My CPU performance
    #14658892 - 06/23/11 11:07 AM (12 years, 10 months ago)

I got i7 at factory 3.07 Ghz

I been running it at 3.3gh OC for half a year

Just now i run a test - noticed how long it takes for windows to load from my 2 raid 0 drives.

These are the timings:


3.3ghz = 25 seconds

3.7 Ghz =20 seconds

3.07 Ghz .............................................. 22 seconds!!!  :eek: :eek: :eek:

Interesting innit?

And oohh yeah, i used one of those expensive 3rd party coolers with the CPU to keep it cool with 3.33ghz

But now that i dont need it, fact is it runs faster on factory setting at 3.0ghz so im going to install a cooler that came with the processor.

BTW the cooler that came with the CPU clicks in into mother board, to remove it, just push the legs in and it comes out.

With my 3rd party cooler, althought it supposed to give better performance it is a pain in the butt to install it - need screw driver and have to remove mother board to screw it into place :shrug:

Were you expecting an overclocked CPU to give you better boot times?  I think that performance aspect is more tied to your hard disk and memory.  Overclocking your CPU will help with tasks like encoding video and unzipping archives.

i dont agree


if booting times wasnt down to CPU then all 3 experiments would fetch same result


But as u can see there differ according to clock speed ! :shrug:

Looks like a negligible difference to me.  Especially since there is no trend, its probably within the error bars.  Are those numbers averages or just one data point?

I think i can explain this variation




First of all, when i overclocked it to 3.3 Ghz it did improve performance a bit, but it also didnt fit in with FSB, chipset and north bridge, 3.33 ghz does not work harmoneosly wit those devies apparently.

So 3.07 ghz is a native speed and evrything is smooth :shrug:

Disable all your startup programs in msconfig. Startup times can be effected by a bunch of variables. But usually software/HD performance/OS integrity.
And yeah OCing the CPU isn't going to give you much if any better startup times. The board is probably only using 1 core on the CPU to POST anyway.
And those data points are irrelevant, unless they were stress tested stable OCs?
Startup is 95% HDD. CPU and memory aren't even really pushed until windows loads. Not to say that OCs can't help.. they just aren't the main factor. Also just because you achieve a certain OC does not mean it is a stable OC, there are other variables you could miss having Turbo Mode enabled which could increase boot times. highers clock speeds can potentially increase boot times by a little bit. But there's a hundred+ different variables at play here and any one of them could change something but it's all going to be very negligible.
You want faster startup times, disable all startup programs/run diskchecks/defrag/minimal services/virus checks/regular maintenance/flash latest MB bios/clean install windows etc.
You want insane boot times, get an SSD.

Did you allow the system to return to ambient temperature before each boot and average multiple times for each clock speed? How did you negate the other variables?

Well, he's refused to answer any questions about how those figures were determined and what they represent, so it doesn't seem likely to me that he considered other variables.

Having figures without a clear understanding of what they represent or how they were derived is not helpful, obviously, but that's all that's been provided.

It's a bit odd that OC'ing your CPU had such an effect on your boot times.  Are you using a secondary SATA controller?  If you have an i7 and are using your primary controller... normally the Intel controller, then your boot time will be dependent on your HDD read speeds.  It sounds like you have a bottleneck because you may be using something other than the primary controller.  I have an OCZ Vertex 2 on my Sabertooth x58 and I originally had it on my Marvell SATA III controller since there used to be a problem with the SSD being recognized from a cold boot.  That has been fixed since putting the SSD on a power cable by itself (modular PSU) and/or a BIOS firmware upgrade... idk since I did both when wiping all my drives.  Since putting the SSD on port 1 of my Intel controller and disabling the Marvell controller completely, my boot time improved to under 10 seconds and about 15 with all the BIOS POST shit because I let me ethernet ROM load.  Going from stock settings with an i7-950 to OC'ing it to ~4 GHz did nothing to improve that.

Its got nothing to do with any controllers

And when u boot windows notice hard drive activity - it is on 50% and off 50%! so it means the lag is when CPU loads stuff :shrug:

1. It's got everything to do with controllers. HDD read/write speed effects your boot times more than anything
Also the drive 50% on and 50% off, what kind of objective measure is that? They could just be pausing to read. Isn't it RAID0? What drives? On what controller?
while an OC CAN potentially help your boot times by a second or two, an unstable OC could make it even worse. Your increased boot times could be due to a single BIOS setting being off. Just because you get the CPU to a certain clock doesn't mean it's 100% stable. And even then it's not that big of a factor in boot times. Do you have Fast Boot disabled? Have you disabled all unnecessary peripherals? Are you using Turbo Mode? Are you using the exact same settings on every OC? Like I said there's a hundred different variables.
Don't believe me>?

Have you tried any of those things in the first thread? Have you run disk checks? Defrags? Updated all your drivers and firmware? Disabled startup items? When's the last time you reinstalled Windows?

Desant can't have that old of a motherboard to have an i7, even newer if Sandy Bridge, so assuming he has two WD Raptors (10,000rpm) in RAID 0 and on his Intel controller, his boot times are due to fucked up BIOS settings like you said Shroomism.  There really isn't any other way to account for it, especially since you can look at virtually any hardware website/forum and see endless benchmarks of any SSD (not in RAID) vs RAID 0 Raptors which is usually the only HDD even shown, and the raptors get killed every single time.

Also, how would a CPU OC have anything to do with your boot time if say... you have an IBIS and load Win 7 Ultimate in 4 seconds?  It doesn't.
