Could be, but I doubt it. In my BIOS it gives me the option to select 23, but I am not willing to run with Turbo on so my max is 20. I have a friend who can not for the life of him get his multis above 20 to be stable. It will run in windows at say 22 or 23, but once he hits it with IBT it instantly drops to 12, lol... sucks. I have a rampage III so maybe it would work on mine just fine, but like I said I don't need it. I couldn't be any happier at 4ghz and only 1.18v core.

Well 23 is the turbo multi. So that is why you cant select that multi for all 6 cores.. Now I was able to select 22 multi with no issues. I even used c-state etc while running it.

This was on an Asus Rampage III Gene with the latest bios.

 

[Zoson]

As I mentioned earlier if you have C1E enabled(C states) you cannot use your turbo multiplier. You must disable C1E and speedstep to use the turbo multiplier like a regular one. This trick is from the original i7 920 days where they were using it to get the 21x multiplier so they could do 4.2GHz with 200BCLK on the cheapest CPU available.

Thanks for the props.

The unemployment status wasn't something I was counting on happening so soon. When I first got this and my 930 I planned on beating it up a bit, did 4.5 for a while, well until I had no job and then dropped it down to 4ghz. It ran like that until late last year when I dropped it down further for safety sake. Then I replaced the 930 with this Xeon and wow, it runs cooler and at much less voltage. I would have gone for the x5670 or x5675 etc, with more multis, if they were under one hundred bucks like this x5650 was. And granted I have plenty of savings in the bank, but without income I can not get myself to do irresponsible things like neglect a chip and possible kill my computer and require myself to buy more chips. I feel 100% safe, just as safe at these clocks/temps/voltages as I do at defaults. Besides, when I buy a board I am looking for high quality components like the ones on this board, something that under the right circumstances will get me many years. Funny thing is, even with high quality comes failure, this is the second R3E I am on, the first one just suddenly had the PCIe die on me when I was overclocking the video card originally. Thankfully the ROG RMA process seemed to be no questions asked and they sent me another board pretty quick. This one has been solid the entire time but with a warmer running NB. I tried to remedy the NB chip myself, but not even the best TIM remover would remove all of that yellow crap Asus puts on it (I swear you would need an acid, lol). Next time though, I am going to cover the local components with a non-conductive sealant of some kind hopefully isolating them from the surrounding die area and then put some liquid metal tim on it, lol... If only I had the inclination to purchase a full board block back when they were being manufactured I would have. I did not originally expect to have this more than a year or two max. Now I have to keep a fan, a Antec SpotCool, on high directly over the NB 24/7 just to keep it in the 50-60C range. I wanted the interior completely fan-less though, not counting exhaust/intake/radiator fans. Its the only part of my setup that I feel I failed at (that and the lack of a CPU back plate access hole), and the only fan with sound that is annoying. lol

My heavily modded TJ07

I wish my setup looked even 10% as good as yours. The fan on the NB doesn't distract me at all. Very nice job. I can also understand your unemployment concerns, I'm currently in the same situation.

its funny you mention that...on the p6tdeluxv1 was just the opposite ...it had to have all c states enabled for turbo to kick in....i don't use turbo anymore so it doesn't change anything for me now......but thats the way it is/was on the p6tdeluxv1 with the latest bios

Yeah SpeedStep was his problem, he said he is not willing to run without it, so that means 22 is his max multi (?) and he was not aware of that. If 22 is not one of the standard x5650's Turbo multis why does Intel list 20 as the max multiplier? You have normal multis from 12-20 and then Turbo multis from 21-23, right or wrong? If I can easily change my multi to 22 and still run all 6 cores with HT on, then I think Intel should be advertising that as the max multi.

Oh wait, Zoson I just re-read your statement above in bold. So, with C1E and SpeedStep disabled, 21, 22 and 23 all become normal multipliers? In other words I should be able to run all 6 cores with HT on, so long I enable Turbo mode? I see many people who can't get 23 to run on all 6 cores, they seem to drop down to 2 cores only or the chip spontaneously drops to the lowest possible multi. lol

I guess when I find time I am going to play around with it so I can see what happens. I already have a profile saved for this setup anyway.

SpeedStep and C1E in conjunction control both power saving and turbo clocking by increasing or lowering CPU voltage and multiplier based on system load.

C1E enables dynamic C-States - Transitioning between various voltage states on the fly.
Speedstep enables the ability for the processor to select different clock multipliers on the fly.

Disabling C1E will prevent the random crashes due to a change in voltage state in response to CPU loading conditions.

Disabling Speedstep *should* give you the ability to treat the Turbo multiplier like a regular multiplier. It should also make any 'turbo' mode options in your bios disappear or grey out as they will no longer do anything.

Also lets be real clear here. There's no such thing as limited core clockspeeds on first gen i7's. It's all cores or no cores. Anyone telling you they could reach 23x multiplier on 2 cores and it would drop down on more cores is telling you lies. That's not how first gen turbo works. All your cores always go up and down in multiplier TOGETHER.

not calling anyone a lier...but my last 5639 would turbo on 2 cores only IF c states was on....i could see this happening with the osd from afterburner...just saying...now games like bf4 it would not turbo...but older games like stalker it would...i could also force it to happen to set inel burn test to use 2 cores only...and sure enough it would turbo to next multiplier (your board would already be using that multiplier though)

edit: now if you were referring to the old 920 series....you could be correct....cause i don't remember checking much in those days

You were only *USING* two cores. ALL your cores are turboing. The difference is 2nd gen and up can run different multipliers on different cores. So two cores can be running boosted while the others arn't. This is fact and not up for debate.

I was really only trying to commit on this statement....and it more than possible i misunderstood on what you meant by this....on this motherboard with c-states and the power saving stuff on (not speed step) that if i ran an application that only pushed 2 cores that they would reach 4ghz with my 5639 and the other 4 cores would stay at 3200mhz only as to how and why who knows....i always assumed it was the way turbo was designed to work mainly cause the bios was written to work that way do to power limits? idk....
only beneficial for older applications and or games that only used 2 cores....its possible i was confusing turbo with something else.....but on my board with this bios....i can run 2 of the 6 cores on a faster multiplier If i have all the c states turned on to default and just stress 2 of the cores....if it stress all of them it of course they all stay at the same lower multiplier
i have zero use for it now since i can barley use the non turbo multis lol but if i was back with the 5639 then i found the turbo to be useful in games like stalker....otherwise i would never hit 4ghz....except like you said setting IBT to use only 2 cores....and those 2 cores would jump to 4ghz

just sharing my experience...not trying to argue by any means....i could show you the same thing on this chip if you wanted

 

[Zoson]

Enough, you seem to have all sorts of totally wrong ideas. You need to actually read up on your cpu and its behavior before posting stuff like this because you're giving bad information to people.

http://www.intel.com/support/processors/corei7/sb/CS-032279.htm
"Previous Generation Intel® Core™ i7 Desktop Processors"

You'll note it says "active cores" and then gives the turbo speed. It has NOTHING to do with individual cores running at different speeds. If you use 1 or 2 cores active, you can go up two bin multipliers. if you're using more than 2, you only get one multiplier bin up. The thing is ALL your cores speed up on first gen core architecture. So even though you're only using 2 cores, all six go up to the higher clockspeed. I feel like a broken record since this is basically exactly what I said before.

Unlike you, I won't say things unless I can prove it. You might want to take that road instead of just making wild guesses.

 

[primetime]

I only made statements on how it behaves on mine...where you get wild guess from? believe what you want i don't care...really i don't

This is the way it behaves on mine....is this not turbo working?

Using all threads turbo turns off?

fuck if i know?.....i only see what its doing

 

[Zoson]

Whatever software that is, it's detecting incorrectly. Probably was made for 2nd gen+ and doesn't actually detect individual core multipliers, but rather uses an algorithm to guess which cores are clocking up. It's actually pretty obvious that this software is guessing as your first and last cores are on the same multiplier and bus speed but are supposedly running at two different clockspeeds.

Simple fact of the matter is there are only two clock domains inside 1st gen Core architecture cpus, core and uncore - which we already went over. This is changed in 2nd gen and up, and if you look at the bios controls of the high end overclocker boards, you can change the multiplier per core.

Edit: here's an example, just scroll to the bottom and look at the Turbo section:

well yes they are? which one grabbed your interest the most? the 5640 at 90 each was the best value last time i looked.......for max overclock the 5670 is a good choice but at least twice the cost(was more for me) but some got them pretty cheap....some people are just ebay marksman at getting good deals.....so what is your budget?

 

[r00k]

are those CPUs still available?

Found 4 L5639's for ~100 shipped...

L5640 for $79.99 shipped

 

[msbbc833]

What is the difference between the L series and the X series? Example: L5640 vs X5650? They are roughly the same price and clock speed, same cache, etc.

Also, what is the best x58 motherboard to use with these processors? Trying to hit 4ghz+

X5650 has a higher multiplier, but not by much really...as far as the best motherboard, if money were no issue my vote would be ASUS Rampage III Formula Republic of Gamers, LGA 1366
I don't think there's any better for 1366 boards.....My p6tdelux v1 works fine but the rampage can and will overclock a bit higher, but with that being said all the asus boards seems to do quite well. This thread has been going for quite some time, and i can't recall any asus users having issues, unlike some of the others including but not limited to evga boards in particular....the only catch is youl need the latest bios for the boards...and this could be an issue if you don't have an older cpu, so you can make sure it has the updated bios. In worse case scenario an [h] member can hook you up with a loaner 920 if needed

If you can catch a good deal go for the x5650 then 4ghz or above should be easy to achieve......Not to mention there are some real experts here with that same board in case you need assistance best of luck! i figure in a couple years time the time could be right to rebuild an 8 core xeon system on the cheap, and at the same time double our cpu power vs. doing a newer side grade for much more money. this is a real fact....even the newest amd 8 core heavily overclocked cpu still cant compete with what were using...this system is and shall be the longest best system i have ever have the pleasure of owning. Not one single regret, not one

 

[SkOrPn]

Anyone know why the R3E will not let me select 21 or 23 multi on my x5650? Gosh I hope this was not answered already. When I type in 21 it automatically puts in 22, and when I type in 23 it does the same. When I type in say 20 or 19 etc it just puts that multi in there as it should do, but not 21 or 23. I have a friend with a R3F and it does the exact same thing with the same x5650 chip. C1E and Speedstep are disabled, full LLC is enabled, and all spread spectrums are disabled as well.

What does this mean?

EDIT: Never mind me, it seems the 5650 does not allow odd number multipliers above it advertised specs, and the 5660 does not allow even numbered multis above its advertised specs. If anyone has a 23 multi on their x5650 please let me know what you did to get it to work. I've tried every setting I can think of but 23 multi is not available on my R3E and I already verified this with several other users of Rampage mobos. Why is this happening?

 

[SkOrPn]

This system is and shall be the longest best system i have ever have the pleasure of owning. Not one single regret, not one

I agree completely. However, if I was wealthy I still would not be on this system, it would probably be my media server, lol. But without the wealth, this is by far the longest running system I think I have ever owned. What I think is happening is that for the past 20 years or more systems just did not do things as fast as the human needed them to perform at, and thus we were not satisfied until x58 and 1366 came along. C2D started to give me that feeling like I was getting somewhere finally but it still did not satisfy the need for speed. This however, is snappy, maybe not instant as of yet but still VERY close, close enough to hold onto longer than usual. But, again I think it won't be until Skylake that I may be satisfied. This is actually bad news for the computer industry because I think many people upgrade just for faster equipment, not because they need it. And if that is the case with the way the economy is turning out, as these computers get faster sales will go down. Case in point, between 1995 and about 2010 I built and rebuilt my system anywhere from 2 to 5 times in a single year. NEVER have I had a single system as long as this R3E, NEVER. It is the sheer speed, my ability to tinker and tweak my OS's, and overclock the system and FINALLY throw some solid state at it that is finally getting me to a satisfied level, not to mention that money has become much more valuable to hold onto these days for more important needs.

If I can never afford to upgrade again I could easily be happy with this R3E until it dies on me. Now the GPU and Monitor is another story all together, lol...

it only goes so high and yours is doing as it should......a 5670 only does 22 or 23 for turbo only.....but mine is not 100% stable above 21 anyway...could be luck of the draw...more likely just reaching the limit of the westmere in general in my opinion....but yea 23 multi for a 5650 is never going to happen

OK, thanks primetime, I was wondering what the heck was going on. I was told, at least I thought that was what I read, that above 20 (21-23) was turbo multis only and that the only way to enable them (or get them to stick) was to disable EIST and C1E.

I will see what I can do with the 22. Thanks

 

[primetime]

So how is your current setup working out for you? clock speed, memory speed, temps performance that kind of thing....only recent change i have made was putting memory in 1t instead of default 2t.....still passes any and all stability test and gave me a slight boost in benchmarks. I actually have all power saving enabled....c states, speed step, core parking...basically any and all i could find

Not sure were you live but in North America its peak of summer so any and all measure of reducing temps from the pc the better.....course in the winter it will actually help heat a small room lol

Truth be told the performance loss of all the power savings is so minimal in my testing it was silly not to use them.....course every board is a little different in that regard

Bottom line is so many people cant get it thru there head that this cpu/x58 platform still 6 years latter outperforms any and all new cpus except the intel i7 hexacore or above ones....this system has been and still is a tank

 

[SkOrPn]

Sorry for the lack of updates, but I simply forgot. I did manage to boot into Windows at 22x205, but about three minutes into IBT it crapped out on me. Since I was at 1.35v on both qpi and cpu vcore, I was not will to raise voltage. Dropped down to 200x22 and it completed three 10 run passes of IBT on very high and 24 hours of Prime95. However, as I tried to lower voltage it immediately became unstable, so I dropped bclk some more because I prefer less heat coming from my chip. I noticed that dropping BCLK all the way down to 185 did not lose any Gflops performance, in fact it gained a tiny amount. Now I am at 185x22, 4080 mhz using only 1.30v. Not sure but I think it might go lower on the voltage. Running very nicely and snappier using the higher multi for sure.

I think I found my 24/7 for now.

Thats good to hear...heck 200 mhz wont help really in day to day stuff anyway, and depending on where you live its peak of summer...so the extra heat is not wanted or needed.

My point exactly, I just wanted to see it so I could laugh at such a club, lol...

Exactly, there is more good info on these cpus on teh interwebs too. I generally suggest people buying x58 hex core setups and then spending their perceived savings on the gpu.

Yeah $70 for a 5650 and I'm trying to ebay a pair of 7950's for $200. Value at its finest.

Where is this Intel x58 club you speak of? I went to Intels website and see no such club. Link please?

Yeah like below I meant the Intel sub forum linked below

Here.

^^

Thanks, but he said a club over at Intel site. That is the x58 club here at [H], lol. But I see now what he meant. Thanks

I'll say it again until this week I never even thought about upgrades. Then I say primetime's thread read up on the xeon's and while cruising ebay saw the fire sale on AMD video cards. If the seller will accept my offer I'll be back in the game 4Ghz+ Hexa and Crossfire 7950's not bad for less than $300. I'm 90% sure my HX 850 will be up to the task especially since the xeon will draw less juice than my i7

The low voltage and temps were the very first thing I noticed. But I'm on top tier water cooling and fantastic tim. My 930 never hardly went below 40c, unless it was dead of winter and my window was open. Although my 930 ran just fine at 1.26v @ 4ghz, it did not do so at these temps. My x5650 runs at LEAST 10C cooler at the same clock and voltages. Love it...

Agreed. My Xeon 5650 runs cooler at 4.4Ghz than my i7 920 D0 ran 4GHz

The 6 core cpus are 32nm and the 4 core cpus are 45nm. Thus the reduction in voltage, reduction in temps, and reduction in ability to tolerate higher voltages.

Well, I fried my L5639 the other night... 20 years in the industry and that's the 1st CPU I've seen die! Windows 8 just bluescreened on me and the box wouldn't post anymore. Swapped everything but the CPU in testing. finally decided to try that, and using the old 920 I got from someone in this thread she popped up. But, of course that was after I bought a 2600k + board from the F/S forum. I did get 10 months of almost double the stock vCore and at 4Ghz on it though!

wow.......thanks for posting....what was the voltages you used so the rest of us know not to venture that far out of the safe area

1. was these any signs of instability before she died? there's a hole bunch of us that would really like to hear it was going unstable for quite a while forcing you to keep upping the voltage before she died......or was it the opposite with all going fine until that dreaded bad cpu bios sound?

please be as thorough as possible with temps, voltages, how it was used and what else comes to mind......might help save another cpu with this information and as always very sorry for your loss

I did have a few random BSOD reboots during gaming. Honestly, as fast as it rebooted, I never checked into it and always assumed my video card, guess I know different now. The 2600k (stock speed for now) Asus P8P67Pro that I replaced it with from the F/S forum feels just as snappy but is definitely smoother. The old proc would ocassionally have random pauses for a sec or 2 and then fly though all the stacked up commands. I was able to transfer the windows install right over and boot right up, so I don't believe that the pauses were anything but O/C related.

My final settings were as follows:
Mult: auto
BCLK: 200
Speedstep On
All CStates on
Ended up @ 3.6Ghz base clock and 4Ghz Turbo.

CPU voltage: 1.37
PLL voltage: 2.15
QPI voltage: 1.4
I was using a CM Hyper212 and my idle temps were 98F and in-game stressed were high 145F-149F. Being a network consultant, My main usage was typical office program stuff with frequent gaming. Having it to do over again, I think I'd have backed it down to 190 BCLK and tune to voltage down as well.
