hi eva, have you tested vdrop with load line enable / disable ??

eva2000

Haven't tested Loadline calibration yet. Haven't had the need to move off AUTO for it for all above benchmark/results yet

very good BP P6T6 WS Rèvolution

Very nice clocks there, DDR3-2030 7-7-7-x at 1.66v!

Just bought this cpu 3rd hand, nice clocker apparently - Xeon W3540 3845B010

On Asus P6T6 WS Revolution with 0007 beta bios. Default AUTO vcore in bios reports = 1.088v. Manually need to set vcore to 1.10625v to get 1.088v vcore reported in bios.


Very promising start indeed using 4Ghz Prime95 benchmark as a guide to a cpu's potential. This Xeon W3540 3845B010 gem batch managed to do 4Ghz at 1.160v idle / 1.168v load with 52-57C load temps which is the best LGA1366 cpu i have experienced just edging out my Xeon W3520 3845A935 gem batch which did 4Ghz at 1.184v load with 57-60C load temps with exact same cooling EK Supreme LT / TFC480 / MCP655 H20.

System:

• Intel Xeon W3540 3845B010
• EK Supreme LT 1366 / FESER 480 / MCP655
• Asus P6T6 WS Revolution
• OCZ Platinum DDR3-1333Mhz 7-7-7-24 (OCZ3P1333LVA6GK 'Animal Series')
• 512MB Inno3D 8800GT OC Edition 190.62WHQL
• 750GB Samsung SATA
• Pioneer DVR-217 DVD-RW
• Corsair HX1000 PSU
• WinXP Pro SP3 (nLite fully updated) with Vista Theme

Promising start with oc'ing 4378Mhz at 1.272v and 4487mhz at 1.320v for Super Pi 32M.

@4378Mhz at 1.272v

@4487Mhz at 1.320v

@4593Mhz at 1.424v

@4637Mhz at 1.472v

Seem to have a problem with booting into windows at >4600Mhz HT enabled but seems okay booting under 4600Mhz and then using either TurboV or setFSB to bump BCLK and cpu clock up. Going to try other cpu multipliers to make sure.

Max Validation @4821Mhz at 1.488v

• Max CPUZ Screenshot = 4681Mhz at 1.472v
• Max CPUZ Validation = 4821Mhz at 1.488v

For those asking, I'm using 0007 beta bios for this board. I've uploaded and included Asus P6T6 WS Revolution 0601 beta, 0007 beta and 0001 beta bioses here http://rapidshare.com/files/27282574...llbetabios.zip (use at your own risk).

With 6GB Corsair Dominator GT 2000 7-8-7-20 kit of memory I never got to try looser 8-9-8-x timings much with DFI UT X58-T3EH8. So now on Asus P6T6 WS Revolution, will try 8-9-8-22 2T timings to see how much further I can push memory.

System:

• Intel Xeon W3540 3845B010
• EK Supreme LT 1366 / FESER 480 / MCP655
• Asus P6T6 WS Revolution
• 6GB Corsair Dominator GT 2000 7-8-7-20
• 512MB Inno3D 8800GT OC Edition 190.62WHQL
• 750GB Samsung SATA
• Pioneer DVR-217 DVD-RW
• Corsair HX1000 PSU
• WinXP Pro SP3 (nLite fully updated) with Vista Theme

Max Validation @DDR3-2280Mhz 8-9-8-22 2T at 1.90v

Used TurboV to push mem to DDR3-2320Mhz but couldn't save the CPUZ Validation files heh. Will try again for next session

QPI/DRAM (Uncore = CPU VTT) = 1.650v
Uncore frequency = 4560Mhz

Max Super Pi 1M @DDR3-2268Mhz 8-9-8-22 2T at 1.90v

QPI/DRAM (Uncore = CPU VTT) = 1.6375v

Max Super Pi 32M @DDR3-2220Mhz 8-9-8-22 2T at 1.90v

QPI/DRAM (Uncore = CPU VTT) = 1.6375v

Now trying to combine max memory overclocks with max cpu clocks with HT disabled, but seems I'm being held back by possibly 2 factors

1. Xeon W3540 3845B010 cpu temps which at 4660Mhz at 1.528-1.544v was already idling at same temps of 46-52C as my Super Pi 32M run with Xeon W3520 3845A935 was @4794Mhz at 1.552v with exact same H20 cooling.
2. Memory clocks didn't seem to be as stable as tested at lower cpu clocks, probably due to cpu heat affecting memory stability ? Going to work on the voltages etc to see.

In meantime, here's what I could pull off @4660Mhz HT Disabled 32M Pi at 1.528v and validation @4812Mhz at 1.544v (limited by mem clock).

System:

• Intel Xeon W3540 3845B010
• EK Supreme LT 1366 / FESER 480 / MCP655
• Asus P6T6 WS Revolution
• 6GB Corsair Dominator GT 2000 7-8-7-20
• 512MB Inno3D 8800GT OC Edition 190.62WHQL
• 750GB Samsung SATA
• Pioneer DVR-217 DVD-RW
• Corsair HX1000 PSU
• WinXP Pro SP3 (nLite fully updated) with Vista Theme

Max Validation

Limited by mem stability/clock due to cpu heat ?

Max Super Pi 32M @4660Mhz at 1.528v
