Wow this thread has really grown since I was here last....... glad to see it's still live and kicking.

I'm working with a Q9650 and a UD3P. I'm asking if there are any special or commonly used settings for high FSB (500+).

I'm at 9x500 right now but can't go any higher. Haven't really changed any settings other than:

CPU PLL
CPU Termination
DRAM Voltage
MCH Core

Any thoughts would be greatly appreciated. Thanks.

Maybe these will help you a little bit.

I'm sure it can be done with lower voltage than I used, I was just a little too lazy to try.

wow, your almost there. I am not even close yet. 32m @ 5g's would be sweet though. especially on air. I need to get busy.

I raised vcore a notch. (That is both cores no waz.)

This is from research conducted. In this case, I believe it was advice given by LSDMEASAP at the Tweaktown Gigabyte support site. I regard LSDMEASAP as the the Subject Matter Expert on this and othe Gigabyte boards. Other folks on that site are good as well, but he is, to me, the most credible source I have found.

awesome coop and with a great vcore

man i got to get this to work(32m at 5ghz)

Thanks you very much. I'll try this now that I'm home. I'll let you know how it turns out.

**andressergio** · 07-01-2009, 05:11 PM

first test with old batch Crucial Ballistix 2x1GB but i think i have to tune the timmings better, its my first test with 2x1GB in this mobo

sorry i added the memset screen later as i forgot

i gave 2,3Vdimm to get that speed with a fan over them

Cheers

Sergio

Nice man but only 2.3v on D9? They are teasing you from the slot saying "that's all you got old man"

arent this crucial known for die fast ? thats why i gave only 2,3, do you think i can go for more ?

Cheers
Sergio

**Blue Storm** · 07-02-2009, 11:57 AM

I think, you can gou about 2.5V with additional cooling

today I was testing Crucial Ballistix with D9 with 2.5V but it didn't fit in ASUS Commando and it went with 620MHz (effective 1240MHz)

**xguntherc** · 07-02-2009, 02:18 PM

I've finally took the leap and got myself a EP45.. I'm hoping you guys could give me some oc pointers regarding this board.. I have the EP45-UD3L. as it's a cheap build with backup parts, and then will become my parents as they need one.

for now, here's what I've got on this. UD3L, with a Q6600 1.21 VID L737, with OCZ Blade PC2-8500, and it seems to be holding up just fine. I'm pretty impressed with the EP45 so far, I've managed on only my second try to get 3.33 Ghz 1112 MHz RAM with 1.21 vcore and 2.15 on ram and it's looking pretty stable with OCCT so far. I'm impressed.

**stasio** · 07-02-2009, 10:29 PM

New BIOS:

GA-EP45T-UD3R - F7a
GA-EP45-UD3P - F10b
GA-EP45-UD3R - F10c

No info.
Seems to have new AHCI ROM.....

**xzulu** · 07-03-2009, 04:38 AM

Guys, where's the motherboard temperature die on the board? Just wondering.....

I got a new video card and my motherboard temps went up like 2C, seems like the motherboard temp die is somewhere near the video card and getting some of the heat. Thanks!

BTW, nice OC's Sergio and Radaja and coop!!

**radaja** · 07-03-2009, 07:54 AM

thanks Xzulu. the temp sensor
seems to be near the SB area,so the makes
sense that temps went up a bit

Does NOT have new AHCI ROM

Sucks for us.

Finally got 4.3 stable- 50 loops of intel burn, all day prime 95 but want more

Can boot and run at 4.5, just cant pass any stress tests

Heres where I'm at now:

cpu 9x500

vcore 1.375
term 1.34
ppl 1.5
ref .848

mch

core 1.4
ref .888

Mem 333, 2.0b standard

5/5/5/15

2.12
1.06

all others auto

heres my system:

ep45 ud3r f9
q9650, lapped
true lapped w/ ultra kaze 2ks in push-pull, as5
nb, mosfets all have upgraded hs/fan
muskin 1066- 4x2g=8g ( 3g in ramdisk) w/ hsf
corsair 750w
4870x2 @800/1000
case has 6 ultrakaze 2ks, very well vented
2 wd 640g black in raid 0
windows 7 64 bit

tired of waiting on the ocz 1200 blades to come in, dunno why i cant get a good clock now at 2.0b

i know i need to do something about cooling, not in the budget atm- intel burn is tickling 90 now with ambient 28-29 here, nb 93 loaded

ive gone up, down and sideways in bios, im at a loss where to go

all the big kids can get 4.5- i wanna run it too- help!!

thx

**coop** · 07-03-2009, 03:49 PM

enough with IB and P95. if I saw 90 (70) I'd freak. I have a suggest for 9x500. Bump cpu ref up a notch then another if that don't work. Keep all else the same. Maybe mch a couple notches too. (1.44?) Quite a load of ram there.

*********I was going over the above and was thinking of what I was using. Don't do that. For 1.34vtt try cpu ref of .903 or up a notch. Then your mch ref seems high already. Try .808 You may need more mch core like I mentioned due to ram. Which brings me to here. You won't be able to boot with 333, 2.0 with 5/5/5/15. You will need 4/4/4/12. Also 400 will be best start.

also your NB is way too hot (93c)

Hey thanks for the heads up!

I'll try to put a fan in that area.

Im booting with the setting I listed.

I will try your reccomendations for ref now, then try mem at 4/4/4/12, but dont think it will run that fast. Will also try 400 (d), but only have 1066 so will have to run it at 800- it wont go much over 1130 so 1200 is out with these muskins...

thanks

realize im too hot, will do water when i can afford- other than stress testing it doesnt run that hot. gaming it only runs 62-65nb and 60-61 cpu, but 4870 luv the air and runs at 60 maxed out so im good there

**Hoss331** · 07-03-2009, 06:06 PM

I figured I would play with the xeon some tonight. I had a 9.298 but got greedy and lost it

, im still playing with it so maybe ill get it again or just try for higher.

Nice X3380 Hoss

, when you get tired of it please borrow it to me so I can give it a go too

How does it compare to the Q9650 at 5Ghz?

You should get below 9.2s on the X3380 I got that with my Q9650 with slower speeds (4900Mhz):

**Hoss331** · 07-03-2009, 06:28 PM

Got it back. Yea it should be able to go lower but im currently using my everyday untweaked win7. Do you have any OS tweaks you want to share?

**thebluemeanie1** · 07-03-2009, 06:57 PM

Nice to see Jor3lBR posting a 1M run on XP. I was working on beating his Vista time but even my best was .010 seconds slower.

Only two Pi 1M tweaks I can think of that make major differences are use Windows XP and F4-4 BIOS if you are using the EP45-UD3P.

**Hoss331** · 07-03-2009, 06:59 PM

How big of a difference with F4-4?
