Need some mentoring on OC'ing my 1090T on a Asus Crosshair IV Formula board.

post #1 of 31
Thread Starter 
First, here's my CPU/MOBO/RAM/COOLER setup:

CPU: AMD Phenom II X6 1090T
MOBO: ASUS Crosshair IV Formula
RAM: Patriot G Series ‘Sector 5’ Edition 8GB DDR3 1333 (carry over, my mobo always defaults it to 1066)
Cooler: Thermalright Silver Arrow

I'm a first time Overclocker and I've read through most of the threads, including Owners (1090t & Crosshair IV F/E) regarding overclocking, but I'm having a bit of trouble understanding temperatures.

I find myself stopping Prime 95 a lot out of fear that my temps are getting too high (I feel I may be too cautious), but I really have no idea what the acceptable max is, as there seems to be a lot of different theories or responses to as what they are.

Some questions I have are:

1) What is the acceptable range for CPU temperature (ambient & max load)

2) What is the acceptable range for Core temperature (ambient & max load)

3) What is the acceptable range for NB temperature (ambient & max load)

Voltages seem like common knowledge after visiting a lot of the threads.

As it stands, I have every thing set to default after dabbling with it a bit last night.

I also have two 6970s in CF-mode atm, as I love to game, and I gather from threads that higher CPU-NB speeds coupled with a decent HT rate is a great way to improve performance.

Really, I'm just looking for helpful advice from someone who has experience with overclocking in general, perhaps with my hardware as well.

I want to get the most out of my system without compromising it's stability or straight up destroying it.

Any and all advice/input will be greatly appreciated.

1) Load temps are all that matter, most people here would agree to stay below 62C for best results.

2) Ignore core temps, they're not accurate until your cpu is heated up and by the time you get close to 60C they pretty much match the cpu temps.

3) No clue


You usually want to keep HT Link as close to 2000 as possible, overclocking it can cause instability and has been shown to offer little to no performance boost and can sometimes cause a performance loss.

62C was about the temperature my 1090t was reaching after 6 passes of 6 threaded blend.

Steady at around 61C, but is this temp realistic or just stress/torture? Should I be aiming lower with Prime95?

Voltage was 1.4 @ 4ghz.

What speeds are you running prime at? 61C seems quite a bit toastier than my results with my Cogage Arrow, I rarely broke 50 unless it was during the summer, and yours is the superior cooler.

Just stress/torture, what do you get with normal use?

What is your cpu clock at and what is your cpunb running at? How much voltage are you putting into them? Your temps seem a bit high considering thats a top of the line air cooler.

61C is fine on Prime so long as you don't usually do things with a lot of CPU usage for long periods of time, like folding.

Try to keep it under 55C while doing normal things (games), this will make it last longer and stay more stable

CPU-NB was set to around 2600. CPU-NB voltage was set around 1.2 & NB voltage was around 1.2 as well.

I realized later that it was a bad idea to try and OC both at the same time, but never stopped to think that this OC might be affecting my CPU temps as well.

Blonde moment? :x

That was another question I had... what order should I go in, is there a good order?...

Edit: Going to set every thing completely stock, will be back in a bit with normal results to compare.

At stock, under CPUID HW, CPU is showing 35C idle. Cores are showing up at 22C.

Why 2600? Most 1090T can go 3000+.

EDIT
Ok. Here the breakdown on that you need to know for ocing any athlon II and phenom II cpu on air.
1) Max cpu voltage is 1.55v.
2) Keep temp under 55c.
3) NB frequency take it as high as you can take it and stable.
4) CPU/NB voltage max 1.55v. This the voltage for NB Frequency.
5) Keep HT around 2000.
6) Keep memory close or under to stock speed.

I'm new to overclocking and just experimenting at the moment, which is why I started this thread.

I've seen a lot of users with posts of 3000+, but I'm in the dark and hesitant.
