Is anyone here successfully running the Xeon L5639 on their SR2? I'm having cold boot problems with the board and was told it is most likely my ES (A0 rev) chip. Once I get the board to boot, it runs fantastic. Also if you're running the L5639's, how are your overclocks on them? What about PPD?

Specs...

SR2 mobo.
1200w PC Power and Cooling PSU
12GB G.Skill DDR3 (3x4) 1600mhz 1.5v 9-9-9-24
Corsair H80 cooler.
Radeon 2900XT video card (for testing only, going to put a Radeon 4350 in it for low power use).
Rosewill Blackhawk Ultra case.
 
I have a pair of non-ES SLBZJ running on an SR2 without issue for 13 months non-stop. If memory serves me correct, they at at 3.6Mhz and a P6904 gets 192K PPD with a 37 minute TPF.
 
I have the same chips, no issue on my sr2, ill post the other information when I get home
 
I ran the pair that W.Feather now has (innocent cpu's become such whores around here...), they are A0 and were folding stable up to 206 blk. I ended up sticking with 200 blk because SR-2's behave like strung out junkies when you take them over 200 blk.

Are the L5639s limited to 3200mhz (16x200 blk)? I'm asking because this is the first Intel system I've owned in over 10 to 15 years. Is there anyway to raise the multiplier on an ES chip? Thanks for the help guys. :)
 
Not on an sr-2, but i ran my 1 l5639 es at 205 x16 on my ud3r, for 3300, could get it stable at 210 though and keep it cool.
 
For OP: I forgot to get the info last night when i got home, here is the info I remembe roff the top of my head:

OC: 3.2/3.3 GHz, (195x17, dont remember the number), 6x 4GB G.Skill RipJaw X 1600 8-8-8 @ 1600 I think..., 1TB WD black, both cooled by True Spirits with a single AP-15 on each cooler at full speed.

OS - Kubuntu 11.10, Latest Kernal with BFS, and the Kraken

On 6903/6904 it is pulling on average ~168-175k PPD, depends on unit. SMP it pulled ~80k PPD i *think* --- I kinda forgot that part

Keep turbo engaged and you will get 17x under load for an effective 3.4ghz. One advantage of this relatively low speed is that it resides well within the lower voltage range of Intel's 32nm process. I think I ran the chips with just 1.25 vcore, 1.35vtt, and the mobo at 1.35 ioh (this will vary board to board for what's required to hit 200blk).

ES chips are only 15/16 turbo

No, it is well established that l5639 es chips do 17x turbo and l5640 es chips do 18x turbo. Dozens of us have run these configurations, its not even a question.
 
I can confirm that my A0 stepping has a 17x multiplier. You just need to enable Intel Turbo Technology in the BIOS on the SR2. :) Just found that out today after reading the posts here.
 
32nm A0 ES chips are some of the better overclocking chips as well..
 
The chips run nicely at1.25v, i need to play with em if i get time to try going lower .... if only i can hit 200 blk ....

Have you tried going for 200 blk yet? I only tried briefly without success. You may have better luck.
 
not yet, been busy with the first week of school, and other stuff popping up. if anything ill play with it to see, and then settle at a lower power draw setup / heat setup
 


Going to try for 200 Bclk tonight. System runs rock stable right now at current settings. When I go up the extra 10 mhz Bclk, should I be worried about the QPI link speed?

Set it to 4.8 (I think, you want the lowest one) and I typically set uncore multi to 18x.

You should have the memory strap at 1066 (assuming 1600 ram) and the mch strap to 1600 (this loosens up some chipset timings to allow the higher blk). You need to manually set dram timings after changing the mch strap.

As you have 190 stable, I would suspect that at most you may have to bump ioh and maybe vtt. 1.35-1.375 on ioh seems to get it done for most boards without all dimm slots populated.
 
Hi, i just received tow l5639 but every time I try to boot to windows I got a BSOD wit the BCCode 124.
Doesn't matter if I overclock the chips or run them at default:confused:
Could anybody post the exact BIOS settings?
I don't know what I'm doing wrong...
 
You need to make sure you're running the correct settings.

I had a bitch of a time getting mine to boot at any overclock. I read the SR-2 thread 5 times, before i finally got things going.

Currently running at 185 x17 on spicey l5639s at upper 50's, low 60's.

I would manually set your ram voltages, and run the 1066 memory setting. it sets things 2:8, and i strapped to 1333, my memorys 1600Cl9.

You are going to need more Vcore than you think. In my ud3r my cpu hit 205 blk at 1.2 ish Vcore, but I'm running 1.33 to get 185 blk

I'm aso on BIOS A56 btw.
 
one CPU runs all fine but looks like one is "broken". Only got those issue with the one CPU, doesn't matters if run those CPU alone or in pair. the other runs alone fine.
also the board runs fine with my e5520 ( overclock and non overclock ) as well as with a pair for x5560.
 
I had odd memory issues on mine until I put the Volts to itand played with my memory.
 
@W.Feather all Pins are fine..
Doesn't matter if I put the bad CPU in socket 0 / 1.
If I run the other CPU alone in socket 0/1 everything is fine - if I run the bad CPU alone in socket 0/1 lots of BSODs :(

Definitely sounds like a bad CPU. Replace it and move on....
