Yeah, you are right about volts/heat, I wasn't aware that the modern CPUs could actually get that high, seems absurd.gunbo13 said:No, there is no cut and dry between the two. Increasing either area can lead to a CPU death as well as shorts, internal issues, condensation, leaks, and others.
I'm not sure where you read this but this effect is miniscule, usually only being a factor over years time with persistent use (if ever). You aren't going to see degradation after a few days of overclocking. Chips actually can have burn-in periods as well similar to RAM. I have had processors that accept greater voltage and maintain better stability after intensive overclocking over time.
Just an FYI for people, modern Intel CPUs are designed to handled thresholds 120c+. I've run an i7 without a heat-sink for a duration of time without issue. I put a strong warning of not approaching this number but these CPUs are built to handle high TDP.

Nah...and overclock.net isn't really a great resource...

Is there one for 6950 or 69xx AMD cards? I poke around but didn't see anything besides owners thread.koji said:I wouldn't go so far as saying P95 is retired, linx flags instability way sooner though but I've had errors flag with prime blends 6 to 8 hours in while my rig was able to do 50 maxed linx passes without issues. Also, linpack generates tons of heat, if you're cooling is not up to it long P95 sessions are the way to fly. (My personal way of checking stability is 20maxed linx runs + 12 hours P95 blends, but everyone has different opinions on that :lol)
OCN really was better a couple years back, but that could just be me feeling nostalgic. Whatever. Socket 775 overclocking was so well documented on there, socket 1366 as well. Can't say the same for SB related stuff though, but that might be because I never really bothered to look since I'm still on 1366. Anyway, there are still some gurus left in the motherboard specific threads but it feels like it's slipped a bit yeah. Might also have something to do with these new mobos and chips, everyone can OC now. On socket 775 you still needed to fool around with clock skewing and clock drive, the real OC voodoo, now it all looks/feels easy.

Must be a royal pain in the ass to change every ranking number manually What about setting up some kind of google spreadsheet thing? See that a lot on OCN. Probably easier to manage.

And why not? These latest processors are being overclocked to ridiculous levels without a steep learning curve. Most high clocks are just chasing numbers with really no practicality to 99% of users. In past generations, 100% overclocks were used to equal top of the line processor options or to achieve practical results. Now, 100% overclocks are for competition yet the idea still leaks to end-users. Which I believe is a mistake. You should be conservative since your gain is about zero and that is the right call. My 920 is a fantastic chip and I certainly have a history with overclocking. My current voltage? Stock.Hazaro said:Yeah, you are right about volts/heat, I wasn't aware that the modern CPUs could actually get that high, seems absurd.
I know some people pumping volts into the first gen i5/i7 (and ICH) and I believe some of the second gen i5/i7 had problems. Along with the fact people are running 32nm chips at the same voltages as 45nm is what makes me really hesitant about upping the volts even thought temps are in check.
So basically it is just me being conservative.
It's not retired but that doesn't really mean it is that useful anymore. Typically if linx passes you are not failing p95 on CPU stability but MB/RAM. I don't condemn the test because the more the merrier. But most overclockers I worked with graduated from p95 years ago.koji said:I wouldn't go so far as saying P95 is retired, linx flags instability way sooner though but I've had errors flag with prime blends 6 to 8 hours in while my rig was able to do 50 maxed linx passes without issues.

More heat means more stress. Avoiding that by using p95 is not the right call. If your cooling is not up to par with linpack, you have to step it up or dial back. Dodging it just means you are not achieving a proper level of stability.
Well I don't want to get into a big discussion here but if an air-cooled system can't dissipate the heat generated by linpack, it should not be clocked that high. These software packages don't cause higher thermal output by chance. One is stressing the CPU in an entirely different way, typically with more heat meaning more stress. So the only "option" in that regard using another stress test like p95, is to result in p95 stability. That doesn't necessarily mean your system is stable, handling all processing demands. It only means it is stable regarding a p95 test, which IMO is not adequate enough. I typically show a tiny grimace each time I see p95 stable for x amount of hours since I can envision the future problems for users.koji said:You're right about the heat, it's an option though, not a lot of air-cooled systems can dissipate the heat generated by hours of linpack on a seriously OC'ed CPU.
Your not causing any harm but I do understand what you are saying. The pain comes from people in threads talking about how their game crashes. Many times you read a statement such as "OK, I'm going to lower the clock speed on my processor to see if that helps." Oh great it works now! But was that really the overclock and not a false positive? Why are you even doing that and how were you operating with faulty settings? It makes no sense.lowrider007 said:Over the years I've really started to relax when it comes to IBT'ing or P95'ing my system for hours on end, my system is never going to be stressed like that in it's life, if anything I'm causing more harm than good, ok I may get a BSOD in the life of my machine, if that happens then I up the voltage or down the multiplier, the thing is what with CPU's down-stepping these days and with the offset voltages on the new chips your pretty much guaranteed stability for 90% of the time even without a serious bench test, with these new chips you only really have to worry about stability on high loads which for most people means gaming, and then you also have to consider that most games for GPU limited, so the gap for when you need true stability lessons and lessons for the average user.

Yup. GPU voltage I just cracked up to 1.3V pretty fast. Pssh, it's fine.gunbo13 said:And why not? These latest processors are being overclocked to ridiculous levels without a steep learning curve.

You just don't have to endanger your CPUs these days for 24/7 use. Now your video cards...those things should burn.
MSI Afterburner. You may have to modify your registry to get to higher clockspeeds.woober said:What program do you guys use to OC ATI cards? The ATI control center only lets me overclock a small amount.
Just waiting for the H60's(got 5 on order) to arrive. hopefully by midweekHazaro said:$1,400 in graphics and you still have a stock cooler? :[

OC that wolfdale chip, you should still be able to squeeze out more performance in a lot of games. I think 3d mark 11, like previous versions still gives out big points for having fast CPUs, which is why you're seeing low scores.whatsinaname said:P3909 - 1 x XFX 6950 2GB (800Mhz/1250Mhz/0.900v) - E8400 @ 3.03 Ghz - 2 x 2048 MB G.Skill 7 @ 400 MHz - Gigabyte EP45-UD3P - Air - Link
Damn, I am doing my 6950 a disservice by sticking to the E8400. But I play games that are 6 months - 1 year old, so don't really see a need to upgrade right now. Only reason I got a 6950 is because I got a 2560x1600 monitor.

So yeah, why does it say that my stuff is lower compared to similar spec computers, is it because I don't have my 2500K overclocked?
Just wondering.

Normal and not a problem. It's how the chipset splits up the lanes/bandwidth.bloodydrake said:Does anyone know if having 2 pcie slots running at 8x for crossfire would slow down dual card bench?
the Mobo I'm using is an asus P8Z68 DELUXE that says slot one runs at x16 with one card but with 2 cards slot 1 and 2 both run at x8.
or is this normal behavior.?
just wondering if this is part of the bottle next in the quad configuration.
