I have vista 64 bit is this update for me or just a mobo brand

Well typicaly you press the delete key at post to enter your BIOS. From there you can change your FSB, CPU Multi, etc.

Your CPU frequency is calculated by multiplying your CPU Multi x FSB = CPU frequency

ex. 200FSB x 12.5 Multi = 2500Mhz

Just increase the FSB by 10 or the Multi by .5 and you get an OC

ex 210FSB x 12.5 = 2625 Mhz

For a more elaborate guide just go here http://forums.techpowerup.com/showthread.php?t=58746&page=90 and look at post 2244

OK thanks but do i need to up the voltage for the rams? whats the most stable speed available for air cooling?

Well it depends on how well your air cooling is. You might need to up the Volts of the RAM if you get them to high and you will know they are to high when applications start crashing and such.

For now don't worry about the RAM. Just try to get the CPU OC a bit. Just increase the Multi of your CPU and if it crashes raise the volts .1. I recommend you get an app to monitor temps of your CPU. For instance I use AMD Overdrive for that.

I agree with just using the multi. For first time o/c'ers its the best way to go.

Also, Core Temp is great and runs quietly in the background

the auto clock profile thing in the bios is good to gauge where to start from for fsb oc'ing

Wondering if anyone can give me some pointers on which way to orient the fans that are in my case. I'm not sure which should be exhaust and which should be intake. In addition to the fans you see (shown by yellow arrows) there is one that goes on the other side of the case too

 

[Moose]

Have the front ones as intake and the rear as exhaust, to creat an air flow through the case, and the top one as exhaust as hot air rises, (unless that arrow points at the PSU).

This makes sense to me. There is a fan on the top for exhaust. Should I make the one on the side panel (that is currently not in the picture) an intake or exhaust?

Thank you for the help

Also: Has anyone ever had dealings with Portatech a.k.a PC Boost a.k.a SMK Superstore before?
I'm finding my current experience to be pretty terrible and I'm not sure if its a normal occurrence for them or if I'm just getting unlucky.

 

[Moose]

I would say intake unless you want a gush of hot air going across your face lol

 

[erb]

The computer is a few feet off to my left. It rests on a small shelf at the bottom of the desk. The fan it self would be pointing way away from me anyhow. Was just trying to figure out the best possible air flow scenario. My computer is in the basement as well so that is another thing that works in my favor. Its a good 10 degrees F cooler here than it is on the other floors

My computer keeps my room warm , still have the fan as intake as it creates a nice jet against your cpu.

That is a good idea. Just got my core contact freezer too, that should help

never tried it bro

exactly what moose said

looks good bro, when you putting it on?

Soon as portatech.com ships me the correct motherboard. They sent me a 95w ECS board when I ordered the Phenom and charged me $15 to "setup and test cpu". Needless to say a 140w processor didn't work on the board so I had to RMA it and now they've had it back since Friday but still haven't shipped out my new stuff

yeah what moose said.

heat rises...no need to fight physics....top should exhaust

Thanks for the cooling tips. Did some minor modification on the front of the case too.

be careful, case modding is addictive hehehehe.

Hello i have an asus m3a79-t deluxe, 9950 140w phenom, antec 1200 case, cpu on stock, ocz titanuim-6400 4-4-4 ram that i want to ran at 1066 at around 5-5-5-15 2.1 however i cant get a decent speed stable overclock could anyone give me details on reaching 3.1-3.2 stable with everything to set as in SB, processor volts, processor-nb volts, nb ht volt, nb core volt, ram volt/timings if that will help, processor frequency multiplier, processor-nb frequency multiplier, cpu-nb ht link speed, acc?, cpu vdda?, and anything else ive tried so many combinations based on information from the internet from other overclocks but never overclocked stable with prime95 tests can someone please help

Hello there yvanm,

Welcome to TPU,

First off what you want to do is set things like this.


FSB 200
processor frequency multiplier x12
HT link speed 2.0 GHz
CPU voltage set it at 1.3125v
Processor CPU voltage 1.32v


the rest you can leave on auto except the vdda, which is to be set at 2.6v.


To clock just for now so you get the feel of it, use the CPU multiplier. These chips come with a multiplier of 13 out of the box, increase it in the smallest increments possible, (think it is .5). then if not stable raise one notch on the CPU voltage at a time. Give that a shot and let us know how it went.


Oh and also the "DDR Voltage", thats your RAM voltage, set it to what specs reccommend.

 

[yvanm]

wow very fast reply ill try those now thank you very much which stability program do you recommed and in my power setting it has smart q-fan function and cpu fan warning speed are these needed? oh and for CPU voltage set it at 1.3125v
Processor CPU voltage 1.32v
which one is suppost to be processor-nb ?

also when incresing voltage do i increase both cpu-nb and cpu or just the cpu volts?

 

[yvanm]

hmmm is this normal for some reason when clocked at 2707 my cpu temperature is in the 60's... when running prime 95 that is

 

[erb]

Is there a difference in the overclockability of a 140w 9950 compared to the 95w version?
I canceled my order with Portatech and was about to order from Newegg but they have the 140w and 95w version, so I don't know which one would be better to get

Another thing: Now I have more options for choice of motherboard. Initially I was going to get the Asrock AOD790GX however, if there is something better (hoping to stay with a 790 chipset board) please let me know your opinions (I'll never need to use one of those 4x pci-e 16 slot monsters.)
