To put the T2RS Plus through its paces, it was compared against three other boards all using similar hardware and settings (except in the case of the DDR2 and DDR3 RAM). The hardware that was used for this review consisted of the following:
Processor: Intel Xeon 3070 @ 3.6ghz
Cooling: OCZ Vendetta II
Motherboard: DFI LanParty DK T2RS Plus, Abit IP35 Pro, MSI P45D3 Platinum, Asus Blitz Extreme
Memory: Crucial Balistix PC2-5300 (1:1 5-5-5-15 2t), OCZ Platinum PC3-12800 (1:1 7-7-7-23 2t)
GPU: Sparkle 8800GT 512MB
Power Suply: Cooler Master Real Power Pro 850w
HDD: Hitachi Deskstar 7200RPM 80GB
OS: Vista Ultimate 64bit + SP1
I was looking forward to this section of the review, going on my past experiences with DFI's range of boards and a few snippets I'd read on the web before being given a chance to review this board. As usual, I started with a low voltage test. Sticking to approximately 1.35v (+240Mv BIOS setting), I increased the FSB until the chip became unstable. I wasn't too surprised to find this maxing out at 3600MHz (3.6ghz), as this is the sweet spot for my veteran chip.
Showing it was capable of maxing out the chip on a low voltage setting, I continued to bump the Vcore up to around 1.6v (+450Mv BIOS setting) and went for even higher. A fair bit of tweaking later and the T2RS managed an reasonable 3900MHz (3.9GHz). Now this is not a blistering speed by any means as I've seen the chip do 4GHz, and likened to the 45nm Wolfdales it's pretty average. I felt that the main issue was due to temperatures and that the board was capable of more but would require better cooling and a lot more tweaking time.
The next test was, of course, a maximum FSB test. Leaving the voltage high, jacking up a few more settings and fiddling with GTL settings lead to a maximum bootable and stable FSB of 475Mhz.
