Well the fact that its total cache is 8MB on top of that it is DDR3 on top of that its AM3 and if it was 2.4Ghz "Really" it would have already launched as a part of the PhII 8xx range.
Also the voltage seems to be very good for a low end 2.4Ghz part.

O yah but he knows I used that on 939, most of the time I was on phase or water though, the TTBT just binned all my chips.
Here's the same ES chip stock volts as you seemed curious. Max mine could prime without touching any voltage.

'Phenom II X4 955' sample surfaces, is overclocked to 4GHz
Dumo from the XtremeSystems Forums shows the 955 engineering sample running at the stock 3.2GHz speed with a 1.25V voltage setting. At 1.45V with air cooling, the poster claims he was able to hit a cool 4GHz by pushing the HyperTransport speed from 200 to 250MHz—and he even has a screenshot to prove it. That screenshot shows Dumo also overclocked his memory to 1666MHz, which netted over 11GB/s of read bandwidth according to a Lavalys Everest benchmark.
The Phenom II X4 955 exists, and it's a pretty nice overclocker. At least, that's the impression you might get after reading a thread at the XtremeSystems Forums, in which a member has posted CPU-Z screenshots of the unannounced AMD processor running overclocked in the Windows 7 beta.
As you might remember, we last wrote about this purported Phenom II X4 955 two weeks ago. Back then, word was that the 3.2GHz quad-core CPU would hit stores in April, and that it would be a Socket AM3 part with a 125W thermal envelope and support for DDR3-1333 memory. That chip was also said to be a replacement for a 3.1GHz Phenom II X4 950, which AMD supposedly canceled because of better-than-expected yields.

I also agree. The CPU market sucks now a days in retail at least. AMD has its canon's placed in the dead center market there is where most money is anyways. Most people tend to buy a affordable processor with performance rather than only performance. Also on top of these OEM's also seems to like the PhII so that can only mean good things for the old green. :D
I really don't know what people do buying processors like the i965, etc. If you are a enthuse you should be able to OC a i920 to reach near i965 performance. Not only Intel even some highly priced AMD FX processors were similar in the "who gives a crap about money" category :shakes: .

Either I'm very unlucky or doing something wrong. I've tested at least 10 940's and none of them could do 3.6ghz with stock Vcore. Does having all memory slot occupied (total 8Gb) affect the overclockability?

940 BE has a high multi, 720 be has a high multi.....all es chips have unlocked multis........even chips that were destined to be LE 1200's....
I have a couple of ES chips "floating around" here: My 3 B0 Phenom/Barcelona I ES's run at 1.6GHz... I wish they were unlocked, the way they perform at stock an OC'ed 9850BE would beat both Barcelonas in a socket F mobo:p: Same with my X2 4600+ socket 939 ES. Not unlocked, but it's no doubt an ES. I also have a socket 940 ES, and old Sledgehammer. 2Ghz stock, not unlocked. Ah... and the 2 socket 754 ES's... 9 and 10 multi, and nothing more. I have an FX57 ES and a Phenom 9900 ES. Both unlocked, but that's not so shocking I think.;)
I'm curious about the "part number" of this 945 ES. It's pretty straight forward to find out the stock speed then.:) Which will help us deciding what PN it may have when it's released as a retail chip.

I bought an AM3 board and 720be to set up so when the faster 4 cores arrive I'll be ready to drop one in.
Bought a 2nd hand 939pin X2 3800 a year or so ago and kinda remember seeing an ES in CPUZ. Remember 1 core running warmer than the other. Guy probably sold me one that "dropped of the truck".

Since you are running 8GBs of memory, one would assume you are also running XP/Vista 64. If that is the case, the 64-bit OS actually makes a huge difference in your clock rates and voltages. Clock rates will be down compared to Vista 32/XP Pro SP3 while voltages will need to be increased to improve stability at like clock rates.

All AM3 chips have working IMC's for DDR2 or DDR3, depending on the mobo you put them in. I'm not sure, but I don't think you can mix the memory (even if the board has slots for both). Pretty sure it has to be one or the other...

For what it's worth BroE, Fudzilla says we can expect new chips in April. Although it doesn't particulary mention the 945 it does say to expect chips in the 3.1Ghz range.
It's Fudzilla, so take it with a grain of salt, but it sounds like we will see some new chips next month. :D

Dumo, I'm tackling something today so i'm busy but tommorow I'm going to see if I can whip up a decent mounting kit for our old phase units.
Very curious what the 720's can do under mach 1's :)

But if it dead center then NB clocking will be a breeze

Dumo, how much can u get with 1.55V on AIR? 1.45V on AIR is nice, but its stable? And i hope for 4200 with 1.55V :)...I think the new 955 will overclock better than this ES. If you want to run >4.1Ghz then the best way is to go water cooling or Single Stage phase.
Any X4 cpu on air cooling will suffer from heat @ 4.1Ghz and thats not good.

Dumo,
I am a professional musician using a PC for streaming audio for sampled instruments to mix with my synthesizers.
I love the way the AMD 770 board from Gigabyte looks and I am upgrading to that instead of the i7. I just don't need 2,3 or 4 PCI-e 16X slots.
I am confused on which RAM I should get.
I need to use the optimal speed for my apps which is 1800MHz.
I see you are deep into this as I am in my synthesizers.
I will only need to OC the system far enough to get the RAM ti a stable 1800MHz.
I will be using 4 x 2GB DIMM's.
I would really appreciate any help from you on this matter.
Thanks.
BTW, your help will keep the dance floors of the clubs in Vegas filled......:up:

Dumo,
I am a professional musician using a PC for streaming audio for sampled instruments to mix with my synthesizers.
I love the way the AMD 770 board from Gigabyte looks and I am upgrading to that instead of the i7. I just don't need 2,3 or 4 PCI-e 16X slots.
I am confused on which RAM I should get.

at the moment none of the amd cpus support memory speeds above 1600mhz. 1600 is hard limit ;)

For my needs 1600 Might work fine as long as the CL settings can be a stable 7 or 8.
Thanks for the insight.
BTW I will go 64bit by years end and will be using 16GB's w/ 4 x 4GB DIMM's.
Unfortunately my apps take advantage of huge RAM that sometimes can choke a desktop Mobo.
We have 100's of 1000's of buffers stored that allow us to have realtime ( low latency ) audio by triggering the first portion from RAM, then streaming the rest of the triggered notes from the HDD's.
Even though some posers claim RAID adds more polyphony or bandwidth, there really isn't a need unless you are playing 512 stereo tracks and mastering in real time.
I use a poweful 1U DSP rack full of ADP21369's for that.
Anyone who thinks CPU's are great at doing virtual synthesis should hear this.

Thanks for the help guys, I am going with the Gigabyte 770 using the PCI-e 1X and save a bundle.
It seems like the X4 955 can handle a little bit of OC'ing to get the RAM up to 1600, so I will post it's success/failure within the month.

scope4live, if you want cas 7 at 1600, get OCZ Platinum AMD Edition
if you want cas8 at 1600, get OCZ Gold AMD Edition. These two kits will guaranty you those speeds. While other ram even from same company has difficulty playing nice at 1600 and need quite some tweaking :)
besides those two are Low Voltage kits :)

CHEW, the thing is: will you be able to run your PC 24/7 at those speeds stable? You can pull whatever numbers you want for a brief moment with a bit of luck. The guy is running some kind of music factory at his place, so he needs atmost stability from his system, and he will not be running super pi on his pc ;)
and 1600 is plenty at least for me, no need on going for those crazy speeds. And I do not need to try to get to 2k, we have Tony from OCZ for that :D
But I see I forgot that this is extreme systems forum, so forgive my a bit different point of view towards PC usage ;)

You said try to hit 1800 then complain?
3 diff sets of ram aren't luck nor is 32m but whatever.
Super PI 32m is the choice for showing ram stability......15mins + not very brief.
I ;) becasue I think 2k is impossible
As far as ram for everyday Use I like my OCZ AM3 kit.

I said 1800 and 2k. My point is, amd cpu officially support 1600, everything else is luck (some people call it a skill, but whatever). That is why you do not see any kits with speed above 1600 for amd. MSI gd70 has some numbers on the box saying memory speeds 2k+ or something, but everyone in the industry are saying that you will not see these speeds, unless amd will release new revision with tweaked MC or something. Unless you want to spend couple of days getting those extra mhz and not getting the performance boost. Instead try tightening the timings while staying within the limits of the CPU memory controller.
15mins is not 24/7 of crucial work. I here not to pick up a fight, just trying to help a person who needs an advice, that's it.
In couple of days I, myself will be testing my new rig (msi gd70, ocz platinum amd edition, 955be). I will make sure to try that magic 2000mhz :D

Yah I forsee a wall at 952 or at least thats where Titon hit a wall.
1904 effective no clue.
Gigabyte seems to have a lower wall around 1880.
Honestly that OCZ kit will run 1680 24/7, after that speed all bets are off its purely for benching.
There is a performance boost if timings are good at 1800......advanced tuning of ram is the only way it will happen so its not luck. you must realize i'm tuning for 6gig sometime's, what works well at 3.6-3.8 does not necessarily ring true at 6gig +.
I tested 1500 5-5-5 and it fell flat on its face at 6 gig..... 3.6- 4.0 it shined...
My bench partner has the same sticks as me could not hit 1800 I sent him a few pointers via AIM on tweaking and he hit 1800 as well.................
The truth of it is tighter and lower is just alot easier for the same performance limited to 3.6-4.0 gig cpu speeds........
Unfortuantely as I told Tony, I must lead 2 lives.....one of the hardcore bencher the other as the 24/7 stable rig....

I have been warned to stay away from the newest Elpida stuff that OCZ uses, but my key tech informed me assuming I was going with the usual Intel design I have used since '99.
Sure I am taking a chance and this is a mission critical set up.
I do all of this in real time live and blend it with analog synthesizers of yore for a truly immense amount of GFLOPS in DSP and CPU combined.
1800 is the utopian streaming speed but after some in house tests on the 790 Gigabyte board and 8GB's of RAM, we were noticing pops and clicks since the RAM is the second stage in the sub system, so backing it down to 1333 and CAS7 using 8GB's worked flawlessley but it does steal some of the sampled instruments voices when doing the high polyphony of a Grand Piano with a symphony sized string section ( 32 violins ).
I think tonight he will push it back up to 1600 and try again.
But this is GSkill 1066 RAM at CAS 7.
I suppose a higher rated RAM like OCZ will help that out.
This sure is fun though.
After 3500 USD for a DSP soundcard the idea of an entire new DAW using the AMD 955 and 770 mobo w/ 4U atx chassis and all new parts for under 1000 USD is most refreshing.
The very first CPU I used when I started this :banana::banana::banana::banana: in'99 was 1 GHz Coppermine. The CPU alone cost me 1099 USD,..........so it's my turn to thank AMD for keeping Intel honest.
Thanks Guys.

I am very curious about that 'staying away from elpida' part. can you elaborate? All i know, that those AMD edition kits are 100% guaranty to you that they will work at advertised speeds at advertised timings. if it says 1600c7 it will work at that speed. Sure you can try other stuff from other companies and even from OCZ themselves but you will have to spend some time tweaking the memory to work at certain speeds.

My DAW buddy is a pro video archiver here in LV and has some incredibly powerful Xeons w/ RAID 3 cards and SAS drives. So he's pretty up to snuff w/ the video stuff and lets me tinker with his audio/video apps which most are streamer based.
But for his gaming box he just sent back 2 x sets of high end triple channel RAM with low latency @ 2000 that used Elpida chips whatever that is. One set being defective wouldn't have raised an eyebrow both both sets seem to be untested and sold.
Seems as though lot's of this is happening during an econmy where everyone is cutting costs. R & D cutbacks are not wise, but QC seems logical to me.
I won't ever need that RAM until developers jump into the technology and actually optimize for SSE4, etc. Audio developers are just now getting around to 64bit and core assignments on quads.
I do have one more question though if you got time.
I have always bought RAM based on the stock voltage of the motherboard.
Would I be wise to keep that in mind or go ahead and get the RAM that is advertised at 1.65v to 1.9v in hopes the AND 770 chipset & BIOS will OC to a higher stable voltage.
Sorry it's my first time doing this and my friend is only knowledgable w/ dual i7 Macs and Xeons mostly. The i7 is his first gaming rig so he still isn't up to snuff, and it's even possible the RAM troubles he is having could be a mistake on his part.
Anyways the voltage thing is still confusing me a little.
On old Intel boards we had trouble posting if the RAM voltage wasn't identical.
Thanks Brotha' Man...:cool:

as I told you before. OCZ amd edition ram will work as advertised, that is speed, timings and volts, although depending on motherboard you might need to add 0.0something volts to ram, but not more.
regarding Elpida chips, you are comparing some ram manufacturer who provides memory to apple with OCZ who are known to us as one of the best memory manufacturers and they are liked by most of us because they really deliver and their customer service is brilliant. with their ram you get lifetime warranty, and I am sure that they test their memory extensively :)

Sorry for requiring the extra assurance on the AMD choice.
And I have had OCZ Gold series before so I know they make great products.
The RAM I spoke of was 2000+ Triple Channel Kits for the gaming i7.
The Dual Xeon PC and Dual Nehalem MacPro are custom built and tweaking around with those will void the generous warranty and service provided from Avid.
He is tweaking his i7 gaming rig and is interested in water cooling, etc. Stuff I am sure is fun and rewarding but not really good for a stable 24/7 audio DAW.
The AMD DAW is going to be fun and I can't remember the last time I paid 175USD for 8GB;s of RAM.
I should actually stay in XP32 and make 2 of these w/ 4GB's and and access more RAM w/ the 3GB PAE Switch I currently use.
Thanks For The Help....

Well the advice was correctamundo.
The locally bought RAM was 30 bucks more but whats a few bucks when it comes to a mean lean audio machine.
I have just recieved a call that I can come by and test the machine.
It is running everything in 64bit right now but the RAM tip works fine according to the builder. My apps are mostly 32bit but a few are 64bit and they are working under XP64 with no troubles.
I really hope I can upgrade next year to the 4GB DIMM's for 16GB total in Windows 7.
I hate M$ but being able to assign cores efficiently is really useful for multiple audio apps.
If I feel the need to OC the 770 for extra juice I hope you guys don't mind a moron like me asking for more tips.
It seems like you guys know your hardware.
BTW how do you post a jpeg here when it asks for a URL and I only have a camera and HDD pictures?
I could show you guys how happy the 770 looks inside of a 4U ATX chassis.
I use 4 x Raptor 150's in a SATA RAID cage but only because the silence and cooling are needed, not the RAID.
Anyways thanks again and as Douglas MacArthur said............I shall return.

Well that's the beauty of AMD. If it doesn't work, the price to build another is so ridiculously cheap and powerful I will have no problem building 2 x w/ 8GB's.
But I am getting ahead of myself here. The most important app. I use for streaming is still in BETA for it's 64bit upgrade. I will upgrade by the end of summer. I don't think that I will see problems in 64bit w/ 8GB's, but 16GB's is a crapshoot. People who do what I am doing spend thousands on i7 and Dual Xeon builds.
Pro builders who design DAW's for big production facilities of course want me to spend 5 large on a DAW while they laugh about the AMD. " You're going to have crashes Live.....OMG."
They are just pissing on my back and trying to tell me that's it's raining.
5 Large for a simple streaming DAW.................that Dog Don't Hunt.
If I fail, I shall be quiet, but if this DAW works, even though the Gods tell me it won't, I should start building these for 2 grand and steal the business from these Intel/Mac elitists.
