Gigabyte X48T-DQ6 CPU and memory testing

[guess2098]

Received this motherboard from GA about 4 days and here is my testing result for both memory and CPU results

-------PICTURES OF MOTHERBOARD------


here is the picture of the box




User manual, STAT cables, IDE and floppy cable, and I/O shield




Motherboard itself, blue looks pretty good but personally i like black or white color



clock-gen ID 9LPRS914EKL



Two GB LAN chips



Audio codec ALC889A from RT



8 prots of USB2.0, IEEE1394a, 2 RJ45, Coaxial and optical sound output. no extra output audio card needed




------MEMORY CL TESTS------

For a good motherboard, CL6-6-6 should reachs DDR3 1600 1.9v, YES IT PASSED





For a good motherboard, CL7-6-5 should do DDR3 1800 1.9v, Well, it does 4x1M at the time. not bad at all





For a good motherboard, DDR3 2000 1.9v with CL8 should be no problem either. It passed 32M test.





------CPU FSB TESTS------

E8400 reaches 534 benchable. not as high as i wish to go, the max i can make it boot is about 545 but won't load into windows



E6400 max out at 510 but only stable at 500, well, it is same as the memory DDR3 2000 i post on top

E8400 32m max out at about 4.5G





It is a good board, but still a lot of bios bugs need to fix. specially the memory divider it not easy to play with. Also if north bridge goes over +.575, motherboard will not boot up. i am not sure it is just my board or everyone else. For CPU voltage, when vcore set to 1.5v, actual voltage is at 1.47. no vdroop during loading. Thanks to Gigabyte PR for this review.

Nice review

I am looking at maybe getting one myself but ddr3 version , all depends if I get the 45nm cpu I am after or not, but looks good so far.

It would be interesting to see how these go with Quads.

i tested with Quads but i forget to save the picture.
max for QX9650 is 465 in my case. but this QX9650 is the very new one (and suxx, max 4.4G not even stable on any mobo). Actually the DDR3 1600 and 1800 were using QX9650 400 and 450 FSB

forget to metion, i use intel stock E6400's cooler for all the test....

guess2098: I add higher values for tRFC in this version: memset35

thx bro. i just download it.

[dinos22]

nice testing there man

guess2098: I add higher values for tRFC in this version: memset35

i hope that applies to 790i as it jumps out of range when i boot ram past 2200MHz

I was actually hoping it would have played nicer with the quads it sounds like it playes the same with them as the DQ6 x38

Have you flashed to the latest BIOS version Denny? ( it helps a lot on memory overclocking & dividers )

[Richard Dower]

Sexy looking mobo...can we get more pics of the onboard chips?, isin't there two new clock generators on the PCB?...one for memory and one for the NB?

[Amey]

Sweet looking board !
FSB could have been better i guess. especially because its X48.Is it because its a DDR3 board or something ?

Asking this because my Abit IX38 clocked FSB very nicely.550 on E8400 is easy, max i could do was 580FSB under DICE.

Could someone shed some light on this ? guess2098 , dinos22...anyone ?

Most QX9650's and QX9770's are FSB limited somewhere between 440MHz and 480MHz FSB on P965/P35/X38/X48/nF790i.
There are some exceptions, finally reaching 500MHz ( stable or not ) but that's the luck of draw effect

For the maximum FSB with E8xxx CPUs, once again, the average X38/X48 FSB overclock is around 540-560MHz, with some exceptions reaching even 600MHz FSB.

As noted several times before, FSB Limit is a CPU + Motherboard combo related.
You can get 10 E8500's and test them on the same ( part not just model ) motherboard, and reach different max FSBs...
Or you can try the same CPU on various motherboards ( even two of the same model ) and reach different FSBs.

Thanks for clarifying my doubts BenchZowner

[guess2098]

i use F4h bios, been told that is latest bios. the original F4 bios doesn't do over DDR3 1600...

Yeap, that's the good one, F4h

...what values are out of range? only tRFC?

[Supershanks]

Just got mine
& started winding it up

i use F4h bios, been told that is latest bios. the original F4 bios doesn't do over DDR3 1600...

mifgt expain why i'm not getting a stable 1800Mhz I only see official F4
GA-X48T-DQ6
Anybody help with F4H please.

thanks

Edit: Found it Linky here if any one else wants it Thanks to BenchZowner

nice runs ,which ddr3 ram you using in the tests?

Is the crazy cool easy to remove?

[Supershanks]

Is the crazy cool easy to remove?

Yes see Removing CrazyCool Heatsink , it also tells you in the manual page 16,

luck

tRFC

...fixed in this version.

what Vdimm?

[vanovich]

this is cellshock and 2.0v still testing

very nice...
