ok.....figured i would try the lower voltage thing...had to down clock to 4000mhz.....no big deal.....passed both major stress tests no problem.....then it cant even complete hyperpi lol...WTF?

ran stupid thing twice...just fail lol...but i know its works fine at 1.4 qpi voltage....hell even at 4400mhz....kinda a head scratcher ain't it? it passes the 2 hardest stress tests at 10 runs each but fails hyperpi? that makes a lot of sense :rolleyes:

Why is your gflops so low at that clock? At the same clocks and less voltage I am hitting near 70-71 Gflops. Ok, I think your chip needs to be pawned off for another, lol...

For both IBT and LinX do not exceed 9216 MB for testing unless you disable Hyperthreading. When you have such a large memory pool it makes it possible for Linpack to thrash your cores to the point where it's no longer correctly stressing. Me and two others investigated this over at XS. We never found an instance where if you tested 9216MB LinX HT on that anything else would fail.

That is good to know... Thanks...

where you say this....you mean its better to custom set the memory test a little lower like 9000 even to avoid improper test results? I think i'm understanding you correctly :confused:

No program is the same.

I've also found IBT starts losing Gflops when you aren't completely stable but stable enough to not crash.

I get [email protected] no HT. HT might lower the score a bit. I was getting 90 when I was trying to see what the chip could do at 4Ghz+.

Just use 9216.

thanks you for that...good info to use from this point forward....i noticed your not using the newest version of Linx....i don't like it anyway...i cant figure out how to use it properly not to mention just setting it to 9216 like in your screenshot....guess i'll have to stick with intel burn test until i learn how to use that other software:(

not only that i noticed y gigaflops was really low last time i used LinX....but with IBT its fine

It's an old screenshot. You just copy the corresponding files your linx folder. Google can help, too.

what is your thoughts on doing this Zoson? http://lucca.hardforum.com/rewrite/...669&id=1&match=1&source=none&destination=none
P6T WS PRO bios might bring me some better overclocking......if you were in my spot, would you go for it?

edit: actually after further investigating...looks like they guy has to swap the bios chip every time he trys a new bios.....since the board wont let you flash another boards bios.....so not as easy as it sounds ( unless you happen to have one of those other boards) then it be easy

Could someone tell me if there's a huge difference between getting the x5650 and the x5670? I mean if I successfully overclocked these two chips to say 3.8 ghz then wouldn't they both perform the same?

Possible to get a higher overclock with lower volts on a X5670 and having access to a higher multiplier. Of course every chip is differnt.

For my X5650 I need 1.42v to hit 4.4ghz. I think Primetime hit 4.4ghz at like 1.375? Cant remember.

Either way I think you would be better off saving money and getting a X5650

I consider 1.375 to be really high as well, what oc can you achieve with say 1.3125 or 1.33 if you can remember

Again depends on the chip. Since I gave my X5650 to my girlfriend to use. I put it at 4ghz at 1.32v.

Of course you might need less volts to hit the 4ghz on a X5670.

yeah but currently on ebay I'd need 92 extra dollars to also use .3X less volts or gain maybe 400 mhz. I rather just get a 2 chips and save 4 bucks

I mean the biggest attraction to these chips were they were 100ish bucks, gonna spend around 200 ish bucks on a cpu might as well go for an es e5-2600 so you can also then ditch the ICH intel chipset x58 has to offer

Yap. Thats why I got a X5650 over a X5670. I did not see a reason to spend another $100-110 for an extra multi and maybe a chance at lower volts.

I would go with the X5650.
 
Can anyone tell me what vcore they needed to get their L5639 or L5640 3.8-4ghz? I'm really attracted to the these cpu's TDP of 60 W. Also can I use normal desktop ram for all of these cpus?

I'm hoping to use these: http://www.newegg.com/Product/Product.aspx?Item=N82E16820226329 with a desktop x58 board

1.23v for an L5639 (before I sold it) for 3.8ghz.

I bought these for my X58 setup http://www.newegg.com/Product/Product.aspx?Item=N82E16820231350

Just something to note. I think I saw a review that the L5639/40 has a lower IPC then the X5650.
 
Could someone tell me if there's a huge difference between getting the x5650 and the x5670? I mean if I successfully overclocked these two chips to say 3.8 ghz then wouldn't they both perform the same?
I'm sitting at 1.18v @ 4ghz on my x5650, so like others said it depends on the chip.
 
1.23v on a 5639 for a stable 3.8ghz? Pics or it didn't happen. :p (I just want to see your bios settings ha)
 
See the page before this!!!! LOL

you realize you have the most advanced single socket x58 motherboard ever created..and your barley pushing it...i'm just teasing you lol...very nice voltages indeed;)

Here's where I'm at today with my cheapo workstation motherboard

Droped the ram timing to 3t if your wondering why the hyperpi is so bad

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

Very fucking nice dude...me likes....there will never be the perfect build...cause something will always come up....we didn't think about before hand....for what you got...looks impressive...lots of attention to detail (makes my rig look like a tonka toy)

Has anyone tried using 24 gigs of ram in their x58 mobo with 3x8 sticks so that not all banks are used? Have they been able to OC with ram similar to this using their x5600 cpus?

I'm planning to get http://www.newegg.com/Product/Product.aspx?Item=N82E16820226329 these unless someone has a better recommendation?

I can only imagine running 3 sticks versus 6 (like mine) in tipple channel will help in some way.....but lord, I thought the prices of ram was cheaper nowadays...i would go so far as to suggest you might get 1n stable vs 2 or 3....only people who would know for sure is someone whos been threw the exact same thing....just really all guess work...but i personally feel like it would work pretty darn good

Oh on newegg they're priced at 300ish bucks, you can finder some of them for 10 bucks cheaper or so, I just choose these cause they were 1.35 volts and 1866

Still kinda expensive, but it's tolerable I guess
 
I would assume, and understand its only an assumption on my part, that since these Xeons are good up to 288GB according to Intel ARK's website, that all the X58 mobo's that can run Xeons are also good with higher capacities than originally advertised. Thus my guess is that you can run up to 48GB just fine, and certainly 3x8GB. You may need more volts, more qpi and maybe drop the uncore a bit, but it should still work. I would love to be running 48GB at least at 1600 mhz myself.

I would need to set the QPI in bios higher? The options I have go up to 6.4 gt I think? Is that what you're referring to?

No, I was reffering to the possibility of needing more QPi voltage and more ram voltage, and possibly lowering Uncore speed to 1.5x. However, I would not know first hand, as I am just guessing from some research I did months ago.
 
Oh okay lol, forgot about that volt setting, yeah all makes sense. Thanks for your help
 
here's another benchmark for you guys......just to see how we actually stand in real world application
povresults_zpsbba7e7ec.jpg

Mine scores 1956..thats well above even the newest amd 8 core running at 5ghz:D

here is a not to old of a chart of cpus by performance
povray_0_0.png
 
It'll be fine. 5650 has a max multiplier of 20. 20x200BLCK is 4000mhz. A 200 BLCK will give you 1600mhz for ram speed.
 
Anything above 20 are Turbo multis on the 5650, and that does not work without bugs on every motherboard... And its 12-23 according to my BIOS and CPU-Z. Intel advertises it as a max multiplier of 20.

Hmmm Odd. I had no issues to max out 22x200 at 4.4ghz. Did a 24 hour torcher test on all 6 cores with no issues?

Sooooo maybe it depends on the motherboard?

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.
