DFI X48 LT T2R: Floats like a Butterfly…

Company of Heroes
Despite having been around for a while, Company of Heroes is still one of the best strategy games available. The game is heavily GPU limited but also requires brute CPU processing power to keep things smooth during heavy action. The built-in benchmark is very responsive to GPU as well as CPU scaling, hence we think it provides good insight into overall system gaming power.
DFI scores lower at stock speeds due to the very loose default BIOS settings the board employs. At 4 GHz, the results are a little closer; either way the frame rates of all the boards should ensure solid game play at these settings. Actually, we could not notice any difference in game play between the boards at stock or overclocked settings. At these frame rates, one board scoring better than the other really does not make any difference unless you like showing off for others.
DFI's board falls behind EVGA across the range of testing at higher resolutions - certainly not in an excessive manner, but a victory certainly would have been more inspiring. Having benchmarked the board through a variety of tests, if squeezing performance is important to you, a wiser operating point will undoubtedly come at 450FSBX9 on the DFI board - if you find you can get away with a tRD of 6 or so. At 500 FSB, the board will not run a value of 7, which may have helped the scores by a few FPS here and there.

hi,can anybody tell me if the ocz flex 9200 4gb-kit(2x2048) workz too instead the four 1024 plz.

I miss the analysis of other features than just plain memory latency.Max fsb overclock, max mem overclock, etc?
Running the board at 400fsb seems boring - lots of P965 boards can best that. Tons of people don't buy these multiplier unlocked chips.

Hi,Dual core 45nm's top out at around 510-515FSB using air cooling. Most of the quad CPU info is in the review.
We are looking at perhaps adding some more content tomorrow. Mainly 2x2GB and 4X1GB maxmimum stable overclocks and best operating points - using air cooling.
When Using 45nm dual core CPU's X48/X38 chipsets are really only 'good' to around 500FSB tops for 24/7, after this VMCH requirements and total stability with low tRD becomes futile rather quickly. SOme of the DDR3 boards are a little better in this regard, though this overhaed always comes at a high voltage price when used with a suitably high CPU multiplier.
65nm CPU's in dual core form may cruise upto 550fsb with some work, perhaps a 67% GTL table will help for that. Many of the benches in the review were run at 8x500FSB just to reflect the maximum 24/7 somebody is likely to be able to achieve and/or use consistently. FSB values over this are prone to failure in applications like PC Mark Vantage or 3D in some instance (even with lots of GTL work). Our E8500 processor managed 510FSB with 4X1GB maximum stable on this board, while using 2x1GB memory allowed me to boot at a around 520FSB - though this was far from being called stable.

Thanks for taking the time to respond.Unfortunately, I have not been keeping up with the latest tweaks on the best boards. Thanks for the detail, though. :)

Am I imaging things or something fishy is going on here?The board has 2 PCIe 2.0 x16 slots - from the X48 MCH. OK.
The board has the following PCIe devices connected to the ICH9R:
1. PCIe x1 slot
2. PCIe x1 JMB363 SATA/PATA controller
3. PCIe x1 Marvell 88E8052 Gigabit Ethernet controller
4. PCIe x1 Marvell 88E8053 Gigabit Ethernet controller
5. PCIe x4 slot (physical x16)
IMHO in this situation the x4 slot can be utilized as x4 only if at least 2 of the PCIe x1 devices are disabled? (if so, then wich exactly?) But this is not mentioned anywhere - neighter in the review, nor in the official DFI specifications or manual. Also, in the manual there is no BIOS settings description section - so I can't find what does the "PCIE Slot Config - 1X 1X" option stand for? (I assume for putting the x4/x16 slot in x1/x16 mode when the other devices are not disabled?)

Great stuff.I have one concern though.
What are you using to test stability for 8 GB?
I have found that what people like to consider "stable" is only stable because of the use of applications like P95, Everest, OCCT, & Memtest86+, which don't tend to really stress 4+ GB RAM & the Northbridge to the same extent as multiple instances of HCI Memtest or as LinPack.
Just curious is all.

HCI memtest seems the way to go for me for memory NBGTL related stuff.For CPU core testing Prime/PC Mark Vantage (Blu-Ray test).regards

great review RajinderIt was very in-depth and well written. A big chunk of the memory portion seemed to focus on micron D9 chips. I have the 4gb Gskill(powerchip ICs) and would really like to see a write up on this board involving "other ICs" and maby a guide with 65nm quads.
also have you tested the performance differential between the intel and jmicron sata ports?
well done

HI Andy,Although the guide says Micron I did add a comment on TRFC and double density modules. tRAS adn tRFC are the 2 tiimings that need to be changed for the most part. The boards will hold upto 450FSB and a dual core 45nm 'stable' with most of the chipset registers set to fast/more aggressive. Comments are already in the guide for 65nm CPU's pertaining to leaving the GTL controls at defaults - nothing more is really needed tbh..

Replacing two of the six USB ports ith two eSata ports would seem to make sense. Not sure why they didn't do this on a board in this price range.
