DFI LP UT X58-T3EH8 - First bench, bios screens etc

[eva2000]

I need some help. I think I am stuck at BCLK of 200. Anything higher just freezes and resets the system. Here are my settings:

cpu feature: VR enabled, Thermal disabled, CxE C1E, Execute disable Bit enabled, VT enabled, HT enabled, All cores
ram: rated timings. 2:6, so its running slower than rated.
voltages: vcore 1.3 (tried upto 1.35), vid special add enabled, special add Auto, vdroop disabled, dram 1.65, vtt 1.36 (tried upto 1.45), VTT special add Auto, CPU pll 1.8 (tried upto 1.9), IOH/ICH 1.11 (tried upto 1.31), IOH analog voltage 1.1 (tried upto 1.15). Rest default.
PPM enabled.
Turbo enabled.
BCLK 202
PCIE 100
DRAM Freq BCLK*6 (1212)
UnCore Freq BCLK*14.

Rest default.

Any ideas what's up? The CPU is definitely capable because I was running 4.32Ghz (21x206) on Asus with the same hardware. I was using 1.35Vcore, 1.38VTT, 1.3IOH, 1.84PLL for 4.32Ghz.

Again re-read links posted at http://www.xtremesystems.org/forums/...postcount=1106 has all you ever need - besides me holding your hand j/k

From 2nd link posted at http://www.xtremesystems.org/forums/...postcount=1106 you can see why you're having problems as optimal/stable Uncore to DRAM frequency ratio needs to be 2:1 so Uncore multi needs to be 2x DRAM multi, so 6x mem multi needs uncore multi at 12x and not 14x. This is also mentioned in first link thread at http://www.xtremesystems.org/forums/...postcount=1106 under tip #24 http://i4memory.com/102537-post3.html

As to the rest, will depend on what your particular cpu's bclk to cpu vtt ratio relationship is like - #2 and #3 http://i4memory.com/102537-post3.html.


My latest result, no probs pushing higher for me on 21x with W3520 now after working around 12x fixed turbo issue which seems to only effect my W3520 but not my 4x i7 920 cpus. i7 Turbo says max Calculated and MSR multi is 21x under load and 3dmark06 cpu score confirms it is working at 21x210Bclk with VID = AUTO + VID Special Add = 110.1% for 1.088v idle and 1.312v load vcore when CxE set to C1E.

CPUZ Idle vs After Load Idle

max Calculated and MSR multi is 21x



3dmark06

max Calculated and MSR multi is 21x
