Help with overclocking 1100t

post #1 of 14
Thread Starter 
So over the past few weeks, I've been working on overclocking my 1100t. I've been doing alright, and have a stable OC now, but I feel like the voltage is absurd for the OC I'm getting. Right now, my system's at an OC of 3925 MHz via multiplier (19.5x). My voltage, however, is at a constant 1.472 (set to 1.450, but I guess that LLC is affecting this, which out of the settings Auto, Regular, and Extreme, I have set to regular). Can somebody give me some advice on something that I might be missing so that I can maybe get that voltage down and OC up (the former being more important)? I've turned off things such as AMD's turbo core, cool and quiet, and a few other similar things. I feel like I'm missing something. It's very possible that I'm not missing anything and just have a chip that doesn't OC well, but for obvious reasons, I want to try all that I can before accepting that. I've read several guides and just need some help at this point.

More specific specs:

Motherboard: Gigabyte GA-970A-UD3 (BIOS version F7)
Processor: AMD Phenom II x6 1100T
RAM: Corsair Vengeance 8GB (2x4GB) (9-9-9-9-24, 1600)
Cooler: Xigmatek Aegir

If it matters, my CPU/NB is at ~2800 MHz. with I believe 1.3 voltage. I have my HT Link kept at ~2000 MHz

Just to clarify, my question is this: Is there something that I can do to lower the voltage at least? Can someone point out a setting that I might be missing, a part of my build that might be messing me up, or give me a tip in general with overclocking this? If any more information is needed, I'll gladly provide.

EDIT: one more question. I track everything with HWMonitor just to see where temps and everything go. Why does it sometimes read my chip as getting bursts of insane voltage? I just saw it jump to 2.600V for a split second, and apparently it got 3.600V at one point? Are these just false readings, or is something going wrong?

i don't have any experience with overclocking amd, but it looks to me like you just got landed with a bad chip.

have a free bump, and good luck with further overclocking.

Try overclocking using the fsb instead of the multiplier so much, it may help. mine requires 1.45v for 4050mhz.

Those readings are just a glitch, if there was really 2.6-3.6v running through your chip, even for an instant it would be in big doo doo.

Yeah, trying an FSB overclock right now. Hopefully it goes well. Thanks for the tip.

And that's what I suspected, but I wanted to be certain.

Sorry for the double post, but got a new issue now: any advice on stabilizing the RAM? I keep getting the 0x0A BSOD. I'm underclocking the RAM right now due to the FSB. It's currently at 1332 MHz - would underclocking maybe make it unstable? Timings are still 9-9-9-24.

Should I try raising voltage on the RAM, messing with timings, messing with my NB overclock, or is it something else entirely?

yeah i managed to get a slight stability issue out of my system by bumping my ram voltage from 1.49 to 1.55

also i dont think you mentioned, what have you tested your stability with?

Ah, forgot to mention, sorry about that. I've been testing with Prime95 in blend mode.

And alright, I'll try upping the voltage next time I give it a go. Thanks!

cool ^^ how many hours you putting it though?

I also reccomend intel burn test. it will help detect any instability alot quicker than p95. I use it to test initial stability, and when im satisfied with the results i move on to the 12+hour grind of p95

also as a note, make sure your VRM heatsink has a nice supply of air. it took me a long time to figure out that one of my issues when getting my OC was that my VRMs were overheating and shutting down my computer.
scary to think of.

now i just have a side fan (which i neglected installing before due to no dust filter... but for the sake of performance > Laziness, i gave in) and also a small 80mm fan right on the heatsink at a low speed.
keeps it very cool and now i have steady OC of 4.1ghz + 2800GHZ CPU/NB

Volts are 1.485(bios) 1.5 (LLC load)
cpu/nb 1.35v
dram 1.55v 1333(underclocked from 1600, same as you, attempted to rule out as stability issue)

also as a note, i have the same ram as you, so your problems could be similiar/identical to mine smile.gif

Not many. I do around 1-3 hours of Prime95 just to test for initial stability, and then I move onto using my computer as I usually would. If I manage to go a couple of days with no BSOD and I'm happy with my overclock, I'll do a more intensive P95 session to further test for stability.

I ran Intel Burn Test today, though. Thanks for the suggestion. It showed up with my current OC being stable after a few tests on different levels of intensity, so I feel pretty secure now. I wish that I wrote down what I did with the RAM last night. I either overclocked my CPU-NB and raised the voltage a bit, or did something with DRAM voltage, and it seems to have worked so far. I'm currently sitting at exactly 4000.00 MHz, give or take about .6 at any given time, with the voltage fluctuating from 1.452-1.488. I'll keep working on it, but doing FSB overclocking seems to have gained some stability for me overall.
