I saw that also but have heard that kits are not the way to go.

You're right. Better if you'll select a set from separate parts, like i'm, for example.

[bluestang]

I know that's the default statement. But this has a top notch CPU block, pump, and a very good radiator. For just CPU cooling this is more than I would need to run and 45nm Dual or Quad core. Ans at ~$225-250, the price is pretty reasonable compared to a custom setup. Not all kits are bad kits and some are very very good.

Im all for a kit, for one it would save time picking out parts and paying for multiple shipping charges. I just wonder what kind of results I will see. 5 to 7c lower doesnt put me where I need to be. Maybe Im not going to find what I need using water IDK. Maybe xtreme cooling is what I need but IDK if there are any that can be run for extended periods of time. I mostly play games and just fool around with oc'ing in between gaming.

Nub, what would really make a difference would be cold air going into the radiator fins.

So the kit can be cheap, but if you manage to use laundry dryer vents and pull the cold air into the rad fan's the temp will drop big time.

Hey guys this is what I have. Been priming for 8 hours now. Ran the intel burn test 15 times no problem. The DDR3 ver of this mobo sucks for clocking ram. Good luck getting it over 1600MHZ unless your using the bugged 3:5. Anyone got getter ram speeds? have you seen that it seems like you have to run a little more then the rated voltage to the ram?

The back of my pc is about 1ft away from an AC window unit, it would blow right on the radiator if mounted on the back of my 1200 antec. What kit or parts would you suggest? I have never tried water cooling and have no idea what I need. Thanks.

Tell me about it, I have almost the same problem, I get past 1650 with 2x2 Transcend 1800C8 but then it starts to get me problem and the same with 2x2 Crucial Value 1333C9 (D9KPT), I don´t even get my 2x1 Dominator 1800C7 to run at rated speed.

I have seen one that have achive 2x2 DDR3-2000MHz @ 1,92 (Crucial Value 1333C9 ) on this EP45T but it was with a dual, it was pangingIII, check this out, don´t know how he did it but he did.

Leeghoofd had the same problem, a think that he had a little better luck with those low volt Elpida Hyper.

The good thing is that run a 45nm quad ~FSB 500 with these UD3 board is so easy. , I just love it.

But FSB 500 ram DDR3-1600C7 is a little better then FSB 500 ram DDR2-1200C5 though, hope that cheer you up a little.

[hank123]

right on thanks! Looks like F1 bios could have something to do with it. man thats some fast ram!

[radaja]

been gone for a couple of weeks(no internet) but i got to say there are some great results
that have been posted while i was away.
P.S. great to see Jor3lBR back in action in the thread,went quiet for awhile.

[LiquidReactor]

Hey,

I can't seem to be able to go 1200Mhz+ DDR2 on my OCZ PC2 9200 Reapers. I used to be able to hit 1206Mhz Pl8 no problem 12 hours Prime blend stable when I tested with 8800 Ultra as primary gpu but now with HD 4870x2 as soon as ram hits 1200Mhz or higher (2.50A multiplier strap) Prime blend throws errors within an hour.

Running F5 bios, do I just need to tweak the Cpu VTT, Mch core/Mch ref values more?

[magnifico]

hello guys...

i have a problem with my new platform...

can i say what is max pll voltage on my gigabyte ud3p?

my cpu is an q9650@4300 vcore 1.375 100% stable on asus maximus formula

i don't know max voltage for daily use and because now prime 95 give me an error on one of 4 cores...

this is my actual settings from bios and easy tune



thanks in advance

magnifico

Your MCH Ref is off for a Q9650.

Lower your PLL tp 1.5v and raise your MCH Ref to 0.800 thru easytunes6.

See if that does the trick.

@hank123

I see that you still hanging on to that EP45T even though you don´t love it.

[rubber5]

i have just upgraded to 8gb of memory i have 2x TW2X4G6400C4PRO 2x2gb
and i have had the rig at 3.5ghz overclock with only 2 sticks of 2gb but getting the cpu @3.5 means the memory goes to 876mhz.
But i dont know if its safe to overclock memory and how long it will last at 876mhz i have 4sticks of 2gb now can anyone help me becuse i cant get the memory any lower in speed.
The motherbord im using is the ep45-ud3r i have a gtx 280 no oc and all i want to know is i have the cpu @3.2 and it is stable is it worth going for 3.5 and overclockg the memory as well im curently getting 16553 on 3d mark 06 if it helps
thanks guys i hope you can help

ya dude I have a Rampage Formula coming in. kind of sucks that its only ddr2 but it will be fun to play with.


The FSB is sweet on this mobo. right now got the e8500 running at 4.5 with 1.360V under load. had to bump the voltage a little failed prime95 after 13 hours 1 min

[TooFastForYa]

Can someone please guide me to a good starting template for a Q9650 & UD3P running at 4050? Just upgraded to this board today.

System info:
Q9650 Batch # L836B361 w/ VID of 1.2250
Gigabyte EP45-UD3P
G.Skill 2x2GB Pi Black DDR2 800 F2-6400CL4D-4GBPI-B
Core-Contact Freezer
Antec P180
Corsair 520HX
Thanks

Biggest thing is figuring out the % stuff. You gott know how to do math. Its gonna take some reading. the more you read the more you learn. the more you learn and really understand the HIGHER your OC will be. I have spent 30+ hours getting to know this board. Ya i still think the DDR3 ver sucks over the DDR2 ver but its still a great mobo for the price.

Hope you gonna like your RF, it´s stable and robust board, not the best for quad though.

If you want to run DDR3 I think that you should go i7, LGA775 is no go with DDR3.

I agree, I just love the FSB on UD3.

BTW, it seems like Gigabyte gonna release some new boards and this one should probably be the last ultimate LGA775 DDR2 board to have.

Awaiting an EP45T UD5 !! My Gb contact already had a hard time getting me a P45 sample as most of the boards are EOL once I5 Pops up in the shops...

[Dr.Paneas]

Hello there,

I own a UD3R and a e8500 (e0 stepping).
So, can you help me overclock this little monster ? ( My heatstink is Ultra 120 Extreme)

Any tips ?
What bios version should I use ?
Should I enable LLC ?
Should I mess with GTL Voltages or set them AUTO ?

\Thank you in advance!

You gonna roll the dice for one more EP45T, do you hope that this UD5 are better then your old EP45T- UD3, memory wise.

Do you know when they gonna be released?

I hope that I get hold on one EP45-UD5 before i5 though.

I finally got around to get this template for you guys, sorry the delay...

This setup came with the summer. I know I was already with 4700Mhz stable setup but this 4500Mhz/4Gb_1200DDR2 is good because of the low voltages and maybe possible on AIR with good Hs's out there. the mem's used where the well known G.Skill's PI edition (4Gb).

Volts used: 1.32vcore / 1.34vtt / 1.50pll / 2.0vdimm / 1.40mch

CPU Cooling: WC Swiftech MCR : Thermalright XWB-1 : MCP655 : NBM-MAT 120mm Fans : 15000 BTU AC in the Room

Bios: F8. (works with any BIOS actually).

This also proves that degradation on these Quads is almost a Myth, this CPU is the same I had from the start and every time I prime95 an old setup I had it just blows the barrier of low voltages all the time. I need less and less voltages to achieve same clocks. This same cpu and gskill had to endure this to be here: http://www.xtremesystems.org/forums/...d.php?t=227129

I always try to send as many pics of the entire testing process (beginning/middle/end) because it shows the real voltage used with all the tests.

...

Some settings will be hardware specific, like CPU and MCH ref and also memory settings will vary according to what your ram is capable of.

Thanks man. Testing now. What are your secondary mem timings and pl? or did i miss it?

Hello there,

Any tips ? A sig with your hardware should be nice, easier to help then.
What bios version should I use ? F9 should be fine.
Should I enable LLC ? Yes, sure, seems that Gigabytes LLC is work just fine.
Should I mess with GTL Voltages or set them AUTO ? Recommend you to not set them on auto, set CPU ref to 0.760 and MCH ref to ~0,720, one step up or down from 0,720 should do it.

\Thank you in advance!

What kind of ram do you have?

Here´s a screenie with a E8400 @ 500 4,0GHz and ram 2x1 @ 1200 CAS5 tRD8 (Static Read Value), hope it can help some.

Shouldn´t be any problems for you to reach that (with lower core volt), you should be able to reach 4,25 - 4,50 with a bus speed 500 and ram at DDR2-1000 (use Latch 400).
