@Dino: any memory clocking data for this board? I am having some trouble getting stable runs on c7 @ 2160Mhz. The RAM (OCZ Blades) and processor (980x) are capable on doing this on the UD9 and R3E. I dunno what's the big difference for the X58A-OC board. Thanks in advance...

F5b bios, btw....

I was that F5B isn't overvolting as much as the previous BIOSes, are you by chance compensating for the overvolt or reading by DMM?

And Miravo I feel for you man, after you told me the situation, i am sorry for your pain. lol such an odd situation.

@sin: yup, the vdimm was 0.02 less in the DMM from what is set in the bios. DMM reading is at 1.78vdimm and I have it at 1.80v in the bios.

[dinos22]

last time i seriously benched ram clocked alright

@dino: thanks for that. Let me try that bios. I have tried F5b and F4c.

My board suddenly became very unstable. I can't even boot into windows with settings which were prime/LinX stable. Clear CMOS is next... Never had this many problems with the eVGA Classified board...

hey man what about qpi/vtt?

[maxxx]

hey man what about qpi/vtt?

@sin: QPI/VTT were at the correct settings I think. Was playing from 1.38v to 1.47v (DMM read). I am going try again tonight. Ok, I am not on extreme cold. Just on water cooling. Temps are still manageable.

Hey guys!

For all the subscribers - Check out my Bclk update on the OC board - 268+ Bclk!!

http://www.xtremesystems.org/forums/...apon-Of-Choice!

[Lsdmeasap]

Just smashed the world record for 1366 Bclk!!

http://www.xtremesystems.org/forums/...=1#post4900521

here's a sneak peak (IE Not my highest)! Also made a video booting at 260 and then going up to 275 in windows

Current X58 HWBot records

I'll make a WR thread tomorrow with my highest result, going for 3Ghz memory action tonight on X58

[donmarkoni]

Amazing!

Congrats.

[Lsdmeasap]

Thanks man, this board has been so much fun!!

Bclk World Record secured!

Finally came to it, to rebuild my test/game-rig.
Replaced my Rex3 with the OC.

F****ckd up almost a whole weekend testing and figuring out how the damned thing works.
Regardles any manual setting in the bios, it keeps crashing going over 3,7Ghz, or above 1630 7-8-7-24 using 24Gb`s.

Using the 4 Ghz button, made it boot, @ 25x160. From there went up to 167FSB, with manual set timings, and it`s al LiX stable.

Now figuring out to get 23x180+ 7-8-7-24

take the cooler off and clean your CPU pads and dont tighten too much when you remount

after clearing defaults only change bclock, multi and volts, say 200x20 and then start tweaking from there and see what is causing the low bclock as it obviously isnt normal

Hi Dino,
I think you are lost somewhere arround Adriatic Sea.

Hi Dino,

Current setup:
W3680 3005-F-553 @4.2 -1,25V
X58A-OC
Geil Ultra+ 6x4GB 7-8-7-24
NH-D14 Triple fan
POV 480 Sli

Will give it another go tonight, and reseat everything.
Compared to UD7-r1, the voltages set by default are much higher, using the 4Ghz button. DMM difference is almost 0,05V(1,254V-UD7 / 1,321-OC)

[Hondacity]

that should be 0.050v not 500mv

[XII]

Reseated the whole shabam, , still a 25x160 on the 4Ghz button. (Print of the paste on the cooler and core near perfect)
Memory reseated, etc. Let the paste cure for 2 hours, and started to work the other way around.

12 BSOD`s and a lot of cursing later, succes.
Voltages are way above previous needed settings, but starting to get somewhere.
Temps are 4-8 degrees up, but still within my limits.

During the short tests, using LinX for a couple of rounds, there is still improvement possible as Gflops are still going up, with every few mHz up.

I think your problem with Low bclk and high voltage needed is because your trying to push 12gb of ram. Drop that down to 6gb or lower and see what you can do. If you need all that ram, then that is what you get and why you need 1.5v for qpi/vtt at only 180 bclk

Well, actually trying to push 24Gb of ram.
Know it is crazy, but heck, if it fits, why not push it to it`s limits.
It runs stable @ 1866 7-8-7 , 2000 8-9-8, 2100 9-9-9.
Big problem is, getting highest core icm max mem at desent timings.

Will continue..........

[XII]

Started all over again.
Nice one, and 81Gflop`s Linx.
Voltage`s within reason.

[XII]

After some testing using F3 and F4 biosses, back to F5b.

Cleared cmos a few times, reflashed, loaded defaults, reboot, manual settings, etc.

Firts run @ decent voltages:
CPU PLL - 1,6000
QPI/VTT - 1,435
Core - 1,3625
LLC - Auto
Dram - 1,64
IOH PLL - 1,22
Rest on auto

[sin0822]

yea it seems F5B is the best

[Hondacity]

24gb

[XII]

1600+ on 24 Gb keeps demanding 1,51V on Qpi/Vtt, and results in coretemps of +75C.
(1,35V on Rex3 for 1800 7-8-7, 1,4V on Classie for 1780 7-8-7, 1,325 on UD7r1 for 1800 7-8-7)

The only one capable running 6-6-5-21-72 @1370, 31X137 @ 1,325V is the X58A-OC, resulting in a nice 87 GFlops.
82GFlops @+ 1600 7-8-7 @ voltage N.U.T.S.
84Gglops @ 1800 7-8-7 on Rex3

For the current I`ll keep tuning

[XII]

Have kicked in some Gskill Hypers, but results aren`t as hoped.

Linx and prime stable, but even one Mhz more results in a crash.
http://valid.canardpc.com/show_oc.php?id=1972947

If using Easytune, still defaults @~3600 143x25 with Qpi@1,51
If a reboot occurs after a bluescreen, HT is reset to enabled

Hoping for a bios, that fixes things for 6 sticks - 6x Hypers max out ~1850 with Qpi ~1,55

Might be core or combo related, but `m not impressed so far.

EDIT.

Some more testing done.
210X21 stable on air. Highest done on this core.
Timings had to drop to 8-8-8-21-1T though.
Uncore running @X1,5 and HT off.
Highest core speed on air so far.
Mem still sucks though.
Next runs, with 3x 4Gb - Gskill BFR and Ultra+
Something should work
