1090t problems - Page 3

post #21 of 38
@ jprovido, I definitely don't think its the RAM voltage because he set it to 1.65v or 1.68v, so its got enough power. BUT it could be the RAM, see below post.

The temps shoot up right away to 66c and hover there only cuz the processor is backing itself down to protect itself I think. Someone pleasse help me figure out these temps!!

The only time my temps shot way up excessively and fast was during my h70 install (another reason I'm going switch out my H70 for the Silver Arrow) where obviously I did not have the pump on the CPU chip tight enough! Thus, here I would try to make sure you've installed your air cooler correctly and applied the TIM correctly.

Remember to always turn off "coreboost, turboboost, core/turbo unlocker, etc" and also turn off Cool'n'Quiet, C1E, etc when your trying to overclock your system. These can produce inconsistent variables when your running tests. For example, with Cool'n'Quiet my multiplier would randomly change from 16 to all the way down to 4 making it only 1.0 Ghz.

Overclock your comp and get it stable first to where you want, then start to play with those features. If you can make it work with them then you could prolong the life of your CPU.

Should I try to switch to the heatsink that came with the processor and see if maybe its my cooler?

I'm not familiar with your exact RAM, but I did a little research and It appears that 1.65v is the MAX or max safe voltage, so I wouldn't go over that. Here is a review that I found;

"The DDR3-1333MHz with CL9 at 1.65V rating was fully confirmed in our brief tests, although we managed to push overclocking even higher and up to 1453MHz for 1.50V and ~1504MHz at 1.65V. However, a nice stable DDR3-1333MHz with CL9 and 1.50V setting will be energy saving and will extend the lifetime of the memory"

Now in the early stages of overclocking your simply trying to find the max overclock of the CPU and basically taking the RAM out of the equation. IE, set the RAM speed a lot lower such as 800 or 900 MHz, raise up the timings such as 11-11-11-30-?T, and raise the voltage such as 1.6v. This way, you can eliminate the RAM from the instability problem. Still having problems? Run memtest to ensure your RAM is not bad. If you get any errors, run memtest with each individual stick to see which one is malfunctioning.

Once your CPU overclock is finished then its time to overclock the RAM. Raise the speeds back up, shorten the timings, and I guess lower the voltage if you can (1.6v sounds good to me). Less power = less heat.

Alriiiiiiiiiighty then, back to the OP problem. Sorry, but there was a lot going on there.

I don't even exactly understand the problem "shutting the cores down 1 by one saying theres an error on the core," but will stab at it. I suppose a picture of the error in Prime95 and all of your current specs might help us determine the problem. I'm assuming that this simply means your getting an error in prime95 and have to stop the torture test.

As always the answer is usually the simplest one and I have to agree with The Sandman and somewhat with jprovido.

If your getting errors "Without any Overclocking whatsoever" then the PROBLEM here is most likely either the RAM itself, a too low voltage issue, or a combination of both assuming the heatsink/cooler installation and TIM application is correct. I'm 50/50 here, maybe 60/40 leaning towards voltage as the problem.

As TripleC pointed out; the factory settings your seeing the first time in BIOS could be incorrect.

Step 1
Take the necessary steps in the above posts to ensure your RAM is good and eliminate it from the problem.

Step 2
Set your voltages to CPU, CPU/NB, DRAM, etc. accordingly. For example, just one click up of 0.003125v on my CPU/NB voltage made the difference between errors in Prime95 for me.


Your ball. Remember we work for Rep.

Thanks for all the tips everybody. Ill definately take a look at my ram. While running prime if I selected the test where it uses the least amount of ram then it seemed ok and wasnt dropping cores (I only ran it for an hour). Ill leave it to run all day today and see what happens. Ill back my voltages down on my ram to 1.5v and up the timings? So there 9-9-9-20 now where would I set them? My bad, I just read the above post again and he tells me exactly what to do. SOooooo Thats what Ill do. Ill report back soon. Once again thanks for all the help.

So I set my ram timings at 11-11-11-30 and bumped the speed back to 1066 and now its running prime without a problem. So what its telling me is that I either have bad RAM or its not configured properly correct? Let me play with the timings and speed a little and see what that does. Besides the DRAM Voltage what other voltages can I adjust to tune this sucker in?

Sounds like good news!

Leave the RAM alone with these looser and slower timings as it is now overly stable.

You should come back to the ram after your finished overclocking the CPU to your desired speed.

Now is the time to get your MAX (or desired) CPU overclock (with RAM not a problem now).

Keep raising the FSB and/or multiplier until you get errors in Prime95, then raise the CPU voltage a bit or two and see if the new error in Prime95 goes away and becomes stable again. Repeat. Just keep going up say 100 MHz at a time until you hit an instability wall, then lower it by 50 MHz, if successful now raise it by 20 MHz as this means your getting close to your MAX overclock. Next try the CPU/NB voltage, then the NB, SB, etc.

If you raise a certain voltage and nothing changes, then you've changed the wrong variable, so change it back and try another. Baby steps are the key here.

*I personally like to lower the multiplier a little bit first to acquire higher FSB and all around other speeds.

This process is very boring and you will need to play with the voltages quite a bit to find the sweet spot between max FSB and multiplier (NB, HT, etc.) speed settings and your enemies such as Prime95 errors (or BSOD) and Heat. Instability and Temperatures are your biggest obstacles to attaining a higher overclock.

Once you are settled in @ 4.0 GHz for example, then go back and overlock the RAM and run tests in Prime95.

We can conclude that the RAM was causing the instability issue in Prime95.

It was not configured correctly, at least not relative to your other non-RAM settings.

So I played around with the timings and speeds. Heres what I came up with. With it set at 1333 and 9-9-9-20 it fails prime. Change the 1333 to 1066 and leave the same timings itll run Prime all day. So whats to stop it from crashing when I set it back? Or do I leave it on 1066?
