[OC log] (\/)0n0L17(-) II

i'm stable now at 3.4Ghz, but it's coming at a price... my load temps are hitting 80'c as my volts are up to 1.45v now. Don't know if i'd be happy pushing them much further, so I think i'm going to drop back down to 3.3Ghz @ 1.4v for everyday use. I'm going to investigate also if there are any other settings I can change, besides CPU volts, that can stabilize 3.4Ghz.

Ok, well after hitting a thermal wall at 3.4Ghz, i've decided to, for now, get a working everyday overclock, which means seeing if my RAM can run at its rated speeds with a CPU overclock, and if possible have a CR of 1T (should be very possible) At this level i've already tested what is the stable voltage for both my CPU and RAM so if I run into any issues now, another variable will be at fault, more than likely the NB temperatures or voltages.

I had to increase the multiplier to 13 as I tried 300*11 (3.3Ghz) but this gave me a QDR of 1200 which, for some odd reason, my system can't boot at. This would of been a perfect option as it gives me the stable 3.3Ghz and a DDR of 800 for the RAM, but c'est la vie :rolleyes: At a multi of 13, my clock is 3.25Ghz with a DDR of 800. I'm going to stress test this setting, then lower the timings to rated, then try 1T. Once I get a stable everyday overclock i'm to see about pushing past 3.4Ghz. I've noticed that increasing the multi to 13 has risen my idle/load temps higher than what they where at 12 @ 3.3Ghz, so maybe the high multiplier is the cause of the horrible temperatures.

I'm going to drop it down to 9 and start upping the FSB instead and see if there is any change in temps at 3.4Ghz.

whats with the weird images from everest? you know you can just click the "save" button and save it as a png file.

whats the rated timings and speed of your RAM? Do you have 4GB or 2GB?

Here's an EVEREST bench from what i'm at at the moment.

Hey L31mr0d, I was trolling a bit and came across this thread. I haven't overclocked a machine since I pushed my Wang 386SX 16Mhz to the limit (about 16.1Mhz) so, I was wondering if you could give me some pointers as to how to go about cranking up this beast.

My rig is in my sig - any help much appreciated.

Cheers.

Well this thread really was written as a guide. Just follow the steps i've taken here. Your experience will differ, but the procedure is still the same. Start up a new OC log and give all the relevant details including pictures of your BIOS settings that relate to overclocking, and then just ask questions on the BIOS settings that differ from mine. First off i'd run a 8 hour memtest86 stress test then run a 8 hour OCCT (or multithreaded prime) stress test to make sure everything is rock solid at stock settings. Better safe than sorry

Ok i'm back. I kinda left my clock where it was for a while to actually use the PC for what I bought it for... to play games.

But now i'm back and even more confused

I'm going to try overclocking again but this time try and keep the CPU multi as low as possible and instead overclock via the FSB

I dropped the multi to 6 and started overclocking the RAM again. This time I was able to get it stable at 940Mhz.

These are the results in everest:



These results are pretty good. I don't know what the multiplier was doing but it was destroying my overclock. Funny thing now is if I increase the multi past x8 I can't boot?

Does anyone have a clue why this would be happening?

Havent a clue, Have you tried the evga forums?

Ok well I tried the evga forums and someone over there mentioned that a possible cause could be that I needed to increase my SPP or MCP voltage as increasing the CPU multiplier would be pushing a lot more traffic through the NB. Not knowing that these voltages had anything to do with the NB (it isn't exactly clear what they do, I had thought they related to the HT multiplier) I remembered something about the issues i'm having. In memtest I wasn't getting any RAM errors the screen would just freeze, the same happened in Vista when I ran OCCT, the test wouldn't fail only the screen would freeze. This reminded me that this is a sign that the issue is with the motherboard and not the CPU or RAM (otherwise a CPU or RAM error would be generated)

So I proceeded to increase the SPP voltage and finally got the system stable with the x9 multiplier. After some more testing today I eventually got these settings stable after a half hour OCCT run (will run a stress test overnight tonight)
