1045t OC troubles

post #1 of 5
Thread Starter 
I got the 1045t for really cheap and this is my first OC with a chip that is not unlocked aka FX or intel k.

I have read that this chip does well with increasing the bus and keeps good temps.

I do a lot of video photo editing work and a super cheap processor with six cores is more than adequate for me currently. 3.8 would be nice though maybe a 3.7 stable 24/7 OC would be good too.

I have been able to accomplish a 3.8 ghz OC and it will post and load windows, however if I try to run any sort of stress test like prime 95 or geekbench 2 etc...it blue screens.

Here are my numbers.

AMD Phenom II X6 1045T
Windows 7 Home Premium Edition 64-bit SP1

Slot 4 Manufacturer : Kingston
The latest version of BIOS whatever that is....

Voltage is set at auto. It idles at 1.404 and under full load it ramps up to 1.456 max.
NB is set at 2450mhz or something close to that and HT link is 1980mhz

I also set NB frequency to be the same at HT link and it still memory dumped. Because it blue screens and memory dumps is my memory the reason I can maintain a stable 3.8 or higher or is it the chip????

I would appreciate any advice on how I can specifically achieve a stable 3.8 or better OC.

Cheers

Generally it is most likely the memory.
Let me start off by saying that filling up your computer specs from the profile page would help us help you thumb.gif
First, I would suggest not using the automatic CPU voltage regulation. You can experiment a bit to find out how much juice your CPU requires.
Regarding the memory - what speed is it rated at? Perhaps try loosening up the primary timings and notching up the voltage a little bit.
Also, please provide the error code from the BSOD because it most likely points the culprit out.

Generally, for a stable FSB overclock there are a couple of steps that you might want to stick by:
A tip (Click to show)
I recommend setting up a spreadsheet in which you can keep track of your frequencies/multipliers/temps/stability - you may refer to it in the process of overclocking, or in the future. Trust me, it helps. thumb.gif

1. Find out the maximum frequency of your components
1.1. Max FSB - drop CPU ratio from 13.5 to the lowest possible. (you can set it all the way down to 4 IIRC); drop memory ratio as much as possible. Start increasing the FSB step by step (step=5MHz just so you can save some time), add CPU-NB Voltage (often referred to as VDD) when necessary. Generally, you don't wanna really go over 1.3V there. Boot, stress test for 5-ish minutes. Rinse and repeat until two incremental steps do not help stability. Fall back 2-3MHz and retest. If you crash, fall back once more until you reach stable. Set back CPU-NB V if necessary.
*Keep HT link roughly about 2000MHz by adjusting it's multiplier - in the most cases it allows for/improves system stability.

1.2. Max CPU frequency - leave RAM at lowest ratio. Fall back to default FSB frequency/current. Set the CPU multiplier at 13.5. Start notching FSB up and stress test until you crash. Add VCore/CPU-NB V as needed. Keep going until you crash and two incremental steps of Vcore do not help or you reach the temperature threshold.

1.3. Max memory frequency - fall back to default FSB, drop CPU multi to 4. Start increasing FSB and stress test until you crash. Add voltage to the RAM as necessary. Max Vram is determined by your memory specs. Now, here is the trick. If you get consistent instability and your FSB is far from the max CPU FSB, lower the RAM:CPU ratio. Proceed with overclocking the FSB. Repeat until system instability or you reach the maximum FSB your CPU can run on. Minor timings adjustment often comes in handy - loosening them will improve stability and yet generally the higher clock speed will provide more benefit.

N.B. Be wary with temperatures not only on the CPU, but also the northbridge! If you don't have a temp gun or another reliable thermometer at your disposal, you can use the fingertip method. Just make sure to add a layer of non-conductor (like a latex glove) between your skin and the heatspreader (I suppose) you are touching. Just to be on the safe side.

After you've established all three maximum frequencies (don't forget temps!), it's a matter of balance and whatever you see fit for your use to finalize your overclock and run a looong stability torture test.

Welcome to OCN and good luck thumb.gif

FSB OC Results.xlsx 11k .xlsx file

Thank you for a thorough response. I have been working on the 1.1 portion and attached are the results. A FSB of 285 is the only frequency I could get stable. Anything above that and it did not seem to matter what I did to the CPU-NB Voltage. I did try 286-290 all at 1.2V-1.3V and I always got the same errors, which if my research is correct is memory related?????

I will work on the cpu frequency and memory OC later.

p.s. I am using a...
asus m5a99x evo rev.2.0
CM hyper 212+ push and pull 2000RPM
16GB Kingston HyperX blu rated to 1600mhz 9-9-9-24 CAS
thermaltake V4 BE with 2 case fans running CM 3000RPM 120mm fans in/out
Gigabyte Geforce GTX 650ti boost 1125/1500 2GB windforce 2x

Again thanks for the response.

I managed to get a "stable" OC at 3.8ghz.

I ran prime 95 for 2 hours but then noticed that it was running a maximum cpu temp of 67C. The mainboard temp was 32C. So while it is generally a "stable overclock" It is too hot to really stress test to make out a real stable state.

CPU: 3795
VCore: 1.5V only voltage that kept it stable
FSB: 280
Multiplier: 13.5
HT link: 1967
NB Freq: 1967
CPU-NB V: 1.150
Mem: 562mhz, 1:2, 6-6-6-18-20-1T

Very well, so now you know your maximum FSB. And so far it's looking good. thumb.gif
For the reference, on my old ASUS M3A78 motherboard with a Athlon II X4 620 in it, I was able to stabilize a 277MHz FSB, the motherboard would give up on any more. So that's a good FSB.

The 0x0A means RAM indeed, however I have a feeling since you're running it downclocked (~1064MHz) that the culprit is the NB. Especially since CPU multiplier is set to 4x .

I'd suggest moving on to step two: max CPU frequency.
After you've established a baseline overclock (memory too), then you can start toying around with the finer details. Some combinations may work better than others.

No problem, I am so nostalgic about FSB overclocks... Ahhh, good times. rolleyes.gif
