GIGABYTE GA-EP45-UD3P Mobo - "We have a winner!"

itshondo · Oct 4, 2009

What a great piece of hardware!

I installed a Q9550 Quad Core CPU, 4 X 2 GB Gskill DDR800 memory and the rest of my components and went right into the BIOS.

First thing - up the voltage on the memory to 2.0 V (2.0 - 2.1 V spec) and then I upped the FSB to 400 for an overclock from 2.83 Ghz to 3.4 Ghz.

I kept the multi at 8.5, and the ram at 800 (2.00 X 400) with the timings on spec at 4-4-4-12, saved & then went into Windows 7 for some testing.

It never skipped a beat and primed for 2 hours without any errors.

So then I went back in and upped the FSB to 450 for an O/C of 3.82 Ghz. I left the divider at 2.0 and the Gskill handled the increase to 900 without any issues at all

During testing the max temps got close to 70C so I stopped Priming until I reseat the HSF.

So for me, I feel good about sticking with the socket 775- this will last me for some time to come.

And what is going to happen to the GA-965P-DS3 & Conroe 6600 it replaced? Well, they go out in the mail on Monday to my brother- he's going to put together a new rig for my Dad.

Ok, 4.011 ghz (472 X 8.5), memory at 2.00 X 472 for 944, all on stock volts & aftermarket air cooling.

Testing now.

running too hot- going for a reseat.

MattNo5ss · Oct 4, 2009

What did your temps get to at 4GHz? The posted RealTemp screen shows 48C as maximum...which can't be right

The pic above is after 5 min of light work- when I started priming Real temp 3.00 showed it rapidly climbing, and I ended the stress test at 69C.

I gotta reseat the heatsink as I think it's WAY too hot. I think one leg might have popped.

itshondo · Oct 4, 2009

I got up this morning and reseated the HSF. The temps are still too high.

I noticed that the base of the heatsink had corner marks ie indentations from the corners of the cpu.

So this cpu needs to be lapped (like I did to my Conroe) in order to get the temps back under control.

What hs/f are you using?

A Coolermaster CM RR-CCH-L9U1-GP HSF

I lapped the new CPU & base of the HSF, used some new AS5, and my load tepms are still too high.

I'm going to set the O/C back to stock to see where it is-

itshondo · Oct 4, 2009

Well, here's the latest -

Room temp 77F
Stock Vcore

Stock settings - 8.5 X 333 / 2.83 Ghz

Idle - 37C, Max 51C

Overclock of 8.5 X 400 / 3.4 Ghz

Idle - 39C, Max 59C

Overclock of 8.5 X 450 / 3.82 Ghz

Idle - 42C, Max 69C (too close to the 71.4C Intel Maximum)

So even with a fresh/good cpu & HSF lapping, fresh Arctic Silver 5 and anbient room tems of 77F, the temps are getting to high with the cooler I am currently using.

So I may be looking for another cooler with strnger performance so that I can run 24/7 at 4 Ghz.

Any suggestions would be appreciated.

MattNo5ss · Oct 4, 2009

Yeah, I think you need a 120mm heatsink to get the temps down. Here's some options. I would suggest Xigmatek HDT-s1283 for Performance/Dollar.

$45 + FS Xigmatek HDT-s1283V Dark Knight
$40 + FS Sunbeam Core-Contact Freezer
$50 Tuniq Tower 120
$75 Noctua NH-U12P
$51 Thermalright Ultra-120 Extreme
$65 Prolimatech Megahalem

itshondo · Oct 4, 2009

Thanks for the recommendations.

I did lapp the cpu & HSF today as well, but the HSF is just not up to 3.8 Ghz & beyond -

That should help, my temps dropped by 4C after lapping my E8400 with only 600 grit paper. How much of a difference was there?

OnDborder · Oct 5, 2009

Nice lapping job.
What do you have the vcore set at?

itshondo, contact sno.lcn or earthdog if you'd be interested in writing an article about this for overclockers.com - they will help you.

If you aren't interested, you should be.

Ok, I'll send them a PM- should be no problem writing an article for me (other than time) as I own these sites -

I ordered a Prolimatech Megahalems Rev. B heatsink to get these temps down.

When I get it installed I'll report back with my temps at my overclocks.

Looking forward to a stable 4.0 Ghz -

I'm still loving my UD3P - this board is so good I hate to upgrade.

You chose wisely on the HSF. What fan(s) are you using with it?

I'm using 2 Scythe Slip Streamed 120 MM fans.

Number SY1225SL12M

1,200 RPM, 68 cfm -

Lowered my load temps fron 70+ C to 50-51C

Well obviously you're getting good temps, I'm sure push-pull plus case fan positions and your low voltage overclock helps

, so it doesn't matter at this point but...slipstreams really aren't great heatsink fans imo for tight-finned sinks like the Megahalems and TRUE, their CFM ratings are totally fudged and they do not have good static pressure. In other words, they are fine case fans for more 'free air' applications or heatsinks without dense fins but there are better fans for heatsinks. Something to consider if you ever change cases and it doesn't work out as well
