Cool Intel Core 2 Extreme X6800 B2 + Asus 680i Striker Extreme

Time to check out my X6800 L627A872 retail cpu on Asus 680i Striker in preparation for SLI benchmarks.




System:
  • Intel Core 2 Extreme X6800 L627A872 B2 Step 6
  • Swiftech Apogee/Radiical Triple Fan Single Pass Rad/MCP655 + Kayl 100W Custom PSU
  • Asus 680i Striker Extreme 0402 bios
  • 128MB Gainward FX5200 PCI card
  • 2GB OCZ PC2-8000 Titanium Alpha VX2
  • 4x80GB Hitachi 7K80 SATAII Raid 0 on SATA3 to SATA6 ports
  • Pioneer DVD Burner
  • 600W OCZ EvoStream

Small ffts load


While the cpu used slightly less vcore it was still warmer at idle and load than when X6800 L627A872 cpu was on P5B Deluxe @3.6Ghz http://i4memory.com/showthread.php?t=3635 with Swiftech G4 Storm/Thermochill 120.3 and MCP650 Pump. This isn't unusual as all my E6600/E6700/Q6600 ran hotter on Asus 680i Striker Extreme than they did on Asus P5B Deluxe.

X6800 on Asus P5B Deluxe @3.6Ghz
idle @1.4v vcore = 34C/35C at 26C ambient
load @1.38v vcore = 51/52C at 26C ambient

X6800 on Asus 680i Striker @3.6Ghz
idle @1.38v vcore = 44C/45C at 29-30C ambient
load @1.36v vcore = 58-60C at 29-30C ambient

While warmer relative to on Asus P5B Deluxe, this X6800 still ran a good 6-8C cooler under load on Asus 680i Striker Extreme.

Re: Intel Core 2 Extreme X6800 B2 + Asus 680i Striker Extreme

Seems this X6800 runs alot hotter under load on Striker than it did on P5B Deluxe, but still relatively cooler under load than my previous core2 cpus.

Playing with lower multipler of 8x to see how it goes. 3392mhz at 1.26v vcore under load resulted in 54-55C load temps in 30-32C room ambients (~4-5C hotter than first post's room ambients).

Re: Intel Core 2 Extreme X6800 B2 + Asus 680i Striker Extreme

Now to try out 4x1GB G.Skill 6400PHU2 2GB HZ Micron D9GMH 629 batch for the first time on Asus 680i Striker Extreme.



Some folks say they're having issues with 4x1GB modules so thought I'd try it out at the below memory clock speeds.
  • @400mhz 4-4-4-12 5-22-6-8-42 at 2.15v vdimm

@500mhz 4-4-4-12 5-22-6-8-42 at 2.25v vdimm


Started testing by dropping multiplier from 11x to 9x and upping FSB to 400FSB and 4x1GB G.Skill 6400PHU2 2GB HZ Micron D9GMH 629 batch @500mhz 4-4-4-12 at 2.25v vdimm bios set.

Re: Intel Core 2 Extreme X6800 B2 + Asus 680i Striker Extreme

Back with my 2x1GB OCZ PC2-8000 Titanium Alpha VX2 memory and I surprised myself in breaking my personal best single Super Pi 32M time at 3600Mhz core2 duo cpu clocks - and my PB was on 965P/975x of around 13min 37-39 seconds.

But this is on Asus 680i Striker of all boards and with sub 600mhz memory clocks. But guess tight timings + tight sub timings helped with just 533mhz 4-3-3-4 2T at 2.35v bios set vdimm

  • Old PB Single Super Pi 32M time on Asus 680i Striker Extreme = 13m 52s 313ms
  • New PB Single Super Pi 32M time on Asus 680i Striker Extreme = 13m 33s 812ms and 13m 32s 907ms

Old PB Single Super Pi 32M time on Asus 680i Striker Extreme



New PB Single Super Pi 32M time on Asus 680i Striker Extreme



better run


1M


Everest Ultimate Bandwidth


Yes the X6800 being B2 stepping might have helped too against my old E6600 B1, but I'm putting my money on the tight subtimings being the main factor in such fast times

Re: Intel Core 2 Extreme X6800 B2 + Asus 680i Striker Extreme

560mhz 4-3-3-4 2T 3-1-3-6-34 at 2.5v vdimm


Yup tight ass main and sub timings on Asus 680i Striker really do make a huge difference. Who would of thought I could pull off sub 13min 30s Super Pi 32M times at 3600mhz with a 680i chipset motherboard without even clocking memory above 560mhz (DDR2-1120) speeds!

Jumped all the way to 560mhz 4-3-3-4 2T with sub timings of 3-1-3-6-34 at 2.5v vdimm bios set. According to memtest86+ v1.70, reported bandwidth at 560mhz 4-3-3-4 2T was 5413MB/s versus at 533mhz 4-3-3-4 2T of 5209MB/s.



Digital camera snapshots of 32M run with 3x cpuz windows open + memset window.









Final result = 13m 28s 391ms



Re-ran 32M but with cpuz and memset windows closed = 13m 27s 719ms !



1M time = 13.922s



Everest Ultimate Bandwidth with 43.3ns latency!



Hexus Pi Fast



All I can say is bloody fast for 680i chipset

Re: Intel Core 2 Extreme X6800 B2 + Asus 680i Striker Extreme

Managed to clock ram up to 600mhz 5-3-3-3 2T but with even further tighten the sub timings even more but had to loosen CAS from 4 to 5 in order to keep vdimm at 2.5v bios set ceiling (within OCZ warrantied max vdimm of 2.52v)

Memtest86+ v1.70 reported bandwidth
  • @533mhz 4-3-3-4 2T 3-1-3-6-30 at 2.35v vdimm = 5,209MB/s
  • @560mhz 4-3-3-4 2T 3-1-3-6-34 at 2.5v vdimm = 5,413MB/s
  • @600mhz 5-3-3-3 2T 2-1-2-8-24 at 2.5v vdimm = 5,625MB/s

600mhz 5-3-3-3 2T 2-1-2-8-24 at 2.5v vdimm




Super Pi 1M


Super Pi 32M


Everest Ultimate Bandwidth with 42.9ns latency!


Hexus Pifast


That's fastest I've managed to run Super Pi 32M at 3600mhz cpu speeds on any core2 platform to date (including Asus P5B Deluxe/P5W DH, Intel D975XBX, DFI ICFX3200) !

Yup further tweaked managed to shave a few seconds off

Re: Intel Core 2 Extreme X6800 B2 + Asus 680i Striker Extreme

Yeah very fast indeed

4000Mhz - 10x400FSB / 3950mhz - 10x395FSB


The Asus 680i Striker Extreme just runs my X6800 hotter than on Asus P5B Deluxe at higher vcore settings ~10-13C hotter at idle.

I tried X6800 @10x400FSB = 4000Mhz at 1.56-1.62v vcore and idle coretemp reported 57-67C versus same X6800 on Asus P5B Deluxe at 4092mhz at 1.65v vcore only reporting coretemps idle at 45-47C.

So only could manage 1M times for X6800 @4000mhz at 1.6v (1.57v load) on Asus 680i Striker Extreme. Higher vcore just meant reboots in windows under load (maybe vdroop too much at higher vcore like on P5B Deluxe ? )

Super Pi 1M


Everest Bandwidth with 42.7ns latency


But at much lower vcore of 1.56v idle/1.54v load, coretemp reports more reasonable idle temps and I can manage 3967-3972mhz at 1.56v idle for 32M with lower mem clocks but once hit 600mhz 5-3-3-x timings seems tight sub timings cause instability until I drop cpu down to 3950mhz at 1.57v idle!

@592.5mhz 5-3-3-5 3-1-6-8-28 2T timings at 2.5v vdimm bios set, Memtest86+ v1.70 reports 5540MB/s memory bandwidth.

Super Pi 1M


Super Pi 32M


Everest Bandwidth with 43.0ns latency


Compared to my old previous max 32M on Asus 680i Striker
