Hopefully that will improve temps somewhat.
Anyway, I run the fan at 100% because I can barely hear it with my headphones on, and never when I'm playing sound through them. It doesn't bother me as background noise. At stock, after hours of BF3, I get 59C load, with 45-50C on the VRMs and Memory.
Because of these, I set the voltage straight to 1200 (1650mem) and then clocked it to 1200/1600 to start with. I've yet to try it in games, but here is my Heaven run with temps. I'm sure I can go higher with that kind of voltage, but this was just a basic overclock while I waited for something to download tongue.gif I'll be testing properly later on. Looking good though!

Thats a good OC. I need 1.225v for 1.2Ghz. I am even in Water with MAX Temp @ 50C.

So I found two things about my current set up .. that helped with crashes .. I'm on rc11 + 12.2 caps, disable ulps, AB unoffical overclock @ 1200 |1625

first I loosened up my physical RAM timings ... while the system was stable .. it just seemed to help stop crashes ... went from 7-7-7- 21 to 8-8-8-24 -2n

And I rolled back to AB 14

Also switched my monitor connection from DVI-D to This display port cable

so far no hangs or freezed on BF3 -- but I guess it's a lot of variables too rolleyes.gif

also I love my H100 ... but you can do better than the stock fans they provide... I just used their TIM and it worked great on my i920 @4.4 it's rarely sees 70c on loads and idols in 40s ... lastly you can plug the fans into your mobo or I did into my fan controller ... this way you can adjust as needed - gl

I am on 12.3, straight onto a fresh Windows install, no RC11, with latest CAP. It's so far run BF3, Skyrim, and MW3 just fine with no overclock. Hopefully I won't see the issues others have had with unofficial OCing on 12.3. I realised I didn't have tesselation on after I did the test, but it doesn't matter as long as I use the same settings for every test, so I can see when performance starts to take a hit. Once I've found my final OC I'll do a run with normal tesselation so you can see the proper score smile.gif

With the H100, I've bought two 3kRPM Scythe GT's for it, and I'll be setting it up in the top of my case, so the GT's push and the stock 200mm exhaust pulls. I already have a D14, so I don't expect to see much of a change in temps - I got the H100 because of space and aesthetics. The D14 is such a pain to work with and I've just got sick of having to remove it every time I want to do the slightest thing, like reseating my RAM.

I'm not bothered by noise so I'll probably just leave the fans running at max all the time. I tried using a custom profile on my Lightning but it was leaping between 20 and 100 every few seconds so I just leave it at 100 now. Card didn't want to play nice frown.gif

Wow, goodoh then! I'll likely be overvolting further, VRMs are so cool! I'll try to keep my core under 80C though. Keep in mind I don't know if it's game stable just yet - I'll be running BF3 later in the day, too busy right now frown.gif

Since the PSU is old, you may actually be having PD issues on some of the insulation of the components. The PD could be causing spikes on different voltage rails and such, causing the random instability. The problem with PD is that, it appears to be completely random but will get worse over time until one fine day... bzz... pzzz... dead PSU. In my line of work I do deal with it, but on a much higher scale. The fact is, PC PSU's basically being rectifiers, they are still subject to same electrical stresses over time. I bought 1200W even though I know I would barely touch 800W simply because the components are designed to handle the higher stresses. Keeping them on, but not stressed highly extends the useful life. Since you've had problems since you got the mobo, could it be the mobo? If you could eliminate the variables by isolating each and every one (if you could borrow a bigger PSU maybe you could test and see if it's the PSU). you should be able to get to the problem. But with ASUS Sabertooth, it being the mobo is really doubtful.

Ye i had kinda the same problems with my first 1155 mobo, bought a gigabyte one that was just buggy as hell, but that could also be because of the psu. Now everything is new, new gpu's, new ram and so on... BUT, either way i just ordered a new Corsair hx1050w silver one, 300 dollars up here. :S Worst case scenario then i'll ship it back since they have a 45 day "open buy", dunno what you guys call that tho smile.gif

I actually have a mate with the same mobo, and kinda the same problems. A bit to random ? Dunno...

Could PSU cause random spikes in amps at high overclocks? Cause while watching GPU-Z the other day I noticed some strange spikes, while under load jumping from around 165A-160A constant to 185A-190A randomly.

"It sounds like your drivers are set to auto update. Check to see which driver version you are on now. As for the overclocking problems, the newest drivers removed files necessary for clock control. You can add them back in here."

Thank you very much TSM106. The AMD catalyst update patch worked perfectly, and put my 7970 back into top form. Totally relieved!thumb.gif

That's the exact DP cable I bought for my 950D...

I wish I had the consumer protection EU and the US enjoys. When we buy things here "Goods sold are not returnable or exchangeable". You buy it, you own it. Gotta really think before we buy anything. RMA is fine, no warranty issues as that's from the manufacturer. However, for items with more than 1 year manufacturers warranty, there's a handling fee of about $10 (US) for processing. I recently RMA's my old Logi G500, had to pay the fee, but of course since it's Logi, they gave me a brand new G500. I do wish we had the consumer protection US and EU enjoys though. Could've swapped my 7970 for a 680. I'm so thoroughly pissed with AMD and the drivers crashes right now. Have programmes running just to stop Zero Core from activating.

Ye, we are lucky with that. Where i buy computer stuff isn't the cheapest place tho, but the upside is that its great service and warranty. Been thinking a bit on changing my 7950's for 680's, but i've had them to long now and need to sell them, which i will lose money on, so i'll stick with em i guess. Downside of living where i live is price on stuff, my two 7950 are 1400 dollars smile.gif

Ampere jumps are normal, sudden demand from the load is non-issue. You need to be worried about the voltage though, minimal ripple in voltage is always what we want, which is where the Corsair PSU's excel. I got the CM cost it was significantly cheaper than the AX1200 where I live. But the AX1200 price just dropped to about $10 more than CM a week ago and I'm kicking myself for getting the CM now, but a Gold certified PSU, is still gold certified so they're still good. Sorry, sidetracking there. Watch your volts. If you're seeing drops in the volts, you'll be seeing spikes in the amps as well, that means the load's constant and you're having voltage regulation issues. It could be some the diodes in your PSU rectifies are having problems. If you anything where you can observe the actually PSU output DC waveform (ie. oscilloscope) it would be quite easy to diagnose the problem.
