my cpu voltage

[a911master]

should I increase the cpu voltage when i oc

 

[Jonathan_King]

As a general rule, no. Gradually bring up the frequency, and run a torture test (Google Prime95). As soon as you fail a test, try bringing up the voltage slightly.

Be careful. I know someone who fried his CPU/MB increasing the voltage too much.

 

[a911master]

what is the max voltage intel I5 750 can take and the biostar tp55 mobo

 

[Jonathan_King]

I don't know. You can try Googling for that info.

I have a sneaking suspicion, though, that your BIOS won't even let you fry your CPU with too much voltage. I can only increase mine slightly, not nearly enough to cause damage.

 

[a911master]

thank you

 

[Jonathan_King]

No problem. Just remember that there is a certain risk to overclocking. It uses more juice, generates more heat, wears out quicker, and sadly, it doesn't usually affect performance very much. Usually the hard drive is the weakest link.

Not to sound rude or dis-respectful, but if you are asking this here, you should stop now and do a lot more research before you continue to any adjustments at all.

Some things you may want to look for/research;

Youll need to know the basics about your hardware:
CPUs Thermal limits, and MAX safe Vcore.
Where the Danger zone for voltage and temp. is.
Chipset thermal/voltage limits
RAM timings/voltage limits
Learn your bios. What the settings mean, the effect they have, and why to use them and when. Setting the wrong things incorrectly can easily end in disaster.

Youll also need a aftermarket cooling solution. OCing on stock cooling is asking for trouble.
Also, remeber, OC one thing at a time.
Just cranking up the CPU for the most part is bad, because when theres a instability, you will not know if its realted to a unstable CPU, RAM, or something else.

Dont let the board automatically adjust voltages either. Most tend to overvolt far too much.

He is asking because he is doing his research! He is doing the right thing. At least he did not say "I just fried my CPU because I OCed too hard. Is there any way to fix it?".

 

[Wishmaster]

Very true

And apologies if it sounded rude. I did not mean to be by my comments.
Only know the limits well before you start.

I really hate to see something bad happen because someone was simply unaware or Max safe limits

I dont take it as being rude you where just informing and yes i am resaerching this as i dont think i will need to oc if you look at the system specs a few poeple told me it will be hard to get it stable just trying to get some info and to learn. I am now seeing that i didnt know enough about computers and i just want to know more. I have some bugs to fix with my system it just dosent seem fast enough the last set up was faster with less and no oc (intel 5200 core 2 duo 2.53ghz with 4gigs of ram) the only reason i built this system was my old mobo would only take 4 gigs of ram. in your guys opinion is my set up good veiw the specs

 

[Wishmaster]

From your specs that looks like a good build IMO.
Also, remember Win7 will speed up over a couple days as it "tweaks" itself. the first couple days it will still be indexing and building pre-fetch etc.
Give it a couple days to learn your habits
Defragging may help a bit as well, after you get everything set up.


Some things Ive learned, if it helps:

Overclocking may help slightly with overall system performance.
However, the most noticable gains will be in any app that relies heavily on CPU calculations. HD Video encoding for example will benefit greatly from a OC'd CPU (provided your stable) or any other app that does intense calculations. As CPU speed means everything here.

On the whole, it wont make a 'Huge" difference.

The best upgrade you can do (for overall system performance)in daily use, is moving to a SSD (at least for the OS), as HD's are the largest bottleneck in any system.


Don't get me wrong, Overclocking can help slightly (depending what you do mostly), and is fun escpecially for those who just enjoy it or make a hobby of it.

But the simple fact is, system performance as a whole wont benefit greatly.
As I stated previously, HD bottlenecks is the major performance factor of any system, and no amount of CPU/RAM speed can overcome that.

Just keep this in mind.
If you want to learn to OC, do some research and have patience because it will take a lot of both. just be careful and have fun with it!!

My 2C for what its worth. Perhaps others have a different opinion, but this is my take on it.

You will indeed need to adjust the CPU voltage but also CPU VTT and other voltage adjustments will be required. You will want to keep those voltages as low as possible but still remain completely stable. Heat can easily be the limiting factore when overclocking but there are plenty of ways around that. I like Prime Blend test for stablity testing. There are plenty of overclocking guides for the i7 and they aren't nearly as difficult to overclock as a core2 quad.

The difference between my default 3.0GHz CPU and 800Mhz memory compared to 4.05GHz and 1200Mhz memory speed is night and day, no comparison at all IMO. Everything from opening web pages to programs and also gaming frame rates are much much faster. No comparison to default clocks at all in my opinion. I have overclocked three different CPU's on this board, the overclocked quad core works the best for me but my E8600 at 4.5GHz was pretty decent also. By the way Wishmaster, you can easily get more from your Q9650 if you so desire, they really come alive at 4.05GHz.

As for the HDD being the bottle neck, true for certain tasks such as loading programs or games but it doesn't matter for other operations such as gaming frame rates which is what matters most to those of us who overclock. Of course for slow HDD's you only need to purchase a SSD or two to fix that problem.

I would say. depends up on how high you OC it.

0.2~0.6GHz OC should be ok with no voltage lvl up.

Thats my idea

 

[a911master]

Thank you guys for the info but i cant get this machine stable when i put more then 2 gigs of ram ocz keeps sying they are matched if i lossen the timmings for the ram should that help i ran memtest 86+ on each stick and i got diffrent speeds was the same when i used the winast mem from the command promt any ideas about how to fix this
