8X465 DFI LP UT P35 T2RG
Our 8 hour Prime95 torture test run ended at 450FSB; 460-465FSB provided around 1 hour of torture test stability and allowed us to complete all benchmarks but Prime95. The same CPU and components managed 465FSB on the DFI P35 T2R, but with a far longer 11 hour Prime95 torture test pass - without any failures. Unfortunately, the ASUS 0505 BIOS does not provide sufficient GTL tweaking ability to extend CPU core stability. To get the board close to P35 DDR2 performance we are limited to the 400 NB strap and 3:4 memory divider ratio. At higher FSB points, the 400 NB setting is the only strap that is stable enough for 24/7 use. This makes it quite apparent that Intel's engineering favors 1600FSB support and DDR3 for the X38 and future processors. DFI P35 results have also been added at 465x8. The only way to run the Maximus Formula in a fully competitive manner is to run the memory in excess of 1200MHz, which limits users to top-end DDR2 modules.
The DFI board runs DDR2-1120 very happily at low VDimm with the right modules; the Maximus is limited to either the 1:1 or 3:4 using the 400 NB strap. Using 1:1 would have limited memory speed to DDR2-930 on the Maximus, which is quite low unless you run CAS 4-3-3 timings. Such low latency timings required a very high VDimm, and 1N did not seem to work at this speed either, so we chose to stick with DDR2-1240 CAS 5-5-5-15, which was possible at a reasonable 2.2V.

...handle DDR2 ECC memory? I for one would like to know. ASUS seems to be of two (or possibly more) minds on the matter stating conflicting information all around the product pages for their respective X38 board offerings. Then again, the P5W DH Deluxe still seems like a smart choice, considering the very small performance delta between the i975x and later chipsets. Also, ASUS claims Penryn support for several of their "mature" offerings, including the P5W DH Deluxe.AnnihilatorX - Friday, November 9, 2007 - link
Personally I would recommend everyone including enthusiasts to not to buy over-priced performance RAMs.And of course looking at price at the moment to choose DDR2 over DDR3
A low latency low frequency RAM are potentially *much* cheaper than a high frequency one. The performance discrepancy is at most 5% which relates to perhaps 2-3FPS in a game. This has probably the lowest cost-to-performance ratio of a system component.

when will the new bios be ready, and i exspect it, this time to make it possible so it can see, ddr2 1066 at long last.nleksan - Wednesday, November 28, 2012 - link
I have been looking for a motherboard for a recently acquired (given to me free of charge) set of somewhat older but almost entirely unused (i.e. no more than 100hrs use on anything, most have around 20-40hrs; came from 9 different full-or-partial PC's) hardware including:- Core2Duo E8600 (under 20hrs use, known to run stable at 4.5Ghz on air, 4.9Ghz on water)
- 4x2GB G.Skill DDR2-1066/1150 4-4-4-9
- 4x1GB OCZ DDR2-1066 4-4-4-12
- 3x 250GB Samsung Spinpoint SATA3Gbps HDD's
- 2x 150GB WD VR SATA3Gbps 10krpm HDD's
- 1x WD WD800BB 80GB SATA3Gbps HDD
- 4x WD2500JB 250GB SATA HDD's
- 3x WD Caviar Blue 320GB (AAKS) SATA3Gbps HDD's (repurposed for new X79 build)
- 2x Seagate 7200.7 160GB E-IDE HDD's
- 3x Hitachi Deskstar 320GB SATA3Gbps HDD's
- Enermax 690W High-Efficiency PSU
- Antec SOHO Server Case with 8x3.5" bays/5x5.25" bays (fits a Xigmatek 4x3.5-in-3x5.25 with 120x25mm fan converter nicely, for a total of 12xHDD's) and ripe for some heavy modifications
OR
- Thermaltake XASER V Limited Edition with 5x3.5" bays + 6x5.25" bays
OR
- Buy a new sub-$100 case for this (Rosewill ThorV2 would be nice for price, Antec 1100/1200/P283
- DD Maze6 CPU Block
- 2x DD Maze6 GPU Blocks
- 3x Swiftech MCW82 GPU Blocks

I have been looking for two things: a Motherboard and a GPU (or pair of GPU's), and while this will be a Home Server/Media Server, it will also function as a F@H box. I am thinking that 2x 9800GTX+'s or 2x GTX260 216core's in SLI would suffice, but perhaps not? I don't know much about the C2D/C2Q era MB's/GPU's....
I have been looking at the following boards:
- Asus P5Q Premium (huge amount of connections, would allow 4x GPU's for F@H or 3xGPU + 1x RAID Card)
- Asus Maximus Extreme
- Asus Rampage Extreme
For GPU's, I've been really considering the following, from lowest cost to highest:
- 2-3x 8800GTS 512MB (G92)
- 3x 8800GTX's
- 2-3x 9800GT's
- 2-3x 9800GTX+'s
- 2x 9800GTX2's
- 2-3x GTX260(216core)-to-GTX295's
- 2-3x GTX460's-to-GTX480's
Anyone remember enough about this older hardware to help me out?
