dont waste your time updating with my last results, due to the fact it was stable for 10 hours kinda made me pissed cause i knew i could get more out of it
so i found out 3780 isnt stable, and currently trying 3752, will have an update when i get off work tonight.
i honestly didnt expect this to be stable, no idea whats working considering a few weeks ago i couldnt get 3.4ghz stable at this voltage, lol.
Might be a bit higher then what it's showing maybe 10C higher then.Quote:

well i think my temp sensor is way off, the bios showed like 18C idle, when the room is 22, and when in windows its showing 23C which might be right, or the same number as the bios just 5C hotter due to being in windows instead of a bios. so when its at 45C i think its possible the cpu is closer to 50C, which is a the touchiest point for these chips. and i think i remounted and got much better contact so when i use to dump on that extra heat, it wouldnt go anywhere, and now keeps it cooler and at lower volts (thuban prefers temp over volts if i had to summarize it for someone else)Quote:

I was looking awhile back for a thorough article on NB frequency effects, and I just stumbled upon one (that's quite old, actually, don't know how I missed it) that does a good job of it:
http://hwbot.org/article/news/hwbot_...rmance_scaling
They even reference back to Xtreme Systems here
And here was my own personal struggle for NB frequency.
Bottomline, there is no universal ratio where anything less bottlenecks ALL apps. But, generally, you want to strive for at least 2:1 NB-to-RAM ratio (or at the very very least, 1.7:1, eg. 2300NB:1333RAM). 1090T owners have a supreme advantage here, since the NB multiplier on 1055T's won't go past 10x, so the frugal ones like myself are held back by FSB limits. But it breaks my heart (well, not really, but for dramatic effect...) to see a 1090T at over 4GHz, RAM at over 1800... and the NB still sitting at 2000.
are you sure about that limit of 10x? then i wouldnt be able to adjust my NB at all, since my bios is very funny. i cant lower it from stock, and i can only raise it at the same rate as my HT link. basically im just short on adjustment options, lol.
also, what do people recommend for testing turbo stability? something that only uses 2-3 cores at a time, without me forcing core affinity.
On the 1055T? Yes, I'm sure. The only way to raise it is with FSB (which starts at 200, then 10 mult =2000 default)Quote:

Regarding the HT Link: you won't see a benefit in performance beyond stock, but supposedly, for ultimate stability, it's best left in-sync with the NB freq (then again, for ultimate stability, AMD's current implementation of Turbo is best turned off... the proof is in the pudding: my out-of-sync settings are plenty stable), so if you can't modify the multipliers at all, don't sweat it.
So, at your current 257FSB, that means your NB is running at 2570... if you haven't already increased CPU-NB voltage, you need to do so. If you can't, then it's unfortunate, but you'll have to back way off on your OC. Feel free to flip your MB the bird.
As for the CPU frequency: you can generally get 3.6 to 3.7 on stock voltage, so you're fine there, but your turbo is probably giving you problems. Try setting the turbo multiplier to 15.5 for just-under 4GHz. Can't change that multiplier either? Well, then... feel free to flip your MB the bird again. (or just disable turbo... for the love of crap, please tell me your MB at least does THAT. If not, it's back to scaling your OC waaay back so that the Turbo freq is stable)

i can adjust my turbo multi, and i have that at 16 now instead of 16.5x so its right around 4.3 still. which has never really given me an issue, but i still havnt given it a good few hour test.
Not too much of a heat limit now.Quote:

My load voltage dose drop a bit 1.454 heavy and 1.464 sometimes.
make sure turbo is off as well, one time I forgot to disable it and it kept going into the turbo multipliers (default 16x) when I set it for 22x -_-Quote:

saint 19, looks good, only with 1.4V? Show more for us, maybe will great chip (1.48V and 4300 MHZ +???)

I was thinking the same about 4300MHz I will try it this weekend I hope don't kill the chip :rofl:
think not, 1.48V is safe for 24/7
pff, 1.7v isnt even a suicide run if you have water coolingQuote:

turbo adds like .2v to whatever your settings are. so stock it gives it about 1.5vQuote:

i would say 1.55v is probably the highest you can go for 24/7 and not get any degradation. 1.6 should be fine if you have water
and temps on thuban seem to be better lower in any case. as ive found out, any voltage you want, probably wont help if your over 60C
just read like everything from the very first post and it will give you lots of ideas for what is possible. (temps, clocks, volts, cooling methods, motherboards, max NB/HT, etc)
for Deneb up 1.5-1.55V (if your temps OK, means about 55-58C only) and about 1.45-1.488 for Thuban
i had come across a weird conclusion this past weekend.
my clocks were not being stable at 3.71ghz @1.368v. the temps would hit 42C or so which caused my fans to speed up, after a while it would stable out around 44-45C, but never more. but i got constant errors in y-curncher
so i dropped the voltage down to 1.346, and guess what, the temps never broke 40C (which is when the fans start to speed up), and after an hour or so i was still rock solid and temps still under 40C. its crazy to think that going down in voltage helped. but now my rig is completely silent, and seems to be very stable. i wont have time for the full 8 hours until wed though.
so my tip to people out there, max out the clocks on the lowest voltages first, and increase them later since its a very slipper slope once temps get just a hair too high.
Ok guys 4.3GHz @ 1.48V.

You can see more pics here
but what about some LINX or PRIME???
I will do this weekend, I'm waiting my C300 SSD to get better results. ;)
Quite tempted to grab a newer batch 1090t, now a days the majority seems to do really well with low voltage :)
Hi guys.
If I run LinX 8+ I must run y-cruncher too, or with LinX is enough. What are the advantages of y-cruncher?
1023GPMW | 24 degrees ambient
http://b.imagehost.org/t/0145/4_1GHz.jpg
I'm not finished with it, but it seems that it's weaker than my 1010MPMW. The real voltage was steady all the time (1389 - 1391mV).
At least it runs cooler. The fifth core is the weakest one, others don't need this vCore.
Seems a good start Ivan. 4.1G with <1.4V is not too shabby is it? What's default Vid?
Yes, not that bad, but not better than the other one I have. I think most of the new 1090T can do the same with water cooling. Default VID is 1.3V, if CoreTemp is a good way to see it. It idles at ~1.28V (multimeter) with "auto" set in bios.
The first test I did was to put it in the socket and see if it's stable with the settings I use for the other one. Well, it locked up. 4.3GHz is doable with around 1.5V real voltage.
It doesn't mean that It will remain the same when an overclocked CPU-NB is added to it.
I've already read tons of reviews on the Crosshair IV, so I was about to pass this by, but I thought I would take a look at their overclock:
http://hardocp.com/article/2010/11/1...board_review/7
I was always curious how some were able to exceed 300fsb, beyond just luck. Well, I found my answer: "CPU VDDA voltage", or, on other boards, CPU PLL voltage. I generally leave PLL voltages alone, but it looks like this particular setting helps with high FSB overclocks (also see their MSI results: http://hardocp.com/article/2010/07/2...board_review/1, again, higher CPU PLL voltage)
Even with my posted stable settings, I found myself sometimes being booted to desktop after long gaming sessions... lowering the FSB one notch sorted that out. After bumping the CPU PLL up one notch to 2.54, it looks like I can go back to my initial "untested" settings of 289fsb... I just past a 50-run on IntelBurnTest this afternoon. I'll do a 400-run tonight to confirm and update this post.
***Update***
Bah. 289 didn't pass overnight testing. Even 288. Back to 287. Looks like my RAM is at it's limit. Dropping timings and clockspeed down and upping CPU PLL to 2.7 for a max-fsb-test got me to almost 300, but it would not perform as well as my highly optimized timings. So, I'll stick with what I got.
They didnt seem to tweak the CPU-NB any with 1.45 on the CPu-NB I figured they would make a little more head way on the CPU-NB anyways I will give the VDDA voltage a go and see if it stabalizes things for me.Quote:

Quick question, should I lower my ht link speed on that overclock? I notice a lot of people have it around 2100, I have mine at 2700.
ht link is for cpu to graphics, which is quite fine even at 2000, so i would say yes, but after some testing.
some people i believe notice a loss in perf if NB and HT are not identical. not sure how true that is.
but lower the HT might let you get some extra clocks out of it. i would just drop it 1 multi so your around 2300-2500ish
darn double post
match HT and NB. in everest you'll notice cache and memory latencies improve quite dramatically.
Alright thanks, I'll play around with it then to see how it goes.
Can you give me some proof?I have same board as you,only i got 955BE c3.I have a pretty good CPU-Nb,doing 2800 1600 6-6-6 full stable at 1,25.But there is no difference if i match HTT with CPU-NB or not,it gives me zero performance,no difference whatsoever.Maybe it has something to do with Thuban?If you can give us some Everest screens would be great :DQuote:

I have read it alot on here especially with the 890amd mobo's, I tried it myself and it turns out to be true, When overclocking with FSB on a 1055t its best to keep NB and HT sync on 890amd boards, but if are you going to you'd need to increase PLL voltage and NB/HT voltage.

Nice chip there.
I have a question for the CH IV guys. Just started playing with this board and it seems to over volt quite a bit. For eg. for 4.2 Ghz, am running prime and it moves from the 1.45v i set in bios to 1.50V....now thats a huge movement in voltages. This is basically becasue of CPU load calibaration being on. When I put it off, it undervolts and basically black/blue screens during testing...Damn I cant get the volatages to be stable. On my earlier board, the MSI 790FX GD70, it would undervolt a bit, but would generally stay in the same range. In this board, it either undervolts or overvolts a lot. Now the issue for me is that even with a water cooled system, I am touching 60 degrees on the cpu when running it at 4.2 Ghz 1.5V (1.45V in bios). Can someone help me here.
Are you wanting to replace your previous entry with this?Quote:

Here's where I am . 3 hours prime 4.06 ghz. Set to 1.385v in bios. With load line went to 1.41v in CPUZ. CPU NB at 2.7 and ram at 1800 CL8

Next up 4.2 Ghz.
Without load line, the board tends to under volt a lot and that kills stability.
Oh, I see. In the future make sure to mention that it's a new entry / chip as otherwise I have no way to know. The only reason I asked in this particular case is because the clocks were lower. :) I'll hold off until you're ready if you still need some time with it first.Quote:

looking good :) if you click the link in my sig it shows voltages i needed for clocks ranging from 3.2ghz to 4.3ghz (which will obviously be different than yours) but more importantly it shows my temps at said voltages which might give you some insight. my water is also listed in my sig, both rads using 100+ cfm fans for those tests thoughQuote:

Is NB multi locked upwards for Phenom 1055/1075?
NB multiplier is locked only +upwards. U can chage it down (clocked this CPU with busspeed)
Hi guys.
Currently I have a Gigabyte 890FXA-UD5 with a 1090T @ 3.8GHz, NB@3000 and HT@2000MHz, the voltage are: 1.325V for CPU, 1.150 for NB and 1.375 for CPU/NB. Some people has tell me that run the CPU/NB with a voltage above of CPU voltage is dangerous, Is that true?.
I think FlanK3r meant those non BE-processors, which have locked multi.Quote:

Running up against some sort of hard wall. I can do 4030 at 1.45V and pass 10+ hours of OCCT, but 4100 is a bust at any voltage, NB clock, or memory clock within seconds to minutes.
temps are too high
Mid-50s? Nah, that's pretty comfortable. We're talking about +70 MHz here.
A load core temp of 55 or so is typically where Phenom II's, including the X6, start getting unstable.Quote:

Frick'n heck. I'm already using a Tuniq Tower 120 Extreme with two Scythe S-FLEX G fans.
Do you have 80+ CFM of exhaust fan(s) on the case to go with that?
The case is skeletonized. It's completely open.
I think my chip is high leakage. vid at stock is 1.275, will sometimes drop under load to 1.257.
right now I I just did 4.0ghz with 1.38 4 hours volts dropping on load to 1.332. :/ LLC is disabled.
My Nb is at 3.0ghz on 1.3 volts too.
Finally got this 1090T straightend out. :up:
For some wierd reason it didn't want to play well with my Corsair Hypers reguardless of timings. Swapped it out for a BBSE kit and all is golden!
I can probably tighten mem timings, but after all my hassle with the other kit I wanted to make sure it was out of the equation.

I don't usually either, but I thought I had it stable until it kept throwing errors in WCG...Quote:

I know I seem like sort of a hard-ass when it comes to stability requirements, but it doesn't do us much good if we list unstable clocks in the chart as stable. The whole idea is to give people a realistic idea of what are fairly reliable trends. You can see the discrepency, too, as I did even with one 1090T I used. It would run great at 4.2 GHz. I played games and whatnot. Turns out it wasn't actually fully stable above about 3850. It would do a reliable 7-10 minutes before crashing most of the time, so it was probably a heat management problem. People like us tend to run chips like that all the time. "Seems fine for daily use" but not actually stable for one reason or another.
WCG is a good test, but it's hard to translate its usage scenario into a formal requirement for validation. It doesn't really have a "prove to the user it ran full tilt for x hours" burn-in mode that can be nicely captured in a screen shot.

I could've gone higher but It would've required more voltage. Not bad for a 790XT AM2+ MOBO with a simple NB cooler and no VRM cooling (added some little copper dudes). Got another radiator coming in in two days, might decide to push a bit more if temps drop any. All fans are on low and case is open right now because of troubleshooting. 600W Rosewill PSU is pushing it as it is (smoked up the other day), so I don't want to stress it yet. Waiting on a new 1200W Mushkin, came in today and popped right off the bat w/ stock settings. I think I can probably suicide a 4400 on this thang but I think I'ma stick to 4.2. There is certainly still headroom although vcore is high already.

Charts are up to date now.
Added a neat new core clock vs. vcore plot on the OP. It is automatically updated with the other charts.
Sample:
http://www.pcrpg.org/pics/computer/o...replot_all.png
cool chart, now i wonder if anyone is going to try and be the first 4ghz stable with 1.4v or less
Wow. There is none yet?
Can i enter with my deneb? :D
4GHz with less than 1.4V is really no problem :) There are many chips which can do it.
Could be easily marked as stable @ close to that frequency if I want to. And that's the weaker chip :p
I'm sure it can do 4GHz full stable with vCore lower than 1.4V.

its temps dont even go up before mine has an issue, so i know its not cooling related.
My 1055 behaves similarly. I don't get much past the point where all of the cores jump up to 100% on the first pass of linpak at 4Ghz with anything less than ~1.45v.Quote:

so i might bump up the clock later and try again. but right now im scared to look at the power draw. a decent OC is 200W load, the highest i pushed was 250W, this has to be more..
Try 1.45?
200W load? I see 400W at the wall max under linpak with the video card idle! I see 110-115 at idle.Quote:

My 1055t needs 1.5 set (droops to 1.488 load) for 4004 mhz. I thought it was stable with 1.475, but the 3d11 physics tests, of all things, required a bump.
it passed the 8 hour test, so i officially have 4ghz stable YAY, SS saved so ill have it all updated later tonight.Quote:

and with 4ghz 1.476v it was 265W
i tried to find out if i can do 4.1ghz but at 1.488v it still wasnt happy, and i really dont care about having such a high clock anyway, its just too loud to keep it cool. i was thinking about doing a quick review of power consumption relative to performance across the whole range of voltages from 1v to 1.5v. but if i have the time for that, i should probably be working on other things, lol.
I am officially claiming the highest ddr2 overclock. :D Just need a new power supply so I can test stable and go higher!
I think mine managed 6hr stability... I'd need to check... no idea where my post has gone with it <1.4v
[EDIT] Can't find the 4Ghz at 1.38v but I did find the ultra low voltage 4ghz run - benching stable but not prime stable XD
Asus CHIV for me Phenom II 1090T @ 4Ghz :)
