The Ultimate CPU Overclocking Guide!
A requested video. Part 2 of 2. Intel Core i7 overclock comparison (3,8GHz – 4GHZ – 4,2GHz) with Crysis Benchmarking Tool. Using ATi Radeon HD 4870 X2 @ default clocks, 6GBs of Corsair XMS3 and Asus P6T X58 motherboard.

@ProjectRealityBf2 – It will, not too much though…
@arvutihull I’m running a GTX 470 right now with no issues and I doubt if I add a second one there is going to be no bottleneck with this kind of overclock.
@ProjectRealityBf2 – All depends on what graphics setup you’re using.
@arvutihull so not even worth running it at 4.2 ghz at those voltages 24/7, I run my i7-875K @ 3.9 ghz 1.3v 24/7 and find that overclocking anything over 3.9 gives almost no performance improvements!
@arvutihull that why i say for me not the same depends on the rig
@colonybikes1 – Yes, everything depends on the graphics card. With high-end graphics card there is bigger difference, with mid-end graphics card very slight difference and with low-end graphics card no difference at all.
for me when i OC 4.0Ghz with my core i5 750 i got no improvement on FPS.
@winkipinky – Check my channel’s FAQ in my channel description for an answer.
WTF is that terrible sound on your video…….?!
3,8GHz VS. 4,2GHz with 5970 about 5FPS difference.
i know about 5970, right now the only reason for this card is huge resolution, so how much additional fps do you have with 4.2Ghz?
4870 X2 isn’t really a weak graphics card. I have a 5970 now and must say that the upgrade really wasn’t worth it, 5970 isn’t much faster in games, with current drivers at least.
what the reason for this comparison, you weak point is graphic, with two 5870 or 5970 test will be much interesting and useful
True. In my latest benchmarking videos I’m moving task manager on my desktop so it jumps to 4200MHz for a second.
it you take 200mhz bus x 12 multiplier you get only 2.4ghz .. its says nothing about any 4.2 ghz.. i dont say that i dont belive you i only say that you show dont conferm that you runs on 4.2ghz
200 bus speed shows it. Also the idle temps and performance difference between 3,8GHz and 4,2GHz shows it.
okey! Well shouldnt you show the viewers that its clocked to 4.2ghz that it is what it is?
It is 4,2GHz, CPU downclocks itself when on idle (with power saving enabled).
hey .. the cpu is not 4.2 ghz its 2.4ghz.. !!
If you have just one client it will use one core.
i ahve a quad core can i use more than one client to utilize all my cores or does it do that anyways
I have so many to get more points out of my CPU. They’re regular clients so they’re easy to set up and pause when necessary.
i see you have folding at home clients in the corner why do you have so many?
@yespleasefen
The price you pay for good overclocks.
Difference between silent and loud for my Q6600 is 3.2ghz and 3.8ghz. I choose loud and headphones
Turn down your speakers, there’s nothing to listen in this video.
