@0razor1

Im stable 3.8 v1.56 but I can play games and bench at 3.9 v1.65.For some reason I have more stability issues at 3.9 when watching movies or web browsing.On my old asus ddr2 board this chip would boot at 4.0 but no go with this one.I agree the h70 is overpriced but if you can find a h50 there great.I have mine mounted outside my case and can run prime at v1.65 and my temps never past 53c. now a couple questions
1.How much voltage did you try?
2.Do you think its safe to run such high voltage givin my temps are so good?
(changed tim on my NB/VMR ,and SB heatsinks and there are temp sensor's built in all over board that never past 41c)
3.If temps is the only thing I have to worry about how much voltage should I try?

High volts degrade your silicone over time --- not quite so with the CPU but significantly shorten the RAM , Mobo components etc...
1.65 is OK on WC . why not-- My recommendation == stick to the 3.8.. even 3.7 if that requires significantly lower volts ???
1. I went A complete 1.5 V up ( 1.4to 1.55) for a 100 MHz increment (3.8 to 3.9) FAIL-- maybe temp related-- but I dont think so - would happen randomly as load fluctuates-- particularly @ idle :/ can u believe that ?? I'm going to go out on a limb here and say that temps had abs nothing to do with it :/
2. Temps well, further dictate the life of the component. But just cause one could Liquid He his prooccy doesn't let him run >2V core right ??
Your chip need to have a high leakage tolerance , else the chip won't work well with high voltages ... I'm talking 1.4+ so thats not too much to go on- Every1's mileage may vary. You're running 45 nm.. anything over 1.55 V is harmful. Some may debate that but I have pretty strong opinions on extending component life-- overvolting and killing a processor, or any other silicon is easily detected and I like warranties.. Can't afford a new one tomoro if this dies -- absolutely no chance of an RMA :/
3. No you don't just worry about the temps. Worry about the volts..
Thermal dissipation and backward leakage current increase EXPONENTIALLY on increasing current/ volts.. so a 100MHz requiring a .9V boost :@ not worth it :/

FYI - the max volts on the new x6 has further been reduced-- gives u an idea of what harm it can do.

@0razor1 I will get that 2.6 or 2.8GHz one way or the other, dang it. Will get busy with that this weekend.

Yeah, the cpu is good. I almost love it. But why does it say 115.5W on HW monitor? And some of the other cpu monitors as well..
The temps are now at 39C idle/53C stressed. So it's not all bad. Running the AC freezer 64 pro at 100%. Still much quieter than the stock cooler was on idle.
Will try to read into the memory timings. But I am already way up the list on Everest.

I have AOD but I don't really use it for anything. I'll read that document over the weekend. I LOVE reading as long as I understand what I am read about. lol

You expect me to go higher with this cpu? I am wondering if the 80C on the 770 chipset is something that's holding me back.. But Gigabyte said it's normal. I would say it's a misread. Only a wild guess.. Fluctuates between 79-81C.. And I hate those numbers. I want everything to be

ok Won't get the CoolIt then. Don't want a lot of tubes inside the case so I just might get air cooling. Or I could put the comp outside. It's -15C out there now.

Thanks for the link on ram tweaking. Will read that this weekend also.

You just got yourself another +rep.

My pleasure--Thanks for the rep! Do know that the AOD guide is THE MOST CONCLUSIVE in house guide out there.. and If you can work with AOD, look no further Just change the preferences to advanced mode and then simply head over to the performance clocks/ tuning section !


Can't help it but this has really stuck a note Can't get it out of my head. If we can have pictures of Fugly gfx card here, then why not this ?

With the mobo and at the rate you're going (in a good way- the weather is now COLD, in the summers you're OC will fall, so read up now and oc now. Don't wait till the heat catches up wid'ya! instabilities actually start creeping in after the 50C mark on OC's , not on stock freq.s so while a processor may be rated to take upto 62C on stock, >50C when OC'd will yield funny results)

With regards to the NB, I honestly think 2.6+ is going to be a headache=- that usually requires 1.4v on th NB while the default should be 1.1.. and if 1.1 is giving u 80C on the NB then either attach a fan to it .. or ur mobo's dead soon. Could just be a badly calibrated sensor, I'd recommend using a thermal gun ( those fancy thermometers) to check temps manually.
Do you have good case airflow ??
Here I choose to take the safe route out -- 1.3V gives me 2.6Ghz NB.
1.45 Gives me 2.8GHz NB. Not worth it - heat-wise , and read below:

remember to some extent, an individual max OC ( minimal instability) of a ton of components ( the CPU , GPU , RAM , NB, HT etc ) together make for ONE UNSTABLE SYSTEM ( simply multiply like a 2% failure rate on 3 components tends to an 8% failure rate together =X not acceptable ). So if a pc is meant to crash once a month on 24x7 on ONE max oc component, then with 7 MAX OC components - besides the exxtra strain on your cooling and PSU, expect it to crash on an avg, once every second day or so :/ not cool eh ?
Now when i say maxx oc ... I mean the 3.9 u strive to achieve @ 1.6 ish not worth it IMO :#
Close to happy hours .. its 3:45 am here and must get a beer and sleep soon!

I'd like to keep pace with your OC'ing but I'm headed back to the hostel in a bit , and the net's pretty unstable ( blocked, honestly) there.. I keep circumventing it but then they beat me round it again and again. I've given up for the most-- So OCN will have to work on EDGE (miserable speeds) and so I may be out of touch come this sunday

That is a nice pic. Reminds me a bit about my imaginary girlfriend.

The NB sink is a bit loose, I noticed. Seems to be very common with these mobos. Why do they even use springs on the nb AND the sb? Will tighten it up tomorrow somehow. IF temps drop then I'll try to up it. At 2.2 now.. If not, I'll keep it at 2.2..

Airflow should be good. Or so they say, the people that's got the HAF Xs. Got another 200mm fan coming in tomorrow. And thinking about installing the gpu air duct. Should be able to cool off both the nb and gfx card with the air duct.

1 am here and I have to go to work in about 4 hours.

Good night y'all.

All u rich folks with your big guns... but u know what they say ...

Anyhow. Ht links are useless :/ I dn't really care abt them . they have mroe than enough bandwidth!

U DO OC your QPI/DMI right?? Cause officially DDR3 is only supported @ 1333MHz by both platforms, right?? :/ So we OC out NB's to get better perf. out of ram , and sadly L3 cache :@

So do we .. Can't we all co-exist
Cheers !!

Thanks for clearing that up for me.

On the contrary I like how this thread shifted into a Northbridge overclocking tutorial, and sadly it's all my fault.

Lol - i really did laugh out loudly a second back
well, kzone I think just went up from an athlon x2 to a 965!! Three cheers ??

It was obligatory for me to help w/ the NB oc'ing -whatever little I know. We started somewhere around the point where our processors were holding us back and how a processor's performance , and the ram's , is tied around the NB

And after we're done with the ram and NB tuning ( pcie too now , we'll repost our benches

Oh, and along came ash -- the bezels weren't aimed at you LoL.

So the whole thing's
Notice the hot chick (FOx) I just posted .. how's that relevant? Invites views and I'm hoping enough encouragement for someone to post something substantial about their 68xx cards-- like new coolers / mods etc..

Sometimes it's a shame we can't down rate people, because either this was a troll or just some fanboy comment. If it was a joke it comes off as a very bad one.

Ignore the troll.

DDR3 is only supported at 1333MHz but it can be OC'd in the BIOS, meaning the 2000MHZ memory you bought is useful.

NB overclocking increases bandwidth and throughput, increasing performance. I have noticed an increase in FPS and smoothness in games when I run several games/applications simultaneously. I went from 2000 to 2600 last week and am glad I did, for one my BOINC WU's complete faster, which proves there's performance to be gained.

You are dead against overclocking of the NB without actually understanding it, while it's true you won't experience a massive boost, it is enough, as far as I see it.

For questions regarding North Bridge, memory and CPU speeds please post in the correct AMD section.
