ASUS NCCH-DL Successful Overclocking Summary
8/7/05
Hardware Used:
--------------
1 each - ASUS NCCH-DL Dual Socket 603/604 Intel 875P ATX Server Motherboard
2 each - Intel Xeon EM64T 3.2 Nocona 800MHz FSB Socket 604 Processor Model BX80546KG3200EA w/factory heat sinks & fans
1 each - LSI Logic MegaRaid SATA 300-8X with 128 onboard cache memory
2 each - Seagate Barracuda 7200.8 ST3300831AS 300GB 7200 RPM Serial ATA150 Hard Drive
4 each - CORSAIR XMS 1GB 184-Pin DDR SDRAM DDR 400 (PC 3200) Unbuffered System Memory Model CMX1024-3200C2PT
1 each - ATI All-In-Wonder X800 XT 100-714200 All-In-Wonder Radeon X800XT 256MB GDDR3 AGP 4X/8X Video Card
2 each - LiteOn DVD +-/RW Dual Layer Burners
1 each - Full Tower Aluminum case
1 each - PSU SKY HAWK 620W ATX-GM620SC Power Supply
(All items purchased from NEWEGG.COM)
Software Used for testing:
--------------------------
Everest Home Edition
CPU-Z
Tweak Manager
Windows XP Pro 32 bit & 64 bit versions
Current Stable Settings:
------------------------
DIMM Voltage - set to 2.8v in BIOS yielding 2.75v effective - Corsair testing voltage
Memory Latency - 2-6-3-3 (Corsair recommended setting) - set in BIOS
Core voltage - left alone at 1.5v
Video BIOS Cached - DISABLED
System BIOS Cached - ENABLED
FSB Speed Setting - 212 (stock is 200)
Multiplier - left alone at 16x
Motherboard Bus Pin setting fixed at 200FSB with jumpers
Windows XP defaulted L2 cache to 256k - using Tweak Manager reset it to 1 meg to match CPU L2
One side of case removed with small table fan blowing on MB and drives (very quiet)
A. Before side case removal - CPUs ran around 55 degrees and ATI video around 63 degrees
B. After side case removal & small table fam - CPUs run around 38 degrees and ATI around 50 degrees
Promise SATA RAID Controller - DISABLED - using LSI Logic Controller instead
Current Results in Everest Screens:
-----------------------------------
CPU - 3400 (i.e. 3.4 processor speed)
FSB Speed - 212.778 (849.5 as shown in CPU-Z)
CPU Fan Speeds nominal and quiet
CPU Temps - around 38-40 degrees (same with MB over-all)
ATI Operating Temp - around 50 degrees
Comments:
Have tried a bus setting of 213 but had occasional problems. At 212 all seems stable. Leaving the Video BIOS cached seemed to cause some video problems - so I disabled it in the MB BIOS. The whole tweak yielded around a 6% increase in speed - i.e. 3.2 gig processors running at about 3.4. Windows XP x64 also works fine with the above settings. However, 64 bit audio drivers are hard to find.
