ok now this is very strange ....i have e5645 not e5620 as shown in the cpuz screen shot what gives-
 
bios shows e5645 i know i have them --why is cpuz reporting a wrong processor model
 

i have a test with similar settings so you can compare  

those are some nice scores  ,,, strange that with stock gpu u have this score ---??? ..
 
ur gpus are all on stock ..
 
 

so u eman to say 2 -mars 2 edition at stock beast 4 gtx-580 over clocked --
 
this is strange indeed --or maybe they are that powerfull .
 
 

the score u posted above --is that with stock setings --coz i have oc the gpus to 920 on the core to get that score --- , that is what i was saying .
 
also i guess u are on a xtreme cpu at 4ghz where as i am not at 4ghz and on non xtreme xeons .
 
anyway nice score ---even if on stock .
can  y post a pic of ur rig / set up ./ mobo etc
 

brother how do i submit my scores to them ..can u help i have no idea
 
 

massive .....very nice .....love those gpus ...wowwwww
 
 

yeah thanks bro .! looking forward for ur build .
 

no more things to do, purchase higher multiplier xeons, you will reach 4.8 at maximum with tons of luck.

consider yourself lucky. I have not seen you complain about lost ram. My SR2 with my 5645's lose ram at anything above 182 for some reason. I had it at 200 at one time, not sure what happened. haven't looked into it much though.
 
My sr2 with 5670's is not so bad but will do the same thing. I cannot use turbo with my 5670's for some reason, it will crash even at low clocks. Could be slightly defective mobo's, not sure.
 
I currently run my 5645s [link=mailto:19*182@1.247v]19*182@1.247v[/link] I could probably run lower volts, just haven't played with it much cause I need the system running 24-7
 
My 5670's are running [link=mailto:22*186@1.35v]22*186@1.35v[/link] Same thing, I can tweak more and/or run lower volts, just haven't played with it much
 
I think the 5645's ideal speed is typically 3.8ghz. higher will take more work and might not be as stable.
 
Best of luck, but if you want to run in the mid 4ghz range, you need different chips

how many cores should i drop ---for the 21 multi --
 
so with a 21 multi can i get 4.5ghz .or more ---this is exciting i never knew this --thanks -
 
appreciate some more information on this
 

muhd86

so u did 2 cores - 4 threads , 21 multi at 1.424 volts
wow ---


so can u do more then 2 cores e.g 4 cores 8 threads

Turbo frequency
2800 MHz (1 or 2 cores) 21x 2 cores 4 threads
2667 MHz (3 or 4 cores) 20x 4 cores 8 threads
2533 MHz (5 or 6 cores) 19x 6 cores 12 threads
Edit: added thread count to original post
Or you can run odd number of cores/threads.
Like 3 cores 6 threads.

I set manual the multi but disable the C states with turbo enabled.
If you drop to only 1/2 cores then 21x will become available 20x will be able to be picked when dropped to 3/4 cores.

a dry run ...
 

Darn .. for some reason .. I can't get my e5649 runs above 170x19.  System would crash  while testing with OCCT right away.
