when ready.

Thank you
