DFI UT X48-T3RS LanParty - Living Review

[WILSON]

Its batch Q820A670 but they are sending me another tomorrow so i will test that and then decide which to keep . If the probe is faulty will the rest of the cpu be good or is it hard to say?

I have a stuck probe also but it clocks like hell so I keep it. The memorys though can't run at stock nomatter what I've try so I'm honestly getting very tired of this DFI board.

Aye, one of the probes on my QX9650 is stuck too, but it doesn't worry me too much, the other 3 are within a respectable tolerance of each other.

On a slightly different note, I've decided (for now) to stop trying to overclock the FSB, at least until DFI release a bios that clocks quad cores a bit better. I got a bit fed up trying all kinds of different settings for GTL ref voltages for both CPU and FSB at 1.2 VTT (tried 61%, 63%, 67% and everything inbetween...) I can find areas where it seems more stable, but not quite bang on using 0725, which is actually better than the previous bioses, so I'm hoping further releases will fix it. Fingers crossed.

At the moment I'm on 3.6GHz CPU, 333MHz FSB, 1333MHz memory, with timings of 6-5-5-15 1T and it's rock solid, with only a bit more NB voltage and CPU voltage (I'm not at home so I don't remember the exact settings, but I think it's about 1.29V on the CPU and 1.35V on the NB). GTL voltages are set to auto, and pretty much everything else is set to auto (bar the memory timings ofc).

Could a bad clocking CPU be responsible for not reaching any high FSB overclocks, considering it clocks alright and within expected voltages with the multiplier? I can't get past 350-360 FSB without having to fiddle with GTL voltages, which to me seems quite low, but this is my first overclocking experience since clocking an Athlon X2... so I really don't know how it should be going to be honest.

That is a low FSB but I don't think it's processor related. DFI boards in general seem to top out 15 - 30 FSB lower then most other boards using a quadcore. And these results are with GTLREF voltages tuned on the DFI boards and the other boards on auto.

The T3R is going to produce results even lower. Even with a dualcore, VTT and Northbridge voltage has to be run higher then what one would expect. With having to work around what is broke in the BIOS and the immaturity of the BIOS in general your results are probably pretty close to what one can expect.

Impossible to say...good luck with the new one though. I haven't heard of any bad clocking E8600s yet

How do you mean the memory wont run at stock?

I think he means when you leave the strap on auto because i can only use the 400/1333 strap or i get c1 errors or just can`t boot full stop.

[Clunk]

You all updated BIOS wise?

[WILSON]

Yep im on 725 with my ram @ stock settings running 2T and it passed memtest with 400/1333 but cant try most of the others as it over/underclocks my ram too much or will not boot?

[WILSON]

Got another Q820A670 so my guess is that its a funny batch as ive got the same problem with the probe on core2 being faulty. Has anybody else got this batch and has the same problem?

EDIT when temp goes above 37 it works???? very strange as it stops at 37 when it drops back down.
