I'm trying to get my 1090T at 4.0GHz, first time overclocking, need some help!

Hi guys,

I'm using OCCT for Stress testing. As I type this my PC is running fine at 4.0GHz for web browsing but cannot get it to test a 1hr Auto Medium Data Normal test in OCCT. It fails about 5 mins in everytime.

I am using a Coolit Eco Watercooler for my CPU. It idles around 28-32 and under load it gets around 38-43 degrees. I also have 2 x 240mm case fans and 3 x 120 mm case fans running in a AZZA 1000 case.


My latest attempt I had my Vcore set in bios at 1.45, CPU Multi at 20x, Ram at 1.5v.

When I took NB off auto and set at 200 MHz, and HT off Auto and set at 2000 MHz, I cant even boot into Windows.

What am I doing wrong?

My ram is Corsair XMS3 DDR3 2 x 4GB Kit.

I have a stable 3.8GHz o/c, thought I'd mention that.

I'm learning and getting addicted. Been building PC's for 15 yrs and have always gone stock, so never had any need to learn about oc stuff.

Back when I was OCing my C2 stepping Phenom II X4, I left everything on auto except for CPU-NB, CPU VCore, and the multipliers for the NB/HT. I didn't have a black edition, but it sounds like you do. Just wondering, on the "auto" settings what NB Freq/HT is it running at? You should keep HT close to stock, which may or may not be 1800 or 2000, and as for NB, you can raise that up a bit but you'll need to raise CPU-NB voltage, (not NB Voltage. That's a different option). Also, you still have some voltage left in the chip. AMD specs say that 1.5V is the safe limit....
 
Sorry have 3.8 stable at 1.385 not 1.4


AMD spec sheet has 1.4 as being max, is it safe to go over this for a machine that's runs 24/7 most of the time?


EDIT: I typed this on a cell phone and it auto corrected some stuff wrong!

my x6 is at 1.47 under and H50 and stays under 53c. I think max volt/max temp is 1.5/55c
Google it or if someone else can comment to make sure, but I have not had any problems and have been at these settings for months.

Yeah I remember someone talking about AMD Thubans OCing themselves and going up to 1.475V...
 
At 3.8GHz with my Coolit Eco Watercooling my CPU temp maxes out at 46 during OCCT stress testing with CPU at 1.3875

With regular use I never see it over 36 and at idle is sits around 29. (CPU, not core, core temps idle around 19-20)

Since the AMD Spec sheet says 1.4v, I am a little hesitant to go over. I am just wondering if there is anything I'm not doing right. I really am just playing with the vcore and the multiplier with the ram and HT set to default. (1.5v and 2000MHz)

Well, raise it to 1.4V. If you can't get it, well...there's not much we can say other than raise the voltage or be happy with what you've achieved so far. Also, going over that safe limit by a little won't be a really big deal, as CPU chips last forever anyways...but its up to you

I've done some research and am stress testing now.

I find if there is an error, OCCT will find within a hour. (If it passes an hour then Ill run it all night to be sure)

A lot of people going as high as 1.5.

I am going to get to 4.0. Doing research. Will update here!

Yeah a lot of people go 1.5V....I mean, it uses the same 45nm process as the other Phenom IIs so I don't see why it would change from 1.5 to 1.4V because of more cores.....your cooling is very adequate and I don't think you need to worry about electromigration much.
 
Well I went to bed last night and set OCCT (Medium, Normal) to run for 4 hours.

At 1.465 it failed at 3 hours 40 mins.

I just bumped it up to 1.475 and am attempting 4 hours again.

In the last 2 weeks of messing around with my O/Cing, I have found OCCT to find errors much much faster than prime 95. If it passes OCCT for 4 hours, then I'll run prime95 all night after to be sure.


Am I stress testing too long? Besides a few hours of gaming a week, the PC is mostly used for web browsing. Is it stable enough? Or should I give 1.475 a go first like Im doing now?

Also I have cool and quiet disabled, but Ive read a few peoples comments that since I am only changing the multi, that Cool and Quiet could still be ok? Or should I keep disabled?
 
Well got it to pass 4 hours of OCCT at 1.475 vcore, but am experiencing some big Vdroops with my M4N98TD Evo motherboard running newest bios. Under load Its running around 1.38v, and when idle Im not that stable.

I'm just going to end it here and go with my 3.8GHz stable O/C. The performance gain of 200MHz isn't worth anymore of my time, and I won't notice it, and I have more peace of mind knowing I can do this O/C within AMD's specs. (stable at 1.385 vcore)

Thanks for everyones help!

Pretty good OC for being under 1.4v, congrats.

Yeah I find it so odd how I can pass any stress test I throw at my chip with 1.385v at 3.8GHz, but am needing to go as high as 1.45+ to get OCCT to run a full 4 hours at 4.0GHz.

I'm happy with 3.8, its idling around 29 degrees and at 100% load hitting low 40's. 200MHz isn't going to be noticeable anyways, and not worth the extra voltage IMO.

What you are doing wrong is aiming for a certain number. Overclocking is a journey, not a destination.

Classic signs of something (likely CPU) hitting limits, because it will suddenly need a lot more voltage to get a bit higher.

Well I just wanted to be part of the 4.0GHz club but its not that important 🙂

This won't solve your problem, but I have a similar experience and so I am also not part of the "4GHz" club.

At stock vcore, my C3 Phenom II X4 965 BE can do 3.7GHz core (along with 2.6GHz CPU-NB overclock, for only a minor increase in CPU-NB voltage). No sweat. In fact, I can lower the vcore to 1.35V AND overclock to 3.6GHz with no problem.

But it is not possible to do 4GHz even with 1.5V.

However, I can do 4GHz if I disable two cores (effectively making the chip only a dual core), and settling on 1.45 vcore. At this same setting, without disabling cores, I can only do 3.813 GHz.

That is the story of how I ended up not joining the 4GHz club.

It is what it is: each chip is unique, so there is no guaranteed overclock, and I happened to get one that is worse than what most reviewers seemed to have gotten.
 
maybe the limit of 1.4V is because it'd get hotter faster as it has slightly less room per core on the die?

ps. I'm just dabbling in OC'ing myself, so i'm not sure at all about what i say, just making an educated guess.
