Pssht why not mine kick around 1.6+ on air.
I am struggling to get my 945 over 3.4GHZ on my Crosshair III. Is this normal?
Whatever voltages as long as load temps are under 55 he is fine.
I'm a beginner in overclocking.
Here is my actual pc:
AMD Phenom II X4 965BE @3.8GHz (C3)
Cooler Master V8
G.Skill Ares DDR3 1600 PC3-12800 8GB 2x4GB CL9 (CAS 9-9-9-24)
Gigabyte GA-MA790FXT-UD5P rev1.0
Gigabyte GTX 460 OC 1GB
Cooler Master HAF XB
Windows 7 Ultimate.
I'm interested in reach 4.0GHz, and need advice.
In december the 20th there is a post in this thread:
This user has the same cpu, and I want to ask you if his setting are valid for my components.
I'm not at home now, this afternoon i'll try to test it.
Should be fine settings look about average for a C3 965BE.
Should be possible without much trouble. those are good chips
I'm not having any luck with my 965BE C3. I've got it running at 3600 with 18x stock voltages, but I can't get anywhere with increased voltage. When stress testing at settings above 18x or 200mhz bus it will either BSOD or the system simply powers off. I had hoped it would be as simple as set multi to 20x and raise cpu voltage to 1.45. I've read through various guides and it seems like nothing is working as expected. I don't think the system has time to overheat since it happens almost immediately when i start load testing with prime or occt. Anything I should be looking at?
I have no time to try the settings I said earlier, but now, my 965BE C3 is running a 19.5x multiplier and stock voltages.
That's 3900 MHz.
If I set the 20x in stock voltage, as i said before, it became unstable. That's why i'm interested in that guide.
In the BIOS I just disable the virtualization, Cool and Quiet and set the ram timings manually.
Could be that sirfa built powersupply you are running reaching its peak stable load. Unhappy voltages off the powersupply will cause what you described.
I hadn't considered that! I'll have to borrow a better power supply and see how it works out. Thanks!
Well, I tried another power supply and it didn't work any differently. System seems happy at 18.5 & 205 with all stock voltages though, so i think we'll leave it there.
your board is limited per chipset too.
BS mine was kicking 4.2ghz stable on 790FX...
CPUs have the play on it aswell, sometimes changing boards can get the chip to run farther. Realize overtime system components get old
I think that's probably the case with my system.
Had a bluescreen at 18.5 & 205, so now i'm back to 18 & 200.
Not an excuse more voltage fixes all problems.
@redstapler, What are you voltages at? I would suggest giving them a bump if they're still at stock
I've messed around with bumping voltages previously, 1.45 / 1.5 on the CPU and 1.15-1.30 on the CPUNB without any luck. That seems to add a lot of heat to the core temps though. I just did a run with OCCT at 18x with stock everything else and was seeing 58C peak. Perhaps my CPU cooler isn't up to the task?
For all of the chips In have dealt with keeping them under 50-55C is essential for 4ghz stability.
I would think your hyper 212 could manage better than that. Are the fans spinning up when it warms up? Could be thermal paste too. Or maybe I don't know how hot these can get
Yeah, me too. Fan is working correctly, I'm getting 100% fan speed from the CPU cooler under load. I've been wondering about thermal paste / mounting pressure. Using Ceramique 2 right now, mounting hardware is fully tightened.
4C cooler now:
Hi. Wassup? Dropped here & 1st thing i see someone have trouble with same CPU i have? I still run mine @ 4.0GHz.
Play with following:
VDDA voltage; (if you have this option)
HT/CPU-NB/NB/ voltages & frequencies;
Check my sys specs for CPU.
CM's V8 is good, but - what TIM you have?
By May this year it'll mark 2 years i run this CPU under same cooling @ 4.0GHz; impressive. If it'll run Carmageddon: Reincarnation @ max & won't break a sweat - call it incredible. Cheers all.
P.S. I'll drop here by tomorrow wachuwey, post me how high you upped the voltages/frequencies; leave HT freq @ 2000MHz.
Right now I'm using Artic Cooling MX-4. Put it about 5 or 6 months ago.
When you say "play" with voltages, you mean little increase and test, wright?
As I said before, I'm a beginner in overclocking.
P.S. I'm waiting the new Carmageddon:Reincarnation too.
I just set up the multiplier 200 x20 and Vcore to 1.440V (+0.025V)
About the ram, 800MHz, 9-9-9-24 default voltage.
It looks stable for the moment.
Run prime95 (27.9 build1) Blend test for 10 min and everything is ok. 9 tests passed , 0 errors 0 warning
Idle temp 36ºC (96ºF)
Load temp 54ºC (128ºF)
CPU fan at max rpm.
Tomorrow I'll run the test for a long time.
That all looks good. Nice volts and temps. I'm sure you already know but since you said you're a new overclocker I just wanna mention that the maximum safe voltage and temps for PhemonII is 1.55v CPU voltage and 62C.
