Nice memory clocks!
Thanks OC
(2) 3820s same batch 3201B200 with s/n XXA1356 and 1358. One wall @ 5250/2405 mem. cold and second chip (so far) boot up @ 5100/2580 air.
Bios 1103 air....will freez it next.

Can someone please help an n00b
I recently purchased a RIVE, 3930k C2 & 16Gb of mushkin 2133 Mhz
Thanks to donmarkoni information (shown below), I was able to set the board to overclock the chip to 4.5Ghz @ 1.35 volts using BIOS 1101
I tested this with prime 95 without any stability issues.
I then attempted to push the chip further by increasing the cores to 50 & upping the voltage to 1.4v to give me 5.0Ghz
My system would then boot into windows & run without any issues.
Once I run prime 95 the system would lock after a few seconds & give BSOD.
The codes I have noted are
1 - (0xFFFFF880061D7180)
2 - (0xFFFFF880062A5180)
3 - (0xFFFFF880069B3180)
I have steadily increased the voltage to 1.45volts & the system will not run prime95.
The system is being cooled by a custom water setup @ this time. So temps are not that big a problem.
Also is there a list of max voltages that SB-E will run ie. max CPU, VTT, PLL etc as I would prefer not to kill any thing just yet :shakes:
If anyone can point me in the right direction, it will be much appreciated.
Those settings are trying to run your DRAM @ 2400 with CL 7 timings. That will not work.
Also most CPUs to run 6c/12t at 5.0GHz take 1.48 - 1.52v
Thanks Kensek for the reply.
I should have added that I set the ram to the correct specification set out by muskin.
Am I better off underclocking the RAM for now until I can find the upper limit of the chip?
Yeah for SB-E it is a good idea to clock CPU, BCLK, and mem separately at first so you have an idea where each maxes out. Makes it easier in the long run.
Thanks Eldonko
Just had another go @ 5.0Ghz with the RAM set @ 1600Mhz & then 1066Mhz & I am still getting the message "clock interrupt was not received on a second processor within the allocated time intended"
What are your temps like? Keep in mind not all chips are going to do 5Ghz..
The temps are around 60C
I understand that not all chips are the same (silicon lottery) but I would like to try & get as much from it as possible.
Have you tried 125x40? There is widespread opinion, backed by theory, that lower multi requires less voltage for SB-E.
Thanks donmarkoni for the input.
I did what you suggested & used 125x40 with 1.5 volts - BSOD
Then 125x39 with 1.5 volts - BSOD
Then 125X38 with 1.45 volts & its still running prime
@ great IMC Dumo :up:
Thanks owik:)
My third 3820 turned out to be good @ least on air, hope it will scale higher with cold
looks like you got a good one Dumo:yepp:
If they can clock memory well, they tend to clock high on the core as well (at least on sb-e), I am sure it will be nice on cold, especially since your already at almost 5100:up:
I have continued testing & I run prime 95 for 8 hrs with 125x38 @1.42 volts (memory set @ 2000Mhz)
The other settings were
VTT CPU - 1.2v
2nd VTTCPU - 1.05v
CPU VCCSA - 1.221v
DRAM - 1.668v
CPU PLL - 1.881v
PCH - 1.096v
Is there something I am missing or can I push any of the other settings a little harder due to being under water (have increased CPU voltage up to 1.5v & still getting 0101 codes)
Any help will be gratefully received
Very nice chip Dumo :up:
Those are nice 24/7 settings, if nothing better is gained.
You can try 100x48 with same or slightly higher voltage to see if there is effect from higher/lower multi.
Also try playing with CPU PLL (1.25V- 2.00V), and BCLK Skew/PCIE CLK Skew -1/-10, -2/-20, +1/+5, +1/+10, +2/+10.
Could be that CPU is not such a great one.
Thanks l0ud:up:...Still wanna play with it before go cold
Thanks Viss, not too shabby for my third 3820 binned:D

Max bclk on air...

Nice Dumo! 162bclk and 2300c10 is pretty strong, cant wait to see you results on SS.
you may wanna use this to balance temps with speeds
