Computex Taipei 2008 Gigabyte showcase GA-EP45 Extreme, GA-EP45-DQ6 high end mainboards
Posted on 05/29/2008 @ 05:35 PM

At Computex Taipei 2008, Gigabyte will showcase GA-EP45 Extreme, GA-EP45-DQ6 high end mainboards.

GA-EP45-Extreme

The board supports Intel® Core 2 Multi-Core and 45nm processors with FSB1600MHz with scalable performance with DDR2 1200 memory.

Outstanding cooling design with Pure Copper thermal design featuring Water Cooling. The 2 PCI-E 2.0 x16 graphic interface plus PCI-E 2.0 x4 with Quad CrossFireTM support for ultimate graphics performance

[loonym]

The heatpipe designs are getting more elaborate all the time. Nice layout I think, I like the slot config.

[Ace-a-Rue]

yeah!...this is what stands out, which peaked my curiosity:

[loonym]

i am currently using GSkill DDR3-1600, 2 x 2gb...works well, but i was careful with the voltage...i didn't take it over 2.05v.

this board is excellent!...i would rate it 9 out of 10.

Is that kit F3-12800CL7D-4BGHZ? If so would you mind sharing setup, timings and anything else useful? I'm currently using them at 1800 with 8-8-8-20 2T 1.95v all others auto. Is there something better I can do with these?

[Ace-a-Rue]

are you kidding me...sheez!..i never got up that high even with my E8500....i guess my sticks are doing sh*t for me!

this is what i did with my 9650:

Ok so I'm not totally on the wrong track... good to know. Thing is a 2x1gb ocz flex kit really can't produce much better results. Maybe it's the cpu, I had a chance to trade for a 9550 and now I'm wondering.

no, no!..2 x 1gb kit will do better than 2 x 2gb kit, just your sticks (we have the same) are doing better than mine.

[memory]

Testbed:

CPU: E8400
Memory: Gskill GBPI PC12800 (1600) 2gb x 2 kit
Mobo: Gigabyte X48T DQ6 Rev 1.1 Bios (F4h)
Gpu: Gainward Bliss 9600GT 512mb Golden Sample
HDD: IDE Hitachi 80gb 7200rpm
PSU: Vantec Ion2 500 watt
OS: XP Pro SP2

Memory is 7-7-7-18@ 2T@1.9vdimm rated by manufacturer

Of course, I am not going to run at manufacturer rated clock speed

900mhz@8-8-8-8-18@2.1vdimm - Pi 32 million passed


900mhz@8-8-8-8-18@2.1vdimm-01se


900mhz@8-8-8-8-18@2.1vdimm-03


900mhz@8-8-8-8-18@2.1vdimm-05


900mhz@8-8-8-8-18@2.1vdimm-06


So far, Bios F4h is the best bios for memory oc. Bios F5a and F5d failed to get the memory stable at 900mhz=(.

Here is the memory module

[loonym]

I've been having good results and stability with bios F4D so I really haven't tried others for more than just a look. All my benches as well as 24/7 operation running boinc have been pretty much with the settings I posted. I'm never going to get any higher with this or any other board and the x3360's because they won't run past fsb 475 or so.

[Ace-a-Rue]

pretty well 475 fsb is it for quads on air...i think i got to 480 fsb but that was pushing it with voltages...a bit beyond my comfort zone

[loonym]

Yes I agree and with all the reading I do I guess I knew it even though I wanted to prove it wrong, lol. It's so much fun to try and beat the odds you know?
I have had this plan in the back of my mind for awhile... There's a local tech school that has hvac/hrac courses and a pretty nice shop. My thought is to approach 1 or 2 of the students with the idea of building a really nice 1hp or so ss for me as a school project with me funding the neccessary supplies. Never hurts to try

[MagnumMan]

Hi folks,

I'm working on another machine for my office this time. GA-X48T-DQ6 with a QX9770, Quad 15k SAS Enterprise and a Promise SuperTrax 8650 SAS controller; also 8GB of DDR3-1600 memory from OCZ. Now I have the memory passing at least 1 pass and still running no errors, 4x2gb at 8-8-8-25-2T with 900mV CPU drive and "Normal" or "Auto" skew.

I am using BIOS F5C which I found with google. Under BIOS F4 I couldn't even get 1 stick of memory to pass memtest with DDR2-1600 settings, albeit I was trying at 7-7-7-24-2T 1.9V, you know the rated specs for this memory (should have worked, right)? Anyway...

When I go into the BIOS on F5C and try to enable the FSB control, it quickly disables it again. I have absolutely no idea why. I want to try the memory at DDR3-1800 with FSB 450 but maybe this BIOS has a bug in it, can anybody else comment on this? Thanks.

(PS. In my signature rig below I am swapping out the 750W Power for a 1000W power because my Kill-A-Watt recorded 1010W in 3dMark06 peak so don't razz me about that!)

[Supershanks]

BIOS F5C is flawed for the reason you found. Use F5A or F5D

luck

[MagnumMan]

The link to station-drivers has no file found so where can I get F5D now?

[Supershanks]

Link works for me

see * GA-X48T-DQ6 BIOS v.F5d
It's in the 2nd box down

Gigabyte company released new Bios version for its motherboards

In new version some errors are fixed and work improved

To download bios update choose your motherboard model from following:

MagnumMan u have a PM
good job Fugger sorted us out

[MagnumMan]

Well with BIOS F5D and a little bit of time I was able to get 4x2gb (2 kits of OCZ3P16004GK) running stable under memtest.

FSB 410
Mem DDR3-1640 +.40V = 1.92V
Timings: 8-7-7-20-2T
All other settings on auto in timings
FSB +.20V
NB +.20V
CPU x9 (QX9770) = 3.7GHz (not tuned yet, I hope to break 4GHz...)
CPU at 1.35V right now
CPU Driving 900mV (normally 800mV)
No skew, left on "normal".

Not too bad for 4x2gb dual rank memory these days. The memory does get pretty hot though I would almost recommend a fan right on the memory to help out. They almost burn to the touch when pushed.

I mounted a 40x40x20 fan on the northbridge so it has active cooling (I left the heat pipe solution alone and put a fan over it securely, plugged into the "NB" fan header). The NB is almost warm to the touch near the base when running memtest. Before the fan it was getting almost too hot to touch.

Anyway so far so good. I tried 8-7-7-18 but the system kept boot-looping. So this looks like the best timing I can get with 4 sticks. Good board, seems pretty stable.

good news!...which bios are you using?

[MagnumMan]

I finally stabilized a rig with this board. Took more reboots than I thought it would. Here are all the specifications to help people out who may be setting up something similar.

[Ace-a-Rue]

can you get to 4 ghz and run any benches?

[MagnumMan]

Unfortunately Core #1 (numbered 0 through 3) dies above 3.8GHz at any voltage and quickly too. Since temps are already 80C (175F) !! I prefer to keep that where it is. Took me 5 days to stabilize this rig, I'm done doing that. This is a development rig for my office which I will be using to build an app that takes over an hour to compile/link on an Opteron 248 (2.2GHz) system. I expect that time to be around 20 minutes with this new hardware. Keys to stabilizing were:

1. running memtest to find the memory stable settings (DDR3-1640 8-7-7-20-2T), anything over that was failing frequency-wise.

2. running prime95 small FFT to isolate the CPU's potential, which seems to be 3.8GHz (this is pretty lame because other people have gotten to 4.0 GHz, so I think I got a bad CPU, but it's still well within engineering tolerance, I suspect).

3. upping voltage on the FSB and MCH, FSB at +.30V locked up the system; MCH at +.40 locked up the system.

4. setting the CPU drive to 900mV

5. Manually setting all the secondary memory timings to be one higher than the auto selection was, i.e. 5 became 6.

The Scythe Mugen heatsink is so large it rests on coils too, which may be preventing it from getting the tightest fit possible on the CPU... 80C seems pretty excessive even at 1.38750V to me. Then again I am used to water cooling (see sig) and this doesn't have it.
