Tjj226_Angel Posted October 20, 2011 Posted October 20, 2011 System: Cpu: Intel i7 950 Memory: 12gb Mushkin Radioactive memory Motherboard: Asus P6X58D-Premium Graphics Card: EVGA GTS 450 Superclocked PSU: Sunbeam 680W (this might be the problem) And most importantly the cooler: The infamous Noctua NH-D14 Hello, I am new to posting on the forums, but I have been reading and following the website for a while and I am hopping someone can help. I have been trying to hit a stable 4.0 GHz OC or more on my pc but I seem to be having a ton of trouble with heat and voltages. On idle on stock settings (and yes I tripled checked) I have been seeing temps without the low noise adapters for the NH-D14 of 40-44 C. The ambient temperature in my room is 22 degrees C. However, with my window open it drops down to about 18C ambient and with my PC case door open, it drops 1c.......... I have tried all conventional ways to diagnose the problem and with the D14, there is obviously a problem. Oh and it gets better. Even with it on stock settings and the doors open, running prime 95 STILL sometimes results in a bsod. When I over clock it, I can get a somewhat stable OC at around 4.0 GHz at Vcore 1.38. That is with turbo and speed step disabled. Prime 95 doesn't hesitate hitting 100c and probably more since the dial stops at 100c. The only thing I can think of is I skimped on the power supply. Before you all start jumping on me for skimping on the one thing that shouldn't be skimped I must say that when I bought it, it was on sale and rebate and yada yada ya. Being Christmas I did not think I was skimping, but rather got really lucky. So please forgive me. The proof that it is the power supply is that it doesn't have an 80 plus power anything. However, there are two other things it could be. 1 power supply, 2 case. I have the corsair 800D. These problems only started occurring when I put my system in the new case. I believe I have ruled out the case because I had the side panel off for most of my tests. Plus it only explains the heat, not the ridiculously high voltages. The 3rd idea I had was I had was possibly the thermal paste. I have built and rebuilt my computer I don't know how many times and I have never used rubbing alcohol to clean anything. I have always been extremely careful to clean it very well making sure there was NO residue what so ever and I have ONLY been using Arctic Silver 5 Thermal Compound. However, that STILL only explains the heat, not the voltages. I have been having voltage issues since day 1 but heat issues only a month ago. I give you such a lengthy and detailed description of the problem because I have narrowed down the problem a lot so that you guys don't have to do a lot of guess work. Even though I am betting its the power supply I still want to hear what the opinions of the members of the website has to say. Please help asap! Thanks.

Speedway Posted October 20, 2011 Posted October 20, 2011 Ok, first off Welcome to OCC You haven't given us an important piece of info and that is your cooler Next, 1.38V for a 4GHz OC on the i7 950 isn't too high, also here depending on cooling! If you are running 4GHz @ 1.38V and you are seeing 100C temps, then I would have to say that it is bad contact with the cooler, but, of course I would still need to know your cooling situation Share this post Link to post Share on other sites More sharing options...

And also if you still have the nth1 thermal compound that came with the d-14 then I would use that over as5. Hope you get it reseated OK and everything clears up.

Hyper Posted October 20, 2011 Posted October 20, 2011 Yea it sounds like cooler isnt seating properly or too much paste. Share this post Link to post Share on other sites More sharing options...
Tjj226_Angel Posted October 21, 2011 Posted October 21, 2011 Well I just got done reapplying thermal paste and it made a huge improvement to temps, but the voltages are still a problem. I mean seriously, no stable stress testing at stock settings? Something is just plain wrong. I did find one thing while I was playing with my heatsink and that is that I have a 4 pin power connector going to an 8 pin port. I am now 99% positive its the PSU. However I still want to hear what you guys have to say, and if you agree with me I would love any recommendations for a PSU. Share this post Link to post Share on other sites More sharing options...

I would not continiue stress testing untill you have properly connected all mobo power connectors. A thin layer of new tim and a heatsync blown free of dust, will always drop temps Also next time you post a new topic, can you please break up your writing to apropriate, logical sections, of a few lines each. It makes it considerably easier for everyone to read and more importantly understand. You are asking for a new PSU recomendation, if you are set on upgrading that do you know if you are going to be upgrading any other components in the forseeable future ? ie new gpu/s when the 7xxx and 6xx series are released next year.

Speedway Posted October 21, 2011 Posted October 21, 2011 I have a 4 pin power connector going to an 8 pin port Glad the temp problem is taken care of! Yes you are absolutely correct with the setup you have, you need a PSU that has a 8pin CPU plug supplying the power! Share this post Link to post Share on other sites More sharing options...
cirro Posted October 21, 2011 Posted October 21, 2011 use your system 4prong, get a 4pin molex to 2x4 for the 8pin VGA cards, seat them next to each other on the motherboard is if they were connected and go if you don't eel like dishing out the money for a new psu you can even get ones that start from molex flat 4pins and let that 4pain rail goto a videocard http://www.aerocooler.com/shop.cart?action=ITEM&prod_id=CBLMPCI4628 just google computer power adapter, and look through the various wiring that you can adapt i've OC'd a couple boards with only the 4pin running in the 8pin slot. some liked it, some didn't, but it isnt COMPLETELY necessary to run it properly Share this post Link to post Share on other sites More sharing options...

Not sure I would want to, even though it may work Share this post Link to post Share on other sites More sharing options...

wevsspot Posted October 21, 2011 Posted October 21, 2011 Give us the BSOD error code and also post up all of the BIOS settings you're using when attempting to hit 4.0Ghz. When I say "all BIOS settings" I'm only referring to those found in the Ai Tweaker and Advanced sections of your BIOS. Frankly, I think it's a combination of two things; your BIOS settings and your power supply. For overclocking a i7 950 you MUST have full power to the 8 pin ATX 12V CPU plug. I personally don't recommend adapters, but even that is better than relying on a single 4-pin. While the 4-pin may be adequate for proper operation at stock/nominal settings, it certainly isn't adequate once you start overclocking. The fact of the matter is (assuming that you have all of the proper power connections available and plugged in AND you're running the latest BIOS revision for your board) everything should be rock solid stable at BIOS default values. I've got a lot of time and experience with your exact board and it is a great board when everything is installed and configured correctly.

Tjj226_Angel Posted October 21, 2011 Posted October 21, 2011 I think I am just going to get a new PSU. I have an almost 1.8K computer and the power supply isn't modular. It is almost a sin since I have the corsair 800D as my case and you can see all the wires. If any one wants a laugh, I will be posting pictures of it soon and you can see how I used electrical tape for cable sleeving and some other sort of jerry rigged things. My goal is to sell my computer come Christmas time. I want to sell it as a pre-overclocked system to push some extra cash out of it. Then I want to invest in Ivy-bridge when they hit the market. If on a side note any one would like to tell me cheap upgrades I can do to increase the likelihood of making a good sale for Christmas, please let me know. Thanks so much for your help Share this post Link to post Share on other sites More sharing options...
