Hey guys! Ello it's moi again, I ran IntelburnTest with my new Corsair Dominator PC2-8500 overclocked to 1137MHz temp is cool to warm (Touching). Okay well IntelBurnTest is telling me that I fail the stability TEST, is it important to have it 110% stable? I personaly havent had any problem while playing games or doing what I do. Is there anyway to fix the Residual so its all the same?
Well aslong as you don't have any problem with it you can have it unstable as you like. Obviously if it suddenly does crash when you don't want ti to you can't complain but otherwise not really a problem.
Many people see to call it stable enough after 12 or so hours of orthos or super pi. If it suits you, then it shouldn't be a problem.
The fact that it's not stable means your processor is being pushed too hard. You CAN keep it that way if it works okay for you, but your processor WILL experience a very short lifespan. It comes down to whether a few MHz is worth the cost of a new processor in the long run.
as long as there is not that much voltage being pushed to the processor I dont think that it would cause a major difference in the lifespan of the processor, but thats just me. The instability could be the processor/ mobo or the ram.
Okay guys, I got a major headache trying to figure this out and sadly failed. How do I go about making my ram ratio 1:1 and not 3:4? CPU-Z RAM I bought the Corsair PC2-8500 1066MHz 2x 2GB but my computer sees it as PC2-6400 800MHz so I try and overclock it to 1066 but the ratio isn't 1:1 and I think that's the reason why my computer is unstable?
i personally HAVE to get it pass Intel Burn test with stable results, otherwise i will not be satisfied. but if you are not using your PC to do important work such as projects or homework, you may not care about 110% stibility.
DorkSterr, based on the CPU-Z stats posted, you're running a 400MHz FSB, correct? The reason you've got a 3:4 RAM divider, is because the RAM is 1066MHz ram (which equates out to 533MHz one way). Your RAM is indeed running at it's rated speed, but if you want to drop the divider down to 1:1, you will be running at 800MHz (which equates to 400MHz or 1:1 with the FSB). Honestly that's probably not the reason your computer is unstable... You can try setting the divider on the memory, and see what results you get, but it's probably your CPU.
But then wouldn't I be under clocking my ram? And for the CPU I am starting to think its not ram related that my computer is unstable too, based on Prime95 when ever I start prime one core will fail or stop the second I run prime, there for I would pull out a hand full of hair and restart the computer entering BIOS and raising the CPU voltages hence Prime lasts longer without cores failing (as fast) I've been repeating this for the last 4-5 hours now... 1 Volt at a time....
You WOULD be underclocking your RAM, but honestly most 1066MHz rated RAM kits are just overclocked 800MHz kits. Plus, the actual performance difference is negligible. I prefer to run my RAM synchronous with the FSB as well because there's a latency penalty for running anything other than 1:1, but the extra speed when higher clocked usually makes up for it (which goes back to my earlier statement of the difference being negligible). Plus, since you're underclocking your RAM, you can also tighten the timings up to make the RAM perform better, which will often give you BETTER performance than running the RAM at the higher speed.
Ah, just noticed that as well... I believe the 65nm chips you need to keep under 1.6v on air cooling (even with a TRUE). Edit: If your failing Prime95 immediately, you're way too high on speed, or way too low on voltage.
Okay F*%# it! This is to much I'm already at 1.45V and still the F&%#ing cores fail! Sorry for my bad language but this is really getting to me, I've been doing this for well over 5hours and probably restarted well over 80times. What do you guys recommend I do? Ask me to print screen any info for you guys to see I'll do anything to get this stable, I really need help on this. Thanks so much
If you want my advice, start over from scratch. Drop the speed and voltages back to stock, then work your way up from there. Set the RAM at a 1:1 divider, and increase the FSB on the CPU by 10MHz using stock voltages until Prime95 fails in under 10 minutes. Once Prime95 fails, drop the FSB 2-3MHz at a time until Prime95 runs for over 10 minutes. Increase the voltage one notch in your BIOS, and move up 1-2MHz on the FSB until Prime95 fails in under 10 minutes. Repeat the process until you: 1. Reach the maxiumum voltage recommended for air cooling on a Q6600. 2. Reach the maximum temperature recommended for a Q6600. If you reach one of the above, drop the FSB down to the last working setup UNDER the required specs above. From there, your best bet is dropping the FSB about 5MHz, and running IntelBurnTest for somewhere between 5 and 15 cycles (the more the better). That's pretty much it in a nutshell. After you get the CPU where you can, then you can turn to the memory. I CANNOT stress enough though, YOU CAN'T RUSH THE PROCESS! If you're really wanting to get a good overclock, it WILL take a LOT of time. If you're not willing to put the time in, you're better off leaving your setup at stock speeds.
Okay I have one more question, which is a faster, better over all noticeable preference increase, a memory that is at PC2-8500 1137Mhz 5-5-5-15 Or PC2 8500 under clocked to 753MHz 4-4-4-12
I don't know the full answer to that to be honest... Based on the numbers they should be pretty much dead even though (assuming the 753MHz is 1:1 with the FSB).
Okay so this is what I did I got my CPU & RAM stable enough for me to run Prime for 1H with max temp of 70 and finish IntelBurnTest (10 Runs) Im happy, now since My Corsair PC2-8500 isnt showing up as 1066MHz but showing as 800MHz I decided to add my older OCZ PC2-6400 and mixed them which makes a total of 8GB of ram at PC2-6400 753MHz 4-4-4-12 (A waste of $133 for the Corsairs but O' well). So did I make a good decision or should I take out the OCZ and keep the 4GB Corsair and OC it to 1137 @ 5-5-5-15?
Nice to see some equal numbers there! I'm assuming based on the RAM speed and signature that you're running at 3.4GHz (753 /2 = 377 * 9 = ~3400) ? As for the RAM, you can try looking for a guide to adjusting timings on DDR2 RAM (which I'm currently looking for a good one myself), and tweak the timings on the Corsair to get better performance than the OCZ is capable of. Based on the speed you're running, and the quality of the RAM, you should be able to get MUCH better timings than 4-4-4-12. I only have mine at 4-4-4-12 because I KNOW it's stable at this speed. Once I find a good guide, it'll be tweaked as well.
Yup Im running my CPU at 9 X 378 with my RAM sadly underclock but 4-4-4-12 whats a faster timing? 3-3-3-11? I was going to try that lol.
