***955 Unleashed***

[chew*]

I was lucky enough to get my hands on one of these 955's early and whip up a review for launch day.........enough chit chat lets see the star of the show and what it can do.....

First I'd like to note I swapped to the latest publicly available bios on gigabytes site for the ddr 3 board.

Special thanks goes out to MsiMax who helped out alot with the LN2 results.....He has quite a few of his own results if he can find them

I saw a lot of shots like this and I personally disprove of them, not real world at all..........Yes you can do 4 gig on stock volts..........however lets see what it takes for true stability........

Prime stable, true stability at its best, seems the 955 is definitely a cut above the rest.......

I decided to test out the IMC and do some ram clocking....and whoa :eek:

The IMC is tuned well for low latency ram and will do far better with slower speeds and tighter timings.

http://members.cox.net/hoobahans/955%20review/955%20air%20ramclocking%206.jpg

Some more ram clocking although I admit I didn't put as much effort into this one.

2 x 4850's X fire World Record ( cards unmodded and still on air ) I forgot to bring the cpu speed back up with K10 stat, speed was 6.1gig as you can see according to 3d06 ( we were booting at this speed ), bug with gpu-z overclocking cpu when you open it causing a crash forces us to downclock.

Summary.

It has been a pleasure working with the 955 Retail and in all shapes and forms has exceeded the clocks and performance of the ES chip I have been working with.

I'm quite sure there is even more potential in this chip just waiting to be unlocked and looking forward to benching with it some more in the very near future.

[cdawall]

very full review chew* i'm going to get some DICE runs in tomorrow but i somewhat doubt i will even come close to you good runs just wish you had a smidge bit better ram for some of the tests. hit me up in a PM and i will see if i can find you some good HCF8's or D9JNL


mind if i post my results in here?

[Tom128]

Nice, hoping to get a 4Ghz 24/7 clock on water when I get mine. Seems feasible!

[Movieman]

Very nice numbers!:up:

[cdawall]

Nice, hoping to get a 4Ghz 24/7 clock on water when I get mine. Seems feasible!

it is temps under 40C load should allow 4.2ghz 3D benchable, 4.0ghz stable

[[XC] gomeler]

Very nice start :up: Looking forward to these chips, hope to have one next week on LN2.

[overclockedamd]

OH ya baby. Cant wait to get my hands on one of these. Got dozens of pounds of dry ice available from a local shop.

[_d_]

thanks for very full review sir :D

[Akrian]

Holy :banana::banana::banana::banana: , AMD strikes back =). Now I'm tempted to get one of those. is it possilbe to pull 3.95-4.0 Ghz on AIR for 24/7 ?

[Oldguy932]

So pretty much this 4.1ghz phase cooled one isn't really going to be that fast compared to most people now. I guess I know what I'm getting the week after finals :D

[bro20000]

I cant wait to get mine now! Nice Review!

[msimax]

the 955 are awsome little buggers

All set on ram, dont let those gskills fool you.

I benched with them for a reason to give a real world view for most users and what they can expect to get or better.......

It seems I've run out of email addreses to validate my air 4.5 validation........Used the wifes one to many times.

Will get it sorted in a few.

[tbone8ty]

is it possible for these NB speeds on my older Asus M3A32 mobo? (sb600)

nice overclocks chew.

im excited!

[Akrian]

Chew* , what Vcore would you suggest to use on those sweet 955's for 24/7 ? ( I couldn't find the official specs on AMD site )? I mean looking at your tests , even if I reach stable 4.oghz on air it will take awfull lot of Vcore volts to do the trick.

[dennilfloss]

Thanks for all the charts. :)

The initial Canadian price sucks! Better go down in a couple of weeks. :(

[64NOMIS]

Incredible Work. Comprehensive results on stock parts. Outstanding.

I have been waiting a long time for this part to launch - it's a great node and the NB has huge potential at cold temps.

Congratulations.

Really depends on chip but 1.520 seems to be the max needed for 4gig....It took me 1.575 to get my 940 stable at 3840mhz..........I think it can handle the volts as long as you cool it properly ;)

wow very nice guys

[Akrian]

since I'm a bit tight on my PC budget, after getting all this expensive INTEL crap last october ,I will be stuck with my old MA32 Deluxe ( wi-fi) edition. It died on me couple of months ago ( or that was my CPU 0_o) anyway I'll RMA it tomorrow and hopefully all things will work out .:yepp:

[richierich]

wow

[chew*]

I just wanted to add I ninja'd this into my max cpu-z validation........take a close look at HT speeds.............

Yes there is no issue and you do not need to underclock HT one bit.......there is no spoon and there is no coldbug.............the limits you create are within yourself and nothing more......

[SoF]

wow very nice write up chew :up: great results and sure I now wanna have one :D

[Oese]

w00t i have only one question: why are these online shops in germany so damn slow with making this available to ME :wall:

Hope i'l see one here on saturday or at least next week....

[quake6]

Great results :)

@msimax: on what mbo was that results? Very nice NB clocks ;)

Chew was that with the T.R.U.E. 120?

[eXzato]

:eek::eek::eek:

[chew*]

Chew was that with the T.R.U.E. 120?

the air results yes.....A lapped true 120 without a lapped cpu....probably fare better once cpu is lapped.

Thats great news then cause mine is lapped

Well after seeing what this thing does im changing my M/B lol

[chew*]

Just put a 955 up for sale btw get it while its cheap ;)

[FlanK3r]

congratulations u Chew! Nice overclock. I hope for x4 955 BE next month (price come a little down, i hope). Can u say me, Gigabyte MA790X-UD4 AM2+ support X4 955 or not? I wrote to gigabyte and they wrote back me this :

"Dear Michal,

Thank you for your kindly mail and inquiry. About the issue you mentioned, GA-MA790X-DS4 supports AMD Phenom II X4 945 / 955 CPU since BIOS version F7A, please update your BIOS to version F7A for supporting this CPU."

but i have not 790X-DS4, but 790X-UD4...

[adam9977]

Looks good...thanks chew* for the excellent review! Now I see how long I can last before i break down and buy the 955. I made it a whole week after release before getting the 940!

[Entropicity]

Very niceeeeee :D

Thanks for the air results.

[gaidin]

mmm cant wait to get one of these in Aus :yepp::yepp:

[G.Foyle]

Excellent post Chew*, and great results too :)
How some people find time for LN2 before the launch... I've had a real writing marathon.

[ZoLKoRn]

Very nice work chew* :up: and thanks for sharing ;)

btw. i got it yesterday and will update some results soon :)

[=SOC= Admiral]

I am definatly going to get one of these to replace my X3. Sadly I have been having some stability issues that 4 freaking tests werent able to find. but it could have something with my CPUvid not being at 1.525 for stability and my 1200's filters were full = No air = one a hot a pcb. Now the question remains how much am I going to charch my brother for my CPU.

[chew*]

Very nice work chew* :up: and thanks for sharing ;)

btw. i got it yesterday and will update some results soon :)

You saying I need to grab a third card or just break out the mods and chiller :D

Seriously though I think I will flash these back to a normal bios and retire them......they earned there keep.

I have other toys to play with that require my abuse and undivided attention anyway.

Congrats chew* & MSIMAX for bringing us this fantastic OC review!


PS. @NOMIS64 how long I will need to wait for RB-C3 and/or 6 core desktop CPU? :)

[Oese]

955 on the way i'm curious if mine can get anything close to 4ghz...

[suphiceto]

Chew, I wish you have never touched one of these chips!! Now I see the true potential of it and wishing that I had one of them!!!

Very nice clocks and results!!

BTW, I waited untill 1 am last night to see some reviews but coulndt find anything and now there is all kind of reviews out everythere. Crazzy!!

[haylui]

wow...so many 955 in the wild already....

[imamage]

May I know what code you got ??
Mine is 0911

[shaolin95]

I PMed Chew on his 955 for sale...doubt I am lucky enought be the first one to ask. :-)

[Aquineas]

Seems that the reviews on this are topping out at about 3.7-3.8ghz on air. Not bad, but 4.0ghz on air would be nice...

It was brought to my attention that most reviews were done in 64 bit........so I revoke my comment.......Really not sure why they would choose to use a non mainstream OS however.......32 bit is still mainstream 95% of software still is to.....how many years after 64bit was introduced?

There are alot of factors......how familiar someone is with the architecture and how well they know the board they are working with, how cool they can keep the chip ( etc are they using a stock cooler ) and how much voltage they are willing to push......or in certain cases are they pushing to much voltage.......not all chips like voltage....not all chips are equal...are they trying to crank the bejeebus out of the memory.....an unhappy IMC makes for an unhappy cpu, unhappy cpu's dont clock to well........

[Aquineas]

Loose nuts behind the wheel IMO.

Oh I totally agree, and I have no doubt that you having the experience you have can get superb numbers, but for blokes like me, I'm no expert OC'er and I have never been able to get above the average, so I try to use that as barometer. Just me setting realistic expectations. It's a bit too easy to come here and see what some of the experts can get and get ones hopes up only to get disappointed later.

(Note I also prefer to run with a closed case).

(Note I also prefer to run with a closed case).

Tony ( OCZ ), I and a few others plan to simplify this in the near future, it just takes time and alot of testing to make sure all info is accurate and presented properly......

I'm quite sure that with water or a good cooling setup my results can be duplicated.......I used my single scythe kaze fan with a lapped true 120 and unlapped cpu ( not an optimal setup ) exclusively during this testing to keep it a little more realworld this time around.....No delta fans ( plus my fingers cant take the abuse anymore )

With a decent push pull setup in a closed case with good in/out airflow I don't see why 4.0 stable is not possible.....key things are using vid cards that exhaust heat out not dump heat in the case.......

I will be rebuilding my everyday average normal system with AMD in the very near future and I will be sure to document some real world results ;) that system runs a q6600 btw and while I saw many struggling for 3.6 gig 24/7 stable mine cruises right along at 8x450 ( and i'm an intel nub but I know how to OC ) everyday all day and all night with a 1600 rpm delta fan a lapped true 120 and an unlapped cpu.......in a rather restrictive cm 690.......

[Tony]

So I got playing and posting now the embargo has lifted...http://www.ocztechnologyforum.com/forum/showthread.php?p=377706#post377706
I have the new beta bios from MSI which is quite nice (wait for msi to release it) and have been testing to see whats easy and what is hard to achieve. I was also using a new kit you will not find on our website but we are just seeding to stores...2000 cas9 rated micron for 1333 cost sure is nice..only issue is its a TRI kit for i7 but its cheap ;) LOL

Im updating on OCZforum...its open for discussion or we can talk here, no biggy to me ;)

short of it for now...forget running sill;y ram speed for 24/7...its just not worth it.

[Particle]

I don't think you give 64-bit enough credit, Chew. With even OEMs starting to ship 64-bit editions of Windows and enthusiast PCs often containing enough RAM to pretty much mandate it, I think we're starting to see some pretty good adoption.

[chew*]

Very very nice tony :)

I see forced adoptation.....I see rigs sold with 64bit to unknowing consumers........I see very little software companies backing it......I see lots of driver issues with it.......I see the need to add yet more hardware that is not necessary...........8gigs of ram is a niche crowd the majority will never need 8gigs........not that there aren't apps that can't benifit.....but there are far more that don't...

I'm oldschool though, I refuse to jump on the latest and greatest till its tried and true.....I still use PS2 mouse and KB, I'd use win 2k if it recognized 4 cores.......I still use IDE drives and cd roms...You guys want to be paying beta testers have at it more power to you....I just want my pc to work and it could do so in 8bit mode for all I care as long as it works everyday everytime without aggravation......

If I want aggravation I use my bench rig.....

You forget that 99% of people actually using computers do not know how........they know how to surf the net, dl :banana::banana::banana::banana: and viruses.......

64bit is hard on these CPU's when overclocking, voltages need to go up and heat output rises also.

I tested 64bit and lost 200MHZ as same voltages to 32bit...there is work to be done to make thing equal that's for sure.

I like 32bit though as i TRIM the vertex no sweat LOL...I like things fast all the time ;)

yup 64 bit tough on clocks.
isn't anything that is only 64 bit it's all still 32 bit
still waiting to see a game designed for 64 bit

I refuse to use non 64 bit OSes.

BTW chew: I hit 3920 stable under Vista x64 in my review. XP 32b is 4 GHz stable with some more voltage.

This is wrong on Phenom II(or it is on my Phenom II 940 BE and Dfi 790FXB)

I can run max 24/7 3.7ghz in Win Xp sp3 32bits and runing same in W7 64bits without any troubles in game etc.

And also 3DMark2006 do not lose over 0-100mhz from runing in WinXp vs W7.

Maybe you cpu is bad or something, or doing something else wrong?:) , but mine dont lose anything in W7 64bit :)

And all this is with same settings in bios.

rubbish...every reviewer I work with said the same thing as i have.

I needed higher voltages to have 100% stability for same clocks within Vista 64 period.

both my CPU's are good, nothing wrong with them. test with a 955 and you may find the same.

Lets see some 06 3dmark score clock per clock.......I can tell you just going from win xp to win vista or win 7 32 bit mind you there is a 400 point drop in cpu score...last time I checked the reason for upgrading is higher performance.....not to lose it.....when I gain higher performance I will upgrade my OS........unfortunately I will be forced to use vista 32 for 4870x2's.......but I most certainly won't like it......

[shaolin95]

Well I can share my experience...I can do the same 3.7 or 3.8Ghz with 4 cores on my 720 in either Vista 64 or XP Sp3 without any changes and stability is the same.
Then I try Windows 7 and it will blue screen. 3.6 is the max I am getting stable under Windows 7. I didnt bother trying to give it more voltage as I saw no point to it.

Yeah...i lose around 200mhz with my Phenom 9950

on vista 32bit it does 3.6, but 64bit vista gets it down to 3.4

this is 24/7 stability though, not sure about SS but it should be similar

So I got playing and posting now the embargo has lifted...http://www.ocztechnologyforum.com/forum/showthread.php?p=377706#post377706
I have the new beta bios from MSI which is quite nice (wait for msi to release it) and have been testing to see whats easy and what is hard to achieve. I was also using a new kit you will not find on our website but we are just seeding to stores...2000 cas9 rated micron for 1333 cost sure is nice..only issue is its a TRI kit for i7 but its cheap ;) LOL

Im updating on OCZforum...its open for discussion or we can talk here, no biggy to me ;)

short of it for now...forget running sill;y ram speed for 24/7...its just not worth it.

Hi Tony!

Nice thread and test. I think that I'll register myself on that OCZ forum. :D Can so called Animals do 1600/CL6 in GD70? :) Btw the MSI has just release two new beta BIOSes. 1.35 and 1.36

Unfortunately I could not read your reply (if you replied back) because the recent PMs have lost. :shakes:

[Tony]

I have 135...136 just adds clockgen support as far as I know so its no big deal. The issue is they are releasing bios every day so im not getting to involved testing untill they slow down.

The MSI is looking llike a great board though, it feels like a DFI to use ;)

Regards CL6 at 1600, not tested yet, what I do know though is CL6 may be slower than Cl7 or 8...we have something to find in this MCH as it does not work quite like we think.

Animal does not like over 1.67V on the MSI....so its not worth ramming juice.

Hey, there's room for all of us here. I use 64-bit operating systems AND PS/2 keyboards. :D

Besides, I wasn't saying 64-bit is necessarily better, just that it's seeing more adoption than I think you were suggesting irrespective of its benefit.

[Sparky]

I used to use a ps2 keyboard but it wore out and I couldn't find another that I liked.

Ahh but you can say its better is some things man....I get my butt kicked by cinebench in 64 bit, sick numbers, I just wish all apps were across the board faster......that would give software co's incentive to code for 64 bit.....at that point I would make the shift.

[Lastviking]

rubbish...every reviewer I work with said the same thing as i have.

I needed higher voltages to have 100% stability for same clocks within Vista 64 period.

both my CPU's are good, nothing wrong with them. test with a 955 and you may find the same.

Maybe Vista is one thing but W7 64bits vs Xp Sp3 32bits i dont lose any mhz....so trust me its not rubbish i have tested it many times becuse i dont want spend any more money on a new cpu so i make many test with the cpu i have instead. And dont tell me i´m a newbie then you geting the wrong dude.....but all can make misstakes thats true :)

And i dont trust reviews...many times the abit wrong from the real world.

But you did say 64bit vs 32bit in your first replay and not Vista 64bit :) , so it can be a point there with Vista.

But you can always send me a 955 so i can test it :rolleyes:


Edit: Did a fast super pi1m in W7 64bits @ 4.0ghz with 1.47v without any trouble....to bad i need go to work now but i will post it later and more test for you Tony.

Well I can share my experience...I can do the same 3.7 or 3.8Ghz with 4 cores on my 720 in either Vista 64 or XP Sp3 without any changes and stability is the same.
Then I try Windows 7 and it will blue screen. 3.6 is the max I am getting stable under Windows 7. I didnt bother trying to give it more voltage as I saw no point to it.
Regards

Had major stability issues in win 7 as well, couldn’t even get 3.6 to run stable. Have to give it another try further down the road, when it’s a bit more mature.
But I see no difference between XP and Vista 64, although I can’t really test it accurately on this board.


And nice clocks chew, as always :)

Wez was the 32 or 64 bit?

We wil be benching either vista or win 7 32 with crossfire X 4870 x2's (whichever gives us better results) however we have already near matched our XP speeds......we had to back of the NB clocks 200 mhz.....in win 7 before and that was it.....core clocks remained identical with identical voltages.

Early Am and still at it, getting prepped to test 4870x2's out......I think any power issues we may have had are a thing of the past ..........

Thats why High volt d9's are not my cup of tea to bench with cold.....I'd rather take a small performance hit and bench 16 hours straight with a set of rock solid stable sticks rather than to waste DI or ln2...

Not to mention that they ( D9's ) are known to Bug out when cold.... now you know why I didn't bench LN2 with them ;) and why I only pushed the ddr II d9's to 599 instead of higher...I should have backed off them more......validations would have passed........on phase and DI.

QFT. Sorry for taking this further off topic. I just see no reason in 64bit OS until there are apps I'm interested in (games) are 64bit and run faster because of it. Never seen any game requiring more than 1.5Gb of RAM. 4Gb in XP SP3 works very well for me.

Back on topic. 955 looks like a beast. Would have switched if I had slow CPU.

[Lastviking]

64bit is hard on these CPU's when overclocking, voltages need to go up and heat output rises also.

I tested 64bit and lost 200MHZ as same voltages to 32bit...there is work to be done to make thing equal that's for sure.

I like 32bit though as i TRIM the vertex no sweat LOL...I like things fast all the time ;)

"ok" here is the image....And YES maybe Vista 64bit is harder but it dont looks like W7 64 bits are than Win Xp.

I will not install Vista and test.... W7 works fine for me :)

And this is not the limit i think... it was a fast test if i remember right 4060mhz was max in Win Xp 32 bits, if you realy want to know if i can do same in W7 64 bits i can change the clocks for you :)

temps and have you tried less voltage? I found when I first played with these I was used to chips requiring higher volts.....I backed off volts eventually and it was smooth sailing from there.......Optimum temp range for prime is under 50C...

I know with the 940 no matter how cool I got chip it electrically it could not pass prime at 4gig.

Also you will want to do this with ram and NB and HT backed off......eliminate everything from the equasion......thats how I test cpu's, Once you know cpu can pass you work on everything else individually until it starts failing.....this makes it far simpler to diagnose individual problems...



Lastviking the key to your 64 bit stability could certainly be the fact that you are running 800 ram speeds.......Might be on to something here.....

[Oese]

temps are around 50°C core and 45°C board cpu diode.. i will lap this thing of course ;)

i tried less volts but not with -% acc perhaps that'll gonna help some..

right now prime runs at 3.8g @ 1.425v.. nice as well..

Somethings is not right with 1066 ram speed... i will try to figure it out, it will make WinXp crash after sometime and also corrupting files, thats why i have left it @ 800 speed now. Dunno know if its are the IMC, Ram, High vdimm or something else. But my sticks are rated 1066 2.1v 5-5-5-15

Just playing with mine now.

M3a79T deluxe 0803 bios. Single 4850 gpu modded for low idle power. Water cooled.

For a quick start I used the bios settings from my 720 and trimmed back the multipliers. 3.8 looked ok in Prime as did 3.9. I could not get 4.0 to prime for more than 15 minutes so switched back to 3.9 for a while. As the 12v line was showing 11.6v I checked the plug in watt meter. For reference the 720 idles around 150w @ 3.8 1.55v, the 955 @3.9 1.55v is idling at 220w, up to 380w under prime :eek: As my Tagan psu is a 450w model and prime @ 3.9 has just failed at around 1 hour it looks like I'll have to break out the 750w Seasonic :eek::eek:

Silly power draw for 24/7 operation. If I can't get below the 180w idle mark at 3.8 then this chip will be looking for a new home :shrug:

I found it better in my test a while back on my 940.

Supposed to be but I can never get ganged to run stable on giga, unganged is better for everyday use.

[Particle]

What is a safe upper limit on the CPU/NB, for reference? Pretty much the same as the CPU cores?

Attempt #2:

Doing better, but still unganged. Having trouble with NB overclocking. The same question still stands for voltage, btw, if anyone knows.

http://www.pcrpg.org/pics/overclock/18.081.png

[ecat]

CPU/NB it was around 1.4 iirc on the previous PIIs, I think I remember gotVoltage at 1.5v, definitely worth a quick search on his user name.

The last time I enabled ACC to see what it did I discovered an extra core. No such luck this time ;) -2% All looks promising, +2% All looks promising, either appears to stabilise my cpu at 3.8 with 1.425v set in the bios - I'll investigate further. A short time playing with ACC is not helping at 3.9GHz and the slippery slope of more and more voltage looks unavoidable for the moment.

My 720 hit its sweet spot at the same frequency, something to ponder. 5:30am, time for bed.

Can somebody tell me what s happened?

Sorry the broken english and thanks for all

[leoy]

I think that this has happened before...
It's propably due to the fact that the boot speed and tha actual speed is very different, cause u propably used k10stat or AOD to reach that frequency.
I think chew has reported that, and he is more appropriate to answer.
Try booting closer to the validation u try, and do the last mhz with aod or k10stat. I think chew said once 400-500 mhz is the limit before cpuz rejects the validate. So booting at around 5.7-5.8 ghz should fix the problem. If that is possible, and if this is actually your problem.

[Particle]

I haven't figured out the magic either. It rejects tons of valid results from everyone. I've NEVER gotten a green submission, just yellow or red.

[G.Foyle]

Particle, I have found unganged to be faster in 16M. Don't know about 1M.
It's also easier to stabilize - to get ganged stable at 860 7-6-6-16 I had to mess with drive strenghts on M4A79T Dlx.

The cpu if not stable will do this, this is my findings.......In my phase and DI validations I was being conservative with voltage and running my ram cranked.........this is why My validations failed, the IMC was under some stress and I was using minimal voltage just what I needed to pass benches........

I also notice this with people trying to validate 1 core..........fortunately for me I don't bother with 1 core validations.......so mine pass if I'm stable....


CPU-z will only accept your highest validation and one email address per account.........In my case I used 4 email adresses for review purposes......however my main email address was the one I used for 6.4 gig validation..........and unless I break 6.4g it will not accept another submission under that email address......

might be ram placement bud, try swapping dimms? some ram like front banks, some like back.

[Oese]

Glad there are overclockers that can duplicate my results :)

but with 0.05v more voltage sadly..

[chew*]

but with 0.05v more voltage sadly..

Yah it will definitely vary among chips and motherboards but my guess is none of them will need more than 1.55....

From my experience its 1.475 to 1.5375v, 1.55v didn't appear necessary.

The good news however is No chip prior to the 955's that I used could pass prime No matter how cold I got my room......I think one time in the winter I had 5C ambients.........electrically the cpu's could just not get prime stable............now even at much warmer temps they can.....


BTW AOD temps are off, part of it's gigabyte, part of its an old version.......Ive taken ambient temps and aod temps and cpu was 4-5C cooler than ambients.

[ecat]

Looks like progress all round, 4.0 eh ? Well let's see where I'm at :rolleyes:

First, I have to say that using the 955 makes me appreciate just how smooth and easy my experience was with the 720. That poor little 3 core cripple always tried its damnedest to make my wishes come true. The 955, well, it's a bit twitchy and I'm starting to think the m3a79T deluxe is a little twitchy too.

After my hissy fit last night I got the 955 looking 3.8 stable at sensible volts by using ACC. -2%, +2%, auto it didn't matter and prime ran for 6 hours as I slept. So ACC helped, or maybe it didn't, it certainly shouldn't, but maybe it did ? Certainly the power consumption dropped a little when I enabled it.

I set out this morning with a plan to test the stability of all 48 basic ACC settings. Not a very good plan. So, I thought, if ACC is dropping the power consumption why not just boot to bios, set the values, reboot into the bios and look for the settings that give the lowest power reading ? Meh. Maybe not the best of ideas but it sure beats 48+ hours of watching prime.

Well, I have the 48 measurements here. In fact I have over 100 measurements. A very strange thing happens with my set up when ACC is enabled with one or more values not equal to 0. With various peripherals removed and ACC off or = 0,0,0,0 the measured power while at the bios cpu settings screen is 230w +/-1. Change a setting and reboot, the measured power is now around 218w +/-1. The sort of thing I was looking for, but reboot again without making changes and the reading jumps back to 230. Repeat as many times as you like, whatever non-zero values you like, the sequence is 230, 218, 230, 218 etc. Even if it is inconsequential I still find it curious.

Anyway. Much messing around later and I have changed over to my 700w Seasonic, 670w at 12v is making for a much more enjoyable experience. Watching it closely I think even at 3.8 the Tagan was nearing meltdown, 12v rail drooping and efficiency shot to hell.

After 24 hours messing around I'm now happy the 955 can at least match my darling 720. Nb doesn't like more than 2.4, even getting the fsb to 266 has been a chore. 4.0 ? I'll see what I can do, though it may be best if you don't wait up.

[chew*]

Yah little tip, Look at my prime screenie......NB adds heat , I removed memory and NB from the equasion......as I've tried on other cpu's.......All I did was clock the core, under clocked HT and NB a tad and undervolted NB a tad to remove some heat ;)

Really not sure if its going to be possible with NB speeds up as i didn't try.

Might be better suited on watercooling or phase to get both core clock and NB(IMC) clock both at high speeds....

[Rolle2k]

Have anybody tested DDR2 ram overclocking with a Phenom II X4 940 vs 955 CPU? I mean if ram/nb overclocking is better or worse since there now also is a DDR3 controller on the cpu.

[XRogerX]

ok just to add to chews post here is a test i did with the stock 940 and the 955

i cant post links cause the drivers for the 4890's isnt approved

Now the good news is as you increase cooling capacity there is no need to go easy on the NB........

Ok, I'm about to give up. Even with everything at stock settings and the NB just set to 2200MHz and 1.45V, it starts to cause errors. My NB hates me.

I can tell you that whatever your memory was doing before you will need to retune/tweak it particle........Memory is THE KEY to overclocking all phenom II's, the happier you can keep the IMC the higher they clock with less effort.

Remember my stepping thread?

Take a look at your cpu and see what changed ;)

last we were working on a CV memory controller revision

These chips are CY making them different even from the 720be memory controller.

You need to start from scratch, try swapping memory in dimms etc etc

I was having same issues until switching bank locations for my dimm's. If you already tried that I dunno then:confused:..

[Particle]

I switched banks and am having trouble just POSTing. I'll continue to play with it and see what I come up with.

[Particle]

Ok, I've started over from scratch. With DIMMs in the alternate banks (the far set), I've been doing better. Ran six passes of threaded mode Cinebench R10 x64 without issue at 2400MHz. Thanks for the tip, charged & chew.

[Particle]

Something else that keeps throwing me is that often the M4A79T won't have video on startup but is otherwise running fine. Windows will boot and everything but no video. I'd been clearing CMOS, but I think pulling the power entirely has the same effect, I can boot with video again. Simply turning off the board doesn't work.

Any beta BIOSes I should know about? :)

Six runs at 2600 and boot at 2800. Testing with 2800 in a sec.

[Slappa11]

Hey there chew. Slappa from OCN here.

Very incredible work. I too, had the privilege of getting my hands on one of these early. Here is my benchmark thread (just air results) http://www.overclock.net/amd-cpus/497132-phenom-ii-955-benchmarks.html

However, on both my MA790FXT-UD5P gigabyte board, and my A79A-S, I cannot get 4GHz 100% stable for the life of me. It seems that the further I raise the voltage past 1.488, the more unstable it gets. It is odd.

Like you, I could hit 4GHz on stock volts (which of course isn't stable). I believe my chip has the same potential as yours has, but there must be something I'm doing wrong. I tried everything I could think of. From raising the HT Ref clock vs just multi, loosening ram, upping different voltages, using odd combinations etc.

I'm running:

955
A79A-S or MA790FXT-UD5P
DDR2 800/DDR3 1333MHz
TRUE 120 w/ 2 fans in push pull. Temps are great.
Corsair HX520W PSU
Tried in 32bit XP, 32 bit vista, 64bit win 7, no luck

I'm not worried about the actual time. I'd spent all day chasing issues that in the end came down to the psu, I just wanted to see if I could run something at 4.2.

A side note on SuperPi 1m, tweaking the 955 3.8 settings as close as I can to match my previous 720 3.8 settings the 720 puts in better times. Much to learn about this new memory controller.

[Oese]

what you guys think is better for performance.. 1333 cl5 or 1600 cl7??

everest is reading about the same, actually 1333 cl5 is slower in bandwidth and about the same in latency curiously... but i would think 1333 cl5 is better...

Slappa, try dropping your NB (IMC) speed a tad and NB vid voltage, some chips just add way to much heat when you try to give it NB, Also you might want to try backing off on ddr 3 clock speeds/timings.......

I have found it necessary to increase NB not NB vid voltage to gain stability at 1600 and up ddr 3 clocks, especiallly when trying to run tight timings ( 1.28-1.30 )

[chew*]

nice... i cannot boot into xp.. @ same speeds that i can prime in vista 64 and i dont get it.. someone any idea why?

probably its the hdd.. incompatibility or something...

XP boot is harsher and creates more heat than vista/win 7 if you can believe that.......we have noted this quite a few times when benching on LN2, XP load screen is the equivalent of like running cinebench/Wprime 1024 M, I have no explanation why but it definitely puts a strain on the CPU.

Try booting in cold, etc with the PC off for a while.


I found 1333 5-5-5 to be less strain and easier on the IMC.......in my comparsion I think it was 1 sec slower in 32m and the 1600 ram clocks had a 30mhz advantage in NB speeds.........so the 1 second could be contributed to that.....

[xPliziT]

I am having issues getting a higher NB aswell.
As soon as i raise the NB mulitplier just one step the board refuses to boot.
Even raising NB vid and stuff causes no boot, but still working on it.
Running bios version 1.2.


So far got my system memory stable very easy which i did not expect for 8 GB :D.

running mem 8GB at 7-7-7-24 all 4 slots populated.

1 sec lower in 32m is more or less nothing. whatever my ram needs > 2.0v for 1333 cl5 so no option. try 1333 cl6 now with 6gb..

i really never experience such boot problems with xp. it was always easier compared to vista 64. but perhaps you are right and the system is better on 64bit and so the harsher boot sequence comes into play.. i suppose you compared with vista 32bit?

whatever its for benches only so i do not care that much.. but nice to know..

Compared to win 7 32bit, should be same as vista.......win 7 32 burns more ln2 altogether but winx xp32 literally boils over the ln2 pot at load screen........after boot we use less LN2 in Xp....temps diff between both OS is about 2C within the same benching session, just swapping HD's....... Mind you this is with a Kingpin pot we have noticed this with, and the Kingpin pot handles loads very well........so to actually see this temp increase with that the load has to be very intense.....

It would be safe to say win vista32 and win 732 run the cpu hotter than xp32 for 24/7 usage......but cooler on bootup.....


I've noted this on air as well with a temp probe attached to side of IHS....I have temps on these down to a science now, I know what temps benches will fail at, prime will fail at and how bad temp monitoring software via aod and or bios is off ( etc its innacurate ) I tend to be very very thorough, some would even say that I'm some what anal.........

If the side of IHS is hotter than software I can imagine how warm the core temp actually is........

Here's an example of how "anal" and thorough I am...... Im sure some of you may have experienced a crash with cinebench.........sometime you will blue screen, somtimes you will just black screen and sometimes the bench will just crash ( dissapear, etc just shut down ) and windows will still be up...........the blue screen is NB vid/IMC memory related, the black screen is core clocks/cpu voltage related and the just crash/dissapear from desktop is temp related.............

[Oese]

probably i try with aod one time.. boot into xp at lower speeds and then push it afterwards..

I tried this, and still no dice. I'm just stumped. Tried with both boards again as well.

It is not my ram causing instability, it is just the CPU.

Even raising the voltage on the cpu to 1.55 is more unstable than 1.4V. It's weird.

Just a quick update on my chip:
3.857 appears optimal but even this requires 1.4375 v for stability.
2.66 is looking to be good for NB speed, I'm working on the voltage, at 1.2875 for now. 2.394 was fine at 1.1125 v, 2.926 failed at 1.3v.

I can make 3.99 stable but I need 1.5125v to do it. A big jump. 4.0 fails at this voltage.

I'm messing with 266 ref speed due to the 3.99 testing. I'll play with lower ref speeds when/if I get around to it.

Of note perhaps, and I'll have to retest my results. At same cpu speed, memory settings, NB settings my Pi1M results do appear slower than those of the 720be :shrug:

Exactly how much slower? Is this using the same RAM and Motherboard? If so, I would assume its due to more cache efficiency with the 720 being divided just 3 times instead of 4 with the 955.

On the ddr II version I was using the Test 1 bios.....only bios I ever received from gigabyte......I gave them the go ahead to release a few weeks after I reviewed it.......It would not be released as T1 however........It would be released as F for final ( and a number ) My guess is it was already released prior to me testing it.....As F1

On the ddr III board I used a f5d which isn't ready yet for ram clocking, I spent 3 days tweaking that ram and did not have another 3 days to spend on ram when I recieved F3L public.......all other results and LN2 results I did on F3L (public) however......

I can't leak bios's nor would you want me to.......We managed to kill an MSI and cpu on an early bios ( under extreme conditions *LN2*) ...........I managed to kill 2 hd's on a couple bios's with gigabyte right after a flash.........Never got out of bios, never made it to windows.....and almost took out a 3rd ( brand new velociraptor )

I've been using an old version of K10 stat and 2.14 AOD all along......it works so I have no reason to change.....if its not broken don't fix it..

Make sure when you flash you disconect power after the flash, remove battery, and jump clear cmos...........I only trust the clr cmos button for clring my settings.....on the same bios...

F3 is most likely T1 if the release dates are the same.....

Come to think of it I now remember I had the same problem......with the shipped bios........I am going to email gigabyte and have them remove a few unsafe things and get the T1 out........please be patient not sure how soon they will get back to me........

Thanks, mate! :)

In the mean time, I'll keep fighting with the BIOS at hand... :bsod:
I'll keep you all posted. :yawn:

[mcbalaban]

Now I'm totally puzzled...

The BIOS says 0.975V, AOD says 0.975V, but the Black Box HW monitor and OCCP say 1.35V - and it actually IS 1.35V! :confused:

Right now I'm testing stability @ 3.2GHz and the "so called" 0.975V, and so far it's looking good with the core temperature at 45 degrees.

The problem is, AOD (version 3.0) isn't displaying nearly half of the needed options, so if I do any serious overclocking, I'll have to reboot every time... :shakes:

EDIT: Seems to be stable @3.6G with "1V" (1.375V according to OCCP). Temps are 49 degrees.

Chew. Are you able to get the 790x version of the board to test? I would like someone like you to test that board and get bios updates for it.

[chew*]

Chew. Are you able to get the 790x version of the board to test? I would like someone like you to test that board and get bios updates for it.

I dunno, best bet would be sending an email to gigabyte requesting this....

I personally don't like asking for stuff........If they send it to me on there own accord fine but I rarely ask for anything.

Case in point I needed a usable with dual slot vidcards 4X PCI X slot board...I purchased it ( MSI 790FX-GD70 ) even though it really isn't in my budget.

[ChrisB17]

Dang I just ordered the 790x and I am worrying about how it is going to OC my sig rig.

[chew*]

Well try emailing them, worst they can say is no. Be happy to test it for you guys and help get it up to speed......

[ChrisB17]

Emailed them. I didnt know your name so I just put chew*

[ChrisB17]

If the 790x board I ordered is a huge pos then I am going to get the 790fx version of it.

Sorry for the double post.

[chew*]

I tend to find the boards with less gimmicks, and less onboard stuff tend to cooperate better and get better results upon release......The more "crap" ( for lack of a better word ) that is onboard means more coding and the potential for more conflicts......

Would love to see a company put out a stripped 8 layer board with really well implemented and beefy PWM's but unfortunately it's a niche market......not realistic in terms of cost versus sales.

I think RD 580 reference was one of the few that fell into that category.

[ChrisB17]

Well the 790x doesnt have any gimmiks IIRC. Its just a straight forward board. Hopefully it isnt a POS.

Random observation: Virtualization with Hyper-V is excellent with the Phenom II processors. I ran Cinebench R10 both native and on a virtualized OS running on top of Hyper-V Server 2008. The scores were identical.

[cdawall]

Do you know whose fault is that? CPU or motherboard/BIOS?

mobo BIOS my chip did the same thing until BIOS1001 on my M4A78T-E and a later BIOS on my crosshair II both read pstates wrong and set the chip to 800mhz .975v

[Tomasis]

If the 790x board I ordered is a huge pos then I am going to get the 790fx version of it.

Chris B17, please to OC this mobo hard. Im waiting :up: If you check of villa1n's result, it is not so worrisome, I think. But we just need see more details.

I hope that Gigabyte gives chew a mobo so he could compare this to bigger brother UD5P. Let's say UD4P has less gimicks, so it clocks more well? Im not sure. Somebody said that the chip is produced at 65nm :shrug:

[ChrisB17]

I got the new DDR3 version :confused:

[Tomasis]

I got the new DDR3 version :confused:

it doesnt matter. We need see how much "abuse" it can take. IMC/NB, power circuity, bios or whatever. if ddr2 clocks well, so the chance is that ddr3 does it too, earlier or later. Memory clocking matters how well bios is optimized. Am I wrong?

[chew*]

Are P-states ignored if you turn off C'n'Q?

NO, depends on motherboard if P states work correctly, I never use CnQ.

You will likely find that the "good" chips have a higher tolerance for voltage. On ln2 that chip will most likely rock.

Seems to OC about the same as my 940, maybe alittle bit more tho.....955 on M4A79 mobo,
On water also

might have to sell this chip...lol

you selling a 955? BTH, I haven't seen you in a while, how's it going

[HondaGuy]

you selling a 955? BTH, I haven't seen you in a while, how's it going

Been playing around with this chip and yea its about the same as my 940, maybe cuzz of the mobo and DDR2 ram.....Probably would OC better on AM3 mobo....Yea.I would sell it, even tho I just got it...

I know really havent been on here much lately, damm work has been getting in the way.....Our new SUV is coming out soon, The new Terrain, and also the all new Equinox..... Back now for awhile so I thought Id buy a 955 and try it out..... I think its needs a new home

Hey Chew,

I was marveling at your 6Ghz benches.. those are just insane. I do have a question.. I am trying to figure out your vCPU and the other voltages, but I do not see anything in the thread. No AOD Screenie, or list of your voltages.

Do you think you can share that with us trying to join the 6 Jiga Hurtz club.

- Ton

[chew*]

Voltages in CPU-z are accurate.......Other voltages I used I would really not know till I load the profile again. Working on another board and diff ram atm.....Look at last 2 screenies of 3D benching @ 6+ gig. Really doesn't matter though, voltage required is chip specific.......

Honestly those having trouble reaching 6 gig are most likely trying to force feed a ram clock the processor just doesn't like......I tested with diff ram, and diff chips.....the lowest I was able to acchieve was 6.2+ when the IMC was happy........when I tried to cram a 1800+ 6-6-6-18-24 with d9's at high volts the cpu flipped me the bird........

Really not to keen on giving out my LN2 bench settings anyway, no offense but hours, days weeks, months have gone into them.......I have no support hotline, I earned them with hard work and dedication........I have no problem dropping a few tips or hints here or there........and have, just need to read my posts ;)

Prime stable settings I share........

[G.Foyle]

It seems most Phenoms II need around 1.8-1.9 V for 6+ GHz.

[chew*]

Yes but not all. Some don't like more than 1.7v.........Best thing I can tell you to study the CPU on air/water and find out what makes it tick.....I know exactly why any bench fails now and what it takes to get it to pass from just studying......

Here's one of my tips....last paragraph...

Not really, if you set up the system right, 1.65V~1.7V will get you above 6.2 just fine.

1.6v on mine to get 4.8ghz under DICE still working on that wonderful 5ghz :p:

Hey Chew,

I tottaly understand that you don't want to share your "Secret Sauce". I wasn't asking for a complete dump of your bios seetings. My CPUz reports 1.35v, no matter what volts I put in BIOS. So mine is never accurate. If I adjust it in AOD, it adds to the voltage i put in BIOS. So seeing your CPUz.. wasn't sure if it was correct, but since you say it is.. then I am good.

Yah saying the asus voltage is off is an understatement, the gigabyte is spot on though. Not sure about the MSI yet.

[mcbalaban]

NO, depends on motherboard if P states work correctly, I never use CnQ.

I tried battery removal thingy too - no joy. :(

I sent a mail to Gigabyte, but no answer yet.

Is there any one else here with a GA-MA790FX-UD5P motherboard using the F3 BIOS downloadable from the Gigabyte website?

Chew, are you sure it's the BIOS fault? If so, I'll patiently wait for a new BIOS, but if not, I'll just send the motherboard back for replacement...

Yes I'm positive its the bios.

I sent them an email.......I will send another with a link to this post mentioning some ticked off consumers.......that bios should have been released a while ago......I think ddr III boards are getting higher priority atm....
