Limitation breakthrough?! The initial look of DFI LP UT P35-T2R

[erwinz]

Do tell.. My DFI LANParty UT P35-T2R arrived - thanks DFI! I decided to use Scythe Infinity heatsink with modded mounting mechanism and a single Spire 120x25mm 96cfm 0.25A fan to start with. CPU in photo is Intel Core 2 Duo E6750 G0 ES.



Just flashed to 8/10 bios hehe

lucky.. hope DFI send me one.. I sell DFI here in my country..


hey eva2000 can you do a side by side comparison with asus blitz formula.. same proc same memory same tweaks.. hehehe

please please ^_^

[eva2000]

i doubt i'd have time to do side by side comparisons with exact hardware but i do have it setup to have Asus Blitz Formula, Blitz Extreme and DFI P35-T2R all running side by side but with different hardware and cpu cooling.. right now have E6600 L709A958 on Blitz Formula with corsair nautilus, E6750 G0 ES on DFI P35-T2R with scythe infinity and still trying to find a high FSB cpu for Blitz Extreme with swiftech g4 storm hehe

George see how high you can get the fsb, i hit 520 with a 6800 and 475 with a 6850 and all stopped

There must be some trick but I have not found it yet

hehehe maybe just same fsb and multi works.. of course same performance level.. hehehe..

you have such high end mobos out there..

what is a good FSB for quads?

looking at MAX FSB. My E6750 on Asus P5K Deluxe maxed out at 495-500FSB with CPU PLL 1.8v voltage. I suspect this is a cpu FSB wall as it's pretty much the same on DFI LP UT P35-T2R maxing out FSB around 495-500FSB but needing CPU PLL 1.95v since next option below it was 1.75v with clockgen voltage at 3.75v. I could boot into memtest86+ v1.70 at 506FSB but it would hang in test #7 (which might be a good test for max FSB for cpus ? ).

Notes:

• With 5:6 didvider tWR and tWTR actually show same values in memset as what's set in bios which differs from 1:1 divider where tWR and tWTR show 1 value below in memset compared to what is set in bios.

Eva, can you run please for me a winrar bench?

With 7x500FSB 1:1 divider and with 7x500FSB 5:6 divider too.

Thanks .

How about 5:6 with 4-4-4-12 ?

[eva2000]

I don't have any had that can do 600mhz 4-4-4-x without shoving 2.6+ vdimm so unlikely to be doing tests until i figure out each memory dividers behavioral characteristics for this board :

Also looking back at original first post in this thread windwithme's 7x500 5:6 600mhz 4-4-4-x 32m times were very slow compared to mine... probably loose subtimings allowed <2.0v vdimm heh

[M3kk]

Then run with 5-5-5-x .

I`am curious for a winrar bench..

Without other cpuz/memset/SG windows open a bit higher

What would you guys recommend a good HSF for the proc on this monster board? so far the Thermalright Ultra-120 Extreme would be fitted sideways so as not to hit the NB...the Arctic Cooler needed to be modded, as well as the Scythe. Would the Zalman 9700 fit without any mods?

Thanks all!

[aehmkei]

What about the IFX-14 - anyone tested this one on the board so far?

I don't know if it will fit but you might check this new Thermalright cooler.

@msgclb: thanks man! but how high is the NB of the DFI? any clearance issues with the HSF?

@erwin

contact me when ul be getting the x38 version. hehehe
