DFI first DDR3 motherboard, UT X48-T3R Heatsink by Thermalright

[Praz]

That speed seems to be the sweet spot for the board as for as voltages go.

Anyone able to get over 530 fsb stable on this board? Seems to be the wall for me so far.

[d3885u]

Is it because of limitation from the chipset or the BIOS from DFI?
Why this mobo can't pass 530 FSB like the DDR2 version...???
I'm still wondering why until right now...
Coz if I take a look at the other competitor like Asus RE could pass 600 FSB so easily...
So what's the point to make that different by very big margin I think..??

[BlackDragon24]

It is a BIOS limitation...I've seen 550+ fsb on other dfi x48 boards.

I've seen it as have many others.

There are quite a few of us over at dficlub who cannot get over 535ish fsb stable no matter what we do.

Might be time to switch boards.

BlackDragon24 - I am in the same boat as you although you have gotten a bit further than me, best I can accomplish is 510FSB while still maintaining any stability? Like many here I've been working at it for many months and have tested each and every BIOS released so far but still can't break much over 500FSB? Although there has been much improvement since early BIOS versions but I just don't see a miracle BIOS to be released anytime soon and I'd be surprised if DFI continues to release new BIOS versions in the near future (but I could certainly be wrong). Granted 500FSB is enough for 24/7 use but I'd like to be able to push things a bit further if for no other reason than its just fun to do so! With that said I've been trying to figure out a new motherboard to switch to, even been considering going back to DDR2.

The cooling is supreme what are the temps in load/OC?

[Roger_D25]

Major Settings
CPU: 4050Mhz (1.250v)
RAM: 1800Mhz @ 7-7-7-18 1T (2.00v)
NB: 1.566v
SB: 1.51v
VTT: 1.210v

Idle Temps
CPU: 26C-28C
NB: 34C-41C

Load Temps
CPU: 48C-56C
NB: 45C-53C

All voltages listed above are the BIOS settings (actual voltages tend to be a bit lower at idle and the gap grows under load). I only listed a few major settings to give you an idea of what my settings are in relation to temps under idle and load. The large temperature range I've listed is because at the moment I'm under straight air cooling (stock cooling) except for CPU in which I'm running a Thermalright XP120 Extreme with lapped base. The system is setup on a test bench (not in a case) so expect somewhat higher temps if system is mounted in a case (depending on air flow through case). Feel free to ask if you have any other questions

First of all great job getting your system stable on this board with those settings (I'm sure it was no easy task)! I'm especially impressed with that FSB speed and the fact your running the 400/1333 divider, that can be a very tricky setup to even boot on so getting it stable is awesome! Add to that your running a 2 x 2GB kit of DDR3 makes it every more impressive! With that all said thanks for posting all those settings, I realize its not quick or easy to copy down all those settings and I'm sure many people will benefit from them. I'm sorry if I have already asked you (I looked back a few pages and couldn't find it) but do you know what IC's are on your OCZ Reapers? Praz did some great work on his 2 x 2GB kit but I couldn't get anywhere with my 4GB kit (running D9GTS). I have a feeling that I need to work with getting the Drive Strenths and DLL Skew Models correct before I'm able to push my 4GB kit to decent clockspeed (heck I can't even get them working at default clockspeeds and timings)! Thankfully my 2GB kit of STT Project X runs very strong at low voltage! Well thanks again man for all your help!

[BlackDragon24]

Thanks!

It was no problem at all to post the settings....I had already done it here.

It's kinda like a diary OC thread...check it out if you wanna go thru the trials and tribulations....what is interesting in my case is that the 400/1600 seems to be a lot harder to stabilize. Unfortunately I don't know the IC type on my reapers...any way to find out without ripping the heat spreaders off?

[BlackDragon24]

Ok couple of updates...been working on tuning the 400/1600 divider and it has been to say the least, a challenge. But its looking good.
